[Enuresis--symptom of delayed micturition development or an obstructive urinary tract anomaly?]

In a review of the literature the question of origin of enuresis was studied. Most authors agree that diminished bladder capacity and involuntary detrusor contractions are the main cause of primary enuresis. Urodynamic investigations are necessary to differentiate developmental delay in bladder function form true anatomic infravesical obstruction. Therapeutic measures are successful in 2/3 of enuretics. Enuresis has a great tendency of spontaneous disappearance around 15% per year.
