To examine the indication of nephron sparing operations, we searched 31 nephrectomized kidneys with renal cell carcinoma for small associated lesions in the normal-appearing portion of these kidneys. The diameter of the predominant tumors was between 15 and 50 mm. The kidneys were serially sectioned at 5-mm intervals, and all sections were examined microscopically. Two of the 31 kidneys had a small renal cell carcinoma, and four had a small adenoma in the normal-appearing portion. We recommend that the nephron-sparing operation should be is performed limitedly and that radical nephrectomy is yet a standard operation in the presence of a normal contralateral kidney.
