Kidney Failure

Medical Definition: The inability of a kidney to excrete metabolites at normal plasma levels under conditions of normal loading, or the inability to retain electrolytes under conditions of normal intake. In the acute form (KIDNEY FAILURE, ACUTE), it is marked by uremia and usually by oliguria or anuria, with hyperkalemia and pulmonary edema. The chronic form (KIDNEY FAILURE, CHRONIC) is irreversible and requires hemodialysis.
Guide Notes: for renal failure unspecified as "acute" (KIDNEY FAILURE, ACUTE) or "chronic" (KIDNEY FAILURE, CHRONIC) but check text for clues at those annotations

Kidney Failure Categories.
Canadian Medical Guide Definition Kidney Failure, Acute - A clinical syndrome characterized by a sudden decrease in glomerular filtration rate, often to values of less than 1 to 2 ml per minute. It is usually associated with oliguria (urine volumes of less than 400 ml per day) and is 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.
Canadian Medical Guide Definition Kidney Failure, Chronic - An irreversible and usually progressive reduction in renal function in which both kidneys have been damaged by a variety of diseases to the extent that they are unable to adequately remove the metabolic products from the blood and regulate the body's electrolyte composition and acid-base balance. Chronic kidney failure requires HEMODIALYSIS or surgery, usually KIDNEY TRANSPLANTATION.
