Chronic kidney disease is a significant problem of public health worldwide, and up to 60% of patients start dialysis in an unplanned manner without a definitive dialysis access. In recent years, peritoneal dialysis (PD) has emerged as a novel method of urgent-start dialysis, and the relative researches in the world have showed that urgent-start PD can be an efficient, safe, and cost-effective alternative with comparable outcomes to the planned PD and urgent-start hemodialysis (HD). More importantly, the performance of urgent-start PD has significantly reduced the incidence rates of catheter-related bloodstream infections and dialysis-related mechanical complications compared with urgent-start HD using central venous catheter.
