Urodynamics is a series of diagnostic tests that evaluate the function of your bladder and urethra. These tests may be recommended if you have urinary incontinence (leakage of urine), neurogenic bladder, recurrent bladder infections, slow or weak urinary stream, incomplete bladder emptying, or frequent urination. Urodynamic studies help your doctor determine the source of bladder control symptoms and the best course of treatment.

Your doctor will decide which of the following diagnostic tests should be performed to help diagnose and treat your bladder control symptoms:

  • Uroflow: Measures the speed and amount of urine you void
  • Cystometrogram: Evaluates how your bladder holds urine, measures your bladder capacity, and also determines how well you can control your bladder
  • EMG: Measures how well you can control your sphincter muscles and determines if they are working in coordination with your bladder, and EMG patches may be placed near your rectum to record muscle activity
  • Pressure flow study: Determines if there is an obstruction in your bladder or urethra
  • Videourodynamics: This study is a combination of the above tests with the addition of video pictures which uses contrast dye to visualize the bladder

About Urodynamic Studies

Your urodynamics appointment will take approximately 60 minutes. A urodynamicist will guide and support you throughout your testing, answer any questions you may have, and ensure your physical and emotional comfort. You will be asked to arrive at your appointment with a comfortably full bladder for testing.
