摘　　要：目的探讨尿道下裂修复手术后尿道外口和阴茎头成形的方法。方法通过尿道外口背侧V形瓣及两侧阴茎头组织瓣的移位，及将尿道外口腹侧组织瓣翻转，共同使腹侧的尿道外口向背侧移位至阴茎头顶端，尿道外口腹侧缺损得以修复，两侧阴茎头组织瓣向腹侧移位，共同形成锥状阴茎头。结果2008年1月至2013年12月，于临床修复28例，包括阴茎头型尿道下裂、尿道下裂修复术后尿道外口退缩和尿道外口狭窄。21例患者获得随访，时间为1～12个月，平均1个月，均无尿道外口狭窄出现，龟头外形及尿道外口退缩得到明显改善。结论应用尿道外口背侧v形瓣及两侧阴茎头组织瓣的合理移位，可以矫治尿道下裂修复术后尿道外口退缩、尿道外V／狭窄，改善扁平阴茎头的形态，并可用于阴茎头型尿道下裂的修复。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 he 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.
