Summary: Urinary incontinence in children is a common condition with a complex, multifactorial etiopathogenesis. According to the ICCS classification, urinary incontinence is divided into continuous and intermittent forms, as well as daytime and nighttime incontinence. Continuous urinary incontinence occurs in children of all ages and is associated with congenital anomalies of the urogenital tract or neurogenic disorders, whereas intermittent daytime incontinence is diagnosed in children aged ≥5 years. This article provides a detailed discussion of continuous and daytime urinary incontinence. The causes of this type of incontinence include overactive and underactive bladder, dysfunctional voiding, Hinman syndrome, giggle incontinence, delayed voiding, Bladder and Bowel Dysfunction and vesicovaginal reflux. Daytime urinary incontinence is most often functional in nature, with additional contributing factors such as improper and/or delayed toilet training, incorrect voiding posture, and habits that promote constipation, including insufficient fluid intake, an inadequate diet, and a sedentary lifestyle. These factors are modifiable, which makes their recognition particularly important when planning treatment. It should be emphasized that long-lasting urinary incontinence is not only a risk factor for developing urinary tract infections but also a significant source of psychosocial problems. For most children, the diagnostic process and initial management should be undertaken by primary care physicians and pediatricians. Continuation of care should involve close collaboration with pediatric specialists, such as pediatric nephrologists and urologists, as well as psychologists.
