摘　　要：目的探讨磁共振尿路造影(MRU)对重复肾输尿管畸形的诊断应用价值研究。方法对本院2010年1月-2015年1月重复肾输尿管畸形的符合要求的40例患者为研究对象,从MRU对重复肾输尿管畸形疾病的诊断准确率、MRU技术具体运用、MRU的技术优势等阐述MRU对重复肾输尿管畸形患者的诊断应用价值研究。结果 40例患者经MRU检查后,MRU诊断结果显示重复肾患者为40例,MRU结果与患者手术结果相比,MRU的确诊率为100%,其中重复肾单侧病变患者22例,双侧病变患者18例。MRI平扫BTFE序列与SPAIR序列图像清晰,能有效对肾功能进行准确评价;MRU的MIP技术与多角度立体显示重复肾、输尿管的空间解剖结构,全面性佳。结论磁共振尿路造影(MRU)禁忌症少,无需造影剂且无辐射,对重复肾输尿管畸形诊断率高,图像显示立体,为临床手术提供具体影像学指导资料。Objective To investigate the clinic application value of MRU on duplex kidney. Methods 40 cases with duplex kidney in our hospital from January 2010 to January 2015 were selected. Observe the value from correct diagnosis rate of MRU, MRU application and MRU technological superiority.Results 40 cases after MRU, results showed 40 cases with duplex kidney. Compared with surgery results, diagnose rate of MR.U was 100%, 22 cases with unilateral lesion and 18 cases with bilateral lesions. In MRI scan, BTFE and SPAIP, had clear image, it can effectively evaluate renal fnnction. MIP of MR.U can show space anatomical structure of duplex kidney and ureter. Conclusion MP, U has shorter contraindication, need no contrast agent and nonradiative. It has higher diagnostic rate on duplex kidney and provide guide information on clinic surgery.
