Background: The objective was to describe clinical findings and outcomes of patients with pudendal neuralgia in relation with the anatomical segment affected.
Methods: Fifty-one consecutive patients with chronic perineal pain (CPP) located in the areas supplied by the pudendal nerve (PN), from January 2011 to June 2012, were analyzed.
Results: The distribution of pain at perineal, dorsal clitoris and inferior anal nerves was 92.2, 31.4 and 25.5% respectively. The duration of pain was longer when the dorsal clitoris nerve (DCN) was affected (p < 0,003). The pain in the pudendal canal was frequently associated with the radiation of pain to the inferior members (p < 0.043).
Conclusion: CPP and radiation of pain to lower limbs suggest a disorder at the second segment of PN. A positive Tinel sign in the third segment indicates a nerve entrapment. In terminal branches, pain was more frequent at the perineal nerve and more persistent at the DCN.
