Just got my labs, Potassium 5.7, BUN 90, Creatinine 10.3.GFR 5. Last week I had surgery to put a PD catheter in place for use if needed. Post surgery I was constipated from the pain meds and had difficulty urinating, due to the Foley catheter. Other than getting tired easy from physical exertion I feel good. My doctor wants me to start PD dialysis this week, I think it is moving too fast. My questions is could the labs be skewed due to constipation and difficulty urinating? Both conditions have passed I think I should have my labs redone as I still feel well enough and staying functional at work. I don't want to be stupid about not starting dialysis but don't want to until symptoms warrant taking that final step.
