Overactive bladder (OAB) syndrome is a condition which affects 16.9% of women and 16.2% of men with a significant negative impact on quality of life. It is a condition characterized by urgency, with or without urge incontinence, frequency and nocturia. Behavioral modifications and oral anti-muscurinic medications are first and second-line therapies for OAB but are frequently ineffective or poorly tolerated. For refractory cases of OAB, onabotulinum toxin can be offered and this therapy was approved by the Food and Drug Administration in January of 2013. In this editorial, we will review the indications, usage, efficacy and safety data for intradetrusor injection of onabotulinum toxin A.
Core tip: Overactive bladder (OAB) remains a highly prevalent and frequently, a recalcitrant constellation of symptoms. For patients who are refractory to oral medical therapy, there is sufficient level I evidence to support the use of onabotulinum toxin A injection therapy. It is a safe and very effective 2nd line treatment for OAB, even in the elderly population. The suggested Food and Drug Administration approved dose is 100 U to maximize the benefits and minimize the adverse effects of this therapy. Risks of the intradetrusor injection of onabotulinum toxin A include urinary tract infection, increased post void residual, urinary retention which may lead to necessity of self catherization for a period of time.
