During lead testing for sacral neuromodulation, what is a key step?

• A. Confirm therapeutic response during testing
• B. Use the device at full amplitude from start
• C. Skip testing and proceed to permanent implantation
• D. Only test in non-sedated patients

Answer: (A)

Verifying that stimulation produces a real symptom improvement during the testing phase is essential in sacral neuromodulation. This step confirms that the lead and stimulation parameters can actually provide relief before committing to a permanent implant. Start with a low, tolerable amplitude and gradually increase while the patient reports changes in symptoms (such as urgency, frequency, or incontinence). This helps identify a therapeutic window and avoids assuming benefit from full-power stimulation, which can cause discomfort or misleading impressions. Testing relies on the patient’s feedback, so it’s typically done with the patient awake; skipping testing or testing only in non-sedated conditions would miss whether meaningful relief is achievable. If a clear therapeutic response is observed within a tolerable range, proceeding to permanent implantation is reasonable. If not, adjustments or reconsideration of candidacy are warranted rather than skipping the testing step.
