  • Urovaginal fistula formation after gynaecological and obstetric surgical procedures: Clinical experiences in a Scandinavian series.
  • 2013
  • Ingår i: Scandinavian journal of urology and nephrology. - : Informa UK Limited. - 1651-2065 .- 2168-1805 .- 2168-1813. ; 47:2, s. 140-144
  • Tidskriftsartikel (refereegranskat)abstract
    • Abstract Objective. The aim of this retrospective study was to review what kinds of surgical procedures are most frequently complicated by urovaginal fistulae, to find out how they were diagnosed and managed, and to study the outcome after surgical reconstruction. Material and methods. Nineteen women who underwent fistula repair at Sahlgrenska University Hospital between 2003 and 2009 were retrospectively studied by reviewing the medical records. Results. For 17 of the 19 patients hysterectomy was the causative procedure. Fourteen patients developed vesicovaginal and five developed ureterovaginal fistula. Urethrocystoscopy was sufficient for the diagnosis in nearly 50% of the patients and when combined with methylene blue instillation 90% of all fistulae were found. Several patients sought medical advice due to vaginal leakage following gynaecological surgery without the doctor suspecting a fistula, and for these patients the diagnosis was delayed. Eighteen patients were operated on with an abdominal approach and one with a vaginal approach, in all cases a minimum of 3 months after primary surgery. The reconstruction technique included the interposition of vascularized tissue. None of the patients reported leakage or relapse at follow-up after fistula repair. Conclusions. Hysterectomy was the most common cause behind the formation of urovaginal fistulae. Misinterpretation of symptoms after gynaecological surgery was common even in cases where the symptoms were indicative of a urovaginal fistula. Delayed fistula repair after a minimum of 3 months, via the abdominal route and with the interposition of vascularized tissue, yielded an excellent final outcome.

  • Bladder pain syndrome/interstitial cystitis ESSIC type 3C : High expression of inducible nitric oxide synthase in inflammatory cells
  • 2013
  • Ingår i: Scandinavian journal of urology. - : Informa Healthcare. - 2168-1805 .- 2168-1813 .- 1651-2065. ; 47:1, s. 52-56
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. Bladder pain syndrome/interstitial cystitis (BPS/IC) includes a heterogeneous collection of underlying pathological conditions. Compared to the classic IC with a Hunner lesion, now denominated ESSIC type 3C, the non-Hunner type of BPS/IC appears different in a number of respects. In a previous study, measuring luminal nitric oxide (NO) in the bladder of patients with BPS/IC, it was reported that all patients with ESSIC type 3C had high levels of NO. The aim of the present study was to investigate the source of inducible nitric oxide synthase (iNOS) and thereby the cellular origin of NO production via iNOS. Material and methods. Immunohistochemistry, with two different anti-iNOS antibodies, was used to study10 patients with BPS/IC ESSIC type 3C who expressed high levels of intraluminal NO. These results were compared with four patients with non-Hunner BPS/IC. To substantiate further the involvement of iNOS in this condition, the protein expression of nitrotyrosine, a marker for iNOS activation, was also assessed. Results. On routine histopathology, the tissues of type 3C patients exhibited inflammatory infiltrates of varying intensity. Strong immunoreactivity for both iNOS and nitrotyrosine was noted within the urothelium but also within the inflammatory infiltrates in the lamina propria of these subjects. Conclusions. The findings of a clearly detectable protein expression of iNOS in both the urothelium and the inflammatory infiltrates in bladder biopsies from patients with BPS/IC ESSIC type 3C suggest that the production of NO, in this entity, may occur in different tissue compartments.

  • Population-based study on prognostic factors for recurrence and progression in primary stage T1 bladder tumours
  • 2013
  • Ingår i: Scandinavian Journal of Urology and Nephrology. - : Informa UK Limited. - 0036-5599 .- 1651-2065 .- 2168-1805 .- 2168-1813. ; 47:3, s. 188-195
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. Stage T1 urothelial carcinoma of the bladder (UCB) exhibits heterogeneous clinical behaviour, and the treatment is controversial. The aim of this study was to evaluate prognostic factors for UCB in a defined, population-based cohort comprising patients with a first time diagnosis of primary stage T1 UCB.Material and methods. The study population initially consisted of 285 patients with primary stage T1 UCB reported to the regional Bladder Cancer Registry in the Southeast Healthcare Region of Sweden from 1992 to 2001. The histological specimens were re-evaluated concerning stage, substaging of T1, World Health Organization (WHO) grade, lymphovascular invasion (LVI), tumour volume and total resected volume. Hospital records provided data on tumour size and multiplicity, occurrence of possible relapse and/or progression, death from UCB and whether treatment was given.Results. After re-evaluation, the study population comprised 211 patients. The median follow-up time was 60 months. LVI was a prognostic factor for UCB progression and recurrence. Tumour size larger than 30 mm and multiplicity increased the risk of recurrence. T1 substaging, tumour volume and total resected volume were not associated with recurrence or tumour progression.Conclusions. LVI is significantly correlated with progression and recurrence in patients with primary stage T1 UCB. Therefore, the presence of LVI should be evaluated in every new case of T1 UCB.

  • Influence of age and changes over time on erectile dysfunction: Results from two large cross-sectional surveys 11 years apart.
  • 2013
  • Ingår i: Scandinavian journal of urology and nephrology. - : Informa UK Limited. - 1651-2065 .- 2168-1805 .- 2168-1813. ; 47:3, s. 198-205
  • Tidskriftsartikel (refereegranskat)abstract
    • Abstract Objective.The aim was to explore how erectile dysfunction (ED) correlates with increasing age and a number of demographic, physical and lifestyle factors. Material and methods. A questionnaire was sent to a random sample (10 458) of men living in Gothenburg, Sweden, in 1992. The men were from the age cohorts 45, 50, 55 years, etc., up to the age of 85 or older. An analogous survey was sent to a random sample (10 845) of men of age cohorts 46, 51, 56 years, etc., in 2003. The prevalence of ED from the different age cohorts assessed on the two specific occasions 11 years apart was compared with a number of factors. Results.The response rates were 74.2% in 1992 and 68.7% in 2003. Within each survey the rate of ED increased with age at the same time as sexual activity decreased. This was paralleled by an increase in concomitant morbidity, intake of medications and alcohol consumption. The proportion of smokers and body mass index (BMI) decreased and the frequency of physical exercise increased until the age cohorts 70-71 years (1992) and 80-81 years (2003). Comparing the surveys, there was increased ED and decreased sexual activity over time despite an increase in exercise and decrease in smoking. In a multivariate analysis age, living alone, concomitant medication and smoking were the factors that significantly affected the risk of reporting ED. Conclusion. Despite a seemingly healthier lifestyle in 2003 compared with 1992, the rate of ED increased in the population, highlighting the importance of assessing lifestyle factors when examining ED patients.

  • Patient and tumour-related factors for prediction of urinary incontinence after radical prostatectomy.
  • 2012
  • Ingår i: Scandinavian Journal of Urology and Nephrology. - : Informa UK Limited. - 1651-2065 .- 0036-5599 .- 2168-1805 .- 2168-1813. ; epub ahead
  • Tidskriftsartikel (refereegranskat)abstract
    • Abstract Objective. The aim of this study was to identify preoperative patient and tumour-related factors associated with 12 months postoperative urinary incontinence. Material and methods. In total, 1529 men who had undergone radical prostatectomy for clinically localized prostate cancer between September 2008 and February 2010 at 15 Swedish hospitals completed a questionnaire before, 3 and 12 months after surgery. Urinary leakage, comorbidity and possible confounders were measured by self-administered validated questionnaires. Clinical data were collected preoperatively and postoperatively. The primary outcome, incontinence, was defined as the change of one pad or more per day. The ratio of proportions, estimated according to the log-binomial regression model, was analysed for 38 different factors and is presented as relative risks with 95% confidence intervals. Age-adjusted relative risk was calculated in the corresponding bivariate regression model. Results. Prospective data were available from 1360 men (response rate 89%). Results showed that age at surgery predicts long-term urinary incontinence exponentially. Patients reporting urinary leakage before prostate cancer diagnosis had an age-adjusted relative risk of 1.8 (95% confidence interval 1.3-2.4) for incontinence 12 months postoperatively. No statistically significant correlation was found between previous transurethral resection of the prostate, high body mass index or the other 34 evaluated factors and postoperative incontinence. Conclusions. Of 38 possible risk factors only age at surgery and preoperative urinary leakage were associated with 12 months postoperative incontinence in this study comprising 1360 men operated with radical prostatectomy. These findings may help the surgeon to have a targeted risk conversation with the patient before the treatment decision is made.

  • Management and outcome of muscle-invasive bladder cancer with clinical lymph node metastases. A nationwide population-based study in the bladder cancer data base Sweden (BladderBaSe)
  • 2019
  • Ingår i: Scandinavian journal of urology. - : Informa Healthcare. - 2168-1805 .- 2168-1813. ; 53:5, s. 332-338
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: To investigate the clinical management and outcome of patients with muscle-invasive bladder cancer with clinical lymph node involvement, using longitudinal nationwide population-based data.Methods: In the Bladder Cancer Data Base Sweden (BladderBaSe), treatment and survival in patients with urinary bladder cancer clinical stage T2-T4 N + M0 diagnosed between 1997 and 2014 was investigated. Patients´ characteristics were studied in relation to TNM classification, curative or palliative treatment, cancer-specific (CSS) and overall survival (OS). Age at diagnosis was categorised as ≤60, 61-70, 71-80 and >80 years, and time periods were stratified as follows: 1997-2001, 2002-2005, 2006-2010 and 2011-2014.Results: There were 786 patients (72% males) with a median age of 71 years (interquartile range = 64-79 years). The proportion of patients with high comorbidity increased over time. Despite similar low comorbidity, curative treatment was given to 44% and to 70% of those in older (>70 years) and younger age groups, respectively. Curative treatment decreased over time, but chemotherapy and cystectomy increased to 25% during the last time period. Patients with curative treatment had better survival compared to those with palliative treatment, both regarding CSS and OS in the whole cohort and in all age groups.Conclusions: The low proportion of older patients undergoing treatment with curative intent, despite no or limited comorbidity, indicates missed chances of treatment with curative intent. The reasons for an overall decrease in curative treatment over time need to be analysed and the challenge of coping with an increasing proportion of node-positive patients with clinically significant comorbidity needs to be met.

  • Stapled versus robot-sewn ileo-ileal anastomosis during robot-assisted radical cystectomy : a review of outcomes in urinary bladder cancer patients
  • 2021
  • Ingår i: Scandinavian journal of urology. - : Taylor & Francis. - 2168-1805 .- 2168-1813. ; 55:1, s. 41-45
  • Forskningsöversikt (refereegranskat)abstract
    • BackgroundWhereas the literature has demonstrated an acceptable safety profile of stapled anastomoses when compared to the hand-sewn alternative in open surgery, the choice of intestinal anastomosis using sutures or staples remains inadequately investigated in robotic surgery. The purpose of this study was to compare the surgical outcomes of both anastomotic techniques in robotic-assisted radical cystectomy.MethodsA retrospective analysis of patients with urinary bladder cancer undergoing cystectomy with urinary diversion and with ileo-ileal intestinal anastomosis at a single tertiary centre (2012–2018) was undertaken. The robotic operating time, hospital stay and GI complications were compared between the robotic-sewn (RS) and stapled anastomosis (SA) groups. The only difference between the groups was the anastomosis technique; the other technical steps during the operation were the same. Primary outcomes were GI complications; the secondary outcome was robotic operation time.ResultsThere were 155 patients, of which 112 (73%) were male. The median age was 71 years old. A surgical stapling device was used to create 66 (43%) separate anastomoses, while a robot-sewn method was employed in 89 (57%) anastomoses. There were no statistically significant differences in primary and secondary outcomes between RS and SA.ConclusionsCompared to stapled anastomosis, a robot-sewn ileo-ileal anastomosis may serve as an alternative and cost-saving approach.

  • A novel model of artificial intelligence based automated image analysis of CT urography to identify bladder cancer in patients investigated for macroscopic hematuria
  • 2024
  • Ingår i: Scandinavian journal of urology. - : Medical Journal Sweden AB. - 2168-1805 .- 2168-1813. ; 59, s. 90-97
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To evaluate whether artificial intelligence (AI) based automatic image analysis utilising convolutional neural networks (CNNs) can be used to evaluate computed tomography urography (CTU) for the presence of urinary bladder cancer (UBC) in patients with macroscopic hematuria. Methods: Our study included patients who had undergone evaluation for macroscopic hematuria. A CNN-based AI model was trained and validated on the CTUs included in the study on a dedicated research platform (Recomia.org). Sensitivity and specificity were calculated to assess the performance of the AI model. Cystoscopy findings were used as the reference method. Results: The training cohort comprised a total of 530 patients. Following the optimisation process, we developed the last version of our AI model. Subsequently, we utilised the model in the validation cohort which included an additional 400 patients (including 239 patients with UBC). The AI model had a sensitivity of 0.83 (95% confidence intervals [CI], 0.76-0.89), specificity of 0.76 (95% CI 0.67-0.84), and a negative predictive value (NPV) of 0.97 (95% CI 0.95-0.98). The majority of tumours in the false negative group (n = 24) were solitary (67%) and smaller than 1 cm (50%), with the majority of patients having cTaG1-2 (71%). Conclusions: We developed and tested an AI model for automatic image analysis of CTUs to detect UBC in patients with macroscopic hematuria. This model showed promising results with a high detection rate and excessive NPV. Further developments could lead to a decreased need for invasive investigations and prioritising patients with serious tumours.
