摘　　要：目的探讨磁共振水成像(MRU)对输尿管梗阻病变诊断的价值。方法回顾性分析经手术病理证实的28例输尿管梗阻患者的术前MRU及磁共振成像(MRI)检查资料。结果28例患者中泌尿系结石15例,输尿管炎性狭窄5例,输尿管肿瘤、膀胱癌各2例,肾结核、肾脓肿各2例。MRU能清楚显示梗阻的形态特征,定位准确率达100%。结论MRU结合常规MRI可以对输尿管梗阻病变作出准确的定位和辅助定性诊断。Objective To discuss magnetic resonance urography（MRU） in the diagnosis of ureteral obstruction value. Methods Retrospective analysis of the surgical pathology confirmed 28 cases of ureteral obstruction were performed in preoperative MRU and MRI examinations. Results Twenty-eight patients including 15 with urinary calculi, five with ureteral inflammatory stenosis and ureteral tumor, two with bladder cancer, two with renal tuberculosis and renal abscess. MRU clearly showed obstruction morphology and positioning accuracy rate was 100%. Conclusion MRU can be combined with conventional MRI lesions ureteral obstruction on the accurate positioning and assisted diagnosis.
