目的 :探讨尿路造影期间合用CT平扫诊断输尿管扩张原因的价值。方法 :对 12例尿路造影中出现不同形式的输尿管扩张再进行CT平扫并分析。结果 :1例为腔静脉自后绕行输尿管致狭窄 ,1例示不规则软组织影系残段输尿管癌 ,10例为输尿管结石影。结论 :尿路造影期间合用CT平扫对诊断输尿管扩张的原因是一种有效的检查
Objective: To evaluate the value of computed tomography (CT) in the diagnosis of ureteral dilatation during urography. Methods: 12 cases of urography appeared in different forms of ureteral dilatation before CT scan and analysis. Results: One case was urethral stricture caused by retrograde vena cava, one case showed ureteral carcinoma of stump with irregular soft tissue shadow, and 10 cases had ureteral calculi. CONCLUSIONS: CT scanning during urography is the most effective way to diagnose ureteral dilatation
