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.
Typically, urine flow runs from 10 ml to 21 ml per second. Women range closer to 15 ml to 18 ml per second. A slow or low flow rate may mean there is an obstruction at the bladder neck or in the urethra, an enlarged prostate, or a weak bladder.
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.
