(Objectives) To compare efficacy and outcome of urethroplasty for complicated anterior urethral strictures. (Methods) Twelve patients, included 3 boys, with anterior urethral stricture underwent urethroplasty after the failure of either urethral dilatation or internal urethrotomy. We evaluated pre- and post-operative Q max and surgical outcome. (Results) Four patients were treated with end-to-end anastomosis, included a case of bulbar urethral elongation simultaneously, one patient was treated with augmented anastomotic urethroplasty, three patients were treated with onlay urethroplasty with prepucial flap, one patient was treated with tubed urethroplasty with prepucial flap (Ducket procedure) and three patients were treated with onlay urethroplasty with buccal mucosal graft. Postoperative Qmax improved in all patients without major complications and recurrence during follow-up periods ranging from 17 to 102 months (mean 55 months). (Conclusions) Urethroplasty is an effective therapeutic procedure for complicated anterior urethral stricture.
（目的）比较复杂性前尿道狭窄尿道成形术的疗效和结果。（方法）12例前尿道狭窄患者（包括3名男孩）在尿道扩张或尿道内切开术失败后接受了尿道成形术。我们评估了术前和术后的最大尿流率（Q max）及手术结果。（结果）4例患者接受端端吻合术，其中1例同时行球部尿道延长术；1例接受扩大吻合尿道成形术；3例接受带蒂包皮瓣覆盖尿道成形术；1例接受带蒂包皮瓣管状尿道成形术（Ducket手术）；3例接受颊黏膜移植覆盖尿道成形术。所有患者术后最大尿流率均有所改善，随访17至102个月（平均55个月）期间无重大并发症及复发。（结论）尿道成形术是治疗复杂性前尿道狭窄的有效方法。
