Sacral Nerve Stimulation Q & A

  • What is Sacral Nerve Stimulation?

    Sacral Nerve Stimulation, also known as sacroneuromodulation, sacral neuromodulation, Axonics procedure, or Interstim procedure is a procedure used to treat symptoms of Overactive Bladder (frequency, urgency, nocturia and urge urinary incontinence), urinary retention and fecal incontinence, who have tried and failed conservative and medical management.

  • How does Sacral Nerve Stimulation work?

    Sacral Nerve Stimulation alters the sacral nerves that go to and come from the bladder. By stimulating these nerves, the brain and bladder can better communicate with each other.

    The device is composed of two parts, the lead wire, and the generator/stimulator. The lead wire is placed near the sacral nerves. This wire is then connected to a generator/stimulator which is implanted under the skin near the buttocks. A handheld device is used to adjust the level of stimulation.

  • What conditions does Sacral Nerve Stimulation treat?

    Sacral Neuromodulation can treat the following conditions:

  • How is Sacral Nerve Stimulation implantation performed?

    Dr. Stone perform will first perform an evaluation phase where he will determine whether or sacral nerve stimulation works for you. The 2nd phase is the implantation phase where implant is placed under the skin. Dr. Stone can perform the evaluation phase in 2 different ways, being either a basic or an advanced evaluation.

    Basic Evaluation

    Dr. Stone performs the first portion of this procedure in the office. It involves the placement of a small temporary wire near the sacral nerve which is then connected to an external generator/stimulator. The wire will stay in place for 2-3 days and then is removed. Based on your response, Dr. Stone will either plan on a full implantation or discuss alternatives with you. The full implantation involves a 45 minute procedure in the operating room. You will be put to sleep and a permanent wire implantation near the sacral nerve which is then connected to a generator which is implanted under the skin. The advantages of this approach is the first portion can be performed in the office. The disadvantage of this approach is that the evaluation phase is short and may not give enough information to make an informed decision on whether to perform the permanent implantation.

    Advanced Evaluation

    Dr. Stone performs both portions of this procedure in the operating room. The evaluation phase involves placement of a wire near the sacral nerve, which is then connected to a external generator/stimulator. This wire can stay in place indefinitely, which allows you and Dr. Stone a longer period of time for evaluation, usually 1-3 weeks. If you experience significant improvement of your symptoms he will then perform the 2nd phase, which is a permanent implant, also in the operating room

    • Pain near incision and implant site

"Dr. Stone has been wonderful. I was very hesitant at first to see a man but he put me completely at ease. I was able to speak to him about my problem with leakage. He discussed several options and gave me choices which I loved. Eventually I decided on surgery. The surgery went well and I finally have my life back again."
