MEASUREMENTS DEFINITION NORMAL RESULTS
Voiding Time Total duration of the
micturition, including
interruptions.
Averages about 10
seconds with 100 ml
voided volume and 25
seconds with 400 ml
voided volume. No
“normal limits” defined.
Flow Time Total duration of
measurable flow.
Equal or nearly equal to
voiding time. A flow time
that is significantly shorter
than the voiding time
indicates an abnormal
intermittent FloPoint
®
Elite
pattern.
Time to Peak Flow Time from flow onset to
peak flow.
About 30 percent of
voiding time. Has no
clinical significance with
irregular flow pattern.

Elite Curve Patterns
Time to peak flow rate, flow time and voiding time do not provide the same quantitative
“normal” versus “abnormal” results as do flow rates. However, as discussed in the next
section, these measurements can provide useful indications of the FloPoint
®
Elite curve’s
shape.
Continuous/Regular Patterns:
 Normal: A normal FloPoint
®
Elite pattern is a smooth unbroken, bell-shaped
curve with peak flow occurring relatively early. (Time to peak flow averages
about 30% of total flow time.) Figure 34 shows an example of a normal
uroflow curve.
