“宽焦斑-低压力”电磁式冲击波碎石术治疗上尿路结石

Electromagnetic type ESWL of Wide-focus and Low-pressure for the treatment of urinary calculi

目的 :观察“宽焦斑 低压力”电磁式体外冲击波碎石术 (ESWL)治疗肾、输尿管结石的疗效及并发症。方法 :B超定位 ,应用CS 2 0 1 2A型碎石机“宽焦斑 低压力”治疗泌尿系结石 5 2 5例 ,工作电压 6 .5～ 9.0kV ,平均冲击剂量 (1 2 91± 1 90 )次。结果 :一次碎石后排净率 5 1 .5 %,3个月后总排净率 85 .8%,碎石成功率 97.9%,无严重副反应发生。结论 :“宽焦斑 低压力”电磁式体外冲击波碎石机治疗泌尿系结石安全性大 。

Purpose:To evaluate the effectiveness and complication of electromagnetic ESWL of low pressure and wide focus in patients with renal and ureteral calculi.Methods:Electromagnetic ESWL of wide focus and low pressure with B mode ultrosound location was used in 525 patients for treatment of urinary calculi. Working voltage 6.5 ～ 9.0 kV and (1 291±190) times of average impact dose were chosen.Results:The successful lithotripsy was carried out in 97.9 % stones.There was no serious side reaction in all patients.The stone free rate was 51.5 % soon after the lithotripsy treatment and total stone free rate was 85.8 % 3 months following ESWL treatment.Conclusions:Electromagnetic extracorporeal shock wave lithotripsy of wide focus and low pressure was a safe and satisfactory treatmenl method for urinary calculi.
