Bladder Neck Contracture Following Radical Retropubic versus Robotic-Assisted Laparoscopic Prostatectomy

Abstract

Introduction: Radical retropubic prostatectomy (RRP) and robotic-assisted laparoscopic prostatectomy (RALP) are co-standard surgical therapies for localized prostatic adenocarcinoma. These surgical modalities offer similar outcomes; however, lower rate of bladder neck contracture (BNC) is amongst the touted benefits of RALP. The differences between approaches are largely elucidated through multiple-surgeon comparisons, which can be biased by differential experience and practice patterns. We aimed to eliminate inter-surgeon bias through this single-surgeon comparison of BNC rates following RRP and RALP. Materials and Methods: We retrospectively reviewed all RRPs and RALPs performed by one surgeon over 4 years. We compared clinical characteristics, intraoperative and postoperative outcomes. Results: RRP patients had more advanced cancer and a higher biochemical recurrence rate. No significant differences were noted between groups in rates of anastomotic leakage, BNC, or 12-month postoperative pad-free continence. Conclusion: RRP offers similar outcomes to RALP with regard to postoperative urinary extravasation, urinary continence, and BNC.
