The renal failure index The renal failure index is used to compare the sodium clearance with the creatinine clearance. It is one of several indices that help in |
|
distinguishing prerenal azotemia from oliguric acute renal
failure. The renal failure index equation: RFI= Na+(U)*Cr(S)/Cr(U) Where: RFI=The renal failure index(%) Na+(U)=Urine Sodium(mEq/L) Cr(S)=Serum creatinine(mg/dl) Cr(U)=Urine creatinine(mg/dl) A renal failure index greater than 1 is consistent with oliguric acute renal failure; an index less than 1 is consistent with prerenal Azotemia.
