Objective: To define the place of pudendal nerve surgery in pudendal nerve entrapment syndromes.
Materials and methods: Description of the various surgical techniques and published results.
Results: The original surgical technique, which remains the reference technique, consists of performing surgical release of the pudendal nerve from the infrapiriformis foramen to Alcock's canal via a transgluteal approach. This surgical procedure is safe and gives encouraging results validated by a prospective, randomized protocol: 66 to 80% of patients are improved. Other transvaginal or transperineal approaches have also been proposed.
Conclusion: Pudendal nerve surgery is a reasonable treatment option when all other treatments have failed. However, the various techniques proposed and their respective criticisms must be carefully evaluated.
