Permanent metallic stents have found wide application for use in the vascular and biliary systems and currently devices are also available for use in the urinary tract. Permanent stenting of the ureter has proven to be an useful option in the management of obstruction caused by external compression due to malignancy whereas the efficacy of permanent stenting in the treatment of benign ureteral strictures is still controversial. We treated three patients with benign ureteral strictures by implantation of a self-expanding endoluminal stent that resulted in ureteral patency persisting up to 24 months.
永久性金属支架已在血管和胆道系统中得到广泛应用，目前也有可用于泌尿道的装置。事实证明，永久性输尿管支架置入术是治疗恶性肿瘤引起的外部压迫所致梗阻的一种有效选择，而永久性支架置入术治疗良性输尿管狭窄的疗效仍存在争议。我们通过植入自膨式腔内支架治疗了3例良性输尿管狭窄患者，输尿管通畅持续了24个月。
