摘 要 目的:观察输尿管镜下逆行放置Allium覆膜尿路支架系统(以下简称Allium支架)治疗输尿管单处顽固性狭窄的安全性和有效性。方法:回顾性分析17例接受Allium支架治疗的输尿管单处顽固性狭窄患者的临床资料。记录患者术后并发症和手术前、后肾积水情况等。结果:对所有患者均一期手术成功。并发症发生率为23.5%。患者术前、术后肾积水情况中位数分别为27和20 mm,术后情况较术前显著改善(P<0.001)。结论:Allium支架对输尿管狭窄段的扩张、支撑效果较好,为慢性、复杂性输尿管狭窄患者提供了一种有价值的治疗选择。由于该支架放置时间尚短,远期效果还待进一步的随访观察。

ABSTRACT Objective: To observe the safety and efficacy of retrograde placement of an Allium-covered urinary stent system (Allium stent) under ureteroscopy for the treatment of single refractory strictures of the ureter. Methods: Clinical date from 17 patients treated with an Allium stent for single refractory stricture of the ureter were retrospectively analyzed. The incidence of postoperative complications and the remission rate of hydronephrosis were recorded. Results: All patients were successfully operated at one stage. The complication incidence was 23.5%. The median preoperative and postoperative hydronephrosis was 27 mm and 20 mm, and the postoperative condition was significantly improved compared with preoperative one (P<0.001). Conclusion: The Allium stent has better expansion and support effect on ureteral strictures and can provide a valuable therapeutic option for patients with chronic and complicated ureteral strictures. However, its long-term efficacy still requires further follow-up observation because the placement time of the stent is short.

尿管狭窄是泌尿外科领域的难治性疾病,常见于输尿管结石嵌顿和内镜碎石术后患者,也见于妇科和膀胱肿瘤治疗后、输尿管扩张术后复发和医源性输尿管损伤等患者,治疗方法主要有输尿管狭窄段切除联合输尿管端-端吻合术、输尿管镜治疗、回肠或膀胱肌瓣代输尿管成形术等。但部分顽固性输尿管狭窄经上述方法治疗后仍复发,需长期放置或更换输尿管支架。Allium覆膜尿路支架系统(以下简称Allium支架)是一种以镍钛合金为骨架的新型自扩张输尿管支架,其口径和径向支撑力均优于传统的输尿管支架,可用于治疗经其他方法治疗后复发的顽固性输尿管狭窄[1-3]。我们于2019年5月―2020年12月应用Allium支架治疗输尿管单处顽固性狭窄患者17例,效果较好,现总结报告如下。
1.1 临床资料
本研究患者数17例,其中男10例、女7例,年龄中位数为45岁(22 ~ 75岁)。17例患者中,有输尿管镜碎石术后输尿管狭窄7例,输尿管镜碎石术中发现的输尿管息肉伴狭窄5例,子宫内膜癌手术联合放疗后输尿管狭窄2例,体检中发现的输尿管狭窄3例,他们均为经输尿管镜或输尿管狭窄段切除术治疗后仍有单处狭窄患者,且均存在中重度肾积水情况。这些患者的输尿管狭窄长度中位数为20 mm(8 ~ 50 mm),其中输尿管上段狭窄13例,下段狭窄4例。17例患者在接受Allium支架置入术前均接受了增强CT尿路成像和逆行尿路造影检查以明确输尿管狭窄部位及长度。
