Kidney dialysis is a process that helps filter impurities out of your blood if your kidneys are not able to do the job on their own.
The kidneys act as filters for your body. Their job is to remove toxins or waste products from your blood. If toxins build up in your blood, you will eventually die.
Other jobs performed by the kidneys. For instance, they keep the right amount of water in the body. They balance vitamins and minerals including sodium potassium and phosphorus. They make sure the acid level in the blood is correct. Your kidneys also help control your blood pressure.
You may need dialysis if you develop end stage kidney failure, which means your kidneys are no longer able to effectively filter your blood. This usually happens if you lose 85-90 percent of your kidney function.
Because your body constantly produces waste products, you must have dialysis on a regular basis to keep your blood clear of toxins. There are two basic types of kidney dialysis: hemodialysis and peritoneal dialysis.
In this procedure, a machine called a hemodialyzer functions as an artificial kidney to remove toxins from your blood. Your doctor will need to insert needles into your blood vessels to allow blood to flow out of your body into the machine where it will be cleaned then sent back into your body through another needle.
Hemodialysis usually takes place at a hospital or dialysis center. Each treatment typically lasts about four hours and must be repeated three times every week.
Your peritoneal cavity is the space inside your abdomen where your stomach, kidneys and other organs are located. In peritoneal dialysis (PD), cleansing fluid called dialysis solution is poured into the peritoneal cavity through a soft tube known as a catheter.
The solution contains chemicals that help pull wastes and extra fluid out of your blood into the abdominal cavity.
The solution needs to stay in your abdomen for a several hours so the chemicals can work. Then all the extra fluid including waste products and extra water are drained out of the abdomen using the same catheter.
