Peritoneal dialysis patients worldwide account for about 11% of the global dialysis population. The global annual growth rate of peritoneal dialysis is estimated to be 8%, which is listed as the preferred method of renal replacement therapy in most countries. Although peritoneal dialysis has been widely used, due to complications such as peritoneal dialysis related infection, peritoneal ultrafiltration failure and EPS, the failure rate of peritoneal dialysis technology is high, and the 3-year technical survival rate is only 64%. Therefore, this study intends to explore clinical strategies for maintaining the long-term peritoneal dialysis by analyzing the clinical characteristics of patients , as well as the differences of risk factors affecting the survival rate of peritoneal dialysis technology at different time stages of peritoneal dialysis treatment.
