Objectives: To describe a technique for repairing urethral diverticula which includes neourethral reconstruction and increasing the mechanical support of the neourethra.
Patients and methods: Between February 1995 and May 2000, 267 patients with proximal hypospadias underwent a one-stage penile skin longitudinal flap urethroplasty. The overall postoperative complication rate was 20%; a diverticulum formed in 24 patients (9%) and in all it was repaired. Diverticulectomy was carried out by de-epithelialization of excess diverticular skin, so that two subcutaneous vascularized tissue wings could be created. After re-establishing distal urethral patency and neourethral closure, the de-epithelialized diverticular wings were folded and overlapped to form a mechanical support for the neourethral ventral wall; this procedure was termed 'pseudospongioplasty'.
Results: There were no recurrences of diverticulum or any fistula formation. The only complication was urethral stenosis in two cases, which was successfully resolved by internal urethrotomy.
Conclusion: Re-establishing patency and providing mechanical support are essential when repairing a urethral diverticulum. Our technique with pseudospongiosal tissue reconstruction during the repair represents a good alternative or addition to other techniques.
