OBJECTIVES: To examine the diagnostic value of pudendal somatosensory evoked potentials (SEP) in pudendal nerve entrapment neuropaty (PNE) by stimulating the two sides separately after provocation by a standard sitting position. Routine pudendal SEPs performed in the supine position with bilateral simultaneous stimulation may fail to show the abnormality because the complaints of PNE appear or worsen in the sitting position. METHODS: Forty-nine patients with PNE and 16 controls were included...

Pudendal neuralgia is being increasingly recognized as a cause of chronic pelvic pain, which may be related to nerve injury or entrapment. Due to its complex anatomy and branching patterns, the pudendal nerve abnormalities are challenging to illustrate. High resolution 3 T magnetic resonance neurography is a promising technique for the evaluation of peripheral neuropathies. In this article, the authors discuss the normal pudendal nerve anatomy and its variations, technical considerations of pudendal nerve imaging, and highlight the normal and abnormal appearances of the pudendal nerve and its branches with illustrative case examples...

Chronic pelvic pain is a disabling condition that affects a large number of men and women. It may occur after a known inciting event, or it could be idiopathic. A common cause of pelvic pain syndrome is neuropathy of the pelvic nerves, including the femoral and genitofemoral nerves, ilioinguinal and iliohypogastric nerves, pudendal nerve, obturator nerve, lateral and posterior femoral cutaneous nerves, inferior cluneal nerves, inferior rectal nerve, sciatic nerve, superior gluteal nerve, and the spinal nerve roots...

A variety of neuromodulation approaches have been described for the management of pelvic neuropathies, including interstitial cystitis, pudendal neuralgia and persistent genital arousal disorder. The benefits of a combined sacral and pudendal nerve neuromodulator has yet to be explored for these patients. In this report, we describe the case of a 35-year-old woman with a complex pelvic neuropathy resulting in urinary, sexual and gastro-intestinal dysfunction. She presented with an established diagnosis of interstitial cystitis; however, she also fulfilled diagnostic criteria for pudendal neuralgia and persistent genital arousal disorder...

BACKGROUND: Pudendal neuropathy is a tunnel syndrome characterized by pelvic pain and may include bowel, bladder, or sexual dysfunction or a combination of these. One treatment method, pudendal nerve perineural injections (PNPIs), uses infiltration of bupivacaine and corticosteroid around the nerve to provide symptom relief. Bupivacaine also anesthetizes the skin in the receptive field of the nerve that is injected. Bupivacaine offers rapid pain relief for several hours while corticosteroid provides delayed pain control often lasting 3 to 5 weeks...

COMPARATIVE STUDY
Maxime M van Meegdenburg, Erik Heineman, Paul M A Broens
BACKGROUND: Conscious external anal sphincter contraction is mediated by the pudendal nerve. Pudendal neuropathy is, therefore, believed to result in fecal incontinence. Until urge sensation is experienced, fecal continence is maintained by unconscious external anal sphincter contraction, which is regulated by the anal-external sphincter continence reflex. The innervation of unconscious contraction is yet unknown. OBJECTIVE: We aimed to determine whether unconscious contraction is mediated by the pudendal nerve and whether age influences unconscious contraction...

OBJECTIVE: Fecal incontinence (FI) occurs in up to 20% of diabetes mellitus (DM) patients. Rectoanal inhibitory reflex (RAIR) is an enteric anorectal reflex that reflects the integrity of mechanisms in the physiology of FI. We aimed to investigate whether diabetic patients with FI, not constipation, had prolongation of RAIR and altered gut-specific autonomic tone. METHODS: In this prospective case-matched study 31 type I DM (19 FI and 12 constipation) and 42 type II DM (26 FI and 16 constipation)...

INTRODUCTION AND OBJECTIVE: The urinary incontinence after radical prostatectomy is secondary to neuropathy with various degrees from neurapraxia to neurotmesis. We propose to apply therapeutic and rehabilitative models appropriate to the diagnosis and to evaluate the results. MATERIALS AND METHODS: We examined 79 homogeneous patients with urinary incontinence after radical prostatectomy. After having defined the diagnosis by a urodynamic examination, the study of pudendal nerve somatosensory-evoked potentials (SEPs) and perineal electromyography (EMG), patients were divided into four groups (A; B; C; D) and submitted to different clinical drug protocols and rehabilitation...

Pudendal nerve entrapment (PNE) is an uncommon cause of chronic pain. Pudendal nerve entrapment typically occurs when the pudendal nerve is fused to nearby anatomical structures or trapped between the sacrotuberous and sacrospinalis ligaments. Pudendal nerve entrapment can be caused by excessive bicycling, pregnancy, anatomic abnormalities, scarring due to surgery, or as a sequela of radiation therapy. Radiation-induced peripheral neuropathy is usually chronic, progressive, and often irreversible. Radiation-induced pudendal neuropathy is much less common than the more familiar brachial plexopathy secondary to radiation treatment for breast cancer...

INTRODUCTION: Pudendal nerve neurapraxia is a classic complication after traction on the fracture table. Diagnosis, however, is difficult and often overlooked, especially after arthroscopy in traction on fracture table; incidence is therefore not known exactly. HYPOTHESIS: The study hypothesis was that incidence of pudendal nerve neuropathy exceeds 1% after hip arthroscopy. MATERIALS AND METHODS: Results for 150 patients (79 female, 71 male) undergoing hip arthroscopy between 2000 and 2010 were analyzed retrospectively...
