概括

与传统的瘤尿道支架相比,MemoKathTM-051支架的内置时间更长,但并发症率更高. 需要进一步的研究来确定尿管支架的最佳候选者.

科学领域:

尿道病学
医疗器械
癌症学

背景情况:

由于良性或恶性疾病导致的尿道阻塞需要插入支架.
MemoKathTM-051 (MK) 是一个可热扩展的螺旋支架,旨在长期内置.
与传统瘤尿路支架 (TUS) 相比,MK支架的结果数据不一致.

研究的目的:

在尿管阻塞患者中,将MK支架与TUS的疗效和安全性进行比较.
调查MK在停留时间和并发症率方面的优势.

主要方法:

在72名尿管狭窄症 (良性或恶性) 患者的单中心回顾分析中.
在2008年3月至2018年12月期间,患者接受了MK支架或TUS.
两种支架类型之间的停留时间,并发症率 (Clavien-Dindo分类) 和并发症时间的比较.

主要成果:

总共分析了171个尿路单元 (89个MK,82个TUS).
术后并发症发生在92%的MK患者和23%的TUS患者中 (p=0. 01).
复杂症的中位时间为MK (5. 6个月) 比TUS (3. 5个月) (p=0. 01) 长,而中位时间为MK替换支架为8个月,而TUS为5. 2个月 (p<0. 001).

结论:

虽然MK支架提供了显著更长的停留时间,但与TUS相比,它与更高的并发症率和更早的更换有关.
需要进一步的研究来确定失败的预测因素,并确定每个类型的尿路支架的理想候选患者.
