Voiding and Erectile Function After Retroperitoneal Lymph Node Dissection for Testicular Cancer

This is a prospective observational study designed to evaluate the impact of retroperitoneal lymph node dissection (RPLND) on lower urinary tract and sexual function in patients treated for testicular cancer. The study incorporates validated patient-reported outcome measures (PROMs) alongside objective functional assessments to characterize post-RPLND urinary and sexual sequelae over time. Patients will complete standardized questionnaires preoperatively and at scheduled postoperative intervals, including the International Prostate Symptom Score (IPSS), International Consultation on Incontinence Questionnaire - Male Lower Urinary Tract Symptoms (ICIQ-MLUTS), International Index of Erectile Function (IIEF-5), Male Sexual Health Questionnaire - Ejaculatory Dysfunction (MSHQ-EjD), and EQ-5D-5L for health-related quality of life. Objective evaluation will include uroflowmetry and ultrasound-based measurement of post-void residual volume.
