Voiding Cystourethrogram (VCUG)

LIke ThisLIke ThisLIke ThisLIke ThisLIke This

A VCUG, or a voiding cystourethrogram, is a minimally invasive test that uses a special x-ray technology called fluoroscopy to visualize your child's urinary tract and bladder.

A VCUG can help:

  • diagnose vesicoureteral reflux - a condition in which urine flows the wrong way, from the bladder back up to the kidneys
  • determine why your child has recurring urinary tract infections
  • discover if antibiotic treatment or anti-reflux surgery was effective
  • check if there are any abnormalities or blockages of the urethra

How Boston Children's Hospital approaches VCUG

VCUGs are performed by the Department of Radiology's Diagnostic Radiology program, which has an experienced team of pediatric radiologists, nurses, technologists and a Child Life specialist dedicated to making your child's visit as safe, pleasant and comfortable as possible.

  • Pediatric radiologists, with extensive experience and training, perform the procedure.
  • Technologists have years of experience in imaging children from infancy to teenagers.
  • Skilled staff employ age-appropriate distraction techniques to help comfort patients prior to and during the procedure.
  • Equipment is designed specifically for pediatric use, which means age-appropriate care for children.
  • Protocols have been adapted to keep radiation exposure as low as reasonably achievable without compromising the image quality.

We perform more than 2,000 VCUGs a year, almost all without sedation. Our Child Life specialist supports your family before and during the exam.
