Bladderdysfunction seems to have an increasing frequency in infancy, and especially in children without obvious congenital organic or functional bladderdysfunction. The disorder seems is related with changes in our behaviour, that are stimulated by familial and social pseudo-reasons. Commercial interests and marketing play a major role. This leads to wrong dry-training, an exaggerated hygienic education, prudisheness, wrong toilet-posture, lack of time to void, post-poning, wrong drink- and void-pattern, wrong food-pattern and increasing constipation. Prevention is necessary by an adapted reeducation of parents ans society.
