Voiding symptoms are classified as hesitation, straining, weak stream, and intermittency.

Constipation and/or fecal incontinence are closely related to LUTD, among children over 5 years due to functional or nonorganic causes.

The exact prevalence of the lower urinary tract dysfunction (LUTD) is unknown, approximately 20% to 30% of children in the world have symptoms associated with voiding disorders. In epidemiological studies, this ratio is between 2.1% and 19.2% in school-age children.Due to the modern lifestyle, the prevalence increases secondary to changes in toilet training and habits.
