摘要
目的探讨复杂尿道下裂的治疗以及术后尿道狭窄的预防。方法从2005年5月至2005年10月,我们在Snodgrass尿道成形术基础上,通过将游离的自体唇黏膜瓣镶嵌于劈开的“尿道板”再卷管形成新尿道的方法对23例经过至少1次手术的复杂尿道下裂病例进行再次手术治疗并评价其效果。结果所有病例术后均无明显的尿道狭窄,尿瘘发生率17.4%(4/23)。无尿道憩室形成和尿道口黏膜增生外翻。结论镶嵌式唇黏膜尿道成形术兼有Snodgrass尿道成形术和游离移植物代尿道成形术的优点,是治疗尿道下裂合并尿道狭窄的有效方法;对于尿道板发育不良或经阴茎伸直术后的重度尿道下裂病例,镶嵌唇黏膜具有预防尿道狭窄的作用。
Objective To introduce a modified technique of inlay oral mucosal graft with Snodgrass urethroplasty for complicated hypospadias and to explore the role of this technique in the prevention of urethrostenosis after surgery. Methods From May 2005 to October 2005, 23 cases with complicated hypospadias underwent free oral mucosal graft with Snodgrass urethroplasty in this institute. All patients were followed up. Short and long-term complications in these patients were recorded and analyzed. Results There was no urethra stricture or mucosa exstrophy at meatus. Fistula developed in 4 of 23 （17. 4%） cases. Conclusions Inlay oral mucosal graft with Snodgrass urethroplasty for the complicated hypospadias can get good results with low incidence of urethrostenosis because it combines the advantages of both Snodgrass technique and free graft technique.
