Will I have to get poked with a needle when I get a peritoneal dialysis?

Not for the dialysis. No needle sticks are needed to do the peritoneal dialysis procedure. But routine blood tests, which require a needle stick each time they are done, are performed at least once a month. These tests monitor the effectiveness of the treatment and monitor the associated problems (like anemia, hormone and electrolyte problems) related to the renal failure that has caused the need for dialysis.
No. Peritoneal dialysis catheter is placed by a surgeon. Once it is placed, just need to connect the tubes for dialysis.
