[Urodynamics in diagnosis and therapy of "enuresis"--relevance for child and adolescent psychiatry].

Enuresis and functional urinary incontinence are clinically and pathophysiologically heterogeneous disorders. They differ with regard to their urodynamics, i.e. with regard to the function or dysfunction of the urinary tract. In addition to general measures such as history, physical examination, urinalysis, questionnaires and flow charts, noninvasive sonography and uroflowmetry with pelvic-floor EMG play an important role in diagnosis and therapy. Rates of pathological findings are especially high among day-wetting children and nocturnal enuretics with micturition problems. This group requires a detailed diagnosis, especially children with detrusor-sphincter discoordination, which can be treated effectively by means of uroflow-biofeedback. The relevance of these methods in child and adolescent psychiatry are discussed in detail and practical recommendations are made.
