The first dialysis unit was established in 1997 at Priti Hospital, Prayagraj, Uttar Pradesh. The unit was led by Dr. Priti Gupta, who is considered to be the Mother of dialysis in Prayagraj.

Dialysis is a medical treatment that is used to remove excess waste and fluid from the body when the kidneys are no longer able to function properly. It is typically used in people with kidney failure, a condition in which the kidneys are unable to filter waste and excess fluid from the blood. There are two main types of dialysis: hemodialysis and peritoneal dialysis. Hemodialysis involves removing blood from the body, filtering it through a machine, and returning it to the body, while peritoneal dialysis involves using the lining of the abdomen (the peritoneum) to filter the blood.

First dialysis unit was a primitive machine that used a drum filled with cellulose fibers to filter the blood. The machine was used to treat patients with acute kidney failure, but it was not practical for long-term use. Today, dialysis is a widely accepted and effective treatment for kidney failure, and there are many different types of dialysis machines and techniques available.
