Abstract:
Introduction: The fractional excretion of sodium (FE Na) in urine has appeared as a helpful way to distinguish prerenal azotemia from acute tubular necrosis (ATN). Objectives: The urinary index of sodium has some limits. Lithium can be an additional careful indicator. The goal of our study was to assess the standards fractional excretion of sodium and lithium, (FE Na and FE Li) in distinguishing pre-renal azotemia (PRA) from ATN. Patients and Methods: Twenty-seven patients with prerenal azotemia, 25 patients with ATN and 20 healthy persons were included in this investigation. The plasma and ur

Abstract:
Blood urea nitrogen (BUN) rises disproportionately to serum creatinine in patients with prerenal azotemia whether due to impaired hemodynamics or excessive ureagenesis. To determine whether urinary urea nitrogen excretion rates can distinguish between these causes of hyperuremia we performed a cross-sectional observational study to compare urinary urea nitrogen excretion rates in a highly selected group of patients with prerenal azotemia. Patients who had stable serum creatinine levels, BUN: serum creatinine ratios exceeding 20:1, and progressive azotemia were identified from the hospital labo

Abstract:
The early distinction between prerenal azotemia, characterized by an avid proximal tubular sodium reabsorption, and ATN, in which proximal tubule function is depressed, remains an important but difficult clinical task. Indices of acute renal failure based on urinary sodium excretion may be helpful but have several limitations, among which is the use of diuretics. The effectiveness of the fractional excretion of uric acid (FEUA) and that of endogenous lithium (FELi) in the diagnosis of acute renal failure has been evaluated in an unselected group of 46 patients, 28 with prerenal azotemia and 18

Abstract:
Background/Aims. Acute kidney injury is a common problem for patients with cirrhosis and is associated with poor survival. We aimed to examine the association between type of acute kidney injury and 90-day mortality.Methods. Prospective cohort study at a major US liver transplant center. A nephrologist’s review of the urinary sediment was used in conjunction with the 2007 Ascites Club Criteria to stratify acute kidney injury into four groups: prerenal azotemia, hepatorenal syndrome, acute tubular necrosis, or other.Results. 120 participants with cirrhosis and acute kidney injury were analyzed.
