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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
