<P> Vesicoureteral reflux ( VUR ) , also known as vesicoureteric reflux , is a condition in which urine flows retrograde , or backward , from the bladder into the ureters / kidneys . Urine normally travels in one direction ( forward , or anterograde ) from the kidneys to the bladder via the ureters , with a 1 - way valve at the vesicoureteral ( ureteral - bladder ) junction preventing backflow . The valve is formed by oblique tunneling of the distal ureter through the wall of the bladder , creating a short length of ureter ( 1 -- 2 cm ) that can be compressed as the bladder fills . Reflux occurs if the ureter enters the bladder without sufficient tunneling , i.e. , too `` end - on '' . </P>
