InterStim therapy is a medically implanted device that can help individuals who suffer from an overactive bladder and/or bowels. InterStim therapy works by delivering mild electrical pulses to the sacral nerves near the tailbone which initiates communication between the brain and the bowels and bladder. This therapy is known to effectively manage symptoms in individuals who experience a diminished quality of life due to a lack of bladder or bowel control. This procedure typically involves two stages: a trial period where temporary electrodes are placed to assess effectiveness, followed by a permanent implantation if successful. Smith Medical offers a trial procedure and permanent placement.

When is This Procedure Necessary?

Medical professionals may recommend that patients consider an InterStim trial if they have an overactive bladder or bowels and their symptoms do not improve after conservative therapies. Oftentimes, doctors will initially encourage patients to consider lifestyle changes or specific therapies such as bladder training and pelvic floor exercises. Sometimes, medications can also help patients increase urine retention. If these conservative therapies are ineffective, the doctor may recommend that the patient consider an InterStim trial. Approximately 80% of patients experience a noticeable improvement in symptoms with InterStim trials. The majority of patients will opt to undergo a permanent InterStim surgery after the trial period.

What To Expect

Patients are typically under local or general anesthesia to ensure their comfort throughout the procedure. This procedure includes connecting “leads” or wires of the InterStim device to the sacral nerves. The small InterStim device is implanted in the patient’s lower back near the sacral nerves. The device is then connected to an external stimulator where the settings can be adjusted. 

After the procedure, patients may experience some discomfort and swelling in the region of the incision. Oftentimes, doctors will prescribe pain medications for this short period where pain might be present. Patients should communicate with their doctor to report any irregular symptoms.
