How to treat renal failure?

Acute renal failure is usually reversible if treated promptly and appropriately. Dialysis may be required temporarily. This is a method for removing waste such as urea from the blood when the kidneys are incapable of this.The kidneys will recover with resumption of adequate renal perfusion with fluid resuscitation (i.e.the injection of fluid into a blood vessel to normalize blood pressure and urine output). The underlying cause should also be investigated and treated. However some patients might never regain full renal function and require dialysis.
