逆行插管与静脉造影定位ESWL治疗上尿路阴性结石的比较

为探讨不同部位上尿路阴性结石定位方法的选择，对９８例上尿路阴性结石患者采用大剂量静脉尿路造影（ＩＶＵ）和逆行插管（ＲＧＰ）定位法行体外冲击波碎石术（ＥＳＷＬ），并根据其疗效进行比较。结果：２０例肾阴性结石中，８例行ＩＶＵ定位下ＥＳＷＬ碎石，治愈率为１２．５％；１２例行ＲＧＰ定位下ＥＳＷＬ碎石，治愈率为８．３％；认为对此类患者不宜行Ｘ线定位碎石。５８例输尿管上、中段阴性结石中，２８例行ＩＶＵ定位碎石

A comparative study on opaque stones treated with extracorporeal shock wave lithotripsy using retrograde urography and intravenous urography location in upper urinary tract

In order to select appropriate methods to locate opaque stones of upper urinary tract, 98 patients with opaque stones of upper urinary tract were treated with extracorporeal shock wave lithotripsy (ESWL) using retrograde urography (RGU) and intravenous urography (IVU) location. Of 20 cases of renal calculi, 8 cases were treated with ESWL using IVU location with 12. 5 % curative rate, 12 cases using RGU location with 8. 3% curative rate. It was considered that this kind of stone was not suitable for ESWL using X-ray location. Of 58 cases of upper and middle ureter stones,28 cases were treated with ESWL using IVU location with 71. 4% curative rate,using IVU in combination With RGU location with 89. 3% curative rate. It was suggested that this kind of stone was suitable for ESWL using IVU location firstly and replacing by RGU location if failed. Of 20 cases of lower ureter stones,8 cases were treated with ESWL using IVU location with 12. 5% curative rate, 12 cases using RGU location with 58.3% curative rate. It was concluded that this kind of stone was suitable for ESWL using RGU location firstly.
