Overactive bladder (OAB) is defined as urgency, with or without urge incontinence, usually with frequency and nocturia.1 It is a common condition with a significant impact on the quality of life.2 There are two primary approaches to the treatment of OAB; behavioral interventions and pharmacologic therapies. Both have been shown to produce significant reduction of OAB symptoms in large numbers of patients. © 2008 Springer-Verlag London.
