The Response of the Urinary Microbiome to Botox.

INTRODUCTION AND HYPOTHESIS: Our objective was to evaluate if botox alters the urinary microbiome of patients with overactive bladder and whether this alteration is predictive of treatment response. METHODS: This multicenter prospective cohort study included 18-89-year-old patients undergoing treatment for overactive bladder with 100 units of botox. Urine samples were collected by straight catheterization on the day of the procedure (S1) and again 4 weeks later (S2). Participants completed the Patient Global Impression of Improvement form at their second visit for dichotomization into responders and nonresponders. The microbiome was sequenced using 16s rRNA sequencing. Wilcoxon signed rank and Wilcoxon rank sum were used to compare the microbiome, whereas chi-square, Wilcoxon rank sum, and the independent t-test were utilized for clinical data. RESULTS: Sixty-eight participants were included in the analysis. The mean relative abundance and prevalence of Beauveria bassiana, Xerocomus chrysenteron, Crinipellis zonata, and Micrococcus luteus were all found to increase between S1 and S2 in responders; whereas in nonresponders the mean relative abundance and prevalence of Pseudomonas fragi were found to decrease. The MRA and prevalence of Weissella cibaria, Acinetobacter johnsonii, and Acinetobacter schindleri were found to be greater in responders than nonresponders at the time of S1. Significant UM differences in the S1 of patients who did (n = 5) and did not go on to develop a post-treatment UTI were noted. CONCLUSIONS: Longitudinal urobiome differences may exist between patients who do and do not respond to botox.

Development of a machine learning-based predictive model for prediction of success or failure of medical management for benign prostatic hyperplasia.

OBJECTIVE: To develop a novel predictive model for identifying patients who will and will not respond to the medical management of benign prostatic hyperplasia (BPH). METHODS: Using data from the Medical Therapy of Prostatic Symptoms (MTOPS) study, several models were constructed using an initial data set of 2172 patients with BPH who were treated with doxazosin (Group 1), finasteride (Group 2), and combination therapy (Group 3). K-fold stratified cross-validation was performed on each group, Within each group, feature selection and dimensionality reduction using nonnegative matrix factorization (NMF) were performed based on the training data, before several machine learning algorithms were tested; the most accurate models, boosted support vector machines (SVMs), being selected for further refinement. The area under the receiver operating curve (AUC) was calculated and used to determine the optimal operating points. Patients were classified as treatment failures or responders, based on whether they fell below or above the AUC threshold for each group and for the whole data set. RESULTS: For the entire cohort, the AUC for the boosted SVM model was 0.698. For patients in Group 1, the AUC was 0.729, for Group 2, the AUC was 0.719, and for Group 3, the AUC was 0.698. CONCLUSION: Using MTOPS data, we were able to develop a prediction model with an acceptable rate of discrimination of medical management success for BPH.

The impact of urinary incontinence on multiple health outcomes: an umbrella review of meta-analysis of observational studies.

BACKGROUND AND AIM: We aimed to capture the breadth of health outcomes that have been associated with the presence of Urinary Incontinence (UI) and systematically assess the quality, strength, and credibility of these associations through an umbrella review and integrated meta-analyses. METHODS: We assessed meta-analyses of observational studies based on random-effect summary effect sizes and their p-values, 95% prediction intervals, heterogeneity, small-study effects, and excess significance. We graded the evidence from convincing (Class I) to weak (Class IV). RESULTS AND DISCUSSION: From 3172 articles returned in search of the literature, 9 systematic reviews were included with a total of 41 outcomes. Overall, 37 out of the 41 outcomes reported nominally significant summary results (p < 0.05), with 22 associations surviving the application of a more stringent p-value (p < 10-6). UI was associated with worse scores than controls in female sexual function (Class II), while it was also associated with a higher prevalence of depression (odds ratio [OR] = 1.815; 95% confidence interval [CI]: 1.551-2.124), and anxiety (OR = 1.498; 95% CI: 1.273-1.762) (Class IV). UI was associated with poorer quality of life (QoL), higher rate of mortality (hazard ratio = 2.392; 95% CI: 2.053-2.787) an increase in falls, frailty, pressure ulcers, diabetes, arthritis, and fecal incontinence (Class IV). CONCLUSIONS: UI is associated with female sexual dysfunction, with highly suggestive evidence. However, the evidence of other adverse outcomes including depression, anxiety, poorer QoL, higher mortality, falls, pressure ulcers, diabetes, arthritis, fecal incontinence, and frailty is only weak. A multidimensional approach should be taken in managing UI in the clinical setting.

Opioid use following pelvic reconstructive surgery: a predictive calculator.

INTRODUCTION AND HYPOTHESIS: Our objective was to evaluate the amount of opioids used by patients undergoing surgery for pelvic floor disorders and identify risk factors for opioid consumption greater than the median. METHODS: This was a prospective cohort study of 18- to 89-year-old women undergoing major urogynecological surgery between 1 November2020 and 15 October 2021. Subjects completed one preoperative questionnaire ("questionnaire 1") that surveyed factors expected to influence postoperative pain and opioid use. At approximately 1 and 2 weeks following surgery, patients completed two additional questionnaires ("questionnaire 2" and "questionnaire 3") about their pain scores and opioid use. Risk factors for opioid use greater than the median were assessed. Finally, a calculator was created to predict the amount of opioid used at 1 week following surgery. RESULTS: One hundred and ninety patients were included. The median amount of milligram morphine equivalents prescribed was 100 (IQR 100-120), whereas the median amount used by questionnaire 2 was 15 (IQR 0-50) and by questionnaire 3 was 20 (IQR 0-75). On multivariate logistic regression, longer operative time (aOR 1.64 per hour of operative time, 95% CI 1.07-2.58) was associated with using greater than the median opioid consumption at the time of questionnaire 2; whereas for questionnaire 3, a diagnosis of fibromyalgia (aOR=16.9, 95% CI 2.24-362.9) was associated. A preliminary calculator was created using the information collected through questionnaires and chart review. CONCLUSIONS: Patients undergoing surgery for pelvic floor disorders use far fewer opioids than they are prescribed.

A preliminary evaluation of in vivo response to a filament-wound macroporous collagen midurethral sling in an ovine model.

Stress urinary incontinence (SUI) impacts ~1/3 of women over age 50. Negative publicity around PP meshes used in pelvic prolapse repair drives the need for identifying alternative biomaterials for SUI repair. Our study evaluated in vivo response to collagen sling implanted in an ovine model. Electrocompacted collagen threads were filament wound as slings and crosslinked in genipin. Collagen slings were implanted suburethrally mimicking the transvaginal tape technique. Main study groups were: Collagen sling (n = 3, 6 months) and PP sling (n = 3, 6 months). Collagen sling was also tested at 3-weeks (n = 1) to observe early-stage tissue response and 1-year (n = 2) to assess biomaterial longevity in a preliminary capacity. Collagen slings healed to a fibrous ligament texture at 6 months and maintained such texture to 1 year. Histological scoring indicated biocompatible responses to collagen slings with no adverse events. All study groups exhibited complete tissue ingrowth and interstitial de novo collagen deposition at all time points. Collagen threads induced orderly de novo collagen deposition that was aligned along long axes of threads. Tissue infiltrated collagen slings that were explanted at 6 and 12 months presented similar structural strength with native tissues such as vagina and fascia, and PP (Lynx) slings (p > .05). With the limitation of low number of animals per time point in hindsight, this preliminary study justifies evaluation of collagen slings in a larger sample size of animals, particularly to assess persistence of ligamentous tissue response over longer durations than 1-year.

Skene's Gland Malignancy: A Case Report and Systematic Review.

OBJECTIVE: To present a recent clinical case of Skene's gland carcinoma and review all published literature of Skene's gland malignancy with associated treatment and outcomes. METHODS: We review a new case of metastatic Skene's gland adenocarcinoma. We then performed a systematic search of PubMed and Ovid-Medline through December 2021 and retrieved English language articles for review. Peer-reviewed articles were deemed eligible if they included patients with Skene's gland malignancy. Reports were reviewed for pathologic accuracy, patient characteristics, clinical presentation, tumor pathology, treatment and outcome. RESULTS: We reviewed 211 articles and included 15 cases from 1974 to 2022. The median patient age was 71 years (range 46-88). The most common presentation was an asymptomatic periurethral or urethral lesion in five cases (33.3%), followed by hematuria or vaginal bleeding in three patients (20.0%). In eight cases, a prostate-specific antigen was measured and found to be elevated, range 0.8-60.8 ng/mL. Treatment approaches varied and included local excision in eight cases, radical surgical resection in two cases, radiation therapy in two cases, and adjunctive androgen deprivation therapy in one case. Pathology was consistent with adenocarcinoma resembling prostate in all cases. In all cases tested, prostate-specific antigen normalized after definitive therapy of any type. Median follow up was 11.5 months, and there were no cases of recurrence or mortality secondary to Skene's gland adenocarcinoma. CONCLUSION: There are 15 published cases of a Skene's gland malignancy, all adenocarcinoma resembling prostate. Local excision is most often utilized for treatment, with androgen deprivation therapy emerging as a new treatment consideration.

Evaluation of the relationship of cholinergic metabolites in urine and urgency urinary incontinence.

INTRODUCTION AND HYPOTHESIS: To investigate differences in urine cholinergic metabolites in women with urinary urgency incontinence (UUI) and responders (R) and non-responders (NR) to anti-cholinergic medications (AC). METHODS: Patients with UUI and age-matched controls were evaluated pre- and post-treatment using OABSS, UDI-6 and IIQ-7. Controls were defined as having a cumulative OABSS of zero. Patients with UUI were treated with AC and followed for 12 weeks. Responders were those with a > 50% decrease in the total OABSS score. Urine samples were collected from all participants for evaluation. Metabolite detection was accomplished using commercial assay kits. Wilcoxon-rank sum test and Fisher's exact test were used to express differences between groups. Spearman's rho correlation coefficient was used to determine the relationship between acetylcholine (Ach), choline (Ch), acetylcholinesterase (AchE) and questionnaire scores. RESULTS: We recruited 39 with UUI and 33 controls. We found concentrations of Ch [29.0 (IQR: 24.2-42.5) µmol vs. 15.2 (IQR: 7.5-24.1) µmol] and Ach [65.8 (IQR: 30.4-101.8) nmol and 33.1 (IQR: 11.9-43.8) nmol] were higher in the UUI group compared to controls (p = 0.003 and p < 0.001, respectively] and no differences in AchE concentrations. In the UUI group, 43.6% responded to AC after 12 weeks of therapy. There were no differences in Ch or AchE levels between R and NR; Ach levels were higher in the R group [82.1 nmol (IQR: 54.8-118.1) vs. 50.3 nmol (IQR: 29.9-68.2), p = 0.007]. Ch and Ach were positively associated with pre-treatment OABSS parameters. CONCLUSIONS: Urine Ach is higher in responders to anti-cholinergic therapy, and urine cholinergic metabolites were higher in the UUI patients compared to controls.

Noncancerous Genitourinary Conditions as a Public Health Priority: Conceptualizing the Hidden Burden.

OBJECTIVE: To provide a conceptual framework to guide investigations into burdens of noncancerous genitourinary conditions (NCGUCs), which are extensive and poorly understood. METHODS: The National Institute of Diabetes and Digestive and Kidney Diseases convened a workshop of diverse, interdisciplinary researchers and health professionals to identify known and hidden burdens of NCGUCs that must be measured to estimate the comprehensive burden. Following the meeting, a subgroup of attendees (authors of this article) continued to meet to conceptualize burden. RESULTS: The Hidden Burden of Noncancerous Genitourinary Conditions Framework includes impacts across multiple levels of well-being and social ecology, including individual (ie, biologic factors, lived experience, behaviors), interpersonal (eg, romantic partners, family members), organizational/institutional (eg, schools, workplaces), community (eg, public restroom infrastructure), societal (eg, health care and insurance systems, national workforce/economic output), and ecosystem (eg, landfill waste) effects. The framework acknowledges that NCGUCs can be a manifestation of underlying biological dysfunction, while also leading to biological impacts (generation and exacerbation of health conditions, treatment side effects). CONCLUSION: NCGUCs confer a large, poorly understood burden to individuals and society. An evidence-base to describe the comprehensive burden is needed. Measurement of NCGUC burdens should incorporate multiple levels of well-being and social ecology, a life course perspective, and potential interactions between NCGUCs and genetics, sex, race, and gender. This approach would elucidate accumulated impacts and potential health inequities in experienced burdens. Uncovering the hidden burden of NCGUCs may draw attention and resources (eg, new research and improved treatments) to this important domain of health.

Pelvic Organ Prolapse Surgery in the Elderly and Frail: Safety of a Reconstructive Versus Obliterative Approach.

OBJECTIVES: The aim of this study was to compare the risk of complications associated with obliterative surgery versus reconstructive surgery in elderly and frail patients undergoing surgery for pelvic organ prolapse. METHODS: We performed a retrospective cohort study utilizing the American College of Surgeons National Surgical Quality Improvement Program Database from 2010 to 2017. We compared characteristics and perioperative complications in patients aged 80 years or older who underwent obliterative surgery versus reconstructive surgery. Multivariate logistic regression and propensity score matching were used to control for confounding. A subanalysis was performed that included patients who were considered frail as defined by the National Surgical Quality Improvement Program Modified Frailty Index 5. RESULTS: Of 1,654 total patients, reconstructive surgery was performed in 56.9% of patients, and obliterative surgery was performed in 43.1%. The respective composite complication rates were 9.2% and 9.8% (P = 0.69), whereas severe complications were experienced by 1.9% in the reconstructive group versus 0.8% in the obliterative group (P = 0.07). On multivariate logistic regression, reconstructive surgery was not significantly associated with the composite complication rate (adjusted odds ratio, 1.0; 95% confidence interval, 0.7-1.4; P = 0.80). After propensity score matching, composite complications did not differ between groups, but the rate of severe complications was significantly higher in patients who underwent reconstructive surgery compared with obliterative surgery (2.1% vs 0.8%; odds ratio, 2.53; 95% confidence interval, 1.01-6.36; P = 0.05). In frail patients only, complication rates did not differ between groups. CONCLUSIONS: In patients aged 80 years or older, the overall rate of complications did not differ between those who underwent reconstructive surgery versus obliterative surgery. However, propensity score matching identified an increased risk of the most severe complications in patients who underwent reconstructive surgery.

Tamsulosin vs placebo to prevent postoperative urinary retention following female pelvic reconstructive surgery: a multicenter randomized controlled trial.

BACKGROUND: Postoperative urinary retention is common after female pelvic reconstructive surgery. Alpha receptor antagonists can improve dysfunctional voiding by relaxing the bladder outlet and may be effective in reducing the risk of postoperative urinary retention. OBJECTIVE: This study aimed to determine whether tamsulosin is effective in preventing postoperative urinary retention in women undergoing surgery for pelvic organ prolapse. STUDY DESIGN: This was a multicenter, double-blind, randomized controlled trial between August 2018 and June 2020, including women undergoing surgery for pelvic organ prolapse. Patients were excluded from recruitment if they had elevated preoperative postvoid residual volume, history of postoperative urinary retention, or a contraindication to tamsulosin. Those who experienced cystotomy were excluded from analysis. Participants were randomized to a 10-day perioperative course of tamsulosin 0.4 mg vs placebo, beginning 3 days before surgery. A standardized voiding trial was performed on postoperative day 1. The primary outcome was the development of postoperative urinary retention, as defined by the failure of the voiding trial or subsequent need for catheterization to empty the bladder. Secondary outcomes included the rate of urinary tract infection and the impact on lower urinary tract symptoms as measured by the American Urological Association Symptom Index. RESULTS: Of 119 patients, 57 received tamsulosin and 62 received placebo. Groups were similar in regard to demographics, preoperative prolapse and voiding characteristics, and surgical details. Tamsulosin was associated with a lower rate of postoperative urinary retention than placebo (5 patients [8.8%] vs 16 patients [25.8%]; odds ratio, 0.28; 95% confidence interval, 0.09-81; P=.02). The number needed to treat to prevent 1 case of postoperative urinary retention was 5.9 patients. The rate of urinary tract infection did not differ between groups. American Urological Association Symptom Index scores significantly improved after surgery in both groups (median total score, 14 vs 7; P<.01). Scores related to urinary stream improved more in the tamsulosin group than in placebo (P=.03). CONCLUSION: In this placebo-controlled trial, tamsulosin use was associated with a reduced risk of postoperative urinary retention in women undergoing surgery for pelvic organ prolapse.

Baseline Brain Segmental Volumes in Responders and Nonresponders to Anticholinergic Therapy for Overactive Bladder Syndrome.

OBJECTIVE: Evaluate structural differences in brains of responders (R) and nonresponders (NR) to anticholinergic (AC) therapy for overactive bladder (OAB). MATERIALS AND METHODS: This was a retrospective cohort study of age matched women treated with an AC medication for OAB and underwent magnetic resonance imaging within 12 months before treatment. Data on pretreatment demographic and clinical variables and symptom severity was also collected.T1-weighted magnetic resonance images of the brain for each subject were segmented using FreeSurfer software. Structures included for analysis were cerebral cortex, white matter, subcortical gray matter, cerebellum, and brain stem.Nonresponders were defined as patients who reported less than 50% improvement after a minimum of 4 weeks on the maximum dose of the prescribed medication. Pairwise analysis between groups was performed using the Wilcoxon-Rank Sum test and Fisher exact test where appropriate. Spearman ρ was used to evaluate for correlations between neurologic structures and symptom severity. RESULTS: There were no differences in pretreatment characteristics or symptom severity between the 21 R and 18 NR. Nonresponders had lower volumes of the right caudal anterior cingulate gyrus white matter (1919 mm3 vs 2416 mm3, P = 0.008) and right parahippocampal gyrus white matter (1008 mm3 vs 1469 mm3, P = 0.001). Incontinence episode frequency showed a negative moderate correlation with the anterior cingulate gyrus white matter volume (ρ = -0.4228, P = 0.007). The right and left cerebellar cortices showed weak and moderate negative correlations to frequency of nocturia (ρ = -0.384, P = 0.02 and ρ -0.443, P = 0.005, respectively). CONCLUSION: There are measurable volumetric differences in brain structures in R and NR to AC therapy.

Evaluation of the ACS NSQIP surgical risk calculator in patients undergoing pelvic organ prolapse surgery.

INTRODUCTION AND HYPOTHESIS: The purpose of this study was to evaluate the accuracy of the American College of Surgeons National Surgery Quality Improvement Program (ACS NSQIP) surgical risk calculator in predicting postoperative complications in patients undergoing pelvic organ prolapse surgery. METHODS: We performed a retrospective review of 354 patients who underwent surgery for pelvic organ prolapse from 2013 to 2017 at a single academic institution. Patient medical information and surgical procedure were entered into the calculator to obtain predicted complication rates, which were compared with observed complications. Logistic regression, C-statistic, and Brier score were used to assess the accuracy of the calculator. RESULTS: Of 354 patients included in the analysis, 79.7% were under the age of 75, and 41.5% were classified as American Society of Anesthesiologists class ≥3. The majority of patients underwent robotic sacrocolpopexy (40.7%) or uterosacral ligament suspension (36.4%), followed by colpocleisis, abdominal sacrocolpopexy, and extraperitoneal suspension. Complications were experienced by 100 patients (28.3%). Most common complications were urinary tract infection (n = 57), surgical site infection (n = 42), and readmission (n = 16); other complications were rare. The surgical risk calculator displayed poor predictive ability for experiencing a complication (C-statistic = 0.547, Brier score = 0.25). CONCLUSIONS: The NSQIP surgical risk calculator displayed poor predictive ability in our cohort of patients undergoing surgery for pelvic organ prolapse, suggesting that this tool might have limited clinical applicability to individual patients in this population.

Perioperative Safety of Surgery for Pelvic Organ Prolapse in Elderly and Frail Patients.

OBJECTIVE: To evaluate the effects of old age and frailty on complication rates after surgery for pelvic organ prolapse. METHODS: The American College of Surgeons' National Surgical Quality Improvement Program database was used to identify patients who underwent surgery for prolapse from 2010 to 2017. We compared our control group (45-64 years, index population) to those aged 65-79 years (elderly) and 80 years and older (very elderly). Frailty was assessed using the National Surgical Quality Improvement Program Modified Frailty Index-5. The primary outcome was the composite rate of serious complications and mortality. RESULTS: We analyzed 27,403 patients in the index population, 20,567 in the elderly group, and 3,088 in the very elderly group. The composite rate of serious complications in the index population was 4.5%, compared with 4.7% in the elderly group (odds ratio [OR] 1.0, 95% CI 0.9-1.1) and 9.0% in the very elderly group (OR 2.1, 95% CI 1.8-2.4). Compared with the index group, the very elderly group had notably elevated risks of cardiac complications (OR 11.9, 95% CI 6.2-23.0), stroke (OR 26.6, 95% CI 5.4-131.8), and mortality (OR 39.9, 95% CI 8.6-184.7). On multivariate logistic regression, the only age group independently associated with serious complications was the very elderly group (adjusted odds ratio [aOR] 2.01, 95% CI 1.8-2.3). The Modified Frailty Index-5 score was independently predictive of complications (aOR 1.4, 95% CI 1.1-2.0). Stratified analysis using interaction terms revealed the Modified Frailty Index-5 score to be predictive of complications in the elderly age group (aOR 2.5, 95% CI 1.3-4.6), but not in the very elderly group. CONCLUSION: Serious complications surrounding prolapse surgery increase substantially in the cohort of patients older than 80 years of age, independent of frailty and medical or surgical risk factors.

Gene expression in stress urinary incontinence: a systematic review.

INTRODUCTION: A contribution of genetic factors to the development of stress urinary incontinence (SUI) is broadly acknowledged. This study aimed to: (1) provide insight into the genetic pathogenesis of SUI by gathering and synthesizing the available data from studies evaluating differential gene expression in SUI patients and (2) identify possible novel therapeutic targets and leads. METHODS: A systematic literature search was conducted through September 2017 for the concepts of genetics and SUI. Gene networking connections and gene-set functional analyses of the identified genes as differentially expressed in SUI were performed using GeneMANIA software. RESULTS: Of 3019 studies, 4 were included in the final analysis. A total of 13 genes were identified as being differentially expressed in SUI patients. Eleven genes were overexpressed: skin-derived antileukoproteinase (SKALP/elafin), collagen type XVII alpha 1 chain (COL17A1), plakophilin 1 (PKP1), keratin 16 (KRT16), decorin (DCN), biglycan (BGN), protein bicaudal D homolog 2 (BICD2), growth factor receptor-bound protein 2 (GRB2), signal transducer and activator of transcription 3 (STAT3), apolipoprotein E (APOE), and Golgi SNAP receptor complex member 1 (GOSR1), while two genes were underexpressed: fibromodulin (FMOD) and glucocerebrosidase (GBA). GeneMANIA revealed that these genes are involved in intermediate filament cytoskeleton and extracellular matrix organization. CONCLUSION: Many genes are involved in the pathogenesis of SUI. Furthermore, whole-genome studies are warranted to identify these genetic connections. This study lays the groundwork for future research and the development of novel therapies and SUI biomarkers in clinical practice.

Apical Suspension Utilization at the Time of Vaginal Hysterectomy for Pelvic Organ Prolapse Varies With Surgeon Specialty.

OBJECTIVE: To evaluate whether utilization of apical suspension procedures at the time of vaginal hysterectomy for pelvic organ prolapse varies with surgeon specialty. METHODS: This was a retrospective cohort study using data from the American College of Surgeons National Surgical Quality Improvement Program database from 2014 to 2016. International Classification of Diseases, Ninth Revision, Clinical Modification with a diagnosis of pelvic organ prolapse who underwent vaginal hysterectomy with any combination of pelvic reconstructive procedures. Propensity score matching using available preoperative clinical data was used to ameliorate selection bias by specialty at a ratio of 1 female pelvic reconstructive surgeon (FPMRS) surgeon to 2 obstetrician-gynecologists (OBG). Descriptive statistics were reported as means with standard deviations. Pairwise analysis using Student t test and Fisher exact test was performed where appropriate. RESULTS: After propensity score matching, there were 901 cases performed by FPMRS and 1802 performed by OBG. The overall utilization rate of apical suspension in the matched cohort was 81.7% for FPMRS and 19.8% for OBG (P < 0.001). Obstetrician-gynecologists were more likely to perform vaginal hysterectomy without apical suspension compared with FPMRS (44.3% vs 5.8%; P < 0.001) and were also more likely to perform nonapical vaginal repair without also performing an apical suspension, (17.7% vs 9.3%, P < 0.001), compared to urogynecologists. On multivariable logistic regression, having surgery performed by FPMRS was the only significant variable associated with an increased likelihood of undergoing apical suspension (adjusted odds ratio, 5.34; 95% confidence interval, 4.48-6.36). CONCLUSIONS: The FPMRS physicians are more likely to perform apical suspension with vaginal hysterectomy for prolapse repair compared with OBG.

Adnexectomy at the time of vaginal hysterectomy for pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: Preoperative counseling about salpingectomy with pelvic surgery is recommended by the American College of Obstetrics and Gynecology for ovarian cancer risk reduction. Our objective was to determine recent practice patterns and patient factors associated with salpingectomy with vaginal hysterectomy (VH) for pelvic organ prolapse (POP) in the USA. We hypothesize that salpingectomy might have become more common in recent years. METHODS: We queried the 2014-2016 National Surgical Quality Improvement Program database for women with a postoperative diagnosis of POP who underwent VH with any combination of pelvic reconstructive procedures. CPT codes do not differentiate salpingectomy from salpingo-oophorectomy, so subjects were stratified by whether concurrent adnexectomy was performed. Chi-squared and multivariate logistic regression analyses were used to evaluate characteristics associated with adnexectomy. Propensity score matching was utilized when evaluating postoperative complication rates. RESULTS: Of 5,344 women who underwent VH, 2019 (37.8%) had adnexectomy. Adnexectomy rate increased from 34.4% in 2014 to 46.8% in 2016 (p < 0.001). Adnexectomy rates of fellowship-trained urogynecologists and general gynecologists were similar (36.0% vs 38.8%, p = 0.197). On logistic regression analysis, patients more likely to undergo adnexectomy were < 65 years old (OR 0.844, CI 0.75-0.95, p = 0.004), had BMI <30 (OR 0.76, CI 0.68-0.86, p < 0.001), and were non-smokers (OR 0.78, CI 0.64-0.95, p = 0.016). Mean operative time was 17 min longer with adnexectomy (145 vs 128 min, p < 0.001). There were no differences in postoperative complications or reoperation rates between groups. CONCLUSIONS: Adnexectomy during VH for POP is safe and increasingly utilized by gynecology surgeons in the USA.

Stromal derived factor-1 plasmid as a novel injection for treatment of stress urinary incontinence in a rat model.

INTRODUCTION AND HYPOTHESIS: SDF-1 chemokine enhances tissue regeneration through stem cell chemotaxis, neovascularization and neuronal regeneration. We hypothesized that non-viral delivery of human plasmids that express SDF-1 (pSDF-1) may represent a novel regenerative therapy for stress urinary incontinence (SUI). METHODS: Seventy-six female rats underwent vaginal distention (VD). They were then divided into four groups according to treatment: pSDF-1 (n = 42), sham (n = 30), PBS (n = 1) and luciferase-tagged pSDF-1 (n = 3). Immediately after VD, the pSDF-1 group underwent immediate periurethral injection of pSDF-1, and the sham group received a vehicle injection followed by leak point pressure (LPP) measurement at the 4th, 7th and 14th days. Urogenital tissues were collected for histology. H&E and trichrome slides were analyzed for vascularity and collagen/muscle components of the sphincter. For the luciferase-tagged pSDF-1 group, bioluminescence scans (BLIs) were obtained on the 3rd, 7th and 14th days following injections. Statistical analysis was conducted using ANOVA with post hoc LSD tests. The Mann-Whitney U test was employed to make pair-wise comparisons between the treated and sham groups. We used IBM SPSS, version 22, for statistical analyses. RESULTS: BLI showed high expression of luciferase-tagged pSDF-1 in the pelvic area over time. VD resulted in a decline of LPP at the 4th day in both groups. The pSDF1-treated group demonstrated accelerated recovery that was significantly higher than that of the sham-treated group at the 7th day (22.64 cmH2O versus 13.99 cmH2O, p < 0.001). Functional improvement persisted until the 14th day (30.51 cmH2O versus 24.11 cmH2O, p = 0.067). Vascularity density in the pSDF-1-treated group was higher than in the sham group at the 7th and 14th days (p < 0.05). The muscle density/sphincter area increased significantly from the 4th to 14th day only in the pSDF-1 group. CONCLUSIONS: Periurethral injection of pSDF-1 after simulated childbirth accelerated the recovery of continence and regeneration of the urethral sphincter in a rat SUI model. This intervention can potentially be translated to the treatment of post-partum urinary incontinence.

Evaluation of Urine Choline Levels in Women With and Without Overactive Bladder Syndrome.

OBJECTIVE: The objective of this study was to determine whether levels of choline (Ch) differ in women with and without overactive bladder (OAB) symptoms. METHODS: New patients were evaluated using the overactive bladder symptom score; Medical, Epidemiologic, and Social Aspects of Aging (MESA) urgency incontinence questionnaire; and Impact Questionnaire 7 and provided a urine sample. Patients were stratified into asymptomatic controls, scoring 0 on overactive bladder symptom score and the MESA questionnaire, and patients with OAB and urgency incontinence (OAB-wet). Patients with conditions predisposing to OAB or had a history of OAB treatment were excluded. Choline detection was accomplished using a commercially available kit. Wilcoxon rank sum test and Fisher exact test were used to express differences between groups. Spearman ρ correlation was used to determine the relationship between Ch and questionnaire scores. Logistic regression was used to identify significant variables associated with OAB. RESULTS: Sixty-three women were included in the final analysis. Patients with OAB-wet were older (P = 0.001), more likely to be obese (P = 0.04), had greater apical descent (P = 0.02), were more likely to be postmenopausal (P = 0.01), and were more likely to have stress incontinence (P = 0.005). Choline was 34.8% lower in OAB compared with the controls (P = 0.014). Lower Ch levels were associated with higher MESA (Spearman ρ = -0.311, P = 0.03). After logistic regression, lower Ch (adjusted odds ratio [aOR], 0.97; 95% confidence interval [CI], 0.96-0.98), age (aOR, 1.12; 95% CI, 1.08-1.18), and body mass index (aOR, 1.09; 95% CI, 1.01-1.18) were significantly associated with OAB-wet. CONCLUSIONS: Choline levels are significantly decreased in women complaining of OAB with urgency incontinence, and lower levels are associated with higher MESA scores.

Evaluation of Choline and Acetylcholine Levels in Responders and Nonresponders to Anticholinergic Therapy for Overactive Bladder Syndrome.

OBJECTIVE: This study aimed to determine whether levels of choline (Ch) and acetylcholine (Ach) differ between responders and nonresponders to anticholinergic therapy. METHODS: Patients prescribed an anticholinergic were evaluated using the Overactive Bladder Symptom Score; Medical, Epidemiologic and Social Aspects of Aging and Incontinence Questionnaire; and Incontinence Impact Questionnaire-7. A 1-day voiding diary and a urine sample were collected. After treatment for 12 weeks, the questionnaires were administered and 1-day voiding diary was completed. Levels of Ach and Ch were measured by liquid chromatography with tandem mass spectrometry. Subjects were divided into responders and nonresponders. Wilcoxon rank sum test and Fisher exact test were used to express differences between groups. Spearman ρ correlation coefficient was used to determine the relationship between Ach and Ch and symptom severity, patient demographics, and questionnaire scores. RESULTS: Thirty-one women were included in the analysis. The treatment response rate was 48.8%. The median age was 67 years (interquartile range, 50-76 years), and median body mass index was 32.3 kg/m2 (27.5-40.6 kg/m2), with 41.2% having an additional complaint of stress incontinence. There were no significant differences in symptom severity or questionnaire scores between groups.The median Ch and Ach levels were higher in responders (28.6 vs 9.2 µL, P = 0.04) and (83.1 vs 18.7 nL, P = 0.02), respectively. Levels of both Ch and Ach had moderate positive correlations with the Medical, Epidemiologic and Social Aspects of Aging and Incontinence Questionnaire urgency urinary incontinence score (ρ = 0.533 [P = 0.002] and ρ = 0.453 [P = 0.01], respectively). CONCLUSION: In women with overactive bladder, urinary Ach and Ch levels are higher in responders to anticholinergic therapy compared with nonresponders.

Multimodal opioid-sparing postoperative pain regimen compared with the standard postoperative pain regimen in vaginal pelvic reconstructive surgery: a multicenter randomized controlled trial.

BACKGROUND: Postoperative pain control after urogynecological surgery has traditionally been opioid centered with frequent narcotic administration. Few studies have addressed optimal pain control strategies for vaginal pelvic reconstructive surgery that limit opioid use. OBJECTIVE: The objective of the study was to determine whether, ice packs, Tylenol, and Toradol, a novel opioid-sparing multimodal postoperative pain regimen has improved pain control compared with the standard postoperative pain regimen in patients undergoing inpatient vaginal pelvic reconstructive surgery. STUDY DESIGN: This was a multicenter randomized controlled trial of women undergoing vaginal pelvic reconstructive surgery. Patients were randomized to the ice packs, Tylenol, and Toradol postoperative pain regimen or the standard regimen. The ice packs, Tylenol, and Toradol regimen consists of around-the-clock ice packs, around-the-clock oral acetaminophen, around-the-clock intravenous ketorolac, and intravenous hydromorphone for breakthrough pain. The standard regimen consists of as-needed ibuprofen, as-needed acetaminophen/oxycodone, and intravenous hydromorphone for breakthrough pain. The primary outcome was postoperative day 1 pain evaluated the morning after surgery using a visual analog scale. Secondary outcomes included the validated Quality of Recovery Questionnaire, satisfaction scores, inpatient narcotic consumption, outpatient pain medication consumption, and visual analog scale scores at other time intervals. In all, 27 patients in each arm were required to detect a mean difference of 25 mm on a 100 mm visual analog scale (90% power). RESULTS: Thirty patients were randomized to ice packs, Tylenol, and Toradol and 33 to the standard therapy. Patient and surgical demographics were similar. The median morning visual analog scale pain score was lower in the ice packs, Tylenol, and Toradol group (20 mm vs 40 mm, P = .03). Numerical median pain scores were lower at the 96 hour phone call in the ice packs, Tylenol, and Toradol group (2 vs 3, P = .04). Patients randomized to the ICE-T regimen received fewer narcotics (expressed in oral morphine equivalents) from the postanesthesia care unit exit to discharge (2.9 vs 20.4, P < .001) and received fewer narcotics during the entire hospitalization (55.7 vs 91.2, P < .001). At 96 hour follow up, patients in the ice packs, Tylenol, and Toradol group used 4.9 ketorolac tablets compared with 4.6 oxycodone/acetaminophen tablets in the standard group (P = .81); however, ice packs, Tylenol, and Toradol patients required more acetaminophen than ibuprofen by patients in the standard arm (10.7 vs 6.2 tablets, P = .012). There were no differences in Quality of Recovery Questionnaire or satisfaction scores either in the morning after surgery or at 96 hour follow up. CONCLUSION: The ice packs, Tylenol, and Toradol multimodal pain regimen offers improved pain control the morning after surgery and 96 hours postoperatively compared with the standard regimen with no differences in patient satisfaction and quality of recovery. Ice packs, Tylenol, and Toradol can significantly limit postoperative inpatient narcotic use and eliminate outpatient narcotic use in patients undergoing vaginal pelvic reconstructive surgery.
