Abstract
Hemorrhagic cystitis may be induced by infection, radiation therapy, or medications or may be idiopathic. Along with hemorrhagic features, symptoms include urinary urgency and frequency, dysuria (painful urination), and visceral pain. Cystitis-induced visceral pain is one of the most challenging types of pain to treat, and an effective treatment would address a major unmet medical need. We assessed the efficacy of a purine nucleoside phosphorylase inhibitor, 8-aminoguanine (8-AG), for the treatment of hemorrhagic/ulcerative cystitis. Lower urinary tract (LUT) function and structure were assessed in adult Sprague-Dawley rats, treated chronically with cyclophosphamide (CYP; sacrificed day 8) and randomized to daily oral treatment with 8-AG (begun 14 days prior to CYP induction) or its vehicle. CYP-treated rats exhibited multiple abnormalities, including increased urinary frequency and neural mechanosensitivity, reduced bladder levels of inosine, urothelial inflammation/damage, and activation of spinal cord microglia, which is associated with pain hypersensitivity. 8-AG treatment of CYP-treated rats normalized all observed histological, structural, biochemical, and physiological abnormalities. In cystitis 8-AG improved function and reduced both pain and inflammation likely by increasing inosine, a tissue-protective purine metabolite. These findings demonstrate that 8-AG has translational potential for reducing pain and preventing bladder damage in cystitis-associated LUT dysfunctions.

Abstract
Pelvic cancer survivors who were treated with radiation therapy are at risk for developing (hemorrhagic) radiation cystitis (RC) many years after completion of radiation therapy. Patients with RC suffer from lower urinary tract symptoms, including frequency, nocturia, pelvic pain, and incontinence. In advanced stages, hematuria can occur, potentially escalating to life-threatening levels. Current therapeutic options for RC are limited, partly due to ethical concerns regarding bladder biopsy in patients with fragile bladder tissue. This study aimed to leverage our established preclinical model to elucidate the molecular pathways implicated in radiation-induced tissue changes in the bladder. Female C57Bl/6 mice received a single dose of 40 Gy using CT-guided imaging and a two-beam irradiation approach using the SARRP irradiator. Bladders from irradiated and age-matched littermate controls were harvested at 1 week [n = 5/group] or 6 months [n = 5/group] after irradiation, RNA was harvested, and mRNA sequencing was performed at paired-end 150bp on the Illumina NovaSeq6000 with a target of 30 million reads per sample. Following RNA sequencing, thorough bioinformatics analysis was performed using iPathwayGuide v2012 (ADVAITA Bioinformatics). Findings of the RNA sequencing were validated using qPCR analysis. At 1 week post-irradiation, altered gene expression was detected in genes involved in DNA damage response, apoptosis, and transcriptional regulation. By 6 months post-irradiation, significant changes in gene expression were observed in inflammation, collagen catabolism, and vascular health. Affected pathways included the p53, JAK-STAT, and PI3K-Akt pathways. These findings were validated in vivo in bladder tissues from our preclinical model. This is the first study to determine the molecular changes in the bladder in response to radiation treatment. We have successfully pinpointed several pathways and specific genes that undergo modification, thereby contributing to the progression of radiation cystitis. These insights enhance our understanding of the pathophysiology of radiation cystitis and may ultimately pave the way to the identification of potential new therapeutic targets.

Abstract
Cyclophosphamide (CYP) is commonly used to treat cancer of the ovaries, breast, lymph, and blood system and produces interstitial cystitis (IC) via its urotoxic metabolite: i. e., acrolein. The present study was aimed to investigate the uroprotective effect of campesterol (a steroidal phytochemical) in cyclophosphamide induced IC. IC was induced by CYP (150 mg/kg, i. p.) in rats. The Enzyme linked immunosorbent assays for oxidative stress markers and Polymerase Chain Reaction (PCR) for inflammatory cytokines were carried out. The Tissue Organ Bath Technique was used for the evaluation of the spasmolytic effect of campesterol. Different pharmacological antagonists have been used to explore the mechanism of action of campesterol. Treatment with campesterol (70 mg/kg) reduced nociception (55 %), edema (67 %), hemorrhage (67 %), and protein leakage significantly (94 %). The antioxidant activity of campesterol was exhibited by a fall in MDA, NO, and an elevation in SOD, CAT, and GPX levels. Campesterol presented anti-inflammatory potential by decreasing IL-1, TNF-α, and TGF-β expression levels. Histologically, it preserved urothelium from the deleterious effect of CYP. Campesterol showed a spasmolytic effect by reducing bladder overactivity that was dependent on muscarinic receptors, voltage-gated calcium and KATP channels, and cyclo-oxygenase pathways. In silico studies confirmed the biochemical findings. The findings suggest that campesterol could be valorized as a possible therapeutic agent against cyclophosphamide-induced interstitial cystitis.

Abstract
BACKGROUND Chemotherapeutic agents are used to treat a wide range of cancer types, but they cause serious side effects which must be managed after treatment. Cyclophosphamide (CYP) is one of chemotherapeutic drugs that causes hemorrhagic cystitis (HC) induced by acrolein. OBJECTIVE The current investigation intended to uncover the role of chrysin (CHR) in CYP-induced HC in rats and explore the signaling pathway beyond this effect. ANALYSIS process: A single dose of CYP (200 mg/kg/IP) was injected, meanwhile CHR (25, 50 and 100 mg/kg, P.O) was administered respectively for 7 days prior to CYP administration and resume for 7 days afterwards. Urinary bladder tissue was then isolated from all rats to assess oxidative stress and inflammatory biomarkers. Moreover, histopathological examinations were performed. RESULTS Treatment with CHR showed a marked alleviation in oxidative stress biomarkers induced by CYP. Furthermore, CHR treatment presented a dose-dependent boost in the anti-inflammatory; IL-10 levels and a drop in the pro-inflammatory biomarkers; IL-1β, IL-6, and TNF-α. Additionally, stabilization of the PARP-1 protein expression was also detected thus preventing DNA damage. Similarly, CHR restored the urinary bladder cGMP levels. Notably, CHR treatment was accompanied with inhibition in NF-κB/p38-MAPK, NO/PARP-1 and STAT-3 signaling pathways inflammatory cascades. All these findings conformed with the histopathological examinations as well as iNOS immunostaining in the urinary bladder tissue. CONCLUSION Co-administration of CHR and CYP attained uro-protective therapeutic potential to guard against HC as well as spot the tangled mechanism of CHR in attenuating the HC induced by CYP.

Abstract
This brief communication describes a rare spontaneous background lesion in the lower urinary tract of two male laboratory beagles. Proliferative lesions comprising a constellation of histological features consistent with polypoid cystitis were observed in the bladder of two adolescent dogs from a routine preclinical toxicology study. Both animals were clinically asymptomatic and had only minor alterations in urinalysis parameters. While chronic polypoid cystitis is well-recognized in adult pet dogs, this is the first reported case in purpose-bred laboratory beagles. An awareness of this uncommon background finding is important for toxicological pathologists to distinguish it from potential test article-related findings.

Abstract
Acrolein is the main toxic metabolite of ifosfamide (IFO) that causes urothelial damage by oxidative stress and inflammation. Here, we investigate the molecular mechanism of action of gingerols, Zingiber officinale bioactive molecules, as an alternative treatment for ifosfamide-induced hemorrhagic cystitis. Female Swiss mice were randomly divided into 5 groups: control; IFO; IFO + Mesna; and IFO + [8]- or [10]-gingerol. Mesna (80 mg/kg, i.p.) was given 5 min before, 4 and 8 h after IFO (400mg/kg, i.p.). Gingerols (25 mg/kg, p.o.) were given 1 h before and 4 and 8 h after IFO. Animals were euthanized 12 h after IFO injection. Bladders were submitted to macroscopic and histological evaluation. Oxidative stress and inflammation were assessed by malondialdehyde (MDA) or myeloperoxidase assays, respectively. mRNA gene expression was performed to evaluate mesna and gingerols mechanisms of action. Mesna was able to protect bladder tissue by activating NF-κB and NrF2 pathways. However, we demonstrated that gingerols acted as an antioxidant and anti-inflammatory agent stimulating the expression of IL-10, which intracellularly activates JAK/STAT/FOXO signaling pathway.

Abstract
PURPOSE We identify correlates and clinical outcomes of cystitis cystica, a poorly understood chronic inflammatory bladder change, in women with recurrent urinary tract infections. MATERIALS AND METHODS A retrospective, observational cohort of women with recurrent urinary tract infections who underwent cystoscopy (n=138) from 2015 to 2018 were identified using electronic medical records. Cystitis cystica status was abstracted from cystoscopy reports and correlations were identified by logistic regression. Urinary tract infection-free survival time associated with cystitis cystica was evaluated by Cox proportional hazards regression. Exact logistic regression was used to identify factors associated with changes to cystitis cystica lesions on repeat cystoscopy. Biopsies of cystitis cystica lesions were examined by routine histology and immunofluorescence. RESULTS Fifty-three patients (38%) had cystitis cystica on cystoscopy. Cystitis cystica was associated with postmenopausal status (OR: 5.53, 95% CI: 1.39-37.21), pelvic floor myofascial pain (6.82, 1.78-45.04), having ≥4 urinary tract infections in the past year (2.28, 1.04-5.09), and a shorter time to next urinary tract infection (HR: 1.54, 95% CI: 1.01-2.35). Forty-two patients (82%) demonstrated improvement or resolution of lesions. Ten/11 (91%) biopsied cystitis cystica lesions were tertiary lymphoid tissue with germinal centers and resembled follicular cystitis. CONCLUSIONS Cystitis cystica lesions were associated with postmenopausal status, pelvic floor myofascial pain, and number of urinary tract infections in the prior year and predicted worse recurrent urinary tract infection outcomes. Cystitis cystica lesions are tertiary lymphoid tissue/follicular cystitis that may improve or resolve over time with treatment. Identifying cystitis cystica in recurrent urinary tract infection patients may be useful in informing future urinary tract infection risk and tailoring appropriate treatment strategies.

Abstract
Tissue mechanics determines tissue homeostasis, disease development and progression. Bladder strongly relies on its mechanical properties to perform its physiological function, but these are poorly unveiled under normal and pathological conditions. Here we characterize the mechanical fingerprints at the micro-scale level of the three tissue layers which compose the healthy bladder wall, and identify modifications associated with the onset and progression of pathological conditions (i.e., actinic cystitis and bladder cancer). We use two indentation-based instruments (an Atomic Force Microscope and a nanoindenter) and compare the micromechanical maps with a comprehensive histological analysis. We find that the healthy bladder wall is a mechanically inhomogeneous tissue, with a gradient of increasing stiffness from the urothelium to the lamina propria, which gradually decreases when reaching the muscle outer layer. Stiffening in fibrotic tissues correlate with increased deposition of dense extracellular matrix in the lamina propria. An increase in tissue compliance is observed before the onset and invasion of the tumor. By providing high resolution micromechanical investigation of each tissue layer of the bladder, we depict the intrinsic mechanical heterogeneity of the layers of a healthy bladder as compared with the mechanical properties alterations associated with either actinic cystitis or bladder tumor.

Abstract
Spinal mechanisms associated with visceral hypersensitivity are poorly understood. One model of bladder hypersensitivity with phenotypic features similar to the disorder interstitial cystitis/bladder pain syndrome is the neonatal bladder inflammation (NBI) model. In this model, rat pup bladders are infused with zymosan solutions on post-partum days 14-16 and then rats are retested as adults. Studies of other sites of deep tissue hypersensitivity have suggested a role for corticotropin-releasing factor (CRF) receptors type 1 and 2 (CRFR1 and CRFR2). Using neurochemical measures, pharmacological manipulations and both reflex and neuronal responses to urinary bladder distension as endpoints, the present study probed the role of CRFR2s in bladder hyperalgesia secondary to NBI and acute bladder re-inflammation as an adult (ABI). ELISA measures of the lumbosacral spinal cord demonstrated increased CRFR1s and CRFR2s following pretreatment with both NBI + ABI as well as NBI-related increases in the CRFR2 agonist urocortin 2. Intrathecal CRFR2 antagonists, but not a CRFR1 antagonist, blocked the augmentation of visceromotor responses to distension following pretreatment with both NBI + ABI. Lumbosacral dorsal horn neuronal responses to distension in rats pretreated with NBI + ABI were attenuated by the spinal topical administration of a CRFR2 antagonist. These studies suggest therapeutic value of CRFR2 antagonists in the treatment of painful bladder disorders.

Abstract
Radiation cystitis, a long-term bladder defect due to pelvic radiation therapy, results in lower urinary tract symptoms, such as urinary frequency and nocturia, suggestive of compromised bladder compliance. The goal of this study was to identify alterations to the mechanical behavior of the urinary bladder extracellular matrix of a murine model of radiation cystitis, at 3 and 6 months after radiation exposure. The results of this study demonstrated that the extracellular matrix of irradiated bladders was significantly less distensible when compared to age matching controls. These findings coincided with functional bladder changes, including increased number of voids and decreased voided volume. Both mechanical and functional changes were apparent at 3 months post-irradiation and were statistically significant at 6 months, demonstrating the progressive nature of radiation cystitis. Overall, the results of this study indicate that irradiation exposure changes both the mechanical and physiological properties of the bladder. STATEMENT OF SIGNIFICANCE: In humans, radiation cystitis results in lower urinary tract symptoms, such as urinary frequency and nocturia, suggestive of compromised bladder compliance. This pathology can significantly affect recovery and quality of life for cancer survivors. Gaining knowledge about how alterations to the mechanical behavior of the urinary bladder extracellular matrix can affect urinary function will have a significant impact on this population. The results of this study demonstrated that the extracellular matrix of irradiated bladders was significantly less distensible when compared to age matching controls, in a mouse model of radiation cystitis. These findings were accompanied by functional voiding changes, including increased number of voids and decreased voided volume. The results of this study uncovered that irradiation exposure changes the mechanical and physiological properties of the bladder.

Abstract
Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of advanced melanoma. Combination of ICI with ipilimumab cytotoxic T-lymphocyte antigen-4 and nivolumab [anti-programmed cell death-1 (PD-1)] improves tumoral response compared to anti-PD1 monotherapy in melanoma patients, but is associated with more severe and multiple immune-related adverse events. We report the first case of aseptic cystitis induced by ipilimumab and nivolumab combination in a 61-year-old melanoma patient. She described after two infusions, diarrhea, pollakiuria, intense bladder pain, urinary urgency, and nocturia. Repeated negative urine culture tests led to perform cystoscopy. Mucosal bladder biopsies showed lymphocytic T-cells infiltration in intraepithelial and in subepithelial connective tissue, which were consistent with the diagnosis of immune-related aseptic cystitis. Aseptic cystitis is a rare and poorly known side-effect related to ICI. Only four other cases with anti-PD1 monotherapy were found in literature, only in Japanese patients. It simulates bacterial cystitis with negative urinary tests, and is often associated with atypical symptoms like diarrhea, which may delay the diagnosis. Oral steroids appear to be the most efficient therapeutic options.

Abstract
Pachymic acid (PA), a bioactive ingredient isolated from Poria cocos Wolf, is reported with potential benefits of anti-inflammatory, anti-oxidative actions. It is reasoned that PA may play the potential benefits against cystitis glandularis (CG), an inflammation of the bladder tissue. In this study, we aimed to apply the network pharmacology and molecular docking analyses to reveal concrete anti-CG targets and mechanisms of PA, and then the bioinformatic findings were verified by using clinical and animal samples. The methodological data from network pharmacology approach showed that 303 and 243 reporting targets of CG and PA, and other 31 shared targets of CG and PA were identified. Subsequently, all top targets of PA against CG were screened out, including cyclooxygenase-2, epidermal growth factor receptor, tumor antigen p53 (TP53), tumor necrosis factor-alpha (TNF), interleukin-1 (IL-1) beta, proto-oncogene c-jun. Molecular docking data demonstrated that PA exerted potent bonding capacities with TNF, TP53 proteins in CG. In human study, the findings suggested that overactivated TNF-α expression and suppressed TP53 activation were detected in CG samples. In animal study, PA-treated mice showed reduced intravesical IL-1, IL-6 levels, and lactate dehydrogenase content, downregulated TNF-α and upregulated TP53 proteins in bladder samples. Taken together, our bioinformatics and experimental findings identify the key anti-CG biotargets and mechanisms of PA. More markedly, these pivotal pharmacological targets of PA against CG have been screened out and verified by using computational and experimental analyses.

Abstract
Although interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic condition causing bladder pain and urinary symptoms, effective treatments have not been established. The aim of this study was to adapt a chronic cystitis model in rats using lipopolysaccharide (LPS), which reflects IC/BPS pathology, and characterize the model's histological and behavioral effects. Furthermore, we investigated the effect of an α2 δ subunit ligand, gabapentin (GBP), on bladder hypersensitivity of rats with chronic cystitis. Cystitis models were created by repeated intravesical injections of LPS. In the histological examination, the LPS-injected group had greater inflammatory response, fibrosis, and abnormally thick re-epithelialization. In the LPS-injected group, LPS prompted hyperalgesia in both the lower abdomen and hind paw regions after day 1 of the first injection compared with the saline-injected controls, without any recovery for 21 days at least. During cystometry, the LPS-injected group showed bladder hyperactivity at all times. Systemic administration of GBP reduced cystitis-related pain due to chronic inflammation and reduced the increased frequency of voiding in the LPS-injected group. These results suggest that repeated intravesical injections of LPS induce long-lasting bladder inflammation, pain, and overactivity in rats, while GBP is effective in the management of those symptoms in this chronic cystitis model. The current study identifies a relatively simple method to develop an animal model for chronic cystitis and provides evidence that GBP may be an effective treatment option for patients with IC/BPS.

Abstract
Ketamine is a versatile analgesic that has become an increasingly popular recreational drug. Chronic ketamine use has been found to cause biliary duct damage and bladder dysfunction. Ketamine-induced cholangiopathy and ulcerative cystitis are uncommon diagnoses presenting with nonspecific symptoms, creating diagnostic challenges for emergency physicians. We report a case of a teenage patient with the rare simultaneous presentation of ketamine-induced cholangiopathy and ulcerative cystitis. Due to increased recreational and chronic ketamine use, cases of ketamine-induced cholangiopathy and ulcerative cystitis are likely to rise with the increased knowledge, awareness, and reporting of these entities by radiologists and emergency physicians.

Abstract
Radiation therapy for malignant tumors of the female genital area, even with the use of modern radiotherapy equipment and dosimetric planning, causes the development of local radiation changes. An approach involving methodsof general and local exposure is used in their treatment. One of the most promising directions is the creation of optimal combinations of medicines (in the form of ointments, gels, aerosols, suppositories, etc.), which have a therapeutic effect on the inflammatory process. The article reflects the clinical course and stage of occurrence of late radiation reactions of the skin, vaginal/cervix mucosa, bladder, and intestines, as well as the features of their treatment.Literary data and own practical experience in the treatment of radiation complications are presented. Whenreviewing the topic under study, it could be concluded that the leading cause of the development of local radiationdamage is the errors in the planning and implementation of radiation therapy, when high absorbed doses thatexceed the tolerance of healthy tissues are used. Another reason for this is the poor accounting for dose distribution of ionizing radiation in tissues, the presence of concomitant diseases in patients, and the underestimation ofthe long-term effects of radiation.

Abstract
Radiation for pelvic cancers can result in severe bladder damage and radiation cystitis (RC), which is characterized by chronic inflammation, fibrosis, and vascular damage. RC development is poorly understood because bladder biopsies are difficult to obtain. The goal of this study is to gain understanding of molecular changes that drive radiation-induced cystitis in cancer survivors using urine samples from prostate cancer survivors with history of radiation therapy. 94 urine samples were collected from prostate cancer survivors with (n = 85) and without (n = 9) history of radiation therapy. 15 patients with radiation history were officially diagnosed with radiation cystitis. Levels of 47 different proteins were measured using Multiplex Luminex. Comparisons were made between non-irradiated and irradiated samples, and within irradiated samples based on radiation cystitis diagnosis, symptom scores or hematuria. Statistical analysis was performed using Welch’s t-test. In prostate cancer survivors with history of radiation therapy, elevated levels of PAI 1, TIMP1, TIMP2, HGF and VEGF-A were detected in patients that received a radiation cystitis diagnosis. These proteins were also increased in patients suffering from hematuria or high symptom scores. No inflammatory proteins were detected in the urine, except in patients with gross hematuria and end stage radiation cystitis. Active fibrosis and vascular distress is detectable in the urine through elevated levels of associated proteins. Inflammation is only detected in urine of patients with end-stage radiation cystitis disease. These results suggest that fibrosis and vascular damage drive the development of radiation cystitis and could lead to the development of more targeted treatments.

Abstract
Tuberculosis (TB) is a multi-systemic disease instigated by Mycobacterium tuberculosis that can involve any organ. In any child presenting with clinical features involving multiple organ systems, TB forms an important differential. This holds particularly for endemic countries like India. Genitourinary TB (GUTB) comprises up to 27% of all extrapulmonary TB cases. We present an unusual presentation of disseminated TB involving kidneys and presenting as gross hematuria. 12-year-old girl, presented with recurrent episodes of gross hematuria of one-month duration. She received multiple packed cell transfusions for the same. She had chronic malnutrition. USG KUB with renal doppler was normal. Given persistent hematuria, CT urography was done which showed features suggestive of papillary necrosis with cystitis. Tubercular workup showed multiple opacities predominantly involving perihilar regions bilaterally on chest x-ray along with positive Mantoux test. Sputum for AFB was positive for tubercular bacilli. Urine samples were also sent for CBNAAT which showed TB bacilli sensitive to rifampicin. With a diagnosis of disseminated TB, antitubercular therapy (ATT) was started followed by cystoscopic resection of inflamed bladder wall tissue. Bladder mucosal biopsy confirmed caseating granulomas suggestive of tuberculous cystitis. The patient is doing well and symptom-free after completion of ATT.

Abstract
Hemorrhagic cystitis is one of the most important complications of cyclophosphamide, a drug widely used in cancer chemotherapy and bone marrow transplantation. 5-HT3 antagonists are anti-emetic agents and have been shown to have notable anti-inflammatory and antioxidant properties. This study was designed to investigate the possible protective effects of tropisetron against cyclophosphamide-induced hemorrhagic cystitis in rats. Hemorrhagic cystitis was induced in female rats by cyclophosphamide (270 mg/kg). Tropisetron (2.5, 5 and 7.5 mg/kg), granisetron (2.5 and 5 mg/kg), and ondansetron (5 mg/kg) were injected 15 min before, 4 and 8 h after cyclophosphamide. To evaluate the role of alpha7 nicotinic acetylcholine receptor (α7nAChR), its antagonist, methyllycaconitine (5 mg/kg) was administered 30 min before tropisetron. After 24 h, animals were killed under anesthesia. Macroscopic and histological changes were evaluated. Malondialdehyde (MDA), glutathione (GSH) and Evans blue were measured spectrophotometrically. Furthermore, the protein levels of p38 mitogen-activated protein kinases (P38 MAPK), p-P38, signal transducer and activator of transcription 3 (STAT3), p-STAT3 and Poly (ADP-ribose) polymerase (PARP) were determined using Western blot. Cyclophosphamide administration significantly induced histopathological damages and increased MDA, p-p38/p38, p-STAT3/STAT3, and PARP levels compared with the saline group. Tropisetron treatment diminished histopathological injuries as well as MDA level, and STAT3 activity compared to cyclophosphamide treated rats. Co-administration of methyllycaconitine with tropisetron, partially or completely reversed the protective effects of tropisetron. Our results showed that prophylactic administration of tropisetron markedly ameliorated the cyclophosphamide-induced bladder hemorrhage and inflammation in rats. These effects of tropisetron were α7nAChR dependent.

Abstract
Urinary tract infections (UTIs) typically evoke prompt and vigorous innate bladder immune responses, including extensive exfoliation of the epithelium. To explain the basis for the extraordinarily high recurrence rates of UTIs, we examined adaptive immune responses in mouse bladders. We found that, following each bladder infection, a highly T helper type 2 (TH2)-skewed immune response directed at bladder re-epithelialization is observed, with limited capacity to clear infection. This response is initiated by a distinct subset of CD301b+OX40L+ dendritic cells, which migrate into the bladder epithelium after infection before trafficking to lymph nodes to preferentially activate TH2 cells. The bladder epithelial repair response is cumulative and aberrant as, after multiple infections, the epithelium was markedly thickened and bladder capacity was reduced relative to controls. Thus, recurrence of UTIs and associated bladder dysfunction are the outcome of the preferential focus of the adaptive immune response on epithelial repair at the expense of bacterial clearance.

Abstract
Purpose This retrospective study aims at investigating the effects of moderately hypofractionated radiation therapy (HRT) on acute and late toxicities as well as on early biochemical control and therapeutic efficiency compared to conventional radiation therapy (CRT) in prostate cancer. Patients and methods We analyzed 55 HRT patients irradiated with the total dose of 60 Gy in 20 fractions delivered over 4 weeks. These patients were compared to a control group of 55 patients who received CRT with a total of <78 Gy in 37–39 fractions delivered over circa 8 weeks. External beam radiation therapy (EBRT) was conducted using daily image-guided (cone beam CT) volumetric modulated arc therapy (VMAT) and a simultaneously integrated boost (SIB) for both groups to protect the rectum. Acute toxicities were evaluated according to Common Terminology Criteria for Adverse Events (CTCAE) v5, whereas chronic toxicities were assessed in accordance with LENT-SOMA. Patient traits were compared by implementing t‑tests and Wilcoxon–Whitney tests for continuous variables, whereas discrete characteristics were evaluated by applying two-tailed Fisher’s exact tests. In addition, we calculated average treatment effects (ATE). Thereby, propensity score matching (PSM) based on nearest-neighbor matching considering age, comorbidities, and risk stratification as covariates was applied. The statistical analysis was conducted using Stata 14.2 (StataCorp LLC, TX, USA). Results As confirmed by the descriptive tests, the ATE revealed that the intensity and occurrence of urinary frequency (p = 0.034) and proctitis (p = 0.027) significantly decreased for the HRT group, whereas all other acute toxicities did not differ significantly between the HRT and CRT groups. For late toxicities, neither statistical tests nor ATE estimation showed significant differences. Also, no significant difference was found regarding the decrease in prostate specific antigen (PSA) after a median follow-up of 13 months (range 2–28 months), which indicates biochemical freedom from progression. Conclusion HRT offers several medical and economic advantages and should therefore be considered as a useful alternative to CRT.

Abstract
A subset of patients receiving radiation therapy for pelvic cancer develop radiation cystitis, a complication characterized by mucosal cell death, inflammation, hematuria, and bladder fibrosis. Radiation cystitis can reduce bladder capacity, cause incontinence, and impair voiding function so severely that patients require surgical intervention. Factors influencing onset and severity of radiation cystitis are not fully known. We tested the hypothesis that genetic background is a contributing factor. We irradiated bladders of female C57BL/6, C3H, and BALB/c mice and evaluated urinary voiding function, bladder shape, histology, collagen composition, and distribution of collagen-producing cells. We found that the genetic background profoundly affects the severity of radiation-induced bladder fibrosis and urinary voiding dysfunction. C57BL/6 mice are most susceptible and C3H mice are most resistant. Irradiated C57BL/6 mouse bladders are misshapen and express more abundant collagen I and III proteins than irradiated C3H and BALB/c bladders. We localized Col1a1 and Col3a1 mRNAs to FSP1-negative stromal cells in the bladder lamina propria and detrusor. The number of collagen I and collagen III-producing cells can predict the average voided volume of a mouse. Collectively, we show that genetic factors confer sensitivity to radiation cystitis, establish C57BL/6 mice as a sensitive preclinical model, and identify a potential role for FSP1-negative stromal cells in radiation-induced bladder fibrosis.

Abstract
Keratinocyte growth factor (KGF) improves cyclophosphamide-induced bladder injury. To understand the mechanisms, we subcutaneously administered KGF to mice 24 hours before i.p. cyclophosphamide administration, followed by histologic assays and immunostaining. In vehicle (phosphate-buffered saline)-pretreated mice, nonapoptotic superficial cell death from 2 to 6 hours and apoptosis in intermediate and basal cells from 4 to 24 hours was observed after cyclophosphamide. Despite superficial cell loss, KGF suppressed intermediate and basal cell apoptosis, likely via AKT signaling. At 6 and 24 hours after cyclophosphamide, KGF-pretreated mice also had apparent extracellular signal-regulated kinase (ERK)-driven proliferation of mostly keratin 5 (KRT5)+/KRT14- intermediate cells. At 1 to 28 days after cyclophosphamide treatment, mostly KRT14+ basal progenitor cells proliferated in response to injury, peaking at 3 days in both treatment groups; however, proliferation rates were lower in the KGF group at 3 days, consistent with less injury. Three days after injury, unlike controls, KGF-pretreated mice had regenerated superficial cells. At 10 and 28 days after cyclophosphamide treatment, KGF-pretreated mice had little proliferation and marked restoration of urothelial layers, whereas the phosphate-buffered saline group had ongoing regeneration. Administration of KGF to uninjured mice reproduced ERK-driven KRT5+/KRT14- proliferation seen in injured mice; KRT14+ cells were unaffected. KGF pretreatment blocks cyclophosphamide-induced intermediate and basal cell apoptosis, likely by phosphorylated AKT, and drives phosphorylated ERK-mediated KRT5+/KRT14- cell proliferation, leading to early urothelial regeneration.

Abstract
BACKGROUND Our present study aimed to unravel the therapeutic biotargets of vitamin C (VC) against cystitis glandularis (CG), and to elucidate the molecular mechanisms for VC treating CG. METHODS Network pharmacology was used to predict therapeutic targets of VC against CG, and to identify molecular mechanisms. In addition, further human and animal studies were designed to validate the bioinformatic findings through biochemical tests, computerized tomography scans, and immunostaining assays. RESULTS In bioinformatic analyses, pathogenic targets of CG and putative targets of VC were identified, respectively. An interaction network between biological target and functional protein was produced before screening and collecting the key therapeutic targets of VC against CG, biological processes, and signaling pathways. In addition, ingenuity pathway analysis with cloud platform indicated that anti-CG mechanisms of VC were achieved through modulating a cluster of molecular pathways, such as tumor necrosis factor (TNF) pathway. Meanwhile, 18 core targets of VC against CG were identified, and the most important TNF, interleukin-6 (IL6), and Jun biotargets were obtained, respectively. In further validation in human study, cellular TNF-α, IL6, and c-Jun expressions in patient's CG samples were elevated significantly, accompanied with detectable urinary tract infection. Beneficially, VC-dosed CG mice resulted in downregulated expressions of endogenous TNF-α, IL6, and c-Jun in blood and bladder samples. CONCLUSION Collectively, these bioinformatic findings and experimentative data uncover the therapeutic targets and biological mechanisms of VC for treating CG, in which the key biomarkers of TNF-α, IL6, and c-Jun may be the potential molecules for treating CG in clinical application.

Abstract
As for the Bethesda system for cervical and thyroid cytopathology, a terminology for reporting urinary cytology has been published in 2015. The new "Paris System" provides a consensus terminology for urinary cytology which underlines the criteria for the recognition of high-grade urothelial carcinoma (HGUC) and of those excluding HGUC, or suspicious for HGUC. It also focuses on new rules to recognize and report the subgroup of "atypical urothelial cells". Here we describe and illustrate the various categories as in the reference book. We analyse the main diagnostic criteria, including microscopic features as well as the risk of malignancy associated to every diagnostic category.

Abstract
The urothelium of the bladder, renal pelvis, ureter and urethra is maintained through the regulated proliferation and differentiation of urothelial stem and progenitor cells. These cells provide a rich source of a novel urothelial cell therapy approach that could be used to protect, regenerate, repair and restore a damaged urothelium. Urothelial injury caused by physical, chemical and microbial stress is the pathological basis of cystitis (bladder inflammation). The loss of urothelial integrity triggers a series of inflammatory events, resulting in pain and hematuria such as hemorrhage cystitis and interstitial cystitis. Here we investigate a novel cell therapy strategy to treat cystitis by protecting the urothelium from detrimental stresses through intravesically instilling porcine urothelial cells (PUCs) into the bladder. Using a chemical-induced urothelial injury mouse model of cyclophosphamide (CPP)-induced hemorrhagic cystitis, we determined how the intravesical instillation of PUCs could protect the urothelium from toxic attack from CPP metabolites. We show that intravesical PUC instillation protected the bladder from toxic chemical attack in mice receiving CPP with reduced inflammation and edema. Compared with the vehicle control mice, the proliferative response to chemical injury and apoptotic cells within the bladder tissues were reduced by intravesical PUC treatment. Furthermore, the urothelium integrity was maintained in the intravesical PUC-treated group. After xenogeneic PUCs were introduced and adhered to the mouse urothelium, immunological rejection responses were observed with increased neutrophil infiltration in the lamina propria and higher immune-related gene expression. Our findings provide an innovative and promising intravesical PUC cell therapy for cystitis with urothelial injury by protecting the urothelium from noxious agents.

Abstract
OBJECTIVE To evaluate the association between diet in relation to its inflammatory property and bladder cancer (BC) risk. METHODS In this study we explored the association between the dietary inflammatory index (DII) and BC risk in an Italian case-control study conducted between 2003 and 2014. Cases were 690 patients with incident and histologically confirmed BC from 4 areas in Italy. Controls were 665 cancer-free subjects admitted to the same network of hospitals as cases for a wide spectrum of acute, non-neoplastic conditions. The DII was computed based on dietary intake assessed using a reproducible and valid 80-item food frequency questionnaire. Odds ratios (OR) were estimated through logistic regression models adjusting for age, sex, total energy intake, and other recognized confounding factors. RESULTS Subjects in the highest quartile of DII scores (ie, with a more pro-inflammatory diet) had a higher risk of BC compared to subjects in the lowest quartile (ie, with an anti-inflammatory diet) (ORQuartile4vs1 = 1.97; 95% [confidence interval], 1.28, 3.03; P trend = .003). Stratified analyses produced stronger associations between DII and BC risk among females (ORQuartile4vs1 = 5.73; 95% CI = 1.46, 22.44), older ≥65 years (ORQuartile4vs1 = 2.45; 95% CI = 1.38, 4.34), subjects with higher education ≥7 years (ORQuartile4vs1 = 2.22; 95% CI = 1.27, 3.88), and never smokers (ORQuartile4vs1 = 4.04; 95% CI = 1.51, 10.80). CONCLUSION A pro-inflammatory diet as indicated by higher DII scores is associated with increased BC risk.

Abstract
PURPOSE Hemorrhagic cystitis (HC) is the most common urotoxic side effect of cyclophosphamide (CYP). Platelet rich plasma (PRP) plays an important role in wound healing and inflammatory responses. The aim of this study was to investigate the efficacy of intravesical PRP at treatment of interstitial cystitis (IC). MATERIAL-METHODS Female rats (n=24) were used. IC was induced by intraperitoneal injection of cyclophosphamide (CYP). Rats were randomly allocated to one of four groups (n = 6 per group): a control group; a sham group with saline (75 mg/kg; i.p.) instead of CYP on day 1; a IC group, which was injected with CYP (150 mg/kg; i.p.) on day 1; and, a intravesical PRP‑treated group which was injected with CYP (150 mg/kg; i.p.) on day 1. On day 2, the rats in each group were sacrificed under anesthesia. RESULTS Histological evaluation showed that bladder inflammation in CYP‑treated rats was not suppressed by PRP. CYP administration induced severe IC with marked edema, hemorrhage and inflammation in CYP and CYP+PRP groups, but PRP was not found to be effective to decrease these effects. CONCLUSION The application of PRP could not reverse the histopathological changes in rats that had interstitial cystitis due to the cyclophosphamide injection.

Abstract
Uropathogenic E. coli (UPEC) is the dominant cause of urinary tract infections, clinically described as cystitis. UPEC express CUP pili, which are extracellular fibers tipped with adhesins that bind mucosal surfaces of the urinary tract. Here we identify the role of the F9/Yde/Fml pilus for UPEC persistence in the inflamed urothelium. The Fml adhesin FmlH binds galactose β1-3 N-acetylgalactosamine found in core-1 and -2 O-glycans. Deletion of fmlH had no effect on UPEC virulence in an acute mouse model of cystitis. However, FmlH provided a fitness advantage during chronic cystitis, which is manifested as persistent bacteriuria, high bladder bacterial burdens, and chronic inflammation. In situ binding confirmed that FmlH bound avidly to the inflamed, but not the naive bladder. In accordance with its pathogenic profile, vaccination with FmlH significantly protected mice from chronic cystitis. Thus, UPEC employ separate CUP pili to adapt to the rapidly changing niche during bladder infection.

Abstract
Recent evidence indicates that antimicrobial peptides (AMPs) serve key roles in defending the urinary tract against invading uropathogens. To date, the individual contribution of AMPs to urinary tract host defense is not well defined. In this study, we identified Regenerating islet-derived 3 gamma (RegIIIγ) as the most transcriptionally up-regulated AMP in murine bladder transcriptomes following uropathogenic Escherichia coli (UPEC) infection. We confirmed induction of RegIIIγ mRNA during cystitis and pyelonephritis by quantitative RT-PCR. Immunoblotting demonstrates increased bladder and urinary RegIIIγ protein levels following UPEC infection. Immunostaining localizes RegIIIγ protein to urothelial cells of infected bladders and kidneys. Human patients with UTI have increased urine concentrations of the orthologous Hepatocarcinoma-Intestine-Pancreas / Pancreatitis Associated Protein (HIP/PAP) compared to healthy controls. Recombinant RegIIIγ protein does not demonstrate bactericidal activity toward UPEC in vitro, but does kill Staphylococcus saprophyticus in a dose-dependent manner. Kidney and bladder tissue from RegIIIγ knockout mice and wild-type mice contain comparable bacterial burden following UPEC and Gram-positive UTI. Our results demonstrate that RegIIIγ and HIP/PAP expression is induced during human and murine UTI. However, their specific function in the urinary tract remains uncertain.

Abstract
Female hypospadias presenting as a misplaced urethral opening is a common cause of chronic recurrent cystitis. Cystitis occurs when urogenital infection and anaerobic bacteria enter the urethra and bladder from the vagina. The authors argue that chronic infections of the lower urinary tract in women with hypospadias should be treated surgically by meatal transposition. They present a study confirming the role of the antiviral drug Panavir in prevention of inflammatory complications in the postoperative period in patients with a history of viral infection (human papillomavirus and herpes).

Abstract
Comprehensive clinical and morphological examination of 60 female patients with chronic pelvic pain syndrome after combined chronic cystitis and adenomyosis was carried out. In all patients, the complex urodynamic examination revealed various disturbances of urination and stasis-like abnormalities of circulation in vesical and uterine walls. The pathomorphological peculiarities of the urogenital disorders during combination of adenomyosis and cystitis (of the combined proliferative and erosive/destructive type) is manifested by more pronounced destructive and inflammatory changes in urothelium characterized by the formation of superficial and deep erosions as well as by association of erosive/destructive damages to the urothelium with proliferative and metaplastic changes. Combined treatment of chronic cystitides and adenomyosis eliminated the destructive and inflammatory alterations in the vesical mucosa in 70 and 93% female patients, respectively (the corresponding values after basic therapy were 60 and 77%), and pronouncedly ameliorated pain syndrome.

Abstract
Eosinophilic gastroenteritis (EG) is a rare, distinct clinical entity, and EG associated with eosinophilic cystitis (EC) is extremely rare and has not been well documented. Here, we report two cases of EG and coexistent EC along with findings from computed tomography (CT) and magnetic resonance imaging (MRI). An 18-year-old male with a history of hematuria, urgency and occasional urodynia for two weeks and a 34-year-old male with a history of abdominal distention for one week were admitted to our hospital. Abdominal contrast-enhanced CT in both patients revealed wall thickening in different parts of the gastrointestinal tract with inhomogeneous reinforcement, coexistent with local or diffuse bladder wall thickening with progressive enhancement, and also showed that the bladder mucosal lining was nondestructive. Pelvic MRI showed that the local or diffuse thickened bladder wall was iso-intense on T1-weighted images, hypo-intense on T2-weighted images, and slightly restricted on diffusion weighted imaging (DWI) in one case. After therapy, the thickened wall of the gastrointestinal tract and urinary bladder had improved markedly in the two cases. To the best of our knowledge, this is the first report on the radiological imaging of EG and coexistent EC by both CT and MRI and the first with DWI findings.

Abstract
BACKGROUND Long-course preoperative chemoradiotherapy (chemo-RT) improves outcomes for rectal cancer patients, but acute side effects during treatment may cause considerable patient discomfort and may compromise treatment compliance. We developed a dose-response model for acute urinary toxicity based on a large, single-institution series. MATERIAL AND METHODS In total 345 patients were treated with (chemo-)RT for primary rectal cancer from January 2007 to May 2012. Urinary toxicity during RT was scored prospectively using the CTCAE v 3.0 cystitis score (grade 0-5). Clinical variables and radiation dose to the bladder were related to graded toxicity using multivariate ordinal logistic regression. Three models were optimized, each containing all available clinical variables and one of three dose metrics: Mean dose (Dmean), equivalent uniform dose (EUD), or relative volume given x Gy or above (dose cut-off model, Vx). The optimal dose metric was chosen using the Akaike Information Criterion (AIC). RESULTS Grade 1 cystitis was experienced by 138 (40%), grade 2 by 39 (11%) and grade 3 by two (1%) patients, respectively. Dose metrics were significantly correlated with toxicity in all models, but the dose cut-off model provided the best AIC value. The only significant clinical risk factors in the Vx model were male gender (p = 0.006) and brachytherapy boost (p = 0.02). Reducing the model to include gender, brachytherapy boost and Vx yielded odds ratios ORmale = 1.82 (1.17-2.80), ORbrachy = 1.36 (1.02-1.80 for each 5 Gy), x = 35.1 Gy (28.6-41.5 Gy). The predicted risk of grade 2 and above cystitis ranged from 2% to 26%. CONCLUSION Acute cystitis correlated significantly with radiation dose to the bladder; the dose-cut-off model (V35Gy) was superior to Dmean and EUD models. Male gender and brachytherapy boost increased the risk of toxicity. Wide variation in predicted risks suggests room for treatment optimization using individual dose constraints.

Abstract
Urinary tract infections (UTIs) afflict over 9 million women in America every year, often necessitating long-term prophylactic antibiotics. One risk factor for UTI is frequent sexual intercourse, which dramatically increases the risk of UTI. The mechanism behind this increased risk is unknown; however, bacteriuria increases immediately after sexual intercourse episodes, suggesting that physical manipulation introduces periurethral flora into the urinary tract. In this paper, we investigated whether superinfection (repeat introduction of bacteria) resulted in increased risk of severe UTI, manifesting as persistent bacteriuria, high titer bladder bacterial burdens and chronic inflammation, an outcome referred to as chronic cystitis. Chronic cystitis represents unchecked luminal bacterial replication and is defined histologically by urothelial hyperplasia and submucosal lymphoid aggregates, a histological pattern similar to that seen in humans suffering chronic UTI. C57BL/6J mice are resistant to chronic cystitis after a single infection; however, they developed persistent bacteriuria and chronic cystitis when superinfected 24 hours apart. Elevated levels of interleukin-6 (IL-6), keratinocyte cytokine (KC/CXCL1), and granulocyte colony-stimulating factor (G-CSF) in the serum of C57BL/6J mice prior to the second infection predicted the development of chronic cystitis. These same cytokines have been found to precede chronic cystitis in singly infected C3H/HeN mice. Furthermore, inoculating C3H/HeN mice twice within a six-hour period doubled the proportion of mice that developed chronic cystitis. Intracellular bacterial replication, regulated hemolysin (HlyA) expression, and caspase 1/11 activation were essential for this increase. Microarrays conducted at four weeks post inoculation in both mouse strains revealed upregulation of IL-1 and antimicrobial peptides during chronic cystitis. These data suggest a mechanism by which caspase-1/11 activation and IL-1 secretion could predispose certain women to recurrent UTI after frequent intercourse, a predisposition predictable by several serum biomarkers in two murine models. Urinary tract infections (UTIs) affect millions of women each year resulting in substantial morbidity and lost wages. Approximately 1.5 million women are referred to urology clinics suffering from chronic recurrent UTI on a yearly basis necessitating the use of prophylactic antibiotics. Frequent and recent sexual intercourse correlates with the development of UTI, a phenomenon referred to clinically as “honeymoon cystitis.” Here, using superinfection mouse models, we identified bacterial and host factors that influence the likelihood of developing chronic UTI. We discovered that superinfection leads to a higher rate of chronic UTI, which depended on bacterial replication within bladder cells combined with an immune response including inflammasome activation and cytokine release. These data suggest that bacterial inoculation into an acutely inflamed urinary tract is more likely to lead to severe UTI than bacterial presence in the absence of inflammation. Modification of these risk factors could lead to new therapeutics that prevent the development of recurrent UTI.

Abstract
This study utilized magnetic resonance imaging (MRI) to monitor the real-time status of the urinary bladder in normal and diseased states following cyclophosphamide (CYP)-induced cystitis, and also examined the role of the phosphoinositide 3-kinase (PI3K) pathway in the regulation of urinary bladder hypertrophy in vivo. Our results showed that under MRI visualization the urinary bladder wall was significantly thickened at 8 h and 48 h post CYP injection. The intravesical volume of the urinary bladder was also markedly reduced. Treatment of the cystitis animals with a specific PI3K inhibitor LY294002 reduced cystitis-induced bladder wall thickening and enlarged the intravesical volumes. To confirm the MRI results, we performed H&E stain postmortem and examined the levels of type I collagen by real-time PCR and western blot. Inhibition of the PI3K in vivo reduced the levels of type I collagen mRNA and protein in the urinary bladder ultimately attenuating cystitis-induced bladder hypertrophy. The bladder mass calculated according to MRI data was consistent to the bladder weight measured ex vivo under each drug treatment. MRI results also showed that the urinary bladder from animals with cystitis demonstrated high magnetic signal intensity indicating considerable inflammation of the urinary bladder when compared to normal animals. This was confirmed by examination of the pro-inflammatory factors showing that interleukin (IL)-1α, IL-6 and tumor necrosis factor (TNF)α levels in the urinary bladder were increased with cystitis. Our results suggest that MRI can be a useful technique in tracing bladder anatomy and examining bladder hypertrophy in vivo during disease development and the PI3K pathway has a critical role in regulating bladder hypertrophy during cystitis.

Abstract
The Acute Cystitis Symptom Score - ACSS was originally developed in the Uzbek language and has demonstrated high reliability and validity. The study was aimed to develop a Russian version of the ACSS questionnaire and evaluate its psychometric properties. Translation and adaptation of the ACSS questionnaire containing 18 questions, 6 of them - for the typical symptoms of acute cystitis (AC), 4 - for the differential diagnosis; 3 - for the quality of life, and 5 - for the conditions that may affect the choice of treatment, were performed according to the recommendations developed by the Mapi Research Institute. Study involved 83 Russian-speaking women (mean age, 35.6 ±13.7 years); 38 (45.8%) patients were in the main group (patients with AC), and 45 (54.2%) - in the control group (without AC). Medical examination and appropriate treatment of the respondents were conducted in accordance with approved standards. After completing the course of therapy, 19 (50%) patients of the main group came for the control examination. There was statistically significant difference in the scores obtained in the two groups. Score profiles positively correlated with the results of laboratory tests (rho = 0.26-0.48). Cronbach's alpha for the Russian version of the questionnaire was 0.86 (95% CI, 0.81-0.91), area under the curve in the ROC analysis was 0.96. The results of testing the Russian version correspond to those of the original version. The Russian version of the ACSS questionnaire has high. reliability and validity, and can be recommended for clinical research and diagnosis of primary AC, and dynamic monitoring of the effectiveness of the treatment of the Russian-speaking population of patients.

Abstract
Objectives To investigate the urothelial dysfunction and inflammation of urinary bladder in patients with upper urinary tract (UUT) urolithiasis through the results of cystoscopic hydrodistension and immunohistochemistry study. Methods Ninety-one patients with UUT urolithiasis underwent cystoscopic hydrodistension before the stone surgery. Immunofluorescence staining of E-cadherin, zonula occludens-1 (ZO-1), tryptase (mast cell activation), and TUNEL (urothelial apoptosis) were performed in 42 patients with glomerulations after hydrodistension, 10 without glomerulations, and 10 controls. Results Of the 91 patients, 62 (68.2%) developed glomerulations after hydrodistension. Lower urinary tract symptoms (LUTS) were present in 53.8% patients, in whom significantly smaller maximal anesthetic bladder capacity (MBC) was noted. Patients with middle or lower 1/3 ureteral stones had a significantly higher glomerulation rate (88.6% vs. 55.4%, p<0.01) and lower MBC (618.4±167.6 vs. 701.2±158.4 ml, p = 0.027) than those with upper 1/3 ureteral or renal stones. Patients with UUT urolithiasis had significantly lower expression of E-cadherin (26.2±14.8 vs. 42.4±16.7) and ZO-1 (5.16±4.02 vs. 11.02±5.66); and higher suburothelial mast cell (13.3±6.8 vs. 1.3±1.2) and apoptotic cell (2.6±2.5 vs. 0.1±0.3) numbers than in controls (all p<0.01). Conclusions Urothelial dysfunction and increased suburothelial inflammation and apoptosis are highly prevalent in the bladders of UUT urolithiasis patients, indicating inflammation cross-talk between UUT and urinary bladder. Patients with UUT urolithiaisis concomitant with LUTS had a smaller MBC, which may explain the presence of irritative bladder symptoms.

Abstract
A 61-year-old female was referred to our hospital presenting with micturition pain and urinary frequency, which was not relieved by antibiotics. A cystoscopic examination revealed an erosion, reddening and edematous lesion in the left bladder wall. Pathological examination of transurethral biopsy showed erosion and cystitis. After biopsy, micturition pain and urinary frequency became worse. The pathological examination was reviewed, and the diagnosis of eosinophilic cystitis was made. Administration of a corticosteroid had provided a short duration of relief, but her symptoms recurred within the five weeks of treatment. Therefore, she was treated with a combination of corticosteroid and suplatast tolilate, followed by monotherapy with suplatast tolilate. The relief of the symptoms by suplatast to lilate therapy continued for five months. However, the symptoms relapsed. Re-administration of steroidal agents was considered, but the patient suffered from uncontrolled diabetes. Therefore, she was treated with a combination of suplatast tosilate, anti-allergic drugs and mirabegron. Fourteen months after treatment with suplatast tosilate, no disease progression was noted.

Abstract
OBJECTIVE To investigate the pathogenesis and therapy of hydronephrosis after hematopoietic stem cell transplantation (HSCT). METHODS From March 2004 to March 2014, 23 patients with hydronephrosis after HSCT were identified. With these data, the pathogenesis of hydronephrosis after HSCT were analyzed. According to the surgical intervention of hydronephrosis and ureteral dialation of ureteral stricture, the patients were divided into two groups, rank-sum test and exact probability test were used to evaluate whether there were significant differences in the time of hemorrhagic cystitis (HC) occurred, ureteritis and viremia. RESULTS HC, ureteritis, ureteral stenosis were all the causes of hydronephrosis after HSCT. In this study, 69.6% (16/23) of the patients suffered from HSCT were cured by conservative treatment, 30.4% (7/23) by surgical intervention, and 13.0% (3/23) by insertion DJ stent or nephrostomy.Of the patients [17.4% (4/23)] who suffered ureteral stenosis, 2 were cured after the balloon dialation of ureter, 1 needed DJ tube long-term insertion, and 1 was still followed-up. rank-sum test and exact probability test results showed that the patients who needed surgical intervention might suffer from HC later than other patients, and their incidences of viremia and ureteritis were higher, but the differences between the two groups were not statistically significant (P = 0.524, P = 0.169, and P = 0.124, respectively). The results also showed that the ureteritis incidences of the patients who suffered from ureteral stricture and needed ureteral dialation were higher than that of the other patients, and the difference between the two groups was statistically significant (P = 0.024). The patients who needed ureteral dialation suffered from HC later and their incidences of viremia was higher, but the differences between the two groups were not statistically significant (P = 0.73 and P = 0.27). CONCLUSION HC, ureteritis and ureteral stenosis may cause hydronephrosis after HSCT. Patients may treated by conservative treatment first. Patients who suffered from HC later, viremia and especially ureteritis should be paid more attention to, and be treated with surgical intervention when necessary. The patients with ureteral stenosis could be treated by ureteral balloon dialation.

Abstract
Bladder chronic inflammation is associated with the pathogenesis of bladder cancer; the underlying mechanism is unclear. The PT53 gene is an important anticancer gene in the body, which is suppressed in cancer. The ubiquitin E3 ligase A20 (A20) plays a role in regulating the activities of epithelial cells. This study was designed to investigate the correlation between A20 and the pathogenesis of bladder cancer. The biopsy tissues of human bladder cancer, bladder polypoid cystitis, and chronic inflammation were collected; the levels of A20 and p53 were analyzed by quantitative real-time RT-PCR, Western blotting, and immune precipitation. HEK293 cells were employed to test the role of overexpression of A20 in the suppression of the p53 gene in the cells. Fifty-six patients with bladder cancer, 48 patients with bladder polypoid cystitis, and 16 patients with bladder chronic inflammation were recruited into this study. Human bladder cancer tissue and the polypoid tissue showed high levels of A20, which had a positive correlation with the tumorigenesis in the bladder; 12 out of 46 (26.1%) patients with bladder polypoid cystitis were diagnosed as bladder cancer. A20 bound to p53 to form complexes in bladder cancer tissue and bladder polypoid tissue. The overexpression of A20 suppresses p53 protein levels in HEK293 cells. A20 has a positive correlation in the tumorigenesis of bladder polypoid disorders.

Abstract
Klinefelter syndrome is a clinical syndrome with a distinct 47, XXY karyotype. Patients are characterized by a tall eunuchoid stature, small testes, hypergonotrophic hypogonadism, gynecomastia, learning difficulties and infertility. These patients have also been found to have raised estrogen levels. We report a 16 year old boy with Klinefelter syndrome presenting to our institution with gross hematuria. Cystoscopy and biopsy revealed the diagnosis of pseudomembranous trigonitis. Immunohistochemical stains showed an increase in estrogen and progesterone receptors in the trigone area but not in the rest of the bladder. In view of the patient's mildly raised estrogen levels and the histological findings, we postulate that estrogen is the driver of the development of pseudomembranous trigonitis. This is the first reported case of pseudomembranous trigonitis seen in association with Klinefelter syndrome, and also the first case of pseudomembranous trigonitis occurring within the male adolescent age group.

Abstract
The article presents the results of morphological examination of bladder tissue reactions on the submucosal injection of mitomycin-C solution in different (0.1, 0.05, 0.025, and 0.0125%) concentrations. The experiments were conducted using dogs weighing 13-15 kg. Tissue sampling for histological evaluation were performed at 1, 2 and 3 hours, and on Day 7, 14, and 30. Maximum expression of the inflammatory response in the submucosa (edema, foci of lymphohistiocytic infiltration, increased microvascular lumen, diffuse leukocyte infiltration around the vessels of connective tissue between muscle fibers) was developed early after injection of 0.1% mitomycin-C, and it was minimal 3 hours after injection of 0.0125 % solution.

Abstract
Interstitial cystitis (IC), often referred to in combination with painful bladder syndrome, is a chronic inflammatory disease of the bladder. Current therapies primarily focus on replenishing urothelial glycosaminoglycan (GAG) layer using GAG analogs and managing pain with supportive therapies. However, the elusive etiology of IC and the lack of animal models to study the disease have been major hurdles developing more effective therapeutics. Previously, we showed an increased urinary concentration of antimicrobial peptide LL-37 in spina bifida patients and used LL-37 to develop a mouse model of cystitis that mimics important clinical findings of IC. Here we investigate (1) the molecular mechanism of LL-37 induced cystitis in cultured human urothelial cells and in mice, (2) the protective effects of GM-0111, a modified GAG, within the context of this mechanism, (3) the physiological and molecular markers that correlate with the severity of the inflammation, and (4) the protective effects of several GAGs using these biomarkers in our LL-37 induced cystitis model. We find that LL-37 quickly induces release of ATP and apoptosis in the urothelium. These changes can be inhibited by a chemically-modified GAG, GM-0111. Furthermore, we also find that GAG analogs provide varying degrees of protection against LL-37 challenge in mice. These findings suggest that GM-0111 and possibly GAG molecules prevent the development of cystitis by blocking the apoptosis and the concurrent release of ATP from the urothelium.

Abstract
From 2005 to 2013, 106 patients with post-coital cystitis underwent surgery. Of these, vaginal ectopia of urethral meatus was diagnosed in 19 (17.9%), and hypermobility of the distal urethra in 87 (82.1%). 28 (26.4%) women underwent the traditional plasty of distal urethra by O'Donnell method (group 1) and 78 (73.6%) patients underwent surgery using new method of extravaginal transposition of the urethra developed in our clinic (group 2). In group 1, satisfactory results were obtained in 23 (82.1%) patients, poor results--in 5 (17.9%) patients; in group 2, in 77 (98.7%) and 1 (1.3%) patients, respectively (p < 0.05). The disappointing results were attributable to the divergence of seams, reverse bias of urethra and recurrence of the disease. The use of method of extravaginal transposition of the urethra compared with a standard method allows to reduce the trauma of surgery, improve reliability of fixing the urethra, reducing the risk of its restriction and disease recurrence.
