Bilateral Renal Cell Carcinoma

Abstract
Bilateral renal cell carcinoma was diagnosed simultaneously in 6 patients and sequentially in 4 patients, 3-14 yr after the 1st tumor was removed by nephrectomy. Four patients treated conservatively with incomplete excision of the malignant disease are alive 18 mo.-14 yr after diagnosis. Experience suggests that a radical excision, requiring renal dialysis or transplantation, is seldom warranted.
