The patient reported significant pain relief after her block during the local anesthetic phase of the injection. We repeated a left pudendal nerve block with fluoroscopic guidance and nerve stimulation for localization to assess candidacy for peripheral nerve stimulation. Given these findings, the patient chose to pursue pudendal nerve entrapment release surgery but continued to report the same pain after this operation. Magnetic resonance (MR) neurography of the lumbosacral plexus identified signal abnormality in the course of the left pudendal nerve along the ischial spine and obturator internus muscle. Pain medications included duloxetine and opioids (methadone and oxycodone). Each intervention provided less than two weeks of pain relief. Prior pain treatments included pudendal nerve blocks, obturator nerve block, epidural steroid injections, and obturator internus trigger point injections with onabotulinumtoxin-A (Botox).

CaseĪ 76-year-old female presented with >25 years of chronic pelvic pain including increasing vaginal vault pain and rectal pain. We briefly discuss the patient’s pain management and their postimplant course. In this review, we present a case of a patient with refractory pudendal neuralgia who elected to pursue peripheral nerve stimulator implant.

Therefore, alternative treatment modalities are still required. Although sacral neuromodulation has most commonly been described in the management of PN, between 10% and 25% of patients do not respond. Recent studies indicate that pudendal nerve stimulation may be effective in decreasing symptom burden in patients with refractory pain. A variety of neuromodulation techniques have been trialed in the management of refractory cases of pudendal neuropathy, ranging from spinal cord stimulation to neuromodulation of the dorsal root ganglia, sacral nerve roots, conus medullaris, and the pudendal nerve itself. Pain management includes behavioral modification, pelvic floor physiotherapy, medications, nerve blocks, and surgical decompression.

The five essential diagnostic criteria are 1) pain in the anatomical territory of the pudendal nerve, 2) pain worsened by sitting, 3) the patient is not woken at night by the pain, 4) no objective sensory loss on clinical examination, and 5) positive anesthetic pudendal nerve block. published the Nantes criteria, which have been subsequently suggested to be helpful in standardizing the diagnosis of pudendal neuropathy. It is a clinical diagnosis that involves pain in the dermatomal area of the pudendal nerve and can present with associated urinary frequency and urgency, symptoms of painful bladder syndrome, perineal pain, and dyspareunia. The pudendal nerve is a mixed somatic and autonomic nerve that originates from the S2–S4 nerve roots innervating the pelvic floor muscles, external urethral and anal sphincters, and pelvic organs. Pudendal neuralgia can have devastating effects on a patient’s quality of life and severely limit activities of daily living, and it is most common after childbirth, pelvic trauma, and surgical injury. Pudendal neuralgia (PN) is a chronic, disabling form of genital pain caused by inflammation, compression, or entrapment of the pudendal nerve and is estimated to affect 4% of patients with chronic pain.
