What if urine was reprocessed by large intestines? - Lemmy.world

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?

Am doctor, you are essentially asking about a fistula (abnormal communication) that would allow urine and bowel to mix. This would allow for communication of gut bacteria to then invade the urinary system which would then easily cause a kidney infection which would then seed the blood resulting in bacteremia. Bacteremia is bad, like you die from infection unless you are on IV antibiotics and get the source under control bad. As an example, colovesicular fistula is a communication between the colon and bladder which often results in bad infections and needs to be surgically repaired. Hope this helps.

Ok but why cant I have a secondary urethra grafted in that runs in my leg down to a nice discreet exit on my ankle so I can take a sneaky wee when Im out and about.

Then you’d be right back where you started for my purposes, still losing moisture unnecessarily.

You could just tape a garden hose to your dick and run it down a pant leg. Man, I should patent this idea....

That's called a condom catheter. Don't hook it up to suction.

I can’t. Hose widths are too big.

Look up an endurance racing catheter.
