Urgent-Start Peritoneal Dialysis: Current State and Future Directions

Urgent-start peritoneal dialysis (USPD) is defined as peritoneal dialysis initiated within 14 days of catheter insertion. In this review, the authors describe the most recent data on USPD, including outcomes, complications, barriers to implementation, and areas for future research. Outcomes appear similar between catheter insertion techniques, so patient factors and institutional workflow should guide practice. Mechanical complications may occur at a higher rate in USPD, but it does not impact technique survival or mortality. Infectious complications appear unchanged in USPD, and there may be fewer complications compared to urgent-start hemodialysis. Barriers to implementation are multifactorial, including physician and staff unfamiliarity and lack of institutional support. A significant limitation within the field includes lack of uniform terminology and definitions.
