I Have Kidney Failure and Would Like to Do Fat Grafting to my Butt? Is It Safe?

Hi, I have kidney failure, and I'm looking to do lipo with fat grafting to the butt. I am not on dialysis and I still make urine fine. I am 34, no diabetes, or high blood pressure. I already have a date set. I just know they say a 2nd opinion is a MUST...so I'm asking to make sure it's safe. I don't want to further harm me kidneys, which I doubt. Will do..but just want to make sure!?, thanks for reading this all help will be very appreciated!!!! Thanks
