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

Urinals with water are there to make sure everything “moves downhill” and keep the uric-acid diluted. It also keeps the urinal washed clean.

With waterless urinals, the water use is significantly reduced. But to make sure that uric-acid crystals do not build up in the pipes, the wash sinks have to be installed upstream of the urinals to keep the acid diluted.
