| Abstract: | A 69-year-old man visited our clinic with the chief complaint of macroscopic hematuria. On CT scanning and renal arteriography, a round tumor about 3 cm in diameter on the frontlateral phase of the left kidney and another tumor ranging from the upper pole to the center of the right kidney were recognized. Under the diagnosis of bilateral renal tumor, first in November 1980 left partial nephrectomy was performed to extirpate the tumor. Then, upon recovery from postoperative transient renal hypofunction, right nephrectomy was performed in January 1981. After the operation renal hypofunction was noted again, but in March of the same year he was discharged as his creatinine value was stabilized to 3 approximately 4 mg/dl. Histopathologically the tumor of the left kidney was clear cell subtype and that of the right kidney was granular cell subtype of renal cell carcinoma. He has been followed up under administration of PSK and CQ in the outpatient clinic. As of January, 1985 he is well without recurrence or metastasis. |
