Urodynamics is a study allows your Doctor to evaluate the function of the Lower Urinary Tract. This Study assesses how the bladder and urethra are performing their job of storing and releasing urine. Urodynamic tests are performed to gauge symptoms such as:

  • Urinary Incontinence
  • Frequent urination
  • Urinary Retention
  • Loss of urinary control
  • Strong urges to urinate but nothing comes out.


  • Empty your bowels the night before or morning of coming to the office.
  • You should take your normally scheduled medications, unless otherwise directed by your doctor.
  • Wear comfortable clothes and easy shoes to take it off and put back in.
  • Do NOT wear lotion on your legs.
  • You may eat before your appointment.

Let the Technician know:

  • *Allergies to any medications, Iodine, latex.
  • *Had any Valvular or heart implants
  • * Taking blood thinners

During the procedure:

  • You will be instructed to undress from the waist down.
  • Our qualified and competent technicians will review your medical history with you.
  • You will be asked to urinate on a special chair to empty your bladder.
  • A very small catheter is then inserted thru the urethra going all the way to your bladder.
  • Another catheter will be inserted into the rectum.
  • Two patches (like EKG electrodes) will be placed next to your rectum.
  • The catheters and electrodes will then be attached to a computer.
  • Once the program is runs, the machine will start filling your bladder with sterile water.
  • The technician will then ask about the different sensations you are having while your bladder is filling. There are no right or wrong answers to these sensations.
  • Do NOT be afraid if you start to leak urine – we want to determine which specific muscles are not working by causing you to leak during this test.

The complete evaluation may take up to 1 hour.

After the Procedure

You may experience some stinging sensation or light bleeding in your urine after test. We want you to know this is normal. We advise that you drink lots of fluids to help resolve this sensation faster. You will be given a days’ worth of antibiotics as prophylaxis to prevent you from getting an infection. You will be able to resume all previous activities, including driving, upon completion of the test.

In the event, you do develop a urinary tract infection, which is usually manifested as pain, blood and other associated symptoms like fever and chills, please don’t hesitate to call us so we can further assist you and prescribe the necessary antibiotics.
