Vesicoureteral fistula is a well-known potential complication following bladder neck closure for neurogenic incontinence. Various maneuvers, including omental interposition, have been described to prevent this problem. Unfortunately omentum is not always available or feasible for use. We describe the surgical anatomy and use of a rectus abdominis muscle flap as an adjunctive maneuver during bladder neck closure to correct or prevent development of bladder neck fistula. We performed a retrospective chart review of all patients at our institution undergoing rectus abdominis muscle flap by a single surgeon (EAS). Patient demographics, indications for surgery, intraoperative and postoperative complications, and long-term efficacy were assessed. Cadaveric dissection was also performed to gain a greater understanding of the surgical anatomy relevant to this procedure. In 6 patients with neurogenic bladder dysfunction a rectus abdominis muscle flap was interposed between the bladder neck and urethral stump at bladder neck closure. There were no intraoperative or postoperative complications associated with this procedure. At a mean followup of 45.5 months (range 18 to 120) all 6 patients were continent of urine. There have been no urin...Continue Reading
