<unk>  is a procedure to remove waste and excess fluid e.g. urea and potassium from blood when kidneys are no longer capable of doing so, such as in cases of renal failure.<unk>  is a type of renal dialysis and therefore also referred to as renal replacement therapy. It follows the process of diffusion, wherein<unk>  membrane surrounding the abdominal viscera serves a semipermeable membrane and can, in the presence of specifically formulated dialysis fluid, help dialysis. Another process involves osmosis wherein excessive fluid can be removed by altering the concentration of glucose in the dialysis fluid. The fluid used for dialysis is instilled via a catheter. The most common dialysis catheter is Tenckhoff Catheter. It is placed in the patient's peritoneum and runs to the skin surface near the umbilicus. These catheters may also be tunneled subcutaneously and exit various locations such as near the rib margin or close to sternum (presternal catheter) or even higher  near the clavicle. The procedure involves a small surgery and choice of exit site is influenced by multiple factors viz patient's or surgeon's preference, anatomical variations, and/or ability to maintain good hygiene.<unk>  can be done anywhere; at home or at workplace and all it requires is a clean area, a way to elevate the fluid bag, and means to warm the fluid. As one may imagine, there is, however, a predilection for infection e.g. peritonitis. Hence the importance of taking hygienic precautions cannot be over emphasized.
