vesicoureteral reflux
Abnormal retrograde flow of urine from bladder to ureter, predisposing to urinary tract infections in children.
Full Definition
A urological condition where urine flows backward from the bladder into the ureters and potentially to the kidneys due to incompetent ureterovesical junction. Vesicoureteral reflux is classified by severity (grades I-V) based on radiographic findings and represents a major risk factor for recurrent urinary tract infections and renal scarring in children. The condition can be primary (due to developmental anomaly) or secondary (due to bladder dysfunction). Management approaches range from observation with antibiotic prophylaxis to surgical intervention depending on grade, age, and clinical factors.
Usage
Usage note: VUR is acceptable abbreviation in urological contexts; use American spelling 'vesicoureteral' not British 'vesicoureteric'.
