Bladder Scan & Flow Rate Test

Instructions: Finish drinking 1 litre of water, 1 hour prior to your appointment time. Do not urinate.

Description of procedure:  You will be asked to arrive at our clinic with a full bladder. The nurse will ask you to urinate into a special toilet that is connected to a computer. As you urinate, the computer prints out results related to the strength, volume, and timing of your urinary stream. When you have completed voiding, the nurse will perform an ultrasound of your bladder to measure how much, if any, urine remains in your bladder after you finish voiding. This appointment takes approximately 10 minutes to complete.


Instructions: No preparation necessary. You may drive yourself to and from the hospital and return to your daily routine immediately after your appointment.  Informed consent will be obtained at the appointment.

Description of procedure: After a local anesthetic (numbing gel) is applied, a small camera called a cystoscope is introduced into the urethra to aid the urologist in checking the bladder and surrounding structures for abnormalities or infection. While this procedure takes only a few minutes to complete, you can expect to be at the hospital for about 45 minutes in total. More information about cystoscopies can be found on our Downloads page.
