sorry not from me. may be your friend should seek alternative ways while doing his dialysis.
i will help say a prayer to God ask only.
why?
1.he going take another's organ. personally is not something i condone.
we all want live forever, but i not want support taking others organs.
you may not be aware what evils of organs harvesting.
i understand the desperation.
i also need heart, but i will not take anothers.
2.full recovery is unlikely only extending time.
3.If the medical facilities want help him , there's lots they can do, other than extorting him down to his underpants.
difficult choices, God put him in a difficult position. But try think of the number of peeps in his situation. You will be shocked.I know a few, seems they managing struggling thru fighting for life too.
i not a cruel person, but there is limit to things i will do help others.
Sorry.
regards
