Urodynamics Testing

The urodynamics study is a test used to assess how well your child's bladder and urethral sphincter are doing their jobs of collecting, holding and releasing urine.

  • Normally, muscles and nerves of the urinary system work together to control the release of urine. Nerves carry messages from the bladder to the spinal cord and then to the brain, as well as messages from the brain to the muscles of the bladder and sphincter, telling them either to tighten or release.
  • Urodynamics testing is an excellent way to evaluate how the bladder carries out its two main functions: filling and emptying.

By tracking how the bladder fills and empties, physicians can get clues to why a child may have urinary incontinence or urinary infections. Urodynamics testing can also assess any abnormalities of the upper urinary tract.

A urodynamics study is usually performed when the following conditions are suspected or diagnosed:
