目的探讨体外冲击波碎石术(ESWL)治疗双J管置管时间过长伴结石形成致拔管困难的疗效.方法 21例因双J管置管时间过长伴结石形成致拔管困难的患者应用双定位碎石机行ESWL治疗,经B型超声和X线定位,冲击电压从5.0 kV开始逐渐加至9.0 kV,冲击次数1000～2000次,对患者治疗后拔管成功率及拔管前后血、尿检验指标进行回顾性分析.结果 21例患者经ESWL治疗1～3次后拔管成功20例,失败的1例患者改行开放手术取出双J管.拔管前后尿、血检验指标差异均无统计学意义(均P＞0.05),但拔管后尿WBC(4个～+/HP)较拔管前(+～+++/HP)明显减少.结论 ESWL治疗双J管置管时间过长伴结石形成致拔管困难者安全性好、成功率高、并发症少.

Objective To discuss the effect of extracorporeal shock wave (ESWL) for difficult decannulation caused by double J catheter calculi. Methods Twenty-one cases with difficult decannulation were treated by ESWL. They were localized by B-ultrasound and X-ray. The impulse voltage was gradually increased to 9.0kV from 5.0kV for 1000-2000 times. The success rate of decannulation, the inspection index of blood and urine before and after decannulation were retrospectively analyzed. Results Twenty cases successed in decannulation after treated for 1-3 times. The other case was turned to open surgery to remove the detaining double J catheter. Before and after extubation, the urine and blood tests indexes had no statistical significance( P ＞0.05 ), but the WBC of urine after extubation(4 ～ +/HP) was obviously less than that before extubation( + ～ + + +/HP). Conclusion ESWL for difficult decannulation caused by double J catheter calculi is safe with high success rate and few complications.
