本文介绍了作者在近５年时间里，采用西德Ｗｏｌｆ体外冲击波碎石机（该机使用超声影像定位系统）共治疗３００６例尿路结石病人和４１０例胆结石病人的经验。本文将超声定位系统与Ｘ线定位系统做了比较。结果显示超声定位不仅可替代Ｘ线定位，而且还可以显示透Ｘ线的阴性结石。同时还可以定位和治疗胆囊结石。超声不仅可清楚定位不同部位的尿路结石。而且还可以鉴别一些不适宜碎石治疗的泌尿系统疾病。如肾髓质海绵肾和肾盏憩室合并结石等疾病。超声影像定位可实时显示碎石治疗的全过程，一旦发现结石被粉碎，治疗即可结束。
This article presents the authors’ experience of treating 3006 patients with urolithiasis and 410 patients with gallstone disease with the West German Wolf Extracorporeal Impact Blasting Crusher (the machine uses an ultrasound imaging system) in the past five years. In this paper, ultrasonic positioning system and X-ray positioning system are compared. The results show that ultrasound localization can not only replace the X-ray positioning, but also can show X-ray negative stones. Gallstone can also be located and treated at the same time. Ultrasound can not only clearly locate different parts of the urinary tract stones. But also can identify some of the ill-suited lithotripsy urological diseases. Such as renal medullary sponge kidney and calyceal diverticulum with stones and other diseases. Ultrasound imaging can be real-time display gravel treatment of the whole process, once found the stones are crushed, the treatment can be ended.
