What can a kidney do that a hemodialysis machine can't do?

In brief: Many things

It has a much finer filtering mechanism to selectively remove waste products.
The kidney also has endocrine function meaning it can respond to other hormones in the body such as parathyroid hormone to keep the bones healthy and aldosterone or vasopressin that aid in salt and water control. The kidney also can produce hormones that stimulate the bone marrow and produce vitamin d.

In brief: Good question

A machine cannot replace all that a kidney does.
The kidney makes some hormones and activated vitamins.It also works round the clock and eliminates substances more efficiently that the machine so if posible a kidney transplant would be the best option.

In brief: Regulate by itself

A living kidney filters your blood, letting out excess fluid and poisonous waste products, adjusts your acid/base (ph) balance, adjusts your blood pressure, and makes hormones to stimulate red blood cell production + control calcium metabolism. Though many of these functions can be replaced with dialysis and hormones, the management is quite tricky.
A healthy kidney does it all well independently!
