Efficacy and Reliability of Mobile Uroflowmetry in Patients With Benign Prostatic Hyperplasia Undergoing Transurethral Resection: Prospective Multicenter Observational Pilot Validation Study
Abstract
Background Accurate assessment of voiding patterns before and after surgery for lower urinary tract symptoms is critical in patient care, but it places heavy burdens on both the patient and the clinic. While methods for telemedicine have been devised, no technology for acoustic assessment of urinary patterns has been prospectively evaluated for clinical use. Objective This study aims to assess the precision of a mobile app–based uroflowmetry and compare it with in-office uroflowmetry measurements for the management of patients undergoing surgical treatment for benign prostatic hyperplasia (BPH). Methods This study was designed as a prospective, multicenter, observational pilot validation study conducted at 3 tertiary centers. A total of 46 patients with BPH who had not received any previous treatment within 4 weeks of their initial outpatient clinic visit were prospectively enrolled. After diagnosis, participants with BPH conducted subsequent uroflowmetry measurements by using a sound-based mobile app, proudP, for at least 4 days during the pretreatment period, followed by transurethral resection of prostate (TURP). Additional measurements were taken at the preoperative visit and 4-day periods after 2, 6, and 12 weeks of treatment initiation, with concurrent in-office measurements. Uroflowmetry parameters, including maximum flow rate (Qmax) and voided volume, were compared. Patient satisfaction was evaluated using a scale ranging from 0 to 10 at the end of the 12-week study.…
