Uncovering Surface Penetration by Enterococci From Urinary Tract Infection Patients.

IMPORTANCE: The relationship between Enterococcus faecalis vaginal colonization and urinary tract infections (UTIs) remains uncertain. OBJECTIVE: We aimed to evaluate the surface invasion capability of E faecalis isolates from patients with and without UTIs as a potential readout of pathogenicity. STUDY DESIGN: Participants were females from urogynecology clinics, comprising symptomatic UTI and asymptomatic non-UTI patients, categorized by the presence or absence of E faecalis-positive cultures identified via standard urine culture techniques. Vaginal and urine samples from patients were plated on enterococci selective medium, and E faecalis isolates detected in both cohorts were species specific identified using 16S rRNA sequencing. Clinical isolates were inoculated on semisolid media, and both external colonies and underneath colony prints formed by agar-penetrating enterococci were imaged. External growth and invasiveness were quantified by determining colony-forming units of the noninvading and agar-penetrating cells and compared with the E faecalis OG1RF. RESULTS: We selected E faecalis isolates from urine and vaginal samples of 4 patients with and 4 patients without UTIs. Assays demonstrated that most isolates formed similarly sized external colonies with comparable colony-forming unit. Surface invasion differed across patients and isolation sites compared with OG1RF. The vaginal isolate from UTI patient 1, who had the most recurrences, exhibited significantly greater agar-invading capacity compared with OG1RF. CONCLUSIONS: Our pilot study indicates that ex vivo invasion assays may unveil virulence traits in E faecalis from UTI patients. Enhanced enterococcal surface penetration could increase urogenital invasion risk. Further research is needed to correlate penetration with disease severity in a larger patient group.

No pelvic exam, no problem: patient satisfaction following the integration of comprehensive urogynecology telemedicine.

INTRODUCTION AND HYPOTHESIS: The COVID-19 pandemic revolutionized the practice of medicine, requiring rapid adoption of telemedicine. However, patient satisfaction has not been well characterized for telemedicine visits for a broad range of urogynecologic conditions. METHODS: We performed a cross-sectional survey study following a retrospective review of all urogynecologic telemedicine visits from March 1, 2020, to March 31, 2021, at a tertiary care center. The survey queried patient satisfaction using the Likert scale. Descriptive statistics and Fisher's exact analyses were performed. RESULTS: There were 256 telemedicine visits at our institution during the study period, and 88 patients (34% unadjusted response rate) completed the survey. The average age of study participants was 55 (SD 17; 24, 84) years old. The majority of patients were white (69%), lived within the five boroughs of NYC (81%), and had higher levels of education (72% with a bachelor's or professional degree). Most visits were for urinary complaints (68%), with those patients reporting greater fulfillment of urogynecologic needs compared to patients presenting with pelvic complaints (p = 0.02). There were no significant differences in satisfaction among other demographics (p > 0.05). Altogether, high satisfaction rates were noted for scheduling (99%), technology (90%), provider interaction (96%), fulfillment of personal needs (91%), and overall satisfaction (94%). CONCLUSIONS: We demonstrate high patient satisfaction for telemedicine visits in a tertiary urogynecology clinic for a variety of indications, with greater fulfillment of urogynecologic needs observed for those visits which may not necessitate an in-person exam (e.g., urinary complaint).

Characterizing Adverse Events Reporting for an Over-the-Counter Disposable Intravaginal Support Device for Stress Urinary Incontinence.

OBJECTIVES: In recent years, new intravaginal support devices for stress urinary incontinence have been introduced to the market. Although studies have demonstrated their safety and efficacy, few studies have examined adverse events attributed to their use. The objective of this study was to characterize reported adverse events for an over-the-counter intravaginal support device and determine whether further medical treatment was necessary to manage the adverse event. METHODS: We searched the Manufacturer and User Device Experience database from January 2015 to September 2020 for pertinent reported adverse events, which included the unique report key, event date, report date, event text descriptions, and resulting course of treatment. Per Manufacturer and User Device Experience database mandatory requirements, all reports were submitted by the manufacturer within 30 days of receiving the consumer's voluntary submission. RESULTS: A total of 257 reports were included for analysis. The most common reported adverse event was related to the string of the device, which broke with either removal or insertion of the device (230 of 257 [89.5%]). The majority of patients who required medical attention (133 of 257 [51.8%]) were evaluated and managed in the office setting (85 of 133 [63.9%]), whereas 37% (95 of 257) of patients were able to self-treat. CONCLUSIONS: Most complications attributed to device use were self-managed or managed in the outpatient setting. No emergent hospitalizations or deaths were attributed to their use, supporting their generally low-risk profile and high tolerability. Limitations of this review include the inability to decipher a denominator for these reported adverse events and the potential bias attributed to voluntary consumer reporting.

Long-term Device Outcomes of Mesh Implants in Pelvic Organ Prolapse Repairs.

OBJECTIVE: To evaluate the longer-term safety and reintervention outcomes of mesh implants in pelvic organ prolapse (POP) repairs. METHODS: We conducted a population-based cohort study of women undergoing POP repairs in inpatient and outpatient surgical settings between 2008 and 2016 in New York State. Multivariable logistic regression was used based on patient and procedural characteristics and hospital volume between mesh and nonmesh groups to obtain propensity scores for each individual. Long-term safety events and reinterventions were assessed using time-to-event analysis. RESULTS: We identified 54,194 women undergoing POP repairs (12,989 with mesh, and 41,205 without mesh). Mean age was 59.8 (±13.1) years, and median follow-up was 4.7 years (interquartile range, 2.4-6.8 years). In the propensity score-matched 12,284 pairs of women, POP repair with mesh was associated with a higher risk of reintervention when compared with POP repair without transvaginal mesh (hazard ratio 1.40, 95% CI 1.27-1.54, P<.001). The estimated risk of undergoing a reintervention at 5 years was 8.8% (95% CI 8.2-9.3%) in the mesh group and 6.3% (5.9-6.8%) in the nonmesh group. Among patients who had reinterventions, 18.5% of those operated with mesh had a reintervention related to mesh-related complications. CONCLUSION: Even though transvaginal mesh has been removed from the market, the risk of mesh complications did not diminish over time and these women warrant close follow-up. Continued surveillance of mesh in POP repairs is essential to ensure safety for the women who have already been implanted.

Is Something Missing From Antenatal Education? A Survey of Pregnant Women's Knowledge of Pelvic Floor Disorders.

OBJECTIVE: This study aimed to describe the knowledge on pelvic floor disorders among a cross section of pregnant women. STUDY DESIGN: This was an institutional review board-approved cross-sectional survey study of pregnant women with a gestational age of more than 18 weeks at a single tertiary care institution. Participants completed the validated 24-item Prolapse and Incontinence Knowledge Questionnaire, and responses were graded to determine a raw accuracy score (0-100%). Proficiency in the topic was defined as a score greater than 80% on the urinary scale and greater than 50% on the prolapse scale. RESULTS: Four hundred two women completed the survey. Mean ± SD raw accuracy in urinary incontinence was 66% ± 12%, and mean ± SD raw accuracy in pelvic organ prolapse was 41% ± 17%. These results were not significantly different among age or ethnic groups. Pregnant women were more likely to know that delivery could lead to incontinence (62%) than to pelvic organ prolapse (42%; P = 0.02), and 83% knew that pelvic floor exercises could prevent urinary incontinence. Proficiency was low among the population on both scales. CONCLUSIONS: Pregnant women have limited knowledge about pelvic floor dysfunction despite being at increased risk for these conditions during and after their pregnancies. This is an area where patient education and empowerment during routine prenatal care could improve.

Future Directions of Research and Care for Urinary Incontinence: Findings from the National Institute of Diabetes and Digestive and Kidney Diseases Summit on Urinary Incontinence Clinical Research in Women.

PURPOSE: Female urinary incontinence is prevalent, costly and morbid. Participants in a NIDDK (National Institute of Diabetes and Digestive and Kidney Diseases) sponsored summit reviewed findings from NIH (National Institutes of Health) funded clinical research on urinary incontinence in women and discussed the future of urinary incontinence research. MATERIALS AND METHODS: The NIDDK convened the Summit on Urinary Incontinence Clinical Research in Women on March 14, 2014. Participants representing a broad range of clinical expertise reviewed completed NIH sponsored urinary incontinence related studies, including results from community based epidemiological studies such as the BACH (Boston Area Community Health) Survey and from randomized clinical trials such as PRIDE (Program to Reduce Incontinence by Diet and Exercise), and studies conducted by the Pelvic Floor Disorders Network and the Urinary Incontinence Treatment Network. RESULTS: BACH Survey results improved our understanding of precursors, incidence, prevalence and natural history of urinary incontinence in a diverse group of women. The Pelvic Floor Disorders Network study found that anticholinergic medications and onabotulinumtoxinA are efficacious for treating urge urinary incontinence, and Burch colposuspension and retropubic mid urethral polypropylene slings are efficacious for decreasing stress urinary incontinence following pelvic organ prolapse surgery in women with potential stress urinary incontinence. The Urinary Incontinence Treatment Network study found that fascial slings were better than colposuspension, and that retropubic and transobturator mid urethral polypropylene slings were equivalent for stress urinary incontinence. In patients with stress urinary incontinence a preoperative urodynamic study was noninferior to basic office examinations for surgical outcome. The addition of behavioral intervention did not allow female patients to discontinue antimuscarinics for urge urinary incontinence. PRIDE showed that modest weight reductions significantly decreased urinary incontinence. CONCLUSIONS: Strategies for future research on urinary incontinence should include a focus on early disease, risk factor identification, better phenotyping, incorporation of new technologies, patient centered research and prevention.

Increased fluid intake is associated with bothersome bowel symptoms among women with urinary incontinence.

OBJECTIVES: To determine the association between the type and volume of fluid intake and bowel symptoms in women with urinary incontinence. We hypothesize that a lower volume of fluid intake would be associated with greater straining with bowel movements in women with urinary incontinence. METHODS: We performed a cross-sectional study of 256 women presenting with complaints of urinary incontinence from 2009 to 2010. Data on fluid intake, fluid intake behavior, urinary and bowel symptoms were collected using validated questionnaires. The relationship between quartiles of total daily fluid intake and bowel symptoms was analyzed. RESULTS: The behavior of restricting fluid intake was reported by 32% of the women. Increasing quartiles of total daily fluid intake was significantly associated with greater bother from straining with bowel movements (P = 0.04). Women with no bother from straining with bowel movements had significantly lower median daily fluid intake (2839 mL) than women with quite a bit of bother (3312 mL; P = 0.01). The association between the volume of fluid intake and straining with bowel movements persisted after controlling for age, body mass index, history of prolapse or incontinence surgery, and stage of prolapse (P < 0.05). There was no association between caffeinated fluid intake and any bowel symptom or between the behavior of restricting fluid intake and any bowel symptom. CONCLUSION: In women with urinary incontinence, higher volume of total fluid intake is reported by women with greater straining with bowel movements. The behavior of fluid restriction is not associated with bothersome bowel symptoms.

Lack of transient receptor potential vanilloid 1 channel modulates the development of neurogenic bladder dysfunction induced by cross-sensitization in afferent pathways.

BACKGROUND: Bladder pain of unknown etiology has been associated with co-morbid conditions and functional abnormalities in neighboring pelvic organs. Mechanisms underlying pain co-morbidities include cross-sensitization, which occurs predominantly via convergent neural pathways connecting distinct pelvic organs. Our previous results showed that colonic inflammation caused detrusor instability via activation of transient receptor potential vanilloid 1 (TRPV1) signaling pathways, therefore, we aimed to determine whether neurogenic bladder dysfunction can develop in the absence of TRPV1 receptors. METHODS: Adult male C57BL/6 wild-type (WT) and TRPV1-/- (knockout) mice were used in this study. Colonic inflammation was induced by intracolonic trinitrobenzene sulfonic acid (TNBS). The effects of transient colitis on abdominal sensitivity and function of the urinary bladder were evaluated by cystometry, contractility and relaxation of detrusor smooth muscle (DSM) in vitro to various stimuli, gene and protein expression of voltage-gated sodium channels in bladder sensory neurons, and pelvic responses to mechanical stimulation. RESULTS: Knockout of TRPV1 gene did not eliminate the development of cross-sensitization between the colon and urinary bladder. However, TRPV1-/- mice had prolonged intermicturition interval and increased number of non-voiding contractions at baseline followed by reduced urodynamic responses during active colitis. Contractility of DSM was up-regulated in response to KCl in TRPV1-/- mice with inflamed colon. Application of Rho-kinase inhibitor caused relaxation of DSM in WT but not in TRPV1-/- mice during colonic inflammation. TRPV1-/- mice demonstrated blunted effects of TNBS-induced colitis on expression and function of voltage-gated sodium channels in bladder sensory neurons, and delayed development of abdominal hypersensitivity upon colon-bladder cross-talk in genetically modified animals. CONCLUSIONS: The lack of TRPV1 receptors does not eliminate the development of cross-sensitization in the pelvis. However, the function of the urinary bladder significantly differs between WT and TRPV-/- mice especially upon development of colon-bladder cross-sensitization induced by transient colitis. Our results suggest that TRPV1 pathways may participate in the development of chronic pelvic pain co-morbidities in humans.

Utility of preoperative examination and magnetic resonance imaging for diagnosis of anterior vaginal wall masses.

INTRODUCTION AND HYPOTHESIS: The clinical evaluation of anterior vaginal wall masses can present a dilemma, as there are no well-defined pathways for diagnosis and management. Our objective was to evaluate the role and accuracy of preoperative exam and magnetic resonance imaging (MRI) for these masses. METHODS: We identified women with a mass using billing codes for 10 years. We compared data from the preoperative evaluation to postoperative pathology if available. RESULTS: Analysis after chart review on 47 women was performed. Of the 34 women who had surgery, 28 (82.4%) also underwent an MRI. MRI diagnosis was accurate in 22/28 women compared to histology, inconclusive in 4, and inaccurate in 2. Preoperative diagnosis, including exam, MRI, and cystourethroscopy, had a diagnostic accuracy of 94.1% compared to postoperative diagnosis. The positive predictive value of MRI alone was 91.7%. CONCLUSIONS: Preoperative diagnosis using exam, MRI, and cystourethroscopy have a high diagnostic accuracy for anterior vaginal wall masses.

Acute colonic inflammation triggers detrusor instability via activation of TRPV1 receptors in a rat model of pelvic organ cross-sensitization.

Chronic pelvic pain of unknown etiology is a common clinical condition and may develop as a result of cross-sensitization in the pelvis when pathological changes in one of the pelvic organs result in functional alterations in an adjacent structure. The aim of the current study was to compare transient receptor potential vanilloid 1 (TRPV1) activated pathways on detrusor contractility in vivo and in vitro using a rat model of pelvic organ cross-sensitization. Four groups of male Sprague-Dawley rats (N = 56) were included in the study. Animals received intracolonic saline (control), resiniferatoxin (RTX, TRPV1 agonist, 10(-7) M), 2,4,6-trinitrobenzene sulfonic acid (TNBS, colonic irritant), or double treatment (RTX followed by TNBS). Detrusor muscle contractility was assessed under in vitro and in vivo conditions. Intracolonic RTX increased the contractility of the isolated detrusor in response to electric field stimulation (EFS) by twofold (P ≤ 0.001) and enhanced the contractile response of the bladder smooth muscle to carbachol (CCh). Acute colonic inflammation reduced detrusor contractility upon application of CCh in vitro, decreased bladder capacity by 28.1% (P ≤ 0.001), and reduced micturition volume by 60% (P ≤ 0.001). These changes were accompanied by an increased number of nonmicturition contractions from 3.7 ± 0.7 to 15 ± 2.7 (N = 6 in both groups, P ≤ 0.001 vs. control). Desensitization of intracolonic TRPV1 receptors before the induction of acute colitis restored the response of isolated detrusor strips to CCh but not to EFS stimulation. Cystometric parameters were significantly improved in animals with double treatment and approximated the control values. Our data suggest that acute colonic inflammation triggers the occurrence of detrusor instability via activation of TRPV1-related pathways. Comparison of the results obtained under in vitro vs. in vivo conditions provides evidence that intact neural pathways are critical for the development of an overactive bladder resulting from pelvic organ cross talk.

Is pelvic pain associated with defecatory symptoms in women with pelvic organ prolapse?

OBJECTIVE: To investigate the significance of pelvic pain and its association with defecatory symptoms in women with pelvic organ prolapse (POP). STUDY DESIGN: This is a cross sectional study of 248 women with stage II POP or greater. Women were stratified into "pain" and "no-pain" groups based on their response to a question on the Pelvic Floor Distress Inventory short form. Associations between patient demographics, exam findings and responses to validated questionnaires were evaluated. RESULTS: In women with POP, defecatory symptoms are significantly more common in women with pelvic pain including straining with bowel movement (OR 2.4, 95% CI 1.3, 4.6), sense of incomplete emptying (OR 4.4, 95% CI 2.3, 8.2), pain with bowel movement (OR 5.3, 95% CI 1.2, 23.0) and splinting with bowel movement (OR 3.8, 95% CI 2.0, 7.5). CONCLUSION: In women with POP, the symptom of pelvic pain is associated with the presence of defecatory symptoms.

Clinical significance of obstructive defecatory symptoms in women with pelvic organ prolapse.

OBJECTIVE: To determine whether the presence of obstructive defecatory symptoms is associated with the site and severity of pelvic organ prolapse. METHODS: A cross-sectional study was performed of women with pelvic organ prolapse of grade 2 or greater who had completed a validated questionnaire that surveyed pelvic floor symptoms. Associations between patient characteristics, site and severity of prolapse, and obstructive bowel symptoms were investigated. RESULTS: Among 260 women with pelvic organ prolapse, women with posterior vaginal wall prolapse were more likely to report obstructive symptoms, such as incomplete emptying (41% vs 21%, P=0.003), straining at defecation (39% vs 19%, P=0.002), and splinting with defecation (36% vs 14%, P<0.001) compared with women without posterior vaginal wall prolapse. There was no significant association between any bowel symptom and increasing severity of prolapse. CONCLUSIONS: Obstructive bowel symptoms are significantly associated with the presence of posterior vaginal wall prolapse, but not with the severity of prolapse.
