This procedure is performed for the treatment of overactive bladder. Local anesthesia is placed into the bladder through a small catheter and allowed to remain for 15-20 minutes to take effect. A cystoscope is placed into the bladder in order to visualize the bladder wall. Several injections of botulinum toxin (Botox) are made throughout the bladder wall intended to weaken and/or paralyze the bladder muscle. The procedure takes approximately 15-20 minutes but expect to be at the appointment for one hour. You will start a 5 day course of antibiotics the day prior to the procedure and take a valium or similar sedative medication one hour prior to the procedure so need to have a driver to and from the office. After effects may include slight urgency to urinate and burning with urination for a few hours, as well as possible blood in the urine that clears quickly. It takes 5-7 days to see the maximum effects from the injections.
