BACKGROUND/PURPOSE: The aim of this study was to analyze the complication rate in male bladder exstrophy (BE) patients undergoing flap or graft urethroplasty for the repair of resultant hypospadias after epispadias repair.
We retrospectively reviewed the charts of 22 male BE patients who underwent 24 urethroplasties for resultant hypospadias between 2000 and 2009. Median patient age was 4.2 (range, 1.5-26.5) years, and median follow-up was 7.5 (range, 0.8-10.3) years. Meatal location after epispadias repair was midshaft in 6 cases and proximal shaft in 15. Complications were compared in relation to meatal position, type of urethroplasty (no graft vs graft), use of second-layer coverage of the urethroplasty, and use of suprapubic diversion.
Overall, complications developed in 12 (50%) patients, including 10 urethrocutaneous fistulas and 2 urethroplasty dehiscence. Univariate analysis failed to show any differences between complicated and uncomplicated cases in all the variables. Only the 3 cases undergoing a 2-stage repair had fully successful outcomes.
Urethroplasty in patients with BE has a high complication rate. Quality of local tissue and presence of scarring are possibly the 2 major determinants of a poor outcome. A staged repair seems the safest, although this commits the patient to 2 procedures.
背景/目的:本研究旨在分析接受皮瓣或移植物尿道成形术修复伴有尿道下裂的男性膀胱外翻(BE)患者的并发症发生率。
我们回顾性分析了 2000 年至 2009 年间接受 24 例尿道成形术修复伴有尿道下裂的 22 例男性 BE 患者的病历。患者中位年龄为 4.2 岁(范围,1.5-26.5 岁),中位随访时间为 7.5 年(范围,0.8-10.3 年)。修复性尿道下裂术后尿道口位置位于阴茎干中部的有 6 例,位于阴茎近端的有 15 例。比较了尿道口位置、尿道成形术类型(无移植物 vs 移植物)、尿道成形术第二层覆盖、耻骨上引流等因素与并发症的关系。
总体而言,12 例(50%)患者发生并发症,包括 10 例尿道皮肤瘘和 2 例尿道成形术裂开。单因素分析显示,所有变量在复杂病例和非复杂病例之间均无差异。仅 3 例接受 2 期修复的患者获得了完全成功的结果。
BE 患者的尿道成形术具有较高的并发症发生率。局部组织质量和瘢痕存在可能是不良结局的两个主要决定因素。分期修复似乎是最安全的,但这需要患者接受 2 次手术。
