A urinary frequency-volume chart can be useful in assessing patients with LUTS. The patient should record on the urinary frequency-volume chart for a minimum of three days, charting time and volume of voids and including any episodes of incontinence.

Add up the volume of all voids overnight, including the first void of the morning, and divide this figure by the total voided volume in that 24-hour period.
