I am sorry I missed the post last week about your dad being in stage 4, I had a death in the family.
Stage four can be challenging but it can be maintained without dialysis with the right diet. There is not much out in the world for maintaining kidney disease in regards to recipes. However, you can find kidney friendly recipes at davita.com - the entire site is dedicated to kidney disease. I wish you the best! jean
