vesicoureteric reflux

Backward passage of urine from the bladder up into the URETERS during voiding. This occurs, mainly in children, because of failure of the valve-like effect of the oblique entry of the ureters through the bladder wall. Organisms from the bladder are able to gain access to the kidneys and set up an acute PYELONEPHRITIS.
