If you have a problem with urine leakage or blocked urine flow, our Urology Department may be able to help. One of the tools they may use to evaluate the cause of your symptoms is urodynamics.

Urodynamic testing allows us to evaluate the urinary tract, which typically consists of two kidneys, two ureters, a bladder, and a urethra. Kidneys filter out waste from the bloodstream, which produces urine. The urine travels to the bladder from the ureters which connect to the kidneys. The urethra allows urine to exit from the bladder. The bladder is a dynamic spherical muscle that stores and releases urine. A normal bladder should be able to hold 16 ounces for about 2 to 5 hours.

Urodynamic testing allows us to evaluate the storage and release of urine. Reasons for evaluation include:

  • Urine leakage
  • Frequent urination
  • Painful urination
  • Sudden, strong urges to urinate
  • Problems starting a urine stream
  • Problems emptying the bladder completely
  • Recurrent urinary tract infections
  • Pelvic organ prolapse

Urodynamic testing at Sansum Clinic consists of precise measurements using pressure monitors to record the pressures inside the bladder, and sensors record muscle and nerve activity. The urodynamic test results help diagnose the cause and nature of a lower urinary tract problem. The testing does not involve special preparations.

Urodynamic tests include:

  • Uroflowmetry
  • Postvoid residual measurement
  • Cystometric test
  • Leak point pressure measurement
  • Pressure flow study
  • Electromyography

After the test has been completed, one may feel mild discomfort for a few hours when urinating. Staying hydrated may help to reduce the discomfort. An antibiotic is typically given the day of the testing to help prevent infection. Precautions are taken to reduce the risk of a urinary tract infection with the testing.

Results are available immediately, and the testing is very interactive. Patients can learn a lot about their symptoms during the testing. Testing can be crucial to treatment options and prognosis.
