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.
膀胱黏膜游离移植片可用于修复尿道下裂时桥接长段尿道缺损。狭窄常见于与原尿道口的近端吻合部位以及龟头处膀胱黏膜暴露的地方，这限制了该手术的应用。我们发现，引流近端吻合口可预防大多数狭窄。当新尿道的最远端部分由阴茎腹侧皮肤和龟头形成时，不会暴露膀胱黏膜，从而避免尿道口狭窄。
