Abstract: 【Abstract】Phase angle (PA) is a quantitative marker derived from bioelectrical impedance analysis. PA has the advantages of being objective, convenient and quantifiable, and is now widely used in clinical practice for the management of malnutrition, muscle loss and volume overloading in maintenance hemodialysis patients. This article reviews the current research progresses in PA in maintenance hemodialysis with the aim of guiding clinical management of maintenance hemodialysis patients.

Key words: Phase angle, Maintenance hemodialysis, Malnutrition, Sarcopenia, Volume management
