颊黏膜在修复尿道下裂应用中的探讨

目的：探讨尿道下裂中应用颊粘膜进行尿道重建的可行性。方法：从2008年2月～2009年4月,我们在Snodgrass尿道成形术基础上,通过将游离的自体颊黏膜瓣形成新尿道镶嵌于劈开的＂尿道板＂的方法对2例阴茎型尿道下裂病例进行手术治疗并评价其效果。结果：病例术后均无明显的尿道狭窄和尿瘘发生,无尿道憩室形成和尿道口黏膜增生外翻。结论：自体颊粘膜作为尿道替代材料用于尿道下裂分期成形术是可行的。

Investigation of the applications of buccal mucosal grafts in urethroplasty for hypospadias

Objective To study the applications of buccal mucosal grafts in urethroplasty for hypospadias. Methods From February 2008 to April 2009, two patients with penile type hypospadias underwent inlay buccal mucosal grafts on the found of Snodgrass urethroplasty in our hospital. They were followed up,Short and long complications in them were evaluated and analyzed. Results There were no urethra stricture or mucosal exstrophy, no fistula or urethrocele. Conclusions As the urethra substitute materials, autos buccal mucosat grafts proved to be feasible in urethroplasty for hypospadias by stages.
