These studies are used to assess how the bladder and urethra are performing their job of storing and releasing urine. Urodynamic tests help your doctor see how well your bladder and sphincter muscles work.

  • Cytometric test monitors how the pressure builds up in the bladder as it fills with urine; the amount of urine the bladder can hold; and at what point you feel the urge to urinate.
  • Electromyography is included in the cytometric testing if nerve or muscle damage is suspected. Sensors are placed on the skin to measure electrical current created when the pelvic floor muscles contract.
  • Video urodynamic test combine cytometry and cystography into a single test. Pictures and videos of the bladder during filling and emptying are taken. This test shows the size and shape of the bladder and provides useful information about the function of the bladder and urethra.

After urodynamic tests, there might be mild discomfort with urination for a few hours. You may also experience a small amount of blood in the urine due to the catheter. Drinking (16) ounces of water every hour for 2 hours may help with symptoms. Taking a warm bath or holding a warm, damp washcloth over the urethral opening may be recommended by your healthcare provider. If any symptoms of infection are noticed such as fever, chills, or pain, call your healthcare provider.

Tests results are available after the tests are completed and will be discussed with you when you see your provider.
