Background: Pudendal neuralgia is an intractable pain related to the pudendal nerve. The clinical effect and safety evaluation of pudendal neuralgia were investigated by pulse radiofrequency (PRF) treatment of pudendal nerve. Patients and methods: Eighty patients who were diagnosed with pudendal neuralgia were randomly divided into PRF group (PRF and pudendal nerve block [NB]) and NB group. After surgery, the patients were followed up to evaluate the visual analog scale (VAS) score and the Patient Health Questionnaire score on the postoperative day and at 2 weeks, 1 and 3 months...

This study examined the mechanisms underlying pudendal and tibial neuromodulation of bladder function at the single neuron level in the spinal cord. A microelectrode was inserted into the S2 spinal cord of anesthetized cats to record single neuron activity induced by bladder distention over a range of constant intravesical pressures (10-40 cmH2 O). Pudendal nerve stimulation (PNS) or tibial nerve stimulation (TNS) was applied at 5 Hz frequency and 0.2 ms pulse width and at multiples of the threshold (T) intensities for inducing anal or toe twitches...

BACKGROUND: Penile erection is a complex reflex under spinal control and modulated by the brain. The hemodynamic events under autonomic control and the perineal muscles somatic activity are interconnected during the reflex erection at the spinal level, however if the afferent feedback on the corpus cavernosum pressure during an erection affects the somatic activity (perineal muscles contractions) and vice versa is not known. This study was aimed to test this hypothesis using a rat model...

BACKGROUND: Pudendal neuralgia (PN) is a very painful and often disabling condition in which pudendal nerve blocks play an important role in both the diagnosis and management of PN. Some previous reports have advocated the use of pudendal nerve infiltration (PNI) as a diagnostic test only. OBJECTIVE: We aim to assess the outcomes of patients with typical refractory PN who underwent dual site computed tomography (CT)-guided pudendal nerve infiltration. STUDY DESIGN: A bicentric, retrospective cohort analysis...

BACKGROUND: Catheter-related bladder discomfort (CRBD) to an indwelling urinary catheter is defined as a painful urethral discomfort, resistant to conventional opioid therapy, decreasing the quality of postoperative recovery. According to anatomy, the branches of sacral somatic nerves form the afferent nerves of the urethra and bladder triangle, which deriving from the ventral rami of the second to fourth sacral spinal nerves, innervating the urethral muscles and sphincter of the perineum and pelvic floor; as well as providing sensation to the penis and clitoris in males and females, which including the urethra and bladder triangle...

BACKGROUND: Transperineal pudendal nerve block guided by nerve stimulator is used in pediatric anesthesia as an alternative to caudal analgesia in perineal surgery. The risk of rectal puncture or intravascular injection is inherent to this blinded technique. We described a new technique of transperineal pudendal nerve block, with ultrasound guidance, to improve safety of the technique. AIMS: The first goal of this study was to describe this new technique and to test its feasibility...

The pudendal nerve block (PNB) is widely used for regional anesthesia during obstetric and anorectal procedures, but its role in urologic procedures has not been thoroughly studied. While transvaginal PNB is relatively straightforward, PNB in male patients often requires imaging guidance due to difficulty appreciating anatomic landmarks. We review the PNB and relevant sonoanatomy, and describe its analgesic efficacy in three male patients undergoing urethroplasty for urethral stricture. In this procedure, the patient was placed in lithotomy position, the ischial tuberosity was palpated, and the sacrotuberous ligament and pudendal artery were identified using ultrasound...

This study tested the hypothesis that sacral neuromodulation, i.e., electrical stimulation of afferent axons in sacral spinal root, can block pudendal afferent inhibition of the micturition reflex. In α-chloralose-anesthetized cats, pudendal nerve stimulation (PNS) at 3-5 Hz was used to inhibit bladder reflex activity while the sacral S1 or S2 dorsal root was stimulated at 15-30 Hz to mimic sacral neuromodulation and to block the bladder inhibition induced by PNS. The intensity threshold (T) for PNS or S1/S2 dorsal root stimulation (DRS) to induce muscle twitch of anal sphincter or toe was determined...

Ameet S Nagpal, Erika L Moody
Interventional procedures can be applied for diagnostic evaluation and treatment of the patient with pelvic pain, often once more conservative measures have failed to provide relief. This article reviews interventional management strategies for pelvic pain. We review superior and inferior hypogastric plexus blocks, ganglion impar blocks, transversus abdominis plane blocks, ilioinguinal, iliohypogastric and genitofemoral blocks, pudendal nerve blocks, and selective nerve root blocks. Additionally, we discuss trigger point injections, sacroiliac joint injections, and neuromodulation approaches...

Pelvic neuralgias frequently cause severe pain and may have associated bladder, bowel, or sexual dysfunctions which also impact quality of life. This article explores the etiology, epidemiology, presentation and treatment of common causes of neurogenic pelvic pain, including neuralgia of the border nerves (ilioinguinal, iliohypogastric, and genitofemoral), pudendal neuralgia, clunealgia, sacral radiculopathies caused by Tarlov cysts, and cauda equina syndrome. Treatment of pelvic neuralgia includes conservative measures such as pelvic physical therapy, lifestyle modification, and medications with escalation to more invasive and novel treatments such as nerve blocks, radiofrequency ablation, cryoablation, neuromodulation and neurectomy/neurolysis if conservative treatments are ineffective...

The pudendal nerve entrapment is an entity understudied by diagnosis imaging. Various causes are recognized in relation to difficult labors, rectal, perineal, urological and gynecological surgery, pelvic trauma fracture, bones tumors and compression by tumors or pelvic pseudotumors. Pudendal neuropathy should be clinically suspected, and confirmed by different methods such as electrofisiological testing: evoked potentials, terminal motor latency test and electromyogram, neuronal block and magnetic resonance imaging...

Pudendal neuralgia (PN) is a result of pudendal nerve entrapment or injury, also called "Alcock syndrome." Pain that develops is often chronic, and at times debilitating. If conservative measures fail, invasive treatment modalities can be considered. The goal of this case report is to add to a small body of literature that a pulsed radiofrequency (PRF) ablation can be effectively used to treat PN and to show that high resolution MR neurography imaging can be used to detect pudendal neuropathy. CASE PRESENTATION: We present a case of a 51-year-old woman with 5 years of worsening right groin and vulva pain...

The aim of this study was to develop and evaluate a procedure for equine pudendal nerve block using a peripheral nerve locator. In the first experiment, six ponies were used to determine the relationship between elicited muscle contractions (anal, perineal or both) and nerves serving the perineal region (pudendal, caudorectal and perineal nerves) when methylene blue dye was injected using the electrolocation technique. This experiment showed that the pudendal nerve was approached effectively when both anal and perineal twitch were elicited during electrolocation...
