Since I recently had a Partial Nephrectomy on my one and only kidney, I find that I wake up with a very dry mouth. I have been pushing fluids, drinking at least 8 full glasses of water per day, plus drinking juice and coffee at least once a day. Now I am worried that I should not be doing that. I have not been checking my urine output, but it appears okay. So does anyone know what I should be doing? After the surgery I am pretty much out here on my own until I can get in to see a Nephrologist. I can't get answers from the surgeon or my Urologist or even my PCP. It feels like they have just finished what they planned and now I am in the dark. Out on my own. Help...
