Hypospadias repair by bladder mucosal graft: an initial report.
Surgical correction of major hypospadias defects is a challenging problem. Bladder mucosa has been reported as an excellent tissue for construction of a neourethra. We used bladder mucosa in 13 boys to create 15 neourethras when there was inadequate preputial skin to perform a vascularized pedicle flap or a free preputial graft. In 3 cases a bladder mucosa graft was used for initial repair of the hypospadias. All other boys had undergone prior hypospadias surgery. In 4 boys the initial result was satisfactory. Seven minor complications occurred in 5 boys, while 4 had more major complications. In 2 boys severe problems with stricture necessitated graft replacement and a satisfactory outcome has not been achieved. Our problems with stricture and stenosis seem to be related to the use of a subcutaneous tunnel for the graft bed and coring of the glans to create the meatus. Over-all, in 11 of the 13 boys the bladder mucosal graft provided an excellent resolution of the complex problem with easily managed postoperative complications.
