I did the postal 10k last year and it wasn't an issue even though I was in the water for just over 3 hours. And I was drinking 8 oz water every 2k.
I can't imagine swimming 10k continuous in a 25y/m pool (1650/1500 seems like enough), although im tempted to try a 100x100. Unless i was cold, nervous or overhydarted i think id make 3hrs swimming without having to go - you are sweating and using up water for metabolism, and unless you are just cruising you are probably using more water than you are taking in and probably slowing down your kidneys.
I don't go in the pool, but from what ive read and heard, i think many AGers and college swimmers aren't getting out to go during practices.
In open water i think everybody just goes in the water, ive had to pee in my wet suit many times while surfing and more recently swimmming - it warms you up :) or you can let a little water in to move it thru - hose or shower after you get out, so dogs do't think you're a walking hydrant.
A friend growing up with a back yard pool (these weren't very common in the 50s) had a sign that read: "I won't swim in your toilet, if you don't pee in my pool."
