A guy I work with was out a few days last week with kidney stones. This prompted us to to look on Wikipedia (they call it Peteypedia at work because I always use it to settle bets) .
So theres a really ugly picture of a kidney stone on the page but the big thing that got me was they say that you should produce 2 to 2.5 liters of urination a day as an indication of a healthy piss system.
So thats like 70+ fluid ounces or more than a rectangular carton of orange juice a day.
I thought about trying to collect and measure my 'throughput' this weekend but then I realized how fucking stupid that was.
Instead, I'm just going to drink a lot of water and hope for no kidney stones. FOR THE NEXT 30 YEARS
Urinary Health:

nah... that's too much... "acceptable" urine output is 0.5 ml/kg/hr- the "avg person" is 70kg so that's 35ml/hr. That's 840/day. Give or take.
Just call me jenksipedia.
I heard somewhere that you are supposed to drink around 6 or 8 glasses of water a day. I'm not sure how much pee that would make. But what I can say is that it doesn't only come from stuff you drink. I don't know how much you get from things that have water or juice in them like fruits and vegies but should get some from things you eat.
im gon recognize!
