BACKGROUND/PURPOSE: Secondary procedures to correct complications after hypospadias repair remain challenging especially for "hypospadias cripples." The tubularized, incised plate urethroplasty was first introduced by Snodgrass for the repair of primary hypospadias in 1993. The authors used this procedure to correct the complications after hypospadias repair in patients who had no abundant local skin flaps to be used for a neourethra.
Six patients underwent tubularized, incised plate urethroplasty for the correction of complications of hypospadias repair performed the previous year, including a large urethrocutaneous fistula (n = 1) and disruption of the neourethra (n = 5). Prior surgical procedures included transverse island tube urethroplasty in 4 cases and 2-stage urethroplasty in 2 cases. The average patient age at the time of secondary procedure was 4.6 years (range, 1 to 12 years).
The mean follow-up period was 6 months (range, 2 months to 1 year). All the patients obtained a functional neourethra with a vertical, slitlike meatus. A small fistula developed in one child and mild meatal retraction in another.
The tubularized, incised plate urethroplasty offers few complications and good cosmetic results. The authors recommend its use for patients who have had repeated surgeries for hypospadias repair, especially those in whom only limited local skin flaps can be utilized for a neourethra.
背景/目的:修复尿道下裂术后并发症的二次手术仍然具有挑战性,尤其是对于“尿道下裂致残者”。1993年,斯诺德格拉斯首次引入管状切开板尿道成形术用于一期尿道下裂修复。作者采用该手术方法,为那些没有足够局部皮瓣用于新尿道重建的尿道下裂修复术后并发症患者进行矫正。
6例患者接受管状切开板尿道成形术,以矫正上一年度尿道下裂修复术后的并发症,包括巨大尿道皮肤瘘(1例)和新尿道破裂(5例)。既往手术包括4例横行岛状管尿道成形术和2例两期尿道成形术。二次手术时患者的平均年龄为4.6岁(范围1至12岁)。
平均随访期为6个月(范围2个月至1年)。所有患者均获得了具有垂直、裂隙状尿道口的功能性新尿道。1名儿童出现小瘘管,另1名儿童出现轻度尿道口回缩。
管状切开板尿道成形术并发症少,美容效果好。作者推荐将其用于那些因尿道下裂修复而接受多次手术的患者,尤其是那些仅有有限局部皮瓣可用于新尿道重建的患者。
