Hemodialysis is the process of filtering blood through a dialysis machine and removing accumulated toxins and extra water from the body ie When the natural machines of the body- kidneys fails, then artificial machines are used to clean the blood and body. HD may be requires in few cases of acute renal failure where the dialysis is temporary and patient is taken off hemodialysis once his kidney function improves.

Peritoneal Dialysis is an alternate to hemodialysis which is done by the patient himself or his attenders at home. Special catheter is inserted surgically into the abdomen peritoneal cavity. Special fluids called peritoneal dialysate fluids are inserted in and out of the peritoneal space. Peritoneal Dialysis is simpler when compared to Hemodialysis.

Acute Renal failure(ARF) is also known as Acute Kidney injury (AKI). The main function of the kidney is to remove the waste from the body and balance the fluids. When the kidney fails to perform this function, it is known as Acute Kidney injury. When the kidney fails to filter the waste from the body, the chemical action of the blood gets imbalanced as the toxins get accumulated in the body. Acute Renal failure can develop over a few hours or in few days. The patient must be immediately hospitalized to find out the cause of this kidney failure and early treatment can ensure complete recovery.
