STRATIFICATION OF POTENCY OUTCOMES FOLLOWING ROBOT-ASSISTED LAPAROSCOPIC RADICAL PROSTATECTOMY BASED ON AGE, PREOPERATIVE POTENCY AND NERVE SPARING (NS)

Introduction To identify factors affecting potency and to predict ideal patient subgroups who will have the highest chance of being potent post RALP based on NS. Materials and methods Analysis of 7268 patients that underwent RALP between 2008-2018 with a minimum of 12 months follow-up was performed. The patients were then categorized into 4 separate Neurovascular Bundle sparing groups (NVB 1-4). A Cox regression analysis was used to determine the independent factors predicting potency outcomes. Cumulative Incidence Functions (CIFs) were used to depict the probability and time to potency between the NS groups stratified by age and preoperative SHIM. Results Cox regression analysis of age, pre-operative SHIM score, and grades of NS significantly predicted potency outcomes post RALP. Patients with SHIM score ≥22 had a better chance of potency vs patients with SHIM
