The tubularized incised plate (TIP) hypospadias repair is currently the most widely used urethroplasty technique. The most significant post-TIP complication is urethrocutaneous fistula (UCF) development. Tunneled tunica vaginalis flap (TVF) is a well-described technique for the repair of UCF. We retrospectively reviewed all patients undergoing repeat repair of UCF after TIP repair from 2001 to 2005. Twelve boys underwent TVF repair at our institution for recurrent UCF. Fistulae ranged from distal penile to penoscrotal in location. Median surgical time was 45 minutes and no postoperative complications occurred. After a median follow-up of 32 months (range 16-48 months), no patient has yet had a recurrence of UCF. In conclusion, TVF repair is a successful technique for the treatment of UCF after previous failed repair. TVF is technically simple to perform and should be considered for treating UCF following TIP urethroplasty, particularly in a repeat surgical setting.
管状切开板（TIP）尿道下裂修复术是目前应用最广泛的尿道成形术。TIP术后最显著的并发症是尿道皮肤瘘（UCF）的形成。带蒂睾丸鞘膜瓣（TVF）是一种用于修复UCF的成熟技术。我们回顾性分析了2001年至2005年间所有接受TIP修复术后UCF再次修复的患者。12名男孩在我们机构接受了TVF修复复发性UCF。瘘管位置从阴茎远端到阴茎阴囊。中位手术时间为45分钟，术后无并发症发生。中位随访32个月（范围16 - 48个月）后，尚无患者出现UCF复发。总之，TVF修复术是治疗先前修复失败后UCF的一种成功技术。TVF技术操作简单，在TIP尿道成形术后治疗UCF时应予以考虑，尤其是在再次手术的情况下。
