Peritoneal dialysis uses the peritoneum (the thin lining of the abdominal cavity) as the filter for separating waste products from larger substances. The dialysis is performed with a special tube that a veterinarian uses to fill the cat's abdominal cavity with dialysis fluid. Waste products in the body suffuse into the fluid. The doctor then removes the fluid from the abdominal cavity and discards it, repeating the procedure until the level of waste products is adequately reduced.
Peritoneal dialysis is easy to perform in cats and is not painful for the patient. The need for constant monitoring and professional application usually limits the use of peritoneal dialysis to the treatment of reversible acute renal failures where the dialysis performs the waste removal function of the kidneys while the kidneys themselves are recovering.
