We Put Your Child's Needs First
Our experienced advanced practice providers (nurse practitioners or physician assistants) are specialty-trained in performing urodynamics, and will help your child through his or her urodynamics test.
Urodynamics is a set of tests used to measure how your child's bladder functions, including how it fills, squeezes, opens and empties. Urodynamics can also diagnose problems such as bladder overactivity or a small-sized bladder. The body structures involved include the bladder, as well as the urethra and the muscles of the pelvic floor.
If your child's bladder has problems with storing or emptying urine, this may cause urinary wetting, difficulty potty training or an inability to pee completely. Severe bladder dysfunction can cause repeated urinary tract infections, damage to your child’s bladder and/or damage to your child’s kidneys. Sometimes poor bladder function can only be seen by performing urodynamics studies (or tests).
Your child's health care providers will use information gained from urodynamics to create a plan for your child. In some cases, he or she may need medication(s), regular bladder catheterization (“CIC”) and/or surgery to protect the bladder and kidneys.
Conditions for Urodynamics
Types of Tests
Your child's health care provider will evaluate his or her situation and determine which urodynamics tests may be appropriate. Tests include:
- Uroflometry (Uroflow) – How fast your child pees
- Electromyelogram (EMG) – How well the pelvic floor muscles (muscles that help hold in urine) work
- Cystometrogram (CMG) – Tests if your bladder stores urine at normal pressures and how well your child senses a full bladder
- Voiding pressure study – How fast your child pees and with what pressure
- Postvoid residual (PVR) – If your child empties their bladder after peeing
- Video fluoroscopy – A real-time X-ray study is performed while putting contrast fluid into the bladder. It shows the shape of the bladder, bladder neck and urethra during filling and emptying. It can also diagnose backflow of urine to the kidneys called “vesicoureteral reflux” which is one cause of urinary tract infections.
