Urothelial carcinoma (UC) is the fourth most frequent tumor in Western countries and upper tract urothelial carcinoma (UTUC), affecting pyelocaliceal cavities and ureter, accounts for 5-10% of all UCs. Computed tomography urography (CTU) is now considered the imaging modality of choice for diagnosis and staging of UTUC, guiding disease management. Although its specificity is very high, both benign and malignant diseases could mimic UTUCs and therefore have to be well-known to avoid misdiagnosis. We describe CTU findings of upper urinary tract carcinoma, features that influence disease management, and possible differential diagnosis.
尿路上皮癌（UC）是西方国家第四常见的肿瘤，而上尿路尿路上皮癌（UTUC）累及肾盂肾盏和输尿管，占所有UC的5%-10%。计算机断层扫描尿路造影（CTU）现在被认为是UTUC诊断和分期的首选成像方式，可指导疾病管理。尽管其特异性很高，但良性和恶性疾病都可能模仿UTUC，因此必须充分了解以避免误诊。我们描述了上尿路癌的CTU表现、影响疾病管理的特征以及可能的鉴别诊断。
