Article Abstract
Introduction: This study investigates the intricate relationship between urodynamic findings and clinical symptoms in females with overactive bladder (OAB).
Methods: A retrospective cohort study, conducted at a tertiary university hospital, included female patients with positive detrusor overactivity (DO) OAB between November 2020 and November 2023. Patient demographics, OAB symptoms, and responses to anticholinergic treatment were recorded. Different Urodynamic features were analyzed.
Results: A total of 92 female patients with positive detrusor overactivity (DO) and overactive bladder (OAB) were included. The median age was 49 years (IQR: 30.75-61.75). Among them, 16 (17.4%) were diabetic, 18 (19.6%) had hypertension, and 69 (75%) were regular coffee drinkers. Over half of the participants, 56 (60.9%), were overweight (BMI 25-29.9). The prevalence of key symptoms included frequency in 54 (58.7%), urgency in 73 (79.3%), urgency incontinence in 33 (35.9%), and nocturia in 44 (47.8%). Frequency of urination was more common among non-diabetic patients (41/54, 75.9%; = 0.04), and urgency was significantly associated with non-smoking status (51/73, 69.9%; = 0.025). Most patients (84, 91.3%) had phasic DO, with a median maximum detrusor pressure (Pdet DO) of 30 cmHO (IQR: 20.0-53.0) and a median cystometric capacity of 385.5 mL (IQR: 296.25-443.75). Frequency was significantly associated with higher maximum Pdet DO pressure ( = 0.049). In terms of treatment response, 81 patients (88.0%) demonstrated a good response to anticholinergic therapy. Non-responders had significantly higher maximum Pdet DO pressure (median 59.0 cmHO, IQR: 30.0-66.0) compared to responders (median 30.0 cmHO, IQR: 19.5-47.0; = 0.013).
Conclusion: The amplitude of DO in female with idiopathic OAB is theoretically and clinically correlated to symptomatology and response to anticholinergic treatment.

Many patients with injuries to their central nervous system, especially those who have had a stroke or a spinal cord injury, have neurogenic voiding dysfunction. It happens when patients can't control their bladder voluntarily, which can make them feel urgency, experience leaks, or have trouble emptying their bladder. If not treated right away, it can cause infections, damage to the bladder, or even kidney problems over time.

Objectives: This study aims to examine the association of systemic immune-inflammation index (SII) and neutrophil-to-lymphocyte ratio (NLR) with the prevalence of overactive bladder (OAB).
Methods: This cross-sectional study analyzed data from 22,343 participants (≥ 20 years) in the National Health and Nutrition Examination Survey (2005-2018). We applied weighted multivariate logistic regression, restricted cubic spline (RCS) regression, subgroup, and sensitivity analyses to assess the associations between SII, NLR, and OAB.

Background: Overactive bladder (OAB) symptoms significantly affect the independence and quality of life in patient with multiple sclerosis (PwMS) by limiting daily activities. This study aimed to explore differences in fear of falling (FoF), gait, dual-task performance, and self-perceived impact of disease among PwMS with and without OAB.
Method: Participants were divided into two groups based on their Overactive Bladder Questionnaire (OAB-V8) scores: OAB (score ≥ 8) and non-OAB (score < 8).

The recent approval of a fixed-dose combination of silodosin (SOD) and solifenacin succinate (SOF) for overactive bladder syndrome has created a need for innovative analytical approaches enabling their simultaneous quantification. In this work, seven novel, eco-friendly, and cost-efficient spectrophotometric methods were developed for the concurrent determination of SOD and SOF. These methods overcome the limitations of conventional techniques by eliminating the need for complex instrumentation, labor-intensive procedures, and large volumes of hazardous organic solvents, offering a sustainable and accessible analytical alternative.

Objective: To demonstrate the impact of vibegron treatment in the phase 3 COURAGE trial (NCT03902080) on clinically meaningful response parameters in men with overactive bladder (OAB) receiving pharmacological therapy for benign prostatic hyperplasia (BPH) as measured by standard, validated patient-reported outcomes.
Methods: Men >45 years with OAB receiving pharmacotherapy for BPH were randomly assigned 1:1 to vibegron 75 mg or placebo for 24 weeks. Participants completed bladder diaries assessing changes in micturition frequency, nocturia, and urge urinary incontinence (UUI); International Prostate Symptom Score (IPSS); and OAB questionnaire (OAB-q).
