I was born with a "bad kidney" on the left side, which caused me many problems until the doctors discovered and removed it when I was four years old. I have been relatively healthy ever since, and the right kidney is doing just fine. I do take a some minor precautions, and I was told by a doctor that, some day, if I were to become pregnant, that I should be considered a "high risk pregnancy". No real reason, he said, just to keep an extra eye on things since everything is in there together.
I'm just wondering: with no kidney on the left side and a kidney (so I'm told) 2X the normal size on the right-- has anyone ever heard of issues with carrying a baby when you don't have normal kidneys?
