Abstract

Four patients with malignant renal masses showed no abnormality on excretory urograms with tomography. Of the four lesions, two were primary renal cell carcinomas, one was a metastatic focus from a contralateral renal cell carcinoma, and one was a metastatic lesion from rectal adenocarcinoma. A normal excretory urogram should not be considered sufficient to exclude a clinically suspected malignant renal mass. In such an instance, diagnostic evaluation should be pursued using a method capable of topographic anatomic display, such as computed tomography or sonography.
