I’ve never seen this aspect dealt with in any of the articles I’ve read about the urinary system

    Pure guesswork because I’m way too lazy to dig:

    There’s the actual pressure of the liquid, then the muscles that hold the pee in have to strain more to resist that pressure.

      You know what? I liked your answer. You didn’t claim it was truth, and it started a discussion. I think it sounds like a reasonable enough theory, it’s probably weirder than that, because that’s usually how things be, but I like how you think!

        So is OP.

        And that “nonsense” makes perfect sense. Exactly like your sphincter keeps you from shitting your pants, there are muscles that hold your urine in.

        What do you think “holding it” means? It means you’re tightening the muscle to prevent flow. The more you have to strain to do so, the more fatigued that muscle gets.
