Objective: The purpose of this pilot study was to compare the efficacy of 2 techniques for evaluating bladder function after transvaginal surgery.
Study Design: Subjects scheduled for transvaginal, outpatient surgery were consecutively enrolled and randomized to backfill-assisted voiding trial or a trial of spontaneous voiding after surgery.
Results: Sixty subjects were enrolled. The mean time in the perioperative anesthesia care unit for the backfill group was 199.5 minutes vs 226.6 minutes in the spontaneous voiding group (P = .08). Subjects randomized to backfill were more likely to adequately empty their bladders and be discharged home without catheter drainage than subjects in the spontaneous voiding group (61.5% vs 32.1%, respectively, P = .02). Multiple logistic regression further demonstrated that the backfill-assisted technique predicted successful bladder emptying after vaginal surgery (P = .02).
Conclusion: Women undergoing transvaginal outpatient surgery are more likely to empty their bladder effectively before discharge if they are evaluated with a backfill-assisted voiding trial.

Impact of clean intermittent self-catheterization and indwelling catheterization on perioperative outcomes in patients with urinary retention undergoing BPH surgery: A comparative monocentric retrospective study.
Fr J Urol

Department of Urology, Bordeaux Pellegrin University Hospital, Bordeaux, France.
Introduction And Objectives: In case of acute urinary retention (AUR) due to benign prostatic hyperplasia (BPH) first trial without catheter (TWOC) may fail in about 30% of cases. In this situation most of patients have to keep an indwelling catheter (IDC) or to perform clean intermittent self-catheterization (CISC) until surgery. Although CISC has shown several advantages over IDC in neurologic patients, it is barely proposed in case of acute or chronic urinary retention due to BPH and comparative data on the outcomes of BPH surgery are very sparse.

Article Synopsis
- * The study analyzed data from 98 patients at Kyoto Katsura Hospital, discovering that age, cognitive function upon admission, and high residual urine levels were key factors influencing whether patients needed their catheters reinserted.
- * Results showed that nearly half of the patients could urinate independently by discharge, with overall improvements in motor and functional scores, but cognitive scores did not significantly change.
Comparison of the 3-Year Continuation Rate and Discontinuation Factors Between Vibegron and Mirabegron in Patients With Overactive Bladder: A Retrospective Follow-Up Study in a Rehabilitation Hospital in Japan.

Department of Urology, Hyogo Prefectural Central Rehabilitation Hospital, Kobe, Hyogo, Japan.
Objectives: The objective of this study is to compare the 3-year continuation rate and discontinuation factors between vibegron and mirabegron in patients with overactive bladder in a rehabilitation hospital in Japan.
Methods: The 3-year continuation rate of the target drugs and reasons for discontinuation as well as patients' backgrounds and adverse effects were evaluated retrospectively from the medical records between September 2018 and December 2020. After selecting patients according to our inclusion and exclusion criteria, 136 cases taking mirabegron and 82 taking vibegron were adjusted for intergroup variability by propensity score matching.
Effects of Exercise on Urinary Parameters and Proteins in Well-Trained Canicross Dogs: A Preliminary Study.

Department of Veterinary Medical Sciences, Alma Mater Studiorum-University of Bologna, Via Tolara di Sopra 50, Ozzano dell'Emilia, 40064 Bologna, Italy.
The aim of the present study was to investigate the effects of exercise during canicross competition on urinary biochemical parameters and urinary proteins. Our results showed that, among the parameters analysed in routine urinalysis, pH was affected by exercise and albuminuria also showed changes immediately after physical exercise with a return to baseline within 2 h after the physical activity. In particular, SDS-PAGE electrophoresis allowed the separation of the urinary proteins on the basis of their molecular mass allowing a qualitative evaluation of the urinary proteome and a quantitative analysis of urine albumin and uromodulin, with a significant increase in urinary albumin and a decrease in uromodulin after exercise.

Article Synopsis
- The study assessed the feasibility and outcomes of I-LEVUR, a surgical technique for treating upper moiety ectopic ureter in patients with a duplex renal system, which avoids reimplanting the lower ureter.
- Twelve patients, mostly young children, underwent the procedure with a mean surgical time of 127.5 minutes, and no major complications were reported post-surgery.
- Results indicated improved urinary continence in all patients after an average follow-up of about 78.5 months, suggesting that I-LEVUR is a safe and effective option that preserves normal ureter function.
