All I know is when I do dialysis I dont urinate very much ...but when I dont do D that day I go alot.... really alot... and if I skip a day I still go alot..... Seems like my kidneys work better when I dont do D.....
Urinating does not equal cleaning toxins when you have ESRD. You can pee constantly and still have toxin build up. If you are still urinating, though, it makes sense that you would urinate more on the off days. The machine has pulled fluid from your bloodstream while you were hooked up. On the off days, there's more fluid in the bloodstream for your kidneys to expel. They don't necessarily work better - they just have more to work with.
I just have to wonder here, and of course I to am trying to figure all this out (and probably never will lol), but I always seem to think along the lines that having 8 or even 12% kidney function is pretty the same as having 0. I guess that little bit left is enough to sustain life function for a while but with the way you get sick with symptoms to me again again takes me back to it's life having 0. How does having at least some very small residual benefit you? Example: keeps you urinating etc... so confusing!
