Neourethral diverticulum secondary to distal neourethral stenosis is not uncommon after proximal hypospadias repair. We describe a technique using the neo urethral diverticular roof and overlying skin as a composite flap to reconstruct the urethral stenosis distal to the diverticulum. The composite flap is advanced distally for reconstruction of the stenosed urethra either as a tube or as an onlay. Urethra at the diverticular bed is tubularized to reduce its caliber. This technique has yielded excellent results in three children. The tissue expansion caused by the obstructed urinary stream has been utilized to correct both neourethral diverticulum and stenosis.
近端尿道下裂修复术后，继发于远端新尿道狭窄的新尿道憩室并不少见。我们描述了一种技术，即使用新尿道憩室顶部和覆盖其上的皮肤作为复合皮瓣，来重建憩室远端的尿道狭窄。复合皮瓣向远端推进，以管状或覆盖的方式重建狭窄尿道。将憩室床处的尿道制成管状以减小其管径。该技术在三名儿童中取得了优异的效果。利用尿流梗阻引起的组织扩张来纠正新尿道憩室和狭窄。
