(The term stallion for an uncastrated male horse dates from this time; stallion = stalled one.) Stallion is also used to refer to males of other equids, including zebras and donkeys.
Guide. Chronic kidney disease and acute kidney injury (also known as acute renal failure) cause the kidneys to lose their ability to filter and remove waste and extra fluid from the body. Hemodialysis is a process that uses a man-made membrane (dialyzer) to: 1  Remove wastes, such as urea, from the blood. 2  Restore the proper balance of electrolytes in the blood. 3  Eliminate extra fluid from the body.
Hemodialysis may improve your quality of life and increase your life expectancy. But hemodialysis provides only about 10% of normal kidney function. It does not reverse chronic kidney disease or kidney failure. Dialysis has not been shown to reverse or shorten the course of acute kidney injury.
