**1. Introduction**

Disorders of bladder and bowel control are among the most common problems in childhood. At the age of 7, 10% of children get wet during the night, 2 to 3% wet their clothes during the day, while 1 to 3% of children have fecal incontinence [1]. These disorders often occur together. Despite a high rate of spontaneous remission, 1 to 2% of adolescents have nocturnal enuresis and less than 1% have daily urinary incontinence or fecal incontinence [2]. Most of these disorders are functional, i.e. they are not caused by neurological, structural, or medical factors.

Functional voiding disorders are some of the main causes of daily wetting in children, the development of recurrent urinary tract infections and vesicoureteral reflux (VUR). In addition to the risk of developing structural changes in the bladder wall and upper urinary tract, voiding disorders, accompanied by urinary incontinence, can be a severe psychosocial problem. Children describe wetting at school as the third most stressful event in life after the death of a parent and loss of sight [3]. It is evident that urinary incontinence causes significant psychological morbidity, and treatment is crucial.

Functional voiding disorders can be treated in a number of ways, including pharmacological therapy, urotherapy, and surgical treatment in the most severe cases.
