Abstract

One patient who underwent radical nephrectomy for renal cell carcinoma participated in a follow up study of the contralateral hypoplastic renal function. Compensatory renal enlargement was demonstrated on follow excretory urogram. The enlargement was 12mm in length, 16mm in width. Immediately, postoperative renal function, GFR, was decreased to minimum value, 8.6 ml/min., but GFR of the remaining kidney was increased to maximal value, 37 ml/min. on post-op 5th day, and then decreased. After post-op 2.6 month the GFR was maintained as the level of 13-14 ml/min. Plasma BUN and creatinine was increased to maximum value, BUN 46.1 mg/dl Cr. 4.1mg/dl, on post-op 9th day and then decreased continuously. But these BUN and creatinine level were maintained as 29.3 mg/dl, 3.4 mg/dl on post-up 6th month. We present a case of this renal cell carcinoma with contralateral renal hypoplasia.
