There are two types of dialysis – hemodialysis and peritoneal dialysis.

HD uses an out-of-body filter called a dialyzer. With the help of the hemodialysis machine, the blood from the body is filtered through an artificial membrane – “dialyzer”, or “artificial kidney” to clear toxins that the kidneys can no longer remove. Peritoneal dialysis is a way to remove waste products from the blood in a different way from the more common blood filtration procedure called hemodialysis.

A peritoneal catheter is required before initiating PD. PD uses the lining of the abdominal cavity, called the peritoneal membrane, which serves as a natural filter to remove fluids and harmful substances from the blood. This is achieved by periodically infusing a special solution into the abdominal cavity. The lining of the abdomen (peritoneum) acts as a filter to remove waste products from the blood. Your doctor can tell you which type of dialysis may be the best option for you.

Factors to consider are:

– Your kidney function – Overall health

– Your personal preferences

– Your way of life

Peritoneal dialysis may be a better option if:

– You want to minimize the interruption of your daily activities

– You want to work or travel easier

– You have some residual kidney function

Peritoneal dialysis may not work if you have:

– Adhesions and mechanical defects of the abdominal wall also complicate the procedure.

– Inflammatory bowel disease or frequent attacks of diverticulitis

– Impossibility to observe strict hygienic measures

Advantages of peritoneal dialysis

– No vascular access with fistula or catheter is required;

– Patient mobility

– The therapy is carried out at home

– Lower risk of transmitting dangerous viral infections.

Disadvantages of peritoneal dialysis:

– Risk of infections

– Risk of obesity

– Impaired fat metabolism

– Cleansing from nitrogenous bodies (urea and creatinine) is not so good
