摘　　要：目的 :探讨输尿管结石的静脉尿路造影 (IVU)表现。方法 :回顾性分析 65例输尿管结石 (直径 <10mm)患者的临床和IVU表现。结果 :所有病例均经治疗或输尿管镜取石证实。结石 5 .1～ 10mm者 3 4例 ;≤ 5mm者 3 1例 ,结石易停留在输尿管生理狭窄部位 ,多为卵圆形。结石近侧输尿管轻度扩张者 5 9例 ,肾盂肾盏扩张积水者 3 9例。结论 :IVU结合平片能很好地显示尿路的形态 ,具有易于发现结石、定位准确等优点 。Objective:To evaluate the findings of intravenous urography (IVU) in ureter stones.Methods:Clinical and IVU findings of 65 patients with ureter stone less than 10 mm in diameter were analyzed retrospectively.Results:The diagnosis of all of the cases were verified by surgery or through ureterolithotriptoscopy.The size of stones was 5.1～10mm in 34 cases, and ≤5mm in 31 case. The incarcerating site of ureter stone was usually the physiologic constriction. The form of stones was mostly oval shaped. There was mild dilatation of the ureter proximal to the stone (n=59) and concomitant hydrocalyx and hydronephrosis were seen in 39 cases.Conclusion:The use of IVU provides a good method for well demonstration of urinary system and easy identification and location of the ureter stone.Combined with plain radiography,IVU plays a leading role in the evaluation of urinary calculi.
