Re: Prevalence of baseline chronic kidney disease in patients presenting with solid renal tumors

摘要

Objectives: To evaluate the prevalence of baseline chronic kidney disease (CKD) in a large cohort of patients presenting with renal masses to a tertiary care center, omparing serum creatinine (sCr) and estimated glomerular nitration rate (eGFR). sCr inadequately reflects renal function. eGFR and chronic kidney disease CKD stage are more clinically relevant parameters to reflect the risk of morbidity and mortality in patients after nephron loss. Methods: Using the prospectively maintained Fox Chase Kidney Cancer Database, we identified patients undergoing kidney surgery between January 2000 and May 2010. eGFR was calculated using the Modification of Diet in Renal Disease (MDRD) and the CKD-Epidemiology formulas.
