北京医科大学人民医院与中国科学院电工研究所、力学研究所联合研制成功E8410型冲击波肾碎石治疗机,并初步应用于临床。本文扼要阐述液电冲击波体外破碎肾结石的技术原理及该机的主要特性,并介绍应用该技术治疗18例肾和上段输尿管结石的初步经验。全部病例经治疗效果满意,排出体外的碎石标本干燥重量为2.0～0.1g之间。碎石过程中患者无痛 People’s Hospital of Beijing Medical University and the Chinese Academy of Sciences Institute of Electrical Engineering, Institute of Mechanics jointly developed E8410 shock wave lithotripsy machine, and initially applied to clinical. This article briefly expounds the technical principle of ESWL crushing kidney stones and the main features of the machine, and introduces the preliminary experience of using this technique in the treatment of 18 cases of upper ureteral calculi. All cases were treated with satisfactory results, excreted gravel specimens dry weight between 2.0 ~ 0.1g. Gravel in the process of painless patients
