It is very hard to find a kidney transplant. In some countries it can take several years before you can get a transplant.
If you have kidney failure then you will need to do dialysis or have a kidney transplant. If treatment is not received, the build up of toxins is fatal.
Hemodialysis
Kidney failure results in death in a few days, usually less than a week, unless the person receives a kidney transplant or is put on a dialysis machine.
Kidney failure. This may sometimes be reversed, and patients can be assisted by dialysis for a time, but complete failure needs a transplant.
Chronic kidney disease is often treated with dialysis. It is manageable but not reversible.
it doesn't always have to be permanent because people on dialysis machines can get kidney transplants, not just people on the dialysis get kidney transplants but people who are on the waiting list can also get a kidney transplant.
if your kidneys fail completely, then you can go on a transplant list and get a kidney transplant if your kidneys are failing the doctors will put you on dialysis ... trying to keep your blood clean... eventually your kidneys will fail and then you will get a transplant
There are only 2: 1) Dialysis - either hemodialysis or pertitoneal. 2) Kidney Transplant
There aren't really any advantages over a kidney transplant, as dialysis is used to keep patients alive while they wait for a transplant. Patients are always on the waiting list for a transplant, which shows that there isn't really any benefit.
Kidney failure and kidney rejection can still remain after kidney transplant.
People who have kidney failure, which is when 90% or more of the kidneys do not work, must be on dialysis. When kidneys fail the body cant cleanse the body of waste. The persons blood will become toxic and the person will die without dialysis or a kidney transplant. That's just with kidney failure. Of course you can live with only one kidney. Say you only had one kidney, that one kidney would have to be over 50% damaged before a person would possibly need to be on dialysis. To simply answer your question, you could have no problems with a damaged kidney, but failed kidneys will cause death.
Because kidney dialysis, although effective, is not a long term solution due to the huge amount of time it requires. Dialysis is just not convenient - for a patient with very little kidney function, dialysis it takes up a vast amount of time each week, is not possible to do on holidays, and women cannot have children whist on dialysis. Whereas a kidney transplant is far more portable than a dialysis machine, does allow the possibility of children, and does not require a vast amount of maintenance per week. Although it does require daily medication and periodic check-ups, for most people it is still the "easier" long-term solution, compared to dialysis.
