Acute Renal Failure (ARF) and Acute Tubular Necrosis (ATN)īeside the index result discussed above, there are clinical findings that suggest either the prerenal (volume depletion, existing CHF - congestive heart failure, severe liver disease, edema) or the postrenal causes (palpable bladder, hydronephrotic kidneys, enlarged prostate, renal calculi).ĪRF is characterized by azotemia, supported or not by oliguria and that progresses in a matter of hours or days.Įarly recognition of the causes of ARF is essential in the quick initiation of treatment as this is a condition often affecting hospitalized patients and carries high morbidity and mortality rates. The following is a list with the most common risk factors for kidney disease: The main areas of focus within renal function tests include BUN (blood urea nitrogen), Creatinine, fractional excretion of sodium / urea and uric acid. This is a renal function test aimed at assessing the function of the kidneys and at revealing whether the cause of acute failure is renal or prerenal:īy differentiating between prerenal azotemia and oliguric acute renal failure, this index is used in the first stages of diagnosis alongside other clinical determinations. Increased creatinine levels are indicative of: ■ Urine Creatinine – creatinine levels that escape the filtration process and are excreted through urine, normal range between 40 – 120 mg/dL. ■ Serum Creatinine – breakdown product in the metabolism of the muscles and certain tissues, filtered by the glomerulus, with a normal range between 0.6 and 1.3 mg/dL. With a normal low of 25 and a normal high of 150 mEq/dL. ■ Urine sodium – measured in miliEquivalents per dL. This Renal Failure Index (RFI) calculator provides three fields to input the clinical determinations required, one measured in mEq/L and the other two measured in mg/dL as explained below: This is a health tool that determines the RFI value in patients who are suspect of acute kidney failure due to acute tubular necrosis. How does this Renal Failure Index (RFI) calculator for acute tubular necrosis work?
