ABSTRACT
OBJECTIVE: To evaluate the effectiveness of non-pharmacological, conservative therapies for women with chronic pelvic pain (CPP). DATA SOURCES: A systematic search of electronic databases (Amed, CINAHL, PsycINFO, SportDiscuss, Medline, PubMed, Embase, and Cochrane Central Register of Controlled Trials) was performed in January 2023, and updated in December 2023. STUDY ELIGIBILITY CRITERIA: Randomized controlled trials (RCTs) comparing a non-pharmacological, conservative therapy to inert (e.g., placebo, usual care) or non-conservative (e.g., surgical, pharmacological) treatment were included. Conservative therapies of interest to this review were: multimodal physical therapy, predominantly psychological approaches, acupuncture, and other tissue-based monotherapies (e.g., electrophysical agents, manual stretching). STUDY APPRAISAL AND SYNTHESIS METHODS: All study data were aggregated, and analyses of the included studies were performed. Effects on pain; sexual measures; psychological and physical function; health-related quality of life; symptom severity/bother; pelvic floor muscle function and morphometry; perceived improvement; and adverse events were analyzed. Meta-analyses (random effects model) were conducted using post-intervention scores for data that included similar interventions and outcomes. Standardized mean differences (SMD) were calculated. A narrative summary of findings that could not be included in the meta-analysis is provided. The quality of the evidence was assessed with the PEDro scale and the certainty of evidence with Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) criteria. RESULTS: Of 5776 retrieved studies, 38 RCTs including 2168 women (mean age 35.1±8.6) were included. Meta-analyses revealed that multimodal physical therapy resulted in lower pain intensity compared to inert or non-conservative treatments in both the short (SMD -1.69, 95% CI -2.54,-0.85; high certainty) and intermediate-terms (SMD -1.82, 95% CI -3.13, -0.52; moderate certainty), while predominantly psychological approaches resulted in no difference in pain intensity (SMD -0.18, 95% CI -0.56, 0.20; moderate certainty) and a slight difference in sexual function (SMD -0.28, 95% CI -0.52,-0.04; moderate certainty). The level of evidence regarding the meta-analysis of the effects of acupuncture on pain intensity (SMD 1.08, 95% CI -1.38, 3.54, non-statistically significant results in favor of control treatment) precluded any statement of certainty. A limited number of trials investigated individual tissue-based monotherapies, providing a restricted body of evidence. CONCLUSIONS: This systematic review with meta-analysis revealed that multimodal physical therapy is effective in women with CPP with a high certainty of evidence.
ABSTRACT
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a urinary disorder that affects youthful to middle-aged men most frequently. It has been revealed that Th17/Treg imbalance is a crucial factor in the pathophysiological mechanisms behind this disease. However, this imbalance's mechanisms are unknown. In the experimental autoimmune prostatitis (EAP) mouse model, the NLRP3 inflammasome was turned on, IL-1ß levels went up. Moreover, there exists a discernible positive association between the upsurge in IL-1ß and the perturbation of Th17/Treg equilibrium. Additionally, we have revealed that IL-1ß plays a vital role in promoting the differentiation of Naïve CD4+ T cells into the Th17 cells and enhances the conversion of Treg cells into Th17 cells. Further studies revealed that IL-1ß promotes STAT3 phosphorylation, which is what causes Treg cells to become Th17 cells. All data strongly suggest that the NLRP3 inflammatory influence Th17 cell development and the conversion of Treg cells into Th17 cells through IL-1ß, disrupting the Th17/Treg balance and exacerbating EAP inflammation. In this article, we provide new theories for the pathogenesis of CP/CPPS and propose new prevention and therapy methods.

PURPOSE: To investigate the preliminary treatment outcomes of transcatheter arterial embolization (TAE) for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). MATERIALS AND METHODS: This retrospective study included patients with refractory CP/CPPS who underwent TAE between April 2022 and February 2023. All patients had persistent pelvic pain for at least 3 months, a total score of at least 15 on the NIH-Chronic Prostatitis Symptom Index (NIH-CPSI), and lacked evidence of infection. All procedures were performed by injecting imipenem/cilastatin sodium (IPM/CS) from bilateral prostatic arteries ± internal pudendal arteries. NIH-CPSI, pain numeric rating scale (NRS), and complications were evaluated at 1, 3, and 6 months after the initial TAE and at the final follow-up. RESULTS: Out of 48 patients, 44 were included in this study, with four excluded because of loss of follow-up. No severe procedure-related complications were observed. Pretreatment and post-treatment evaluations at 1, 3, and 6 months after the initial TAE and at the final follow-up (mean 16.6 months) revealed a decrease in the mean NIH-CPSI scores from 27 ± 6 to 21 ± 8, 20 ± 9, 17 ± 9, and 18 ± 9, respectively (all P < 0.001). Pain NRS scores were also decreased from 7.0 ± 1.6 to 4.8 ± 2.5, 4.1 ± 2.6, 3.7 ± 2.4, and 3.4 ± 2.3, respectively (all P < 0.001). The proportions of clinical success, defined as a reduction of at least 6 points from baseline in the NIH-CPSI, at 6 months after TAE and at the final follow-up were 70 and 64%, respectively. CONCLUSIONS: This study provides evidence of the feasibility of TAE using IPM/CS for CP/CPPS, suggesting both symptomatic improvement and safety.
ABSTRACT
INTRODUCTION: Vulvodynia is a complex and multifactorial medical condition characterized by pain in the vulvar area without any identifiable cause. Vulvodynia is underdiagnosed, leading to increased risk of sexual dysfunction and reduced quality of life. Irritable bowel syndrome (IBS) is a gastrointestinal disorder predominantly affecting women. Vulvodynia and IBS frequently co-occur in women, with a 2- to 4-fold increased likelihood of IBS diagnosis in those with vulvodynia. These conditions may share underlying causes, highlighting the need for research to better understand their shared pathophysiology and develop effective therapeutics. OBJECTIVE: The aim of this scoping review was to assess the evidence of simultaneous presentation of IBS and vulvodynia. METHODS: A comprehensive search was conducted in 6 databases between inception of database and August 2023: PubMed, Web of Science, Scopus, Science Direct, Google Scholar, and Cochrane Library. Studies included primary research about IBS and vulvodynia in terms of presentation overlap, diagnosis, or treatment. Data were extracted from eligible studies, summarized, and collated. RESULTS: Of the 306 unique articles identified, 33 were included in the final analysis: 20 cross-sectional studies, 4 case-control studies, 2 case reports, 4 cohort studies, 2 quasi-experimental studies, and 1 randomized trial. Common themes included a high prevalence of overlapping vulvodynia and IBS with a significant diagnostic delay in vulvodynia, mast cell involvement and visceral hypersensitization as common pathophysiology, and the need for a multimodal treatment. CONCLUSION: Our review adds to the evidence that there is an association between vulvodynia and IBS. Despite this, research on the underlying molecular mechanisms of this association is scarce, and diagnostic delays persist for vulvodynia. Increasing awareness of the overlap of these conditions will improve screening for vulvodynia in the patient population with IBS, thereby improving the diagnostic delay, and understanding the pathophysiology will enable treatment strategies that address both conditions.
ABSTRACT
BACKGROUND: Chronic pelvic pain (CPP) in women is a debilitating condition with symptoms that affect both medical and psychological systems, yet for those with idiopathic CPP (i.e., those without a known physiologic cause), no consensus for intervention exists. AIM: A systematic review was conducted to identify the effectiveness of current biomedical, psychosocial, and integrative interventions for idiopathic CPP (ICPP). METHOD: Five databases (PubMed, CINAHL, Cochrane, PsycInfo, Web of Science) were systematically searched with multiple keywords for publications from 2008-2022. Articles were coded for sample characteristics, research design, type of intervention, and intervention outcomes. RESULTS: Nineteen studies met criteria. The majority of the interventions (14 studies) were biomedical, either invasive (e.g., injections), or non-invasive (e.g., medications). Five studies evaluated integrative interventions that combined biomedical and psychosocial components (e.g., a multimodal pain treatment center). Invasive biomedical interventions were better at relieving short-term pain and non-invasive biomedical interventions were superior for long-term pain; integrated interventions reduced both short-term and long-term pain. Integrative interventions also improved mental health, sexual health, and QOL. CONCLUSION: Although most interventions for ICPP have been biomedical, integrative interventions showed greater outcome effectiveness, suggesting a focus on integrative interventions in the future.
ABSTRACT
To critically analyse the relationship of bladder pain syndrome (BPS/IC), as defined, to the posterior fornix syndrome, "PFS" predictably co-occurring bladder urgency, frequency, nocturia, chronic pelvic pain, emptying symptoms/retention, caused by uterosacral ligament (USL) laxity and cured by USL repair. The starting and end points of this paper are the questions, "Are there arguments that BPS/IC can, in some cases, be linked to PFS?" And if so, "To what extent?" We used the criteria required by Ueda for proper diagnosis: "understanding symptoms, detecting abnormal findings and verifying them as a cause of the symptoms." Literature, diagnostic and surgical, indicate that chronic pelvic pain "of unknown origin" can be caused by unsupported visceral pelvic plexuses because of weak USLs; these cause fire of afferent impulses, which the brain mistakenly interprets as coming from the end-organ itself (i.e., genitourinary pain, lower urinary tract symptoms). The same lax USLs can also weaken the pelvic muscles which contract to stretch the vagina to support the urothelial stretch receptors from below: these may prematurely fire off afferent impulses to activate micturition at lower bladder volumes, interpreted as urgency. A speculum placed in the vagina can relieve pain and urgency by mechanically supporting the vaginal wall and USLs, thus predicting an eventual cure by USL repair. There is need to evaluate what percentage of women with known BPS/IC also pass the criteria for PFS. Identifying a significant percentage of BPS/IC women with the causative relation between PFS pathogenesis and BPS/ IC may open a new way of diagnosing and treating BPS/IC in some women.
ABSTRACT
OBJECTIVE: To quantify the variation, triggers and impact on quality of life of symptom flares in women with chronic pelvic pain (CPP). DESIGN: Cross-sectional questionnaire within the Translational Research in Pelvic Pain clinical cohort study. SETTING: Women with CPP, with subgroups of women with endometriosis (EAP), interstitial cystitis/bladder pain syndrome (BPS), comorbid endometriosis and interstitial cystitis/bladder pain syndrome (EABP), and those with pelvic pain without endometriosis or interstitial cystitis/bladder pain syndrome (PP). POPULATION OR SAMPLE: A total of 100 participants. METHODS: Descriptive and comparative analysis from flares questionnaire. MAIN OUTCOME MEASURES: The prevalence, characteristics and triggers of short, medium and long symptom flares in CPP. RESULTS: We received 100 responses of 104 questionnaires sent. Seventy-six per cent of women with CPP have ever experienced symptom flares of at least one length (short, medium and/or long). Flares are associated with painful and non-painful symptoms. There is large variation for the frequency, duration, symptoms and triggers for flares. Over 60% of participants reported flares as stopping them from doing things they would usually do, >80% reported thinking about symptoms of flares and >80% reported flares being bothersome. CONCLUSIONS: Flares are prevalent and clinically very important in CPP. More research is needed to elucidate the mechanisms and characteristics underlying flares. Clinical practice should include an enquiry into flares with the aim of finding strategies to lessen their burden.
ABSTRACT
AIMS: (1) To use intraoperative photographs to visualize and explain pudendal nerve compressions and anatomical variations of compression sites in patients with chronic pelvic pain. (2) To emphasize the diagnostic importance of sensory examination with a safety pin at the six pudendal nerve branches in all patients with chronic pelvic pain; the dorsal nerves (penis or clitoris; the perineal nerves; and the inferior rectal nerves). METHODS: Between 2003 and 2014, "definite" pudendal neuropathy was diagnosed by examination and with two neurophysiologic tests. Neurolysis, via a transgluteal approach, was recommended only after 14 weeks of conservative care failed to adequately improve symptoms and validated symptom scores. Photographs of surgical findings were culled for their educational impact. An illustration of each photo clarifies the surgical anatomy. RESULTS: The transgluteal incision permits access to pudendal anatomy and compression sites from the subpiriformis area through the interligamentary space and the pudendal canal (Alcock canal). Compressions were acquired or congenital and severity varied significantly. Pinprick sensory testing diagnoses pudendal neuropathy in 92% of both genders. Mid-nerve compression occurred commonly between the sacrotuberous and sacrospinous ligaments less frequently in the Alcock canal, but also at aberrant pathways, for example, between layers of the sacrotuberous ligament; a separate inferior rectal nerve passing through the sacrospinous ligament; at an anomalous lateral pathway posterior to the ischial spine. The results of international surgeons are discussed. CONCLUSIONS: Decompression surgery was recommended in approximately 35% of patients in this practice, when pudendal neuropathy (pudendal syndrome), did not respond to two conservative levels of treatment: (1) nerve protection and medications and, (2) a series of three pudendal nerve perineural injections given at 4-week intervals. Significant nerve compression is consistently observed. Pathophysiology includes axonopathy from ischemia and demyelination. Neuropathy is readily diagnosed using a pinprick sensory examination of six pudendal nerve branches. Monitoring with the National Institutes of Health Chronic Prostatitis Symptom Index records cures >13 years.
ABSTRACT
BACKGROUND: Loss of Intra Uterine Device (IUD) following silent perforation of the uterus either during or after IUD insertion is an uncommon finding due to a lack of immediate follow-up. We report a rare case in which uterine perforation following the migration of IUD to the right fallopian tube without visceral injury. The patient presented with lower abdominal pain and pain during sex for one year since IUD insertion. On examination, we noted tenderness on the right suprapubic region and on speculum examination, no IUD thread was seen. A radiological pelvic examination showed an empty uterus without an IUD. Laparotomy and retrieval of migrated IUD was done followed by repair of perforated uterus. CONCLUSION: Migrated IUD with silent uterine perforation without visceral injury is a distressing clinical condition both to the patient and the clinician. This case is reported to increase awareness in doing immediate vaginal examination and pelvic ultrasound post-IUD insertion.
ABSTRACT
Endometriosis is a chronic proinflammatory pathology characterized by the growth of tissue similar to the endometrium outside the uterus, affecting approximately 5 to 15% of women worldwide. Suffering from endometriosis entails a complex pathophysiological process, significantly impacting the quality of life and reproductive function of affected women; therefore, it must be addressed in a personalized and comprehensive manner, as its management requires a multidisciplinary approach. This article aims to conduct a comprehensive literature review of endometriosis, not only as a pathophysiological condition but also as a significant factor impacting the social, nutritional, and mental well-being of those who experience it. Emphasis is placed on the importance of understanding and assessing the impact of the pathology to provide a better and more comprehensive approach, integrating various alternatives and strategic treatments for the factors involved in its development. The aim is to provide a complete overview of endometriosis, from its pathophysiology to its impact on the quality of life of patients, as well as a review of current treatment options, both pharmacological and alternative, in order to broaden the perspective on the pathology to improve the care of patients with this disease.
ABSTRACT
BACKGROUND: There are limited data on pelvic pain among transgender men and gender diverse people, and the impact of testosterone on pelvic pain is poorly understood. OBJECTIVE: Characterize the prevalence and correlates of chronic pelvic pain (CPP) among transgender men and gender diverse people and examine the association between testosterone use and CPP. MATERIALS AND METHODS: We used 2020-2022 data from The Population Research in Identity and Disparities for Equality (PRIDE) Study, an online prospective cohort study of sexual and gender minority adults in the United States, to conduct complementary cross-sectional and longitudinal analyses. Our primary outcome was self-reported CPP lasting 3 months or longer measured using the Michigan Body Map. RESULTS: Among 2579 transgender men and gender diverse people assigned female at birth included in our sample, 457 (18%) reported CPP. CPP correlates included: inflammatory bowel disease, irritable bowel syndrome (IBS), kidney stones, pelvic inflammatory disease, polycystic ovary syndrome (PCOS), uterine fibroids, current hormonal intrauterine device use, prior pregnancy, vaginal delivery, hysterectomy, and oophorectomy. Individuals with CPP reported a high prevalence of IBS (37%), PCOS (20%), uterine fibroids (9%), post-traumatic stress disorder (51%), and severe depression and anxiety symptoms (42% and 25%, respectively). Current testosterone use was associated with a 21% lower prevalence of CPP (adjusted prevalence ratio (aPR) 0.79, 95% confidence interval [CI]: 0.65-0.96). In longitudinal analyses (N = 79), 15 (19%) participants reported any CPP after initiating testosterone: eight (56%) of whom reported CPP prior to testosterone initiation, and seven (47%) who reported new-onset CPP. DISCUSSION AND CONCLUSIONS: The relationship between CPP and testosterone is complex. Although testosterone use was associated with a lower prevalence of CPP, some transgender and gender diverse individuals experienced new-onset pelvic pain after testosterone initiation. Given the significant impact that CPP can have on mental health and quality of life, future research must examine the role of testosterone in specific underlying etiologies of CPP and identify potential therapies.
ABSTRACT
Background Recent research has suggested a role for mindfulness-based therapy for patients with chronic medical conditions, but there is limited data on pelvic pain. We aim to determine if mindfulness improves patient-reported outcomes in pelvic pain and to determine the feasibility of implementation of this program. Methodology This is a pilot feasibility trial consisting of women with chronic pelvic pain at a single academic tertiary referral clinic. A convenience sample of 15 subjects was enrolled. Subjects were scheduled for three 60-minute virtual mind-body sessions with a certified counselor. Baseline scores were obtained using the Patient-Reported Outcomes Measurement Information System-Computer Adaptive Testing (PROMIS-CAT) platform. They were repeated three months and six months after enrollment. Descriptive statistics were performed. Results A total of 15 patients were enrolled in the study. Among the 13 patients who completed the three-month PROMIS-CAT scores, seven had a clinically significant 5-point improvement in sleep disturbance T-score. At least a 5-point improvement in fatigue, pain interference, and ability to participate in social roles and activities T-scores were observed in six patients each. There was a 40% dropout rate. Conclusions A formal mind-body counseling program can support patients with chronic pelvic pain. Our trial demonstrated the feasibility of establishing a program and modest improvement in patient-reported quality of life.
ABSTRACT
Pelvic venous reflux and obstruction can lead to chronic pelvic pain and extra-pelvic varicosities. This paper will discuss the contemporary understanding of this pathophysiology and its clinical manifestations. It will review evidence-based clinical and imaging criteria of pelvic venous disorders, data supporting benefit from venous interventions, criticisms of the available data and highlight evidence research gaps that exist. Finally, it will argue that comparative outcomes research utilizing standardized patient selection for embolization and stenting, embolization treatment strategies that eliminate the pelvic varices (at least to start), and clinically relevant outcome measures are necessary to establish the benefit of vascular treatments.
ABSTRACT
BACKGROUND: Many genitourinary tract disorders could be attributed partly to the microbiota. This study sought to conduct a systematic review of the role of the microbiota in urinary chronic pelvic pain syndrome (UCPPS). METHODS: We searched Embase, Scopus, Web of Science, and PubMed with no time, language, or study type restrictions until December 1, 2023. The JBI Appraisal Tool was used to assess the quality of the studies. Study selection followed the PRISMA statement. Studies addressing microbiome variations among patients suffering from interstitial cystitis/bladder pain syndrome (IC/BPS) or chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and a control group were considered eligible. RESULTS: A total of 21 studies (1 UCPPS, 12 IC/BPS, and 8 CP/CPPS) comprising 1125 patients were enrolled in our final data synthesis. It has been shown that the reduced diversity and discrepant composition of the gut microbiota may partly be attributed to the UCPPS pathogenesis. In terms of urine microbiota, some operational taxonomic units were shown to be elevated, while others became less abundant. Furthermore, various bacteria and fungi are linked to specific clinical features. Few investigations denied UCPPS as a dysbiotic condition. CONCLUSIONS: Urinary and intestinal microbiota appear to be linked with UCPPS, comprising IC/BPS and CP/CPPS. However, given the substantial disparity of published studies, a battery of prospective trials is required to corroborate these findings.
ABSTRACT
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common pelvic pain syndrome in males, seriously affecting patients' quality of life. For a long time, CP/CPPS has been considered a complex and variable disease, and its pathogenesis remains incompletely understood. Currently, CP/CPPS is believed to be a group of diseases characterized by pelvic pain or discomfort, urinary abnormalities, and other symptoms, each with its unique etiology, clinical characteristics, and outcomes, likely resulting from the action of pathogens or (and) certain non-infectious factors. Traditionally, CP/CPPS was thought to be unrelated to bacterial infections. However, in recent years, with the development of microbiology and the advancement of high-throughput sequencing technology, an increasing number of studies have suggested that microorganisms in the reproductive system may play an important role in the pathogenesis of CP/CPPS. The unique characteristics of CP/CPPS, such as its refractory nature and tendency to recur, may be closely related to the microbiota and their biological functions in the reproductive system. The relationship between CP/CPPS and reproductive system microorganisms is one of the current hot topics in microbiology and urology, receiving considerable attention from scholars in recent years and making a series of new advances. Through this review, we will comprehensively explore the relationship between CP/CPPS and reproductive system microorganisms, and look forward to future research directions, aiming to provide new ideas and methods for clinical diagnosis and treatment, thereby improving the treatment outcomes and quality of life of CP/CPPS patients.

BACKGROUND: The prominent symptoms of chronic pelvic pain syndrome (CPPS) are urogenital pain, lower urinary tract symptoms, psychological problems, and sexual dysfunction. Traditional pharmacological treatments have poor efficacy and more untoward reaction and complications. Magnetic vibration magnetoelectric therapy is a non-invasive form of physiotherapy. Nevertheless, its effectiveness in improving urinary discomfort and relieving pain in patients requires further exploration. AIM: To investigate the clinical efficacy of the magnetic vibration magnetoelectric therapy instrument in the treatment of chronic prostatitis (CP)/ CPPS. METHODS: Seventy patients with CP/CPPS were collected from the outpatient clinic and ward of the Department of Male Medicine, Jiangsu Province Hospital of Traditional Chinese Medicine, and were treated with magnetic vibration magnetoelectric therapy once a day for a period of 14 d. National Institutes of health-chronic prostatitis symptom index (NIH-CPSI), international index of erectile function 5 (IIEF-5), premature ejaculation diagnostic tool (PEDT), generalized anxiety disorder (GAD), patient health questionnaire, the pain catastrophizing scale (PCS) and traditional Chinese medicine syndrome (TCMS) scores were performed before and after treatment. RESULTS: The total effective rate of treatment was 58.5%, and the total NIH-CPSI score, pain symptoms, voiding symptoms, quality of life, IIEF-5, PEDT, GAD, PCS and TCMS scores all decreased significantly (P < 0.05). CONCLUSION: Magnetic vibration magnetotherapy is effective in improving urinary discomfort, relieving pain, improving quality of life, improving sexual dysfunction and relieving negative emotions such as anxiety in patients with CP/CPPS.
ABSTRACT
BACKGROUND: Chronic pelvic pain (CPP) is a multifactorial syndrome that can substantially affect a patient's quality of life. Endometriosis is one cause of CPP, and alterations of the immune and microbiome profiles have been observed in patients with endometriosis. The objective of this pilot study was to investigate differences in the vaginal and gastrointestinal microbiomes and cervicovaginal immune microenvironment in patients with CPP and endometriosis diagnosis compared to those with CPP without endometriosis and no CPP. METHODS: Vaginal swabs, rectal swabs, and cervicovaginal lavages (CVL) were collected among individuals undergoing gynecologic laparoscopy. Participants were grouped based on patients seeking care for chronic pain and/or pathology results: CPP and endometriosis (CPP-Endo) (n = 35), CPP without endometriosis (n = 23), or patients without CPP or endometriosis (controls) (n = 15). Sensitivity analyses were performed on CPP with endometriosis location, stage, and co-occurring gynecologic conditions (abnormal uterine bleeding, fibroids). 16S rRNA sequencing was performed to profile the microbiome, and a panel of soluble immune mediators was quantified using a multiplex assay. Statistical analysis was conducted with SAS, R, MicrobiomeAnalyst, MetaboAnalyst, and QIIME 2. RESULTS: Significant differences were observed between participants with CPP alone, CPP-Endo, and surgical controls for body mass index, ethnicity, diagnosis of ovarian cysts, and diagnosis of fibroids. In rectal microbiome analysis, both CPP alone and CPP-Endo exhibited lower alpha diversity than controls, and both CPP groups revealed enrichment of irritable bowel syndrome-associated bacteria. CPP-Endo exhibited an increased abundance of vaginal Streptococcus anginosus and rectal Ruminococcus. Patients with CPP and endometrioma (s) demonstrated increased vaginal Streptococcus, Lactobacillus, and Prevotella compared to other endometriosis sites. Further, abnormal uterine bleeding was associated with an increased abundance of bacterial vaginosis-associated bacteria. Immunoproteomic profiles were distinctly clustered by CPP alone and CPP-Endo compared to controls. CPP-Endo was enriched in TNFâº, MDC, and IL-1âº. CONCLUSIONS: Vaginal and rectal microbiomes were observed to differ between patients with CPP alone and CPP with endometriosis, which may be useful in personalized treatment for individuals with CPP and endometriosis from those with other causes of CPP. Further investigation is warranted in patients with additional co-occurring conditions, such as AUB/fibroids, which add additional complexity to these conditions and reveal the enrichment of distinct pathogenic bacteria in both mucosal sites. This study provides foundational microbiome-immunoproteomic knowledge related to chronic pelvic pain, endometriosis, and co-occurring gynecologic conditions that can help improve the treatment of patients seeking care for pain.

OBJECTIVE: To systematically review the classification systems for male chronic pelvic pain (CPP). METHODS: The Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica dataBASE (EMBASE), and Web of Science were searched. Any publication, with no restriction to publication date, was eligible. Publications had to propose a classification system for CPP in males or provide additional information of a system that had been identified. Systems were assessed with an adapted Critical Appraisal of Classification Systems tool. RESULTS: A total of 33 relevant publications were identified, with 22 proposing an original classification system. Systems aimed to: (i) diagnose CPP and/or differentially diagnose CPP from other conditions, (ii) differentially diagnose subtypes within CPP, or (iii) identify features that could inform underlying mechanisms and/or treatment selection. Conditions referred to as chronic prostatitis/chronic pelvic pain syndrome and interstitial cystitis/bladder pain syndrome were most represented. Clinical signs/symptoms, pathoanatomical investigations, and presumed pain mechanisms were used for classification. Quality of systems was low to moderate, implying limitations to consider for their interpretation. CONCLUSIONS: Many classification systems for CPP in males exist. Careful consideration of their intended purpose is required. Future work should examine whether outcomes for patients are improved when decisions are guided by their use.
ABSTRACT
Endometriosis-related pain may be associated with depressive symptoms. Although a growing body of evidence supports this association, the underlying mechanisms are still largely unclear. Impaired perceptions of bodily external and internal stimuli may be involved in this process. This study aims to assess the mediating role of 2 facets of interoception-the awareness of negative body signals and interoceptive self-regulation-in the association between pain severity and depressive symptoms among women with endometriosis. A total of 301 patients who reported a diagnosis of endometriosis were recruited from an endometriosis and chronic pelvic pain outpatient university clinic and through patient associations and completed self-reported instruments. A parallel mediation analysis was conducted. Almost half of women (48.2%) reported depressive symptoms above the self-rating scale cutoff values. Pain severity significantly predicted depressive symptoms (ß = .39, 95% bootstrap confidence interval [CI] [.719, 1.333]). Negative body awareness (ß = .121, 95% bootstrap CI [.174, .468]) and interoceptive self-regulation (ß = .05, 95% bootstrap CI [.035, .252]) partially mediated this relationship. Our findings indicated that pain may interfere with the perception of the body as a source of calmness and safety, limiting the individual's ability to effectively regulate emotions. Future research should further explore these mechanisms and evaluate the efficacy of interventions focusing on interoceptive sensibility to enhance the psychological well-being of endometriosis patients. PERSPECTIVE: This article investigates for the first time the potential role of 2 facets of interoceptive sensibility in the relationship between pain severity and depressive symptoms in women with endometriosis. These findings may contribute to advancing knowledge about the mechanisms involved in the complex pain-depression cycle.
ABSTRACT
BACKGROUND: Pelvic congestion syndrome (PCS) is a poorly understood condition that can be associated with chronic pelvic pain and could impact quality of life. The diagnosis is often made by exclusion of other causes of pelvic pain. OBJECTIVE: The purpose of our review was to provide an update on the etiology, anatomy, physiology, identification, and the therapeutic management of PCS. METHOD: We conducted a literature review involving publications from 2003 to 2024 in PubMed, Elsevier, MEDLINE, as well as manual searches of primary and review articles using keywords such as "pelvic veins", "embolization", "venography", "pelvic congestion syndrome", and "chronic pelvic pain". CONCLUSION: PCS remains poorly understood. Symptoms can be non-specific and difficult to distinguish from other diseases; yet it is an important cause of chronic pelvic pain in women. To date, there have been only a small number of randomized trials and high-level evidence is still lacking. OUTLOOK: We call for an increased awareness of PCS and additional clinical studies in a large number of patients.
