According to the National Institute of Diabetes and Digestive and Kidney Diseases, "The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of your spine." The kidneys are why our body can flush acids and extra wastes out of the body and control the level of salts and minerals in the blood. 

Because of the vital functions of the kidneys, life expectancy is contingent on the body's renal health. One abnormality that can pose a risk to your kidney's health is kidney disease. This disease is when the kidneys cannot function as they're supposed to. When this happens, kidney disease can worsen until the stage of the disease reaches end-stage kidney failure. At this point of the disease, a patient needs outside treatment since the kidneys are failing. Often, medical professionals recommend patients proceed with dialysis treatment.

What is Dialysis?

Dialysis is performed on patients with end-stage kidney disease. The purpose of this procedure is to remove excess fluids or wastes from your body. Among the types of dialysis there are hemodialysis and peritoneal dialysis and dialysis access care. 

According to the National Health Service in England, "Haemodialysis involves diverting blood into an external machine, where it's filtered before being returned to the body." During this process, the patient lays down and is injected with needles connected to a dialysis machine. This machine filters the patient's blood through a cleansing fluid called dialysate. Once extra fluids are filtered from the blood, the blood is returned to the patient through the injected needles.

Peritoneal dialysis filters the excess fluids from the blood by pumping dialysis fluid directly into the abdomen. To do so, a doctor makes an incision allowing a tube called a catheter to be placed inside your belly. Thirdly, as stated on our website, "the vascular creation and care of your vascular access for dialysis." A surgeon operates on the venous system during dialysis for blood to filter.

Life Expectancy

Some dialysis patients live well past ten years, but some could live as short as five years. Research finds a varying risk of death between patients being treated with peritoneal dialysis and those treated with hemodialysis. One study states, "The average life expectancy of a person on hemodialysis is less than three years and hasn't changed in 20 years." Another study found after studying a group of hemodialysis patients that most of these patients passed away within five years.

Regarding peritoneal dialysis, research suggests that the risk of death is lower for patients who proceed with peritoneal dialysis over hemodialysis. It is also worth noting that there is ongoing research being conducted on mortality rates of dialysis. These rates also depend on a variety of contingent factors, including age.
