Did you check for both kindneys before you left?
Not a joke. I just heard a story last week about an 11 year girl that had this same procedure done in the same place (Ukraine).
When she came back to America, her parents took her to the local hospital/clinic just to make sure everything was done right.
They found out that she lost a kidney during the procedure
Eta: I meant that I just heard the story last week, but it happened awhile ago I believe.
@OP this wasn't meant to scare. Posting for awareness purposes.
