    UROFLOWMETRY

    WHAT IS UROFLOWMETRY?
    Uroflowmetry is an assay that measures the volume of urine released from the body, the speed with which are released, and the time needed to release them.

    HOW IS THE TEST DONE?
    The patient urinates into a special toilet bowl connected to a measuring device.
    You will be asked to begin urinating after booting. When finished, the machine will generate a report for your urologist.

    HOW TO PREPARE FOR THE TEST?

    • Your doctor may ask you to temporarily stop taking medications that can affect the test results.
    • The test is best done when you have a full bladder. Do not urinate for 2 hours before the test. Drink extra fluids to fill the bladder for the test.

    HOW DOES UROFLOWMETRY FEELS LIKE?
    The test involves normal urination, so you will not experience any discomfort.

    WHY HAVE A UROFLOWMETRY?
    This test is useful in evaluating the urinary system. It will help your urologist to objectify the symptoms you mention and to make decisions about your treatment.

    WHAT ARE THE NORMAL RESULTS?
    Normal values vary with age and gender. In men, the urinary flow decreases with age. Women have less change with age.
    Ages 14-45

    • The average flow rate for males is 21 mL / sec.
    • The average flow rate for females is 18 mL / sec.

    ages 46-65

    • The average flow rate for males is 12 mL / sec.
    • The average flow rate for females is 18 mL / sec.

    Ages 66-80

    • The average flow rate for males is 9 mL / sec.
    • The average flow rate for females is 18 mL / sec.

    WHAT DO THE ABNORMAL RESULTS MEAN?
    The results are compared with your symptoms and physical examination. A result that may need treatment in a patient may not need treatment in another patient.
    If there is a blockage of the outlet of the bladder or the bladder muscles are weak, you can have a reduction in urine flow. The amount of urine remaining in the bladder after micturition can be measured by ultrasound.
    Your doctor should explain any abnormal results.
