Many papers report the clinical success of botulinum toxin A as a method of management of various bladder dysfunctions. The rationale was that botulinum toxin A was able to block the presynaptic release of acetylcholine from the parasympathetic efferent nerve. The efficacy might result not only from an inhibitory effect on detrusor muscle, but also some effects might be mediated by altering the afferent nerve input. This systematic literature review discusses the efficacy and safety of botulinum toxin A therapy for idiopathic detrusor overactivity, neurogenic detrusor overactivity, interstitial cystitis/painful bladder syndrome and benign prostatic hyperplasia. The information was gathered from a PubMed literature research for abstracts from recent urological meetings. Injection of botulinum toxin A appears to have a positive therapeutic effect in multiple urological conditions, such as refractory idiopathic detrusor overactivity, neurogenic detrusor overactivity, interstitial cystitis/painful bladder syndrome and benign prostatic hyperplasia. Because the United States Food and Drug Administration has approved botulinum toxin A (Botox) for injection for the treatment of urinary incontinence as a result of neurogenic detrusor overactivity (e.g. spinal cord injury, multiple sclerosis) in adults who have an inadequate response to or are intolerant of an ant cholinergic medication, the use of botulinum toxin A will spread and be a more familiar therapy in the urological arena. However, further robust evidence should be awaited. We will discuss the current use of this agent within the urological field.
