International Neurourology Journal 2017;21(4):243-246
Chronic pelvic pain (CPP) is a common condition involving multiple, organ-specific medical specialties, each with its own approach to diagnosis and treatment. Management requires knowledge of the interplay between pelvic organ function and neuro-functional anatomy, and of the neurologic and psychological aspects of CPP, but no current specialty fully encompasses this approach. Neuropelveology is an emerging discipline focusing on pathologies of the pelvic nervous system on a cross-disciplinary basis. It involves a neurological/neurosurgical approach, combining the knowledge required for a proper neurologic diagnosis, confirmation by transvaginal/transrectal examination of the pelvic nerves, and advanced laparoscopic surgery in selected cases of CPP. The management of CPP requires multidisciplinary contributions, and neuropelveology may offer an educational framework for the interdisciplinary exchange of knowledge between clinical physicians and basic researchers.

2.Update on the Pathology and Diagnosis of Interstitial Cystitis/Bladder Pain Syndrome: A Review.
International Neurourology Journal 2016;20(1):13-17
Interstitial cystitis/bladder pain syndrome (IC/BPS) is characterized by bladder discomfort, urinary frequency, urgency, and pelvic pain. The etiology and pathogenesis of this condition is still unknown and remains diagnosed by exclusion. The histologic findings are also neither specific for diagnosis nor correlated with symptoms. However, the definition and diagnostic criteria for the condition was established in the last decade. In this paper, we review the changes in the definition, terminology, and diagnostic scheme of IC/BPS, and summarize the histologic findings. We also briefly discuss some new pathologic suggestions and new urinary markers, focusing on the most promising ones.

Enigmatic chronic pelvic pain is the persistence of unexplained pain in the low abdomen and pelvic lesions without evidence of active disease. One of the most frequent causes is the nonvisceral pain such as myofascial and postsurgical incisional origin. We evaluated the trigger point injection of bupivacaine hydrochloride as a treatment option for chronic nonvisceral pelvic pain. From March, 1995 to May, 1996, 35 female patients (16 to 68 years old, mean 43.7 years ) with localized chronic pelvic pain for 6 months to 10 years were managed by trigger point injection. After confirming the absence of intraabdominal pathology by physical examination and Carnett`s test, 3 to 5 ml of 0.25% bupivacaine hydrochloride was injected to the most hyperpathic foci with 22 gauge, one and half inch needle percutaneously. The mean followup time was 9.7 months. The results were assessed by Visual Analogue Scale(VAS) and subjective symptoms. Twenty six patients had nonincisional pain and 9 had incisional pain. Twenty two patients were treated by only one session while others needed two or more sessions(maximum 4 sessions). The sites of pain were hypogastrium, suprapubic area and iliac fossa in the order of frequency. The mean VAS value at the time of last followup was reduced to 1.7 cm(0 - 5.7 cm) from 6.7 cm(4.9 - 9.1 cm). The improvement of pain occurred mostly within 1 week after treatment and was maintained thereafter. Eighty percent of patients expressed more than 50% reduction of pain by VAS. Sixteen patients(45.7%) responded ""pain free"", 10(28.6%) ""occasional"", 6(17.1%)"" present but better"", and 3(8.6%) ""no change"". The successful responses were noted in 74.3%. No significant complications were identified. These results demonstrated that the trigger point injection is an easy, safe and effective treatment option for chronic nonvisceral pelvic pain.

BACKGROUNDEndometriosis is a controversial and enigmatic disease. Deep infiltrating endometriosis (DIE) is responsible for painful symptoms and is the least understood type of endometriosis. Little work has been devoted to define the location of DIE lesions and its relationships with pain. The aim of the study was to investigate the relationship between the anatomical distribution of DIE lesions and pain symptoms.
METHODSClinical data from 354 patients between May 2003 and December 2007 with laparoscopically diagnosed endometriosis were collected including 177 DIE patients and 177 non-DIE patients. The pain symptoms, including dysmenorrhea (DM), chronic pelvic pain (CPP, defined as intermittent or permanent pelvic pain, not related to the menstruation and longer than 6 months), deep dyspareunia (pelvic pain at intercourse) and dyschezia (pelvic pain with defecation), were recorded for every patient before operation. Endometriotic lesions were recorded by their anatomical distributions, the depth of infiltration and lesion colors. And the relationship between the anatomical distribution of DIE lesions and pain symptoms was analyzed. Pearson's chi-square test or Fisher's exact test, one-way analysis of variance (ANOVA) and linear regression and binary Logistic regression were used for statistical analysis.
RESULTSThe duration ((13.79 ± 3.94) years) of pain suffering in DIE patients was much longer than that of non-DIE patients (P < 0.01). In DIE patients, 60.7% of the uterosacral ligament (USL) nodules were bilateral (P < 0.01); 44.6% of the cul-de-sacs were completely blocked. Rectum invasion was observed in 19.9% of DIE patients (P = 0.03); pelvic adhesion was also more common. Up to 98.41% of the deep infiltrative lesions were located in the posterior pelvic compartment. DIE lesions were also found in bladder (1.58%), USL (67.08%), cul-de-sac (12.02%), recto-vaginal septum (12.66%), rectum and rectosigmoid junction (2.85%) and ureter (3.80%). The odds ratio of USL-DIE for CPP, deep dyspareunia, dyschezia were 2.52, 1.29 and 2.24 respectively. And the depth of infiltration correlated with the severity of dysmenorrhea.
CONCLUSIONSDIE lesions were associated with severe pain symptoms. The main distribution of DIE lesions was in the posterior pelvic compartment, and was more widespread and severe in DIE patients. Moreover, resection of these DIE lesions are very important to treat the pain symptoms.

The development of leiomyomas on the grounds of an aplastic/hypoplastic uterus in patients with Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) has been rarely described. We report the first case of development of multiple leiomyomas in a patient with MRKHS complicated with pulmonary valve stenosis, and we present a narrative review of the existing literature. A 44-year-old patient with MRKHS attended our clinic because of pelvic pain, which was attributed to a pelvic mass found on ultrasound. Magnetic resonance imaging revealed a multinodular mass, indicating either ovarian pathology or the presence of leiomyomas. Exploratory laparotomy was performed, and multiple solid masses on the grounds of two rudimentary uterine buds were observed. Histological analysis revealed multiple leiomyomas arising from parametrial or paratubal tissue. We searched medical databases for articles relevant to leiomyomas and MRKHS. We present a review of the current literature and summarize the clinical manifestation, diagnosis, management, and histopathological findings of all the cases described. We underline that it is important for gynecologists to be aware of this rare clinical entity, and symptomatic leiomyomas cannot be excluded in patients with MRKHS.

8.Research advances on the role of mast cells in pelvic pain of endometriosis.
Journal of Zhejiang University. Medical sciences 2013;42(4):461-463
Endometriosis (EMs) is a common gynecologic disease that affects women's physical and mental health seriously. The pathogenesis is still unknown and the mechanism of endometriosis-associated pain remains unclear. Mast cells (MC) are known to be multifunctional players in the immune system. Recent studies have shown that nerve fibers in EMs lesions can release neural peptides such as nerve growth factor and substance P to induce MC degranulating and releasing histamine, proteases, cytokines, chemokines etc., which contributes to the development of pain and hyperalgesia in patients with endometriosis.

Cowper's syringoceles are uncommon, usually described in children and most commonly limited to the ducts. We describe more complex variants in an adult population affecting with varying degrees of severity, the glands themselves, and the complications they may lead to. One hundred consecutive urethrograms of patients with unreconstructed strictures were reviewed. Twenty-six patients (mean age: 41.1 years) with Cowper's syringoceles who were managed between 2009 and 2016 were subsequently evaluated. Presentation, radiological appearance, treatment (when indicated), and outcomes were assessed. Of 100 urethrograms in patients with strictures, 33.0% demonstrated filling of Cowper's ducts or glands, occurring predominantly in patients with bulbar strictures. Only 1 of 26 patients with non-bulbar strictures had a visible duct/gland. Of 26 symptomatic patients, 15 presented with poor flow. In four patients, a grossly dilated Cowper's duct obstructed the urethra. In the remaining 11 patients, a bulbar stricture caused the symptoms and the syringocele was identified incidentally. Eight patients presented with perineal pain. In six of them, fluoroscopy and magnetic resonance imaging (MRI) revealed complex multicystic lesions within the bulbourethral glands. Four patients developed perineoscrotal abscesses. In the 11 patients with strictures, the syringocele was no longer visible after urethroplasty. In three of four patients with urethral obstruction secondary to a dilated Cowper's duct, this resolved after transperineal excision (n = 2) and endoscopic deroofing (n = 1). Five of six patients with complex syringoceles involving Cowper's glands were excised surgically with symptomatic relief in all. In conclusion, Cowper's syringocele in adults is more common than previously thought and may cause lower urinary tract symptoms or be associated with serious complications which usually require surgical treatment.

We investigated the therapeutic effects of superoxide dismutase (SOD) from thermophilic bacterium HB27 on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and its underlying mechanisms. A Sprague-Dawley rat model of CP/CPPS was prepared and then administered saline or Thermus thermophilic (Tt)-SOD intragastrically for 4 weeks. Prostate inflammation and fibrosis were analyzed by hematoxylin and eosin staining, and Masson staining. Alanine transaminase (ALT), aspartate transaminase (AST), serum creatinine (CR), and blood urea nitrogen (BUN) levels were assayed for all animals. Enzyme-linked immunosorbent assays (ELISA) were performed to analyze serum cytokine concentrations and tissue levels of malondialdehyde, nitric oxide, SOD, catalase, and glutathione peroxidase. Reactive oxygen species levels were detected using dichlorofluorescein diacetate. The messenger ribonucleic acid (mRNA) expression of tissue cytokines was analyzed by reverse transcription polymerase chain reaction (RT-PCR), and infiltrating inflammatory cells were examined using immunohistochemistry. Nuclear factor-κB (NF-κB) P65, P38, and inhibitor of nuclear factor-κBα (I-κBα) protein levels were determined using western blot. Tt-SOD significantly improved histopathological changes in CP/CPPS, reduced inflammatory cell infiltration and fibrosis, increased pain threshold, and reduced the prostate index. Tt-SOD treatment showed no significant effect on ALT, AST, CR, or BUN levels. Furthermore, Tt-SOD reduced inflammatory cytokine expression in prostate tissue and increased antioxidant capacity. This anti-inflammatory activity correlated with decreases in the abundance of cluster of differentiation 3 (CD3), cluster of differentiation 45 (CD45), and macrophage inflammatory protein 1α (MIP1α) cells. Tt-SOD alleviated inflammation and oxidative stress by reducing NF-κB P65 and P38 protein levels and increasing I-κBα protein levels. These findings support Tt-SOD as a potential drug for CP/CPPS.
