输尿管狭窄的介入治疗(附10例报告)

Interventional Treatment of Ureteral Stricture

目的 探讨输尿管狭窄介入治疗的插管技术及提高疗效的方法。方法 10例经IVP或逆行造影确诊的输尿管狭窄的病人 ,用改制的输尿管导管引入导丝、直头导管扩张狭窄段后再行球囊扩张、双J管及内支架置入 ,2 0～30天拔出双J管。结果 除 1例未成功外 ,9例均完成了球囊扩张及双J管置入术。拔出双J管后复查IVP见狭窄段明显扩张 ,肾盂积水明显改善。其中 1例 1年后又狭窄 ,再次行球囊扩张及内支架置入后 1年未再狭窄。结论 用改制的输尿管导管插管 ,直头导管及球囊扩张术治疗输尿管狭窄 ,技术成功率高。而双J管及内支架置入能明显提高疗效。
