Kidney Function After Surgery in Children

This international research study is watching children who have major surgery (not heart surgery) to learn how often their kidneys are affected afterward and why some children are at higher risk than others. Researchers will collect information about your child's kidney function before, during, and after surgery using blood and urine tests. The goal is to understand kidney injury after surgery in children—a condition that has received much less research attention than it has in adults, even though early detection and prevention could make a real difference in children's long-term health.

While doctors know a lot about kidney problems in children after heart surgery and in critically ill children, there is very little research on kidney injury following other major surgeries in children. Because even mild kidney injury after surgery can have serious long-term effects, this study aims to fill that gap and help doctors identify and prevent problems before they happen.
