RESUMEN

BACKGROUND: A variety of factors influence bladder health, including environmental factors, life experiences, biologic foundations, and coexistent medical conditions. A biologically diverse microbial community exists in the urine that is likely influenced by the microbial inhabitants of the vagina. The relationship between the genitourinary (GU) microbiome and self-perceived bladder health is unknown. OBJECTIVE: To longitudinally define the GU microbiome in women with self-percieved bladder health sampled across multiple time points over a year. STUDY DESIGN: Women with no reported lower urinary tract dysfunction or symptoms (LUTS) were recruited from six clinical sites and assessed every 6 weeks for 1 year. Voided urine and vaginal samples were longitudinally collected. Self-perceived bladder health was assessed with select items from the LURN comprehensive assessment of self-reported urinary symptoms (CASUS) tool. We defined four life phases as follows: young (18-34 years, nulliparous), midlife (35-45 years, menstruating), transitional (46-60 years, perimenopausal), mature (>60 years, not using vaginal and/or systemic hormone replacement therapy). DNA was extracted from samples, and the V4 region of the 16S rRNA gene was amplified with region-specific primers. The 16S rRNA sequencing on an Illumina NovaSeq. Microbial beta-diversity was calculated using DEICODE to identify microbial taxa that cluster in the samples. Longitudinal volatility analysis was performed using the gemelli plugin. Log-abundance ratios of microbial features were explored and visualized in Qurro. RESULTS: Fifty-four (N = 16 young, N = 16 midlife, N = 15 transitional, N = 7 mature) women were enrolled and provided baseline data. Most women in each life phase (93%-98%) continued to report self-perceived bladder health throughout the 1-year follow-up as assessed by CASUS items. Temporal-based microbial diversity of urinary and vaginal microbiome remained relatively stable over 1 year in all subjects. The GU microbiomes of mature women were distinct and microbially diverse from that of young, midlife, and transitional women, with genera of Gardnerella, Cupriavidus, and Dialister contributory to the microbial features of the mature microbiome. The mature GU microbiome was statistically different (p < 0.0001) from the midlife, transitional, and young microbiome for the log ratio of Gardnerella and Cupriavidus (in the numerator) and Lactobacillus (in the denominator) for voided samples and Gardnerella and Dialister (in the numerator) and Lactobacillus (in the denominator) for vaginal samples. Differences in the GU microbiome were also demonstrated via longitudinal beta-diversity between women developing urinary frequency as reported by CASUS responses or objectively on bladder diary compared to women without urinary frequency. CONCLUSION: In women with a self-perceived healthy bladder, the GU microbiome remained stable in all age groups over a 1 year period. Differences were seen with respect to life phase, where mature women were distinct from all other groups, and with respect to self-reported LUTS.

RESUMEN

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.

RESUMEN

INTRODUCTION AND HYPOTHESIS: The objective was to evaluate the stability of the urinary microbiome communities in women undergoing sacral neuromodulation (SNM) for urgency urinary incontinence (UUI). We hypothesized that clinical response to SNM therapy would be associated with changes in the urinary microbiome. METHODS: Women completed the Overactive Bladder Questionnaire Short-Form, the International Consultation on Incontinence Questionnaire Short Form, and the Female Sexual Function Index at baseline and 3 months post-SNM implantation. Transurethral urinary specimens were obtained for microbiome analysis at baseline and 3 months postoperatively. The V4 region of the 16S rRNA gene (515F-806R) was amplified with region-specific primers, and Amplicon Sequence Variants (ASVs) were identified with a closed-reference approach of taxonomic classification. Alpha-diversity was calculated using the phylogenetic (i.e., Faith's phylogenetic diversity) and nonphylogenetic metrics (i.e., Shannon diversity, and Pielou's evenness) using the QIIME2 plugin. Longitudinal paired volatility analysis was performed using the DEICODE and Gemelli plugin to account for host specificity across both time and space. RESULTS: Nineteen women who underwent SNM and provided both baseline and 3-month urine samples were included in this analysis. Women reported improvement in objective (number of UUI episodes) and subjective (symptom severity and health-related quality of life) measures. Ninety percent of the bacteria were classified as Bacteroidetes, Firmicutes, Proteobacteria, and Actinobacteria. No significant differences were observed in each subject's beta-diversity at 3 months compared with their baseline microbiome. CONCLUSIONS: Our descriptive pilot study of a cohort of women who had achieved objective and subjective improvements in UUI following SNM therapy demonstrates that the urinary microbiome remains relatively stable, despite variability amongst the cohort.

RESUMEN

OBJECTIVES: To investigate the histologic characteristics of vulvar tissues before and after completion of fractionated carbon dioxide (CO2 ) laser therapy (FxCO2) for vulvar lichen sclerosus (LS). The secondary objective was to assess subjective improvement in symptoms via the Skindex-16 questionnaire. METHODS: This prospective single-arm study was conducted from April 2021 to August 2022 at one academic medical center. Ten postmenopausal women with biopsy-proven LS planning FxCO2 laser treatment were enrolled. Exclusion criteria included prior transvaginal mesh for prolapse, topical corticosteroid use within 8 weeks, prior pelvic radiation, malignancy, active genital infection, or pregnancy. The vulvovaginal SmartXide2-V2-LR laser system fractionated CO2 laser (DEKA) was utilized to treat visually affected areas of vulvar and perianal LS with a single pass. Subjects underwent three treatments 4-6 weeks apart. Subjects completed the Skindex-16 questionnaire and had vulvar biopsy at baseline and at 4 weeks after completion of fractionated CO2 laser therapy. Blinded histologic slides were scored by one dermatopathologist (Michael A. Cardis) rating from 1 to 5 the degree of dermal sclerosis, inflammation, and epidermal atrophy. Change scores were calculated as the difference between pre- and post-treatment scores for each subject. RESULTS: The 10 subjects enrolled had a mean age of 61 and most were white, privately insured, and had a college/graduate-level education. Post-fractionated CO2 laser treatment vulvar biopsies showed significant improvement in sclerosis and epidermal atrophy compared with pretreatment baseline biopsy specimens (p < 0.05) with no statistically significant change found in inflammation score. Skindex-16 and FSFI scores showed a trend towards improvement (p > 0.05 for both). A statistically significant correlation was found between change in sclerosis and Skindex-16 symptoms scores with an average change of 21.4 units in Skindex-16 symptoms score for every one-point change in histologic sclerosis score (p = 0.03). CONCLUSIONS: In postmenopausal women with vulvar LS undergoing fractionated CO2 laser, symptomatic improvements correlated with histologic change in degree of sclerosis on vulvar biopsy. These results demonstrate FxCO2 laser therapy as a promising option for the treatment of LS and suggest that further studies should assess degree of sclerosis on histopathology.

RESUMEN

STUDY OBJECTIVE: To examine national trends among race and ethnicity and route of benign hysterectomy from 2007 to 2018. DESIGN: This is a retrospective analysis of the prospective National Surgical Quality Improvement Program cohort program. SETTING: This study included data from the National Surgical Quality Improvement Program database including data from the 2014 to 2018 targeted hysterectomy files. PATIENTS: Adult patients undergoing hysterectomy. INTERVENTIONS: None MEASUREMENTS AND MAIN RESULTS: Current Procedural Terminology codes identified women undergoing benign hysterectomy and perioperative data including race and ethnicity were obtained. To determine relative trends in hysterectomy among race and ethnicity cohorts (White, Black, Hispanic), we calculated the proportion of each procedure performed annually within each race and ethnicity group and compared it across groups. From 2007 to 2018, 269 794 hysterectomies were collected (190 154 White, 45 756 Black, and 33 884 Hispanic). From 2007 to 2018, rates of laparoscopic hysterectomy increased in all cohorts (30.2%-71.6% for White, 23.9%-58.5% for Black, 19.9%-64.0% for Hispanic; ptrend <0.01 for all). For each year from 2007 to 2018, the proportion of women undergoing open abdominal hysterectomy remained twice as high in Black Women compared with White women (33.1%-14.4%, p <.01). Data from the 2014 to 2018 targeted files showed Black and Hispanic women undergoing benign hysterectomy were generally younger, had larger uteri, were more likely to be current smokers, have diabetes and/or hypertension, have higher body mass index, and have undergone previous pelvic surgery (p ≤.01 for all). CONCLUSION: Compared with White women, Black and Hispanic women are less likely to undergo benign hysterectomy via a minimally invasive approach. Although larger uteri and comorbid conditions may attribute to higher rates of open abdominal hysterectomy, the higher prevalence of abdominal hysterectomy among younger Black and Hispanic women highlights potential racial disparities in women's health and access to care.

RESUMEN

OBJECTIVES: There are no data on current surgical practice patterns for benign total vaginal hysterectomy (TVH) despite recently published guidelines. The objective was to determine gynecologic surgeon practice patterns regarding TVH perioperative interventions and to assess adherence to clinical practice guidelines. METHODS: A survey to assess TVH practice patterns was distributed to gynecologic surgical society members for completion. The primary outcome was to compare adherence to practice guidelines between fellowship-trained and non-fellowship-trained gynecologic surgeons. Secondary outcomes included comparing adherence based on age, practice location, and hysterectomy volume. RESULTS: Of the 204 respondents, there were 163 (80%) fellowship-trained and 41 (20%) non-fellowship-trained gynecologic surgeons. Fellowship-trained surgeons were more likely than non-fellowship-trained surgeons to use vaginal packing (34% vs 15%, P = 0.028), which is contrary to the recommendations. No cohort followed the guideline recommending a circular cervicovaginal incision. Fellowship-trained surgeons also were more likely than non-fellowship-trained surgeons to use the clamp and suture technique for vessel ligation (88% vs 68%, P = 0.004); otherwise, there were no significant differences between cohorts for adherence to any of the other guidelines. Although fellowship-trained surgeons were adherent to fewer of the guidelines as compared with surgeons without fellowship training, both groups generally adhered to a majority of the clinical practice guidelines for benign TVH. CONCLUSIONS: This information demonstrates a need for the development of targeted education and interventions to increase the use of evidence-based clinical practice guidelines during TVH for both fellowship-trained and non-fellowship-trained gynecologic surgeons.

RESUMEN

BACKGROUND: Intraoperative evaluation of ureteral patency is often performed in gynecologic and urogynecologic surgery. Many agents are used to help assess the patency, each with its own associated cost, ease of use, and adverse reactions. Some agents, such as dextrose, are used as an instillation fluid to create a viscosity difference and aid the visualization of a ureteral jet. Others, such as oral phenazopyridine or the intravenous use of sodium fluorescein and indigo carmine, cause a color change of the urine to directly aid the visualization of ureteral jets. Recently, numerous studies have examined the efficacy and surgeon satisfaction of these agents. The studies have also emphasized certain options as associated with a lower cost. However, there have not been any cost studies comparing these agents. OBJECTIVE: To compare the cost-effectiveness of the following 4 agents that are commonly used in assessing ureteral patency intraoperatively: oral phenazopyridine, dextrose instillation, intravenous sodium fluorescein, and intravenous indigo carmine. STUDY DESIGN: We constructed a decision-analytic model to compare cystoscopy using oral phenazopyridine, dextrose instillation, intravenous sodium fluorescein, and intravenous indigo carmine. Failure to see efflux resulted in work-ups for ureteral obstruction. The probabilities were obtained from published studies, and the probability of successfully seeing efflux ranged from 0.92 with oral phenazopyridine to 0.99 with intravenous indigo carmine. The costs of the agents, adverse effects, and ureteral obstruction work-ups were obtained from the University of North Carolina at Chapel Hill Department of Pharmacy, the Healthcare Cost and Utilization Project 2016 database and the FAIR Health Consumer database. The cost of a ureteral obstruction work-up used in our model ranged from $9755 for intraoperative evaluation with retrograde pyelograms and stents to $29,034 for hospitalization. Our primary outcome was the incremental cost-effectiveness ratio per unnecessary work-up for ureteral obstruction avoided. Sensitivity analyses were performed to identify the key uncertainties. RESULTS: Oral phenazopyridine, followed by an intravenous agent if needed, had a mean cost of $110 per patient. Dextrose averaged $151 more per patient, with only a slight improvement in avoiding unnecessary ureteral obstruction work-ups and a higher cost associated with adverse reactions (incremental cost-effectiveness ratio, $62,000). Intravenous agents cost approximately $1000 more per patient and were less effective at preventing unnecessary work-ups. Sensitivity analyses did not identify any thresholds that would significantly change the outcomes. CONCLUSION: Our model suggests that oral phenazopyridine and dextrose instillation are the least expensive and the most effective agents to aid in the visualization of ureteral patency during intraoperative cystoscopy, although dextrose is associated with higher costs owing to a higher rate of adverse reactions (primarily urinary tract infections). Intravenous sodium fluorescein and indigo carmine are historically popular first-choice agents. However, they were found to be more expensive and less effective as primary agents in our model and should likely be reserved for use as secondary agents in the event that the visualization of ureteral jets is unclear with the initial use of phenazopyridine or dextrose.

RESUMEN

INTRODUCTION AND HYPOTHESIS: To conduct a multi-centered randomized trial evaluating stress urinary incontinence (SUI) treatment based on the Patient Global Impression of Improvement score after 4 weeks using a continence pessary (CP) or a disposable intravaginal continence device (DICD). The null hypothesis is no difference in treatment success between cohorts. METHODS: This parallel group, active treatment comparative effectiveness trial randomized women with SUI to either CP or DICD for 4 weeks in a 1:1 allocation ratio. Exclusion criteria included pregnancy, UTI, postmenopausal bleeding, neurogenic bladder, urinary retention, prolapse, contraindication to or prior treatment with CP/DICD, and prior SUI surgery. Assuming an 80% power, an alpha of 5% and 20% dropout, we needed 138 participants to detect 50% success with CP versus 25% with DICD. Due to slow enrollment, the study was stopped after 16 months with 50 participants enrolled. RESULTS: Of the 50 women enrolled, 25 (50%) were randomized to CP and 25 (50%) to DICD. Thirty-five of 50 (70%) completed a fitting, and 22/50 (44%) completed 4-week and 17/50 (34%) completed 6-month follow-up. Baseline characteristics were similar, and there was high treatment success in each cohort [80% (8/10) CP vs. 75% (9/12) DICD; p = 1.0]. DICD patients showed improvement on all questionnaires but had higher use of other therapies over 6 months. CP patients showed improvements except for lower sexual function scores at 4 weeks. No serious adverse events occurred. CONCLUSIONS: Most women fitted with a CP/DICD experienced treatment success after 4 weeks without serious adverse events.

RESUMEN

OBJECTIVE: Women consider preservation of sexual activity and improvement of sexual function as important goals after pelvic organ prolapse surgery. This systematic review aimed to compare sexual activity and function before and after prolapse surgery among specific approaches to pelvic organ prolapse surgery including native tissue repairs, transvaginal synthetic mesh, biologic grafts, and sacrocolpopexy. DATA SOURCES: MEDLINE, Embase, and ClinicalTrials.gov databases were searched from inception to March 2021. STUDY ELIGIBILITY CRITERIA: Prospective comparative cohort and randomized studies of pelvic organ prolapse surgeries were included that reported the following specific sexual function outcomes: baseline and postoperative sexual activity, dyspareunia, and validated sexual function questionnaire scores. Notably, the following 4 comparisons were made: transvaginal synthetic mesh vs native tissue repairs, sacrocolpopexy vs native tissue repairs, transvaginal synthetic mesh vs sacrocolpopexy, and biologic graft vs native tissue repairs. METHODS: Studies were double screened for inclusion and extracted for population characteristics, sexual function outcomes, and methodological quality. Evidence profiles were generated for each surgery comparison by grading quality of evidence for each outcome across studies using a modified Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. RESULTS: Screening of 3651 abstracts was performed and identified 77 original studies. The overall quality of evidence was moderate to high. There were 26 studies comparing transvaginal synthetic mesh with native tissue repairs, 5 comparing sacrocolpopexy with native tissue repairs, 5 comparing transvaginal synthetic mesh with sacrocolpopexy, and 7 comparing biologic graft with native tissue repairs. For transvaginal synthetic mesh vs native tissue repairs, no statistical differences were found in baseline or postoperative sexual activity, baseline or postoperative total dyspareunia, persistent dyspareunia, and de novo dyspareunia. Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire short form change scores were not different between transvaginal synthetic mesh and native tissue repairs (net difference, -0.3; 95% confidence interval, -1.4 to 0.8). For sacrocolpopexy vs native tissue repairs, baseline or postoperative sexual activity, baseline or postoperative total dyspareunia, de novo dyspareunia, and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire short form score differences were not different. For biologic graft vs native tissue repairs, baseline or postoperative sexual activity, baseline or postoperative total dyspareunia, and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire short form changes were also not different. For transvaginal synthetic mesh vs sacrocolpopexy, there was no difference in sexual activity and sexual function score change. Based on 2 studies, postoperative total dyspareunia was more common in transvaginal synthetic mesh than sacrocolpopexy (27.5% vs 12.2%; odds ratio, 2.72; 95% confidence interval, 1.33-5.58). The prevalence of postoperative dyspareunia was lower than preoperative dyspareunia after all surgery types. CONCLUSION: Sexual function comparisons are most robust between transvaginal synthetic mesh and native tissue repairs and show similar prevalence of sexual activity, de novo dyspareunia, and sexual function scores. Total dyspareunia is higher after transvaginal synthetic mesh than sacrocolpopexy. Although sexual function data are sparse in the other comparisons, no other differences in sexual activity, dyspareunia, and sexual function score change were found.

RESUMEN

INTRODUCTION AND HYPOTHESIS: This was a planned secondary analysis of a systematic review that described sexual function outcomes following pelvic organ prolapse (POP) surgery. We aimed to describe the relationship of pre- and postoperative vaginal anatomic measures with sexual function outcomes. Data Sources included the Medline, Embase, and clinicaltrials.gov databases from inception to April 2018. METHODS: The original systematic review included prospective, comparative studies that reported sexual function outcomes before and following POP surgery. Studies were extracted for population characteristics, sexual function outcomes, and vaginal anatomy, including total vaginal length (TVL) and genital hiatus. By meta-regression, we analyzed associations across studies between vaginal anatomic measurements and sexual function using the Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire-12 (PISQ-12) and dyspareunia outcomes. RESULTS: We screened 3124 abstracts and identified 74 papers representing 67 original studies. Among these, 14 studies reported TVL and PISQ-12 outcomes. Nine studies reported TVL and dyspareunia outcomes, eight studies reported GH and PISQ-12 outcomes, and seven studies reported GH and dyspareunia outcomes. We found no associations between anatomic measures and PISQ-12 or dyspareunia, although, we found a statistically significant association found between preoperative TVL and change in PISQ-12. CONCLUSION: Across studies, the evidence does not support an association between vaginal anatomy and either validated, condition-specific sexual function questionnaires or dyspareunia. However, no study has directly analyzed these associations in the setting of pelvic floor reconstructive surgery.

RESUMEN

OBJECTIVE: To perform a systematic review of randomized controlled trials (RCTs) studying postoperative void trials (VTs) following gynecologic and urogynecologic surgery to investigate (1) the optimal postoperative VT methodology and (2) the optimal time after surgery to perform a VT. DATA SOURCES: PubMed, Embase, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov. METHOD OF STUDY SELECTION: We systematically searched the aforementioned data sources from inception to November 22, 2019, using a combination of subject headings and keywords for the following 3 concepts: gynecologic surgery (prolapse, benign gynecologic, and incontinence surgery), postoperative period, and voiding. We identified any RCT in English that studied VT methodology or timing in patients undergoing benign gynecologic or urogynecologic surgery. Discrepancies were adjudicated by a third reviewer. We followed the standard systematic review methodology and used the Jadad scoring system to assess bias. Extracted study outcomes included the following: proportion of patients discharged home with catheter, proportion of VT failure, surgery for retention, retention after initial VT, postoperative calls and visits, time in postanesthesia care unit (PACU), time to discharge, time to spontaneous void, duration of catheterization, patient and provider burden, and urinary tract infection (UTI). TABULATION, INTEGRATION, AND RESULTS: We double screened 618 abstracts and clinical trial descriptions, assessed 56 full-text articles, and ultimately included 21 RCTs. The evidence was of low to moderate quality overall. The studies were divided into the following 2 categories: VT methodology (10 studies) and VT timing (11 studies). VT methodology included backfill-assisted (in operating room vs PACU), autofill, and force of stream studies. One RCT compared backfill-assisted with and without postvoid residual volume check. Outcomes were similar for all VT methods, except backfill-assisted decreased time to spontaneous void compared with autofill. In the VT timing category, earlier VT performance correlated with a shorter time to discharge, time to spontaneous void, duration of catheterization, and lower patient burden and UTI rate but had a higher rate of retention after initial VT. There was no difference between earlier vs later VT timing for proportion of discharged home with catheter or rate of VT failure. No studies reported outcomes of provider burden or postoperative calls. CONCLUSION: In comparing VT methodologies, VT by backfill-assisted (in operating room vs PACU, ± postvoid residual volume), autofill, and force of stream resulted in similar outcomes with no one method being superior. Performing VT at an earlier postoperative time point results in shorter time to discharge and spontaneous void, shorter duration of catheterization, lower patient burden, and lower UTI risk, but it may increase the risk of retention after initial VT.

RESUMEN

Urinary incontinence (UI) is the involuntary loss of urine. UI is a prevalent condition that affects people of all ages, becoming more common with older age, and which negatively affects the lives of millions of people. Although the pathophysiology behind UI is still being researched, we review here the basic neuromuscular system regulating urinary control and several other potential factors influencing the lower urinary tract dysfunction that contributes to UI including the urobiome and genetic variants. The specific subtypes, risk factors and findings associated with UI are reviewed.

RESUMEN

OBJECTIVE: Our primary objective was to assess the current state of pain and opioid education in obstetrics and gynecology (OBGYN) by performing a detailed review of the national educational curricula guiding OBGYN residency and fellowship training programs in the United States. METHODS: From 2019 to 2020 we reviewed seven documents created to guide learning and structure educational training for OBGYN residency and fellowship programs in the United States: the Council on Resident Education in Obstetrics and Gynecology (CREOG) Educational Objectives Core Curriculum in Obstetrics and Gynecology, the 2016 Educational Objectives-Fellowship in Minimally Invasive Gynecologic Surgery, and the 2018 Guides to Learning in Complex Family Planning, Female Pelvic Medicine & Reconstructive Surgery, Gynecologic Oncology, Maternal Fetal Medicine, and Reproductive Endocrinology and Infertility. Each document was reviewed by two authors to assess for items referring to pain or opioids. RESULTS: The CREOG educational objectives, used to inform educational curricula for residency programs, were the most comprehensive, mentioning pain and/or opioid educational objectives the highest number of times and including the most categories. The CREOG document was followed by the Guides to Learning for Gynecologic Oncology and for Minimally Invasive Gynecologic Surgery. The Reproductive Endocrinology and Infertility Guide to Learning did not mention pain and/or opioids in the educational objectives.

RESUMEN

INTRODUCTION AND HYPOTHESIS: The COVID-19 pandemic and the desire to "flatten the curve" of transmission have significantly affected the way providers care for patients. Female Pelvic Medicine and Reconstructive Surgeons (FPMRS) must provide high quality of care through remote access such as telemedicine. No clear guidelines exist on the use of telemedicine in FPMRS. Using expedited literature review methodology, we provide guidance regarding management of common outpatient urogynecology scenarios during the pandemic. METHODS: We grouped FPMRS conditions into those in which virtual management differs from direct in-person visits and conditions in which treatment would emphasize behavioral and conservative counseling but not deviate from current management paradigms. We conducted expedited literature review on four topics (telemedicine in FPMRS, pessary management, urinary tract infections, urinary retention) and addressed four other topics (urinary incontinence, prolapse, fecal incontinence, defecatory dysfunction) based on existing systematic reviews and guidelines. We further compiled expert consensus regarding management of FPMRS patients in the virtual setting, scenarios when in-person visits are necessary, symptoms that should alert providers, and specific considerations for FPMRS patients with suspected or confirmed COVID-19. RESULTS: Behavioral, medical, and conservative management will be valuable as first-line virtual treatments. Certain situations will require different treatments in the virtual setting while others will require an in-person visit despite the risks of COVID-19 transmission. CONCLUSIONS: We have presented guidance for treating FPMRS conditions via telemedicine based on rapid literature review and expert consensus and presented it in a format that can be actively referenced.

RESUMEN

BACKGROUND: Data on the experience that women who undergo urogynecologic surgery have with postoperative catheterization are severely limited. As the importance of our patients' perioperative experience becomes more valued, assessment of the burden of postoperative catheterization, which has not yet been performed, is increasingly needed. OBJECTIVE: The aim of this study was to compare catheter burden in women who self-selected use of an indwelling Foley catheter vs clean intermittent self-catheterization for voiding dysfunction after reconstructive pelvic surgery. STUDY DESIGN: This is a nested study within a nonblinded randomized controlled trial of 2 different voiding trial protocols that was conducted from March to October 2017. Women who underwent pelvic organ prolapse and/or stress urinary incontinence surgery who were English speaking and ≥18 years old with a preoperative postvoid residual <100 mL were included. Participants who did not pass their voiding trial were discharged with an indwelling Foley catheter or self-catheterization per participant preference. Our primary outcome was catheter burden at 1 week after surgery assessed by the Short-Term Catheter Burden Questionnaire, which is a validated 6-item survey comprised of 2 subscales: difficulty of use and embarrassment. Scores range from 3-15 with higher scores indicating greater difficulty and/or embarrassment, and the sum of the 2 subscale scores measures total catheter burden with a higher score indicating greater burden. Secondary outcomes included the rate of urinary tract infection, the number of postoperative clinic visits, and the number of postoperative phone calls. RESULTS: Of 150 participants, 77 women (51%) did not pass their voiding trial; of those, 47 women (61%) were discharged home with an indwelling catheter and 30 women (39%) with self-catheterization. Baseline demographics were similar, except that women who chose an indwelling Foley catheter were older (62±11 vs 55±11 years; P<.01). There were no significant differences between indwelling Foley catheter and self-catheterization in total catheter burden score (18±5 vs 18±6; P=.77), difficulty of use subscale score (8±3 vs 9±3; P=.20), or embarrassment subscale score (10±4 vs 9±4; P=.12). For secondary outcomes, there were no significant differences in rate of urinary tract infection (23% indwelling vs 30% self-catheterization; P=.60). Consistent with study protocol, women who were discharged with an indwelling Foley catheter did have more postoperative clinic visits (2±1 vs 1±1 visits; P<.01), and those women who were discharged with self-catheterization had more postoperative phone calls (2±3 vs 5±3 phone calls; P<.01). Otherwise there was no significant difference in nonvoiding-related clinic visits (1±1 visits for indwelling and self-catheterization; P=.15) or postoperative phone calls (1±2 indwelling vs 2±3 self-catheterization calls; P=.31). CONCLUSION: In women who used either an indwelling Foley catheter or clean intermittent self-catheterization for management of postoperative voiding dysfunction after pelvic reconstructive surgery, there were no differences in difficulty of use, embarrassment, or overall catheter burden. There were also no differences in nonvoiding-related postoperative phone calls or clinic visits, with similar rates of urinary tract infection between the 2 groups.

RESUMEN

INTRODUCTION AND HYPOTHESIS: We aimed to systematically review the literature on pelvic organ prolapse (POP) surgery with uterine preservation (hysteropexy). We hypothesized that different hysteropexy surgeries would have similar POP outcomes but varying adverse event (AE) rates. METHODS: MEDLINE, Cochrane, and clinicaltrials.gov databases were reviewed from inception to January 2018 for comparative (any size) and single-arm studies (n ≥ 50) involving hysteropexy. Studies were extracted for participant characteristics, interventions, comparators, outcomes, and AEs and assessed for methodological quality. RESULTS: We identified 99 eligible studies: 53 comparing hysteropexy to POP surgery with hysterectomy, 42 single-arm studies on hysteropexy, and four studies comparing stage ≥2 hysteropexy types. Data on POP outcomes were heterogeneous and usually from <3 years of follow-up. Repeat surgery prevalence for POP after hysteropexy varied widely (0-29%) but was similar among hysteropexy types. When comparing sacrohysteropexy routes, the laparoscopic approach had lower recurrent prolapse symptoms [odds ratio (OR) 0.18, 95% confidence interval (CI) 0.07-0.46), urinary retention (OR 0.05, 95% CI 0.003-0.83), and blood loss (difference -104 ml, 95% CI -145 to -63 ml) than open sacrohysteropexy. Laparoscopic sacrohysteropexy had longer operative times than vaginal mesh hysteropexy (difference 119 min, 95% CI 102-136 min). Most commonly reported AEs included mesh exposure (0-39%), urinary retention (0-80%), and sexual dysfunction (0-48%). CONCLUSIONS: Hysteropexies have a wide range of POP recurrence and AEs; little data exist directly comparing different hysteropexy types. Therefore, for women choosing uterine preservation, surgeons should counsel them on outcomes and risks particular to the specific hysteropexy type planned.

RESUMEN

OBJECTIVE: We aimed to systematically review the literature on apical pelvic organ prolapse surgery with uterine preservation compared with prolapse surgeries including hysterectomy and provide evidence-based guidelines. DATA SOURCES: The sources for our data were MEDLINE, Cochrane, and clinicaltrials.gov databases from inception to January 2017. STUDY ELIGIBILITY CRITERIA: We accepted randomized and nonrandomized studies of uterine-preserving prolapse surgeries compared with those involving hysterectomy. STUDY APPRAISAL AND SYNTHESIS METHODS: Studies were extracted for participant information, intervention, comparator, efficacy outcomes, and adverse events, and they were individually and collectively assessed for methodological quality. If 3 or more studies compared the same surgeries and reported the same outcome, a meta-analysis was performed. RESULTS: We screened 4467 abstracts and identified 94 eligible studies, 53 comparing uterine preservation to hysterectomy in prolapse surgery. Evidence was of moderate quality overall. Compared with hysterectomy plus mesh sacrocolpopexy, uterine preservation with sacrohysteropexy reduces mesh exposure, operative time, blood loss, and surgical cost without differences in prolapse recurrence. Compared with vaginal hysterectomy with uterosacral suspension, uterine preservation in the form of laparoscopic sacrohysteropexy improves the C point and vaginal length on the pelvic organ prolapse quantification exam, estimated blood loss, postoperative pain and functioning, and hospital stay, but open abdominal sacrohysteropexy worsens bothersome urinary symptoms, operative time, and quality of life. Transvaginal mesh hysteropexy (vs with hysterectomy) decreases mesh exposure, reoperation for mesh exposure, postoperative bleeding, and estimated blood loss and improves posterior pelvic organ prolapse quantification measurement. Transvaginal uterosacral or sacrospinous hysteropexy or the Manchester procedure compared with vaginal hysterectomy with native tissue suspension both showed improved operative time and estimated blood loss and no worsening of prolapse outcomes with uterine preservation. However, there is a significant lack of data on prolapse outcomes >3 years after surgery, the role of uterine preservation in obliterative procedures, and longer-term risk of uterine pathology after uterine preservation. CONCLUSION: Uterine-preserving prolapse surgeries improve operating time, blood loss, and risk of mesh exposure compared with similar surgical routes with concomitant hysterectomy and do not significantly change short-term prolapse outcomes. Surgeons may offer uterine preservation as an option to appropriate women who desire this choice during apical prolapse repair.

RESUMEN

OBJECTIVES: To evaluate the relation between voided volume and void trial "success" to create an algorithm that minimizes the need for postvoid residual volume (PVR) assessment in backfill-assisted void trials. METHODS: This article is an ancillary analysis of deidentified data from a randomized trial evaluating prophylactic antibiotics after urogynecologic surgery. Void trials were routinely performed after surgery; voided volumes, PVR, and void trial outcomes were collected. The void trial regimen was as follows: the bladder was backfilled with 300 mL of normal saline or until the patient reported the urgency to void, the catheter was removed, and the participant was prompted to void immediately. PVR volume was measured either by sonographic bladder scan or catheterization. Voided volumes were categorized in 25-mL increments from 50 to 225 mL. For each voided volume range, the PVR and void trial outcome data were incorporated to calculate sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) in terms of ability of voided volume alone to predict a passing void trial result. An algorithm was created using the voided volumes that optimize PPV and NPV. RESULTS: The study population included 255 participants. Voided volumes <100 mL and ≥200 mL were identified as optimal thresholds to predict failure and passage of backfill-assisted void trials, respectively. When patients voided <100 mL, 3% passed their void trial (NPV odds ratio 96.7, 95% confidence interval 88.6-99.5). When patients voided ≥200 mL, 97% passed (PPV odds ratio 97.4, 95% confidence interval 93.5-99.3). CONCLUSIONS: We propose an algorithm for void trials after urogynecologic surgery. After backfilling the bladder if voided volume is ≥200 mL, the void trial is successful and no PVR is needed; if voided volume is between 100 and 199 mL, the void trial is indeterminate and PVR is recommended; and if voided volume is <100 mL, the void trial is unsuccessful and catheterization is needed. Applying this algorithm to our study population would have eliminated the need for PVR in 85% of patients. Calculated PPVs and NPVs depend on the prevalence of voiding dysfunction in the population being studied, and therefore may be unique to our institution.

RESUMEN

INTRODUCTION: Pelvic floor disorders affect vaginal anatomy and may affect sexual function. AIMS: The aims of this study were to explore the relationship between vaginal anatomy and sexual activity in women with symptomatic pelvic floor disorders and to assess whether vaginal measurements (topography) correlate with sexual function. METHODS: This is a retrospective cohort study comparing sexually active and nonsexually active women planning urogynecologic surgery. Our primary outcome was the difference in vaginal topography based on Pelvic Organ Prolapse Quantification (POP-Q) exam between cohorts. Correlations between POP-Q measurements and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire short form (PISQ-12) scores were assessed in sexually active women. MAIN OUTCOME MEASURE: The POP-Q is a quantitative and standardized examination for prolapse. The PISQ-12 is a condition-specific sexual function questionnaire validated in sexually active women with pelvic floor disorders. RESULTS: Of 535 women, 208 (39%) were sexually active and 327 (61%) were not. Median genital hiatus (GH) and perineal body (PB) measurements and a PB:GH ratio were not significantly different between the two cohorts. Total vaginal length (TVL) was longer in sexually active women (median 9 vs. 8 cm, P<0.001). In a linear regression analysis controlling for potential confounders, sexually active women still had a longer TVL by 0.4 cm (95% confidence interval 0.07, 0.6 cm) compared with those who were not sexually active. Of the 327 nonsexually active women, 28% indicated they avoided sexual activity because of pelvic floor symptoms. There was poor correlation between TVL, GH, PB, and PB : GH ratio with PISQ-12 scores (r=0.10, -0.05, -0.09, -0.03, respectively). CONCLUSIONS: In women with pelvic floor disorders, sexual activity is associated with a longer vaginal length. One-quarter of women indicated they avoided sexual activity because of pelvic floor symptoms. Vaginal topography does not correlate with sexual function based on PISQ-12 scores.

RESUMEN

AIMS: To design an optimal rat model for studying sacral neurostimulation (SNS), and examine the effect of SNS on myogenic non-voiding contractions (NVC) during filling before and after intraluminal irritation. METHODS: Bilateral paired bipolar SNS was performed in 10 female urethane anesthetized Sprague-Dawley rats at the L6-S1 trunks at 10 Hz, 0.1 msec pulse duration and 0.15-0.80 mA (below motor threshold). Transvesical cystometry was performed before and during SNS under conditions of control (saline, N = 10) and irritation [0.25% acetic acid (AA), N = 5]. RESULTS: Functional bladder capacity (FBC) and NVC count were significantly increased during SNS under both control and irritation conditions (P < 0.01 for all). In six instances (four in control, two in irritation), micturition reflexes were completely inhibited by SNS resulting in overflow incontinence. Filling compliance, NVC period and NVC maximum amplitude were not affected by SNS (P > 0.05 for all). Non-parametric two-way analysis of variance for repeated measures revealed increased FBC and NVC count during SNS under both control and irritation conditions (P = 0.004 for both, N = 5 rats). Linear regression analysis of NVC count versus FBC revealed a slope significantly different than zero, independent of control or irritation conditions (slope 33.10 ± 2.43, R(2) = 0.81, P < 0.001). CONCLUSIONS: This model achieved reliable, reversible and robust increases in bladder capacity up to overflow incontinence at stimulations below somatic motor threshold. SNS dramatically increased FBC and reversed AA-induced changes without affecting the character of normal NVC associated with bladder filling. Increased number of NVC is simply a consequence of increased fill time.
