UF is used to remove water from the body in case of fluid overload. Thus it allows to reduce the pressure within the body, especially on the heart, and to remove water that has cumulated within some organs, such as the lungs, and forms oedema there. At home, this therapy can be used alone or in addition to the others technics. In this latest case, the total volume of fluid injected is less than that removed from the patient, the difference providing the targeted removal of water.

Peritoneal dialysis allows replacing the kidney function when it is not able to do the job adequately. The target is to remove waste products (toxins) from the patient’s body thanks to his own membrane, the peritoneum, which allows transfer of solutes and water to the peritoneal cavity from where it is extracted to a drain bag.

In ICUs, HemoFiltration (HF) is usually indicated in case of Fluid overload, Congestive heart failure, Acute renal failure, Crush syndrome, Lactic acidosis … . But HF may also be successfully used for patients with chronic renal failure. This technique allows removing all the substances that would normally be cleared by the kidneys through the generation of urine such as water, urea, creatinine or salts, as well as medium size substances which result from an injury to body cells and are often nephrotoxic.

HDF is a combination of hemofiltration and hemodialysis which can be preferred to these 2 methods. Reasons for this are, for example, the higher clearance of medium size substances when compared to hemodialysis or less dependence on blood flow when compared to hemofiltration.

As peritoneal dialysis, hemodialysis can be performed at home. It is used in case of chronic kidney failure (CKD). Compared to in-center dialysis, home hemodialysis gives more freedom to the patient who can continue to work and keep an active lifestyle. Home hemodialysis is performed thanks to a machine that the patient manages with a schedule according to his availabilities.
