I realize I could research this myself -- at least enough to ask a more informed version of this question -- but I've been procrastinating that since when I first read your comment, so:
Could you talk about your decision to donate the kidney and what your judgments of the tradeoffs were? (I assume, since you didn't mention otherwise, that this donation is not to a friend or family member.)
If you want people to ask you stuff reply to this post with a comment to that effect.
More accurately, ask any participating LessWronger anything that is in the category of questions they indicate they would answer.
If you want to talk about this post you can reply to my comment below that says "Discussion of this post goes here.", or not.
