I understand the advantage of adrenaline when I'm nervous/scared, but what is the point of the overwhelming urge to use the toilet?

You should really look at this from an evolutionary point of view. You've got a point that for humans, who actually go to the toilet, emptying the bowels is quite the hassle and not compatible with quickly running away from danger or fighting your way out. When we look at other species however, it makes a lot more sense.

Digestion demands, paradoxally, quite a bit of energy. Furthermore, all the undigested food in the gut becomes nothing more than dead weight when you're running for your life. For example, if a deer is suddenly set upon by a mountain lion, it will immediately expel all food from it's gut, effectively making itself lighter, more nimble and giving it the opportunity to provide energy to the processes that are most important: running like hell.
