Pediatric acute kidney injury refers to the sudden loss of kidney function due to an underlying illness.

What is a Pediatric Acute Kidney Injury?

Acute (sudden) kidney injury, formerly called acute renal failure, occurs when a kidney is damaged suddenly due to an illness or condition – not because of a blow or injury to a kidney as the name might suggest. It’s a sudden onset of kidney failure that can happen within a few hours or days.
