To evaluate the prevalence of lower urinary tract complaints and soiling in a cohort of healthy Dutch children, between 5 and 9 years of age.A group of 203 boys and 177 girls was investigated by questionnaire. The questionnaire was based on the validated list of the International Reflux Study Group, expanded with questions on defaecation and soiling. The questionnaire was intended to be filled in by the parents.The total group of 380 children represents a response rate of 60%. Of the boys, 14.3% complain of day-time incontinence, 13.8% have less than three wet episodes a week, and 6.9% have more than three weekly wet episodes; 19.7% of boys has soiling, 3.4% have been treated with laxatives and 6.9% have been treated at least once with antibiotics for urinary tract infection. Of the girls, 12.4% experience day-time incontinence, 11.8 have less than three wet episodes a week, 6.2% have more than three wet episodes weekly; 19.7% show soiling, 2.3% have been on laxatives and 16.9% have been treated for UTIs.With growing proof of a direct connection between LUTS at an older age and LUTS at pediatric age, these RESULTS are of utmost importance. In the near future, they will be needed to convince health care authorities of the necessity to invest money in the treatment of LUTS in children to prevent morbidity at an older age. Pediatric urologists are now faced with the important task of proving that treatment of pediatric LUTS actually prevents LUTS at an older age.
