B超定位在ESWL治疗泌尿系结石中的应用

Treatment of urinary stones by ESWL with B-ultrasound localization

目的探讨如何提高B超定位指导ESWL治疗尿路结石的效果。方法运用B超定位指导电磁冲击波体外碎石机检查治疗泌尿系结石988例。结果 988例尿路结石检出率达100.00%,经用超声定位及超声复查,本次尿路结石经碎石治疗总有效率为87.04%(860/988)。结果 988例尿路结石检出率达100.00%,一次碎石成功率68.02%(672/988),两次碎石成功率为87.04%(860/988)。结论在ESWL治疗输尿管结石过程中,B超可以独立完成碎石病例的筛选,焦点定位,术中观察及疗效判断等步骤,应用B超定位指导ESWL可使尿路结石的碎石总有效率明显提高。

【Objective】To explore how to improve the effect of extracorporeal shock wave lithotripsy（ESWL） in treatment of urinary stones with B-ultrasound localization.【Methods】ESWL was carried out for 988 cases of urinary stones with a electromagnetic ESWL lithotripter.【Results】The detection rate with urinary stone in 988 patients reached 100%,the success rate of one lithotripsy was 68.02%（672/988）,the success rate of two times lithotripsy was 87.04%（860/988）.【Conclusions】In the process of treatment of ureteral stones by ESWL,B-ultrasound can independently accomplish the selection of urinary stone cases,localization of the focus,intraoperative observation,effect judgment and other steps,ESWL by B-ultrasound localization can improve the total curative effect of urinary stones.
