  • Does Imaging Modality Used for Percutaneous Renal Access Make a Difference? A Matched Case Analysis
  • 2013
  • In: Journal of Endourology. - : Mary Ann Liebert Inc. - 0892-7790 .- 1557-900X. ; 27:1, s. 24-28
  • Journal article (peer-reviewed)abstract
    • Objective: To assess perioperative outcomes of percutaneous nephrolithotomy (PCNL) using ultrasound or fluoroscopic guidance for percutaneous access. Methods: A prospectively collected international Clinical Research Office of the Endourological Society (CROES) database containing 5806 patients treated with PCNL was used for the study. Patients were divided into two groups based on the methods of percutaneous access: ultrasound versus fluoroscopy. Patient characteristics, operative data, and postoperative outcomes were compared. Results: Percutaneous access was obtained using ultrasound guidance only in 453 patients (13.7%) and fluoroscopic guidance only in 2853 patients (86.3%). Comparisons were performed on a matched sample with 453 patients in each group. Frequency and pattern of Clavien complications did not differ between groups (p = 0.333). However, postoperative hemorrhage and transfusions were significantly higher in the fluoroscopy group: 6.0 v 13.1% (p = 0.001) and 3.8 v 11.1% (p = 0.001), respectively. The mean access sheath size was significantly greater in the fluoroscopy group (22.6 v 29.5F; p < 0.001). Multivariate analysis showed that when compared with an access sheath <= 18F, larger access sheaths of 24-26F were associated with 3.04 times increased odds of bleeding and access sheaths of 27-30F were associated with 4.91 times increased odds of bleeding (p < 0.05). Multiple renal punctures were associated with a 2.6 odds of bleeding. There were no significant differences in stone-free rates classified by the imaging method used to check treatment success. However, mean hospitalization was significantly longer in the ultrasound group (5.3 v 3.5 days; p < 0.001). Conclusions: On univariate analysis, fluoroscopic-guided percutaneous access was found to be associated with a higher incidence of hemorrhage. However, on multivariate analysis, this was found to be related to a greater access sheath size (>= 27F) and multiple punctures. Prospective randomized trials are needed to clarify this issue.

  • Experimental in vivo model to evaluate the impact of Cernitin™ on pain response on induced chronic bladder inflammation
  • 2022
  • In: Scandinavian Journal of Urology. - : Medical Journals Sweden AB. - 2168-1805 .- 2168-1813. ; 56:4, s. 320-328
  • Journal article (peer-reviewed)abstract
    • Objective: Inflammation of the urinary bladder may cause burdensome pain also called bladder pain syndrome (BPS). A limitation in understanding BPS pathophysiology is the lack of appropriate preclinical model. Previously published clinical and preclinical studies revealed positive impact of Cernitin™ on pain relief in chronic prostatitis. The objective of this study was to evaluate the effects of Cernitin™ on induced inflammation of the urinary bladder in rats. We also sought to identify biomarkers which might play a role in the management of BPS. Materials and methods: Cystitis was induced by injection of cyclophosphamide (CYP) in female rats. Thereafter, animals were randomly divided into four treatment groups and two control groups. Evaluation of pain scores was assessed by von Frey assay. Expression of pain- and pro-inflammatory biomarkers was determined by enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry. Results: Treatments with Cernitin™ displayed significant anti-nociceptive effects on CYP-induced visceral pain (p <.01). In contrast, vehicle-treated animals showed high pain score even at the lowest force. Furthermore, results of ELISA showed that Cernitin™-treated animals had significantly reduced levels of COX-2 (T60, p <.01; GBX, p <.05) in bladder tissue homogenate. Immunohistochemical (IHC) staining of bladder tissues showed that Cernitin™-treated animals exhibited less CD45-positive cells, while massive CD45-positive cells infiltration was detected in vehicle-treated animals. IHC also revealed lower SP and PGD2 expression levels in Cernitin™-treated tissues. Conclusions: Cernitin™ components reduced pain score and inflammatory marker COX-2. Our findings suggest a potential therapeutic role for Cernitin™ in the management of BPS.

  • Asymptomatic Bacteriuria in Clinical Urological Practice: Preoperative Control of Bacteriuria and Management of Recurrent UTI.
  • 2016
  • In: Pathogens. - : MDPI AG. - 2076-0817. ; 5:1
  • Journal article (peer-reviewed)abstract
    • Asymptomatic bacteriuria (ABU) is a common clinical condition that often leads to unnecessary antimicrobial use. The reduction of antibiotic overuse for ABU is consequently an important issue for antimicrobial stewardship and to reduce the emergence of multidrug resistant strains. There are two issues in everyday urological practice that require special attention: the role of ABU in pre-operative prophylaxis and in women affected by recurrent urinary tract infections (rUTIs). Nowadays, this is the time to think over our practice and change our way of thinking. Here, we aimed to summarize the current literature knowledge in terms of ABU management in patients undergoing urological surgery and in patients with rUTIs. In the last years, the approach to patient with ABU has changed totally. Prior to all surgical procedures that do not enter the urinary tract, ABU is generally not considered as a risk factor, and screening and treatment are not considered necessary. On the other hand, in the case of all procedures entering the urinary tract, ABU should be treated in line with the results of a urine culture obtained before the procedure. In patients affected by rUTIs, ABU can even have a protective role in preventing symptomatic recurrence, particularly when Enterococcus faecalis (E. faecalis) has been isolated.

  • Impact of Cernitin™ on induced chronic prostatitis in animal model for understanding management of lower urinary tract symptoms
  • 2021
  • In: Phytomedicine Plus. - : Elsevier BV. - 2667-0313. ; 1:4
  • Journal article (peer-reviewed)abstract
    • Background: Cernitin™ pollen extracts (brand name Cernilton®) alleviates symptoms related to common lower uro-genital tract disorders in men. The underlying mechanisms are ill-defined but the inflammatory pathway could be one of them. In a previous in vitro study it was shown that Cernitin™ induce a regulatory effect on inflammatory parameters. Methods: In this study, male Sprague Dawley rats were used to validate the effects of Cernitin™ in chronic prostatitis and benign prostatic hyperplasia. Pain was assessed by von Frey assay. Results: Cernitin™ exhibited significant pain relief in the induced prostatitis rat model and was associated with a significant decrease in the intraprostatic level of COX-2 and MCP-1 in the prostatic tissue homogenates. In a parallel study, Cernitin™ treatment led to a significant decrease in prostate weight in rats with testosterone induced BPH. Concurrently, a significant decrease in the percentage of proliferation marker, Ki-67, and androgen receptor expressing cells was observed. Similarly, a low level of cytoplasmic 5α-reductase expression was observed in Cernitin™- and finasteride-treated animals. Conclusion: The current in vivo experiments support the use of Cernitin™ as an anti-inflammatory and symptom reducing agent that could, in part, explain the impact of Cernitin™ on the management of chronic pelvic pain in men.

  • Preoperative Antibiotics Before Endourologic Surgery: Current Recommendations
  • 2009
  • In: Journal of Endourology. - : Mary Ann Liebert Inc. - 0892-7790 .- 1557-900X. ; 23:10, s. 1567-1570
  • Journal article (peer-reviewed)abstract
    • The use of antibiotic prophylaxis is an accepted and widely practiced feature of modern surgery. The prevention and control of infection is a priority in healthcare worldwide, and the emergence of antibiotic resistance is a global phenomenon. Hence, rational use of antibiotics is essential. We discuss the guidelines published with regard to endourologic procedures and review the limited evidence currently available. There should be subclassification of endourologic procedures based on infection risk to guide sensible use of antibiotics before surgery.

  • Categorisation of Complications and Validation of the Clavien Score for Percutaneous Nephrolithotomy
  • 2012
  • In: European Urology. - : Elsevier BV. - 1873-7560 .- 0302-2838. ; 62:2, s. 246-255
  • Journal article (peer-reviewed)abstract
    • Background: Although widely used, the validity and reliability of the Clavien classification of postoperative complications have not been tested in urologic procedures, such as percutaneous nephrolithotomy (PCNL). Objective: To validate the Clavien score and categorise complications of PCNL. Design, setting, and participants: Data for 528 patients with complications after PCNL were used to create a set of 70 unique complication-management combinations. Clinical case summaries for each complication-management combination were compiled in a survey distributed to 98 urologists, who rated each combination using the Clavien classification. Outcome measurements and statistical analysis: Interrater agreement for Clavien scores was estimated using Fleiss' kappa (kappa). The relationship between Clavien score and the duration of postoperative hospital stay was analysed using multivariate nonlinear regression models that adjusted for operating time, preoperative urine microbial culture, presence of staghorn stone, and use of postoperative nephrostomy tube. Results and limitations: Overall interrater agreement in grading postoperative complications was moderate (kappa = 0.457; p < 0.001). Agreement was highest for Clavien score 5 and decreased with lower Clavien scores. Higher agreement was found for Clavien scores 3 and 4 than in subcategories of these scores. Postoperative stay increased with higher Clavien scores and was unaffected by inherent differences between study centres. A standard list of post-PCNL complications and their corresponding Clavien scores was created. Conclusions: Although the Clavien classification demonstrates high validity, interrater reliability is low for minor complications. To improve the reliability and consistency of reporting adverse outcomes of PCNL, we have assigned Clavien scores to complications of PCNL. (C) 2012 European Association of Urology.

  • The effects of Cernitin® on inflammatory parameters and benign prostatic hyperplasia : An in vitro study
  • 2019
  • In: Phytotherapy Research. - : Wiley. - 0951-418X .- 1099-1573. ; 33:9, s. 2457-2464
  • Journal article (peer-reviewed)abstract
    • The pollen extract Cernitin® is widely used for treatment of benign prostatic hyperplasia (BPH) and non-bacterial chronin prostatitis. However, little is known about the underlying molecular mechanisms to explain the clinical effects of Cernitin®. In this study, we sought to investigate the cellular mechanisms by which Cernitin® induces its effects on human prostatic cell lines BPH-1 and WPMY-1 and primary human peripheral blood mononuclear cells (hPBMCs) in vitro. We examined the effects of Cernitin® formulas T60 and GBX on the protein expression, proliferation, and cytokines production. Results revealed that Cernitin® upregulated antiinflammatory cytokine interleukin (IL)-10 and its receptors IL-10RA and IL-10B in addition to the upregulation of tumour necrosis factor-related apoptosis-inducing ligand in hPBMC. Interestingly, the levels of proinflammatory cytokines IL-6 and IL-8 were also increased. Furthermore, Cernitin® had significantly increased the level of IL-10 in BPH-1 and WPMY-1 cells. The level of IL-6 was also significantly increased in these cells although both T60 and GBX inhibited STAT-3 phosphorylation. Moreover, Cernitin® formulas had significantly reduced androgen receptor and prostate-specific antigen protein expression in stromal cells (p <.05). Treatment with GBX and T60 had significantly inhibited proliferation of BPH (p <.001) and stromal cells (p <.05), in a dose-dependent manner. Taken together, treatment with Cernitin® showed to regulate cytokines level in both prostatic cell lines and hPBMCs and it was associated with decreased androgen receptor and prostate-specific antigen levels WPMY-1 cells.

  • Primary seminal vesicle carcinoma detected at transurethral resection of prostate
  • 2007
  • In: Urology. - : Elsevier BV. - 1527-9995 .- 0090-4295. ; 69:4
  • Journal article (peer-reviewed)abstract
    • We present a case of primary seminal vesicle carcinoma detected at transurethral resection. The clinical presentation, radiologic findings, and pathologic features of these tumors are reviewed. Grossly, seminal vesicle carcinoma is poorly circumscribed and solid or solid/cystic and may be misinterpreted as an abscess or hemorrhage on radiologic examination. Although a definitive diagnosis often cannot be given until after complete resection, we describe the findings indicative of seminal vesicle origin, including papillary histologic architecture, sometimes with mucinous differentiation, and a characteristic immunophenotype positive for CA-125 and cytokeratin 7, but negative for prostate-specific antigen and cytokeratin 20.

  • Urachal signet-cell adenocarcinoma
  • 2009
  • In: Scandinavian Journal of Urology and Nephrology. - : Informa UK Limited. - 0036-5599 .- 1651-2065. ; 43:1, s. 88-91
  • Journal article (peer-reviewed)abstract
    • This report presents two cases of urachal signet-cell adenocarcinoma (USCA). Two men, aged 53 and 51 years, presented with haematuria. Cystoscopy showed tumours in the dome of the bladder and transurethral resection revealed signet ring cell carcinoma. They both underwent cystoprostatectomy but died of metastatic disease after 14 and 26 months. USCA is a very rare tumour with poor prognosis. Only 25 cases have been reported. The tumours have a specific gross and microscopic morphology but must be distinguished from metastases of signet ring cell originating from other sites. Immunohistochemistry is helpful for the determination of the primary site.

  • Antibiotic prophylaxis in urological surgery, a European viewpoint.
  • 2011
  • In: International Journal of Antimicrobial Agents. - : Elsevier BV. - 1872-7913 .- 0924-8579. ; 38, s. 58-63
  • Journal article (peer-reviewed)abstract
    • Surgical site infections (SSI) including urinary tract infections (UTI) cause a significant morbidity in urological surgery. Antibiotic prophylaxis is one of several factors impacting on infection rates. Antibiotic prophylaxis is relevant only for clean and clean-contaminated operations and in the absence of bacterial growth in the urine. Strict classification of urological procedures is lacking, but a proposal is presented elsewhere. Only TURP and transrectal core prostate biopsy are well documented. The present review confirms that there is a lack of hard data, insufficient consistency in classification and definitions, and that new well-powered RCT and large multicentre quality cohort studies including risk factor analysis are necessary to improve recommendations for antibiotic prophylaxis in urologic surgery.

  • Controlled trial of a short and a prolonged course with ciprofloxacin in patients undergoing transurethral prostatic surgery
  • 1987
  • In: European Journal of Clinical Microbiology and Infectious Diseases. - 0722-2211. ; 6:1, s. 11-17
  • Journal article (peer-reviewed)abstract
    • The efficacy of a short (Group I) and a prolonged (Group II) course with ciprofloxacin was assessed in patients undergoing transurethral prostatic resection for benign hyperplasia or cancer of the prostate and compared with that of controls without antibiotic (Group III). Both regiments significantly reduced the frequency of postoperative bacteriuria (p less than 0.01) and of severe infectious complications (p = 0.004) as compared to the controls. Both regimens were equally effective in preventing perioperative and postoperative acquisition of bacteriuria in patients without bacteriuria at surgery. In patients with bacteriuria before surgery, bacteriuria was found postoperatively in 35% in Group I and 10% in Group II (p = 0.012), but in 82% of the patients in Group III. Ciprofloxacin inhibited all but 7 of 176 bacterial strains at an MIC of less than or equal to 1 microgram/ml. Given orally ciprofloxacin is a valuable alternative antimicrobial for use in conjunction with transurethral prostatic resection. A short course is sufficient for prophylaxis, and adequate therapy is achieved with a prolonged regimen.

  • Tailored perioperative antimicrobial prophylaxis in urological surgery : myth or reality?
  • 2017
  • In: Current Opinion in Urology. - 0963-0643 .- 1473-6586. ; 27:2, s. 112-119
  • Research review (peer-reviewed)abstract
    • Purpose of review The controversies surrounding perioperative antimicrobial prophylaxis (AMP) are about the use and especially misuse of antibiotics. The overall lack of evidence to facilitate a rational perioperative AMP policy in urological surgery and the postoperative infectious complications remain a challenge. Therefore, a basic tool to aid decision-making would be useful. A model based on the patients' risk factors, the level of contamination and grading of surgical procedures is discussed.Recent findings A series of studies have shown that infectious complications and healthcare-associated infections remain consistently at an average of 10%, with a great variation in frequency dependent on the patients' preoperative status and the type, severity and contamination level of the surgical procedure. Preoperative patient assessment and preparation are key factors for well tolerated surgery and recovery. Adherence to the guidelines appears to reduce both the prescription of antimicrobials and the total costs without risking the patient outcome. Several studies of a series of interventions such as cystoscopy, endoscopic stone surgery and selected clean-contaminated interventions give support to the model. Bacteriuria, upgrading the patient to the contaminated level, requires preoperative control.Summary The discussed model assists the urologists in decision-making on perioperative AMP and contributes to a responsible use of antibiotics.

  • Preoperative assessment of the patient and risk factors for infectious complications and tentative classification of surgical field contamination of urological procedures.
  • 2011
  • In: World Journal of Urology. - : Springer Science and Business Media LLC. - 1433-8726 .- 0724-4983.
  • Journal article (peer-reviewed)abstract
    • PURPOSE: To assess the patient and identify the risk factors for infectious complications in conjunction with urological procedures and suggest a model for classification of the procedures. METHOD: Review of literature, critical analysis of data and tentative model for reducing infectious complications. RESULTS: Risk factors are bound to the patient and to the procedure itself and are associated with the environment where the healthcare is provided. Assuming a clean environment and sterile operation field, a five-level assessment ladder related to the patient and type of surgery is useful, considering: (1) the ASA score, (2) the general risk factors, (3) the individual endogenous and exogenous risk factors, (4) the class of surgery and the potential bacterial contamination burden and (5) the level of severity and difficulty of the surgical intervention. A cumulative approach will identify the level of risk for each patient and define preventive measures, such as the type of antibiotic prophylaxis or therapeutic measures before surgery. There are data suggesting that the higher the ASA score, the higher is the risk of infectious complication. Age, dysfunction of the immune system, hypo-albuminaemia/malnutrition and overweight, uncontrolled blood glucose level and smoking are independent general risk factors, whilst bacteriuria, indwelling catheter treatment, urinary tract stone disease, urinary tract obstruction and a history of urogenital infection are specific urological risk factors. There is inconclusive evidence for most other reported risk factors. The level of contamination of the surgical field is of utmost importance as are the procedure-related factors, and the sum of these have to be reflected on for the subsequent perioperative management of the patient. CONCLUSIONS: It is essential to identify and control risk factors to minimize infectious complications in conjunction with urological procedures. Our knowledge is limited and clinical research and quality registries analysing risk factors must be undertaken. We propose a working basis for assessment of patients' risk factors and classification of urological procedures.

  • Should All Patients with Non-Muscle-Invasive Bladder Cancer Receive Early Intravesical Chemotherapy after Transurethral Resection? The Results of a Prospective Randomised Multicentre Study.
  • 2009
  • In: European Urology. - : Elsevier BV. - 1873-7560 .- 0302-2838. ; 55, s. 773-780
  • Journal article (peer-reviewed)abstract
    • BACKGROUND: To decrease recurrences in non-muscle-invasive bladder cancer (NMIBC), the European Association of Urology (EAU) guidelines recommend immediate, intravesical chemotherapy after transurethral resection (TUR) for all patients with Ta/T1 tumours. OBJECTIVE: To study the benefits of a single, early, intravesical instillation of epirubicin after TUR in patients with low- to intermediate-risk NMIBC. DESIGN, SETTING, AND PARTICIPANTS: In this prospective randomised multicentre trial, 305 patients with primary as well as recurrent low- to intermediate-risk (Ta/T1, G1/G2) tumours were enrolled between 1997 and 2004. Patients were randomly allocated to receive 80mg of epirubicin in 50ml of saline intravesically within 24h of TUR or no further treatment after TUR. MEASUREMENTS: The primary end point was time to first recurrence. RESULTS AND LIMITATIONS: A total of 219 patients remained for analysis after exclusions. The median follow-up time was 3.9 yr. During the study period, 62% (63 of 102) of the patients in the epirubicin group and 77% (90 of 117) in the control group experienced recurrence (p=0.016). In a multivariate model, the hazard ratio (HR) for recurrence was 0.56 (p=0.002) for early instillation of epirubicin versus no treatment. In a subgroup analysis, the treatment had a profound recurrence-reducing effect on patients with primary, solitary tumours, whereas it provided no benefits in patients with recurrent or multiple tumours. Furthermore, patients with a modified European Organisation for Research and Treatment of Cancer (EORTC) risk score of 0-2 with and without single instillation had recurrence rates of 41% and 69%, respectively (p=0.003), whereas the corresponding rates for those with a risk score of >/=3 were 81% and 85%, respectively (p=0.35). CONCLUSIONS: A single, early instillation of epirubicin after TUR for NMIBC reduces the likelihood of tumour recurrence; however, the benefit seems to be minimal in patients at intermediate or high risk of recurrence. Future trials will determine the value of early instillation in addition to serial instillations in NMIBC.

  • The Value of the UroVysion((R)) Assay for Surveillance of Non-Muscle-Invasive Bladder Cancer.
  • 2008
  • In: European Urology. - : Elsevier BV. - 1873-7560 .- 0302-2838. ; 54:2, s. 402-408
  • Journal article (peer-reviewed)abstract
    • OBJECTIVE: Patients with non-muscle-invasive bladder cancer are traditionally followed by repeat cystoscopy and urine cytology. A fluorescence in situ hybridisation technique called UroVysion((R)) (UV) is now available for clinical diagnosis of urothelial cancer cells. The aim of the present study was to compare UV analysis with routine follow-up methods. METHODS: We studied an unselected cohort of patients undergoing cystoscopy follow-ups at two Swedish centres in 2004-2005. All patients were investigated by cystoscopy, cytology, and UV assay. The UV assay was evaluated with regards to sensitivity, specificity, and positive predictive value for tumour recurrence. RESULTS: In all, 159 cases were analysed. UV had a 30% overall sensitivity for the 27 biopsy-proven recurrences and 70% sensitivity for high-risk tumours (pT1 and carcinoma in situ [CIS]). The specificity of UV was 95%. UV detected all six CIS cases in the study and was predictive in two additional patients who developed CIS within 1 yr of inclusion. Cytology was positive in four of those eight CIS cases and atypical in the other four. CONCLUSIONS: The UV assay cannot replace cystoscopy for surveillance of patients with non-muscle-invasive bladder cancer, but it may be valuable as a supplement to traditional measures for detecting CIS. Before any conclusions can be drawn regarding the efficacy of novel markers of bladder cancer, they must be studied in bladder cancer patients undergoing endoscopic surveillance.

    • The efficacy of a short (Group I) and a prolonged (Group II) course with ciprofloxacin was assessed in patients undergoing transurethral prostatic resection and compared with that of controls without antibiotic (Group III). Both regimens significantly reduced the frequency of post-operative bacteriuria (p less than 0.01) and of severe infectious complications (p = 0.004) compared to the controls.

  • Community-onset urosepsis: incidence and risk factors for 30-day mortality - a retrospective cohort study
  • 2022
  • In: Scandinavian Journal of Urology. - : Medical Journals Sweden AB. - 2168-1805 .- 2168-1813. ; 56:5-6, s. 414-420
  • Journal article (peer-reviewed)abstract
    • Background Urosepsis is a life-threatening condition that needs to be addressed without delay. Two critical issues in its management are: (1) Appropriate empirical antibiotic therapy, considering the patients general condition, comorbidity, and the pathogen expected; and (2) Timing of imaging to identify obstruction requiring decompression. Objectives To identify risk factors associated with 30-day mortality in patients with urosepsis. Methods From a cohort of 1,605 community-onset bloodstream infections (CO-BSI), 282 patients with urosepsis were identified in a Swedish county 2019-2020. Risk factors for mortality with crude and adjusted odds ratios were analysed using logistic regression. Results Urosepsis was found in 18% (n = 282) of all CO-BSIs. The 30-day all-cause mortality was 14% (n = 38). After multivariable analysis, radiologically detected urinary tract disorder was the predominant risk factor for mortality (OR = 4.63, 95% CI = 1.47-14.56), followed by microbiologically inappropriate empirical antibiotic therapy (OR = 4.19, 95% CI = 1.41-12.48). Time to radiological diagnosis and decompression of obstruction for source control were also important prognostic factors for survival. Interestingly, 15% of blood cultures showed gram-positive species associated with a high 30-day mortality rate of 33%. Conclusion The 30-day all-cause mortality from urosepsis was 14%. The two main risk factors for mortality were hydronephrosis caused by obstructive stone in the ureter and inappropriate empirical antibiotic therapy. Therefore, early detection of any urinary tract disorder by imaging followed by source control as required, and antibiotic coverage of both gram-negative pathogens and gram-positive species such as E. faecalis to optimise management, is likely to improve survival in patients with urosepsis.

  • Critical review of current definitions of urinary tract infections and proposal of an EAU/ESIU classification system
  • 2011
  • In: International Journal of Antimicrobial Agents. - : Elsevier BV. - 1872-7913 .- 0924-8579. ; 38:Suppl., s. 64-70
  • Research review (peer-reviewed)abstract
    • Classification of urinary tract infections (UTI) is important for clinical decisions, research, quality measurement and teaching. Current definitions of UTI are above all based on the concept of the two main categories, complicated and uncomplicated UTI. The category "complicated UTI" especially is very heterogeneous and not always clear. We propose the EAU/ESIU classification system ORENUC based on the clinical presentation of the UTI, categorisation of risk factors and availability of appropriate antimicrobial therapy, which finally may result in the definition of UTI severity groups.

  • Genome-wide meta-analysis of 241,258 adults accounting for smoking behaviour identifies novel loci for obesity traits
  • 2017
  • In: Nature Communications. - : Springer Science and Business Media LLC. - 2041-1723. ; 8
  • Journal article (peer-reviewed)abstract
    • Few genome-wide association studies (GWAS) account for environmental exposures, like smoking, potentially impacting the overall trait variance when investigating the genetic contribution to obesity-related traits. Here, we use GWAS data from 51,080 current smokers and 190,178 nonsmokers (87% European descent) to identify loci influencing BMI and central adiposity, measured as waist circumference and waist-to-hip ratio both adjusted for BMI. We identify 23 novel genetic loci, and 9 loci with convincing evidence of gene-smoking interaction (GxSMK) on obesity-related traits. We show consistent direction of effect for all identified loci and significance for 18 novel and for 5 interaction loci in an independent study sample. These loci highlight novel biological functions, including response to oxidative stress, addictive behaviour, and regulatory functions emphasizing the importance of accounting for environment in genetic analyses. Our results suggest that tobacco smoking may alter the genetic susceptibility to overall adiposity and body fat distribution.

  • The Percutaneous Nephrolithotomy Global Study: Classification of Complications
  • 2011
  • In: Journal of Endourology. - : Mary Ann Liebert Inc. - 0892-7790 .- 1557-900X. ; 25:8, s. 1275-1280
  • Journal article (peer-reviewed)abstract
    • Purpose: This study evaluated postoperative complications of percutaneous nephrolithotomy (PCNL) and the influence of selected factors on the risk of complications using the Clinical Research Office of the Endourological Society (CROES) PCNL Global Study database. Patients and Methods: The CROES PCNL Global Study collected prospective data for consecutive patients who were treated with PCNL at centers around the world for 1 year. Complications were evaluated by the modified Clavien classification system. Results: Of 5724 patients with Clavien scores, 1175 (20.5%) patients experienced one or more complications. The most frequent complications were fever and bleeding. Urinary leakage, hydrothorax, hematuria, urinary tract infection, pelvic perforation, and urinary fistula also occurred in >= 20 patients in each group. The majority of complications (n = 634, 54.0%) were classified as Clavien grade I. Two patients died in the postoperative period. The largest absolute increases in mean Clavien score were associated with American Society of Anesthesiologists (ASA) physical status classification IV (0.75) or III (0.34), anticoagulant medication use (0.29), positive microbiologic culture from urine (0.24), and the presence of concurrent cardiovascular disease (0.15). Multivariate regression analysis revealed that operative time and ASA score were significant predictors of higher mean Clavien scores. Conclusion: The majority of complications after PCNL are minor. Longer operative time and higher ASA scores are associated with the risk of more severe postoperative complications in PCNL.

  • Single-Dose Antibiotic Prophylaxis in Core Prostate Biopsy: Impact of Timing and Identification of Risk Factors.
  • 2006
  • In: European Urology. - : Elsevier BV. - 1873-7560 .- 0302-2838. ; 50:4, s. 832-837
  • Journal article (peer-reviewed)abstract
    • objectives: To assess the level of infectious complications and the impact of timing of a single, prophylactic, oral dose of ciprofloxacin 750 mg given either 2 hours before or in conjunction with ultrasound -guided core biopsy of the prostate in men without recognised risk factors and to analyse potential risk factors. Methods: All men undergoing prostate biopsy for elevated prostate specific antigen or clinical suspected prostate cancer were enrolled in an open, comparative prospective study. Excluded were men with recognised risk factors for infective complications. Two end points were chosen: febrile genitourinary infection and the results of postbiopsy urine culture. Results: A total of 1322 prostate biopsy occasions were made in 1157 men. Twelve (0.9%) cases of febrile genitourinary infections were recorded, two of which had proven sepsis. Administrating the drug 2 hours before or at the time of biopsy (p > 0.5) showed no statistical difference. Eight of 12 patients were shown to have prebiopsy undisclosed risk factors. Four percent developed postbiopsy, asymptomatic, significant bacteriuria. In addition, three (27%) men with prebiopsy unrecognised bacteriuria, who were accidentally enrolled, developed febrile genitourinary infection; one had proven sepsis. Conclusions: A single high-dose of oral ciprofloxacin 750 mg can be administered in direct conjunction with prostate biopsy to men without recognised risk factors, keeping the infection rate at approximately 1%. Bacteriuria before biopsy is a major risk factor for infective complications. Attention given to recognising individual risk factors would reduce the risk of infection further.

  • Increasing rates of urinary- and bloodstream infections following transrectal prostate biopsy in South Sweden
  • 2022
  • In: BJU International. - : Wiley. - 1464-4096 .- 1464-410X. ; 130:4, s. 478-485
  • Journal article (peer-reviewed)abstract
    • ObjectiveTo report trends and characteristics of post-biopsy infections, with regard to etiology and resistance patterns, in a large unique cohort from a single-centre using the same antibiotic prophylactic regimens during a 15-year period.MethodsThis is an observational cross sectional cohort study, including all patients who underwent transrectal prostate biopsy (TR PBx) guided by ultrasound for the suspicion of prostate cancer at the Department of Urology, Skåne University Hospital between 1st May 2003 and 31st December 2017. Positive blood and urinary cultures were considered markers of bloodstream infection (BSI) and urinary tract infection (UTI), respectively. For all patients, details regarding blood or urine cultures from the date of the prostate biopsy and 14 days onwards were retrieved.ResultsIn total, 8,973 transrectal biopsy procedures were performed in 6,597 men during the study period. Over time, there was a trend towards a changing case-mix, with biopsy procedures increasingly being performed in older patients, patients with lower PSA values and higher prostate volume. During the study period, the number of biopsy procedures performed increased for each time period and we found an increasing rate of infectious complications in the last period. Overall, the rates of BSI and UTI with at least one relevant pathogen were 1 % (88/8,973) and 1.8% (159/8,973), respectively. In total, 16 of 90 strains (18%) were ESBL-producing, with an increasing proportion over time. The proportion of ciprofloxacin-resistant pathogens did not increase over time.ConclusionDuring the 15 years of this study, BSI and UTI after TR PBx increased. The rise of infectious complications post TR PBx in this population is unlikely to be explained by quinolone-resistance, as ciprofloxacin-resistance did not increase in the blood and urinary samples obtained during the study period. Future longitudinal studies are warranted to investigate why infectious complications after TR PBx are increasing.

  • Journal article (peer-reviewed)abstract
    • Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common condition that causes severe symptoms, bother, and quality-of-life impact in the 8.2% of men who are believed to be affected. Research suggests a complex pathophysiology underlying this syndrome that is mirrored by its heterogeneous clinical presentation. Management of patients diagnosed with CP/CPPS has always been a formidable task in clinical practice. Due to its enigmatic etiology, a plethora of clinical trials failed to identify an efficient monotherapy.

  • Role of hexaminolevulinate-guided fluorescence cystoscopy in bladder cancer: critical analysis of the latest data and European guidance
  • 2012
  • In: Scandinavian Journal of Urology and Nephrology. - : Informa UK Limited. - 0036-5599 .- 1651-2065. ; 46:2, s. 108-116
  • Journal article (peer-reviewed)abstract
    • Objective. Hexaminolevulinate (HAL) is an optical imaging agent used with fluorescence cystoscopy (FC) for the detection of non-muscle-invasive bladder cancer (NMIBC). Guidelines from the European Association of Urology (EAU) and a recent, more detailed European expert consensus statement agree that HAL-FC has a role in improving detection of NMIBC and provide recommendations on situations for its use. Since the publication of the EAU guidelines and the European consensus statement, new evidence on the efficacy of HAL-FC in reducing recurrence of NMIBC, compared with white light cystoscopy (WLC), have been published. Material and methods. To consider whether these new trials have an impact on the expert guidelines and on clinical practice (e. g. supporting existing recommendations or providing evidence for a change or expansion of practice), a group of bladder cancer experts from Denmark, Finland, Norway and Sweden met to address the following questions: What is the relevance of the new data on HAL-FC for clinical practice in managing NMIBC? What impact do the new data have on European guidelines? How could HAL-FC be used in clinical practice? and What further information on HAL-FC is required to optimize the management of NMIBC? Results and conclusions. This article reports the outcomes of the discussion at the Nordic expert panel meeting, concluding that, in line with European guidance, HAL-FC has an important role in the initial detection of NMIBC and for follow-up of patients to assess tumour recurrence after WLC. It provides practical advice, with an algorithm on the use of this diagnostic procedure for urologists managing NMIBC.

  • Genome-wide association study identifies 74 loci associated with educational attainment
  • 2016
  • In: Nature (London). - : Springer Science and Business Media LLC. - 1476-4687 .- 0028-0836. ; 533:7604, s. 539-542
  • Journal article (peer-reviewed)abstract
    • Educational attainment is strongly influenced by social and other environmental factors, but genetic factors are estimated to account for at least 20% of the variation across individuals. Here we report the results of a genome-wide association study (GWAS) for educational attainment that extends our earlier discovery sample of 101,069 individuals to 293,723 individuals, and a replication study in an independent sample of 111,349 individuals from the UK Biobank. We identify 74 genome-wide significant loci associated with the number of years of schooling completed. Single-nucleotide polymorphisms associated with educational attainment are disproportionately found in genomic regions regulating gene expression in the fetal brain. Candidate genes are preferentially expressed in neural tissue, especially during the prenatal period, and enriched for biological pathways involved in neural development. Our findings demonstrate that, even for a behavioural phenotype that is mostly environmentally determined, a well-powered GWAS identifies replicable associated genetic variants that suggest biologically relevant pathways. Because educational attainment is measured in large numbers of individuals, it will continue to be useful as a proxy phenotype in efforts to characterize the genetic influences of related phenotypes, including cognition and neuropsychiatric diseases.

  • Dose response of the 16p11.2 distal copy number variant on intracranial volume and basal ganglia
  • 2020
  • In: Molecular Psychiatry. - : Nature Publishing Group. - 1359-4184 .- 1476-5578. ; 25:3, s. 584-602
  • Journal article (peer-reviewed)abstract
    • Carriers of large recurrent copy number variants (CNVs) have a higher risk of developing neurodevelopmental disorders. The 16p11.2 distal CNV predisposes carriers to e.g., autism spectrum disorder and schizophrenia. We compared subcortical brain volumes of 12 16p11.2 distal deletion and 12 duplication carriers to 6882 non-carriers from the large-scale brain Magnetic Resonance Imaging collaboration, ENIGMA-CNV. After stringent CNV calling procedures, and standardized FreeSurfer image analysis, we found negative dose-response associations with copy number on intracranial volume and on regional caudate, pallidum and putamen volumes (β = −0.71 to −1.37; P < 0.0005). In an independent sample, consistent results were obtained, with significant effects in the pallidum (β = −0.95, P = 0.0042). The two data sets combined showed significant negative dose-response for the accumbens, caudate, pallidum, putamen and ICV (P = 0.0032, 8.9 × 10−6, 1.7 × 10−9, 3.5 × 10−12 and 1.0 × 10−4, respectively). Full scale IQ was lower in both deletion and duplication carriers compared to non-carriers. This is the first brain MRI study of the impact of the 16p11.2 distal CNV, and we demonstrate a specific effect on subcortical brain structures, suggesting a neuropathological pattern underlying the neurodevelopmental syndromes.

  • Catheter-associated urinary tract infections and other infections in patients hospitalized for acute stroke : A prospective cohort study of two different silicone catheters
  • 2016
  • In: Scandinavian journal of urology. - : Informa Healthcare. - 2168-1805 .- 2168-1813. ; 50:6, s. 483-488
  • Journal article (peer-reviewed)abstract
    • Objective: Catheter-associated urinary tract infection (CAUTI) is the most common healthcare-associated infection. The primary aim of this study was to investigate whether the use of a silicone catheter coated with an ultrathin layer of a combination of the noble metals gold, palladium and silver (BIPTM-silicone catheter) could reduce the incidence of CAUTI and antibiotic prescription compared with a standard silicone catheter in a cohort of acute neurological patients suffering primarily from stroke. At the same time, all infectious events requiring prescription of an antimicrobial agent were registered and are reported. Materials and methods: The study was designed as a crossover cohort study enrolling men and women aged over 18 years, requiring emergency management for stroke including the insertion of an indwelling catheter. Data on patient characteristics, urinary tract infections (UTIs), other infectious events and all antibiotic prescriptions were recorded prospectively. Results: The patients' characteristics differed in the two centres in terms of age but not in diagnosis distribution. UTIs were recorded in 78 (24.2%) of the patients, ahead of pulmonary tract infections (n = 65; 20.2%). There was no difference in terms of CAUTI in the two catheter groups, even in subgroups with catheter treatment for 1 week or less. The patients with a diagnosed UTI required 3.5 more days of hospitalization than those without a UTI. Conclusion: CAUTIs were the most frequent healthcare-associated infections, slightly ahead of pulmonary tract infections. No advantages of the coated catheter could be found in this cohort of critically ill patients.

  • 1q21.1 distal copy number variants are associated with cerebral and cognitive alterations in humans
  • 2021
  • In: Translational Psychiatry. - : Nature Publishing Group. - 2158-3188. ; 11:1
  • Journal article (peer-reviewed)abstract
    • Low-frequency 1q21.1 distal deletion and duplication copy number variant (CNV) carriers are predisposed to multiple neurodevelopmental disorders, including schizophrenia, autism and intellectual disability. Human carriers display a high prevalence of micro- and macrocephaly in deletion and duplication carriers, respectively. The underlying brain structural diversity remains largely unknown. We systematically called CNVs in 38 cohorts from the large-scale ENIGMA-CNV collaboration and the UK Biobank and identified 28 1q21.1 distal deletion and 22 duplication carriers and 37,088 non-carriers (48% male) derived from 15 distinct magnetic resonance imaging scanner sites. With standardized methods, we compared subcortical and cortical brain measures (all) and cognitive performance (UK Biobank only) between carrier groups also testing for mediation of brain structure on cognition. We identified positive dosage effects of copy number on intracranial volume (ICV) and total cortical surface area, with the largest effects in frontal and cingulate cortices, and negative dosage effects on caudate and hippocampal volumes. The carriers displayed distinct cognitive deficit profiles in cognitive tasks from the UK Biobank with intermediate decreases in duplication carriers and somewhat larger in deletion carriers-the latter potentially mediated by ICV or cortical surface area. These results shed light on pathobiological mechanisms of neurodevelopmental disorders, by demonstrating gene dose effect on specific brain structures and effect on cognitive function.

  • 2012
  • In: World Journal of Urology. - : Springer Science and Business Media LLC. - 1433-8726 .- 0724-4983. ; 30:1, s. 51-57
  • Journal article (peer-reviewed)abstract
    • Purpose Biofilm infections have a major role in implants or devices placed in the human body. As part of the endourological development, a great variety of foreign bodies have been designed, and with the increasing number of biomaterial devices used in urology, biofilm formation and device infection is an issue of growing importance. Methods A literature search was performed in the Medline database regarding biofilm formation and the role of biofilms in urogenital infections using the following items in different combinations: "biofilm," "urinary tract infection," "bacteriuria," "catheter," "stent," and "encrustation." The studies were graded using the Oxford Centre for Evidence-based Medicine classification. Results The authors present an update on the mechanism of biofilm formation in the urinary tract with special emphasis on the role of biofilms in lower and upper urinary tract infections, as well as on biofilm formation on foreign bodies, such as catheters, ureteral stents, stones, implants, and artificial urinary sphincters. The authors also summarize the different methods developed to prevent biofilm formation on urinary foreign bodies. Conclusions Several different approaches are being investigated for preventing biofilm formation, and some promising results have been obtained. However, an ideal method has not been developed. Future researches have to aim at identifying effective mechanisms for controlling biofilm formation and to develop antimicrobial agents effective against bacteria in biofilms.

  • Association of Copy Number Variation of the 15q11.2 BP1-BP2 Region With Cortical and Subcortical Morphology and Cognition
  • 2020
  • In: JAMA psychiatry. - : American Medical Association (AMA). - 2168-6238 .- 2168-622X. ; 77:4, s. 420-430
  • Journal article (peer-reviewed)abstract
    • Importance: Recurrent microdeletions and duplications in the genomic region 15q11.2 between breakpoints 1 (BP1) and 2 (BP2) are associated with neurodevelopmental disorders. These structural variants are present in 0.5% to 1.0% of the population, making 15q11.2 BP1-BP2 the site of the most prevalent known pathogenic copy number variation (CNV). It is unknown to what extent this CNV influences brain structure and affects cognitive abilities.Objective: To determine the association of the 15q11.2 BP1-BP2 deletion and duplication CNVs with cortical and subcortical brain morphology and cognitive task performance.Design, Setting, and Participants: In this genetic association study, T1-weighted brain magnetic resonance imaging were combined with genetic data from the ENIGMA-CNV consortium and the UK Biobank, with a replication cohort from Iceland. In total, 203 deletion carriers, 45 247 noncarriers, and 306 duplication carriers were included. Data were collected from August 2015 to April 2019, and data were analyzed from September 2018 to September 2019.Main Outcomes and Measures: The associations of the CNV with global and regional measures of surface area and cortical thickness as well as subcortical volumes were investigated, correcting for age, age2, sex, scanner, and intracranial volume. Additionally, measures of cognitive ability were analyzed in the full UK Biobank cohort.Results: Of 45 756 included individuals, the mean (SD) age was 55.8 (18.3) years, and 23 754 (51.9%) were female. Compared with noncarriers, deletion carriers had a lower surface area (Cohen d = -0.41; SE, 0.08; P = 4.9 × 10-8), thicker cortex (Cohen d = 0.36; SE, 0.07; P = 1.3 × 10-7), and a smaller nucleus accumbens (Cohen d = -0.27; SE, 0.07; P = 7.3 × 10-5). There was also a significant negative dose response on cortical thickness (β = -0.24; SE, 0.05; P = 6.8 × 10-7). Regional cortical analyses showed a localization of the effects to the frontal, cingulate, and parietal lobes. Further, cognitive ability was lower for deletion carriers compared with noncarriers on 5 of 7 tasks.Conclusions and Relevance: These findings, from the largest CNV neuroimaging study to date, provide evidence that 15q11.2 BP1-BP2 structural variation is associated with brain morphology and cognition, with deletion carriers being particularly affected. The pattern of results fits with known molecular functions of genes in the 15q11.2 BP1-BP2 region and suggests involvement of these genes in neuronal plasticity. These neurobiological effects likely contribute to the association of this CNV with neurodevelopmental disorders.

    • The aim of perioperative antibiotic prophylaxis is the prevention of surgical site infections and urinary tract infections during urological procedures. The indication for antibiotic prophylaxis comprises several risk factors such as the degree of contamination of the operative site, duration of surgery, implantation of devices and comorbidities of the individual patient. In general this involves a single antibiotic administration before the operative procedure. The antibiotic prophylaxis is part of the total antibiotic consumption and thus a factor contributing to emergence of antibiotic resistance. It is not a substitute for hygiene measures or operative precision.
