vesicoureteral reflux
Abnormal backward flow of urine from the bladder into the ureters and potentially the kidneys.
Full Definition
Vesicoureteral reflux (VUR) is a common urological condition in children where urine flows backward from the bladder into one or both ureters, and potentially up to the kidneys. This retrograde flow occurs due to incompetence of the ureterovesical junction, which normally acts as a one-way valve. VUR is graded on a scale of I-V based on severity, with higher grades indicating more extensive reflux. The condition predisposes children to urinary tract infections and potential kidney damage (reflux nephropathy). Management ranges from antibiotic prophylaxis and observation to surgical intervention, depending on the grade and associated complications.
