Treatment of transparent and semi-transparent ureteral calculi with ESWL underX-ray

应用体外震波碎石术（ＥＳＷＬ）治疗各种类型上尿路结石３９６８例，其中透光和半透光（低密度）结石分别占１．０６％和３．４０％，以常规静脉尿路造影（ＩＶＵ）为依据，分４组：（１）大剂量低张法ＩＶＵ碎石，（２）大剂量利尿法ＩＶＵ碎石，（３）逆行插管法ＥＳＷＬ，（４）联合法体外碎石。结果：结石排尽时间为１天～３周；肾功能改善为３月～２年，总有效率、结石排尽率与肾功能改善率分别为９９．６７％、９６．８０％、９４．３６％（Ｐ＜０．０１和Ｐ＜０．０５）。

A total of 3968 cases suffering from various types of ureteral calculiwere treated with ESWL under X-ray. The calculi of 42 cases(1.06%)were transparent and 135 cases(3.4%)semitransparent with low density.These cases were treated according to the pre-operative routine intravenous urography(IVU)and were divided intofour groups:(1)high dose hypotonic group,(2)high dose diuretic group,(3)The retrocatheterization group,and(4)combined therapy group.The results showed that the time for the stones to pass out completely varied from one dayto three weeks.Renal function was improved in three months to two years after the therapy. The total efficacy was99.6%.The rates of stones passed out completely and improvement of renal functlon were 96.80%and 94.36%re-spectively(P<0.01,P<0.05).
