Peritoneal dialysis in an extremely low-birth-weight infant with acute kidney injury.

Critically ill neonates are at high risk for acute kidney injury (AKI). Renal supportive therapy (RST) can be an important tool for supporting critically ill neonates with AKI, particularly in cases of oliguria and fluid overload. There are few reports of RST for management of oligo-anuric AKI in the extremely low-birth-weight infant weighing <1000 g.
