I already had an orchiectomy so I might not be able to do it but I am curious.
If you are not a Croatian resident what makes you think you are entitled to their healthcare benefits?
Unless you pay taxes in Croatia you can forget about other Croatian tax payers funding your surgeries.
Better check that you'd qualify. You might not, seeing as you live in the US.
Probably.
Is this really something you want to be done by the lowest bidder or by a hospital with an international reputation for doing amazing work and figure the costs out later?
