A total of 5 patients with recurrent posterior urethral strictures underwent endoscopic placement of an expandable endourethral stent made of titanium. Patient age ranged from 17 to 66 years (mean age 42.6 years). Followup ranged from 13 to 20 months (mean 14.1 months). Of the patients 4 presently have unobstructed voiding with no incontinence. To date no side effects have been directly related to the stents and no incrustations or calculi have formed. Our preliminary study supports the use of titanium urethral stents as an alternative form of treatment for selected urethral strictures.
共有5例复发性后尿道狭窄患者接受了由钛制成的可扩张性尿道内支架的内镜置入术。患者年龄在17至66岁之间（平均年龄42.6岁）。随访时间为13至20个月（平均14.1个月）。其中4例患者目前排尿通畅，无尿失禁。迄今为止，尚未发现与支架直接相关的副作用，也未形成结痂或结石。我们的初步研究支持将钛制尿道支架作为某些尿道狭窄的替代治疗方法。
