RESUMO

INTRODUCTION: Premature ejaculation (PE) affects 8% to 30% of adult men worldwide. Recently, the incidence of PE is on the rise. A series of prior studies suggested that the incidence of PE is related to various biological factors as low testosterone, low serum vitamin D, diabetes, lower urinary tract symptoms, and other psychological factors. At present, the major treatments include selective serotonin reuptake inhibitors antidepressants (dapoxetine, paroxetine), topical anesthetics, phosphodiesterase-5 inhibitor, circumcision, and selective dorsal neurotomy (SDN). The previous study found that SDN is effective for PE. METHODS AND ANALYSIS: The electronic databases of MEDLINE, PubMed, Web of Science, EMBASE, Cochrane Library, Clinicaltrials. org, China National Knowledge Infrastructure Database (CNKI), Wan fang Database, China Biology Medicine Database (CBM), VIP Science Technology Periodical Database, Chinese Clinical Trial Registry will be retrieved. All the randomized controlled trials of selective dorsal penile neurotomy for patients with PE will be included. The outcome includes intravaginal ejaculation latency time and Chinese Index of Sexual Function for Premature Ejaculation-5. We will conduct this study strictly according to the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS: The present study is a protocol for systematic review and meta-analysis without results, and data analysis will be carried out after the protocol. We will share our findings on June 30th of 2021. CONCLUSION: SDN can effectively prolong IELT, but its efficacy has not been assessed scientifically and systematically. To address this limitation, this study will inspect the efficacy and safety of the SDN treatment in patients with PE. ETHICS AND DISSEMINATION: Formal ethical approval is not required in this protocol. We will collect and analyze data based on published studies, and since there are no patients involved in this study, individual privacy will not be under concerns. The results of this review will be disseminated to peer-reviewed journals or submit to related conferences. PROTOCOL REGISTRATION NUMBER: INPLASY202070084.

RESUMO

BACKGROUND: Pudendal and cluneal nerve entrapment can cause a neuropathic pain syndrome in the sensitive areas innervated by these nerves. Recently, a new endoscopic minimal invasive approach for pudendal and inferior cluneal nerve neurolysis has been published in a cadaver study. The aim of our study was to describe the feasibility of this new approach and to evaluate the clinical outcome. METHODS: Fifteen patients underwent the ENTRAMI technique. The Numeric Pain Rating Scale (NPRS) and Patient Global Impression of Change (PGIC) were recorded at baseline and at 3 and 6 months after surgery. RESULT: The average duration of intervention (skin to skin) was 139 min (range 50-270 min) for bilateral pudendal neurolysis and/or cluneal neurolysis and 113 min (range 100-130 min) for unilateral pudendal and/or cluneal neurolysis. No perioperative blood loss occurred. At 3 months, 50% of patients declared a more than 30% improvement of their PGIC, increasing to 57% at 6 months; 31% reported more than 90% improvement of PGIC at 6 months. Overall reduction of the average maximal NPRS score was from 9 (range 7-10) to 6 at 3 months (range 0-10; p value < 0.05) and to 5 at 6 months (range 0-10; p value < 0.05). There were no postoperative complications. CONCLUSIONS: The ENTRAMI technique is feasibly in patients suffering from pudendal and/or cluneal neuralgia and preliminary results are promising. CLINICAL TRIAL NUMBER: NCT03883178.

RESUMO

Patients suffer bilateral sacral plexus injuries experience severe problems with incontinence. We performed a cadaveric study to explore the anatomical feasibility of transferring ipsilateral S2 nerve root combined with a sural nerve graft to pudendal nerve for restoration of external anal and urethral sphincter function. The sacral nerve roots and pudendal nerve roots on the right side were exposed in 10 cadavers. The length from S2 nerve root origin to pudendal nerve at inferior border of piriformis was measured. The sural nerve was used as nerve graft. The diameters and nerve cross-sectional areas of S2 nerve root, pudendal nerve and sural nerve were measured and calculated, so as the number of myelinated axons of three nerves on each cadaver specimen. The length from S2 nerve root to pudendal nerve was 10.69 ± 1.67 cm. The cross-sectional areas of the three nerves were 8.57 ± 3.03 mm2 for S2, 7.02 ± 2.04 mm2 for pudendal nerve and 6.33 ± 1.61 mm2 for sural nerve. The pudendal nerve contained approximately the same number of axons (5708 ± 1143) as the sural nerve (5607 ± 1305), which was a bit less than that of the S2 nerve root (6005 ± 1479). The S2 nerve root in combination with a sural nerve graft is surgically feasible to transfer to the pudendal nerve for return of external urethral and anal sphincter function, and may be suitable for clinical application in patients suffering from incontinence following sacral plexus injuries.

RESUMO

OBJECTIVE: Intraoperative neurophysiological monitoring (INM) allows obtaining real-time information on the functional integrity of nervous system structures. The objective of this article is to present the role of clinical neurophysiology in Urology in the identification and preservation, on the one hand, of the prostate neurovascular bundles in radical prostatectomy (RP), and of the pudendal nerve in the release of this in Pudendal Nerve Entrapment Syndrome (PNS). METHODS: A bipolar laparoscopic probe was used for intraoperative stimulation for both the identification in PNS and neurovascular bundles in RP, obtaining response at the external anal sphincter in the first one; and intracavernous pressure in the second through needle electrodes. RESULTS: Preservation of the periprostatic neurovascular bundles allows to increase rates of sexual potency and urinary continence after surgery. However, it has been shown that the innervation of the corpora cavernosa and the urinary sphincter has a variable disposition. Intraoperative neurostimulation allows the most precise identification and dissection of the vascular and nervous structures that surround the prostate. In the diagnosis of PNS, the neurophysiological study allows to rule out pathology at other levels, such as, primary muscular pathology of the anal sphincter. There are no pathognomonic neurophysiological findings of PNS. In addition, it allows the identification of the nerve during the laparoscopic release of the nerve at the entrance of the Alcock channel, as well as the evaluation of its functional integrity after the end of the dissection. CONCLUSIONS: The INM is a fundamental tool to allow an improved identification of nerve structures during RP and PNS in order to preserve them. It also helps with the diagnosis of PNS.

RESUMO

Objetivo: La monitorización neurofisiológica intraoperatoria (MNI) permite obtener información en tiempo real sobre la integridad funcional de las estructuras del sistema nervioso. El objetivo de este trabajo exponer el papel de neurofisiología clínica en Urología en la identificación y preservación, por un lado, de los haces neurovasculares prostáticos en la prostatectomía radical (PR), y del nervio pudendo en la liberación de este en el Síndrome de Atrapamiento del Nervio Pudendo (SANP). Métodos: Se empleó una sonda bipolar laparoscópica para la estimulación intraoperatoria tanto para la identificación en SANP como de haces neurovasculares en PR obteniéndose respuesta a nivel del esfínter anal en la primera y presión intracavernosa en la segunda por medio de electrodos de aguja. Resultados: La presentación de los haces neurovasculares periprostáticos permite aumentar las tasas de potencia sexual y continencia urinaria. Si bien, posteriormente, se evidenció que la inervación de los cuerpos cavernosos y el esfínter urinario tiene disposición variable. La neuroestimulación intraoperatoria permite la identificación y disección más precisa de las estructuras vasculonerviosas que circundan la próstata. En el diagnóstico del SANP, el estudio neurofisiológico permite descartar patología a otros niveles, como por ejemplo patología primaria muscular del esfínter anal; así como, valorar las ramas del nervio pudendo. No existen hallazgos neurofisiológicos patognomónicos del SANP. Además, permite la identificación del nervio durante la liberación laparoscópica del nervio a la entrada del canal de Alcock, así como la evaluación de su integridad funcional tras finalizar la disección. Conclusiones: La MNI es una herramienta fundamental para permitir una mejora en la identificación de estructuras nerviosas durante PR y SANP para poder preservarlas. Así mismo, ayuda con el diagnóstico de SANP

RESUMO

AIM: To evaluate initial experience with computed tomography (CT)-guided pulsed radiofrequency ablation (pRFA) of the pudendal nerve in cases of recalcitrant neuropathic pelvic pain. Endpoints include technical feasibility, safety, and efficacy of therapy. MATERIALS AND METHODS: Ten patients who underwent pRFA ablation for neuropathic pudendal nerve pain during the trial period were followed for response to treatment for 6 months. Each patient was treated with pRFA under CT-guidance with concurrent perineural injection of anaesthetic and/or corticosteroid. Pain scores were then measured using a numeric rating scale at fixed intervals up to 6 months. RESULTS: All procedures were considered technically successful with no immediate complications. pRFA demonstrated improved duration of pain improvement compared to the most recent perineural injection (p=0.0195), but not compared to the initial injection (p=0.64). Reported pain scores were lower with pRFA than with both the first and most recent injection but this did not reach statistical significance (p=0.1094 and p=0.7539, respectively). CONCLUSION: Overall, pRFA of the pudendal nerve using CT-guidance can be a safe and effective therapy. This technique provides direct visualisation of the nerve to maximise safety and efficacy while offering a novel form of therapy for patients with chronic, recalcitrant pelvic pain.

RESUMO

INTRODUCTION: Phalloplasty attempts to achieve a functional and aesthetic phallus. Sensation is a key component for sexual pleasure. Sensation is also important for protection in the setting of penile implant insertion. Little data are available on genital sensibility outcomes after phalloplasty, and there are no standardized approaches for assessment of either sensibility or erogenous perception. METHODS: A literature search of PubMed, Google Scholar, and MEDLINE databases was conducted with terms related to genital sensibility after phalloplasty. Data on patient demographics, nerves used for coaptation, and measurements of genital sensibility were collected. Pooled event rates were determined for recovered glans sensibility and recovered erogenous sensation using a Freeman-Tukey arcsine transformation. RESULTS: A total of 341 articles were identified of which 26 met the inclusion criteria for final analysis. The dorsal cutaneous branch of the pudendal nerve and ilioinguinal were the most common donor nerves. The lateral and medial antebrachial cutaneous and lateral femoral cutaneous were the most common recipient nerves. Pooled event rates suggest that some recovered glans sensibility occurs in more than 70% of cismale patients and in more than 90% of transmale patients. Recovered "erogenous" sensation occurs in more than 75% of cismale patients and more than 95% of transmale patients. In cismale patients, outcomes of recovered glans sensibility and erogenous sensation may be better for upper extremity recipient nerves than lower extremity recipient nerves. CONCLUSIONS: Based on the limited data in current literature on genital sensibility after phalloplasty, it is difficult to draw evidence-based conclusions. Yet data support improved outcomes with innervation. A validated outcome measure of "erogenous sensation" and a standardized approach to measuring cutaneous sensibility are required.

RESUMO

STUDY OBJECTIVE: To demonstrate the laparoscopic approach to malformed branches of the vessels entrapping the nerves of the sacral plexus. DESIGN: A step-by-step explanation of the surgery using video (educative video) (Canadian Task force classification II). The university's Ethics Committee ruled that approval was not required for this video. SETTING: Kocaeli Derince Education and Research Hospital, Kocaeli, Turkey. PATIENT: A 26-year-old patient who had failed medical therapy and presented with complaints of numbness and burning pain on the right side of her vagina and pain radiating to her lower limbs for a period of approximately 36 months. INTERVENTION: The peritoneum was incised along the external iliac vessels, and these vessels were separated from the iliopsoas muscle on the right side of the pelvis. The laparoscopic decompression of intrapelvic vascular entrapment was performed at 3 sites: the lumbosacral trunk, sciatic nerve, and pudendal nerve. The aberrant dilated veins were gently dissected from nerves, and then coagulated and cut with the LigaSure sealing device (Medtronic, Minneapolis, Minn). MEASUREMENTS AND MAIN RESULTS: The operation was completed successfully with no complications, and the patient was discharged from the hospital 24 hours after the operation. At a 6-month follow-up, she reported complete resolution of dyspareunia and sciatica (visual analog scale score 1 of 10). CONCLUSION: A less well-known cause of chronic pelvic pain is compression of the sacral plexus by dilated or malformed branches of the internal iliac vessels. Laparoscopic management of vascular entrapment of the sacral plexus has been described by Possover et al [1,2] and Lemos et al [3]. This procedure appears to be feasible and effective, but requires significant experience and familiarity with laparoscopy techniques and pelvic nerve anatomy.

Material y métodos: Se describe paso a paso la técnica de neurólisis laparoscópica asistida por robot del NP izquierdo realizada con monitorización neurofisiológica intraoperatoria en una paciente de 60 años de edad a quien se diagnosticó SAP izquierdo. Resultados: El procedimiento se realizó de forma satisfactoria sin complicaciones. Tras 24 h se procedió al alta hospitalaria. Se objetivó una reducción del dolor del 50% medida mediante Escala Visual Analógica a las 2 semanas del procedimiento, mantenida tras 10 semanas de la neurólisis. Conclusiones: La neurólisis robótica del NP constituye una vía de abordaje factible y segura, permitiendo una mejor visualización y precisión en la disección del NP. La monitorización neurofisiológica intraoperatoria es útil para la localización del NP y para la detección de cambios intraoperatorios tras la liberación del nervio


Introduction: Pudendal nerve entrapment syndrome (PNE) is characterised by the presence of neuropathic pain in the pudendal nerve (PN) territory, associated or not with urinary, defecatory and sexual disorders. Surgical PN decompression is an effective and safe alternative for cases when conservative treatment fails. The aim of this study is to describe the first robot-assisted pudendal neurolysis procedure performed in our country. Material and methods: We describe step by step the technique of robot-assisted laparoscopic neurolysis of the left PN performed with intraoperative neurophysiological monitoring on a 60-year-old patient diagnosed with left PNE. Results: The procedure was performed satisfactorily without complications. After 24h, the patient was discharged from the hospital. We observed a 50% reduction in pain measured using the visual analogue scale 2 weeks after the procedure, which remained after 10 weeks of the neurolysis. Conclusions: Robot-assisted neurolysis of the PN constitutes a feasible and safe approach, enabling better visualisation and accuracy in the dissection of the PN. Intraoperative neurophysiological monitoring is useful for locating the PN and for detecting intraoperative changes after the release of the nerve

RESUMO

BACKGROUND: Pudendal nerve entrapment can produce a pudendal syndrome comprising perineodynia together with urinary, sexual, and anorectal symptoms. This syndrome can be treated surgically by the transperineal approach. By using an endoscope during the procedure ("operative pudendoscopy"), the surgeon has close-up visual control of each decompression steps, demonstrates the different levels of entrapment, and cuts the sacrospinous ligament under visual control. The aim of this study was to describe the technical details of this new technique and its outcome in the treatment of the pudendal syndrome. METHODS: A series of 113 patients with severe pudendal syndrome underwent operative pudendoscopy. A complete history, pain visual analog scale (VAS) for perineodynia, and four scores evaluating the main symptoms (ICIQ-SF, NHI-CPSI, St Mark's, and Wexner) were obtained before and at least 24 months after surgery. The three clinical signs of pudendal syndrome (abnormal pinprick sensitivity, painful skin rolling test, and painful pudendal nerve) and perineal descent were analyzed before and after surgery in 91 patients. RESULTS: The mean operating time per side was 50.3 ± 15.2 min and the average hospital stay was 2.1 ± 0.4 days. Perineodynia VAS dropped from 7.2 ± 1.4 to 4.5 ± 2.9 after surgery (p < 0.0001) and the symptoms scores significantly improved. Frequency of sexual arousal syndrome, dyspareunia, and cystalgia was also significantly reduced. Pathological perineal descent (≥ 1.5 cm measured with a Perineocaliper®) observed in 13 patients was reduced from 1.81 to 0.77 cm after surgery (p < 0.0001). The only significant complication was severe hemorrhage in one patient induced by an inferior gluteal vessel laceration and successfully treated by arterial embolization. CONCLUSIONS: A complete pudendal nerve decompression, from the distal branches to the sacral foramina, safely performed under visual control by using operative pudendoscopy markedly improves clinical signs and symptoms of the pudendal syndrome.

RESUMO

OBJECTIVE: The objective is to report the outcome of an anterior surgical approach to treat neuroma of the perineal branch of the pudendal nerve (PBPN). PATIENTS AND METHODS: An IRB-approved prospective study enrolled 14 consecutive male patients from 2011 through 2015 who had symptoms of perineal/scrotal pain. Each patient had a successful, diagnostic, pudendal nerve block. The surgical procedure was resection of the PBPN and implantation of the nerve into the obturator internus muscle. Mean age at surgery was 50 ± 15 years. Median duration of pain symptoms was 5.5 years (range 1.2-42.9 years). Mechanisms of injury was exercise (6/14), prostatectomy (4/14), and falls (4/14). Outcomes were the Male Pudendal Pain Functional Questionnaire (MQ), and the Numeric Pain Rating Scale (NPRS). RESULTS: The mean postoperative follow-up was 26 ± 14 months. The MQ demonstrated that after surgery, patients overall had significantly less disability due to pudendal pain (P < .03). The NPRS revealed that pain significantly improved (P < .004). CONCLUSIONS: Resection of the PBPN and implantation of this nerve into the obturator internus muscle significantly relieved men's pelvic pain disability.

RESUMO

AIM: To describe a new minimal invasive approach of the gluteal region which will permit to perform neurolysis of the pudendal and cluneal nerves in case of perineal neuralgia due to an entrapment of these nerve trunks. METHOD: Ten transgluteal approaches were performed on five cadavers. Relevant anatomic structures were dissected and further described. Neurolysis of the pudendal nerve or cluneal nerves were performed. Landmarks for secure intraoperative navigation were indicated. RESULTS: The first operative trocar for the camera was inserted with regards to the iliac crest in the deep gluteal space. With the aid of pneumodissection, the infragluteal plane was dissected. The piriformis muscle was identified as well as the sciatic and the posterior femoral cutaneous nerve. Consequently, the sciatic tuberosity was visualized together with the cluneal nerves. Hereafter, the second trocar was introduced caudal to the first one and placed on an horizontal line passing at the level of the coccyx, allowing access to the ischial spine and the visualization of the pudendal nerve and vessels. A third 5 mm trocar was then inserted medial from the first one, permitting to dissect and transsect the sacrospinous ligament. The pudendal nerve was subsequently transposed and followed on its course in the pudendal channel. CONCLUSIONS: A reliable exploration of the gluteal region including identification of the sciatic, pudendal, and posterior femoral cutaneous nerves is feasible using a minimal invasive transgluteal procedure. Consequently, the transposition of the pudendal nerve and the liberation of the cluneal nerves can be performed.

RESUMO

OBJECTIVE: To simulate sacrospinous ligament fixation on cadaveric specimens, describe the surrounding retroperitoneal anatomy, and estimate the risk to nerves and arteries for the purposes of optimizing safe suture placement. METHODS: Sacrospinous ligament fixation was performed on eight fresh-tissue female cadavers using a Capio ligature capture device. Distances from placed sutures to the following structures were measured: ischial spine; fourth sacral root; pudendal nerve; the nerve to coccygeus muscle; the nerve to levator ani muscle; inferior gluteal artery; and internal pudendal artery. Periligamentous anatomy was examined in an additional 17 embalmed cadaver dissections. RESULTS: Sacrospinous ligament length was not seen to differ significantly between sides. The fourth sacral spinal nerve was seen most commonly associated with the medial third of the ligament, whereas the pudendal nerve and the nerves to coccygeus and levator ani muscles were associated with the lateral third. The inferior gluteal artery was seen leaving the greater sciatic foramen a median 15.8 mm (range 1.8-48.0, CI 14.9-22.3) above the ligament, whereas the internal pudendal artery exited just above the ischial spine. The two sets of sutures were placed 20.5 mm (range 9.2-34.4, CI 19.7-24.7) and 24.8 mm (range 12.4-46.2, CI 24.0-30.0) medial to the ischial spine, respectively. No structures were directly damaged by placed sutures. The nerves to coccygeus and levator ani were closest and arteries farthest from the placed sutures. CONCLUSION: The middle segment of the sacrospinous ligament has the lowest incidence of nerves and arteries associated with it. This study confirms that the nerves supplying the pelvic floor muscles are at a higher risk from entrapment than the pudendal nerve.

RESUMO

Background This study describes outcomes from a new surgical approach to treat "anterior" pudendal nerve symptoms in women by resecting the perineal branches of the pudendal nerve (PBPN). Methods Sixteen consecutive female patients with pain in the labia, vestibule, and perineum, who had positive diagnostic pudendal nerve blocks from 2012 through 2015, are included. The PBPN were resected and implanted into the obturator internus muscle through a paralabial incision. The mean age at surgery was 49.5 years (standard deviation [SD] = 11.6 years) and the mean body mass index was 25.7 (SD = 5.8). Out of the 16 patients, mechanisms of injury were episiotomy in 5 (31%), athletic injury in 4 (25%), vulvar vestibulectomy in 5 (31%), and falls in 2 (13%). Of these 16 patients, 4 (25%) experienced urethral symptoms. Outcome measures included Female Sexual Function Index (FSFI), Vulvar Pain Functional Questionnaire (VQ), and Numeric Pain Rating Scale (NPRS). Results Fourteen patients reported their condition pre- and postoperatively. Mean postoperative follow-up was 15 months. The overall FSFI, and arousal, lubrication, orgasm, satisfaction, and pain domains significantly improved (p < 0.05). The VQ also significantly improved (p < 0.001) in 13 (93%) of 14 patients. The NPRS score decreased on average from 8 to 3 (p < 0.0001). All four patients with urethral symptoms were relieved of these symptoms. Conclusion Resection of the PBPN with implantation of the nerve into the obturator internus muscle significantly reduced pain and improved sexual function in women who sustained injury to the PBPN.

RESUMO

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. Various medication trials only lead to limited improvement in pain. The first diagnostic right pudendal nerve block was done using 3 mL of 0.25% bupivacaine with 6mg of betamethasone using a transgluteal technique and a target of the right ischial spine; this procedure resulted in ~8 hours of > 50% pain relief. The patient was then referred for MR neurography of the lumbosacral plexus. This study revealed increased signal of the right pudendal nerve at the ischial spine and in the pudendal canal, findings consistent with the clinical picture of PN. Six weeks after the initial block, the patient underwent a second right transgluteal pudendal nerve block, utilizing 3 mL of 0.25% bupivacaine with 40 mg of triamcinolone acetonide; this procedure resulted in ~8 hours of 100% pain relief. Satisfied with these results the patient decided to undergo pudendal nerve PRF ablation for possible long-term relief. For this therapeutic procedure, a right transgluteal approach was again utilized. PRF ablation was performed for 240 seconds at 42° Celsius. Following this ablation the patient reported at least 6 weeks of significant (> 50%) pain relief. DISCUSSION AND CONCLUSION: In this paper we presented a case of successful treatment of PN with PRF ablation and detection of pudendal neuropathy on MR neurography. We believe that transgluteal PRF ablation for PN might be an effective, minimally invasive option for those patients that have failed conservative management. MR neurography employed in this case is not only helpful in confirming the diagnosis of PN but could also be useful in ruling out other causes of pelvic pain, such as genitofemoral neuropathy, endometriosis, adenomyosis, or pelvic mass lesion. To conclude, transgluteal PRF ablation can serve as a viable treatment option for mitigating symptoms of pudendal neuropathy and MR neurography is useful in confirming a clinically suspected diagnosis of PN.Key words: Pelvic pain, pudendal neuralgia, MR neurography, pulsed radiofrequency ablation, transgluteal technique, Alcock canal syndrome.

RESUMO

INTRODUCTION AND HYPOTHESIS: To avoid injury to the perineal branches of the pudendal nerve during urinary incontinence sling procedures, a thorough knowledge of the course of these nerve branches is essential. The dorsal nerve of the clitoris (DNC) may be at risk when performing the retropubic (tension-free vaginal tape) procedure as well as the inside-out and outside-in transobturator tape procedures. The purpose of this study was to identify the anatomical relationships of the DNC to the tapes placed during the procedures mentioned and to determine the influence of body variations. METHODS: In this cadaveric study, the body mass index (cBMI) of unembalmed cadavers was determined. Suburethral tape procedures were performed by a registered urologist and gynecologist on a sample of 15 female cadavers; six retropubic, seven inside-out and nine outside-in transobturator tapes were inserted. After embalmment, dissections were performed and the distances between the DNC and the tapes measured. RESULTS: In general the trajectory of the outside-in tape was closer to the DNC than that of the other tapes. cBMI was weakly and nonsignificantly correlated with the distance between the trajectory of the tape and the DNC for the inside-out tape and the tension-free vaginal tape, but not for the outside-in tape. CONCLUSIONS: The findings suggest that the DNC is less likely to be injured during the inside-out tape procedure than during the outside-in procedure, regardless of BMI. Future studies on larger samples are desirable to confirm these findings.

RESUMO

AIMS: The aim was to develop a new laparoscopic technique for placement of a pudendal lead. METHODS: Development of a direct, feasible and reliable minimal-invasive laparoscopic approach to the pudendal nerve (PN). Thirty-one embalmed human specimens were dissected for the relevant anatomic structures of the pelvis. Step-by-step documentation and analysis of the laparoscopic approach in order to locate the PN directly in its course around the medial part of the sacrospinous ligament and test this approach for feasibility. Landmarks for intraoperative navigation towards the PN as well as the possible position of an lead were selected and demonstrated. RESULTS: The visible medial umbilical fold, the intrapelvine part of the internal pudendal artery, the coccygeus muscle and the sacrospinous ligament are the main landmarks. The PN traverses the medial part of the sacrospinous ligament dorsally, medially to the internal pudendal artery. The medial part of the sacrospinous ligament has to be exposed in order to display the nerve. An lead can be placed ventrally on the nerve or around it, depending on the lead type or shape. CONCLUSIONS: A precise and reliable identification of the PN by means of laparoscopy is feasible with an easy four-step approach: (1) identification of the medial umbilical fold; (2) identification of the internal iliac artery; (3) identification of the internal pudendal artery and incision of the coccygeus muscle ('white line', arcuated line); and (4) exposition of the medial part of the sacrospinous ligament to display the PN.
