The department provides all forms of dialysis including Haemodialysis and Peritoneal Dialysis. Dialysis is a treatment that does some of the things that are done by healthy kidneys. It is needed when the kidneys have been damaged and are not able to carry out their normal functions. With the result there is retention of waste products in the body along with salt, water and other chemicals. This may happen during temporary failure of the kidney (a renal function) and when there is permanent damage (chronic renal failure).
