目的 报告电磁式体外冲击波原位治疗中段输尿管结石疗效。方法 患者５４例,结石直径为５－２０ｍｍ,平均１１ｍｍ。ＥＳＷＬ治疗时经侧腹部入路并采用工能量冲击技术。工作电压２－７档,发射次数每序列３０００－５０００次,治疗结果代入效率商公式测算。结果 碎石治疗３个月内无石率为９６％,复震率３０％,效率商７４％。

Extracorporeal shock wave lithotripsy in situ for middle ureteral stones

Objective To report the experience with in situ ESWL for patients with middle ureteral stones.HZMethods 52 patients suffering from stones with an average 11 mm (range 520 mm) in dimension were treated using modified Puigvert technique in prone position via the entry route of lateral abdomen.The patients received 3 0 005 0 00 shocks per session at the power setting ranged from 2 to 7. Results The stone free rate at 3 months was achieved in 96% patients retreatment was performed in 30% patients. The therapeutic results were calculated as efficiency quotient being 74%. No severe complications occured in all patients. Conclusions In situ ESWL for middle ureteral stone is safe and effective and may serve as the first line therapy.
