Abstract
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.
