The life expectancy of someone who has end stage kidney failure depends on whether they go for dialysis treatment or doesn't do dialysis treatment.
If the person who has end stage kidney failure decides to not do dialysis then they may only live a week to a month with the end stage kidney failure.
If the person goes on dialysis then they can expect to live another 10 to 25 years or more depending on the persons current age and health as well.
Some people have been on dialysis treatments for 25 years or more and are leading normal lives even though they have to go in for dialysis treatment every few days.
Having end stage kidney failure doesn't always mean that you're gonna die soon as long as you get on dialysis treatment and don't miss the dialysis treatments you can live a long normal healthy and happy life.
