VUR Glossary of terms

The VUR Terms You Will Hear

If your child is diagnosed with vesicoureteral reflux (VUR) you will hear these frequent terms and acronyms that are frequently used.

  • VUR: Vesicoureteral reflux (ves-ih-koe-yoo-REE-tur-ul re-flux)
    A condition in which urine from the bladder backs up into the ureters. The ureters are the tubes that carry the urine from the kidneys down to the bladder. Sometimes when a child has VUR, urine can flow all the way back up into the kidney.
  • UTIs: Urinary tract infection(s)
    An infection in any part of the urinary system — kidneys, ureters, bladder and urethra. Most infections involve the lower urinary tract — the bladder and the urethra. UTIs are known to be associated with VUR.
  • fUTIs: Febrile urinary tract infection(s)
    Otherwise known as “febrile UTIs”, or a UTI accompanied with a fever. If your child has frequent UTIs with fever, VUR may be involved.
  • VCUG: Voiding cystourethrogram
    A test performed to diagnose VUR. A VCUG takes an x-ray image of the bladder and ureters while the child is urinating (also called voiding) to show anything unusual in the bladder and ureters.
  • RBUS: Renal and bladder ultrasound
    The recommended ultrasound after initial febrile urinary tract infection (fUTI) to evaluate the kidneys and bladder. However, results may be normal despite the presence of VUR.1
  • HA: Hyaluronic Acid
    A naturally-occurring material, and the HA in Deflux has been used for over two decades in more than 40 million procedures worldwide2, often as a dermal filler for wrinkle correction.
