Uroflowmetry measures the flow of urine. It tracks how fast urine flows, how much flows out, and how long it takes. It’s a diagnostic test to assess how well the urinary tract functions. Your doctor may suggest uroflowmetry if you have trouble urinating, or have a slow stream.
Unlike traditional urine tests in which you urinate into a cup, you’ll need to urinate into a funnel-shaped device or a special toilet for the uroflow test. It’s important that you don’t put any toilet tissue on or in the toilet or device. It’s best to urinate as you normally would, without attempting to manipulate the speed or flow in any way. An electronic uroflowmeter hooked up to the funnel or toilet measures the speed and quantity of urination. You must refrain from urinating until the machine is turned on.
You’ll need to give a urine sample. It may seem awkward or uncomfortable, but you shouldn’t experience any physical discomfort during the test. Be sure to arrive at your doctor’s office with a full bladder. Ideally, you shouldn’t urinate for several hours before the appointment. You should drink plenty of liquids to make sure you have enough urine for the test.
Your doctor may recommend a uroflow test if you have slow urination or difficulty urinating. They may also use the test to determine how well your urinary tract and sphincter muscle are functioning. The sphincter muscle is a circular muscle that closes tightly around the bladder opening. It helps to prevent urine leakage. Results from the test can help your doctor determine how well your bladder and sphincter are functioning. It can also be used to test for obstructions in the normal flow of urine. By measuring the average and maximum rates of your urine flow, the test can estimate the severity of any blockage or obstruction. It can also help identify other urinary problems, such as a weak bladder or an enlarged prostate.
You will urinate in a urinal or toilet fitted 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 make a report for your health care provider. How to Prepare for the Test.
