Never heard of bear urine being used for anything but getting guys (hunters) to spend their money.
Around here, (Va. and WV,) the wildlife "officials" use Anise Extract (purchased at the local grocery store) to get bears to come and get into a live-trap. If the smell reaches a bear's nose he'll be coming right along.
You'll see lots of critters coming to investigate that stuff.
Don't get it on you!
