The use of botulinum toxin a in idiopathic overactive bladder syndrome.

Overactive bladder syndrome continues to be a significant burden for the general population. Current first-line medical therapy often includes antimuscarinic medications designed for overactive bladder. Poor efficacy and significant side effects of these antimuscarinic medications have left patients and physicians looking for alternative treatments. There is increasing evidence that intradetrusor injection of botulinum toxin A can effectively treat these patients. We present a current and extensive review of the literature covering the use of botulinum toxin A in patients with overactive bladder with or without idiopathic detrusor overactivity.
