Introduction:

Uroflowmetry is widely accepted as a first-line screening tool for voiding function in children. The International Children’s Continence Society reported that adding EMG to uroflowmetry could be useful to interpret the results. This study intended to investigate this testing procedure in healthy children, ultimately leading to the development of a reliable screening tool for voiding dysfunctions.

Material and methods:

A cross-sectional study was conducted including healthy children. Group A performed two direct repetitions of uroflowmetry in combination with electromyography (uroflow/EMG). Group B performed a preceding measurement of isolated uroflowmetry, followed by two randomized measurements of uroflowmetry with and without EMG. Interpretation of uroflow curve was assessor blinded by a pediatric urologist (Austin et al. (2015)) and secondly performed using the flow index methodology (Franco et al. (2016)). Statistical analysis compared different voids within each group and between group A and B.

Results:

Eighty-three children were included and 206 uroflow measurements were obtained. In both groups statistical findings confirmed the hypothesis that it is preferable to perform an additional measurement before the use of uroflow/EMG. Although both groups showed improvement between voids, the group with initial uroflow measurement followed by uroflow/EMG measurement showed more improvement in concern of curve pattern. An initially better first void in group A, but no statistical difference between the second void in group A and uroflow/EMG testing in group B further demonstrates a higher improvement in group B. This suggests the use of a precedent uroflowmetry without EMG is preferable to immediate testing with EMG.

Conclusions:

It should be mandatory to perform one measurement in advance to ensure the reliability of the results. Based on demonstrated results and time- and cost-efficiency, it is suggested to initiate the procedure with a single uroflowmetry measurement followed by one measurement of uroflowmetry with EMG testing.
