Abstract
Electrofulguration (EF) of areas of chronic cystitis in women with antibiotic-recalcitrant recurrent urinary tract infections (RUTIs) can result in improvement of their urinary tract infections (UTIs). We compared urine culture (UC) findings in patients before and after EF, as well as how they vary with cystitis stage at the time of EF, to evaluate for persistent species. After obtaining institutional review board approval, we retrospectively reviewed a prospectively maintained database of EF patients for those with positive UC findings in the 3-6 months preceding EF. Patient pre-EF UC was then compared with first positive UC after EF prompted by a new symptomatic UTI episode, with the hypothesis that the same species will be identified before and after EF. Exclusion criteria included UC from outside institution, neurogenic bladder, and need for catheterization. Ninety-nine women with pre- or post-EF UC-recorded organisms met the study criteria. The median age was 65 years (interquartile range 64-74), with a median time to first positive culture following fulguration of 9.7 months. For 26 patients with positive cultures both pre- and post-EF, the same organism was present in both cultures in 73% of the patients, with predominantly Escherichia coli. EF was effective at reducing the rate of UTIs in this population. For women undergoing EF for antibiotic-recalcitrant RUTIs and associated chronic cystitis lesions, 73% of those with a UC obtained at the time of a first symptomatic recurrent UTI episode post-EF expressed the same organism as before EF. Further study is needed to better understand the evolution of the microbiome post-EF.IMPORTANCEAmong women who experience a recurrent urinary tract infection after a fulguration procedure on areas of chronic cystitis in their bladder, there are no data available on whether the bacterial species found in urine cultures are the same or different from those present before fulguration. By removing the inflamed surface layer of cystitis during fulguration, it is possible that the procedure unmasks deep-seated bacteria. The bacterial kingdom in the bladder wall of these chronically infected women may be different from what is expressed sporadically in urine cultures. Confirming prior studies, we found that fulguration in women with antibiotic-recalcitrant recurrent urinary tract infections and cystitis lesions was effective at reducing the rate of urinary tract infections. At the time of a first symptomatic recurrent UTI episode post-fulguration, 73% expressed the same organism in urine culture as before fulguration. Further study is needed to better understand the evolution of the microbiome post-EF. This article evaluates persistent infections after electrofulguration of areas with chronic cystitis in post-menopausal women with antibiotic-recalcitrant recurrent urinary tract infections. Pre-fulguration urine cultures were compared with the first positive urine culture prompted by a new symptomatic UTI episode after electrofulguration, with the hypothesis that the same species will be identified before and after the fulguration procedure. Electrofulguration was effective at reducing the rate of UTIs in this population. However, 73% of those with a urine culture obtained at the time of a first symptomatic recurrent UTI episode post-electrofulguration expressed the same organism (predominantly Escherichia coli) as before the fulguration procedure. Further study is needed to better understand the evolution of the microbiome after electrofulguration.

Abstract
INTRODUCTION To quantify and compare recurrent urinary tract infection costs between 1 year before and 1 year after electrofulguration. METHODS Following IRB approval, a well-characterized cohort of non-neurogenic women with >3 symptomatic urinary tract infections (UTIs)/year, a negative upper and lower urinary tract evaluation, and inflammatory bladder lesions (cystitis) on office cystoscopy who underwent fulguration of these lesions was analyzed. Cost of visits, imaging, labs, and medications were summed for 1-year pre- and post-fulguration using the Medicare Physician Fee Schedule, local pharmacy pricing, and institutional expenses. Before fulguration, all patients underwent clinic visit, noninvasive flow study, and flexible cystoscopy, and post-fulguration, 6-week follow-up visit and 6-month cystoscopy. RESULTS Ninety-three women met study criteria (mean age 64), with 100% 1-year follow-up. Before fulguration, 73% of patients used daily antibiotic suppression, 6% self-start antibiotics, and 5% postcoital prophylaxis. Some also used vaginal estrogens (17%), urinary analgesics (13%), and cranberry or d-mannose supplements (7%). At 1 year post-fulguration, 82% had 0-1 infections and no cystoscopy evidence of cystitis, while 14% required additional fulguration for new cystitis sites and recurrent infections. Patients had on average 0.7 infections in the 1-year post-fulguration, which was significantly lower than pre-fulguration (p < 0.05). Mean 1-year pre-fulguration cost was $1328 (median $1071, range $291-$5564). Mean 1-year post-fulguration cost was $617 (median $467, range $275-$4580). On average, post-fulguration costs were $710 lower than pre-EF (p < 0.05). CONCLUSION For women with antibiotic-refractory recurrent urinary tract infections and cystoscopy evidence of cystitis, fulguration was associated with a significant reduction in UTI-related costs in the 1-year post-fulguration.

Abstract
Background Antibiotic-recalcitrant recurrent urinary tract infection (rUTI) is has become increasingly observed in postmenopausal women. Therefore, when standard antibiotic therapies have failed, some elect electrofulguration (EF) of areas of chronic cystitis when detected on office cystoscopy. EF is thought to remove tissue-resident bacteria that have been previously detected in the bladder walls of postmenopausal women with rUTI. We hypothesized that increased bladder bacterial burden may be associated with incomplete rUTI resolution following EF. Methods Following IRB approval, bladder biopsies were obtained from 34 consenting menopausal women electing EF for the advanced management of rUTI. 16S rRNA FISH was performed using both universal and Escherichia probes and tissue-resident bacterial load was quantified. Time to UTI relapse after EF was recorded during a six-month follow-up period and the association of bladder bacterial burden and clinical covariates with UTI relapse was assessed. Results We observed bladder-resident Escherichia in 52% of all participants and in 92% of participants with recent E. coli UTI. Time-to-relapse analysis revealed that women with high bladder bacterial burden as detected by the universal probe had a significantly ( p =0.035) higher risk of UTI within six months of EF (HR=3.15, 95% CI: 1.09-9.11). Interestingly, bladder-resident Escherichia was not significantly associated ( p =0.26) with a higher risk of UTI relapse (HR= 2.14, 95% CI: 0.58-7.90). Conclusions We observed that total bladder bacterial burden was associated with a 3.1x increased risk of rUTI relapse within six months. Continued analysis of the relationship between bladder bacterial burden and rUTI outcomes may provide insight into the management of these challenging patients.

Abstract
INTRODUCTION A subset of interstitial cystitis/bladder pain syndrome (IC/BPS) patients experience recurrent urinary tract infection (rUTI) associated with symptom flares. Recurrent UTI subjects with associated IC/BPS were enrolled in the first North American early clinical experience trial evaluating a new sublingual UTI preventative vaccine, MV140. It has been shown that women with rUTI develop an imbalance in the T helper 1 and 2 (Th2 over-expression) in the bladder mucosa. Our hypothesis-generating secondary analysis will suggest that this infection subcategory of IC/BPS patients develop a similar imbalance of Th1-Th2 response type to bacteria present in their urinary microbiome, leading to a bladder hypersensitivity that responds to mucosal immune modulation. METHODS Female participants with ≥3 documented UTI/year underwent a 3-month vaccination treatment period with a 9-month efficacy period after completion of vaccine treatment (total 12 months). There were no exclusion criteria for subjects in relation to baseline urinary symptoms and/or discomfort/pain. Primary outcome was no UTI following vaccination. Secondary outcomes included change in UTI incidence, overall patient-reported subjective global assessment (SGA responder defined as moderately or markedly improved on 7-point scale), and safety. RESULTS Sixteen subjects with IC/BPS-related symptoms and rUTI (mean age 47; range 23-74 years; mean number of UTI episodes in previous year 6.1 +/- 4.2) were eligible to be included in the Health Canada-approved MV140 vaccine study for prevention of rUTI. All subjects completed the 3-month vaccination period. One subject was lost to follow-up after their 6-month visit. Six subjects were UTI-free, while all 16 subjects had a reduction in UTI episodes compared to the year pre-vaccination. The total post-vaccination reduction in UTI episodes compared to pre-vaccination was 80% (0.1 UTI/subject/month from 0.5 UTI/subject/month, respectively). At 12 months, 13 subjects (81%) were SGA responders (moderately or markedly improved), and the responders reported a reduction in IC/BPS symptoms, with 8 subjects reporting significant or almost complete resolution of their specific long-term bladder discomfort/pain and bothersome urinary frequency or urgency. Four subjects reported mild and self-limited adverse events during vaccination period, but none were related to MV140 vaccine. CONCLUSION Sublingual MV140 vaccine in IC/BPS patients with rUTI not only achieved UTI-free or reduced UTI incidence status but also, after approximately 9 months post vaccination, resolution of patients' long-term treatment-refractory IC/BPS symptoms. This suggests some cases of IC/BPS may be etiologically based on Th2-driven hypersensitivity to bacteria within or entering the urinary microbiome that responds to a vaccine whose mechanism of action is to normalize or balance the bladder Th1/Th2 mucosal immune system.

Abstract
Introduction We proceeded with an in-depth review of diet diaries for nutrient analysis from a cohort of women suffering from uncomplicated recurrent urinary tract infection (RUTI) to validate the accuracy of our current food diet record (FDR) form and evaluate possible domains of improvement. Materials and Methods As part of an IRB-approved study, this previously published cohort of NHANES-comparable women was analyzed for consistency of the nutrient intake over 3 days, the influence of the time between meals and urine pH, the effect of nutrient intake over interval time between meals, and seasonal and before/during the COVID-19 pandemic changes. Intrarater reliability for nutrient analysis and intrapatient variability for urine pH were computed to test for consistency. Results Intrarater reliability for diet analysis was 91% accurate for foods and beverage matching and nutrient analysis. Mean standard deviation of urine pH readings within study participants was 0.4 (95% CI: 0.4, 0.5). An association was noted between total calories and fat consumed at breakfast and an increase in time to lunch. Calories consumed were unaffected across seasons or during the COVID-19 pandemic. Water intake during summer was significantly lower than that during fall and winter (both, p < 0.001). The patients who reported drinking water had a significantly lower average urine pH than women who did not report drinking water (5.8 vs. 6.2; p = 0.026). Conclusion In this cohort of postmenopausal women with RUTIs, in-depth analysis of our current FDR findings led to several actionable items, which will improve our current food diet self-reporting process by our patients.

Abstract
Recurrent urinary tract infection (rUTI) severely impacts postmenopausal women. The lack of rapid and accurate diagnostic tools is a major obstacle in rUTI management as current gold standard methods have >24-h diagnostic windows. Work in animal models and limited human cohorts have identified robust inflammatory responses activated during UTI. Consequently, urinary inflammatory cytokines secreted during UTI may function as diagnostic biomarkers. This study aimed to identify urinary cytokines that could accurately diagnose UTI in a controlled cohort of postmenopausal women. Women passing study exclusion criteria were classified into no UTI and active rUTI groups, and urinary cytokine levels were measured by immunoassay. Pro-inflammatory cytokines IL-8, IL-18, IL-1β, and monocyte chemoattractant protein-1 were significantly elevated in the active rUTI group, and anti-inflammatory cytokines IL-13 and IL-4 were elevated in women without UTI. We evaluated cytokine diagnostic performance and found that an IL-8, prostaglandin E2, and IL-13 multivariable model had the lowest misclassification rate and highest sensitivity. Our data identify urinary IL-8, prostaglandin E2, and IL-13 as candidate biomarkers that may be useful in the development of immunoassay-based UTI diagnostics.

Abstract
OBJECTIVE Chronic trigonitis (CT) is usually diagnosed through cystoscopy which is invasive and expensive. Thus, an accurate non-invasive diagnostic method is necessary. The objective of this study is to determine the efficacy of transvaginal bladder ultrasound (TBU) for CT diagnosis. METHODS Between 2012 and 2021, 114 women (17-76 years old) with recurrent urinary tract infection (RUTI) and history of antibiotic resistance were evaluated with TBU by a single ultrasonographer. As a control group, TBU was performed in 25 age-matched women with no previous history of UTI, urological or gynecological conditions. All patients with RUTI had undergone a cystoscopy with biopsy for diagnostic confirmation at the time of trigone cauterization. RESULTS Thickening of trigone mucosa (>3 mm) was detected in all patients with RUTI and represented the most relevant criteria for trigonitis diagnosis on TBU. Other TBU findings in CT are: irregular and interrupted mucosa lining (96.4%), free debris in the urine (85.9%), increased blood flow at doppler (81.5%), mucosa shedding and tissue flaps. Biopsy showed CT with erosive pattern (58%) or non-keratinizing metaplasia (42%). Diagnostic agreement index between TBU and cystoscopy was 100%. In the control group, normal trigone mucosa is ultrasonographically regular, continuous, with thickness ≤3 mm and there is no debris in the urine. CONCLUSIONS TBU proved to be an efficient, inexpensive and minimally invasive method to diagnose CT. To our knowledge, this is the first article that reports the use of transvaginal ultrasound as an alternative method for diagnosing trigonitis.

Abstract
A global increase in older individuals creates an increasing demand to understand numerous healthcare challenges related to aging. This population is subject to changes in tissue physiology and the immune response network. Older individuals are particularly susceptible to infectious diseases, with one of the most common being urinary tract infections (UTIs). Postmenopausal and older women have the highest risk of recurrent UTIs (rUTIs); however, why rUTIs become more frequent after menopause and during old age is incompletely understood. This increased susceptibility and severity among older individuals may involve functional changes to the immune system with age. Aging also has substantial effects on the epithelium and the immune system that led to impaired protection against pathogens, yet heightened and prolonged inflammation. How the immune system and its responses to infection changes within the bladder mucosa during aging has largely remained poorly understood. In this review, we highlight our understanding of bladder innate and adaptive immunity and the impact of aging and hormones and hormone therapy on bladder epithelial homeostasis and immunity. In particular, we elaborate on how the cellular and molecular immune landscape within the bladder can be altered during aging as aged mice develop bladder tertiary lymphoid tissues (bTLT), which are absent in young mice leading to profound age-associated change to the immune landscape in bladders that might drive the significant increase in UTI susceptibility. Knowledge of host factors that prevent or promote infection can lead to targeted treatment and prevention regimens. This review also identifies unique host factors to consider in the older, female host for improving rUTI treatment and prevention by dissecting the age-associated alteration of the bladder mucosal immune system.

Abstract
INTRODUCTION AND OBJECTIVE Recurrent urinary tract infections (R-UTIs) have a negative impact on quality of life and contribute to antimicrobial resistance. Long-term antibiotic therapy is the main treatment alternative but, in some cases, this approach may not be accepted by the patient, is ineffective or poorly tolerated. In selected women, electrofulguration (EF) of trigonal lesions has been shown to reduce urinary tract infection (UTI) episodes. METHODS Between August 2006 and December 2017, 73 women with R-UTI had their data collected prospectively and analyzed. We evaluated the rate of UTIs during the initial 2 years of follow-up after fulguration based on symptoms and a positive urine culture. All patients failed with multiple antibiotic courses and were offered endoscopic electrofulguration of the entire trigonal and bladder neck mucosa with a rollerball probe. We present our long-term results using a strategy of complete fulguration of the trigone in women with R-UTIs. RESULTS The median age was 64 years (range: 17-76 years) and the median follow-up time after EF was 4.2 years (range: 2.5-14 years). Overall, 70 patients (96%) remained free of UTI episodes during the first year of follow-up, at 2 years of follow-up, 57, 53% remained infection-free. Currently, UTIs are typically sparse, mild, and caused by multisensitive bacteria. CONCLUSIONS Complete trigonal and bladder neck mucosal fulguration promoted a significant reduction of UTI episodes during the first 2 years of follow-up. Prospective controlled studies are needed to determine the role of EF in women with R-UTI.

Abstract
INTRODUCTION AND HYPOTHESIS To evaluate how women with uncomplicated antibiotic-recalcitrant recurrent urinary tract infections (RUTIs) and extensive inflammatory bladder lesions on office cystoscopy responded to electro-fulguration (EF) to eliminate these chronic bladder sites. METHODS After IRB approval, a retrospective study of non-neurogenic women with RUTIs, inflammatory lesions on cystoscopy, and who underwent EF was performed. Lesions were classified through a simplified staging system based on the extent of bladder wall involvement. Only those with extensive bladder wall involvement (stages 3 and 4) at the time of EF were analyzed in this report. Six months after EF, an office cystoscopy was performed, with endoscopic success defined as no lesions seen. The primary clinical outcome was number of symptomatic UTIs after EF, defined as cure (0/year), improvement (1-2/year), and failure (≥3/year). RESULTS From 2007 to 2019, a total of 57 women met the study criteria, 30 stage 3 and 27 stage 4. Nineteen (63%) were endoscopically successful in stage 3 and 11 (41%) in stage 4. Mean follow-up was 2.9 years (stage 3) and 3.1 years (stage 4). All had at least a 6-month UTI follow-up after the 6 months of office cystoscopy, with 15 patients cured, 37 improved, and 5 failed (all stage 4). CONCLUSIONS Although EF only resulted in 63% complete endoscopic resolution, the majority experienced a decrease in the frequency of UTIs, suggesting that EF can be durably effective even in women with very extensive cystitis lesions.

Reduced urothelial expression of uroplakin-IIIa in cystitis areas in bladders of postmenopausal women with recurrent urinary tract infections: pilot study. World J Urol 2022; 40:1723-1730. [PMID: 35665841 DOI: 10.1007/s00345-022-04050-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Accepted: 04/30/2022] [Indexed: 10/18/2022] Open
Abstract
PURPOSE To study human bladder biopsies to investigate urothelial response to UTI, expression of uroplakin, and urothelial response after healing from cystoscopy with electrofulguration (CEF) treatment for antibiotic-recalcitrant RUTI. METHODS Following IRB approval, cold cup bladder biopsies from "no cystitis" and "cystitis" regions were obtained from women with antibiotic-recalcitrant rUTI undergoing CEF under anesthesia. "No cystitis" and "cystitis" biopsies from 14 patients (5 had prior CEF, 9 naïve) were analyzed by immunofluorescence (IF) confocal microscopy using antibodies against uroplakin-IIIa. For an additional 6 patients (2 prior CEF, 4 naïve), only "cystitis" area biopsies were taken and analyzed. Cytokeratin 5 (marker for squamous metaplasia) staining was performed on 14 patients. RESULTS In healthy tissue, uroplakin-IIIa staining was observed as a contiguous line on the luminal surface of umbrella cells. In "cystitis" areas for 19/20 patients, there was either no uroplakin-IIIa staining observed or spotty (+) staining. The "cystitis" regions of all patients had less intense uroplakin-IIIa staining compared to the matched "no cystitis" area in the same patient. In patients post-CEF but requiring repeat EF for persistent RUTI lesions, healed areas served as control and in 3 of 7 patients no uroplakin-IIIa staining was observed. Squamous metaplasia was observed in 10 patients. CONCLUSION In bladders of postmenopausal women with antibiotic-recalcitrant RUTI, areas with visible cystitis expressed less uroplakin-IIIa, supporting the model of urothelial exfoliation in response to UTI.

Abstract
Purpose To assess patient reliance on various over-the-counter (OTC) modalities used for prevention of recurrent urinary tract infection (RUTI) after electrofulguration (EF). Patients and Methods Following IRB approval, qualifying women were offered a short survey over the phone by a medical researcher to collect information about their use of various OTC modalities for prophylaxis of RUTI. Data was compared between two cohorts, ≥70 years old and <70 years old, using chi-squared and Student’s t-tests. Results From a database of 324 patients, 163 accepted the interview. 17% (28/163) reported current use of cranberry supplements, 10% (16/163) D-mannose supplements, and 42% (69/163) another non-prescription modality for RUTI prophylaxis. The non-geriatric (<70 years old) cohort spent, on average, $80 less annually on cranberry/D-mannose supplements (P=0.043) than the geriatric cohort and were more likely to use non-prescription modalities for the prevention of UTI (52% vs 30%; P=0.0061). Individuals using D-mannose were also much more likely to purchase their product online compared to those using cranberry supplements (85% vs 56%). Across all modalities, the perceived benefit difference in reducing UTI/year ranged from a median of 0 for Pyridium® (phenazopyridine hydrochloride) to four for probiotics, with D-mannose and cranberry at two/year, and those increasing daily fluid consumption at 2.5 fewer UTI/year. Conclusion Continued use of non-prescription modalities for RUTI prophylaxis were common among women with an EF history, but varied based on age groups. Across both age cohorts, annual expenditure and perceived benefit also varied among different OTC prophylactic modalities. Awareness of type and method of OTC modality implementation by patients with RUTI is essential to aligning use with current field recommendations.

Abstract
Objective: Tamoxifen complicates management of conditions such as urinary tract infections (UTIs), urinary incontinence (UI), and/or pelvic organ prolapse (POP) that traditionally benefit from hormonal intake; thus, we reviewed our experience in managing these hormonally deprived women. Materials and Methods: After IRB approval, electronic medical records from women with current use or history of tamoxifen use and referred to a tertiary care center with female pelvic medicine and reconstructive surgery expertise for UTI, UI, and/or POP were reviewed. Results: From 2015 to 2020, 32 women treated with tamoxifen 10–40 mg for a median of 4 years were referred for UTIs (9), UI (10), symptomatic POP (8), or for a combination of these (5). Participants with UTI treated with antibiotics, prophylactic supplements, and/or electrofulguration had satisfactory response at median follow-up of 1 year (interquartile range [IQR]: 0.5–1). Ten of 15 women with UI chose intervention, with no self-reported UI recurrence at median follow-up of 2.5 years (IQR: 1–3). All but one participant with POP underwent vaginal or open/robotic mesh repairs, with satisfactory outcomes at median follow-up of 3 years (IQR: 2–7). Conclusions: The management of UTIs, UI, and POP in women on tamoxifen or unable to benefit from hormonal intake is challenging, but traditional interventions can be considered with satisfactory results.

Transl Androl Urol 2021; 10:3456-3464. [PMID: 34532270 PMCID: PMC8421815 DOI: 10.21037/tau-21-550] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Accepted: 07/27/2021] [Indexed: 11/12/2022] Open
Abstract
Background As one of the causes of urethral symptoms, female chronic posterior urethritis is a common and distressing disease; however, it is often neglected and misdiagnosed as overactive bladder (OAB) or interstitial cystitis/bladder pain syndrome (IC/BPS). Currently, little is known about the urothelium and lamina propria of the bladder neck and proximal urethra. Thus, identifying urethral lesions is necessary for the diagnosis and treatment of female chronic posterior urethritis. Transurethral electroresection is an effective and safe approach for treating female chronic posterior urethritis. This study sought to determine if urethral lesions are necessary for the diagnosis and treatment of female chronic posterior urethritis, and evaluate the efficacy and safety of the transurethral electroresection of mucosa and submucosa in treating female chronic posterior urethritis. Methods A single-center, retrospective, observational study was conducted at a teaching and referral hospital. A total of 147 female patients who had been diagnosed with chronic papillary urethritis underwent transurethral electroresection between 2015 and 2018. Each patient underwent a follow-up examination. A chart review was also performed. Results Patients had a mean age of 54 years (range, 23–82 years), and the average follow-up period was 54.8 months (range, 6–600 months). Urinary frequency and urgency (51.7%) were the most common clinical manifestations of chronic posterior urethritis. Forty-two-point two percent of patients had positive urine culture results, most commonly with Mycoplasma genitalium. The cystoscopic findings revealed that chronic posterior urethritis has tuft-like, pseudopodia-like, finger-like, and follicular-like polyps and villi, and a pebble-like appearance with mucosal hyperemia. The success rate of the transurethral electroresection was 88.6%, and patients showed no apparent or serious complications. Conclusions This study showed that female chronic posterior urethritis is a cause that contributes to LUT symptoms. Its characteristic cystoscopic appearance and biopsy play a vital role in its diagnosis. The transurethral electroresection of urethral lesions is simple, effective, and minimally invasive without any apparent complications.

Abstract
This study is designed to evaluate the histological effects of uropathogenic Escherichia coli (UPEC) infection in the urinary bladder of female rabbits and compare the differences between the dome and trigone. Bacterial cystitis was induced in 13 female rabbits by transurethral inoculation of UPEC into the urinary bladder. Eight animals served as controls. Urine samples were collected by catheterization and cultured for bacterial growth after 12 and 24 hours then every 48 hours. Infection was defined as ≥(1X105) colony-forming unit/ml of UPEC in the first two urine samples. Bladder dome and trigonal specimens were examined by light and scanning electron microscopy eight days after infection. There was a sustained increase in bacterial count, with urethral bleeding and rabbit weakness suggesting bladder colonization in the 10/13 study group (77%). Infection was not demonstrated in two animals and was spontaneously cleared in the third after 48 hours. No control animals developed an infection. In infected rabbits (n = 10), the dome showed inflammatory changes including the epithelial loss or thinning, inflammatory cell infiltration, and congested blood vessels compared to controls. The trigone showed a more pronounced inflammatory response than the dome. The presence of urinary bacterial growth, infection manifestations, and inflammatory changes that were more severe in the trigone than in the dome indicate successful bacterial inoculation and induction of cystitis. This animal model can be used for clinical trials on female cystitis. Our histological findings support a possible role of trigone in the pathogenesis of urinary tract infection.

Abstract
This work uses controlled human cohorts to investigate urinary prostaglandin E2, the product of cyclooxygenase-2, as both a diagnostic and prognostic biomarker of recurrent UTI postmenopausal women. Urinary tract infection (UTI) is one of the most common adult bacterial infections and exhibits high recurrence rates, especially in postmenopausal women. Studies in mouse models suggest that cyclooxygenase-2 (COX-2)–mediated inflammation sensitizes the bladder to recurrent UTI (rUTI). However, COX-2–mediated inflammation has not been robustly studied in human rUTI. We used human cohorts to assess urothelial COX-2 production and evaluate its product, PGE2, as a biomarker for rUTI in postmenopausal women. We found that the percentage of COX-2–positive cells was elevated in inflamed versus uninflamed bladder regions. We analyzed the performance of urinary PGE2 as a biomarker for rUTI in a controlled cohort of 92 postmenopausal women and PGE2 consistently outperformed all other tested clinical variables as a predictor of rUTI status. Furthermore, time-to-relapse analysis indicated that the risk of rUTI relapse was 3.6 times higher in women with above median urinary PGE2 levels than with below median levels. Taken together, these data suggest that urinary PGE2 may be a clinically useful diagnostic and prognostic biomarker for rUTI in postmenopausal women.

Abstract
OBJECTIVE The aim of the study was to report on the presentation and outcomes of vesicular cystitis (VC), a chronic cystitis exhibiting translucent bladder mucosal vesicles, among women with antibiotic-refractory recurrent urinary tract infections (RUTIs). METHODS An analysis of our Institutional Review Board-approved series on antibiotic-refractory RUTIs was performed, selecting for documented VC lesions on cystoscopy. All patients had RUTIs defined as ≥3 urinary tract infections/year with positive urine culture. All patients were extensively treated with antibiotics with no resolution of RUTIs and were offered electrofulguration (EF) of VC lesions under anesthesia as a last resort. All patients had a 6-month post-EF office cystoscopy documenting persistence or resolution of the lesions, and a clinical outcome assessment based on RUTI frequency. RESULTS Of 482 patients, 18 (3.7%) treated during 2011-2017 met the study criteria. VC was most commonly found over the dome/anterior wall (7/18, 38%) and as pancystitis (7/18, 38%). There was often concomitant cystitis cystica of the trigone (8/18, 44%). At post-EF cystoscopy, persistence of VC was noted in 10/18 (56%) patients; 6/18 (33%) underwent repeat EF and an additional 3/18 (17%) were retreated due to new lesions after initial resolution. Two (11%) patients required simple cystectomy and urinary diversion due to RUTIs refractory to all interventions. Within a median follow-up of 2.8 years after EF, clinical cure was observed in 5/18 (28%), improvement in 10/18 (56%), and failure in 3/18 (17%) patients. CONCLUSIONS Among women with antibiotic-refractory RUTIs, VC is an infrequent and persistent form of cystitis with a predilection for non-trigonal bladder surfaces, whose management is challenging.

Abstract
OBJECTIVE To evaluate the efficacy of repeat endoscopic electrofulguration in women with antibiotic-refractory, recurrent urinary tract infections (RUTIs) with persistent symptoms after 1 electrofulguration. METHODS An institutional review board-approved, prospectively maintained database of non-neurogenic women with RUTIs, persistent symptoms and endoscopic findings of bladder wall inflammation after 1 electrofulguration, and minimum 6 months follow-up was reviewed. Endoscopic success was defined as complete resolution of previous lesions without new lesions seen during office cystoscopy 6 months after second electrofulguration. Clinical success was defined as no urinary tract infections at last follow-up; improvement as 1-2 treated infections/year; and failure as ≥3 treated infections/year, daily antibiotic suppression, or another electrofulguration (third or fourth). RESULTS From 2006 to 2018, 58/70 (83%) women with median age 70 years and median follow-up 26 months were included, and 53/58 had endoscopic data 6 months postsecond electrofulguration. Endoscopic success was noted in 26 (49%), and 21/26 had <3 UTIs within the last year of follow-up, vs 2/27 (7%) with endoscopic failure (P = .001). Among those with clinical failure, 6/30 (20%) remained on suppressive antibiotics, 9/30 (30%) required intravenous antibiotic courses, and 2 proceeded to cystectomy. Of 24 women who underwent a third electrofulguration, 11/24 (46%) were clinically successful or improved at median 22 months follow-up. Urine cultures from the year of last follow-up revealed extended-spectrum beta lactamase producing strains (50%) and strains resistant to >3 antibiotics (43%). CONCLUSION Women with persistent RUTIs following 1 electrofulguration may benefit from a second or even third procedure.

Abstract
INTRODUCTION Treatment of recurrent Urinary tract infections (UTIs) has become challenging because of the dramatic increase in the rates of recurrent infection andof multidrug-resistant (MDR) infections. AREAS COVERED The authors review recurrent UTIs(rUTI) management in women. EXPERT OPINION Continuous or post-coital prophylaxis with low-dose antimicrobials or intermittent self-treatment has all been demonstrated to be effective in managing rUTIs in women. Intravaginal estrogen therapy , shows potential toward preventing rUTI. Oral vaccine Uro-Vaxom seems to reduce the number of UTIs. There is evidence that other therapies (e.g. cranberry, Methenamine hippurate, oral D-mannose) may decrease the number of symptomatic UTIs. The treatment of CRE-UTIs is focused on a colistin backbone. Carbapenems are considered first-line agents for UTIs caused by ESBL, but their use is associated with increased MDR. The usage of non-carbapenem for the treatment of ESBL UTIs is necessary. Cefepime, Piperacillin-Tazobactam, Ceftolozane-Tazobactam, and Ceftazidime-Avibactam are justified options. Oral therapy with Pivmecillinam, Fosfomycin, and Nitrofurantoin can be used against uncomplicated UTIs due to ESBL infection.

Abstract
Recent advances in the analysis of microbial communities colonizing the human body have identified a resident microbial community in the human urinary tract (UT). Compared to many other microbial niches, the human UT harbors a relatively low biomass. Studies have identified many genera and species that may constitute a core urinary microbiome. However, the contribution of the UT microbiome to urinary tract infection (UTI) and recurrent UTI (rUTI) pathobiology is not yet clearly understood. Evidence suggests that commensal species within the UT and urogenital tract (UGT) microbiomes, such as Lactobacillus crispatus, may act to protect against colonization with uropathogens. However, the mechanisms and fundamental biology of the urinary microbiome-host relationship are not understood. The ability to measure and characterize the urinary microbiome has been enabled through the development of next-generation sequencing and bioinformatic platforms that allow for the unbiased detection of resident microbial DNA. Translating technological advances into clinical insight will require further study of the microbial and genomic ecology of the urinary microbiome in both health and disease. Future diagnostic, prognostic, and therapeutic options for the management of UTI may soon incorporate efforts to measure, restore, and/or preserve the native, healthy ecology of the urinary microbiomes.
