A Hands‑On Guide to Finding the Pudendal Nerve in Surgery

The pudendal nerve is a key player in pelvic health, but locating it during operations can be tricky. This guide shows surgeons how to find the nerve step by step, using female bodies as models to learn where important blood vessels and other nerves sit. By learning a clear “roadmap,” doctors can avoid cutting vital structures and improve outcomes for patients who need pelvic surgeries.

1. Start at the Outer Edge

• Begin at the outer edge of the pelvis.
• Move inward toward the midline.

2. Identify the Pubic Symphysis

• Look for a small ridge called the pubic symphysis.
• This landmark marks where the nerve will travel.

3. Draw a Guiding Line

• From the pubic symphysis, draw a line that follows the curve of the pelvic bones toward the back.
• This line keeps dissection on track and avoids arteries that supply blood to pelvic organs.

4. Locate the Internal Pudendal Artery

• The artery runs alongside the nerve.
• When seen, the nerve is usually right beside it.
• The artery also signals where to stay clear of other nerves that could be damaged if cut too close.

5. Expose the Pudendal Nerve

• Gently separate tissues to expose the nerve.
• Identify it by its unique texture—slightly thicker than surrounding tissues but still flexible.
• Check for any nearby veins or other nerves that might have been harmed.

6. Protect the Nerve During Surgery

• Remember the path of the artery and the shape of the bone ridge.
• Move around safely to reduce the risk of nerve injury.
• This approach helps patients recover better after pelvic procedures.

By following this structured roadmap, surgeons can navigate the complex anatomy of the pelvis with confidence and precision.
