Abstract: Acute kidney injury (AKI) is a critical disease in the nephrology department, and has achieved worldwide attention due to its high mortality rate. Pre-renal injuries are the most common factors causing AKI. Negative volume balance in this situation easily results in renal tubular necrosis and accelerates the progress to end-stage renal disease. Maintenance of normal renal perfusion as soon as possible is extremely urgent. On the other hand, volume overload is an independent risk factor for mortality. Therefore, assessment and management of volume capacity in AKI patients must be carried out as early as possible. An effective volume capacity assessment and management strategy is the combination of the initial fluid for resuscitation and the follow-up conservative liquid management. To make renal function back to the baseline values and to reduce patients’mortality, renal replacement therapy (RRT) or conservative control of liquid must be individually planned.
