Kidneys are used to remove toxins from the blood. If the kidney function reduces than toxins in the body increase affecting various other body functions. Kidney failure itself does not cause death. Complications caused by it however lead to death of the patient if left untreated. Cardiovascular {heart failure} is the most common cause of death with individuals having kidney failure. Other causes are infection, septicemia, extra. Dialysis or kidney transplant is needed to avoid complications.

The exact time of death is difficult to comment as it is difficult to predict the condition of ones heart function or to know how an infection will occur or progress. However if more than 90 percent of kidney failure {no urine is produced} occurs than individual can not survive more than 2 to 3 weeks.

Good luck

How fast do the kidneys shut down, is it a gradual or an accelerating process and is it from the time the kidney failure hits 90% that the 2-3 weeks mentioned above commences?

Expert:  Ken replied 4 years ago.

An individual can live for many years if the kidney function is more than 10 percent. The kidney function deteriorates due to varied causes - hypertension/ diabetes/ atherosclerosis/ low blood flow to kidneys/ ageing.

Once the kidney function goes above 90 percent than deterioration accelerates.
