Urine is actually extremely well filtered.
It's been through one of the best filtration systems in the world: the human body. I think it's meant to be antiseptic. So, the urine thing is pretty lame, really.

I used to know some people who drank piss. One guy even offered a half-wine, half-urine glass to his friend's mother, who drank it. I don't see those guys too often anymore.

It's a shame we don't have the plague anymore, now that would be a strange fetish.

Edit: I seem to have accidentally pressed 'enter'. Which led to the repeat, now deleted.

It is indeed clean, and in a healthy body it should be as good as sterile upon exit
That's not to say I'd want to lie in a urinal and be doused in the stuff...

Urine leaving the body may be sterile (if you don't have an infected bladder),
urine that's been lying in a dirty urinal blocked up with gum and fag butts for a few hours is a fucking health hazard.
