Abstract
Rectourethral fistula is a rare complication of pelvic surgery, trauma, or inflammation. The many techniques for repairing these fistulas vary in their success rates. Our goal was to describe the use of a dartos muscle interposition flap for repair of these fistulas. We performed a retrospective review of eight patients who underwent repair of a rectourethral fistula with a dartos muscle interposition flap. We describe the success rate and patient-related factors that may have affected success. The technique of dartos muscle interposition is described and compared with other previously described techniques. Six of eight patients had healing of their fistulas documented by follow-up cystogram. Dartos muscle interposition is a straightforward technique that can result in successful fistula repair but should not be used in patients with risk factors for poor wound healing, such as an immunocompromised state or previous radiation therapy.
