Video-urodynamic studies of minor voiding dysfunctions in children: an overview of 13 years' experience.

By the definition 'minor voiding dysfunctions' is understood children with a history of frequency, urgency, daytime wetting, squatting, and infrequent voiding, singly or in combination. Urinary tract infections (UTI) are often present but symptoms must also be present when the children are free of infection. The upper urinary tract is generally normal or has minor anomalies. Any evidence of infravesical obstruction, frank or occult neurogenic bladder, or emotional disturbances must be excluded. In this study we report 13 years' experience of video-urodynamic evaluation in children with minor voiding dysfunctions, with special reference to clinical information, morphofunctional correlations, relationship with recurrent UTI, vesico-ureteric reflux and dilatation of the upper urinary tract. According to our experience we estimate that about 60% of the patients evaluated in this study would not require a video-urodynamic evaluation today.
