Functional daytime incontinence: non-pharmacological treatment.

In children with 'functional incontinence', defined as any form of (daytime) wetting caused by non-neuropathic bladder/sphincter dysfunction, most signs and symptoms are rooted in habitual non-physiological responses to signals from bladder and urethra. These responses develop at toddler age, when children learn how to remain dry. Once they have become a habit, incomplete bladder emptying and recurrent urinary tract infections come into play, reiterating the non-physiological responses into fixed patterns of bladder/sphincter dysfunction with functional incontinence as the leading symptom. Non-pharmacological treatment of functional incontinence implies relearning and training the normal responses to signals from bladder and urethra: a cognitive process, with perception of the signals reinforced by biofeedback. This type of treatment is best combined with long-term chemoprophylaxis. Severe cases will benefit from anticholinergic drugs, as adjuvants to the training programme. Urodynamics play a crucial role in documenting the specific patterns of incontinence and in providing biofeedback. For a successful programme, psychological screening of the children is indispensable.
