Abstract
Bladder Pain Syndrome (BPS) is a puzzling and complicated disorder. 12 such patients, with a mean age 48.3 years, were treated with weekly intravesical instillation of admixture of alkalinized lidocaine, bupivacaine, heparin and steroids for six weeks. Evaluating the benefits of this therapy, patients experienced 82.2% & 90.9% relief at 3rd & 6th week of instillation. After completion of six cycles of therapy, patients experienced 68.7% & 65.3% relief at 3rd & 6th month follow up, concluding the early and long term relief of BPS.

Abstract
Intravesical botulinum toxin A (BoNT-A) injections are included in the interstitial cystitis/bladder pain syndrome (IC/BPS) treatment guidelines. However, the IC phenotype suitable for treatment with BoNT-A has not been clarified. Therefore, we identified the factors influencing treatment outcomes for intravesical BoNT-A injections in patients with non-Hunner IC/BPS (NHIC). This retrospective study included patients with NHIC who underwent 100 U BoNT-A intravesical injections over the past two decades. Six months after treatment, treatment outcomes were assessed using the Global Response Assessment (GRA). Outcome endpoints included GRA, clinical symptoms, urodynamic parameters, urine biomarkers, and the identification of factors contributing to satisfactory treatment outcomes. The study included 220 patients with NHIC (42 men, 178 women). The satisfactory group (n = 96, 44%) had significantly higher pain severity scores and IC symptoms index, larger maximum bladder capacity (MBC), and lower 8-isoprostane levels at baseline. Logistic regression revealed that larger MBC (≥760 mL) and bladder pain predominance were associated with satisfactory outcomes after BoNT-A injection. Subjective parameters and pain severity scores improved significantly in patients with bladder pain-predominant IC/BPS after BoNT-A injection. Thus, NHIC patients with bladder or pelvic pain are more likely to experience satisfactory outcomes following intravesical BoNT-A injections.

Abstract
INTRODUCTION Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic painful bladder condition characterized by pelvic pain and urinary symptoms without another identifiable cause. Cystoscopy as primary initial investigation for IC/BPS has not been accepted yet and needs more studies to definitely conclude. AIMS AND OBJECTIVES We aimed to assess cystoscopy findings in patients of interstitial cystitis/bladder pain syndrome and to prove role of cystoscopy as primary initial investigation for interstitial cystitis/bladder pain syndrome. MATERIALS AND METHODS Our prospective observational study included 35 female patients aged 18-69 years presenting to the Urology OPD at SMS Hospital with suprapubic or pelvic pain for 6 months, bladder pain that worsens with bladder filling and reduced with voiding, dysuria, urinary frequency and urgency, nocturia, dyspareunia. Those with history of bladder capacity more than 350 ml, duration of symptoms less than 6 months, day time frequency less than eight times per day, diagnosis of bacterial cystitis or prostatitis, bladder or ureteral calculi, active genital herpes, any existing urological malignancy, radiation cystitis were excluded from the study. They were then subject to cystoscopy and the findings of the cystoscopy were analyzed. RESULTS Out of the 35 patients, 11 (31.43%) had a normal cystoscopy. Of the 24 patients (68.57%) who had a positive cystoscopy, cystoscopy in seven patients (20.0%) revealed an ulcer. All these seven patients underwent fulguration. In the remaining 17 patients the abnormal findings were petechiae, large submucosal bleed. The sensitivity of cystoscopy in detecting the ulcerative type of Interstitial cystitis was found to be 20.0%. CONCLUSION Our study found that Cystoscopy, if employed in initial investigation can help early detection of ulcerative variety of IC/BPS and can act as therapeutic modality by using fulguration plus hydrodistension. Larger comparative studies are needed for diagnostic/Therapeutic value of cystoscopy.

Abstract
PURPOSE We aimed to illustrate the importance of cystoscopy for the diagnosis and prognosis of bladder pain syndrome (BPS) or interstitial cystitis (IC). METHODS AND MATERIALS We designed a 4-year prospective follow-up study. Patients who underwent cystoscopy between May 2011 and July 2021 with a diagnosis of BPS/IC before surgery or positive cystoscopic findings during initial surgery at Peking University People's Hospital were enrolled. Data related to symptom recurrence were obtained through clinic visits and telephone follow-up. We compared the differences in clinical features of BPS/IC subtypes differentiated by cystoscopy and first created clinical predictive nomograms for BPS/IC. RESULTS A total of 141 patients were included. There was an 8.51% chance of BPS/IC being misdiagnosed as other diseases or other diseases being misdiagnosed as BPS/IC without cystoscopy. Patients with HIC had higher pain scores and ICPI, higher residual urine volume, lower first-sense-to-void, and maximum cystometric bladder capacities than NHIC. Nomogram Models showed that patients who with higher ICPI, ICSI and lower AMBC have a greater recurrence probability, and lesions in the trigone may indicate a greater likelihood of recurrence than lesions in other bladder walls. CONCLUSIONS Timely detection of bladder cancer and other diseases using cystoscopy can avoid poor treatment effects. BPS/IC subtypes can be classified according to mucosal changes under cystoscopy. Lesions in the bladder triangle can indicate a higher recurrence risk, which is important in follow-up treatment. We strongly recommend that cystoscopy should be included in the international BPS/IC diagnostic criteria.

Comparison of the Clinical Efficacy and Adverse Events between Intravesical Injections of Platelet-Rich Plasma and Botulinum Toxin A for the Treatment of Interstitial Cystitis Refractory to Conventional Treatment. Toxins (Basel) 2023; 15:toxins15020121. [PMID: 36828435 PMCID: PMC9961286 DOI: 10.3390/toxins15020121] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 01/19/2023] [Accepted: 01/31/2023] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Intravesical injection of Botulinum toxin A (BoNT-A) and platelet-rich plasma (PRP) have been reported to alleviate bladder pain and decrease nocturia in patients with refractory interstitial cystitis/bladder pain syndrome (IC/BPS). Both treatments are novel and there has no comparison between them. This study compared the therapeutic effects and adverse events between IC/BPS patients receiving PRP or BoNT-A injections. MATERIALS AND METHODS This study retrospectively analyzed female patients with IC/BPS who were refractory to conventional treatment and received BoNT-A (n = 26) or PRP (n = 30) injections within the previous two years. Patients were arbitrarily treated with four monthly injections of PRP or a single injection of 100 U of BoNT-A. All injections were followed by cystoscopic hydrodistention. The primary endpoint was the global response assessment (GRA), and secondary endpoints were changes in the O'Leary-Sant IC symptom score, visual analog score (VAS) of bladder pain, voiding diary, and uroflow measures from baseline to six months after the first injection day. RESULTS The baseline demographics revealed no significant difference between groups. The GRA at one, three, and six months was similar between groups. A significant improvement in IC symptom scores was noted in both groups. Although VAS was significantly improved in overall patients, no significant difference was noted between the PRP and BoNT-A groups at 6 months. Only half of the study cohort had a GRA ≥2 at six months. An increase in the post-void residual was noted one month after the BoNT-A injection, but there was no difference between groups at three and six months. More patients reported dysuria (19.2% vs. 3.3%, p = 0.086) and urinary tract infection (UTI, 15.4% vs. 0%, p = 0.041) after BoNT-A injection than after the PRP injections. The time from the first injection to receiving alternative treatment was similar between groups. CONCLUSION Both intravesical PRP and BoNT-A injections have similar efficacy in IC symptom improvement. However, only half of the study cohort had a GRA of ≥2 at the six-month follow-up BoNT-A injection carries a potential risk of UTI after treatment.

Abstract
AIMS Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic inflammatory condition of the bladder. However, there are only a few medicines that are of pharmaceutical grade and reliably effective for IC/BPS symptoms. Choreito (CRT) is a pharmaceutical-grade Kampo medicine and has been widely prescribed for patients of lower urinary tract symptoms (LUTS) and BPS in Japan. In this study, we exploratory investigated the effects of CRT on the IC/BPS-like symptoms induced by tranilast. METHODS The rat IC/BPS-like model was induced by feeding administration with 0.4% tranilast. The rats were divided into the three following treatment groups: normal diet (Normal), tranilast treatment (Control), and the groups of 1% CRT (CRT) treatment for IC/BPS-like model. After 4 weeks, continuous cystmetry, locomotor, and vascular permeability was assessed. Furthermore, the cytokine levels in bladder were analyzed by the Bio-Plex suspension array system and plasma monoamine were measured. RESULTS Control group exhibited 14.3% decrease of locomotor activity in the dark period, and which were 20.3% increase by 1%CRT treatment. The voiding interval was shorter in control than in other groups. 1%CRT suppressed the shortening of voiding interval. Evans blue leakage of bladder wall observed 44.8% higher in control group than in the normal group. The leakage of 1%CRT group was 33.3% less than in the control group. The cytokine level of IFNγ and VEGF were elevated in the control, and CRT treatment suppressed the elevation of IFNγ in the bladder. Plasma noradrenaline was significantly reduced by CRT treatment compared normal group. CONCLUSION These results suggest that CRT can be an effective therapeutic agent for the treatment of IC/BPS-like symptoms.

Abstract
Botulinum toxin A (BoNT-A) is effective in reducing bladder hypersensitivity and increasing capacity through the effects of anti-inflammation in the bladder urothelium; however, studies on the treatment outcome of interstitial cystitis/bladder pain syndrome (IC/BPS) are lacking. We investigated the treatment outcome in IC/BPS patients receiving intravesical BoNT-A injections. This retrospective study included IC/BPS patients who had 100U BoNT-A intravesical injections in the past 20 years. The treatment outcomes at 6 months following the BoNT-A treatment were evaluated using the global response assessment (GRA) scale. The treatment outcomes according to the GRA scale include clinical symptoms, urodynamic parameters, cystoscopic characteristics, and urinary biomarkers, and it was these predictive factors for achieving satisfactory outcomes which were investigated. Among the 220 enrolled patients (180 women, 40 men) receiving BoNT-A injections, only 87 (40%) had significantly satisfactory treatment outcomes. The satisfactory group showed significantly larger voided volumes, and lower levels of both the urinary inflammatory protein MCP-1 and the oxidative stress biomarker 8-isoprostane in comparison to the unsatisfactory group. The IC severity and detrusor pressure are predictive factors of BoNT-A treatment outcomes. IC/BPS patients with less bladder inflammation showed satisfactory outcomes with intravesical BoNT-A injections. Patients with severe bladder inflammation might require more intravesical BoNT-A injections to achieve a satisfactory outcome.

Abstract
BACKGROUND Urinary tract infections are among the most common indications for antibiotic therapy. The emergence of resistant uropathogens indicates the need for treatment alternatives. Replenishment of the glycosaminoglycan layer of the bladder, achieved by intravesical instillation of e.g. chondroitin sulphate (CS), is described to be a cornerstone in the therapy of cystitis. To retrospectively evaluate the efficacy of a therapy with 0.2% CS in patients suffering recurrent urinary tract infections (rUTI) in comparison to a treatment with low-dose long-term antibiotics (LDLTAB) and a combination of both. METHODS A total of 151 patients with recurrent UTI who underwent intravesical therapy at Diaconesse hospital in Leiden, The Netherlands were included. 50 patients had been treated with CS, 51 patients had received LDLTAB, and 50 patients had received a combination therapy (LDLTABCS). Data recorded for baseline, after 6, and 12 months of treatment were evaluated. Descriptive statistics were calculated. Exploratory comparisons between groups and within groups were performed by using one-tailed and paired t-tests. Patients filled in a standardized quality of life questionnaire (EQ-5D). RESULTS We found a statistically significant reduction of number of infections from 7.10 ± 0.50 SEM to 0.45 ± 0.07 SEM after 12 months therapy with CS compared to 12 months therapy with LDLTAB (from 7.04 ± 0.47 SEM to 1.8 ± 0.15 SEM). The number of visits to the urologist significantly decreased in the CS group from 7.46 ± 0.80 SEM to 1.28 ± 0.11 SEM and from 4.10 ± 0.29 SEM to 1.35 ± 0.11 SEM in the LDLTABCS group. In addition, a significant increase in Quality of life (QoL) was seen in the CS-group (from 58.2 ± 0.82 SEM to 80.43 ± 0.82 SEM) and in the LDLTABCS group (from 62.4 ± 0.97 SEM to 76.73 ± 1.06 SEM). There was no improvement in QoL with LDLTAB (from 58.24 ± 1.08 SEM to 58.96 ± 1.19 SEM). Evaluation's evidence is limited due to its retrospective character. CONCLUSIONS Retrospective analysis of data from patients that underwent therapy for rUTIs confirms the safety and efficacy of CS and indicate a superiority to antibiotic treatment of rUTIs.

Abstract
Chronic primary pelvic pain syndrome (CPPPS) is a heterogeneous disease with unknown pathogenesis and a lack of distinct pathological features, which complicates diagnosis and therapy and has a significant impact on patients' daily life. Because pharmacological management is ineffective and long-term use may result in additional system damage, developing a more effective treatment is critical. Neuromodulation has advanced rapidly over the last few decades, and various types of neuromodulations have demonstrated efficacy in the treatment of CPPPS. In this article we discuss the evolution of neuromodulation technology in the treatment of chronic pelvic pain, its application to various subtypes of chronic pelvic pain, and the comparison of relevant efficacy and parameter differences, as well as assess the relative advantages and disadvantages of sacral neuromodulation, percutaneous tibial nerve stimulation , transcutaneous electrical nerve stimulation, electroacupuncture, and pudendal neuromodulation. Furthermore, it was noted that chronic pelvic pain should be evaluated in terms of pain, associated symptoms, psychological problems, and quality of life. Although neuromodulation approaches have been shown to be effective in treating chronic pelvic pain, more extensive multicenter trials are required to confirm this.

Abstract
The assessment and management of urologic chronic pelvic pain syndrome (UCPPS), is controversial. It is classified by voiding symptoms, pelvic pain, and bladder pain, which is weekly treated, weekly understood, and bothersome. In the aspect of clinical efforts and research to help people with this syndrome have been hampered by the deficiency of a widely reliable, accepted, and a valuable tool to evaluate the patient symptoms and quality of life (QoL) impact. However, the etiology comes into sight is multifactorial, and available treatment options have been imprecise considerably in present years. We compiled the published literature on the assessment of the syndrome, a tentative role of pharmacological and non-pharmacological (conservative, alternative, and invasive therapy) interventions in eradicating the disease as well as improving symptoms. The previously published literature on animal models has established the association of immune systems in the etiology, pathogenesis, and progression of the disease. The UPOINT system for clinical phenotyping of UCPPS patients has six predefined domains that direct multimodal therapy, which would lead to significant symptom improvement in the medical field. The narrative review aims to scrutinize the fluctuating scientist's views on the evaluation of patient and multimodal treatment of the UPOINT system.

[PMID: 35054241 PMCID: PMC8774507 DOI: 10.3390/diagnostics12010075] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Revised: 12/18/2021] [Accepted: 12/20/2021] [Indexed: 12/25/2022] Open
Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is defined as a chronic bladder disorder with suprapubic pain (pelvic pain) and pressure and/or discomfort related to bladder filling accompanied by lower urinary tract symptoms, such as urinary frequency and urgency without urinary tract infection (UTI) lasting for at least 6 weeks. IC/BPS presents significant bladder pain and frequency urgency symptoms with unknown etiology, and it is without a widely accepted standard in diagnosis. Patients’ pathological features through cystoscopy and histologic features of bladder biopsy determine the presence or absence of Hunner lesions. IC/PBS is categorized into Hunner (ulcerative) type IC/BPS (HIC/BPS) or non-Hunner (nonulcerative) type IC/BPS (NHIC/BPS). The pathophysiology of IC/BPS is composed of multiple possible factors, such as chronic inflammation, autoimmune disorders, neurogenic hyperactivity, urothelial defects, abnormal angiogenesis, oxidative stress, and exogenous urine substances, which play a crucial role in the pathophysiology of IC/BPS. Abnormal expressions of several urine and serum specimens, including growth factor, methylhistamine, glycoprotein, chemokine and cytokines, might be useful as biomarkers for IC/BPS diagnosis. Further studies to identify the key molecules in IC/BPS will help to improve the efficacy of treatment and identify biomarkers of the disease. In this review, we discuss the potential medical therapy and assessment of therapeutic outcome with urinary biomarkers for IC/BPS.

[PMID: 34943535 PMCID: PMC8700450 DOI: 10.3390/diagnostics11122298] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 12/03/2021] [Accepted: 12/03/2021] [Indexed: 11/29/2022] Open
Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic, often incapacitating condition characterized by pain seeming to originate in the bladder in conjunction with lower urinary tract symptoms of frequency and urgency, and consists of a wide range of clinical phenotypes with diverse etiologies. There are currently no diagnostic tests for IC/BPS. Magnetic resonance imaging (MRI) is a relatively new tool to assess IC/BPS. There are several methodologies that can be applied to assess either bladder wall or brain-associated alterations in tissue morphology and/or pain. IC/BPS is commonly associated with bladder wall hyperpermeability (BWH), particularly in severe cases. Our group developed a contrast-enhanced magnetic resonance imaging (CE-MRI) approach to assess BWH in preclinical models for IC/BPS, as well as for a pilot study for IC/BPS patients. We have also used the CE-MRI approach to assess possible therapies to alleviate the BWH in preclinical models for IC/BPS, which will hopefully pave the way for future clinical trials. In addition, we have used molecular-targeted MRI (mt-MRI) to quantitatively assess BWH biomarkers. Biomarkers, such as claudin-2, may be important to assess and determine the severity of BWH, as well as to assess therapeutic efficacy. Others have also used other MRI approaches to assess the bladder wall structural alterations with diffusion-weighted imaging (DWI), by measuring changes in the apparent diffusion coefficient (ADC), diffusion tensor imaging (DTI), as well as using functional MRI (fMRI) to assess pain and morphological MRI or DWI to assess anatomical or structural changes in the brains of patients with IC/BPS. It would be beneficial if MRI-based diagnostic tests could be routinely used for these patients and possibly used to assess potential therapeutics.

β-Defensin 2, an Antimicrobial Peptide, as a Novel Biomarker for Ulcerative Interstitial Cystitis; Can β-Defensin 2 Suspect the Dysbiosis of Urine Microbiota? Diagnostics (Basel) 2021; 11:diagnostics11112082. [PMID: 34829429 PMCID: PMC8619152 DOI: 10.3390/diagnostics11112082] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Revised: 11/06/2021] [Accepted: 11/09/2021] [Indexed: 12/21/2022] Open
Abstract
As urine is not sterile, inflammatory reactions caused by dysbiosis of the urinary microbiota may induce interstitial cystitis. A study was conducted to determine whether β-defensin 2 (BD-2), a specific antimicrobial peptide in the bladder, could be used as a novel diagnostic marker for ulcerative interstitial cystitis (IC). Urine samples from three female groups were examined: healthy controls (n = 34, Control group), non-Hunner type IC (n = 40, NHIC group), and Hunner type IC (n = 68, HIC group). Urine samples were collected via a transurethral catheter and assayed for BD-2 levels using enzyme linked immunosorbent assay. Under general or regional anesthesia, cystoscopy with diagnostic and therapeutic hydrodistension was performed in NHIC and HIC groups patients. These patients underwent a biopsy of the bladders. Based on the urinary specimens from 142 patients, BD-2 expression was found to be 18-fold higher in patients with Hunner type IC than in patients with non-Hunner type IC. The enhanced secretion of BD-2 exhibited a strong correlation with increased mast cell counts associated with bladder IC pathology. Enhanced urinary secretion of the antimicrobial peptide BD-2 from Hunner type IC patients associated with clinical phenotypes and demonstrated relatively robust levels to be used as a potential biomarker. Moreover, the increased urinary level of BD-2 may suggest a new possibility of biomarkers caused by dysbiosis of the urinary microbiota in ulcerative IC.

Abstract
Background Glomerulations are not specific for interstitial cystitis/bladder pain syndrome (IC/BPS). Controversy exists about whether cystoscopic findings differ between patients with and without lower urinary tract symptoms. We sought to compare the prevalence of cystoscopic findings in women with “no or minimal” urinary symptoms to those with a “high” symptom burden. Methods This is a secondary analysis of a prospective cohort study performed at a University Educational Facility. Participants in this study were part of a larger prospective study, in which female patients scheduled to undergo routine gynecologic procedures were all consented for cystoscopy with hydrodistension (CWHD). We defined the “minimally symptomatic group” as those with ≤1 on each of the O’Leary/Sant Interstitial Cystitis Symptom Index (ICSI) subscores and without history of IC/BPS. The “highly symptomatic” cohort of women had composite ICSI score ≥12 and a Burning/Pain subscore of 4 or 5. All were non-smokers. Results A total of 84 women underwent CWHD, with 33 having minimal symptoms and 51 being highly symptomatic. The two groups were not statistically different when assessing for ‘any glomerulations’ compared to ‘no glomerulations.’ However, minimally symptomatic women had an eight-fold lower prevalence of significant glomerulations than highly symptomatic women (3.0% minimally symptomatic vs. 23.5% highly symptomatic, P<0.05.) Conclusions Extensive glomerulations (≥10 in 3 or 4 quadrants) are rare in women with minimal urinary symptoms. These findings contrast with prior limited prospective data which quoted similar incidence of glomerulations in IC/BPS patients and asymptomatic patients. This study highlights the importance of evaluating objective evidence on CWHD and merits further investigation as part of the ongoing conversation regarding the definition of bladder health and pathology

Abstract
OBJECTIVE To compare the clinical presentation of UCPPS from a large clinical practice grouped by their presenting age to improve the evaluation of this condition. METHODS A total of 223 male and female patients seeking care for their UCPPS were recruited to study their urologic and non-urologic presentation. Their evaluation included cystoscopy and multiple questionnaires to assess their pelvic pain, non-urologic pain, urinary symptoms, somatic symptoms, and psychosocial health. Patients were then grouped by age into the following groups: less than 30 years of age, between the ages of 30 and 60, and older than 60. These groups were then compared on multiple domains. RESULTS Patients between the ages of 60 and 30 were most likely to have concomitant COPC (such as fibromyalgia or migraine headaches), more widespread distribution of non-urologic pain, higher somatic symptom burden, and depression. Patients 30 years old or younger were more likely to have more severe urologic and non-urologic pain, and urinary pain symptoms that are less typical of IC/BPS (eg, pain worsened during or after urination). Patients older than 60 were more likely to have Hunner lesion (55.6% vs 23.8% vs 8.6% among those who had cystoscopy, in decreasing age, P < .001). CONCLUSION Our findings support the evaluation of non-urologic pain, COPC and psychosocial health in middle-aged patients; Hunner lesion in older patients; and a higher clinical suspicion of other confusable diagnoses when younger patients present with atypical symptoms.

Identification of key genes in human urothelial cells corresponding to interstitial cystitis/bladder pain syndrome in a lipopolysaccharide-induced cystitis model. Neurourol Urodyn 2021; 40:1720-1729. [PMID: 34245600 DOI: 10.1002/nau.24743] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Revised: 06/18/2021] [Accepted: 06/22/2021] [Indexed: 02/05/2023]
Abstract
AIMS The cellular functions of bladder urothelial cells in interstitial cystitis/bladder pain syndrome (IC/BPS) have not been well revealed and understood. Thus, the study aims to identify key genes and significant pathways in urothelium corresponding to IC/BPS in a lipopolysaccharide (LPS)-induced cystitis model and provide novel clues related to diagnosis and treatment of IC/BPS. METHODS Human urothelial cells (HUCs) were incubated with LPS (50 μg/ml for 24 h). Microarray was applied to analyze the differentially expressed genes (DEGs) between HUCs under LPS treatment and the control group. DEGs in the two groups were identified and then used for enrichment analysis. Subsequently, protein-protein interaction (PPI) network based on DEGs was constructed. Lastly, the top five key genes were identified through the Cytoscape (version 3.7.2) using the "Clustering Coefficient" algorithm. RESULTS One hundred and seventy-one DEGs (96 upregulated genes and 75 downregulated genes) were identified between the LPS treatment and control group. The established PPI network was composed of 169 nodes and 678 edges. Moreover, C19orf33, TRIM31, MUC21, ELF3, and IFI27 were identified as hub genes in the PPI network. Subsequently, a statistically increased expression level of TRIM31 and ELF3 was validated by real-time quantitative-polymerase chain reaction and immunohistochemistry in bladder tissues from 20 patients with IC/BPS. CONCLUSIONS TRIM31 and ELF3 may be the two hub genes in urothelium corresponding to IC/BPS. More studies are warranted to further validate the findings. The identified marker genes may be useful targets for further studies to develop diagnostic tools and more effective therapies for a broader group of women with IC/PBS.

Abstract
INTRODUCTION AND HYPOTHESIS The objective was to compare the clinical efficacy and safety of pharmacological interventions for interstitial cystitis and bladder pain syndrome (IC/BPS) with direct and indirect evidence from randomized trials. METHODS We searched PubMed, the Cochrane library, and EMBASE for randomized controlled trials (RCTs) that assessed the pharmacological therapies for IC/BPS. Primary efficacy outcomes included ICSI (O'Leary Sant Interstitial Cystitis Symptom Index), ICPI (O'Leary Sant Interstitial Cystitis Problem Index), 24-h micturition frequency, visual analog scale (VAS), and Likert score for pain. Safety outcomes are total adverse events (AEs, intravesical instillation, and others), gastrointestinal symptoms, headache, pain, and urinary symptoms. A systematic review and Bayesian network meta-analysis were performed. RESULTS A total of 23 RCTs with 1,871 participants were identified. The ICSI was significantly reduced in the amitriptyline group (MD = -4.9, 95% CI: -9.0 to -0.76), the cyclosporine A group (MD = -7.9, 95% CI: -13.0 to -3.0) and the certolizumab pegol group (MD = -3.6, 95% CI:-6.5 to -0.63) compared with placebo group. Moreover, for ICPI, cyclosporine A showed superior benefit compared to placebo (MD = -7.6, 95% CI: -13 to -2.3). VAS score improved significantly in cyclosporine A group than pentosan polysulfate sodium (MD = 3.09, 95% CI: 0.13 to 6.07). None of the agents revealed a significant alleviation of 24-h micturition frequency. In terms of safety outcomes, the incidence rate on urinary symptoms for botulinum toxin A was the only variate higher than chondroitin sulfate (MD = -2.02, 95% CI: -4.99 to 0.66) and placebo (MD = -1.60, 95% CI:-3.83 to 0.17). No significant difference was found among the other treatments. CONCLUSIONS Cyclosporine A might be superior to other pharmacological treatments in efficacy. Amitriptyline and certolizumab pegol were capable of lowering the ICSI as well.

Abstract
INTRODUCTION AND HYPOTHESIS The aim of this study was to compare the frequency of metabolic syndrome (MetS) in patients with and without interstitial cystitis/bladder pain syndrome (IC/BPS). METHODS This case-control study evaluated the indicators of MetS in 287 females with IC/BPS and in 287 females without IC/BPS in West China Hospital between January 2010 and January 2020. Then, the number of voids per day, frequency of night urination, O'Leary-Sant Interstitial Cystitis Symptom/Problem Index, and visual analog scale were examined in the two groups. RESULTS Based on both the National Cholesterol Education Program Adult Treatment Panel III recommendations and the International Diabetes Federation criteria, the distribution of MetS was statistically higher in patients with IC/BPS than in the control group, with 34.8% vs 17.8% (P < 0.0001) and 34.2% vs 20.9% (P = 0.0005), respectively. Regarding symptom scores, the IC/BPS group demonstrated significantly higher scores than the control group in all aspects (P < 0.0001). More patients with anxiety (P < 0.0001), insomnia (P < 0.0001), hypertension (P = 0.0001), and diabetes mellitus (P = 0.017) were observed in the IC/BPS group. Moreover, the findings indicated that patients with IC/BPS had a higher BMI (P = 0.0001) and larger waist circumference (P = 0.0001). Blood tests presented a significantly higher level of fasting glycemia, serum cystatin-C, and triglycerides in patients with IC/BPS. Furthermore, higher ORs for the occurrence of MetS among cases were observed, although this was not statistically significant. CONCLUSIONS MetS frequency was relatively high in patients with IC/BPS. Further research is needed to understand the common pathophysiologic mechanism of IC/BPS and MetS.

Abstract
OBJECTIVE: Interstitial cystitis/bladder pain syndrome (IC/BPS) refers to diseases that are challenging to identify, diagnose and treat. Thus, there is a need to study the clinical and cystoscopic picture of IC/BPS. The present research aims to study the clinical manifestations and results of cystoscopy with hydrodistension in women with IC/BPS. METHODS: One hundred twenty-six women with clinically diagnosed IC/BPS were examined – their mean age was 46.7±14.0 years. Patients were surveyed on pelvic pain and urgency/frequency patient symptom score (PUF), visual analogue scale (VAS) and urgency severity scale (USS). All patients underwent a potassium test (PST) and cystoscopy with hydrodistension. Statistical analysis was performed using SPSS software version 15.0 (SPSS Inc., Chicago, Illinois, USA). RESULTS: The average PUF score was 8.14±1.76 points, VAS – 5.45±0.93 points and USS – 2.63±0.91 points. A positive potassium test was detected in 91.3% of cases. The maximum average anatomical capacity of the bladder was 308.0±77.5 ml. The maximal cystometric capacity in women with mild pain was higher than among women with moderate and severe pain by 30.9% (p<0.05) and 53.0% (p<0.01), respectively. In most cases, mucosal changes were diffuse (n=57) or located in two parts of the bladder. One of the most common symptoms was the diffuse bleeding of the bladder mucosa (III degree). A statistically significant inverse correlation (r=-0.57, p<0.01) was found between the maximal cystometric bladder volume and the severity of the bladder mucosa changes. At the same time, a positive correlation was found between the severity of the bladder mucosa changes and the sum of points on the PUF questionnaire (r=+0.61, p=0.0003), the sum of points on the VAS questionnaire (r=+0.59, p=0.0008) and the USS questionnaire (r=+0.66, p=0.005). CONCLUSION: A relationship has been established between the clinical manifestations of IC/BPS among examined women and changes in the wall of the bladder. The data obtained from our investigation can help increase IC/BPS diagnostics and improve IC/BPS treatment results.

Abstract
BACKGROUND Bladder pain syndrome (BPS), which includes the condition of interstitial cystitis, is a poorly understood clinical condition for which patients present with varying symptoms. Management of BPS is challenging for both patients and practitioners. At present, there is no universally accepted diagnosis and diverse causes have been proposed. This is reflected in wide-ranging treatment options, used alone or in combination, with limited evidence. A network meta-analysis (NMA) simultaneously comparing multiple treatments may help to determine the best treatment options for patients with BPS. OBJECTIVES To conduct a network meta-analysis to assess the effects of interventions for treating people with symptoms of bladder pain syndrome (BPS). SEARCH METHODS We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL, in the Cochrane Library), MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, ClinicalTrials.gov, the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) and handsearched journals and conference proceedings (searched 11 May 2018) and the reference lists of relevant articles. We conducted a further search on 5 June 2019, which yielded four small studies that were screened for eligibility but were not incorporated into the review. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs of interventions for treating adults with BPS. All types of interventions (including conservative, pharmacological and surgical) were eligible. DATA COLLECTION AND ANALYSIS We assessed the risk of bias of included studies using Cochrane's 'Risk of bias' tool. Primary outcomes were the number of people cured or improved, pain, frequency and nocturia. For each outcome, random-effects NMA models were fitted using WinBUGS 1.4. We monitored median odds ratios (ORs) for binary outcomes and mean differences (MDs) for continuous outcomes with 95% credible intervals (Crls). We compared results of the NMA with direct evidence from pairwise meta-analysis of head-to-head trials. We used the CINeMA tool to assess the certainty of evidence for selected treatment categories. MAIN RESULTS We included 81 RCTs involving 4674 people with a median of 38 participants (range 10 to 369) per RCT. Most trials compared treatment against control; few trials compared two active treatments. There were 65 different active treatments, and some comparisons were informed by direct evidence from only one trial. To simplify, treatments were grouped into 31 treatment categories by mode of action. Most studies were judged to have unclear or high risk of bias for most domains, particularly for selection and detection bias. Overall, the NMA suggested that six (proportion cured/improved), one (pain), one (frequency) and zero (nocturia) treatment categories were effective compared with control, but there was great uncertainty around estimates of effect. Due to the large number of intervention comparisons in this review, we focus on three interventions: antidepressants, pentosan polysulfate (PPS) and neuromuscular blockade. We selected these interventions on the basis that they are given 'strong recommendations' in the EAU Guidelines for management of BPS (EAU Guidelines 2019). We found very low-certainty evidence suggesting that antidepressants were associated with greater likelihood of cure or improvement compared with control (OR 5.91, 95% CrI 1.12 to 37.56), but it was uncertain whether they reduced pain (MD -1.27, 95% CrI -3.25 to 0.71; low-certainty evidence), daytime frequency (MD -2.41, 95% CrI -6.85 to 2.05; very low-certainty evidence) or nocturia (MD 0.01, 95% CrI -2.53 to 2.50; very low-certainty evidence). There was no evidence that PPS had improved cure/improvement rates (OR 0.14, 95% CrI 0.40 to 3.35; very low-certainty evidence) or reduced pain (MD 0.42, 95% CrI -1.04 to 1.91; low-certainty evidence), frequency (MD -0.37, 95% CrI -5.00 to 3.44; very low-certainty evidence) or nocturia (MD -1.20, 95% CrI -3.62 to 1.28; very low-certainty evidence). There was evidence that neuromuscular blockade resulted in greater cure or improvement (OR 5.80, 95% CrI 2.08 to 18.30) but no evidence that it improved pain (MD -0.33, 95% CrI -1.71 to 1.03), frequency (MD -0.91, 95% CrI -3.24, 1.29) or nocturia (MD -0.04, 95% CrI -1.35 to 1.27). The certainty of this evidence was always very low. AUTHORS' CONCLUSIONS We are uncertain whether some treatments may be effective in treating patients with BPS because the certainty of evidence was generally low or very low. Data were available for a relatively large number of trials, but most had small sample sizes and effects of treatments often could not be estimated with precision. An NMA was successfully conducted, but limited numbers of small trials for each treatment category hampered our ability to fully exploit the advantages of this analysis. Larger, more focused trials are needed to improve the current evidence base.

Abstract
A botulinum toxin A (BoNT-A) intravesical injection can improve the symptoms of interstitial cystitis/bladder pain syndrome (IC/BPS). Patients with IC/BPS have different clinical characteristics, urodynamic features, and cystoscopic findings. This study assessed the treatment outcomes of a BoNT-A intravesical injection and aimed to identify the predictive factors of a satisfactory outcome. This retrospective study included IC/BPS patients treated with 100 U BoNT-A. The treatment outcomes were assessed by global response assessment (GRA) at 6 months. We classified patients according to different clinical, urodynamic, and cystoscopic characteristics and evaluated the treatment outcomes and predictive factors. A total of 238 patients were included. Among these patients, 113 (47.5%) had a satisfactory outcome (GRA ≥ 2) and 125 (52.5%) had an unsatisfactory outcome. Improvements in the IC symptom score, IC problem score, O'Leary-Sant symptom score, and visual analog scale score for pain were significantly greater in patients with a satisfactory outcome than in patients with an unsatisfactory outcome (all p = 0.000). The IC disease duration and maximal bladder capacity (MBC) were significantly different between patients with and without a satisfactory outcome. Multivariate analysis revealed that only the MBC was a predictor for a satisfactory outcome. Patients with a MBC of ≥760 mL and glomerulations of 0/1 (58.7%) or glomerulations of 2/3 (75.0%) frequently had a satisfactory outcome. We found that BoNT-A intravesical injection can effectively improve symptoms among patients with IC/BPS, with a remarkable reduction in bladder pain. A MBC of ≥760 mL is a predictive factor for a satisfactory treatment outcome.

Abstract
INTRODUCTION AND HYPOTHESIS Bladder pain syndrome (BPS) is a disease of unknown etiology defined as an unpleasant sensation related to the bladder, associated with lower urinary tract symptoms of more than 6 weeks' duration, in the absence of any identifiable causes. Despite its impact on quality of life (QoL) and socioeconomic burden, there are no objective methods for the diagnosis or assessment of therapeutic response. We systematically reviewed biomarkers associated with BPS to update the current knowledge on this issue. METHODS A systematic review of the Cochrane Library, Embase, PubMed/MEDLINE, LILACS, SCOPUS, and ClinicalTrials.gov databases was conducted following the PRISMA statement. Original articles investigating biomarkers for the diagnosis or symptom assessment of patients with BPS were assessed; no language restrictions were applied. Animal or post-mortem studies were excluded. RESULTS Of the 478 records retrieved, 11 articles were included. MIF, NGF, Etio-S, APF, and a combined methylhistamine/Il-6 model were increased in BPS urine samples versus controls. Also increased were glyceraldehyde in stool, in addition to the expression of some genes (ARID1A, ARF, CHAT, eNOS, GLI-1, iNOS, MCP-1, NGF, WNT-8A, WNT-10A), nerve density, IL-16, VCAM-1, and ICAM-1 in bladder tissue specimens. In contrast, some fecal bacteria, expression of other genes (CHT, HB-EGF, OCT-1, SMRT-1, WNT11) in the bladder urothelium, and urinary DNA methylation in CpG-sites, MCP-3, G5P1, and HB-EGF were decreased in BPS. As none of the biomarkers was studied more than once, a Forest plot could not be constructed. Only 4 articles reported the relation of biomarkers to symptom scores. CONCLUSIONS Potential biomarkers for BPS in urine, stool, and bladder biopsy specimens are described. Further research is needed before their use in clinical practice.

Abstract
AIMS The complexity of Interstitial Cystitis/bladder Pain Syndrome (IC/BPS) has led to a great deal of uncertainty around the diagnosis and prevalence of the condition. Under the hypothesis that IC/BPS is frequently misdiagnosed, we sought to assess the accuracy of the ICD-9/ICD-10 code for IC/BPS using a national data set. METHODS Using the Veterans Affairs Informatics and Computing Infrastructure, we identified a random sample of 100 patients with an ICD-9/ICD-10 diagnosis of IC/BPS (595.1/N30.10) by querying all living patients in the Veterans Affairs (VA) system. We purposely sampled men and women equally to better understand gender-specific practice patterns. Patients were considered a correct IC/BPS diagnosis if they had two visits complaining of bladder-centric pain in the absence of positive urine culture at least 6 weeks apart. Patients were considered not to have IC/BPS if they had a history of pelvic radiation, systemic chemotherapy, metastatic cancer, or bladder cancer. RESULTS Of the 100 patients, 48 were female and 52 were male. Five had prior radiation, one had active cancer, and 10 had bladder cancer (all male), and an additional fifteen had insufficient records. Of the remaining 69 patients, 43% did not have IC/BPS. Of these patients who did not have IC/BPS, 43% complained only of overactive bladder (OAB) symptoms, which was more common in women (63%) than men (21%), P = .003. CONCLUSIONS In our small sample from a nationwide VA system, results indicate that IC/BPS has a high misdiagnosis rate. These findings shed light on the gender-specific diagnostic complexity of IC/BPS.

Abstract
INTRODUCTION AND HYPOTHESIS Interstitial cystitis (IC) and bladder pain syndrome (BPS) are challenging and encompassing hypersensitivity disorders of the lower urinary tract. A variety of national and international guidelines have been published including guidance on nomenclature, definitions, etiopathology, diagnostics and treatment. A lack of universally established clinical guidance is apparent. The aim of this review is to evaluate key guidelines on this area of practice, identify variations, compare their recommendations and grade them using AGREE II. METHODS Literature searches were performed using the PUBMED and CINAHL database from January 1, 1983, to December 1, 2018, referring to the search strategy of AUA. Ten national and international guidelines were included into the analysis. We assessed the guidelines with the updated AGREE II. RESULTS Symptoms congruent in all guidelines are: pain, pressure, discomfort and frequency, urgency and nocturia. Urinalysis is a prerequisite for diagnostics, cystoscopy for most and urodynamics not part of the routine assessment. Treatment options are recommended stepwise. The highest level of evidence and consensus was identified for oral therapies. Nine guidelines had an overall quality score ≥ 50% and three scored ≥ 70% (AUA, GG, RCOG). CONCLUSIONS The guidelines are congruent in symptom reporting, quite congruent in diagnostics and vary to a high degree on treatment recommendations. The complexity of BPS and emerging evidence indicate the need for regular updating of the guidelines and a wider consensus.

Abstract
INTRODUCTION Interstitial Cystitis (IC) is a chronic condition diagnosed based on the presence of symptoms, such as suprapubic/ pelvic pain, pressure or discomfort in association with urgency and increased urinary frequency. Confusable diseases must be excluded. However, there is no objective test or marker to establish the presence of the disease. Diagnosis and patient management is often difficult, given the poor understanding of IC pathogenesis and its unknown etiology and genetics. As an attempt to find biomarkers related to IC, we assessed the association between 20 selected single nucleotide polymorphism (SNPs) with IC and pain severity. OBJECTIVES To assess the presence of SNPs in IC patients' blood samples and correlate them with the disease and chronic pain condition. METHODS A case-control study was conducted. We selected 34 female patients with IC diagnosed according to NIDDK criteria and 23 patients in the control group (previously healthy women with only stress urinary incontinence). IC patients were allocated into two groups according to reported chronic pain severity. We selected the following SNPs for analysis: rs1800871, rs1800872, rs1800896, rs1800471, rs1800629, rs361525, rs1800497, rs6311, rs6277, rs6276, rs6313, rs2835859, rs11127292, rs2243248, rs6887695, rs3212227, rs1799971, rs12579350, rs3813034, and rs6746030. Genotyping was performed by real-time PCR (q-PCR). RESULTS The polymorphic allele of SNP rs11127292 exhibited a higher frequency in subjects with IC than in controls (p:0.01). The polymorphic allele of SNP rs6311 was more frequent in patients with severe pain (p:0.03). The frequency of the wild-type allele of SNP rs1799971 was higher in patients with mild to moderate pain (p:0.04). CONCLUSION The results indicated differences in SNP frequency among subjects, suggesting that SNPs could serve either as a marker of IC or as a marker of pain severity in IC patients. The study showed promising results regarding IC and polymorphism associations. These associations have not been previously reported.

Abstract
Objective: In the present study, we investigated the efficacy of bladder hydrodistension combined with pentosan polysulfate (PPS) treatment in interstitial cystitis (IC)/bladder pain syndrome (BPS). Methods: In this study, 339 patients diagnosed with IC/BPS were categorized into two groups. The first group only received 300 mg/day PPS, while the second group received 300 mg/day PPS following bladder hydrodistension. The results were evaluated at the 3rd, 6th, and 12th months after the first dose using the interstitial cystitis symptom index (ICSI), international cystitis problem index (ICPI), visual analog scale (VAS), and female sexual function index (FSFI). Results: PPS treatment started just after hydrodistension was significantly more effective than PPS treatment alone and combined treatment significantly reduced the rate of non-compliance such that, at the end of the 3rd month, 12.1% patients in Group-1 did not continue their treatment whereas only 1.9% of patients in Group-2 did not continue. Conclusions: The study results indicate that PPS treatment started just after hydrodistension yields significantly better results in terms of both symptom improvement and treatment compliance in patients with IC/BPS.

Abstract
Herein, we aimed to review, report, and discuss the role of cystoscopy and clinical phenotyping in interstitial cystitis/bladder pain syndrome (IC/BPS). For this purpose; a comprehensive nonsystematic review of the relevant literature was conducted. We reviewed articles published in English and indexed in the PubMed, Embase, and Google Scholar databases. Original manuscripts, review articles, case series, and case reports were taken into consideration. Data regarding the indications for, technique, and possible findings of cystoscopy with hydrodistension (HD) and biopsy, as well as clinical implications of cystoscopic information and the concept and use of clinical phenotyping within the context of IC/ BPS were extracted and discussed. IC/BPS is diagnosed based on symptomatic assessment and exclusion of confusable diseases. There is no universal agreement upon the evaluation and diagnostic algorithm of IC/BPS. The majority of the guidelines recommend cystoscopy with HD and biopsy as a diagnostic prerequisite. Various different techniques have been described for cystoscopy with HD. General or epidural anesthesia is more commonly preferred and advocated while assessing endoscopic alterations in patients suspected of having IC/BPS. Cystoscopy with HD and biopsy enables more objective exclusion of confusable diseases. It also provides the basis of the European Society for the Study of Interstitial Cystitis classification. Patients with IC/BPS who demonstrate positive cystoscopic (glomerulations and/or Hunner lesion) and histologic findings have a more severe symptomatology and may benefit from lesion-targeted endoscopic treatments. Clinical phenotyping has been implemented for IC/BPS and may be used for individualized assessment and treatment.

Abstract
INTRODUCTION AND HYPOTHESIS This aim of this study was to better understand ulcerative interstitial cystitis/painful bladder syndrome (IC/PBS) at the molecular level and provide new clues related to diagnosis and treatment. METHODS The microarray data set GSE11783, including the mRNA and miRNA profiles of bladder tissue obtained at cystoscopic biopsy from patients with ulcerative IC/PBS (presence of at least one Hunner's ulcer) and normal controls, was downloaded from the GEO (Gene Expression Omnibus) database (National Center for Biotechnology Information). These were evaluated using Greenspring GX and Ingenuity Pathway Analysis (IPA) software. The differentially expressed genes (DEGs) and miRNAs (DEMs) in these two groups were identified. Subsequently, the DEGs were subjected to functional analysis, and a protein-protein interaction (PPI) network was constructed. Finally, the miRNA-mRNA regulatory network was visualized using Cystoscope software. RESULTS Four DEMs and 1521 DEGs were identified between the ulcerative IC/PBS and control groups. The PPI network of the DEGs was constructed by STRING, which was composed of 393 nodes and 1039 edges, including 221 upregulated genes and 172 downregulated genes. Moreover, 27 genes in the PPI network were identified as hub genes in the IC/PBS group, e.g., PNOC, SSTR1, FPR3, GPR18 and APLNR. Subsequently, 27 clusters were selected from the PPI network using MCODE. It was shown that the most significant cluster consisted of 22 nodes and 231 edges. Moreover, miR-21 was the most significantly upregulated miRNA and was predicted to target one upregulated gene (RASGRP1) and two downregulated genes (KLF5 and SC5D). CONCLUSIONS The results of this data mining and integration provide further information on the possible molecular basis of IC/PBS pathogenesis as well as potential biomarkers and therapeutic targets for ulcerative IC/PBS diagnosis and treatment.

Abstract
OBJECTIVES Bladder pain syndrome (BPS) is a debilitating condition which can be difficult to diagnose and treat due to the lack of consensus on aetiology, definition, and management. The aim of this review is to summarise the findings from major national and international guidelines on the management of BPS, highlighting areas of disagreement and uncertainty. METHODS We performed a Medline/PubMed search from 1st January 2000 to 31st December 2017 in order to identify relevant guidelines addressing BPS/interstitial cystitis. We also manually searched the websites of major national and international societies. The following guidelines were included in this review: European Association of Urology, American Urological Association, International Society for the Study of BPS, International Consultation on Incontinence, International Continence Society, East Asian guideline, Royal College of Obstetricians and Gynaecologists/British Society of Urogynaecology, and the Canadian Urological Association. RESULTS There is disagreement between guidelines on the exact definition of BPS and the nomenclature to use to describe this condition. However, all agree that the diagnosis is dependent on the presence of pain, pressure, or discomfort, in addition to at least one urinary symptom, in the absence of other diseases that could cause pain. Exclusion of other pathology that could cause similar symptoms requires thorough evaluation, and is recommended in all guidelines. There is also disparity in the recommended diagnostic investigation of BPS, with hydrodistension and bladder biopsy either recommended, considered optional, or not recommended, by different guidelines. It is accepted that BPS can be diagnosed clinically, without invasive investigation, but cystoscopy and diagnostic hydrodistension aids sub-typing of patients and may help direct treatment strategies. Patients should be phenotyped in order to direct multimodal treatment (including behavioural, physical, emotional, and psychological therapy), and treatments should follow a stepwise approach starting with the most conservative. Although widely performed, hydrodistension as a therapeutic strategy has a limited evidence base and is unlikely to provide long-term resolution of symptoms CONCLUSION: There are multiple national and international guidelines for the diagnosis and management of BPS, and this review has highlighted the differences in nomenclature, definitions, and recommended diagnostic tests between guidelines. The overall evidence base for the majority of treatments for BPS/IC is of low-quality, and larger randomised trials are required to more accurately inform guideline recommendations and clinical management of this complex group of patients.

Abstract
INTRODUCTION Interstitial cystitis/bladder pain syndrome (IC/BPS) patients represent a heterogeneous group with pain and urinary storage symptoms and varying responses to current treatment options. The novel beta-3 agonist, mirabegron, has been shown to improve storage symptoms of patients with bladder overactivity; however, its effect on symptoms in the IC/BPS population has yet to be studied. METHODS Patients diagnosed at a single IC centre with IC/BPS undergoing standard therapy were treated with additional daily mirabegron 25 mg and seen in followup post-treatment. Patients completed the Interstitial Cystitis Symptom Index and Problem Index (ICSI/ICPI), and the Pelvic Pain and Urgency/Frequency Patient Symptom Scale (PUF) prior to and following mirabegron treatment. Global (NRS) and symptom-specific outcomes were assessed by comparing the pre- and post-treatment mean scores using tailed-t test (p<0.05 considered statistically significant). RESULTS A total of 23 patients were available for review pre- and post-mirabegron treatment. There was no significant difference in ICSI (p=0.448), ICPI (p=0.352), or PUF (p=0.869) pre- and post-treatment. Analysis of symptom-specific outcomes show statistically significant improvements in urgency (p=0.048); however, no statistically significant improvements in frequency (p=0.951) or pain (p=0.952) were observed with mirabegron therapy. CONCLUSIONS IC/BPS patients treated with mirabegron had improvement of urinary urgency, but no significant benefit in terms of pain or urinary frequency. This data suggests that mirabegron's role in the IC/BPS patient should be that of adjuvant treatment to ameliorate urgency.

Abstract
BACKGROUND Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) is a urologic chronic pelvic pain syndrome with suboptimal treatment outcomes. Catastrophizing is an empirically supported risk factor for greater IC/BPS pain. AIMS In this study, a moderated multiple mediation model is tested in which several additional psychosocial risk factors (depression, illness and wellness-focused behavioral coping strategies) are proposed as mediators or moderators in the existing relationship between catastrophizing and IC/BPS pain. DESIGN The present questionnaire study employed a cross-sectional design. SETTINGS AND PARTICIPANTS Female patients with an IC/BPS diagnosis (n = 341) were recruited at tertiary care sites. METHODS Participants completed questionnaires assessing pain, catastrophizing, behavioral coping strategies, and depressive symptoms. Aggregate factor scores were calculated following exploratory factor analyses. RESULTS It was found that patients with a greater tendency to catastrophize were more likely to engage in illness-focused coping strategies, which contributed to the reporting of greater sensory and affective pain. Furthermore, this mediating effect of illness-focused coping on affective pain was more likely to occur in those patients reporting greater depressive symptoms. CONCLUSIONS Illness-focused behavioral coping is an important mechanism between maladaptive pain cognition and aspects of patient pain, with patients reporting greater depressive symptoms at increased risk for elevated pain. Patient management techniques, including screening for catastrophizing, coping, and depression, are recommended to enrich IC/BPS management.

Abstract
Purpose Differences in the severity of subjective symptoms have been noted depending on whether a Hunner lesion is present in women with interstitial cystitis/bladder pain syndrome (IC/BPS). In this study, we aimed to identify differences in objective urodynamic parameters in women with IC/BPS according to the presence of a Hunner lesion. Methods This cross-sectional study included a total of 55 patients with IC/BPS. IC/BPS and the presence of a Hunner lesion on cystoscopy were diagnosed according to American Urological Association guidelines. The patients were categorized into a Hunner IC/BPS group and a non-Hunner IC/BPS group according to the presence of a Hunner lesion on cystoscopy. At the initial visit, a medical history was taken from all patients with IC/BPS, and they underwent symptom assessment using a 3-day voiding diary and laboratory tests. A urodynamic study was then performed before any treatment was performed. Baseline characteristics and urodynamic parameters were compared between the 2 groups. Results Of the 55 patients, 23 (41.8%) had a Hunner lesion on cystoscopy. As documented in the voiding diaries, the Hunner IC/BPS group had more frequent voids and a smaller maximal voided volume (P=0.045, P<0.001, respectively). Regarding urodynamic parameters, the mean volume at the first desire to void, normal desire to void, strong desire to void (SDV), and maximum cystometric bladder capacity (MBC) was significantly lower in the Hunner IC/BPS group (P=0.001, P=0.004, P<0.001, and P<0.001, respectively). On receiver operating characteristic curve analysis, patients with an SDV≤210 mL (area under the curve [AUC]=0.838, P<0.001) and an MBC≤234 mL (AUC=0.857, P<0.001) were likely to be in the Hunner IC/BPS group. Conclusions The differences in patients’ subjective symptoms between the Hunner IC/BPS and non-Hunner IC/BPS groups were confirmed to correspond to differences in objective urodynamic parameters.

Abstract
INTRODUCTION Many clinicians have suggested that a history of bladder and bowel dysfunction (BBD) in childhood predisposes to the development of interstitial cystitis/bladder pain syndrome (IC/BPS) or irritable bowel syndrome (IBS) in adulthood. We hypothesized that BBD symptoms in childhood would predict the IBS-associated phenotype in adult IC/BPS patients. METHODS Consecutive female patients (n=190) with a diagnosis of IC/BPS were administered a modified form of a clinical BBD questionnaire (BBDQ) to capture childhood BBD-like symptoms, as well as Interstitial Cystitis Symptoms Index (ICSI), Interstitial Cystitis Problem Index (ICPI), Pelvic Pain and Urgency/Frequency (PUF) questionnaires and UPOINT categorization. Patients were stratified to IBS-positive or IBS-negative according to clinical assessment of IBS-like symptoms. RESULTS The 127 patients (67%) identified with IBS-like symptoms recalled significantly higher BBDQ scores than the 63 patients (33%) who were IBS-negative (2.8 vs. 2.3; p=0.05). The IBS-positive patients also reported a higher number of UPOINT domains than their non-IBS counterparts (3.8 vs. 2.9; p=0.0001), while their PUF total scores were significantly higher (13.6 vs. 12.3; p=0.04). IBS-positive patients more often recalled that in childhood they did not have a daily bowel movement (BM) (p=0.04) and had "to push for a BM" (p=0.009). In childhood, they "urinated only once or twice per day" (p=0.03) and recalled "painful urination" more than those without IBS (p=0.03). There were no significant differences between the groups in answers to the other five questions of the BBDQ. CONCLUSIONS Our symptom recollection survey was able to predict the IBS phenotype of IC/BPS based on a childhood BBDQ. Further prospective studies are needed to further evaluate these novel findings.

Abstract
Cystoscopy and cystodistension have been part of common treatment protocols for a variety of bladder conditions for many years. However, the science behind the procedure is not strong and continued use of the operation may not be justified. Much research is old and was not planned or executed with the current rigour demanded by current trial methods. Newer treatments such as intravesical botulinum toxin have been extensively researched and found to be effective. This review article aimed to review the evidence behind the use of cystodistension for overactive bladder (OAB) with the aim of identifying the weaknesses in the current evidence. The article aimed to identify whether a general anaesthetic cystoscopy and distension has sufficient evidence to recommend its continued use in current practice for patients with OAB resistant to conservative and drug therapies. Impact statement Cystodistension is often used in current practice in patients with overactive bladder (OAB) resistant to conservative and drug therapies. Older data suggested that this may be of benefit but there are no randomized controlled trails with appropriate assessment of symptoms and quality of life outcomes. This paper reviews the current evidence regarding the use of cystodistension in patients with OAB. There is no standardized method of cytodistension making direct comparisons difficult. The data consists of case series from individual units. Some series show benefit but in most cases this is not sustained. Initial improvement may fall to around 10-20% after 6 months. Urodynamic parameters may also fail to improve. The procedure is associated with a complication rate of 10-20%. A randomised controlled trial of cystodistension is needed to identify if this procedure should be performed for patients with OAB.

Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is a heterogeneous syndrome which is usually characterized by urinary frequency, nocturia, and bladder pain. Several pathomechanisms have been proposed, including uroepithelial dysfunction, mast cell activation, neurogenic inflammation, autoimmunity, and occult urinary tract infections. It is possible that an inflammatory process alters regulation of urothelial homeostasis and results in dysfunction of the bladder epithelium. Different phenotypes of IC/BPS have been explored including Hunner and non-Hunner type IC, hypersensitive bladder, and bladder pain both with and without functional somatic syndrome. Different gene expressions have also been found in different IC phenotypes. Abnormal expressions of uroplakin, chondroitin sulfate and adhesive protein E-cadherin, tight junction protein zonula occludens-1 in IC/BPS bladder suggest abnormal epithelial differentiation in this bladder disease. Analysis of inflammatory proteins, or cytokines in the urine or serum provides another diagnostic foundation forIC/BPS subtypes. The involvement of IC/BPS in systemic functional somatic syndrome and other pelvic organ diseases might also subdivide subtypes of IC/BPS. Chronic inflammation, increased urothelial apoptosis, and abnormal urothelial function are closely associated in IC bladders. This article reviews recent research on the pathomechanisms of IC, which might help us in mapping the heterogeneity of the disease.

Abstract
OBJECTIVE Intravesical BCG therapy is widely used for the treatment of high-risk, non-muscle-invasive bladder cancer. Among various reported side-effects, decreased bladder capacity is a serious side-effect that significantly worsens patients' quality of life. This article reports the efficacy and safety of bladder hydrodistension (BHD) in six patients with seriously decreased bladder capacity caused by BCG treatment. METHODS Six patients with low bladder capacity (<100 ml in voiding diaries) and complaint of grade 3 irritative symptoms were diagnosed with decreased bladder capacity and treated with BHD. Alleviation of symptoms was defined as medication being discontinued or reduced after BHD. RESULTS Five patients were male and one was female, and the mean age was 67.7 years. The mean interval between the last transurethral resection and BCG therapy was 26.0 days. Before BHD, all patients had been treated with antibiotics, anticholinergics and non-steroidal anti-inflammatory drugs (NSAIDs). The median bladder capacity before treatment was 40 ml (range 30-100 ml), and the median capacity increased to 200 ml (175-250 ml) within 2 weeks following BHD therapy. Four patients stopped NSAID use and three patients stopped anticholinergic use. One patient needed total cystectomy for recurrent symptoms. With a median follow-up period of 32 months, the bladder capacity remained stable without symptomatic deterioration in the remaining five patients. There was neither tumor spread nor disseminated tuberculosis infection. CONCLUSIONS BHD appears to be an effective treatment option in patients with severely decreased bladder capacity. Its efficacy and safety were acceptable.

Abstract
INTRODUCTION The main objective of the study was to assess the apoptotic effect of urine from patients with interstitial cystitis (IC) in cell cultures and to study its value as a diagnostic biomarker for IC. MATERIAL AND METHODS A prospective study was conducted between January 2010 and January 2015 and included 57 patients diagnosed with IC and 50 healthy patients from the Hospital Clinic of Barcelona and the La Paz University Hospital. The urine of these patients was exposed to cell cultures, and its ability to induce apoptosis in the cultures was analysed. Using flow cytometry, we then measured the degree of apoptosis, quantified by the percentage of cells of the cell cycle in phase sub G0. RESULTS The cell cultures exposed to the urine of patients with IC had a sub G1 peak and a G2 phase, which was significantly greater than that of the control group, and a significantly lower percentage in the S phase than the control group. The mean apoptosis values in the urine cultures from patients with IC were significantly higher than those of the control group. Using a value >10% of the apoptosis test as a positive result, we observed a specificity of 96% and a positive predictive value of 92%. CONCLUSIONS The urine of patients with IC exerts an apoptotic effect on tumour cell cultures that is significantly greater than that exerted by the urine of healthy control patients. A≥10% cutoff for the apoptosis test presented very low sensitivity (40%) but had a very high specificity (96%), thereby able to confirm the diagnosis of IC when positive.
