Anticholinergic drugs versus non-drug active therapies for overactive bladder syndrome in adults.

Overactive Bladder Syndrome (OAB) is defined as urgency, with or without urgency incontinence, usually with frequency and nocturia. Pharmacotherapy with anticholinergic drugs is often the first line medical therapy, either alone or as an adjunct to various non-pharmacological therapies. The commonest non-pharmacologic therapies are: bladder training, pelvic floor muscle training with or without biofeedback and electric stimulation to affect detrusor muscle activity.
