Inventions and other madness

Why not invent an artificial kidney? We have artificial hearts. Why not bypass the kidneys altogether? We have colostomies where the intestines are bad and we have artificial hearts. Why not artificial kidneys? I wonder if someone will invent this technology and how long it would be before they would be designed well enough that our bodies would start to accept them.
