Kidney failure occurs when the kidneys lose their ability to
function. To treat kidney failure effectively, it is important to know whether
kidney disease has developed suddenly (acute) or over the long term (chronic).
Many conditions, diseases, and medicines can create situations that lead to
acute and chronic kidney disease. Acute renal failure is more commonly
reversible than chronic kidney failure.
The presence or lack of symptoms may help your doctor determine
whether acute renal failure or chronic kidney disease is present.
Most cases of acute renal failure occur in people who are already in
the hospital for other reasons. In these people, acute renal failure is usually
diagnosed when routine tests show a sudden increase in
blood urea nitrogen (BUN) levels. A buildup of these
waste products in the blood points to a loss of kidney function. Your doctor
will compare these levels to previous tests to find out if kidney disease is
acute or chronic.
ultrasound of the kidneys also may help determine
whether kidney problems are acute or chronic. Normal-sized kidneys may be
present in either condition, but when both kidneys are smaller than normal,
chronic kidney disease is usually the problem.
