Abstract
We report a multicenter experience using double dartos flap to protect the neourethra in TIP urethroplasty for distal and midpenile hypospadias. A total of 394 patients underwent tubularized incised plate urethroplasty for primary distal and midpenile hypospadias using double dartos flap protection by ten pediatric surgeons and urologists at five different institutions. Tubularized incised plate urethroplasty protected by a double dartos flap was simple to perform and flaps were easy to obtain. Complications occurred in 23 patients (5.83%): fistulas 1.01% (4 cases), stenosis 0.25% (1 case), mild stenosis 2.53% (10 cases), dehiscence of ventral cutis 0.50% (2 cases) and penile torsion 1.26% (5 cases). All fistulae had a spontaneous resolution. Double dartos flap to protect tubularized incised plate urethroplasty is safe with a low complication rate. The neourethra is covered entirely with a double layer of vascularized tissue and the double coverage appears a good choice for preventing urethrocutaneous fistula formation.
