Pseudoaneurysm (PA) associated with an arteriovenous fistula (AVF) of the internal pudendal artery branches are very uncommon. We report a case of post-traumatic PA with AVF connected to Santorini plexus. Diagnosis was made with trans-rectal ultrasound (TRUS) after recurrent hematuria. TRUS reported a 1.7 × 1.4 × 1.5 cm anechoic area, on anterior prostate apex close to Santorini plexus. The use of color Doppler in this area revealed high flow velocity that was indicative for AVF. The feeding artery was a distal branch of the left pudenda artery...

BACKGROUND: Chronic pelvic, perineal and gluteal neuralgia is often experienced in a similar way to neuropathic pain, in the territories of four nerves: ilio-inguinal, pudendal, inferior cluneal and posterior gluteal nerves. These pains are often refractory to medical treatment based on the use of systemic molecules with disabling adverse effects and surgical procedure may be necessary. OBJECTIVE: The objective of this study was to evaluate the efficacy and safety of treatment with a high-concentration capsaicin patch in these indications...

BACKGROUND: Several studies have described the course and anatomical relations of the pudendal nerve. Several surgical nerve decompression techniques have been described, but only the transgluteal approach has been validated by a prospective randomized clinical trial. The purpose of this study was to describe the course of the nerve and its variants in a population of patients with pudendal neuralgia in order to guide the surgeon in the choice of surgical approach for pudendal nerve decompression...

BACKGROUND: Laparoscopic ventral rectopexy effectively treats posterior compartment prolapse. However, recurrence after laparoscopic ventral rectopexy is poorly understood. OBJECTIVE: This study aimed to evaluate factors contributing to recurrence after laparoscopic ventral rectopexy. DESIGN: A retrospective cohort analysis was performed of patients who underwent laparoscopic ventral rectopexy between June 2008 and June 2014. Patients presenting with full-thickness rectal prolapse were compared against the rest...

BACKGROUND: Cell therapy for intrinsic urinary sphincter deficiency (ISD) in women has been moderately effective, and improvements are needed. To improve treatment efficacy, it is important to better understand determinates of cell efficacy in the different patient cohorts. We have reported that in nonhuman primates the chronicity of ISD may affect cell efficacy, but additional factors (age, psychosocial stress, hormone status, body weight) can be associated with many disease/treatment outcomes in women - and these factors are the focus of this study...

The study was designed to investigate the clinical application and significance of the bulbocavernosus reflex (BCR) test for diagnosing diabetic neurogenic bladder (DNB) in female subjects. In this study, 68 female patients with DNB and 40 female normal controls were subjected to a nerve conduction study (NCS) of all four limbs and the BCR test. The data were analyzed and compared, and the corresponding diagnostic sensitivities were discussed. Mean BCR latency for female DNB patients was significantly prolonged, compared to that of the control group, suggesting pudendal nerve injuries in female DNB patients...

INTRODUCTION: Sacral nerve stimulation (SNS) is a common and effective treatment for faecal incontinence (FI), but accessibility of the sacral nerves is mandatory. In some cases, electrode placement fails for unknown reasons. A frequent cause could be sacral malformations, which have a high incidence (up to 24.1%) and can be unsuspected. METHODS AND RESULTS: We report two patients with FI consequent to congenital anorectal malformation and associated sacral malformation...

INTRODUCTION AND HYPOTHESIS: Pelvic anatomy is complex and intimate knowledge of variabilities in anatomical relationships is critical for surgeons to safely perform surgical procedures. Three-dimensional Imaging provides the opportunity to analyze undisturbed anatomical relationships. The authors hypothesized that three-dimensional models created from pelvic computed tomography angiograms could be used to obtain vascular anatomical measurements, and that the measurements obtained from three-dimensional models would be similar to those from cadaver studies...

This article is a practical review update on ultrasound (US)-guided interventional procedures on peripheral nerves. Technical considerations, biopsy techniques, and some examples of injections are described. US is considered a safe imaging guidance for interventional procedures, due to its high spatial resolution and the possibility to image the needle and inject drugs in real time. US-guided injections could be considered a diagnostic and therapeutic option in the most common neuropathy, before or as an alternative to surgery...

OBJECTIVE: The purpose of this paper was to describe patterns of superficial reflux in the groin with respect to the terminal valve (TV), which is located at the saphenous opening to the common femoral vein, the great saphenous vein, and its tributary veins. METHODS: This study included 2019 legs with chronic venous insufficiency that received endoluminal varicose vein treatment because of varicosities with insufficiency of the saphenofemoral junction (SFJ). In a preoperative duplex ultrasound investigation of the superficial vein system, reflux after provocation in the SFJ, great saphenous vein, cranial veins (superficial external pudendal vein, superficial epigastric vein, superficial circumflex iliac vein), and anterior and posterior accessory saphenous veins was recorded and classified on the basis of the origin of reflux...

This study investigated the role of γ-aminobutyric acid subtype B (GABAB) receptors in tibial and pudendal neuromodulation of bladder overactivity induced by intravesical administration of dilute (0.5%) acetic acid (AA) in α-chloralose anesthetized cats. To inhibit bladder overactivity, tibial or pudendal nerve stimulation (TNS or PNS) was applied at 5 Hz and 2 or 4 times threshold (T) intensity for inducing toe or anal sphincter twitch. TNS at 2T or 4T intensity significantly (p<0.05) increased the bladder capacity to 173...

The role of cannabinoid type 1 (CB1) receptors in tibial and pudendal neuromodulation of bladder overactivity induced by intravesical infusion of 0.5% acetic acid (AA) was determined in α-chloralose anesthetized cats. AA irritation significantly (p<0.01) reduced bladder capacity to 36.6±4.8% of saline control capacity. Tibial nerve stimulation (TNS) at 2 or 4 times threshold (T) intensity for inducing toe movement inhibited bladder overactivity and significantly (p<0.01) increased bladder capacity to 69...

Sacral neuromodulation has had a tremendous impact on the treatment of urinary incontinence and lower urinary tract symptoms for patients with neurologic conditions. This stimulation does not use real-time data from the body or input from the patient. Incorporating this is the goal of those pursuing a neuroprosthesis to enhance bladder function for these patients. Investigators have demonstrated the effectiveness of conditional (also called closed-loop) feedback in animal models as well as limited human studies...

We report a case of nonischemic priapism following brachytherapy. A 63-year-old man presented 22 days after brachytherapy for prostate cancer. He suffered painless sustained incomplete erection for a few days. The patient was diagnosed with nonischemic priapism by cavernosal blood gas analysis. Right internal pudendal arteriography showed blood pooling in the cavernosum caused by arteriovenous fistula. Selective arterial embolization with gelatin sponge particles was performed and detumescence achieved. To our knowledge,this is the first case of high flow priapism caused by brachytherapy for prostate cancer...

INTRODUCTION: Women with pelvic floor dysfunction can have tender areas on vaginal examination, which can be treated with trigger-point injections. There are no publications to evaluate the accuracy of pelvic floor muscle injections. METHODS: Trigger-point injections were performed on 2 fresh cadaveric pelvises using a curved nasal cannula guide and 7-in spinal needle. This was performed using our standard template of 2 sets of injections at the 1-, 3-, and 5-o'clock positions distally and proximally...

Jan Fritz, Benjamin Fritz, A Lee Dellon
Pelvic pain due to chronic pudendal nerve (PN) compression, when treated surgically, is approached with a transgluteal division of the sacrotuberous ligament (STL). Controversy exists as to whether the STL heals spontaneously or requires grafting. Therefore, the aim of this study was to determine how surgically divided and unrepaired STL heal. A retrospective evaluation of 10 patients who had high spatial resolution 3-Tesla magnetic resonance imaging (3T MRI) exams of the pelvis was done using an IRB-approved protocol...
