 Hi, I am Dr. Rohan Agastin, consultant nephrologist at Manipal Hospital, Bangalore. I will be talking to you today regarding dialysis. Many of you all would have heard about this term dialysis. Dialysis in brief means it's a form of renal replacement therapy. Now, what I mean by that is when people have kidney failure, either temporary, which is called commonly as acute kidney injury, or chronic ESRD, that is end stage renal disease, these patients are put on dialysis, which is a form of renal replacement therapy, wherein the blood is purified through a filter artificially, thereby renewing all the waste products, water, and all the metabolic toxins that accumulate through the kidney failure. Now, broadly speaking, many a times people ask, is this dialysis going to be temporary or permanent? Well, that actually depends upon the nature of the kidney failure. So, if the kidney failure is temporary, then the dialysis also would be temporary, and if the kidney failure is permanent, then people are put on permanent maintenance dialysis. Now, dialysis is a broadly of two kinds, one which is commonly encountered and that is called hemo dialysis. The term itself means it's hemo, that is blood, and dialysis is a filtrate. Thank you.
