What Is InterStim?

Are you curious to know what is InterStim? You have come to the right place as I am going to tell you everything about InterStim in a very simple explanation. Without further discussion let’s begin to know what is InterStim?

In the realm of medical advancements aimed at improving quality of life, InterStim emerges as a groundbreaking therapy offering relief to individuals struggling with bladder and bowel control issues. This innovative treatment represents a beacon of hope for those affected by conditions such as urinary incontinence and fecal incontinence. Let’s delve into the essence of InterStim, its applications, mechanisms, and the transformative impact it has on patients’ lives.

What Is InterStim?

  1. Definition: InterStim, short for “intermittent stimulation,” is a neuromodulation therapy designed to address urinary and fecal incontinence by modulating the nerves that control bladder and bowel function.
  2. Neuromodulation Technique: It involves the use of a small device implanted near the sacral nerves, delivering controlled electrical pulses to regulate nerve activity and improve bladder or bowel control.

Mechanism Of Action

  1. Targeted Nerve Stimulation: The InterStim device delivers mild electrical pulses to the sacral nerves, which influence the bladder, bowel, and pelvic floor muscles, helping control the sensation and function of these organs.
  2. Regulating Nerve Signals: By modulating nerve signals related to urinary and bowel function, InterStim aims to restore proper communication between the brain and the pelvic nerves, reducing symptoms of incontinence.

Applications And Benefits

  1. Urinary Incontinence: InterStim therapy is particularly effective for individuals experiencing urinary urgency, frequency, or urge incontinence, offering significant improvement in symptoms.
  2. Fecal Incontinence: It also shows promising results in treating fecal incontinence by enhancing control over bowel movements, reducing accidents and improving quality of life.

Patient Experience And Procedure

  1. Evaluation Phase: Before implantation, patients undergo a trial period wherein temporary electrodes are placed near the nerves to assess the potential benefits of InterStim therapy.
  2. Implantation Procedure: If the trial phase is successful, a small device resembling a pacemaker is surgically implanted near the sacral nerves, typically under the skin in the upper buttock area.

Transformative Impact

  1. Improved Quality of Life: InterStim therapy significantly reduces symptoms of urinary and fecal incontinence, allowing individuals to regain control over bodily functions and resume daily activities with confidence.
  2. Minimized Dependency on Medications: For some patients, InterStim therapy reduces reliance on medications for managing incontinence, offering a non-pharmacological alternative.


InterStim stands as a beacon of hope for individuals grappling with the challenges of bladder and bowel control issues. This innovative neuromodulation therapy not only addresses symptoms but also restores a sense of control, dignity, and improved quality of life for those affected by urinary and fecal incontinence.

As InterStim continues to evolve and refine, it embodies the transformative power of medical advancements in providing tangible solutions and renewed hope for individuals seeking to overcome the limitations imposed by bladder and bowel control issues.


What Does An InterStim Do?

InterStim Therapy is an FDA-approved treatment for overactive bladder and urinary retention. With InterStim Therapy, an implantable device sends mild electrical pulses to the sacral nerves to reduce symptoms of bladder control problems, so you can get back to living.

Is InterStim A Major Surgery?

InterStim placement is quickly and safely done at an outpatient surgery center. The procedure itself typically takes between 20-30 minutes to complete, and surgery is minimally invasive.

How Long Does An InterStim Last?

An InterStim battery lasts about five years. If you are continually increasing the power on your InterStim device sooner than five years, you should get your device evaluated to determine if there are issues with the battery or the device. Does InterStim help with pain?
