Overview
You urinate into a receptacle attached to a machine that measures the strength and amount of your urine flow. Test results help determine over time if your condition is getting better or worse. It is important to have a full bladder and a strong urge to go for this test. On a scale of 1-10 where 1 is no urge and 10 is an accident will happen any moment, it is preferable to have an urgency to urinate of 8, 9 or 10.
