The predictive value of prostate spherical volume ratio in lower urinary tract symptoms and clinical progression of benign prostatic hyperplasia: a retrospective cohort study.
Int Urol Nephrol
January 2025
Department of Urology, School of Medicine, Shanghai East Hospital, Tongji University, No. 150 Jimo Road, Pudong New District, Shanghai, 200120, China.
Purpose: To evaluate the predictive value of Prostate Spherical Volume Ratio for Lower urinary tract symptoms and clinical progression of Benign prostatic hyperplasia. And compared with other prostatic anatomical parameters.
Methods: A total of 154 patients with Benign prostatic hyperplasia who underwent MRI and urodynamics were included in the study, while prostate anatomical parameters such as prostate spherical volume ratio, prostate volume, intravesical prostatic protrusion, prostatic urethral length and presumed circle area ratio were determined based on MRI measurements.
Exploring the characteristics of detrusor after contraction in females with pure urodynamic stress incontinence.
BMC Urol
January 2025
Department of Urology and Institute of Urology, West China Hospital, Sichuan University, No. 37 Guo Xue Xiang, Chengdu, Sichuan, 610041, People's Republic of China.
Purpose: This study aims to evaluate detrusor after contraction (DAC) characteristics in females with pure urodynamic stress incontinence (USI).
Methods: We examined the urodynamics database from our urodynamic study center. Urodynamic data from pure USI cases with and without DAC were compared.
[Neurological diagnosis of lower urinary tract dysfunction].
Urologie
January 2025
KontinenzZentrum AG Zürich, Witellikerstrasse 40, 8032, Zürich, Schweiz.
Background: Neurophysiological investigations are infrequently utilized in the diagnostic workup of lower urinary tract symptoms (LUTS).
Objective: To determine the potential contributions of neurophysiological assessments in the diagnostic process of LUTS and their integration into systemic neurological and psychosomatic disorders.
Materials And Methods: This study elucidates the role of neurophysiological tests specific to pelvic floor diagnostics, namely pudendal nerve somatosensory-evoked potentials (SEP) and external anal sphincter electromyography (EMG), through the presentation of two clinical case reports.
Deep Learning and Numerical Analysis for Bladder Outflow Obstruction and Detrusor Underactivity Diagnosis in Men: A Novel Urodynamic Evaluation Scheme.
Neurourol Urodyn
January 2025
Department of Urology, Renmin Hospital of Wuhan University, Wuhan, China.
Objectives: To automatically identify and diagnose bladder outflow obstruction (BOO) and detrusor underactivity (DUA) in male patients with lower urinary tract symptoms through urodynamics exam.
Patients And Methods: We performed a retrospective review of 1949 male patients who underwent a urodynamic study at two institutions. Deep Convolutional Neural Networks scheme combined with a short-time Fourier transform algorithm was trained to perform an accurate diagnosis of BOO and DUA, utilizing five-channel urodynamic data (consisting of uroflowmetry, urine volume, intravesical pressure, abdominal pressure, and detrusor pressure).
Increased Afferent Nerve Firing Is Correlated With the Detection of Bladder Wall Micromotion in a Perfused Ex-Vivo Porcine Model.

Introduction And Objective: Observable autonomous rhythmic changes in intravesical pressure, termed bladder wall micromotion, is a phenomenon that has been linked to urinary urgency, the key symptom in overactive bladder (OAB). However, the mechanism through which micromotion drives urinary urgency is poorly understood. In addition, micromotion is inherently difficult to study in human urodynamics due to challenges distinguishing it from normal cyclic physiologic processes such as pulse rate, breathing, rectal contractions, and ureteral jetting.
