An expandable titanium stent was used as an alternative to standard treatment for urinary obstruction in 20 men. Six patients had recurrent urethral strictures. Fourteen patients had obstruction secondary to benign prostatic hyperplasia (BPH) and were considered high risk surgical candidates. Complete results with a mean follow-up of 12 months are available for 11 patients. Four of the six stricture patients are currently unobstructed. All seven of the available men with BPH are voiding well. No side effects have been related to the stents, and no encrustations or calculi have formed.
20名男性患者使用可扩张钛支架作为尿路梗阻标准治疗的替代方案。6名患者有复发性尿道狭窄。14名患者因良性前列腺增生（BPH）导致梗阻，被认为是高风险手术候选者。11名患者可获得平均随访12个月的完整结果。6名狭窄患者中有4名目前尿路通畅。所有7名有BPH的可用男性排尿良好。未发现与支架相关的副作用，也未形成结痂或结石。
