摘　　要：目的:评价MRI在原发性输尿管恶性肿瘤中应用价值。方法:回顾分析了14例经手术病理和窥镜下活检证实的原发性输尿管恶性肿瘤患者的临床和MRI资料。结果:原发性输尿管恶性肿瘤主要临床表现为:腰背部痛和无痛性血尿。发病部位为上段3例,中段1例,盆段10例。盆段输尿管易受累,占71.4%(10/14)。MRI轴位像:梗阻端可见结节,不见管壁和可见结节,部分见管壁者为具有特异性,本组占85.7%(12/14)。MRU:以梗阻端呈截头状、杵状、钢笔尖状形态较具有诊断价值,本组占71.4%(10/14)。结论:在非创伤性的诊断方法中,以MR最具优势;对高龄、血尿患者,应行MRI检查,对于肯定和排除原发性输尿管恶性肿瘤有一定价值。Objective：To evaluate the clinical using value of MRI in primary ureteral malignant tumor.Methods：MRI and clinical material of 14 patients with primary ureteral malignant tumor.which was proved by operation-pathology and biopsy under endoscope were analyzed retrospectivelv.Results：The main clinical finding of the primary malignant were painless hematuria.pain of lumbar back.The location of tumor included upper portion（n=3）.Mid portion（n=1）.pelvis portion（n=10）.pelvis portion was involved early.it was occupied 71.4%（10/14）.Nodule could beseen on axial imaging of MRI,but wall of tube was not seen.and nodule could be seen.the part of wall o ftube could be seen.these were occupied 85.7%（12/14）.and relatively specificness.The most value of diagnosis is that the spot of the obstruction was showed interruption.drumstick and top of the steel＇s pen on MRU.there were occupied 71.4%（10/14）.Conclusion： MRI has advantage in the no injuring diagnosis method.it should be sued for patients who are older or had hematuria,have value of diagnosis for confirming or excluding primary ureteraI malignant tumor.
