目的 :提高原发性输尿管癌的CT诊断与鉴别诊断水平。材料与方法 :回顾性分析 10例原发性输尿管癌病人的CT图像资料。男 8例 ,女 2例 ,平均年龄 63 5岁 ,均为移行上皮细胞癌。结果 :8例平扫时显示软组织肿块。增强后均可见输尿管管腔狭窄 ,局限性管壁增厚和充盈缺损 ,所有病例肾盂和梗阻上段输尿管不同程度扩张积水。结论 :选择合适的扫描区域和方法 ,CT对原发性输尿管癌的诊断较为容易 ,一般可明确诊断 ,并能为肿瘤分期提供依据。 Objective: To improve the diagnosis and differential diagnosis of primary ureteral cancer. Materials and Methods: CT images of 10 patients with primary ureteral carcinoma were retrospectively analyzed. 8 males and 2 females, average age 63 5 years old, are transitional cell carcinoma. Results: 8 cases of soft tissue mass scan. Enhanced ureter stenosis can be seen after the limitations of the wall thickening and filling defects in all cases of renal pelvis and obstruction upper ureteral expansion of water to varying degrees. Conclusion: Choosing the appropriate scan area and method, CT diagnosis of primary ureteral cancer is relatively easy, generally clear diagnosis, and can provide the basis for tumor staging.
