目的探讨输尿管中、下段结石冲击波碎石(SWL)治疗前静脉尿路造影(IVU)检查的价值.方法 112例病程在3个月、腹部平片(KUB)为不透x线和超声检查为非重度肾积水的单发输尿管中、下段结石患者随机分为两组,每组56例,IVU组SWL前行IVU检查,对照组SWL前不行IVU检查.观察SWL治疗后并发症、结石清除率.结果 IVU组有11例退出研究.对照组和IVU组结石清除率分别为89.3%(50/56)和88.9%(40/45),洽疗成功率分别为94.6%(53/56)和91.1%(41/45),并发症率分别为21.4%(12/56)和22.2%(10/45),组间比较差异无统计学意义(P＞0.05).结论病程在3个月内、KUB为不透X线和超声检查为非重度肾积水的单发输尿管中、下段结石患者,SWL治疗前无需IVU检查,这样可减少放射暴露、避免造影剂的毒副作用和节省医疗费用.

Objective To study the impact of preprocedure intravenous urography(IVU)on the outcome of shock wave Iithotripsy(SWL)for the middle and lower ureteral stones.Methods 112 patients with solitary radiopaque the middle and lower ureterat stones on plain radiographs and no severe hydronephrosis on ultrasonographic examination were divided randomly to two treatment groups.IVU group(n=56)had IVU before the start of SwL,whereas patients in the control group(n=56)underwent SWL without IVU.Postoperative success,stone-free rates and complications were evaluated in both groups.Results Eleven patients in the IVU group were excluded from the study.The SUCCESS rate[91.1%(41/45)in IVP group VS 94.6%(53/56)in control group],stone-free rate[88.9%(40/45)vs 89.3%(50/56)],and complication rate[22.2%(10/45)vs 21.4%(12/56)]were similar in two groups(P＞0.05).ConclusionIt is not necessary to obtain an IVU for patients who have solitary radiopaque the middle and lower calculi on plain radiographs with no severe hydronephrosis on ultrasonographic examination before scheduling them for SWL,thus minimizing the cost,avoiding exposure to contrast medium,and reducing radiation exposure.
