To evaluate our results with buccal mucosa free grafts in salvage urethroplasty.
Retrospective chart review of autologous buccal mucosa grafts for urethral reconstruction at Winnipeg Children's Hospital and Children's Hospital of Eastern Ontario between November 1992 and March 2000.
Nine patients (median age 4 years) underwent such reconstruction. Seven of the nine patients had experienced failed previous attempts at hypospadias repair. Onlay grafts were used in all but one patient who required a tube graft. Urethrocutaneous fistula was the most common post-operative complication, affecting four of nine patients. Two patients developed urethral strictures and one a meatal stenosis. Satisfactory functional results were ultimately achieved in all patients. Harvest site complications were minimal.
Buccal mucosa is a readily available and useful source for urethral grafting material, but should only be used in patients with insufficient penile skin. Grafts may be used as onlays or tubes. It is our experience that despite precautionary measures, fistulae and strictures are common.
评估我们在挽救性尿道成形术中使用颊黏膜游离移植物的结果。
对1992年11月至2000年3月期间在温尼伯儿童医院和东安大略儿童医院进行自体颊黏膜移植物尿道重建的病例进行回顾性图表分析。
9例患者(中位年龄4岁)接受了此类重建手术。9例患者中有7例之前的尿道下裂修复尝试失败。除1例需要管状移植物的患者外,其余均采用覆盖移植物。尿道皮肤瘘是最常见的术后并发症,9例患者中有4例受影响。2例患者出现尿道狭窄,1例出现尿道口狭窄。所有患者最终均获得了满意的功能结果。供区并发症极少。
颊黏膜是一种易于获取且有用的尿道移植材料来源,但仅应用于阴茎皮肤不足的患者。移植物可作为覆盖物或管状使用。根据我们的经验,尽管采取了预防措施,瘘管和狭窄仍很常见。
