Division of the proximal urethal plate and skin graft at the ventral surface of the penis for severe hypospadias

目的探讨治疗严重型尿道下裂的方法。方法一期将尿道板近端切断，矫正阴茎下弯，腹侧创面移植阴囊中厚皮片，半年后二期手术塑造尿道。结果2004年2月至2005年3月，于临床应用17例，分期手术均成功，无尿道狭窄和尿瘘等并发症发生。1年后随访观察，阴茎头及尿道外口形态良好，阴茎矫直完全，术后阴茎阴囊形态尚佳。结论该手术方法操作简便，手术时间短，适用于阴茎近端型和阴茎阴囊型伴有重度阴茎下弯的尿道下裂患者。

Objective To explore a technique for the treatment of severe hypospadias. Methods At the first stage, the proximal end of the urethra plate was divised and the chordee was corrected, followed by skin graft at the ventral surface of penis. The urethraplasty was performed at the second stage half a year later. Results From Feb.2004 to Mar.2005,17 cases were treated successfully without any complication. After one year of following up, the appearance of glan and the urethral meatus was good and the cordee was corrected completely. The appearance of penis and scrotum was also satisfactory.
