Polycystic Kidney Disease (PKD) Support Group
Polycystic kidney disease (PKD) is a progressive, genetic disorder of the kidneys. It occurs in humans and other organisms. PKD is characterised by the presence of multiple cysts (polycystic) in both kidneys. The disease can also damage the liver, pancreas and rarely the heart and brain.
if you are planning a kidney transplant I would think any plastic surgery such as tummy tuck should wait until after that is done.
As for a tummy tuck, I did not have one and I was sure I would have a lot of loose skin. My sister has the "elephant skin" from her pregnancies and so does did my mom but I am lucky enough that despite the huge size of my abdomen, it shrunk right back to normal with no loose skin. I'll hope for the same for you. (although I have a huge scare running down my abdomen, so it doesn't matter much--I'm still not bikini material!)
