Correlation does not equal causality. Many trappers have a dog with them when they set their trap lines. The dogs will show where fox and coyotes have marked. A good place to set a trap. They also will set traps where the dog itself marks. To most animals, urine is a communicator--within species--and an attractant or curiosity with other species. You can set traps and mark the sets with a strong dose of coyote urine (the top of the food chain predator in most areas without wolves or significant numbers of lions) and will catch coyotes, foxes, bobcats, stray dogs and cats, skunks, rabbits, raccoons, badgers, weasels, mink...
Some animals will certainly shy from human scent, but your places are already saturated with human scent. The biggest long term effect of putting human urine out over time will likely be an increase in salt content in the soil in those areas. Increased salt will attract more rodents. More rodents attract more predators.
I'll be the odd one out here and assert that these strategies will be temporarily effective, if at all. Animals quickly acclimatize to new things once they learn there is no real danger. Dried blood, fresh or dried urine, ultrasonic devices: All provide temporary--if any--results. Juicy chickens are a a great motivation for quick learning in predators.
