Summary
Augmented reality (AR) is feasible for sacral nerve stimulation (SNS) lead placement. This technology aids surgeons in accurately placing leads, improving outcomes for patients with incontinence and urinary retention.
Area of Science:
- Medical Technology
- Surgical Innovation
- Neuromodulation
Background:
- Sacral nerve stimulation (SNS) is a treatment for fecal incontinence and urinary retention.
- Accurate lead placement is crucial for effective SNS therapy.
- Current lead placement techniques can be challenging.
Purpose of the Study:
- To assess the feasibility of using augmented reality (AR) during lead placement for SNS.
- To evaluate the practicality and usefulness of AR in guiding needle insertion for SNS procedures.
Main Methods:
- Prospective case series involving 11 patients undergoing SNS.
- Preoperative CT scans and 3D segmentation of anatomy were used for surgical planning.
- Microsoft HoloLens was utilized for intraoperative AR visualization of the planned lead trajectory.
Main Results:
- Mean operative time was 43.8 minutes.
- All patients showed a significant reduction in the Cleveland Clinic Incontinence Score (CCIS) post-procedure (13.3 to 8.5, P < 0.01).
- Surgeons found the AR imaging useful for accurate and easier lead placement.
Conclusions:
- Intraoperative AR imaging is a feasible and practical tool for needle application in SNS.
- AR may enhance the accuracy and efficiency of SNS lead placement.
- The technology shows potential for use in other surgical procedures.
