WHAT IS URINARY FLOW TEST?
Urinary flow test is a diagnostic screening procedure used to calculate the flow rate of urine. For this test, you will urinate into a special funnel that is connected to a flow meter. 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.
During normal urination, the initial urine stream starts slowly, but almost immediately speeds up until the bladder is nearly empty. The urine flow then slows again until the bladder is empty. In persons with a urinary tract obstruction, this pattern of flow is altered, and increases and decreases more gradually. The uroflowmeter graphs this information, taking into account the person’s gender and age.
Results from the test can help your doctor determine how well your bladder and sphincter are functioning. 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 weakened bladder or an enlarged prostate.
