国产与德产电磁式碎石机治疗上尿路结石的疗效比较

A retrospective study comparing the clinical efficacy of a china-made electromagnetic lithotripter and a germany-made electromagnetic lithotripter

目的:比较国产HK-V-ESWL-5型电磁式碎石机(国产机)和德产Dornier Compact S型电磁式碎石机(德产机)治疗上尿路结石的临床疗效。方法:将收治的1 421例上尿路结石患者按碎石机的产地分为国产机组784例和德产机组637例,然后按结石大小和结石部位进行疗效对比。结果:国产机组的3周碎石成功率、复震率及辅治率依次为75%、25%和17%,较德产机组的89%、11%和4%差异有统计学意义(P<0.05)。国产机的EQ值为0.69,低于德产机的0.86。结论:使用国产机和德产机行ESWL治疗均为有效、安全和非侵袭性,但前者的碎石成功率较后者低。

Objective：Compare the clinical outcome of a china-made electromagnetic lithotripter and a germanymade electromagnetic lithotripter made in treatment of patients with upper urinary tract calculi. Methods： 1421patients were divided into 2 groups according to the modes of lithotriptors. There were 784 patients in HK-V-ESWL-5 electromagnetic lithotripter group, 637 in Dornier Compact S electromagnetic lithotripter group. Every group was further divided into 2 subgroups with 〈10 mm and ≥10 mm in diameters of stones,and further divided into 2 subgroups with kidney and ureter in locations of stones. Results：There were statistically significant differences between the HK-V-ESWL-5 electromagnetic lithotripter and the Dornier Compact S electromagnetic lithotripter with respect to stone-free rate, retreatment rate and auxiliary procedure rate. At the time, the Efficacy Quotient（EQ） is 0.69 with the HK-V-ESWL--5 electromagnetic lithotripter and 0. 86 with the Dornier Compact S electromagnetic lithotripter. Conclusions：The PIK-V-ESWL--5 electromagnetic lithotripter and the Dornier Compact S electromag- netic lithotripter both provide an effective, safe and noninvasive treatment for extracorporeal shock wave lithotripsy（SWL） ,but the stone-free rate of the HK-V-ESWL--5 electromagnetic lithotripter is lower.
