What are kidneys?
The kidneys are two bean-shaped organs in the renal system which filter waste materials out of the blood and pass them out of the body as urine in human body.
The kidneys perform many important functions, including:
Nephrologist is a specialty of medicine that concerns itself with the kidneys, the study of normal kidney function and kidney disease, and the preservation of kidney health, and the treatment of kidney disease, from diet and medication to renal procedure like dialysis and others.
In condition of kidney damaged or failure, the only purpose of dialysis is to improve renal (Kidney) function. Kidneys’ are no longer able to remove wastes and excess fluid from your bloodstream efficiently. If patient have been diagnosed with chronic kidney disease (CKD), doctor will have these levels carefully monitored. Before dialysis, patients often felt weak and ill. Dialysis brings relief from these symptoms. This is the primary benefit of dialysis.
Dialysis is done by using a special fluid called dialysate. Dialysate, a mixture of pure water and chemicals, is carefully controlled to pull wastes out of patient’s blood without removing substances of patient’s body needs. A semipermeable membrane (one with microscopic holes that allow only certain types of particles to pass through) keeps the blood apart from the dialysate. This membrane lets the wastes and fluid in patient’s blood flow through into the dialysate. Our blood cells and larger molecules, like protein that we need, cannot fit through the holes. There are two main types of kidney dialysis: hemodialysis (HD) and peritoneal dialysis (PD).
