For some years now Botulinum toxin preparations like Botox have been used for overactive bladders. Symptoms experienced by patients with overactive bladder include urinary urgency and treatment normally involves restricting bladder irritants such as caffeine, alcohol and doing pelvic floor exercises. Oral medications have been helpful as well. Injecting the bladder with Botulinum toxin has been successful in patients with a neurogenic bladder. The effects seem to last for six months and certainly reduces the number of incontinent episodes. This is another welcome successful use for Botox outside of cosmetic surgery. A recent study from Leeds University suggests that for patients with an overactive bladder or a neurogenic bladder, this would be of considerable benefit.
