peritoneal dialysis
A form of renal replacement therapy using the peritoneal membrane as a filter to remove waste products and excess fluid from the blood.
Full Definition
Peritoneal dialysis is the preferred dialysis modality for most children with end-stage renal disease. The procedure involves instilling dialysis solution into the peritoneal cavity through a surgically placed catheter, allowing waste products and excess fluid to cross the peritoneal membrane. In pediatrics, automated peritoneal dialysis performed overnight is commonly used to minimize disruption to school and daily activities. This modality offers better preservation of residual kidney function compared to hemodialysis and provides more flexibility for families managing a child's treatment.
