To investigate how urological studies using composite endpoints as the primary outcome were cited. In this quality analysis of citations, three randomized clinical trials each investigating oncological and non-oncological urology were selected for citation analysis based on pre-defined criteria. In total, 531 papers citing the selected studies were reviewed; citations were evaluated based on whether they correctly referred to the composite endpoint and if singleton endpoints were defined and/or discussed. Among the citations, 223/531 (42%) referred to the composite endpoint, of which 217/223 (97.3%) correctly cited the composite endpoint. However, only 91/217 (41.9%) defined and/or discussed the singleton endpoints of the composite endpoint. The lack of a validated instrument for citation analysis was a limitation of this study. Meanwhile, the main strength is the large number of individually analyzed citations. The composite endpoints of urological randomized clinical trials are generally cited without referring to the composite endpoint; when cited, the composite endpoints are described correctly. However, in most cases, without defining or discussing the singleton endpoints. [ABSTRACT FROM AUTHOR]

Objective: This paper aims to estimate the incidence of post-obstructive diuresis (POD) among patients with urinary retention, explore possible underlying causes and identify patients who need hospitalization. Material and methods: This retrospective study includes patients admitted for urinary retention in Zealand University Hospital, Denmark. We collected demographic characteristics, health information and laboratory results from patients' charts and analyzed data statistically. Results: We assessed 64 patients, and POD occurred in 29.7%. A significant correlation was observed between POD and residual urine, serum creatinine, serum urea and systolic and diastolic blood pressure. We identified increased residual urine volume as an independent predictor of POD by OR 1.21 (95% CI: 1.06–1.40), p = 0.006 per 100 mL and creatinine of >120 umol/L is an independent predictor of POD by OR 7.17 (95% CI; 1.63–31.37), p = 0.009. Patients with residual urine at the time of diagnosis of more than 1150 ml will suffer POD with a probability of area under curve (AUC) 0.874 (p < 0.001) with 84% sensitivity and 78% specificity. Patients with creatinine >120 umol/L will suffer POD with a probability of AUC 0.774 (p < 0.001) with 68% sensitivity and 82% specificity. Conclusion: In this small retrospective study residual urine of more than 1150 mL and elevated creatinine are independent predictors of POD in patients with urinary retention. However, larger prospective studies are needed to confirm these findings. [ABSTRACT FROM AUTHOR]

Background: Urethral stricture disease (USD) represents a complex urological problem. Urethroplasty is considered the gold standard for the treatment of USD. Most available studies report outcome data obtained from retrograde urethrography and uroflowmetry. Only a limited number of papers describe the effect of urethroplasty on erectile function and their results are inconsistent. The goal of this prospective study was to evaluate the effect of urethroplasty on both lower urinary tract and erectile function using objective parameters and standardized patient-reported outcome measurement tools. Materials and Methods: A total of 55 consecutive patients with USD were enrolled into the study. Patients underwent ventral onlay urethroplasty, urethroplasty according to the Asopa technique, dorsal onlay urethroplasty, cutaneous flap urethroplasty using the Orandi technique or anastomotic repair. All patients were evaluated using uroflowmetry, urethrography, the PROM-USS questionnaire and the International Index of Erectile Function-5 questionnaire (IIEF-5) pre-operatively and consequently post-op, in 3-month intervals. This study presents the comparison of baseline pre-op parameters and parameters 12 months after the surgery using the Wilcoxon signed rank test, Wilcoxon rank sum test and the Kruskal-Wallis one-way analysis of variance. Results: A significant improvement in uroflowmetry parameters, all domains of the PROM-USS questionnaire, as well as the overall score of the IIEF-5 was observed. No statistically significant differences between sub-groups were found when comparing treatment results in patients with short versus long strictures and patients with penile urethra stricture versus bulbar or membranous urethra stricture. Conclusions: Urethroplasty yielded very good functional results with respect to both lower urinary tract and erectile functions. [ABSTRACT FROM AUTHOR]

Dear Editor, We read with great interest the paper by Banerjee on 50 years' experience of clean intermittent self-catheterization (CISC) [[1]]. Further technical development has later provided female catheters, foldable catheters, and ready-to-use catheters for travelling purposes [[7]] as well as PVC-free catheters developed to reduce environmental impact [[8]]. Various bladder outlet disorders, underactive detrusor, neurogenic and non-neurogenic incontinence as well as voiding complications after bowel surgery or gynaecological procedures are often managed by CISC for longer or shorter periods of time.
