- Primary vesicoureteral reflux. The cause of this more common form is a defect that's present before birth (congenital). The defect is in the functional valve between the bladder and a ureter that normally closes to prevent urine from flowing backward. As the child grows, the ureters lengthen and straighten, which may improve valve function and eventually resolve the reflux. This type of vesicoureteral reflux tends to run in families, which indicates that it may be genetic, but the exact cause of the defect is unknown.
- Secondary vesicoureteral reflux. The cause of this form is a blockage or malfunction in the urinary system. The blockage most commonly results from recurrent UTIs, which may cause swelling of a ureter. http://www.mayoclinic.com/health/vesicoureteral-reflux/DS00999/DSECTION=causes
