I have a kidney transplant for 26 yrs. so far but my blood pressure has been a little bit up like 110/90 but it's always been this way. my cholesterol has been going up but my doctor say it's because I've been taking Prednizone all my life. Out of curiosity, I just want to know what is the most that a kidney can last. I have my mom's kidney because I have no sibblings.

Sorry i don't know, but u could try asking the internet!!

I would assume your doctor has your health care well sorted out. But to answer your question, I seem to remember one of the signs was a need to drink lots of water. more than was normal for the person. But I don't think you would be peeing out lots of water. That would spell out something is not ok with the kidneys. But seriously it might be worthwhile to have a specialist check you out, if only just to ease your mind.
