Azotemia has three classifications, depending on its causative origin: prerenal azotemia, renal azotemia, and postrenal azotemia. [2] Measurements of urea and creatinine (Cr) in the blood are used to assess renal function. For historical reasons, the lab test measuring urea is known as "blood urea nitrogen" (BUN) in the US. The BUN:Cr ratio is ...
Acute kidney injury (AKI), previously called acute renal failure (ARF), [1] [2] is a sudden decrease in kidney function that develops within seven days, [3] as shown by an increase in serum creatinine or a decrease in urine output, or both.
Prerenal azotemia can be caused by decreased blood flow through the kidneys (e.g. low blood pressure, congestive heart failure, shock, bleeding, dehydration) or by increased production of urea in the liver via a high protein diet or increased protein catabolism (e.g. stress, fever, major illness, corticosteroid therapy, or gastrointestinal ...
Fractional excretion of other substances can be measured to determine kidney clearance including urea, uric acid, and lithium. These can be used in patients undergoing diuretic therapy, since diuretics induce a natriuresis. Thus, the urinary sodium concentration and FE Na may be higher in patients receiving diuretics in spite of prerenal ...
Prerenal acute kidney injury Acute kidney injury, or AKI, is when the kidney isn’t functioning at 100% and that decrease in function usually over a few days. Actually, AKI used to be known as acute renal failure, or ARF, but AKI is a broader term that also includes subtle decreases in kidney function.

[8] [9] If the condition is allowed to progress without treatment, it can eventually lead to azotemia and uremic symptoms. [9] This constellation of symptoms contrasts with the classical presentation of nephrotic syndrome (excessive proteinuria >3.5 g/day, low plasma albumin levels (hypoalbuminemia) <3 g/L, generalized edema, and hyperlipidemia ...
