Necrosis of both kidneys will need to be treated with hemodialysis, peritoneal dialysis, or a kidney transplant. The main function of the kidneys in our body is like a filter, which filters toxins and water from the blood and removes them from the body. If the kidney is necrotic, the filtering function of the kidney will be lost and an alternative treatment must be found to maintain the stability of the body’s internal environment. The current treatments for this disease are hemodialysis, peritoneal dialysis and, if available, kidney transplantation. The advantages of hemodialysis and peritoneal dialysis are that they are more popular and less expensive. Compared with the first two types of dialysis, kidney transplantation is more thorough in removing toxins, and it can eliminate the need for additional medications for correcting anemia and calcium-phosphorus metabolism disorders. However, kidney transplants are more expensive and require long-term use of anti-rejection drugs.
