The records of 65 consecutive patients discharged from the hospital with a diagnosis of primary parenchymal neoplasm of the kidney were reviewed. Four of the 65 patients had neoplasms which were not detected by excretory urography. The 4 undetected lesions included 3 renal cell carcinomas and 1 oncocytoma. All of these lesions projected from the anterior or posterior surface of the kidney, and all 4 were clearly demonstrated by computed tomography. Normal findings on an excretory urogram do not completely exclude a neoplasm of the kidney. When there is strong clinical suspicion of a renal neoplasm, computed tomography should be the initial examination or should be done even if the urogram has shown normal findings.
回顾了65例出院诊断为原发性肾实质肿瘤的连续患者的病历。65例患者中有4例肿瘤在排泄性尿路造影中未被检测到。这4例未被检测到的病变包括3例肾细胞癌和1例嗜酸细胞瘤。所有这些病变均从肾脏的前表面或后表面突出，并且这4例病变在计算机断层扫描中均清晰显示。排泄性尿路造影的正常结果并不能完全排除肾肿瘤。当临床上高度怀疑肾肿瘤时，计算机断层扫描应作为初始检查，即使尿路造影显示正常结果也应进行该项检查。
