Detrusor overactivity is the most common voiding dysfunction in children. This condition is also known as overactive bladder (OAB), urge syndrome, hyperactive bladder syndrome, persistent infantile bladder, or detrusor hypertonia [1]. Idiopathic OAB is defined by the International Continence Society (ICS) as a complex symptom of urinary urgency, which may or may not be associated with urgency urinary incontinence, urinary frequency, and nocturia in the absence of pathological or metabolic factors [2]. As the OAB symptomatology is concerned, the International Children’s Continence Society (ICCS) states that Urgency incontinence is often also present, as the increased voiding frequency, but these symptoms are not necessary prerequisites for the use of the term OAB [3]. The OAB in children is characterized by involuntary detrusor contractions and urethral instability [4]. The etiology has been variously ascribed to maturation delay, prolongation of infantile bladder behavior, or shortening of acquired toilet-training habits [5]. Early diagnosis and appropriate treatment could affect upper urinary tract function and drainage and ultimate bladder functions.
