Fourteen cases of primary squamous cell carcinoma (SCC) originating in the uroepithelium were studied with computed tomography (CT). Nine cases were of vesical origin, three were of renal pelvic origin, and two were of ureteral origin. CT scans of eight of the 14 cases, including four cases of vesical origin and four cases of renal pelvic or ureteral origin, demonstrated predominantly extraluminal extension with invasion into adjacent organs or the renal parenchyma. CT scans of the remaining six cases showed almost equal extra- and intraluminal tumor growth and no predominantly intraluminal extension. An associated urinary stone was demonstrated in four of the five cases of SCC of renal pelvic or ureteral origin. Two of these cases were diagnosed as urinary stones before CT was performed. Eight of the nine cases of SCC of vesical origin and four of the five cases of SCC of renal pelvic or ureteral origin were correctly staged with the aid of CT.
对14例起源于尿路上皮的原发性鳞状细胞癌（SCC）进行了计算机断层扫描（CT）研究。其中9例起源于膀胱，3例起源于肾盂，2例起源于输尿管。14例中的8例CT扫描，包括4例膀胱起源和4例肾盂或输尿管起源，显示主要为腔外扩展并侵犯相邻器官或肾实质。其余6例的CT扫描显示腔内和腔外肿瘤生长几乎相等，无主要的腔内扩展。在5例肾盂或输尿管起源的SCC中，有4例发现合并尿路结石。其中2例在进行CT检查前被诊断为尿路结石。9例膀胱起源的SCC中有8例以及5例肾盂或输尿管起源的SCC中有4例借助CT进行了正确分期。
