For patients with end-stage renal disease (ESRD), renal replacement therapy is achieved by dialysis (hemodialysis or peritoneal dialysis) or kidney transplantation. Although true and complete replacement of renal function is not provided by dialysis, this modality removes metabolic wastes and excess body water and replenishes body buffers in order to sustain life.

The apparatus used to conduct hemodialysis consists of the following components:


Dialysis solution (dialysate)

Tubing for transport of blood and dialysis solution
