Hi @klm3

My first transplant was through living donor. I was 17 years old and my donor was my father, he was 40. At that time we were no where close in height. I know the size of the organs matter but im not sure it has anything to do with height. My second donor although he was deceased he was also much taller than I was. He was 18 and i was 37.
I hope this helps a bit.

All the best with your consultation and I hope your surgery goes well if you decide to go ahead with it.
