体外冲击波碎石术治疗输尿管结石160例疗效差的原因分析

目的对体外冲击碎石术治疗输尿管结石疗效差的原因进行分析。方法分析该院自2002年9月-2005年12月采用国产KDE-2001型X线定位碎石机治疗尿路结石1225例，其中160例输尿管结石疗效不理想。结果160例中53例经多次碎石后结石碎裂排出；87例结石经X线检查证明部份或全部碎裂，但仅有少量结石排出。结论经2、3次ESWL治疗结石无改变者，应改行输尿管肾镜气压弹道碎石术或开放手术治疗。

Treatment of urethral calculi with extracorporeal shock wave lithotripsy: analysis of 16 cases with poor therapeutic efficacy

[Objective] To explore treatment of urethral calculi with extracorporeal shock wave lithotripsy. [Methods] From September 2002 to December 2005, 1 225 patients with urinary calculi were treated with domestie-made KDE-2001-type X-ray fixing lithotripter. Among the total, the therapeutic efficacy turned out to be poor in 160 patients with ureteral calculi. [Result] 53 out of 160 eases passed out the calculi, and 87 were with smashed calculi after shock wave but only passed out small amounts. [Conclusion] After 2 to 3 times of ESWL treatment with no therapeutic effect, we suggest using ureteroseopie air pressure missile lithoclasty.
