Abstract
Aims: In patients with pudendal neuralgia, prior studies have shown efficacy in chronic stimulation with Interstim (R) (Medtronic, Inc.). This feasibility study reports on the initial experience of using a wireless system to power an implanted lead at the pudendal nerve, StimWave (R), to treat pudendal neuralgia.
Methods: Retrospective chart review identified patients with a lead placed at the pudendal nerve for neuralgia and powered wirelessly. Clinical outcomes were assessed at Postoperative visits and phone calls. Administered non-validated followup questionnaire evaluated the Global Response Assessment, percentage of pain improvement, satisfaction with device, and initial and current settings of the device (h/day of stimulation).
Results: Thirteen patients had the StimWave (R) lead placed at the pudendal nerve, 12 (92%) female and 1 ( 7.6%) male. Mean age was 50 years (range: 20-58). Failed prior therapies include medical therapy (100%), pelvic floor physical therapy (92%), pudendal nerve blocks (85%), pelvic floor muscle trigger point injections (69%), neuromodulation (30.7%), or surgeries for urogenital pain (23.1%). After the trial period, 10/13 (76.9%) had >50% improvement in pain with 6/13 (46.1%) reporting 100% pain improvement. Nine underwent permanent lead placement. At last postoperative visit (range, 6-83 days), 5/9 patients reported >50% pain improvement. Seven patients reached for phone calls (22-759 days) reported symptoms to be "markedly improved" (n = 2), "moderately improved" (n = 4), or " slightly improved" (n = 1). At follow up, complications included lead migration (n = 2), broken wire (n = 1), or nonfunctioning antenna (n = 2).
Conclusion: Complex patients with pudendal neuralgia may benefit from pudendal nerve stimulation via StimWave (R).
