The urinary tract reconstruction in a robot-assisted surgery for rectal malignancy with combined prostate and seminal vesicle resection

Asian J Endosc Surg. 2024 Oct;17(4):e13375. doi: 10.1111/ases.13375.

Abstract

Introduction: In certain cases of rectal malignancy in which invasion is confined to the prostate and/or seminal vesicles, bladder-sparing surgery may be chosen instead of total pelvic exenteration. However, even if the bladder is preserved, postoperative urinary dysfunction and vesicourethral anastomotic leakage are concern.

Materials and surgical technique: We employ various techniques based on robot-assisted radical prostatectomy for reconstructing the urinary tract. These techniques include advanced reconstruction of vesicourethral support, total anatomical reconstruction, and a method called anterior reconstruction. In addition, suture fixation of bladder to the anterior abdominal wall, and re-approximation of bladder by peritoneal suture were done.

Discussion: Reliable robot-assisted vesicourethral anastomosis and reinforcement of the anastomotic wall could potentially enhance the self-voiding rate and decrease the risk of anastomotic failure.

Keywords: prostatectomy; rectum neoplasm; robot‐assisted surgery.
