Everything you need to know about dialysis
Dialysis is a method of treating kidney failure. It does the work of the kidneys to filter waste products in the body and remove excess fluid from the blood. At MSK, dialysis is the only treatment offered for kidney failure.
Hemodialysis treatment and goals
Hemodialysis is the process of removing harmful substances that cannot be removed from the body through the kidneys and accumulate in patients with acute or chronic renal failure, using a filter (dialyzer) that performs the same job as the kidneys. Currently, this method is the most widely used in all countries of the world. When urgent treatment is required for kidney failure, the oldest and most common, the most used treatment today is hemodialysis.
Hemodialysis treatment (Extracorporeal method) is a treatment in which the patient's blood is filtered outside the body using a dialysis machine. During hemodialysis, blood is taken from an appropriate vascular access (fistula-graft-catheter) and passed through a synthetic filter through a dialysis machine. The blood is purified in this dialysis machine before being returned to the body. Hemodialysis is usually done three times a week for at least four hours in a dialysis unit.
To ensure a high quality of life for patients on hemodialysis, it is essential
regularly attend hemodialysis procedures, regularly take prescribed drugs, pay attention to nutrition and salt intake in accordance with the recommendations of a doctor and nutritionist.
You will need to create a vascular access in your body, if one has not already been created. Once the vascular access is open, you will start receiving hemodialysis treatment, usually 2 or 3 times a week for 4 hours. As a vascular access, an atrioventricular fistula (natural vascular access procedure), an artificial vascular access (graft), a temporary or permanent catheter can be used. If a fistula or artificial vascular access has not previously been opened and the patient needs urgent dialysis, the patient will need to have a catheter placed. In an emergency, a temporary catheter is placed in the patient.
Emergency peritoneal dialysis can also be performed in cases where hemodialysis cannot be performed, such as severe low blood pressure and inability to open vascular access. To get you on hemodialysis.
Types of dialysis
Hemodialysis;
peritoneal dialysis;
Hemofiltration;
Hemodiafiltration;
intestinal dialysis;
There are three main and two secondary types of dialysis: hemodialysis (primary), peritoneal dialysis (primary), hemofiltration (primary), hemodiafiltration (secondary), and intestinal dialysis (secondary).

WHAT REMOVES
The uniqueness of the procedure is that it removes harmful substances from the blood that got there from the outside or as a result of metabolic processes. In the case of oncological problems, it is able to reduce intoxication and improve the general condition of the patient.
