Do I have to go on dialysis if my kidneys fail?

Probably. Whether you have to start dialysis depends on how bad your kidneys are failing as well as other medical problems you have. The worst kidney failure is called stagev chronic kidney disease and indicates less than 15% kidney function. Most times a patient will be started on dialysis if the function falls below 10%, sometimes at a higher or lower level, depending on symptoms. Ask your nephrologist.
RRT options. There are five renal replacement therapy options I always discuss with patients who are about to start dialysis. 1. Blood dialysis a) in center (hd) b) home (hhd) 2. Peritoneal (ccpd or capd) (also done at home) 3. Renal transplantation 4. Comfort care. Not everyone decides to use this technology.
