Uroflowmetry is a test that measures the volume of urine released from the body, the speed with which it is released, and how long the release takes.
You will urinate in a special urinal or toilet with a machine that has a measuring device.
You will be asked to begin urinating after the machine has started. When you finish, the machine will create a report for your health care provider.
Your health care provider may ask you to temporarily stop taking medications that can affect the test results.
Uroflowmetry is best done when you have a full bladder. Do not urinate for 2 hours before the test. Drink extra fluids so you will have plenty of urine for the test.
Do not place any toilet tissue in the test machine.
The test involves normal urination, so you should not experience any discomfort.
This test is useful in evaluating the function of the urinary tract. Usually, a patient having this test will report urination that is too slow.
