Uroflowmetry

Uroflowmetry, also called a uroflow test, measures the flow and force of urine stream during urination. It is a common, noninvasive urinary test used to diagnose symptoms such as pain during urination or urinary incontinence. Results from uroflowmetry can help with assessment of bladder and sphincter function or to test for obstructions in the normal flow of urine.

Uroflowmetry is performed by urinating into a special funnel. This funnel is connected to a measurement device that calculates the amount of urine passed, the rate of flow in seconds and the length of time it takes to completely empty the bladder. During normal urination, the initial urine stream starts slowly, then speeds up, then slows again. This test records any deviation from that norm to assist the physician in making a diagnosis. It can be a valuable tool in planning a course of treatment.

Location
This test is typically performed in a physician’s office.

Time
The procedure usually takes less than 30 minutes.

Preparation
There is no need to fast or adjust your normal food intake prior to the test. Your health care provider may ask you to temporarily stop taking some medications that can affect test results.

You may be instructed to drink several glasses of water in the hours before the test is performed. Please arrive for your appointment with a comfortably full bladder. If you become uncomfortable from the urge to urinate before you are brought into a testing room, please inform the receptionist, who will inform the technician.

During Your Uroflowmetry
You will be taken to a private testing room and asked to urinate into a special funnel connected to an electronic uroflowmeter.  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.

Following Your Uroflowmetry
Typically, there is no special follow-up care required after uroflowmetry. You can resume your daily activities immediately. Your health care provider will contact you regarding the results of your test and any recommendations for treatment.
