vesicoureteral reflux
Abnormal retrograde flow of urine from the bladder into the ureters and potentially the kidneys, a common urological condition in children.
Full Definition
Vesicoureteral reflux (VUR) occurs when urine flows backward from the bladder into the ureters due to incompetent ureterovesical junctions. This condition is graded from I to V based on the extent of reflux observed on voiding cystourethrogram. VUR predisposes children to recurrent urinary tract infections and potential renal scarring. Primary VUR results from congenital malformation, while secondary VUR develops due to bladder dysfunction or obstruction. Management ranges from observation with antibiotic prophylaxis to surgical intervention depending on grade and associated complications.
Usage
Usage note: Always specify the grade (I-V) when documenting VUR severity.
