@vickipm I just celebrated my 61st anniversary of having a kidney removed for cancer! I am truly blessed. I had 2 babies, multiple surgeries and have been told that my one kidney is larger. My son, age 54, just had surgery for the same thing in January. His kidney function tests have improved over the past year and he is now having normal lab values. We both watch how many CT with contrasts we get. Normally, kidneys work at around 50% each. So, it takes awhile to get the other one working more efficiently. Yes, hydration is important and we never forget we have one in watching out for UTIs and such. Otherwise, it all works out! Good luck!
