The Urachus: An Innovative Use as an Interposition Flap in Robotic-Assisted Prostatosymphyseal Fistula Repair

Clinical History: We have a 70-year-old male that presented with 2 L of chronic urinary retention, lower urinary tract symptoms, prostatomegaly, and large bladder diverticulae. He initially underwent greenlight laser photovapourization of the prostate and then a second-stage robotic bladder diverticulectomy. After this second procedure, he developed perineal pain with Enterococcus faecalis demonstrated on urine culture on postoperative day 7.
