My kidney function is actually improved slightly at 21%. I however have been feeling horrible for the last 3 or 4 weeks with classic ESRD symptoms. My Neph suggested starting PD to get to feeling better and scheduled appointments with a surgeon and a PD Clinic to start training. Is it crazy to start at 21% function? From reading on this site it seems as though most start at much lower kidney function levels. The meeting with the surgeon this Thursday is just a consultation to schedule PD catheter placement.
