Flaps in adult urethrocutaneous fistula repair: a report of two cases with the review of literature.

Urethrocutaneous fistula (UCF) poses a challenge to the reconstructive urologist in terms of its location, patient's expectations, availability of tissues for interposition, wound infection and chances of recurrence. Also, patient-related factors, such as uncontrolled diabetes, local surgery with extensive tissue loss, prior history of radiation, poor nutritional status and presence of any distal obstruction in the urethra severely affect the outcomes of a good repair with vascularised flap. We report two cases of UCF repair in adults using scrotal and gracilis muscle flaps (GMFs), their anatomic basis, technicality and advantages. The scrotal flap was used in the first case where it was freely available and GMF in second case where the patient had already undergone extensive local tissue debridement for Fournier's gangrene and hence, we had to look for a distant flap for protection of the UCF repair. Both patients had an uneventful recovery, there were no early or late treatment-related complications and follow-up after the third and sixth month of surgery revealed no recurrence and the patients are voiding well.
