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 ...
Prerenal causes of AKI ("pre-renal azotemia") are those that decrease effective blood flow to the kidney and cause a decrease in the glomerular filtration rate (GFR). Both kidneys need to be affected as one kidney is still more than adequate for normal kidney function.
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 ...
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.
The original figure of 866 has been revised, as the survey initially included only inspections performed by state agencies and not those conducted by accredited private agencies. Using the expanded criteria, the average number of years since inspection is 3 ½, rather than 4 ½.

prerenal disease: the physiologic response to a decrease in kidney perfusion is an increase in sodium reabsorption to control hyponatremia, often caused by volume depletion or decrease in effective circulating volume (e.g. low output heart failure). above 2% [citation needed] or 3% [2] acute tubular necrosis or other kidney damage (postrenal ...
