Kidney Failure, Acute (C0022660)

Definition (NCI_CTCAE) A disorder characterized by the acute loss of renal function and is traditionally classified as pre-renal (low blood flow into kidney), renal (kidney damage) and post-renal causes (ureteral or bladder outflow obstruction).
Definition (NCI) Sudden and sustained deterioration of the kidney function characterized by decreased glomerular filtration rate, increased serum creatinine or oliguria.
Definition (CSP) clinical syndrome characterized by a sudden decrease in glomerular filtration rate, usually associated with oliguria and always associated with biochemical consequences of the reduction in glomerular filtration rate such as a rise in blood urea nitrogen (BUN) and serum creatinine concentrations.

Uremia (C0041948)

Definition (CSP) excess in the blood of urea, creatinine and other nitrogenous end products of protein and aminoacid metabolism; also, the constellation of signs and symptoms of chronic renal failure.
Definition (MSH) A clinical syndrome associated with the retention of renal waste products or uremic toxins in the blood. It is usually the result of RENAL INSUFFICIENCY. Most uremic toxins are end products of protein or nitrogen CATABOLISM, such as UREA or CREATININE. Severe uremia can lead to multiple organ dysfunctions with a constellation of symptoms.
