Peritoneal Dialysis as a Renal Replacement Therapy Modality for Patients with Acute Kidney Injury

Since the advent and predominant use of extracorporeal therapies for renal replacement therapies for acute kidney injury, the use of peritoneal dialysis has largely been limited to specific resource-limited settings. This review highlights the current data available for the utilization of peritoneal dialysis for acute kidney injury. Though the current randomized controlled trials have small patient numbers, they have demonstrated peritoneal dialysis to be an appropriate modality for dialysis therapy in acute kidney injury. Current outcomes do not show a difference in mortality, renal recovery rates, or infectious complications when compared to extracorporeal treatments. However, there is a marked heterogeneity in these trials, and more standardized reporting of trial design, techniques, complications, and outcomes is needed.
