The treatment of renal failure is to find the cause of the disease and treat the cause. If it is acute renal failure, common causes are dehydration, urinary tract obstruction and the use of drugs that are toxic to the kidneys. Patients need to be treated for the cause, for example, patients with dehydration need to be rehydrated and patients with urinary tract obstruction may need surgery to remove stones, tumors and other problems. If it is due to exposure to toxic drugs, patients need to stop these drugs immediately and may also need to be treated with hormones and other medications. If the chronic kidney failure is caused by diabetes, blood sugar control is needed. In the case of chronic nephritis with a urine protein quantification of more than 1 gram, patients may need to be treated with drugs such as glucocorticoids, while multiple myeloma may require chemotherapy.
