Sciatic nerve (SN) is the thickest and longest nerve of the body. Deviations from the normal anatomical origin and level of bifurcation of SN have been frequently reported. In the present case, we are presenting a unique scenario of origin of terminal branches of the SN-tibial nerve (TN) and common peroneal nerve (CPN) in the pelvic region itself from divisions arising directly from the lumbosacral plexus. This variation was associated with origin of posterior femoral cutaneous nerve from the superior division of CPN with anomalous communicating branches between pudendal nerve and TN...

IMPORTANCE: Rectovaginal fistula (RVF) is a challenging condition associated with recurrences and significant functional impairment. OBJECTIVES: The internal pudendal artery perforator (IPAP) flap has become a viable option for reconstructing the vagina and perineal regions. This study aims to introduce a modified technique of IPAP flap interposition and evaluate its postoperative outcomes in the treatment of low RVF. STUDY DESIGN: Sixteen patients with RVF who underwent modified IPAP flap interposition between 2016 and 2021 were retrospectively enrolled...

INTRODUCTION AND OBJECTIVE: Pudendal neuralgia is a severely intense, painful, neuropathic condition, involving the dermatome of the pudendal nerve (S2, S3, S4). The diagnosis is complex and usually takes many years to be made. Techniques that use electrical current have been shown to decrease pain and improve quality of life in patients with this condition. The aim of this review was to analyze the existing literature on the effects of electrical current in the treatment of patients with pudendal neuralgia...

OBJECTIVE: To explore how the use of the ProPep® Nerve Monitoring System (ProPep Surgical, Austin, TX, USA) for intraoperative specific sparing of the pudendal nerve fibres influences postoperative functional outcomes after unilateral nerve-sparing (UNS) or non-nerve-sparing (NNS) robot-assisted radical prostatectomy (RARP). PATIENTS AND METHODS: We randomised 100 men undergoing UNS or NNS RARP to ProPep nerve monitoring during RARP (intervention) or standard of care RARP (control)...

OBJECTIVES: To describe sonomorphological changes and appearance of deep endometriosis (DE) affecting the nervous tissue of the sacral plexus (SP). METHODS: This was a retrospective study of symptomatic female patients who underwent radical resection of histologically confirmed DE affecting the SP who had undergone preoperative transvaginal sonography (TVS). Between 2019 and 2023 lesions were described based on the terms and definitions of the International Deep Endometriosis Analysis (IDEA) group...

Hip arthroscopy techniques continue to evolve. Historically, a post has been used as an aid to establish adequate hip joint distraction. However, this technique is associated with potentially devastating postoperative pudendal nerve injury and other urologic and gynecologic complications. In this article, we present our technique for postless hip arthroscopy.

OBJECTIVE: Currently, electrocautery devices have frequently been used in penile surgical procedures. We hypothesized that electrocautery using during penile surgical procedures may harm the taste rosea and the dorsal nerve of the penis or clitoris. METHODS: Eighteen young age male New Zealand rabbits were studied: five in the control (Group I, n =5), five in the penile surgery without using electrocautery (sham group, Group II, n =5), eight in the monopolar cautery (study group, Group III, n =8) groups under general anesthesia...

UNLABELLED: Complications associated with pelvic organ prolapse (POP) surgery using a synthetic non-absorbable mesh are uncommon (<5%) but may be severe and may hugely diminish the quality of life of some women. In drawing up these multidisciplinary clinical practice recommendations, the French National Authority for Health (Haute Autorité de santé, HAS) conducted an exhaustive review of the literature concerning the diagnosis, prevention, and management of complications associated with POP surgery using a synthetic mesh...

Lower urinary tract dysfunction, such as incontinence or urinary retention, is one of the leading consequences of neurological diseases. This significantly impacts the quality of life for those affected, with implications extending not only to humans but also to clinical veterinary care. Having motor and sensory fibers, the pudendal nerve is an optimal candidate for neuromodulation therapies using bidirectional intraneural prostheses, paving the way towards the restoration of a more physiological urination cycle: bladder state can be detected from recorded neural signals, then an electrical current can be injected to the nerve based on the real-time need of the bladder...

PURPOSE: The pudendal nerve is an anatomical structure arising from the ventral branches of the spinal roots S2-S4. Its complex course may be affected by surrounding structures. This may result in irritation or entrapment of the nerve with subsequent clinical symptoms. Aim of this study is to review the anatomy of the pudendal nerve and to provide detailed photographic documentation of the areas with most frequent clinical impact which are essential for surgical approach. METHODS: Major medical databases were searched to identify all anatomical studies investigating pudendal nerve and its variability, and possible clinical outcome of these variants...

Deep gluteal syndrome is a clinical condition in which discomfort may arise due to the pathoanatomy of the subgluteal space. In this study, we conducted an anatomical exploration to categorize the relationship of the piriformis muscle, sciatic nerve, and pudendal nerve to the ischial spine and sacrospinous ligament. Twenty-two cadavers were analyzed. The piriformis muscle, sciatic nerve, and pudendal nerve were exposed either through a transgluteal approach or a gluteal flap. The relationship of the neural structures to the ischial spine, sacrospinous ligament, and ischial bone as they exit the greater sciatic foramen was observed and the exit zones were classified as either: zone A medial to the ischial spine (entirely on sacrospinous ligament), zone B on the ischial spine, and zone C lateral to the ischial spine (entirely on ischial bone)...

Objective: To identify efficacy and safety of pudendal nerve block in tubing through the third posterior sacral foramen for the treatment of pudendal neuralgia (PN). Methods: A retrospective study with 222 PN patients was conducted in the Department of Pain Management of Beijing Tsinghua Changgung Hospital from January 2020 to April 2023. These patients were divided into two groups based on their treatment methods: pudendal nerve block in tubing through the third posterior sacral foramen (observation group, n =101) and ultrasound-guided pudendal nerve block (control group, n =121)...

BACKGROUND: Surgeons vary in their approach to preventing pain post rubber band ligation (RBL) of haemorrhoids, with pudendal nerve blocks (PNB) being one analgesic strategy. No data exists on how commonly PNBs are used in RBL in Australia, and whether use varies by year and patient and hospital characteristics. METHODS: Aggregate data from the National Hospital Morbidity Database was obtained for all admissions for RBL in Australia from 2012 to 2021, with and without a PNB, overall and in relation to sex, age group, hospital remoteness, hospital sector, and year of procedure...

Endometriosis is a common condition that mostly affects people assigned as female at birth. The most common clinical symptom of endometriosis is pain. Although the mechanism for this pain is poorly understood, in some cases, the nerves are directly involved in endometriosis. Endometriosis is a multifocal disease, and the pelvis is the most common location involved. Nerves in the pelvis can become entrapped and involved in endometriosis. Pelvic nerves are visible at pelvic MRI, especially when imaging planes and sequences are tailored for neural evaluation...

PURPOSE: To evaluate online, self-reported pudendal nerve or perineal injuries related to the use of a perineal post during hip arthroscopy. METHODS: Public posts on Reddit and the Health Organization for Pudendal Education were searched to identify anonymous individuals reporting symptoms of pudendal nerve or perineal injury following hip arthroscopy. Included posts were by any individual with a self-reported history of hip arthroscopy who developed symptoms of pudendal nerve injury or damage to the perineal soft tissues...

Chronic penile pain is a complex clinical entity with limited diagnostic criteria and treatment options. Due to limited reporting of these cases, there are no clear clinical treatments and indications for when these patients present to the clinic. This case report will highlight the diagnostic challenges encountered and the subsequent management strategies employed while working up a patient with penile pain. We present a 37-year-old male with a six-year history of debilitating penile pain, urinary frequency, and urgency that is exacerbated by sexual arousal and touch...

PURPOSE: Erectile dysfunction (ED) is a common side effect after prostate cancer stereotactic body radiotherapy (SBRT). We aimed to assess the correlation between the dose to the penile bulb (PB), internal pudendal arteries (IPA), and crura with the development of ED after ultra-hypofractionation as part of a phase II clinical trial of urethra-sparing prostate SBRT. MATERIAL AND METHODS: Among the 170 patients with localized prostate cancer from 9 centers included in the trial, 90 men with CTCAE v4...

BACKGROUND: Pudendal nerve block (PNB) is a commonly used anesthesia method that has been widely used in postoperative analgesia for hemorrhoids in recent years. Therefore, we conducted a systematic review and meta-analysis of double-blind randomized controlled trials (RCTs) to analyze the effectiveness of PNB in postoperative analgesia for hemorrhoids. METHODS: Relevant data and studies published from inception until August 14, 2023, were retrieved from PubMed, Embase, and Web of Science to evaluate the beneficial effects of PNB for analgesia following hemorrhoidectomy...

Lower urinary tract dysfunction (LUTD) encompasses a range of debilitating conditions that affect both sexes and different age groups. Understanding the underlying neurobiological mechanisms contributing to LUTD has emerged as a critical avenue for the development of targeted therapeutic strategies. Brain-derived neurotrophic factor (BDNF), a prominent member of the neurotrophin family, has attracted attention due to its multiple roles in neural development, plasticity, and maintenance. This review examines the intricate interplay between neurobiological factors and LUTD, focusing on the central involvement of BDNF...

An artificial sphincter implanted in the bulbous urethra to treat severe postprostatectomy urinary incontinence is effective, but embedding-associated complications can occur. We assessed the feasibility, efficacy, and safety of urethral graciloplasty cross-innervated by the pudendal nerve. A simulation surgery on three male fresh cadavers was performed. Both ends of the gracilis muscle were isolated only on its vascular pedicle with proximal end of the obturator nerve severed and transferred to the perineum...
