Uroflowmetry is performed by having a person urinate into a special funnel that is connected to a measuring instrument. The measuring instrument calculates the amount of urine, rate of flow in seconds, and length of time until completion of the void.

How do you prepare for Uroflowmetry?

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. The test is the most accurate if you urinate at least 5 ounces (150 milliliters) or more.

Is Uroflowmetry test painful?

During Your Uroflowmetry

You should not experience any pain or discomfort from the procedure. The uroflowmeter will record your urine output and flow rate on a chart. Try not to push or strain as you urinate. In some cases, you may be asked to perform the test on several consecutive days.
