Peritoneal dialysis (PD) is a treatment for kidney failure that uses the peritoneum, a thin sac that surrounds the intestines, as a natural filter. During PD, a special fluid called dialysate is introduced into the abdomen through a small tube called a catheter. Wastes and extra fluid are removed from the blood and passed into the dialysate https://hallbook.com.br/blogs/441746/Peritoneal-Dialysis-An-Alternative-Treatment-for-Kidney-Failure
