Why is it important that the fluid in a dialysis machine is isotonic?

So my biology homework is this question ^ and i understand that the kidneys help maintain the bodys natural equilibrium ( i think )  of water/minerals so could someone explain in simple terms so i can re-write it why it has to be isotonic and what would happen if it wasn't?  

Thanks xo

It's not in my book:/

They have an equal osmotic pressure-  so it wont' cause a fluid shift - cells won't burst or shrink (
equal concentration exists inside and outside the cel )
This will also result in substances diffusing from blood into the fluid

The replacement fluid must be of high purity, because it is infused directly into the blood line - so it needs to be clean and not contian anything harmful in order to not damage to body
