Uroflowmetry is a quick, simple diagnostic screening test that is used to calculate the flow rate of urine over time. The test measures the volume of urine released from the body, and the speed and time of urinary release. The doctor may conduct a uroflowmetry if patient reports symptoms of slow urination or urination difficulties, or to detect the presence of problems with the lower urinary tract, such as:
- Benign prostatic hypertrophy
- Prostate cancer, or a bladder tumor
- Urinary incontinence
- Urinary blockage
- Neurogenic bladder dysfunction
- Frequent urinary tract infections
The uroflowmetry is a painless and noninvasive procedure that will help the doctor diagnose symptoms such as pain during urination or urinary incontinence. The procedure is conducted in a private testing room and the visit will last less than 30 minutes.
The trained medical technician will instruct patient on how to operate the uroflowmetry device and patient will be asked to urinate into a funnel-shaped device connected to an electronic uroflowmeter. During the procedure, patient will be required to remain still. It is best to urinate as normally would, without pushing or straining the speed or flow in any way. The electronic uroflowmeter will then measure the speed and quantity of urination.
Before the test, be sure to drink plenty of water to ensure a full bladder. It is recommended that patient informs the doctor if patient is pregnant, and if patients are on any medication. The doctor may ask patient to temporarily stop taking any medication that may affect the test’s accuracy.
