ARF is a serious condition and its complications can lead to death. It may resolve in time and sometimes within days. Recovery also depends on the underlying cause and the treatment given. Mortality is highest in surgical patients and the leading causes of death are infection, bleeding of the digestive tract and fluid/electrolyte disturbances. Children tend to have a better chance of regaining their kidney function than adults. Only a minority of patients with ARF are left with permanent residual kidney damage.
