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.
How the Test is Performed:
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.
How to Prepare for the Test
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.
How the Test Will Feel The test involves normal urination, so you should not experience any discomfort.
Why the Test is Performed
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.
What Abnormal Results Mean
Results are compared with your symptoms and physical exam. A result that may need treatment in one patient may not need treatment in another patient.
Several circular muscles normally regulate urine flow. If any of these muscles becomes weak or stops working, you may have an increase in urine flow or urinary incontinence.
If there is a bladder outlet obstruction or if the bladder muscle is weak, you may have a decrease in urine flow. The amount of urine that remains in your bladder after urinating can be measured with ultrasound. Your health care provider should explain and discuss any abnormal results with you.
There are no risks with this test.
