目的探讨输尿管结石采用原位体外冲击波碎石（ＥＳＷＬ）治疗失败的原因。方法对输尿管结石患者采用ＥＳＷＬ治疗对其中碎石失败者改用输尿管切开取石术。结果在２４２２例患者中２３例碎石失败（０．９５％），改用输尿管切开取石术治疗。结论对失败的原因归结为：①结石面积过大（横径＞１．２ｃｍ）或停留时间太长（＞３年）；②由于结石长期刺激而导致输尿管的病理改变；③结石梗阻并发严重感染导致患侧肾功能减退。④结石成份以磷酸盐居多。
Objective To investigate the causes of failure of ureteral calculi treated with ESWL. Methods Patients with ureteral calculi treated with ESWL were treated with ureteral incision and lithotomy instead of those with failed lithiasis. Results Twenty-three of the 2422 patients had failed lithotripsy (0.95%) and were treated with ureterolithotomy. Conclusion The reasons for the failure attributed to: ① stone area is too large (diameter> 1.2cm) or residence time is too long (> 3 years); ② due to long-term stones lead to pathological changes of the ureter; ③ stone obstruction complicated by severe infection Lead to ipsilateral renal dysfunction. ④ stones mostly phosphate composition.
