Answer: C) Sacral nerve stimulation
Explanation: interstitial cystitis can be simply refered to as a non infectious painful bladder condition which may be chronic depending on the severity. Some of the symptoms include pelvic and bladder pain as well as an urge to frequently urinate.
The best treatment that Allison's doctor is likely to recommend to her is the sacral nerve stimulation. Reducing the urgency to urinate which is associated with interstitial cystitis is the main target of this nerve stimulation technique, it involves simulating the sacral nerves which are the primary link between the spinal cord and nerves in the bladder. In this technique, electrical impulses are sent to the bladder by a thin wire which will be placed near the sacral nerves, this will help to reduce some of the symptoms.
