Modified Snodgrass tubularized incised plate urethroplasty prevents fistula formation in hypospadias.

Urethrocutaneous fistula is a common complication after redo urethroplasty for hypospadias, or urethroplasty for patients with thin urethral plate. We modified Snodgrass' tubularized incised plate urethroplasty (STIPU) by stripping the most superficial skin from both sides of the U-shaped incision to expose more subcutaneous tissue along the suture line. Our modified STIPU would appear to be effective in preventing postoperative urethrocutaneous fistula formation in redo urethroplasty for hypospadias, and urethroplasty for patients with thin urethral plate.
