Urodynamic Evaluation

Urodynamic evaluation refers to a series of tests used to assess the function of the lower urinary tract by measuring various aspects of urine storage and evacuation. This testing is standard for patients who experience urinary incontinence, the involuntary loss of bladder control.

Components of the test include the following:

  • Complex cystometrics, which evaluate bladder function by measuring pressure and volume in the bladder during filling, storage, and voiding (urinating).
  • Uroflowmetry, which measures the rate of urine flow.
  • Urethral pressure profile, which measures urethral and sphincteric function.
  • Leak point pressure, which measures the abdominal pressure at which leakage occurs. This is measured by having the patient cough or "bear down," and determining the point at which leakage occurs.
