Kidney failure patients on lifelong dialysis have an average life expectancy of five to 10 years, according to the National Kidney Foundation. The prognosis for acute kidney failure is heavily dependent on whether or not the failure is due to kidney tissue damage, according to eMedicineHealth.
Patients with undamaged tissue often make full recoveries. The in-hospital mortality rate for acute kidney failure is 40 to 50 percent. Approximately 12.5 percent of acute kidney failure patients require dialysis after one to 10 years, and 19 to 31 percent suffer from chronic kidney disease. Intensive care kidney failure patients on dialysis have a mortality rate of 70 to 80 percent, according to eMedicineHealth.
