Tonsillectomy does not improve bedwetting: results of a prospective controlled trial.

Purpose: Sleep disordered breathing caused by tonsillar hypertrophy has been implicated as a cause of primary and secondary nocturnal enuresis in children. We prospectively studied the preoperative and postoperative rates of nocturnal and daytime incontinence in a group of children with tonsillar hypertrophy undergoing tonsillectomy compared to a matched control group undergoing surgery unrelated to the airway or urinary tract.

Materials And Methods: A total of 326 toilet trained children 3 to 15 years old were included, with 257 in the tonsillectomy group and 69 in the control group.
