INTRODUCTION: Urethrocutaneous fistula (UCF) complicating hypospadias surgery is associated with compromised tissue and perfusion at the UCF site, especially if recurrent. We report our technique for UCF repair. METHODS: Between 1997 and 2014, we treated 35 UCF in 26 postoperative hypospadias patients; 12 UCF were recurrent (mean 2.5; range 1-5). Mean age at UCF repair was 9.3 years (range 2-22). Our repair involves making a superficial incision 3-5 mm around the fistula orifice, placing multiple stay sutures in the outer edge of this incision and dissecting only the epidermis under traction for 7-10 mm. This technique does not compromise underlying connective tissue or tissue perfusion. The skin layer of the inner edge of the circumferential incision is trimmed completely and the fistula closed using 7/0 absorbable interrupted sutures. A pedicled external spermatic fascia, or tunica vaginalis flap is then mobilized to cover the repair site through a subcutaneous tunnel and the skin closed. A urethral catheter is placed and removed the next day. Duration of follow-up was calculated as the period from discharge home until the last outpatient clinic attendance. RESULTS: Repair was successful in all cases. Penile cosmesis was acceptable to good without any testicular complications or scrotal deformity. At mean follow-up of 7.4 years (range 0.4-17.3) there have been no recurrences. CONCLUSIONS: Our technique allows UCF to be repaired effectively and is also indicated for recurrences.
