Surgical anatomy of accessory pudendal arteries in Japanese men: preservation techniques for robot-assisted radical prostatectomy.

ABSTRACT:

Objective

This study aimed to investigate the anatomy of the accessory pudendal artery (APA) in Asian men and to describe APA preservation techniques during robot-assisted radical prostatectomy (RARP).

Methods

APA was defined as "any artery located in the periprostatic region running parallel to the dorsal vascular complex and extending caudally toward the anterior perineum". The anatomical variations of the APA were reviewed in 589 consecutive Japanese men who underwent conventional RARP at our institution between April 2019 and November 2023, including the number, laterality, side, size, and local distribution (apical vs. lateral). The apical APA emerges near the prostatic apical region, whereas the lateral APA courses along the lateral aspect of the prostate. They
