[Treatments of perineal neuralgia caused by involvement of the pudendal nerve].

We report 170 cases of perineal neuralgia due to pudendal nerve compression within Alcock canal or by ischiatic spine. 117 women and 53 men were investigated. Mean age was 60.3 years and the follow-up one year. Infiltrations of the pudendal nerve in the ischio-rectal fossa (pudendal canal or Alcock canal) with corticoids under CT-scan guidance, were successful immediately in only 1/3 of the cases. Infiltrations of the nerve near by ischiatic spine (radioscopic guidance) were successful in 57 p. 100, but only in 15 p. 100 of the cas after one year. Surgical treatment (performed in 27 cases) was good (8 or excellent (9). For all treatments, the results are good in 65 p. 100 of the cases. Perineal neurophysiologic examinations are useful to confirm pudendal nerve lesion and propose specific medical and/or surgical treatment.
