Kidney dialysis is a treatment which usually involves using a machine to take over kidney function to filter toxins, waste, and excess fluid from the body. The treatment is required by patients whose kidneys are not functioning properly.
The kidneys serve the function of filtering the blood to remove excess fluid and waste products by turning them into urine. Dialysis is needed when the kidneys fail to function properly, which in some cases, may be a temporary problem. However, kidney dialysis is most commonly required by patients who have kidney failure, which will likely require dialysis until the patient receives a kidney transplant.
There are 2 different types of kidney dialysis, hemodialysis and peritoneal dialysis.
Hemodialysis is the most common type of kidney dialysis and involves connecting a tube to a vein in the arm, which is connected to a machine that is used to filter the blood. Hemodialysis is required 3 times per week and each treatment session takes up to 4 hours.
Peritoneal dialysis is a less commonly used type of kidney dialysis that involves filling the abdominal lining (the peritoneum) with fluid that enables the filtering of the blood. Peritoneal dialysis is required daily and can be performed by patients at home. It will need to be performed 4 times a day.
Patients who require kidney dialysis will need to continue their dialysis once they go abroad on holiday or if they travel overseas.
