@Animandel - There are some benefits to having a kidney transplant, but not everyone handles the surgery well. One of my aunts had a transplant.
The first problem she had was finding a donor. This took forever. Once a good donor was found, my aunt had a terrible time after the surgery. A transplant is major surgery, and my aunt had complications, including several infections that were very serious.
Then her body tried to reject the new kidney, so my aunt had to take drugs to fight this. The drugs made her sick. She kept the transplanted kidney for eighteen month before it had to be removed.
