Sacral Neuromodulation Therapy
Sacral neuromodulation (SNM) is a proven therapy that targets the communication
problem between the brain and the nerves that control the bladder. If
those nerves are not communicating correctly, you may have urgency and
frequency, or leakage of urine associated with urgency.
Sacral neuromodulation stimulates the sacral nerves with mild electrical pulses to modulate the signals with the brain. This treatment is safe and effective and is a viable option for patients who have not had success with behavioral modifications and/or medications for OAB.
This therapy is also indicated for patients with non-obstructive urinary retention (NOUR) and fecal incontinence. More than 13 million adults have both bladder and bowel incontinence.
How Does SNM Therapy Work?
- SNM uses a small neurotransmitter device that can be compared to a pacemaker. To make certain this therapy is right for you, your provider will start you with a basic nerve evaluation that does not require surgery. The evaluation typically lasts 5-7 days.
- The basic nerve evaluation involves the temporary placement of a thin, flexible wire through the skin overlying the sacrum that is then connected to a small external stimulator. The stimulator sends mild electrical impulses through the wire to the nerves that involve bladder function.

Throughout the evaluation phase, your provider will ask you to keep a bladder
diary to record your urinary symptoms and determine if you have experienced
symptom improvement.
You and your provider will review the diary to see if your body responded to the therapy. If so, you may decide to have an internal device placed for long-term therapy during a same-day outpatient procedure.
