摘要: [摘要] 目的 探讨改良加盖岛状皮瓣( Onlayislandflap 法)尿道成形术在小儿尿道裂手术中的应用经验。方
法 回顾性分析应用改良 Onlayislandflap 术式治疗尿道下裂患儿 76 例。 Onlayislandflap 术式改良方法:包皮脱
套后自阴茎海绵体上游离尿道板/尿道海绵体,利用其弹性矫正下弯;尽可能选用包皮内板作为岛状皮瓣与尿道板
U 形吻合。结果 全组 76 例中成功保留尿道板 73 例( 96. 0% ),阴茎伸直良好。包括行包皮脱套及阴茎腹侧肉膜松
解后阴茎伸直的患儿 4 例,经游离尿道板/尿道后成功矫正下弯 58 例,加行背侧海绵体折叠 11 例(其中包皮退套、
腹侧肉膜松解后残余阴茎下弯 <30° 者 4 例,残余阴茎下弯 >30° 者 7 例)。手术成功率 88.
2% ( 67 / 76 例)。尿道瘘
5 例(其中经手术修补 4 例,自行闭合 1 例);尿道外口狭窄 1 例,行尿道扩张后痊愈。未发现尿道憩室、坏死、切口
裂开等情况。结论 采用游离尿道板/尿道海绵体矫正下弯、包皮内板作为岛状皮瓣的 Onlay 尿道成形术能明显增
大该术式适应证,提高手术成功率,减少术后并发症,值得临床推广。
