Erectile Dysfunction (ED) Clinical Trials

This prospective randomized controlled study aims to evaluate the effect of mobile-based perioperative education on postoperative urinary incontinence and erectile function in patients undergoing radical prostatectomy. Patients scheduled for radical prostatectomy will be assigned to either an intervention group or a control group. The intervention group will receive standard care plus a structured mobile application-based perioperative education program including video-assisted pelvic floor muscle training, perioperative education modules, reminders, and follow-up components. The control group will receive routine perioperative care and standard patient education. Data will be collected preoperatively, after urinary catheter removal, and at 1 month and 3 months after surgery. The primary outcomes are urinary incontinence and erectile function, assessed using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), the International Index of Erectile Function-5 (IIEF-5), and a 24-hour pad assessment. Secondary outcomes include lower urinary tract symptoms and disease-specific quality of life assessed by the International Prostate Symptom Score (IPSS), psychological status assessed by the Depression Anxiety Stress Scale-21 (DASS-21), and system usability assessed by the Turkish version of the Computer System Usability Questionnaire-Short Version (T-CSUQ-SV)
