Severe chordee with hypospadias may require repair by ventral corporoplasty with a free graft before urethroplasty. We report an 11 year experience with one-stage and two-stage hypospadias repair using dermal grafts.
From 12/1997 to 12/2008, 47 hypospadias with severe chordee were repaired using a ventral dermal graft to correct the chordee. Forty cases were repaired in two stages; the remaining seven patients had adequate preputial skin and were repaired in one stage. In 28 cases the neourethra was covered with both tunica vaginalis and penile dartos flap while 12 were covered only with penile dartos flap. Patients ranged from 12 to 152 months of age. Follow-up ranged from 6 months to 4 years.
28 patients with both tunica vaginalis and dartos flap had 7 urethral fistulas and 2 developed meatal stenosis. 12 patients with only penile dartos flap had 3 fistulas and 2 had meatal regression. The seven patients who underwent a one-stage repair had good results with a straight penis and no evidence of urethral fistula or urethral stenosis.
Dermal graft can be performed in one or two stage hypospadias repair. Complication rates are similar to other standard repairs for proximal hypospadias.
重度阴茎下弯合并尿道下裂可能需要在尿道成形术前通过带游离移植物的腹侧阴茎成形术进行修复。我们报告了使用真皮移植物进行一期和二期尿道下裂修复的11年经验。
从1997年12月至2008年12月,47例重度阴茎下弯的尿道下裂患者采用腹侧真皮移植物修复阴茎下弯。40例分两期修复;其余7例患者包皮皮肤足够,进行一期修复。28例患者的新尿道用鞘膜和阴茎肉膜瓣覆盖,12例仅用阴茎肉膜瓣覆盖。患者年龄在12至152个月之间。随访时间为6个月至4年。
28例采用鞘膜和肉膜瓣覆盖的患者中有7例发生尿道瘘,2例出现尿道口狭窄。12例仅采用阴茎肉膜瓣覆盖的患者中有3例发生瘘管,2例出现尿道口退缩。7例接受一期修复的患者效果良好,阴茎伸直,无尿道瘘或尿道狭窄迹象。
真皮移植物可用于一期或二期尿道下裂修复。并发症发生率与近端尿道下裂的其他标准修复方法相似。
