Urodynamics

Capital Region Urology provides specific urodynamic testing procedures that assess how well the bladder, sphincters, and urethra are storing and releasing urine, focusing on the bladder's ability to hold urine and empty steadily and completely. Our urodynamic tests also show whether the bladder is having involuntary contractions that cause urine leakage. Capital Region Urology physicians may recommend urodynamic tests if a patient's symptoms suggest problems with the lower urinary tract. Lower urinary tract symptoms (LUTS) include the following:

  • 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

Urodynamic tests range from simple observation to precise measurements using sophisticated instruments. For simple observation, Capital Region Urology physicians may record the length of time it takes a patient to produce a urinary stream, note the volume of urine produced, and record the ability or inability to stop the urine flow in midstream. For precise measurements, imaging equipment takes pictures of the bladder filling and emptying, pressure monitors record the pressures inside the bladder, and sensors record muscle and nerve activity. We will decide the type of urodynamic test based on the patient's health information, physical exam, and LUTS. The urodynamic test results help diagnose the cause and nature of a lower urinary tract problem.

Most urodynamic tests do not involve special preparations, though some tests may require a patient to make a change in fluid intake or to stop taking certain medications. Depending on the test, a patient may be instructed to arrive for testing with a full bladder.
