VUR Review

What is VUR?

Vesicoureteral reflux (VUR), sometimes referred to as urinary or bladder reflux, is a serious pediatric urinary condition in which urine refluxes from the bladder through one or both ureters toward the kidneys.

This is due to an abnormality in the region where the ureter meets the bladder. Normally, a valve at the entrance to the bladder prevents backward flow of urine. Infected urine can reflux back into the ureters and, in severe cases, into the kidneys – which may lead to long-term kidney damage.
