In medicine, hemodialysis is a method that is used to achieve the extracorporeal removal of waste products such ascreatinine and urea and free water from the blood when the kidneys are in a state of renal failure. Hemodialysis is one of three renal replacement therapies (the other two being renal transplant and peritoneal dialysis). An alternative method for extracorporeal separation of blood components such as plasma or cells is apheresis.
The suffix of hemodialysis is "-lysis."
When comparing hemodialysis and peritoneal dialysis, it can be said that

hemodialysis takes longer than peritoneal dialysis

Grafts are often the access of choice when a hemodialysis patient has small veins that will not likely develop properly into a fistula.
Hemodialysis treatment may be required to reduce serum potassium levels in hyperkalemic patients with impaired kidney function
Most hemodialysis patients require treatment three times a week, for an average of three to four hours per dialysis "run"
