These percent values are found in the patient statistics of the Voiding Summary printout. The M% represents the
male values and the F% represents the female values.
The comparison with normal parameters should not be used for diagnostic purposes. It is
recommended to repeat the study if the total voided volume is less than 55 ml; normal parameters
are not available below this volume. Statistic values cannot be given if the voided volume is less than
55 cc and more than 555 cc.
Parameters of urinary flow were
analyzed from 150 curves from subjects between 20 and 40 years old.
The minimum normal for a given volume appears to
be the most practical value with which to
compare patient flow rate.
