Abstract: 【Abstract】Acute kidney injury (AKI) is a common, acute and critical illness with high mortality. Renal replacement therapy including extracorporeal blood purification and peritoneal dialysis (PD) is an effective method for the treatment of AKI. Peritoneal dialysis is less expensive and convenient, especially suitable for the patients in developing countries. However, it is now less used in western countries and in China. In recent years, many studies have proved that PD is effective and safe for the treatment of AKI. This article discusses its clinical value in the context of advantages, disadvantages and prognosis in AKI patients treated with PD.

Key words: peritoneal dialysis, acute kidney injury, renal replacement therapy
