Simplified bladder botulinum-toxin delivery technique using flexible cystoscope and 10 sites of injection.

Recently, the use of botulinum toxin A has been extended to patients with non-neurogenic urologic disorders such as refractory idiopathic overactive bladder. We describe a modification of our original injection technique that allows one to deliver botulinum toxin into the bladder quickly and efficiently in an office setting with reliable results and no local or systemic side effects.
