Clinicopathologic and treatment characteristics, pre‐ and post‐operative creatinine (Cr) values, and estimated glomerular filtration rates (eGFR) were recorded.

Post‐nephrectomy, median nadir eGFR was 44 ml/min, rebounding to 62 ml/min at median follow‐up of 50 months. Of 49 patients with preoperative eGFR ≥60 ml/min (CKD stage 1, 2), 51% preserved eGFR ≥60 postoperatively, whereas 49% progressed to CKD stage 3 (eGFR 30–59). Independent risk factors for progression of CKD stage were age and preoperative eGFR.
