Kidneys filter our blood by removing waste and excess fluid from our body. This waste is sent to the urinary bladder to be eliminated while urination. Dialysis performs the function of kidneys if they have failed. End stage kidney failure occurs when the kidneys are performing only 10 to 15% of the normal functionality. Dialysis is a treatment that filters and purifies the blood using a machine. This helps to keep your fluid and electrolytes in balance when the kidneys can not do their job. Narayan Swaroop Hospital has 3 dialysis units. Dialysis is performed through AV fistulas or temporary access for dialysis.
