Abstract: 【Abstract】Hyperphosphatemia is a common complication of chronic kidney diseases and is also important predictors of cardiovascular disease and all- cause mortality in peritoneal dialysis (PD) patients. Hyperphosphatemia is common in PD patients and seriously affects their quality of life and prognosis. Clinically, the complicated management of serum phosphorus involves diet, phosphorus binding agents, residual kidney function and PD. However, the factors affecting phosphorus clearance in PD patients are still controversial. This article reviews the research progress about the influencing factors on phosphorus clearance in PD patients, hoping to make a better comprehension of this issue and to find key points for intervention.
