摘　　要：目的分析输尿管移行上皮细胞癌的MRU表现,探讨MRU对输尿管移行上皮细胞癌的诊断价值.方法回顾性分析11例经手术病理确诊的输尿管移行细胞癌的MRU表现,结合文献分析病变部位、形态、范围和周围组织的改变.结果11例病例中病变位于上段的1例,中段的2例,下段的8例,11例均有输尿管梗阻,梗阻上段输尿管均有不同程度的扩张和肾盂积水;5例病变呈结节状,分叶状,不规则充盈缺损,4例病变沿输尿管壁呈侵润性生长,其中2例腹主动脉旁和肾门旁淋巴结增大,2例呈管腔内圆柱形软组织,未突破肌层及输尿管周围脂肪,境界尚清.MRU对输尿管癌的诊断敏感性及特异性分别为100%(11/11)和81.8%(9/11).结论MRU能明确输尿管癌的病变部位、形态、范围和周围组织的改变,但是定性诊断需要进一步的研究和探讨.Objective To study the feature of MRU in ureter transitional cell carcinoma, to discuss the diagnostic value of MRU in tranlitional cell carcinoma of ureter. Methods We retrospectively analyzed the MRU of 11 cases of ureteral transitional cell carcinoma confirmed by surgery and pathology. Combined with literature review, we also analyzed the shape, scope and surrounding tissue changes of lesion. Results One lesion was located at the upper portion of the ureter, 2 at middle portion and 8 at lower portion. Each case presented urinary obstruction, distention and uretal hydrocele; 5 showed nodular shape irregular, 4 showed infitrative growth in location, 2 showed enlargement of lymph nodes in surrounding of abdominal and renal major artery out in 4 cases, 2 showed cylindrical intraluminal soft tissue, muscle of ureters did not break through the surrounding fat, state clearly. The diagnostic sensitivity and specificity of MRU in ureteral cancer 100% （11/11） and 81.81% （9/11）. Cnclusion The location, the shape, the spectrum of the tumor and change of surrounding tissue were clear cured in MRU, confirmation of the diagnosis need but further research the.
