What is the average life expectancy for someone in end-stage renal failure on dialysis?

Dyalisis: It is 3-5 years if dyalisis is being done. Mortality rate for people on dialysis is 22%/year. That gives an average of 5 years.

Depends upon health: Very variable. Current medical literature quotes 22% annual mortality rate which suggests 5 year survival rate. However, younger and otherwise healthy subjects can live 10 -20 years on dialysis. Kidney transplantation has a much better prognosis if and when there is choice. Some subjects only need tdialysis on temporary basis on temporary and recover kidney function. Others are 2 sick for transpl.

Depends: The average life expectancy is 5-7 years on average. Put young patients tend to leave longer than very old patients and healthier more compliant patients tend to do better than those than skip dialysis very often. So don't let the average numbers define overall prognosis. Also once a patient is esrd they can be listed for transplant which has a higher life expectancy than dialysis patients.
