Peritoneal dialysis - Definition

Ask a question


Dialysis is a method intended to purify the blood by filtering it through a machine. Peritoneal dialysis uses peritoneum (membrane that envelops the abdominal organs) as a filter. The elimination of toxins and waste that the kidneys no longer manage to evacuate is thus carried out directly between the blood and a special liquid (dialysate), through the peritoneum. Peritoneal dialyses are used in cases of renal pathologies such as a renal deficiency, a glomerulopathy, a nephropathy, and, in certain cases, even diabetes.
