Urodynamics is a general term used to describe tests that are performed to look at the bladder’s ability to fill, store, and empty. The goal is to measure and explain what is happening in and around the bladder with the goal of forming and managing a treatment plan for good bladder health.

During the test, a small straw (catheter) is placed into the bladder and another into the rectum. Electrode stickers are placed on the skin to watch the muscles nearby squeeze. A computer watches the change in pressure as fluid fills the bladder through the catheter. X-ray images may be taken to see the bladder and surrounding structures.

Urodynamic testing helps to determine:

  • How much urine a child’s bladder holds
  • What happens in a child’s bladder as it fills with urine
  • How the muscles that help hold urine in the bladder and help control urination work
  • What happens in a bladder as the child urinates
  • How to best manage problems with wetting
  • Changes in bladder function from year to year
  • Risks for developing kidney problems in the future

Testing may also include uroflowmetry, or uroflow evaluation. A uroflow evaluates the urinary stream, flow pattern, and the bladder’s ability to completely empty. The patient has stickers applied to the belly, bottom, and knees. The patient then urinates into a special toilet that is connected to a computer. The information is used to help determine the course of treatment.
