Finding early warning signs of kidney tube narrowing in babies

This research project is looking for early warning signs in blood and urine that could help doctors better diagnose and predict how a kidney condition called ureteropelvic junction obstruction (UPJO) will develop in young children. Right now, doctors rely mainly on imaging tests like ultrasounds to decide if surgery is needed, but these tests aren't always reliable. By studying blood and urine samples from babies with this condition, researchers hope to find biological markers that give a clearer picture of which children truly need surgery and which ones can be monitored safely.

UPJO—a narrowing where urine leaves the kidney—is the most common birth-related kidney problem in children and can lead to lasting kidney damage if missed. Current imaging methods have significant limitations in reliably identifying which babies need surgery, so many children undergo unnecessary follow-up testing or delayed care. This study exists to fill that gap by discovering biological clues in body fluids that could make diagnosis faster, more accurate, and less risky for children.
