When recording daily urine volumes for the frequency–volume chart, a patient must measure voided urine volume throughout the whole day. Unless the patient stays at home, the conventional 500‐mL paper or plastic cup must be carried with at all times, which can be very embarrassing and troublesome for the patient, so a collapsible, portable measuring cup has been developed. To determine the measuring accuracy of the new cup, the visual estimate was compared with the actual volume. The cup was found to be a highly accurate and useful container for measuring voided urine volume.
