Duckett术式一期治疗尿道下裂的临床研究

目的:探讨横裁包皮带蒂岛状皮瓣尿道成形术(Duckett术)一期治疗尿道下裂的临床效果。方法:回顾性研究我科2003年～2007年采用Duckett术式一期修复尿道下裂患者20例,年龄2～22岁,平均11.3岁,其中阴茎体型3例,阴茎阴囊型17例;另外收集同期行膀胱粘膜代尿道术尿道下裂30例,年龄7～34岁,平均16.1岁,其中阴茎体型10例,阴茎阴囊型16例,会阴型2例,阴囊型2例。膀胱粘膜术全部行膀胱造瘘及留置尿道支架管,Duckett术仅留置尿道支架管。结果:Duckett术:1次手术成功17例(85%),术后尿瘘2例(10%),尿道狭窄1例(5%),2例尿瘘术后6个月修补成功,人均手术次数为1.1次;膀胱粘膜代尿道术:手术均分二期完成,手术成功26例(86.7%),术后尿瘘3例(10%),尿道狭窄1例(3.3%),再次手术修补瘘口治愈,人均手术次数为2.1次。2例尿道狭窄行尿道扩张后基本痊愈。结论:Duckett术一期修复尿道下裂效果良好,手术成功率与其他术式相近、术后并发症低,与膀胱粘膜尿道成形术相比,术后阴茎外观更满意,主要优点是一次完成手术。

Duckett's Procedure of One-Stage Urethroplasty for Hypospadias

Objective:To study the clinical effect of Duckett's procedure of one-stage urethroplasty with the transverse preputial island flap in the treatment of hypospadias. Methods: We retrospectively studied 20 cases of hypospadias treated by Duckett's procedure of one-stage urethroplasty with the transverse preputial island flap (Group A) from 2003 to 2007. The patients ranged in age from 2 to 22 years (mean 11.3 years). Another 30 hypospadias patients aged 7 to 34 (mean 16.1) years underwent urethroplasty with mu...
