The fluid that is removed each hour is not called urine; it is known as ultrafiltrate. Typically, some of the ultrafiltrate is replaced through the continuous renal replacement therapy circuit by a sterile replacement fluid. Diffusion is the movement of solutes along a concentration gradient from a high concentration to a low concentration across a semipermeable membrane. Convection occurs when a pressure gradient is set up so that the water is pushed or pumped across the dialysis filter and carries the solutes from the bloodstream with it.
