B超定位在体外冲击波碎石治疗输尿管结石中的应用体会

B-ultrasound guided treatment of ureteral calculi with extracorporeal shock wave lithotripsy

目的:探讨B超定位在体外冲击波碎石(ESWL)治疗输尿管结石的临床价值。方法:回顾性分析1999年6月～2008年12月运用WD-ESWL91型和HK.ESWL-Vm型碎石机在B超定位下对681例输尿管结石进行碎石治疗的临床资料,并观察治疗过程,电压,冲击次数,声像图特点等情况。结果:681例输尿管结石中,一次性碎石成功171例(25.1%),复震292例(42.9%),碎石失败218例(32.0%),有效率为68.0%。结论:B超定位准确、安全、无辐射,是ESWL治疗输尿管结石定位的主要方法之一。

Objective： To investigate the clinical value of treating ureteral calculi with extraeorporeal shock wave lithotripsy under the guidance of B-ultrasound. Methods. Clinical data of 681 eases of ureteral calculi that underwent extraeorporeal shock wave lithotripsy operation （WD-ESWL91 or HK. ESWL-Vm） under the guidance of B-ultrasound were retrospective analyzed. Related information such as voltage, shock times and the B-ultrasound images were also analyzed. Results： With a total effective rate of 68.0% , 171 out of the 681cases had calculus crushed after one treatment （25.1% ）, 292 cases （42.9%） underwent subsequent treatment and 218 eases （32.0%） failed. Conclusion. As a safe, accurate method which is also free of radiation, B-ultrasound is a prefenced method for localization in the treatment of nreteral calculi with extracorporeal shock wave lithotripsy.
