The Effect Of Higher Or Lower Voided Volume To Voiding Patterns
PURPOSE To evaluate voiding patterns in children with LUTD have voided volume in uroflowmetry (UF) higher or lower level than expected bladder capasity. MATERIAL AND METHODS Expected bladder capasity was estimated with formula [(age+2)x30ml.]. Voided volumes were assessed during UF which was performed under typical conditions in seperate rooms (MMS 5000 urodynamics system). A total of 60 children with were voided 10% less or more than expected bladder capasity. Their voiding patterns were examined. RESULTS There were not seen any differences in voiding patterns in 38 of 60 children when it was compared with previous voiding patterns which was voided with expected bladder capasity. There were seen staccato voiding pattern in 22 of 60 children had voided volume 10% more than expected bladder capasity who had normal voiding pattern before. Thirteen of these 22 children had (+) EMG activity and remaining 9 0f them had (-) EMG activity. CONCLUSIONS The abnormal voiding patterns in UF with 10% higher expected bladder capasity should be reevaluated with appropriate voided volume. The effect of voided volume higher than expected bladder capasity on EMG needs future investigations.
