Objective: To describe the clinical and electrodiagnostic findings, therapies, and outcomes of patients with pudendal neuralgia.
Study design: A retrospective, descriptive study of 64 patients from March 19 to December 22, 2003.
Results: Clinical findings included pain along nerve distribution (64, 100%), pain aggravated by sitting (62, 97%), pain relieved by standing or lying (57, 89%), and misdiagnosis (53, 83%). Neurophysiologic findings were normal (23, 35%), demyelination (17, 26%), axonal loss (5, 7.5%), and demyelination with axonal loss (21, 32%). Therapies were conservative (64, 100%), nerve injection (38, 59%), neuromodulation (2, 3%), and decompression surgery (10, 15%). Slight or moderate pain improvement with therapies included conservative (64, 100%), nerve injection (12, 31%), neuromodulation (2, 100%), and decompression (6, 60%).
Conclusion: Pudendal neuralgia is poorly recognized and poorly treated. Improvement is gained with conservative therapy. Injections and decompression benefit one half and one third of patients, respectively. Neuromodulation needs further evaluation.
