      If the initial evaluation of the urinary tract raises the possibility of renal mass, one must decide what study or studies to perform to confirm or deny its presence. Radionuclide imaging has been the study of choice in this situation. Six cases are presented in which computed tomography definitively demonstrated that a suspicious renal mass represented normal renal parenchyma. Comparison with other renal imaging modalities is discussed.
