Types Of Kidney Failure
There are two primary types of kidney
failure in humans. The first
occurs fairly suddenly and is called "acute renal failure". We'll talk
later about the causes of this condition. The second disease is more
insidious and occurs over time. It is called "chronic renal failure".
This type of kidney failure has causes of its own. The treatment for
both types of renal failure is roughly the same, with dialysis and
kidney transplant being the most common treatments.
One of the
most common causes of acute kidney failure, also called acute renal
failure, is the sudden loss of blood flow to the kidneys such as seen
in trauma, surgery, septic shock, heavy bleeding, burns or acute
dehydration. Infections can cause kidney failure, especially if they
cause the kidneys to be infected as well. More rarely, acute tubular
necrosis can cause the disease.
Sudden blockage of the kidneys can result in acute
kidney failure as does auto immune diseases and diseases that clot the
small blood vessels of the kidneys. Some of these conditions include
having a transfusion reaction, having malignant high blood pressure
(extremely high blood pressure), scleroderma or bleeding disorders of
pregnancy like an abrupted placenta or a placenta previa.
Symptoms of acute kidney failure are many. The most common symptoms are
a stoppage or slowing down of urine production, swelling of the ankles
and legs, fluid retention elsewhere in the body, decreased sensation of
the hands or feet, change in mental status, high blood pressure or
Chronic kidney failure affects the kidneys more slowly but results in
many of the same problems with the kidneys. In fact, it can occur over
several years. While there may be no symptoms in the beginning,
eventually the disease is as symptomatic as acute renal failure.
Symptoms occur when the kidney function is less than 10% of normal.
Chronic kidney failure occurs in 2 out of a thousand individuals in the
US. The most common causes of the disease are diabetes and high blood
pressure. These two diseases account for 65% of the cases of chronic
kidney failure. Other diseases are more unusual and include
glomerulonephritis, polycystic kidney disease, and conditions where
blockage or back flow of the urine occurs on a regular basis. Kidney
stones and recurrent infections can affect the condition as well as
recurrent infections in the kidney.
Symptoms of chronic kidney failure include weight
loss, nausea and
vomiting, fatigue, headache, frequent hiccups and generalized itching.
Eventually the symptoms are similar to acute kidney failure and one can
see poor urine output, nighttime urination, easy bruising, decreased
alertness (with drowsiness, lethargy, confusion or delirium), seizures,
muscle twitching, poor sensation of the hands or feet and high blood
Both chronic and acute kidney failure result in the build up of fluid
and waste products inside the body so that there is a buildup of
nitrogen wastes in the body as well as other waste products. Almost all
body systems are affected by kidney failure.
