OBJECTIVE
To discuss the methods for urethral external meatus and glanuloplasty after correction of hypospadias.
METHODS
The V shape flap on the dorsal side of glan, combined with the bilateral glan flaps were moved to the ventral side. The flap at the ventral side of urethral external meatus was turned over. Then the urethral external meatus was repositioned to the top end of glan with the ventral defects covered by the dorsal flaps. Then the coniform glan was reconstructed.
RESULTS
From January 2008 to December 2013, 28 cases were treated, including glandular hypospadias, postoperative retraction of external urethral meatus and meatal stenosis. 21 patients were followed up for 1 -12 months (average, 1 month) with marked improvement of glan appearance and retraction of external meatus. No meatal stenosis happened.
CONCLUSIONS
Postoperative retraction of urethral external meatus and meatal stenosis can be corrected by V shape flap on the dorsal side of glan combined with the bilateral glan flaps. The flat appearance of glan can be improved. It is an ideal method for glandular hypospadias.
目的
探讨尿道下裂矫正术后尿道口及龟头成形的方法。
方法
将龟头背侧的V形皮瓣与双侧龟头皮瓣向腹侧移位，翻转尿道口腹侧皮瓣，将尿道口重新定位到龟头顶端，背侧皮瓣覆盖腹侧缺损，重建圆锥状龟头。
结果
2008年1月至2013年12月，共治疗28例，包括阴茎头型尿道下裂、术后尿道口退缩及尿道口狭窄。21例患者随访1 - 12个月（平均1个月），龟头外观明显改善，尿道口退缩，无尿道口狭窄发生。
结论
龟头背侧V形皮瓣联合双侧龟头皮瓣可矫正术后尿道口退缩及尿道口狭窄，改善龟头扁平外观，是治疗阴茎头型尿道下裂的理想方法。
