Bladder mucosal grafts for severe hypospadias: a successful technique.
Free grafts of bladder mucosa may be used to bridge long urethral defects in the repair of hypospadias. Strictures, which occur commonly at the proximal anastomotic site with the native meatus and where the bladder mucosa is exposed on the glans, have limited the use of the procedure. We have found that draining the proximal anastomosis prevents most strictures. When the distal most portion of the neourethra is formed from the skin of the ventral penile shaft and glans, no bladder mucosa is exposed and meatal stricture is thereby avoided.
