What if urine was reprocessed by large intestines?
I have wondered many times how a human would fare if the kidneys dumped urine into the start of the large intestines somewhere about the appendix instead of into a bladder to be sprayed out. I'm assuming water would be reabsorbed and slower to process out, primarily through sweat and evaporation from the lungs, and maybe diarrhea, though it may be that other waste products, such as salts or ureas may be absorbed into the large intestines instead of being ejected, though I have no idea if it would, or if it would be ejected as intended. Do we have any biologists here that could give insight on if combining both waste paths into one would be advisable?

The kidneys already recover water and salt. Google the loop of Henley.
What we pee is what our body considers in excess. We intake a lot of our water from food, so we need a way to expel that. Peeing is much nicer than bloating and constant Diarra.
True, though as is, we still need to take in water due to a shortfall in what we do take in. That said, I'm also wondering if my proposal would also result in other waste products being recirculated and building up in the system, causing their own complications.
You are asking for kidney stones. There's a chemical reason you want plenty of water to dilute your waste, that is avoid precipitation

One waste product building up would be water, in that case
