Why do urinals flush?

It seems like pee would be just as efficient flowing through pipes all alone? I know some urinals are flush-free, but it just seems like they all could be that way

It stinks, you flush to clean the leftovers. The water-free urinals have systems to reduce the odour. And they still stink.

Additionally, without water, the pipes very quickly get clogged by the build-up of “kidney stones”.
