Urologic use of gracilis muscle flap for nonhealing perineal wounds and fistulas.

A chronic sinus or urinary fistula in the perineum secondary to surgery and/or radiation therapy for pelvic malignancy may cause serious morbidity and be difficult to treat. The gracilis muscle, either by itself or as a myocutaneous flap, has excellent properties for aiding in healing. Over a six-year period, three nonhealing perineal wounds and three urinary fistulas have healed after the gracilis muscle flap procedure.
