One hundred and forty three patients who had urethroplasty for urethral stricture between 1980 and 1989 were reviewed. Their age ranged from nine to 75 years with a mean of 39 +/- 10.2 SD years. Infection caused stricture in 51% and trauma in 46.9%. Urethral trauma resulted mostly from road traffic accidents. The inflammatory strictures were located in the anterior urethra, whilst traumatic ones were in the bulbomembranous region. Urethroplasty was indicated as the initial treatment in 80.4% because the strictures were impassable or complicated by perineal sepsis or fistulae. In 16% urethroplasty was employed as an alternative to frequent or complicated urethral dilatation. Sixty (42%) patients had anastamotic urethroplasty while 54.5% had island patch urethroplasty using scrotal, penile or preputial island skin flap. The commonest late complication was restricture which occurred in 20.9% of the patients. Overall, 72% were satisfied with their treatment. Urethroplasty is advocated upon less strict indications as it cures the stricture and prevent the complications of repeated instrumentation.
对1980年至1989年间因尿道狭窄接受尿道成形术的143例患者进行了回顾性研究。他们的年龄在9岁至75岁之间，平均年龄为39±10.2标准差岁。51%的狭窄由感染引起，46.9%由创伤引起。尿道创伤主要源于道路交通事故。炎性狭窄位于前尿道，而创伤性狭窄位于球膜部。80.4%的患者将尿道成形术作为初始治疗方法，因为狭窄无法通过或并发会阴败血症或瘘管。16%的患者采用尿道成形术替代频繁或复杂的尿道扩张术。60例（42%）患者接受了吻合性尿道成形术，54.5%的患者采用阴囊、阴茎或包皮岛状皮瓣进行岛状补片尿道成形术。最常见的晚期并发症是再狭窄，发生率为20.9%。总体而言，72%的患者对治疗满意。由于尿道成形术可治愈狭窄并预防反复器械操作的并发症，因此在适应证不太严格的情况下也提倡采用。
