Interstim for Bladder Control

dr gousse
If you suffer from any of the symptoms of overactive bladder, you’re not alone. It is estimated that more than 33 million Americans suffer from OAB. If you are not responding to the orla medications (antimuscarinics) sacral neurostimulation (Interstim)  may be an option to help you manage your symptoms.

The uniqueness of Interstim is that it offers a trial period before the device is implanted. The trial assessment takes 3- to 7-days and lets you try neurostimulation to see if it is right for you without making a long-term commitment.

Dr Gousse will help you determine whether neurostimulation is right for you. The treatment is designed to minimize the symptoms of overactive bladder..

Here’s how it works

The exact mechanism by which  Interstim works is not known. The first stage of the procedure ( called peripheral sacral nerve evaluation (PNE)  may be performed in the office or the operating room, depending on the case. Dr Gousse will numb a small skin  area and insert a thin, flexible wire you’re your  sacral nerves (near your tailbone). . During the PNE, you will be awake in order the guide proper placement. You will be asked where you feel the nerve stimulation in your body. Dr Gousse will also note some muscle contactions in your body to guide proper placement. Typically, you will be in the prone position ( laying on your stomach ). This position  allows access to the tail bone and anal area.

Once proper placement is confirmed, the electrical  wire is taped to your skin and connected to a small  external stimulator ( resembling a large beeper ) which you’ll wear on your waistband. The external stimulator sends mild electrical pulses through the wire to a sacral nerve. Electrical shock or severe nerve damage associated with the therapy  has virtually never been reported. The stimulation may help improve your bladder function or get it working the way it’s supposed to.

You’ll be asked to document your urinary symptoms which led to the implant . If your symptoms are significantly reduced or eliminated during the trial, you and Dr Gousse can discuss long-term neurostimulation therapy.

Dr Gousse  or nurse will give you information about operating the test stimulator. He or she will also tell you about any precautions or activity restrictions related to the trial assessment.

Long-term sacral nerve stimulation therapy involves placement of an implantable pulse generator-battery  ( size of stop watch ) under  the fatty tissues of the upper buttock area. Typically this step ( step2, battery implant  ) ,  done only  after the trial test ( step 1 ) is shown to be successful,  is performed in the operating room under local  or general  anesthesia. The half life of the battery varies according to usage and type and may last 3 to 8 years. Once the entire system is in place, there are no visible wires or batteries outside of the body. One can regain a normal life without limitations. A few patients may experience discomfort  at the battery implant site.

The results of neurostimulation vary from person to person. Although very useful, this treatment option is not a cure for bladder control problems; however, it may help relieve your symptoms.
