Abstract:
Overactive bladder is a prevalent condition with bothersome symptoms that greatly impact health-related quality of life. Despite a multitude of treatment options, many patients go untreated or undertreated. This article addresses the contemporary management of overactive bladder, including behavioral and lifestyle modifications, pelvic floor muscle therapy, biofeedback, drug therapy, neuromodulation, and botulinum toxin.
