    What causes Urinary Incontinence in Children ?
    ### Response:
    Daytime UI can be caused by a UTI or structural problems in the urinary tract. Daytime UI that is not associated with UTI or structural problems is less common and tends to disappear much earlier than nighttime UI. Overactive bladder and infrequent or incomplete voiding, or urination, are common causes of daytime UI.
