I am about to start the first stage of the Interstim implant. When talking to my urologist he mentioned that there is a new way to implant the external device, so that it is more accurate. I didn't understand how this is more effective. Could you please explain this to me? Thank you.

I am unsure of what is meant by “a new way to implant the external device, so that it is more accurate”.
Perhaps he means the method described by Dr’s Chai and Mamo (see below)?
Please ask you urologist for the details that you require.


Modified techniques of S3 foramen localization and lead implantation in S3 neuromodulation.

INTRODUCTION: We describe a reproducible and less invasive surgical approach to sacral neuromodulation (InterStim Therapy) in the treatment of voiding dysfunction. Twenty patients underwent modified lead implantation (mean operative time 45 minutes) without any difficulties or complications, with a mean follow-up of 8 months (range 1 to 14).Technical Considerations. The highlights of these modifications include (a) fluoroscopy to localize the S3 foramen; (b) paramedian incision; (c) use of a cutoff S3 finder needle and a 14-gauge Angiocath to direct permanent lead into the S3 foramen without dissection; (d) use of lateral fluoroscopy to determine the depth of the Angiocath insertion; and (e) anchoring the lead to the lumbodorsal fascia (superficial to the sacral periosteum) using a moveable lead anchor system. These modifications simplify and minimize the invasiveness of this therapy without compromising the efficacy. CONCLUSIONS: Because of the simplicity of these modifications, we are currently using an implanted lead, rather than the temporary percutaneous lead, to assess patients' clinical response before implanting a pulse generator.
