Testing for Urinary Incontinence

Urodynamic tests for urinary incontinence are measurements taken to evaluate your bladder’s function and efficiency. Some urodynamic tests are relatively simple and can be done in a doctor’s office. For a basic Cystometrogram (CMG):

  • You will be instructed to arrive for testing with a full bladder.
  • While you urinate into a container, the volume of urine and the rate at which the bladder empties are measured.
  • A thin, flexible tube (catheter) is then inserted into the bladder through the urethra, and the volume of any urine remaining in the bladder is measured (post-void residual, or PVR). A slight burning sensation may occur when the catheter is inserted.
  • The bladder may be filled with water through the catheter until you have the first urge to urinate. The amount of water in the bladder is measured at this point. Then more water may be added while you resist urinating until involuntary urination occurs.

More sophisticated testing uses electrodes placed on the pelvic floor to measure the electrical activity of the muscles while the bladder fills. The appointment will take 30-60 minutes.
