改良Snodgrass术治疗尿道下裂疗效观察

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。

Effect Observation of Improved Snodgrass Operation for Hypospadias

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), pe-nile 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 cos-metic results. Cosmetic results can be gained for the second repair by using improved snodgrass operation. Im-proved snodgrass operation is a better method for patients with hypospadias.
