Preoperative Chronic Kidney Disease Status is an Independent Prognostic Factor in Patients with Renal Cell Carcinoma

Preoperative chronic kidney disease (CKD) status may affect disease outcomes in patients with renal cell carcinoma (RCC). This study evaluated the influence of preoperative CKD status on clinicopathological features and prognosis in patients with RCC. Between 1999 and 2011, a total of 1855 patients underwent radical nephrectomy at various centers throughout Korea. Of these patients, 1655 had an estimated glomerular filtration rate (eGFR) ≥60 ml/min/1.73 m2 (non-CKD group) and 200 patients had an eGFR ≥30 but
