上尿路的移行细胞癌（TCC）比较少见。tcc和许多其他上尿路疾病的临床表现是非特异性的，大多数这些病变通常需要通过计算机断层扫描（CT）尿路造影进行评估。CT表现可分为乳头状瘤、浸润性乳头状瘤和弥漫性浸润性瘤。大多数上尿路tcc可根据特征性CT表现进行鉴别。然而，一些良性病变可能模仿不同类型的tcc，应考虑到鉴别诊断。这些病变包括子宫内膜异位症、肾源性腺瘤、足菌瘤、斑疹和与浸润性乳头状tcc相似的炎性假瘤；复杂尿石症、输尿管结石及输尿管肾盂连接处结石、慢性输尿管肾盂连接处梗阻合并感染、非典型肾盂肾炎、结核（类似弥漫性浸润性tcc）、纤维上皮性息肉（与乳头状tcc具有相同的CT表现）。对鉴别诊断有用的CT征象包括增强模式、病变位置、尿路硬化和尿壁增厚范围。三维重建图像对鉴别诊断是有用的。
The transitional cell carcinoma (TCC) of the upper urinary tract is relatively uncommon. The clinical presentation of TCCs and many other diseases of the upper urinary tract are nonspecific, and most of these lesions are usually necessary to be evaluated by computed tomography (CT) urography. CT appearances of TCCs can be classified as papillary, infiltrating papillary, and diffusely infiltrating tumor. Most TCCs of the upper urinary tract can be identified on the bases of characteristic CT appearances. However, some benign lesions may mimic different categories of TCCs and should be taken into account for differentiating diagnosis. These lesions include endometriosis, nephrogenic adenoma, mycetomas, malacoplakia, and inflammatory pseudotumor which are similar to infiltrating papillary TCCs; complex urolithiasis, passed stone of ureter and ureteropelvic junction, chronic ureteropelvic junction obstruction with superimposed infection, atypical pyelonephritis, and tuberculosis which mimic diffusely infiltrating TCCs, and fibroepithelial polyp which has the same CT appearances as papillary TCCs. The useful CT signs to make differential diagnosis involve enhanced pattern, location of lesion, induration of urinary tract, and range of thickening of urinary wall. The three-dimension (3D) reconstructed images is useful in making differential diagnosis.
