The ability of excretory urography and computerized tomography to detect renal masses was compared in 120 consecutive cases. Computerized tomography consistently provided more information than excretory urography, usually was able to distinguish renal tumors from cysts and provided additional useful information regarding staging of renal neoplasms and the presence of unsuspected associated pathological conditions.
对连续120例患者进行了排泄性尿路造影和计算机断层扫描检测肾脏肿块能力的比较。计算机断层扫描始终比排泄性尿路造影提供更多信息，通常能够区分肾肿瘤和囊肿，并提供有关肾肿瘤分期及未被怀疑的相关病理状况存在与否的额外有用信息。
