目的探讨输尿管结石冲击波碎石(SWL)治疗前是否必须行静脉尿路造影(IVU)检查.方法选择212例病程为3个月、腹部平片(KUB)为不透X光和超声检查为非重度肾积水的单发输尿管结石患者随机两组,每组106例,IVU组SWL前行IVU检查,对照组SWL前不行IVU.观察SWL治疗后并发症、结石清除率.结果 IVU组有18例退出研究.对照组和IVU组结石清除率分别为87.7%(93/106)和86.4%(76/88);治疗成功率分别为94.3%(100/106)和93.2%(82/88);并发症率23.6%(25/106)和25%(22/88),组问比较差异无统计学意义(P>0.05).结论病程在3月内、KUB为不透X光和超声检查为非重度肾积水的单发输尿管患者,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 determine whether intravenous urography(IVU) is a prerequisite for shock wave lithotripsy(SWL) of ureteral calculi. Methods Two hundred twelve patients with solitary radiopaque ure-teral stones on plain radiographs and no severe hydronephrosis on uhrasonographic examination and whose illness duration whithin 3 months were allocated randomly to two treatment groups. IVU group (n = 106)had IV U before the start of SWL,whereas patients in the control group(n = 106)underwent SWL without]VU. Postoperative suc-cess, stone-flee rates and complications were evaluated in both groups. Results Eighteen patients in the IVU group were excluded from the study. The success rate [93.2% (82/88) in IVP group vs 94. 3% (100/106) in control group], stone-free rate [86.4% (76/88) vs87.7% (93/106)], and complication rate [25% (22/88) vs23.6% (25/106)] were similar in the two groups (P > 0.05). Conclusion It is not necessary to obtain an IVU for patients who have solitary radiopaque ureteral calculi on plain radiographs with no severe hydronephrosis on ultrasonographic examination and whose illness duration whithin 3 months before scheduling them for SWL, thus minimizing the cost, avoiding exposure to contrast medium, and reducing radiation exposure.
