Transabdominal Robot-Assisted Laparoscopic Urethral Diverticulectomy of a Complex Anterior Horseshoe Diverticulum of the Proximal Urethra.

Complex, proximal, anteriorly located urethral diverticula present the reconstructive urologist with a uniquely challenging task for repair through a conventional transvaginal approach. Herein, we present the first report of urethral diverticulectomy to excise a large, anterior, horseshoe-shaped urethral diverticulum that resulted in bladder outlet obstruction, using a transabdominal robot-assisted laparoscopic approach.
