Refers to a diagnostic test used to measure the flow of urine during urination.
The speed of urine flow is measured electronically and the flow rate is calculated as milliliters of urine passed per second.
Average and maximum flow rates can be measured.
Testing occurs with a comfortably full bladder.
Patients urinate into a funnel connected to the electronic uroflowmeter, which records data about the urine flow on a flow chart.
The peak flow rate, also known as Qmax is generally used as the basis for determining the severity of any blockage or obstruction.
Low flow may indicate such conditions as obstruction of the urethra, enlarged prostate or poor bladder function.
