Injection of botulinum toxin A may be performed by means of either rigid or flexible cystoscopy. Various different endoscopic needles may be used for the injection, in particular ultrafine 4-mm flexible needles that may be passed through the flexible cystoscope. Besides the 4-mm flexible needle, the needle used for collagen injection and the needle used for dextranomer or hyaluronic acid injection have also been used for this procedure.
