To evaluate the computed tomography (CT) semiological criteria used in the diagnosis of transitional cell carcinoma of the upper urinary tract.
26 patients with transitional cell carcinoma of the upper urinary tract underwent preoperative CT. In all cases nephroureterectomy was performed and CT and histopathologic findings were compared.
16 tumors were infiltrative and 10 tumors were sessile. The smallest tumour had 7 mm diameter and the largest one 13 cm. Associated focal hydronephrosis appeared in 11 cases and diffuse hydronephrosis in 7 cases. The vast majority of these tumors (69.23%) had a 21 to 50 Hounsfield Units enhancement.
CT is a powerful tool to diagnose transitional cell carcinoma of the upper urinary tract when data acquired in intravenous urography and echography are equivocal.
评估用于诊断上尿路移行细胞癌的计算机断层扫描（CT）影像学标准。
26例上尿路移行细胞癌患者术前行CT检查。所有病例均行肾输尿管切除术，并比较CT与组织病理学检查结果。
16例肿瘤为浸润性，10例为无蒂。最小肿瘤直径7mm，最大肿瘤直径13cm。11例出现相关局灶性肾积水，7例出现弥漫性肾积水。这些肿瘤绝大多数（69.23%）增强扫描后Hounsfield单位为21至50。
当静脉肾盂造影和超声检查获得的数据不明确时，CT是诊断上尿路移行细胞癌的有力工具。
