Objectives: To evaluate the voiding repercussions of urethropexy.
Methods: We carried out a clinical and urodynamic study in 70 patients subjected to different techniques of urethropexy (Kelly, Raz, Marshall-Marchetti-Krantz, Burch and simplified Ramirez) for stress urinary incontinence. We evaluated the voiding repercussions of urethropexy.
Results: There was a significant increase in the obstructive symptoms with urethropexy (29% of the patients) although there was no relationship with the variation of the urinary flow rate. It also significantly diminished the urinary flow rate (85% of the patients) and increased the postvoiding volume significantly (3.68 times the average before surgery). The increase in postvoiding volume occurred more frequently in patients with diminished urinary flow rate before urethropexy (60% of the cases). The Raz technique showed less urodynamic data of voiding disturbances.
Conclusions: Urethropexy causes voiding disturbance. We believe the decrease in urinary flow rate is related to the increase in urethral resistance produced by urethropexy. In the cases with previously diminished urinary flow rate, reduction in bladder contractility is added to the former mechanism.

Sound-based uroflowmetry (SU) offers a non-invasive alternative to traditional uroflowmetry (UF) for evaluating lower urinary tract dysfunctions, enabling home-based testing and reducing the need for clinic visits. This study compares SU and UF in estimating urine flow rate and voided volume in 50 male volunteers (aged 18-60), with UF results from a Minze uroflowmeter as the reference standard. Audio signals recorded during voiding were segmented and machine learning algorithms (gradient boosting, random forest, and support vector machine) estimated flow parameters from three devices: Ultramic384k, Mi A1 smartphone, and Oppo smartwatch.

Introduction: Primary bladder neck obstruction (PBNO) is a rare but significant cause of BOO and LUTS in females, with unclear etiology involving theories of fibrotic narrowing, tissue hyperplasia, or muscle abnormalities. Due to nonspecific symptoms, PBNO diagnosis remains challenging, and optimal surgical treatment needs to be better defined.
Case Presentation: We report two cases of females in their 50s with recurrent urinary retention managed by indwelling catheters.

Objective: Information about congestive heart failure (CHF) treatment in the horse is limited. Torsemide, an oral loop diuretic, is increasingly used in humans, dogs, and cats with CHF. Torsemide is well absorbed and induces diuresis in healthy horses, and its use in a horse with CHF has been reported.

Objectives: To evaluate urinalysis parameters useful for identifying mixed cultures in urine culture using an automated urinary particle analyzer to assess quality indicators (QIs) for urine sample contamination.
Methods: A retrospective observational cross-sectional study was conducted with 2,527 urine samples from patients of a quaternary hospital in Brazil. Urine samples were processed simultaneously in Sysmex UF-5000 flow cytometry analyzer (urinalysis) and MALDI-TOF (culture).

Introduction: Water Jet Ablation Therapy (WJAT) and Holmium Laser Enucleation of the Prostate (HoLEP) represent two common surgical treatments for Benign Prostatic Hyperplasia (BPH). Despite their increasing use, there is no study between these two methods. We aim to evaluate their efficacy and safety through a network meta-analysis (NMA), providing critical insights for clinical decision-making in the management of moderate to severe lower urinary tract symptoms (LUTS) due to BPH.
