as someone else ready said you don’t lose physical volume when you take a leak, just mass. Since water displacement is a volume thing not a mass thing it would absolutely rise.
I don’t think anything ‘fills’ the physical volume internally when you empty your bladder. I think this doesn’t affect the volume your body takes up in a tub.
if you had a water balloon in a semi-rigid cylinder that doesn’t touch the internal walls of that cylinder, and the balloon is filled with water, and them decided to empty that balloon of water, does that change the volume of the cylinder?

So what fills the volume in place of the pee?
