The kidneys are responsible for filtering waste products from the blood. Dialysis is a procedure that is a substitute for many of the normal duties of the kidneys. The kidneys are two organs located on either side of the back of the abdominal cavity. Dialysis can allow individuals to live productive and useful lives, even though their kidneys no longer work adequately.
A properly functioning kidney helps prevent salt, extra water, and waste from accumulating in the body. It also helps control blood pressure and regulates important chemicals in the blood, such as sodium (salt) and potassium.
When the kidneys don’t perform these functions due to disease or injury, dialysis can help purify the blood and remove waste.
Renal Dialysis is a form of treatment that replicates many of the kidney’s functions. Renal Dialysis filters the blood to rid body of harmful waste, extra salt, and water. There are two types of dialysis – haemodialysis and peritoneal dialysis. If patient has acute kidney failure he/she may need dialysis for only a few days or weeks while kidneys recover. If kidneys are too badly damaged then patient will need long-term dialysis or a kidney transplant to live.
Hemodialysis treatments usually last three to five hours; but its variable for each patient.
Dialysis is not a cure for kidney disease. It replaces the work of the kidneys which is unable to function. Dialysis treatments are needed lifelong until the kidney transplant is planned.
