- 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.

Tidskriftsartikel (refereegranskat)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.

Tidskriftsartikel (refereegranskat)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.

- 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.

- 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.

- Background: Infection is a serious adverse effect of prostate biopsy (P-Bx), and recent reports suggest an increasing incidence. Objective: The aim of this multinational multicentre study was to evaluate prospectively the incidence of infective complications after P-Bx and identify risk factors. Design, setting, and participants: The study was performed as an adjunct to the Global Prevalence Study of Infections in Urology (GPIU) during 2010 and 2011. Men undergoing P-Bx in participating centres during the 2-wk period commencing on the GPIU study census day were eligible. Outcome measurements and statistical analysis: Baseline data were collected and men were questioned regarding infective complications at 2 wk following their biopsy. The Fisher exact test, Student t test, Mann-Whitney U test, and multivariate regression analysis were used for data analysis. Results and limitations: A total of 702 men from 84 GPIU participating centres worldwide were included. Antibiotic prophylaxis was administered prior to biopsy in 98.2% of men predominantly using a fluoroquinolone (92.5%). Outcome data were available for 521 men (74%). Symptomatic urinary tract infection (UTI) was seen in 27 men (5.2%), which was febrile in 18 (3.5%) and required hospitalisation in 16 (3.1%). Multivariate analysis did not identify any patient subgroups at a significantly higher risk of infection after P-Bx. Causative organisms were isolated in 10 cases (37%) with 6 resistant to fluoroquinolones. The small sample size per participating site and in compared with other studies may have limited the conclusions from our study. Conclusions: Infective complications after transrectal P-Bx are important because of the associated patient morbidity. Despite antibiotic prophylaxis, 5% of men will experience an infective complication, but none of the possible factors we examined appeared to increase this risk. Our study confirms a high incidence of fluoroquinolone resistance in causative bacteria. (C) 2012 European Association of Urology. Published by Elsevier B.V. All rights reserved.
