摘要
目的采用压电、液电和电磁式第二代体外冲击波碎石机治疗输尿管下段结石，观察和比较其疗效。方法１９８７年以来共收治输尿管下段结石患者６０３例。按机型分为３组：ＥＤＡＰＬＴ０１压电组１７９例，ＪＤＰＮＩＶ型液电组２９４例，ＤｏｒｎｉｅｒＣｏｍｐａｃｔＳ型电磁组１３０例。每组按结石大小又分为＜１０ｍｍ、１０～１５ｍｍ和＞１５ｍｍ３个亚组。结果电磁组的一次性无石率高于其它两组，压电组的效率商低于液电组和电磁组。小于１５ｍｍ结石的液电式和电磁式ＥＳＷＬ的一次性无石率超过７０％。结论对于输尿管下段结石的ＥＳＷＬ治疗，电磁组和液电组的效果优于压电组，ＥＳＷＬ是治疗＜１５ｍｍ结石的最佳选择。
Objective To treat patients with lower ureteral stones by extracorporeal shock wave lithotripsy (ESWL) using piezoelectric, electrohydraulic and electromagnetic second lithotriptors. Methods Six hundred and three patients were divided into 3 groups according to the modes of lithotriptors.There were 179 patients in EDAP LTO1 piezoelectric group, 294 in JDPN IV electrohydraulic group and 130 in Dornier Compact S electromagnetic group.Every group was further divided into 3 subgroups with 10 mm, 10～15 mm and 15 mm in diametors of stones. Results The stone free rate in single session of ESWL was higher in the electromagnetic group than in the other two groups. The efficiency quotient was lower in piezoelectric group than in the electrohydraulic and electromagnetic groups.The stone free rate in single session was achieved in more than 70% of stones less than 15 mm in diameter for electromagnetic and electrohydraulic ESWL. Conclusions The overall results of electromagnetic and electrohydraulic ESWL on lower ureteral stones are better than those of piezoelectric ESWL,and ESWL is sui table for stone less than 15 mm in diameter.
