Nerve-sparing techniques in robot-assisted radical prostatectomy - anatomical approach.

Introduction: Nerve-sparing (NS) techniques in robot-assisted radical prostatectomy (RARP) are foundational to preserving sexual function and urinary continence in prostate cancer (PCa) patients.

Areas covered: This article aims to classify nerve-sparing (NS) techniques in RARP based on an anatomical approach to the prostate. We have identified three main NS approaches in RARP: anterior, lateral, and posterior. The anterior approach, which involves early retrograde nerve release, improves early potency rates. The lateral approach, using hybrid techniques and extra-fascial dissection, provides clear nerve visualization and reduces nerve injuries, enhancing continence and potency recovery. The posterior approach, particularly the hood technique, effectively preserves periurethral structures, leading to high continence rates within a year post-surgery. The posterior approach effectively balances nerve preservation with cancer control.

Expert opinion: Re-classifying NS techniques in RARP based on an anatomical approach optimizes patient outcomes and the surgeon choice. A personalized approach to those techniques improves functional recovery and maintains oncological safety in PCa surgery. Further studies are needed to confirm those findings and refine the selection criteria.
