Oh Becky~ I am shaking right now, but w/joy that your friend's son will get a new lease on life. My DS had a kidney transplant in 1994. We went through the living related donor program and Yes, he has my left kidney. I would give another one, if I had a spare, as seeing new LIFE in my DS was the most amazing thing in the world.
I am so very anxious to hear how all is going. Just remember, they have amazing anti rejection meds now and can stop a rejection most of the time, if in fact it would happen, as long as the recipient keeps up w/labs, appts etc.
I am so happy that your friend's DH is giving life to his son not once, but twice. Keep us posted and I am praying everything is going well.
PS: They can now remove a kidney w/smaller incisions~ when I had mine done, it was through a larger incision. Prayers are going out to the family.
