(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.
Introduction to hemodialysis. Hemodialysis is the most common method used to treat advanced and permanent kidney failure. Since the 1960s, when hemodialysis first became a practical treatment for kidney failure, we've learned much about how to make hemodialysis treatments more effective and minimize side effects. In recent years, more compact and simpler dialysis machines have made home dialysis increasingly attractive.
