Sacral Nerve Stimulation: A New Hope for Pelvic Pain Relief?
"Exploring the anterograde sacral hiatus approach to alleviate chronic pelvic pain when traditional methods fall short."
Chronic pain can be a relentless adversary, significantly diminishing the quality of life for millions. Among the various types of chronic pain, pelvic pain stands out due to its complexity and the challenges it presents in diagnosis and treatment. Spinal cord stimulation (SCS) has emerged as a valuable tool in managing various chronic pain conditions since 1967, offering hope when other treatments prove ineffective.
Sacral nerve stimulation, a specialized form of SCS, has been utilized to address conditions like peroneal pain and irritable bowel syndrome through a retrograde approach. However, anatomical obstacles or prior surgeries can sometimes impede the successful advancement of leads using this method. In such cases, an alternative approach becomes necessary to provide effective pain relief.
This article delves into a promising technique: anterograde sacral nerve stimulation through the sacral hiatus. This method offers a new pathway to access the sacral nerves, potentially providing relief for individuals with intractable chronic pelvic pain when traditional approaches are not feasible. We will explore the procedure, its benefits, and its role in the evolving landscape of pain management.
The Anterograde Sacral Hiatus Approach: A Step-by-Step Guide

The anterograde sacral nerve stimulation technique involves accessing the sacral nerves through the sacral hiatus, an opening at the lower end of the sacrum. This approach is performed with the patient in a prone position, allowing the physician to visualize the area using fluoroscopy, a type of real-time X-ray.
- Needle Insertion: A Tuohy needle is carefully inserted into the sacral hiatus under fluoroscopic guidance.
- Lead Placement: Percutaneous leads are then passed through the needle and advanced into the posterior sacral epidural space. The leads are positioned to target specific sacral nerve roots responsible for the patient's pain.
- Lead Anchoring: To secure the leads and prevent migration, a small incision is made, and the leads are anchored to the surrounding tissues.
- IPG Implantation: A rechargeable implantable pulse generator (IPG) is placed in a subcutaneous pocket, typically in the upper buttock area. The leads are then connected to the IPG, which delivers controlled electrical pulses to the sacral nerves.
A Promising Alternative for Intractable Pelvic Pain
While the anterograde sacral nerve stimulation through the sacral hiatus presents some challenges, it offers a valuable alternative for patients with intractable chronic pelvic pain when traditional methods are not viable. Further research and refinement of this technique may expand its application and improve outcomes for individuals seeking relief from debilitating pelvic pain.
