To investigate whether the postoperative renal function in patients with renal cell carcinoma can be predicted by the preoperative serum creatinine (sCr) and the renal parenchymal volume (RPV) estimated by the preoperative 3-dimensional image reconstruction. Seventy-six and 26 patients who underwent radical and partial nephrectomy were subjected to this study. The postoperative RPVs were estimated from the preoperative CT or MRI, and were compared with the RPVs estimated from the postoperative imaging. The postoperative creatinine clearance (Ccr) was predicted by the preoperative Ccr calculated from the sCr level and by the ratio of the postoperative/preoperative RPV. The predicted postoperative Ccr significantly correlated with the actually measured postoperative Ccr. Prediction of the postoperative Ccr, using the preoperative sCr and the preoperative diagnostic imaging, is a simple and reliable method.
