RENAL FAILURE
i. Acute renal failure
ii. Chronic renal failure
, ACUTE RENAL FAILURE (ARF)
• ARF is an abrupt decrease in renal function
sufficient to result in retention of
nitrogenous waste (e.g. BUN and creatinine)
in the body. The hallmark of ARF is
progressive azotemia caused by the
accumulation of the nitrogenous end-
products of metabolism.
, • This accumulation is accompanied by:
• Metabolic acidosis
• Hyperkalemia
• Disturbances of body fluid balance, and
effects on many other organ systems.
