How many forms of dialysis are there?

2: There are 2 types that patients commonly use. "hemodialysis" involves tubes put in the veins, and the blood goes out to a machine that works as an artificial kidney; this takes about 4 hours, 3 times/week. "peritoneal" dialysis involves a catheter (tube) under the skin in the stomach, fluid from bags goes into the abdominal area, then is drained. This process is repeated 4-6 times every day.

2 peritoneal & hemo: The 2 types of dialysis are hemodialysis and peritoneal. Both are effective but have pros and cons. Hemodialysis is generally done at a dialysis center three times a week and requires "access" into the blood stream, a fistula is preferred. Peritoneal dialysis is done at home through a catheter (tube) inserted into the abdominal cavity. You should discuss with your nephrologist what is best for you.
