Abstract
IMPORTANCE Mixed urinary incontinence (MUI) is common and can be challenging to manage. OBJECTIVES We present the protocol design and rationale of a trial comparing the efficacy of 2 procedures for the treatment of women with MUI refractory to oral treatment. The Midurethral sling versus Botulinum toxin A ( MUSA) trial compares the efficacy of intradetrusor injection of 100 U of onabotulinimtoxinA (an office-based procedure directed at the urgency component) versus midurethral sling (MUS) placement (a surgical procedure directed at the stress component). STUDY DESIGN The MUSA is a multicenter, randomized trial of women with MUI electing to undergo procedural treatment for MUI at 7 clinical centers in the NICHD Pelvic Floor Disorders Network. Participants are randomized to either onabotulinumtoxinA 100 U or MUS. OnabotulinimtoxinA recipients may receive an additional injection between 3 and 6 months. Participants may receive additional treatment (including crossover to the alternative study intervention) between 6 and 12 months. The primary outcome is change from baseline in Urogenital Distress Inventory (UDI) at 6 months. Secondary outcomes include change in UDI at 3 and 12 months, irritative and stress subscores of the UDI, urinary incontinence episodes, predictors of poor treatment response, quality of life and global impression outcomes, adverse events, use of additional treatments, and cost effectiveness. RESULTS Recruitment and randomization of 150 participants is complete and participants are currently in the follow-up phase. CONCLUSIONS This trial will provide information to guide care for women with MUI refractory to oral treatment who seek surgical treatment with either onabotulinumtoxinA or MUS.

Urinary microbiome community types associated with urinary incontinence severity in women. Am J Obstet Gynecol 2024; 230:344.e1-344.e20.

Abstract
BACKGROUND Urinary microbiome (urobiome) studies have previously reported on specific taxa and community differences in women with mixed urinary incontinence compared with controls. Therefore, a hypothesis was made that higher urinary and vaginal microbiome diversity would be associated with increased urinary incontinence severity. OBJECTIVE This study aimed to test whether specific urinary or vaginal microbiome community types are associated with urinary incontinence severity in a population of women with mixed urinary incontinence. STUDY DESIGN This planned secondary, cross-sectional analysis evaluated associations between the urinary and vaginal microbiomes and urinary incontinence severity in a subset of Effects of Surgical Treatment Enhanced With Exercise for Mixed Urinary Incontinence trial participants with urinary incontinence. Incontinence severity was measured using bladder diaries and Urinary Distress Inventory questionnaires collected at baseline. Catheterized urine samples and vaginal swabs were concurrently collected before treatment at baseline to assess the urinary and vaginal microbiomes. Of note, 16S rRNA V4 to V6 variable regions were sequenced, characterizing bacterial taxa to the genus level using the DADA2 pipeline and SILVA database. Using Dirichlet multinomial mixtures methods, samples were clustered into community types based on core taxa. Associations between community types and severity measures (Urinary Distress Inventory total scores, Urinary Distress Inventory subscale scores, and the number of urinary incontinence episodes [total, urgency, and stress] from the bladder diary) were evaluated using linear regression models adjusted for age and body mass index. In addition, alpha diversity measures for richness (total taxa numbers) and evenness (proportional distribution of taxa abundance) were analyzed for associations with urinary incontinence episodes and community type. RESULTS Overall, 6 urinary microbiome community types were identified, characterized by varying levels of common genera (Lactobacillus, Gardnerella, Prevotella, Tepidimonas, Acidovorax, Escherichia, and others). The analysis of urinary incontinence severity in 126 participants with mixed urinary incontinence identified a Lactobacillus-dominated reference group with the highest abundance of Lactobacillus (mean relative abundance of 76%). A community characterized by fewer Lactobacilli (mean relative abundance of 19%) and greater alpha diversity was associated with higher total urinary incontinence episodes (2.67 daily leaks; 95% confidence interval, 0.76-4.59; P=.007) and urgency urinary incontinence episodes (1.75 daily leaks; 95% confidence interval, 0.24-3.27; P=.02) than the reference group. No significant association was observed between community type and stress urinary incontinence episodes or Urogenital Distress Inventory total or subscores. The composition of vaginal community types and urinary community types were similar but composed of slightly different bacterial taxa. Vaginal community types were not associated with urinary incontinence severity, as measured by bladder diary or Urogenital Distress Inventory total and subscale scores. Alpha diversity indicated that greater sample richness was associated with more incontinence episodes (observed genera P=.01) in urine. Measures of evenness (Shannon and Pielou) were not associated with incontinence severity in the urinary or vaginal microbiomes. CONCLUSION In the urobiome of women with mixed urinary incontinence, a community type with fewer Lactobacilli and more diverse bacteria was associated with more severe urinary incontinence episodes (total and urgency) compared with a community type with high predominance of a single genus, Lactobacillus. Whether mixed urinary incontinence severity is due to lesser predominance of Lactobacillus, greater presence of other non-Lactobacillus genera, or the complement of bacteria consisting of urobiome community types remains to be determined.

The effect of 12-month postoperative weight change on outcomes following midurethral sling for stress urinary incontinence: a secondary analysis of the ESTEEM and TOMUS randomized trials. Int Urogynecol J 2023; 34:2809-2816.

Abstract
INTRODUCTION AND HYPOTHESIS Prior studies demonstrate mixed results on the impact of obesity on the success of midurethral slings (MUS), with little known about how postoperative weight change affects outcomes. We aimed to examine the effect of postoperative weight change on outcomes 12 months after MUS for stress urinary incontinence (SUI). METHODS This secondary analysis utilized data from two multicenter randomized trials of women undergoing MUS placement. Subjects were categorized into cohorts based on change in body weight at 12 months postoperatively: weight gain (≥5% increase); weight loss (≥5% decrease), and weight stable (<5% change). The primary outcome was SUI cure (no SUI episodes in a 3-day bladder diary). Patients with mixed urinary incontinence (MUI) were analyzed for changes in daily average urge incontinence (UUI) episodes in a 3-day diary. Penalized logistic regression assessed the impact of demographic and perioperative variables on the primary outcome. RESULTS Of the 918 women included, 635 (70%) were weight stable, 144 (15%) had weight gain, and 139 (15%) had weight loss. Patients in the weight loss cohort had a higher smoking rate and a higher baseline body mass index (SD 0.29, 2.7 respectively). All cohorts experienced high SUI cure rates ranging from 77 to 81%, with no significant difference in SUI cure between cohorts (p = 0.607). Of 372 subjects with MUI, the weight loss cohort had significantly greater improvement in UUI episodes. CONCLUSIONS Weight change at 12 months postoperatively did not significantly alter efficacy of MUS for treatment of SUI. Patients with MUI who lost ≥5% body weight had significantly greater improvement in UUI episodes.

A randomized controlled pilot trial to assess the effectiveness of a specially formulated food supplement and pelvic floor muscle training in women with stress-predominant urinary incontinence. BMC Womens Health 2023; 23:321. [PMID: 37340306 DOI: 10.1186/s12905-023-02476-z] [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: 10/18/2022] [Accepted: 06/10/2023] [Indexed: 06/22/2023] Open
Abstract
BACKGROUND Pelvic floor muscle training (PFMT) is the first-line treatment approach for stress urinary incontinence. Creatine and leucine have been shown to improve muscle function. Our aim was to assess the effectiveness of a food supplement and PFMT in women with stress-predominant urinary incontinence. METHODS Women with stress-predominant urinary incontinence were randomized in 1:1 ratio to receive daily oral supplementation for six weeks with either a food supplement (treatment group) or placebo (control group). Both groups were instructed to perform standardized daily PFMT. The primary outcome was the Urogenital Distress Inventory Short Form (UDI-6) score. Secondary outcomes were the Incontinence Impact Questionnaire (IIQ-7) score, Patient's Global Impression of Severity (PGI-S), and Biomechanical Integrity score (BI-score) measured by Vaginal Tactile Imager. To have a power of 80% and a significance level of 5% to detect a decrease of 16 points in the UDI-6 score, a sample size of 32 was needed, with 16 patients in each arm of our trial. RESULTS Sixteen women in the control group and sixteen in the treatment group completed the trial. Between-group analysis revealed no significant differences between the control and treatment group except for mean change (delta) in vaginal squeeze pressure [(cmH2O, mean ± SD), 5 ± 12 vs. 15 ± 15, P = 0.04] and mean change (delta) in PGI-S score [(mean ± SD), -0.2 ± 0.9 vs. -0.8 ± 0.8, P = 0.04]. Within-group analysis showed that UDI-6 and IIQ-7 scores improved significantly from baseline to six weeks in the treatment group but not in the control group [UDI-6 score (mean ± SD) 45 ± 21 vs. 29 ± 21, P = 0.02; 43 ± 18 vs. 33 ± 26, P = 0.22] [IIQ-7 score (mean ± SD) 50 ± 30 vs. 30 ± 21, P = 0.01; 48 ± 23 vs.40 ± 28, P = 0.36]. PGI-S scores only improved in the treatment group from baseline to six weeks after treatment [PGI-S score (mean ± SD) 3.1 ± 0.8 vs. 2.3 ± 0.8, P = 0.0001]. BI-score, on average, improved significantly in the treatment and control group as well [SD unit, mean, from - 1.06 to -0.58, P = 0.001; from - 0.66 to -0.42, P = 0.04]. CONCLUSIONS Women with stress-predominant urinary incontinence receiving a specially formulated supplement in addition to daily PFMT for six weeks had significantly improved urinary symptoms (decrease in UDI-6 score and IIQ-7) and BI-score compared to their baseline.

Abstract
ObjectiveAn approach for assessing the urinary microbiome is 16S rRNA gene sequencing, where analysis methods are rapidly evolving. This re-analysis of an existing dataset aimed to determine whether updated bioinformatic and statistical techniques affect clinical inferences.MethodsA prior study compared the urinary microbiome in 123 women with mixed urinary incontinence (MUI) and 84 controls. We obtained unprocessed sequencing data from multiple variable regions, processed operational taxonomic unit (OTU) tables from the original analysis, and de-identified clinical data. We re-processed sequencing data with DADA2 to generate amplicon sequence variant (ASV) tables. Taxa from ASV tables were compared to the original OTU tables; taxa from different variable regions after updated processing were also compared. Bayesian graphical compositional regression (BGCR) was used to test for associations between microbial compositions and clinical phenotypes (e.g., MUI versus control) while adjusting for clinical covariates. Several techniques were used to cluster samples into microbial communities. Multivariable regression was used to test for associations between microbial communities and MUI, again while adjusting for potentially confounding variables.ResultsOf taxa identified through updated bioinformatic processing, only 40% were identified originally, though taxa identified through both methods represented >99% of the sequencing data in terms of relative abundance. Different 16S rRNA gene regions resulted in different recovered taxa. With BGCR analysis, there was a low (33.7%) probability of an association between overall microbial compositions and clinical phenotype. However, when microbial data are clustered into bacterial communities, we confirmed that bacterial communities are associated with MUI. Contrary to the originally published analysis, we did not identify different associations by age group, which may be due to the incorporation of different covariates in statistical models.ConclusionsUpdated bioinformatic processing techniques recover different taxa compared to earlier techniques, though most of these differences exist in low abundance taxa that occupy a small proportion of the overall microbiome. While overall microbial compositions are not associated with MUI, we confirmed associations between certain communities of bacteria and MUI. Incorporation of several covariates that are associated with the urinary microbiome improved inferences when assessing for associations between bacterial communities and MUI in multivariable models.

Abstract
CONTEXT Female lower urinary tract symptoms (LUTS) are a common presentation in urological practice. Thus far, only a limited number of female LUTS conditions have been included in the European Association of Urology (EAU) guidelines compendium. The new non-neurogenic female LUTS guideline expands the remit to include these symptoms and conditions. OBJECTIVE To summarise the diagnostic section of the non-neurogenic female LUTS guideline and the management of female overactive bladder (OAB), stress urinary incontinence (SUI), and mixed urinary incontinence (MUI). EVIDENCE ACQUISITION New literature searches were carried out in September 2021 and evidence synthesis was conducted using the modified GRADE criteria as outlined for all EAU guidelines. A new systematic review (SR) on OAB was carried out by the panel for the purposes of this guideline. EVIDENCE SYNTHESIS The important considerations for informing guideline recommendations are presented, along with a summary of all the guideline recommendations. CONCLUSIONS Non-neurogenic female LUTS are an important cause of urological dysfunction. Initial evaluation, diagnosis, and management should be carried out in a structured and logical fashion based on the best available evidence. This guideline serves to present this evidence to health care providers in an easily accessible and digestible format. PATIENT SUMMARY This report summarises the main recommendations from the European Association of Urology guideline on symptoms and diseases of the female lower urinary tract (bladder and urethra) not associated with neurological disease. We cover recommendations related to diagnosis of these conditions, as well as the treatment of overactive bladder, stress urinary incontinence, and mixed urinary incontinence.

Abstract
BACKGROUND The urogenital microbiome is associated with urgency and mixed urinary incontinence symptoms and differential treatment responses to pharmacotherapy for urgency urinary incontinence. OBJECTIVE This study aimed to describe whether the preoperative urinary and vaginal microbiomes were associated with surgical treatment responses at 12 months after a midurethral sling operation in women with mixed urinary incontinence. STUDY DESIGN This cohort study compared the preoperative microbiome compositions of urine and vaginal samples from a subset of women undergoing a midurethral sling operation in the Effects of Surgical Treatment Enhanced With Exercise for Mixed Urinary Incontinence trial (NCT01959347) and compared the microbiota in women who were surgical responders vs surgical nonresponders. Twelve-month objective response was defined as a ≥70% reduction from baseline urinary incontinence episodes on a 3-day diary. Subjective response was defined as a change from baseline in the Urogenital Distress Inventory scores. Bacterial abundance and beta diversity were assessed using 16S ribosomal RNA sequencing. The primary differential abundance analysis described predominant bacterial operational taxonomic units associated with responders vs nonresponders using unadjusted and age-adjusted linear models. RESULTS Objective nonresponders (n=28) compared with responders (n=72) were older (58.5±10.7 vs 51.6±10.2 years) and more likely postmenopausal without hormone use (odds ratio, 6.4; 95% confidence interval, 1.8-22.6). Vaginal and urinary microbiota beta diversities were associated with age (P<.05) for both responders and nonresponders. Overall, predominant operational taxonomic units (genera) were Lactobacillus, Gardnerella, Tepidimonas, Escherichia, Streptococcus, and Prevotella. Operational taxonomic units from baseline urine samples were not significantly associated (P threshold=.05) with surgical treatment responses. A greater abundance of baseline vaginal Lactobacillus was associated with an objective response (P=.04) and Prevotella with an objective nonresponse (P=.01). Adjusting for age, only a greater abundance of baseline vaginal Prevotella was associated with an objective nonresponse (P=.01). Moreover, less abundant vaginal operational taxonomic units were associated with objective and subjective responses and persistent urinary incontinence symptoms (P<.05). CONCLUSION Women meeting a 70% reduction of urinary incontinence treatment episodes (objective responders) had greater vaginal Lactobacillus at the time of the surgical procedure; however, controlling for age diminished this association. Women not meeting a 70% reduction of urinary incontinence episodes 1 year after a midurethral sling operation had greater vaginal Prevotella at the time of the midurethral sling operation. Further research is needed to determine whether therapy altering the vaginal microbiome may impact surgical treatment responses in women with mixed urinary incontinence.

Abstract
BACKGROUND Urinary incontinence is prevalent among women, and it has a substantial economic impact. Mixed urinary incontinence, with both stress and urgency urinary incontinence symptoms, has a greater adverse impact on quality of life and is more complex to treat than either stress or urgency urinary incontinence alone. Studies evaluating the cost-effectiveness of treating both the stress and urgency urinary incontinence components simultaneously are lacking. OBJECTIVE Cost-effectiveness was assessed between perioperative behavioral and pelvic floor muscle therapies combined with midurethral sling surgery and midurethral sling surgery alone for the treatment of women with mixed urinary incontinence. The impact of baseline severe urgency urinary incontinence symptoms on cost-effectiveness was assessed. STUDY DESIGN This prospective economic evaluation was performed concurrently with the Effects of Surgical Treatment Enhanced with Exercise for Mixed Urinary Incontinence randomized trial that was conducted from October 2013 to April 2016. Participants included 480 women with moderate-to-severe stress and urgency urinary incontinence symptoms and at least 1 stress urinary incontinence episode and 1 urgency urinary incontinence episode on a 3-day bladder diary. The primary within-trial analysis was from the healthcare sector and societal perspectives, with a 1-year time horizon. Costs were in 2019 US dollars. Effectiveness was measured in quality-adjusted life-years and reductions in urinary incontinence episodes per day. Incremental cost-effectiveness ratios of combined treatment vs midurethral sling surgery alone were calculated, and cost-effectiveness acceptability curves were generated. Analysis was performed for the overall study population and subgroup of women with Urogenital Distress Inventory irritative scores of ≥50th percentile. RESULTS The costs for combined treatment were higher than the cost for midurethral sling surgery alone from both the healthcare sector perspective ($5100 [95% confidence interval, $5000-$5190] vs $4470 [95% confidence interval, $4330-$4620]; P<.01) and the societal perspective ($9260 [95% confidence interval, $8590-$9940] vs $8090 [95% confidence interval, $7630-$8560]; P<.01). There was no difference between combined treatment and midurethral sling surgery alone in quality-adjusted life-years (0.87 [95% confidence interval, 0.86-0.89] vs 0.87 [95% confidence interval, 0.86-0.89]; P=.90) or mean reduction in urinary incontinence episodes per day (-4.76 [95% confidence interval, -4.51 to 5.00] vs -4.50 [95% confidence interval, -4.25 to 4.75]; P=.13). When evaluating the overall study population, from both the healthcare sector and societal perspectives, midurethral sling surgery alone was superior to combined treatment. The probability that combined treatment is cost-effective compared with midurethral sling surgery alone is ≤28% from the healthcare sector and ≤19% from the societal perspectives for a willingness-to-pay value of ≤$150,000 per quality-adjusted life-years. For women with baseline Urogenital Distress Inventory irritative scores of ≥50th percentile, combined treatment was cost-effective compared with midurethral sling surgery alone from both the healthcare sector and societal perspectives. The probability that combined treatment is cost-effective compared with midurethral sling surgery alone for this subgroup is ≥90% from both the healthcare sector and societal perspectives, at a willingness-to-pay value of ≥$150,000 per quality-adjusted life-years. CONCLUSION Overall, perioperative behavioral and pelvic floor muscle therapies combined with midurethral sling surgery was not cost-effective compared with midurethral sling surgery alone for the treatment of women with mixed urinary incontinence. However, combined treatment was of good value compared with midurethral sling surgery alone for women with baseline severe urgency urinary incontinence symptoms.

Characteristics Associated With Treatment Failure 1 Year After Midurethral Sling in Women With Mixed Urinary Incontinence. Obstet Gynecol 2021; 138:199-207. [PMID: 34237755 PMCID: PMC10184494 DOI: 10.1097/aog.0000000000004444] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Accepted: 04/15/2021] [Indexed: 01/11/2023]
Abstract
OBJECTIVE To evaluate characteristics associated with treatment failure 1 year after midurethral sling in women with mixed urinary incontinence. METHODS Four-hundred three women who participated in a randomized trial that compared midurethral sling and behavioral and pelvic floor muscle therapy (combined group) compared with midurethral sling alone for mixed incontinence with 1-year follow-up data were eligible for this planned secondary analysis. Overall treatment failure was defined as meeting criteria for subjective or objective failure or both. Subjective failure was defined as not meeting the minimal clinical important difference for improvement on the UDI (Urogenital Distress Inventory) total score (26.1 points). Objective failure was defined as not achieving 70% improvement on mean incontinence episodes of any type per day or having undergone any additional treatment for persistent urinary symptoms at 12 months postoperative. Logistic regression models for treatment failure were constructed. Independent variables included site and treatment group, and clinical and demographic variables based on bivariate comparisons (P<.2). Treatment group interaction effects were evaluated. RESULTS One hundred twelve of 379 (29.6%) women had overall treatment failure, with 56 of 379 (14.7%) undergoing additional treatment but only two needing intervention for stress incontinence. Previous overactive bladder (OAB) medication (unadjusted odds ratio [OR] 2.19, adjusted odds ratio [aOR] 1.96, 95% CI 1.17-3.31); detrusor overactivity on cystometrogram (OR 2.25, aOR 2.82, 95% CI 1.60-4.97); and higher volume at first urge (OR 1.03, aOR 1.04, 95% CI 1.01-1.07) were associated with overall failure. Worse UDI-urgency scores were associated with failure, with an added interaction effect in the midurethral sling-alone group. CONCLUSIONS Certain clinical and urodynamic variables are associated with treatment failure after midurethral sling in women with mixed urinary incontinence. Women with more severe urgency symptoms at baseline may benefit from perioperative behavioral and pelvic floor muscle therapy combined with midurethral sling. Overall, the need for additional urinary treatment was low and primarily for OAB. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov, NCT01959347.

METHODS Four hundred three women who participated in a randomized trial that compared midurethral sling and behavioral and pelvic floor muscle therapy (combined group) against midurethral sling alone for mixed incontinence with 1 year of follow-up data were eligible for this planned secondary analysis. Overall treatment failure was defined as meeting criteria for subjective failure, objective failure, or both. Subjective failure was defined as not meeting the minimal clinically important difference for improvement on the UDI (Urogenital Distress Inventory)-total score (26.1 points). Objective failure was not achieving 70% improvement on mean incontinence episodes of any type per day or having undergone any additional treatment for urinary symptoms at 12 months postoperative. Logistic regression models for treatment failure were constructed. Independent variables included site and treatment group, and clinical and demographic variables based on bivariate comparisons (P<.2). Treatment group interaction effects were evaluated. RESULTS Previous overactive bladder medication use (unadjusted odds ratio [OR] 2.19, adjusted odds ratio [aOR] 1.89, 95% CI 1.10-3.25), detrusor overactivity on cystometrogram (OR 2.25, aOR 2.72, 95% CI 1.53-4.84), body mass index (OR 1.29, aOR 1.27, 95% CI 1.03-1.57), and Valsalva leak point pressure less than 60 cm H2O (OR 1.96, aOR 3.13, 95% CI 1.65-5.94) were associated with overall failure. Worse UDI urgency scores were associated with failure in the midurethral sling-alone group. Sling type (retropubic vs transobturator) was not associated with failure. CONCLUSION Certain clinical and urodynamic variables are associated with treatment failure after midurethral sling among women with mixed urinary incontinence. Women with more severe urgency symptoms at baseline may benefit from perioperative behavioral and pelvic floor muscle therapy combined with midurethral sling. This information is helpful for counseling women with mixed incontinence who are considering surgery. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov, NCT01959347.

Defining the relationship between vaginal and urinary microbiomes. Am J Obstet Gynecol 2020; 222:154.e1-154.e10. [PMID: 31421123 DOI: 10.1016/j.ajog.2019.08.011] [Citation(s) in RCA: 58] [Impact Index Per Article: 14.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2019] [Revised: 07/24/2019] [Accepted: 08/02/2019] [Indexed: 12/23/2022]
Abstract
BACKGROUND Although the vaginal and urinary microbiomes have been increasingly well-characterized in health and disease, few have described the relationship between these neighboring environments. Elucidating this relationship has implications for understanding how manipulation of the vaginal microbiome may affect the urinary microbiome and treatment of common urinary conditions. OBJECTIVE To describe the relationship between urinary and vaginal microbiomes using 16S rRNA gene sequencing. We hypothesized that the composition of the urinary and vaginal microbiomes would be significantly associated, with similarities in predominant taxa. STUDY DESIGN This multicenter study collected vaginal swabs and catheterized urine samples from 186 women with mixed urinary incontinence enrolled in a parent study and 84 similarly aged controls. Investigators decided a priori that if vaginal and/or urinary microbiomes differed between continent and incontinent women, the groups would be analyzed separately; if similar, samples from continent and incontinent women would be pooled and analyzed together. A central laboratory sequenced variable regions 1-3 (v1-3) and characterized bacteria to the genus level. Operational taxonomic unit abundance was described for paired vaginal and urine samples. Pearson's correlation characterized the relationship between individual operational taxonomic units of paired samples. Canonical correlation analysis evaluated the association between clinical variables (including mixed urinary incontinence and control status) and vaginal and urinary operational taxonomic units, using the Canonical correlation analysis function in the Vegan package (R version 3.5). Linear discriminant analysis effect size was used to find taxa that discriminated between vaginal and urinary samples. RESULTS Urinary and vaginal samples were collected from 212 women (mean age 53±11 years) and results from 197 paired samples were available for analysis. As operational taxonomic units in mixed urinary incontinence and control samples were related in canonical correlation analysis and since taxa did not discriminate between mixed urinary incontinence or controls in either vagina or urine, mixed urinary incontinence and control samples were pooled for further analysis. Canonical correlation analysis of vaginal and urinary samples indicated that that 60 of the 100 most abundant operational taxonomic units in the samples largely overlapped. Lactobacillus was the most abundant genus in both urine and vagina (contributing on average 53% to an individual's urine sample and 64% to an individual's vaginal sample) (Pearson correlation r=0.53). Although less abundant than Lactobacillus, other bacteria with high Pearson correlation coefficients also commonly found in vagina and urine included: Gardnerella (r=0.70), Prevotella (r=0.64), and Ureaplasma (r=0.50). Linear discriminant analysis effect size analysis identified Tepidimonas and Flavobacterium as bacteria that distinguished the urinary environment for both mixed urinary incontinence and controls as these bacteria were absent in the vagina (Tepidimonas effect size 2.38, P<.001, Flavobacterium effect size 2.15, P<.001). Although Lactobacillus was the most abundant bacteria in both urine and vagina, it was more abundant in the vagina (linear discriminant analysis effect size effect size 2.72, P<.001). CONCLUSION Significant associations between vaginal and urinary microbiomes were demonstrated, with Lactobacillus being predominant in both urine and vagina. Abundance of other bacteria also correlated highly between the vagina and urine. This inter-relatedness has implications for studying manipulation of the urogenital microbiome in treating conditions such as urgency urinary incontinence and urinary tract infections.

Abstract
Urinary incontinence is a common bladder health problem that disproportionately affects women, especially midlife women. In the absence of alarming signs or symptoms, a step-wise evaluation aligned with patient treatment preferences is appropriate. Initial interventions can include simple behavior therapies, lifestyle modifications, and toileting habits. Systemic medication, surgery, and specialty treatment also can be offered.

Abstract
Importance Mixed urinary incontinence, including both stress and urgency incontinence, has adverse effects on a woman's quality of life. Studies evaluating treatments to simultaneously improve both components are lacking. Objective To determine whether combining behavioral and pelvic floor muscle therapy with midurethral sling is more effective than sling alone for improving mixed urinary incontinence symptoms. Design, Setting, and Participants Randomized clinical trial involving women 21 years or older with moderate or severe stress and urgency urinary incontinence symptoms for at least 3 months, and at least 1 stress and 1 urgency incontinence episode on a 3-day bladder diary. The trial was conducted across 9 sites in the United States, enrollment between October 2013 and April 2016; final follow-up October 2017. Interventions Behavioral and pelvic floor muscle therapy (included 1 preoperative and 5 postoperative sessions through 6 months) combined with midurethral sling (n = 209) vs sling alone (n = 207). Main Outcomes and Measures The primary outcome was change between baseline and 12 months in mixed incontinence symptoms measured by the Urogenital Distress Inventory (UDI) long form; range, 0 to 300 points; minimal clinically important difference, 35 points, with higher scores indicating worse symptoms. Results Among 480 women randomized (mean [SD] age, 54.0 years [10.7]), 464 were eligible and 416 (86.7%) had postbaseline outcome data and were included in primary analyses. The UDI score in the combined group significantly decreased from 178.0 points at baseline to 30.7 points at 12 months, adjusted mean change -128.1 points (95% CI, -146.5 to -109.8). The UDI score in the sling-only group significantly decreased from 176.8 to 34.5 points, adjusted mean change -114.7 points (95% CI, -133.3 to -96.2). The model-estimated between-group difference (-13.4 points; 95% CI, -25.9 to -1.0; P = .04) did not meet the minimal clinically important difference threshold. Related and unrelated serious adverse events occurred in 10.2% of the participants (8.7% combined and 11.8% sling only). Conclusions and Relevance Among women with mixed urinary incontinence, behavioral and pelvic floor muscle therapy combined with midurethral sling surgery compared with surgery alone resulted in a small statistically significant difference in urinary incontinence symptoms at 12 months that did not meet the prespecified threshold for clinical importance. Trial Registration ClinicalTrials.gov Identifier: NCT01959347.

Abstract
INTRODUCTION & HYPOTHESIS Previous studies have suggested that women with urinary incontinence have an altered urinary microbiome. We hypothesized that the microbiome in women with mixed urinary incontinence (MUI) differed from controls and tested this hypothesis using bacterial gene sequencing techniques. METHODS This multicenter study compared the urinary microbiome in women with MUI and similarly aged controls. Catheterized urine samples were obtained; v4-6 regions of the 16S rRNA gene were sequenced to identify bacteria. Bacterial predominance (> 50% of an individual's genera) was compared between MUI and controls. Bacterial sequences were categorized into "community types" using Dirichlet multinomial mixture (DMM) methods. Generalized linear mixed models predicted MUI/control status based on clinical characteristics and community type. Post-hoc analyses were performed in women < 51 and ≥ 51 years. Sample size estimates required 200 samples to detect a 20% difference in Lactobacillus predominance with P < 0.05. RESULTS Of 212 samples, 97.6% were analyzed (123 MUI/84 controls, mean age 53 ± 11 years). Overall Lactobacillus predominance did not differ between MUI and controls (45/123 = 36.6% vs. 36/84 = 42.9%, P = 0.36). DMM analyses revealed six community types; communities differed by age (P = 0.001). A High-Lactobacillus (89.2% Lactobacillus) community had a greater proportion of controls (19/84 = 22.6%, MUI 11/123 = 8.9%). Overall, bacterial community types did not differ in MUI and controls. However, post-hoc analysis of women < 51 years found that bacterial community types distinguished MUI from controls (P = 0.041); Moderate-Lactobacillus (aOR 7.78, CI 1.85-32.62) and Mixed (aOR 7.10, CI 1.32-38.10) community types were associated with MUI. Community types did not differentiate MUI and controls in women ≥ 51 years (P = 0.94). CONCLUSIONS Women with MUI and controls did not differ in overall Lactobacillus predominance. In younger women, urinary bacterial community types differentiated MUI from controls.

Abstract
AIMS The primary aim is to provide detailed rationale and methodology for the development and implementation of a perioperative behavioral/pelvic floor exercise research protocol for women who self-chose surgical intervention and who may or may not have been offered behavioral treatments initially. This protocol is part of the ESTEEM trial (Effects of Surgical Treatment Enhanced with Exercise for Mixed Urinary Incontinence Trial) which was designed to determine the effect of a combined surgical and perioperative behavioral/pelvic floor exercise intervention versus surgery alone on improving mixed urinary incontinence (MUI) and overactive bladder (OAB) symptoms. METHODS As part of a multi-site, prospective, randomized trial of women with MUI electing midurethral sling (MUS) surgical treatment, participants were randomized to a standardized perioperative behavioral/pelvic floor exercise intervention + MUS versus MUS alone. The specific behavioral intervention included: education on voiding habits, pelvic floor muscle training (PFMT), bladder training (BT), strategies to control urgency and reduce/prevent urinary symptoms, and monitoring/promoting adherence to behavioral recommendations. To ensure consistency across all eight research sites in the pelvic floor disorders network (PFDN), selective behavioral treatments sessions were audiotaped and audited for protocol adherence. RESULTS The behavioral intervention protocol includes individualization of interventions using an algorithm based on pelvic floor muscle (PFM) assessment, participant symptoms, and findings from the study visits. We present, here, the specific perioperative behavioral/pelvic floor exercise interventions administered by study interventionists. CONCLUSIONS This paper details a perioperative behavioral/pelvic floor exercise intervention research study protocol developed for women undergoing surgery for MUI.

Abstract
INTRODUCTION AND HYPOTHESIS We describe the rationale and methods of a study designed to compare vaginal and urinary microbiomes in women with mixed urinary incontinence (MUI) and similarly aged, asymptomatic controls. METHODS This paper delineates the methodology of a supplementary microbiome study nested in an ongoing randomized controlled trial comparing a standardized perioperative behavioral/pelvic floor exercise intervention plus midurethral sling versus midurethral sling alone for MUI. Women in the parent study had at least "moderate bother" from urgency and stress urinary incontinence symptoms (SUI) on validated questionnaire and confirmed MUI on bladder diary. Controls had no incontinence symptoms. All participants underwent vaginal and urine collection for DNA analysis and conventional urine culture. Standardized protocols were designed, and a central lab received samples for subsequent polymerase chain reaction (PCR) amplification and sequencing of the bacterial16S ribosomal RNA (rRNA) gene. The composition of bacterial communities will be determined by dual amplicon sequencing of variable regions 1-3 and 4-6 from vaginal and urine specimens to compare the microbiome of patients with controls. Sample-size estimates determined that 126 MUI and 84 control participants were sufficient to detect a 20 % difference in predominant urinary genera, with 80 % power and 0.05 significance level. RESULTS Specimen collection commenced January 2015 and finished April 2016. DNA was extracted and stored for subsequent evaluation. CONCLUSIONS Methods papers sharing information regarding development of genitourinary microbiome studies, particularly with control populations, are few. We describe the rigorous methodology developed for a novel urogenital microbiome study in women with MUI.

Abstract
INTRODUCTION AND HYPOTHESIS Urinary incontinence (UI) is very common and heterogeneous among women with limited knowledge of progression or prognosis. Evidence based on clinical epidemiology can help to better understand the natural history of UI. METHODS We examine the challenges of UI definition and its subtypes, its impact on quality of life and health-seeking behavior. We review the proposed pathophysiology of UI subtypes and known risk factors as they relate to our current knowledge of the disease state. Finally, we emphasize the role of epidemiology in the process of acquiring new insight, improving knowledge, and translating this information into clinical practice. RESULTS Stress UI is most common overall, but mixed UI is most prevalent in older women. The three UI subtypes have some common risk factors, and others that are unique, but there remains a significant gap in our understanding of how they develop. Although the pathophysiology of stress UI is somewhat understood, urgency UI remains mostly idiopathic, whereas mixed UI is the least studied and most complex subtype. Moreover, there exists limited information on the progression of symptoms over time, and disproportionate UI health-seeking behavior. We identify areas of exploration (e.g., epigenetics, urinary microbiome), and offer new insights into a better understanding of the relationship among the UI subtypes and to develop an integrated construct of UI natural history. CONCLUSION Future epidemiological strategies using longitudinal study designs could play a pivotal role in better elucidating the controversies in UI natural history and the pathophysiology of its subtypes leading to improved clinical care.
