Constant Urination

[MotRemlap]

Hi All! this question might seem Banal but has been weighing on my mind for a while. Basically is it possible for a human being to produce a constant stream of urine indefinitely or, what is the longest time someone can piss for. If you are drinking in at the same rate you are urinating ( you could use one of those camelbak devices) with a ffew pints already in the bladder obviously, wouldd this be possible, or does the act of weeing close the "input" to the bladder from the stomach or wherever so it is impossible, im not looking for how difficult it would be to do practically, just is it theoretically possible, Cheers in Advance.

if your contractors are not strong enough, you're releasing a little of urine basically all the time

Humans produce urine all the time, but in healthy persons a certain amount of it needs to accumulate into the bladder for urinating to be possible. So one can only urinate once in a while because the pressure needs to build up a bit. Probably with some practise and lots of drinking one could urinate almost constantly, but that would risk a loss of electorlytes that would probably end the project at some point.

However, e.g. people with a drain or catheter put into their bladder basically urinate all the time.

Why loss of electrolytes? I guess he would urinate the final urine, not the primary one...

Urine always contains some electrolytes, if you simply drink water or other electrolyte-deficient drink, you end up losing electrolytes. You actually lose a fair bit of other stuff as well, eventually.

Probably with a right kind of drink that would not be a problem, but you still cannot pee non-stop due to the other difficulties I mentioned :)

As I said, even in the case of constant urination, you would lose the final urine, so nothing more, than usuall. You would be just loosing it all the time not once per day...

you could do it if urine flow rate ~ glomerular filtration rate
