改良Snodgrass术治疗尿道下裂疗效观察

Effect Observation of Improved Snodgrass Operation for Hypospadias

目的:评价尿道板纵切卷管尿道成形术(Snodgrass术)治疗尿道下裂的疗效。方法:回顾性分析2005年1月～2008年12月间31例行改良Snodgrass术的尿道下裂患者临床资料:患者年龄2～18岁,平均7.2岁,其中阴茎头型尿道下裂11例,阴茎体型尿道下裂18例,阴囊型尿道下裂2例。结果:一次手术治愈29例(93.55%);1例(3.22%)发生尿道狭窄,经尿道扩张治愈;1例(3.22%)发生尿瘘,术后6个月再次行改良Snodgrass术治愈。结论:改良Snodgrass术保留了尿道板,操作简单,手术时间短,并发症较少,手术成形效果好,对于首次手术失败后再次尿道成形效果良好,是适用于各型尿道下裂治疗的较好方法。

Objective：To evaluate the effect of improved Snodgrass operation of hypospadias repair. Methods： From January 2005 to December 2008, 31 patients with hypospadias underwent improved Snodgrass operation. Their ages ranged from 2 to 18 years with a mean of 7.2 years. The type of hypospadias were glans （n=11）, penile shaft （n= 18） and scrotal （n=2） respectively. Results：29 cases were cured in the first operation （93.55%）. Urethral fistula occurred in 1 patient （1/31, 3.22%）, who recovered after the second repair with improved snodgrass operation at 6 months post the first surgery. One patients （3.22%） developed mild meatal stenosis and were successfully managed by simple dilatation. Conclusions：Improved snodgrass operation can retain the urethral plate, and has several advantages including simple technique, short operative time, fewer complications and cosmetic results. Cosmetic results can be gained for the second repair by using improved snodgrass operation. Improved snodgrass operation is a better method for patients with hypospadias.
