目的:分析32例输尿管结石ESWL治疗失败的原因。方法:应用Dornier compact Delta-Ⅱ型体外冲击波碎石机对416例输尿管结石患者行ESWL治疗,其中32例经2～3次碎石后,结石未排出而改用输尿管镜或腹腔镜手术治疗。结果:32例失败患者中,22例结石全部粉碎或部分粉碎,因输尿管病变未排除;10例未击碎。结论:ESWL治疗输尿管结石必须严格选择病例,聚焦定位必须准确;结石长期固定输尿管同一位置致中重度肾积水患者,若首次治疗无结石排除,应及时改变治疗方法,避免过度治疗。
Objective: To analyze the causes of failure of 32 cases of ureteral calculi treated with ESWL. Methods: 416 patients with ureteral calculi underwent ESWL treatment with Dornier compact Delta-Ⅱ extracorporeal shock wave lithotripsy machine. Among them, 32 cases were treated with ureteroscopy or laparoscopic surgery without stones after 2 ~ 3 times gravel. Results: Of the 32 patients who failed, all 22 patients had crushed or partially crushed stones, which were not eliminated due to ureteral disease. Ten patients did not crush. CONCLUSIONS: ESWL should be treated with strict selection of the ureteral calculi. The focus of the ESWL treatment must be accurate. The patients with moderate and severe hydronephrosis who have the same location of ureteral stones for a long time should be treated with ESWL to avoid over-treatment.
