Fractional excretion of sodium and fractional excretion of urea in differentiating prerenal from renal azotemia complicating circulatory shock

چکیده
Methods Both serum FENa & FEurea were measured in 40 patients (pts) with acute kidney injury (AKI) complicating circulatory shock during their stay in ICU. All patients were divided into 26 pts (mean: 60.0 ± 15.15 years) with prerenal azotemia (group-1) and 14 pts (mean: 56.29 ± 19.5 years) with renal azotemia (group-2). Group-1 was subdivided into 12 pts (group-1a) who didn’t receive diuretics 24 hours before the sampling process and 14 pts (group-1b) who received diuretics during their stay in ICU. Acute kidney injury was diagnosed according to the RIFLE-criteria (Risk, Injury, Failure, Loss and End-stage Kidney) in oliguric patients.

Traditional urinary biomarkers in the assessment of hospital-acquired AKI.
Traditional biomarkers, such as urine chemistries and urine microscopic elements, are used in the diagnosis and care of patients with AKI. Urine chemistries, such as fractional excretion of sodium and fractional excretion of urea, are useful for differentiating prerenal AKI from acute tubular necrosis only in select patients. Urine microscopy using a quantitative evaluation of the urine sedimen...
متن کاملFinding the cause of acute kidney injury: which index of fractional excretion is better?
The fractional excretion of urea (FEU) is a useful index for differentiating the main categories of causes of acute kidney injury, ie, prerenal causes and intrinsic causes. It may be used in preference to the more widely used fractional excretion of sodium (FENa) in situations in which the validity of the latter is limited, such as in patients taking a diuretic.
متن کاملEvaluating the effect of short ischemic periods on subsequent rat renal ischemic injury
Introduction: Using brief episodes of ischemia and reperfusion (IR) prior to a more sustained IR insult – ischemic preconditioning (IPC) – can reduce IR injury of the heart, brain and many other tissues. The purpose of present study was to investigate the effect of 2min ischemic periods on subsequent rat renal IR injury. Methods: Male rat's renal IR injury was investigated in a right nephrectom...
متن کاملRenal Fractional Excretion of Sodium in Relation to Arterial Blood Gas and Spirometric Parameters in Chronic Obstructive Pulmonary Disease
Introduction: Arterial gas derangement could change urinary sodium excretion in Chronic Obstructive Pulmonary Disease (COPD) patients.There are very few and conflicting data in regards to the measurement of fractional excretion of sodium in COPD patients. The main aim of this study was to assess the relationship between renal fractional excretion of sodium(FeNa) with arterial blood gas and spir...
متن کاملFractional excretion of uric acid as a predictor for saline responsiveness in long-term kidney transplant patients.
BACKGROUND/AIMS Subclinical hypovolemia may contribute to allograft dysfunction in long-term kidney transplant (KT) patients. In order to predict responsiveness to saline hydration, indices for tubular transport were investigated. METHODS Fifty-four clinically euvolemic long-term KT patients with recently aggravated azotemia were given intravenous hydration as follows: 0.9% saline 5 ml/kg ove...
