Voiding patterns in incontinent children aged 6-11 years show wide variation. Age significantly impacts voided volumes, but gender and incontinence type do not, according to frequency-volume chart data.

Area of Science:

  • Pediatric Urology
  • Clinical Research
  • Bladder Function

Background:

  • Urinary incontinence is common in children, affecting their quality of life.
  • Frequency-volume charts (FVC) are essential tools for assessing voiding patterns.

Purpose of the Study:

  • To determine the mean and standard deviation of voiding variables in incontinent children aged 6-11 years.
  • To analyze the influence of incontinence type, gender, and age on these voiding parameters.

Main Methods:

  • Data collected from 3 years of routine FVC assessments at two continence clinics.
  • Voided volume and voiding interval data analyzed for mean maximum, mean minimum, and overall mean values.
  • Multivariate analysis performed to identify influencing factors.

Main Results:

  • Voiding patterns in incontinent children exhibit significant variability with large standard deviations.
  • Child's age was the only significant factor influencing voided volume parameters.
  • Gender and type of incontinence (day vs. nocturnal) did not affect bladder storage patterns.

Conclusions:

  • Voided volumes and their standard deviations vary widely among incontinent children.
  • Age is the primary determinant of voiding volume trends in this population.
  • High variability necessitates consideration of standard deviation in sample size calculations for FVC studies in children.
