Abstract

Various neurovascular bundle-sparing techniques have been introduced to maximize recovery of erectile function after robot-assisted radical prostatectomy (RARP). The clipless intrafascial neurovascular bundle-sparing technique aims to preserve periprostatic structures and neurovascular bundles as much as possible by avoiding clipping of the vascular pedicles. This study reports 1-year functional and oncologic outcomes and postoperative complications in 105 patients with intact preoperative erectile function who underwent a modified clipless intrafascial neurovascular bundle-sparing RARP. Intact erectile function was defined as score ≥ 21 on the Sexual Health Inventory for Men questionnaire or ability to have sexual intercourse. Median follow-up was 26.5 months (IQR 15.25–48). Postoperative erectile function recovery rates were 71.4%, 81.9%, 88.6%, 92.4%, and 94.3% at 1, 3, 6, 9, and 12 months, respectively. The rate of positive surgical margins was 16.2% overall and 11.8% in patients with stage pT2 disease. The biochemical recurrence rate was 6.7% overall. The modified clipless intrafascial neurovascular bundle-sparing technique is safe and feasible and can achieve excellent recovery of erectile function after RARP. Further large-scale prospective comparative studies are warranted.
