Void
The voiding function is reported as expressed by maximum flowrate together
with voided volume and post-void residual urine in the format:
VOID = Qmax/VV/VRU (Maximum flow/Volume Voided/Residual Volume)
Undetermined values are substituted by a hyphen -. when only the volume is
measured VOID = -/340/-.
Qmax)
The peak flow is the maximum measured value of the flow during micturition.
When a Peak flow marker is present, the peak flow will be the flow at the Peak
flow marker. When no Peak flow marker is present and Flow markers are
present, the peak flow will be the flow at the second Flow marker.
Calculated: Peak flow rate = [F]
Time to Qmax
The time to Qmax is the elapsed time from the onset of the flow to the peak
flow.
Calculated: Time to Qmax = [C]
Voided volume
The voided volume is the total volume expelled via the urethra.
Calculated: Voided volume = [E1+E2+E3+E4]
Flow time
The flow time is the time over which measurable flow occurs.
Calculated: Flow time = [B1+B2+B3+B4]
Voiding time
The voiding time is the total duration of micturition, including the miction
interruptions. When voiding is completed without interruptions, voiding time is
equal to flow time.
Calculated: Voiding time = [D]
Hesitancy
The hesitancy is the time from the moment the investigation is started until the
patient started voiding.
Whenever a Permission to void marker was placed during the investigation,
the hesitancy is calculated as the elapsed time between placement of the
Permission to void marker and the onset of the flow.
Calculated: hesitancy = [A]
