Dartos flap interposition in the surgical repair of rectourethral fistulas.

Abstract

Multilayer closures are important techniques in urethral fistula repair. We report our experience with dartos flap interposition in the repair of rectourethral fistula. A tip of a V-shaped scrotal skin flap is mobilized and de-epithelialized to develop a dartos flap. Two patients with a rectourethral fistula underwent fistula closure covered with this dartos flap. The surgical repair was successful in both cases and neither patient showed any late complication. A scrotal dartos flap is well vascularized and easy to mobilize. We believe this technique is helpful in preventing postoperative complications following complex posterior urethral surgery.
