Dialysis is a treatment that cleans the blood when the kidneys fail. On dialysis, a dialysis machine, three sessions of dialysis.

The usual form takes four hours, three times a week, for life or until a transplant, which is why it dominates the life of anybody on it. The machine does chemically what the kidney does biologically: it lets waste cross a membrane and keeps the rest.
