Prediction of Postoperative Urinary Tract Infection Following Benign Gynecologic Surgery

INTRODUCTION AND HYPOTHESIS

The objective was to develop a prediction model for urinary tract infection (UTI) after pelvic surgery.

METHODS

We utilized data from three tertiary care centers of women undergoing pelvic surgery. The primary outcome was a UTI within 8 weeks of surgery. Additional variables collected included procedural data, severity of prolapse, use of mesh, anti-incontinence surgery, EBL, diabetes, steroid use, estrogen use, postoperative catheter use, PVR, history of recurrent UTI, operative time, comorbidities, and postoperative morbidity including venous thromboembolism, surgical site infection. Two datasets were used for internal validation, whereas a third dataset was used for external validation. Algorithms that tested included the following: multivariable logistic regression, decision trees (DTs), naive Bayes (NB), random forest (RF), gradient boosting (GB), and multilayer perceptron (MP).

RESULTS

For the training dataset, containing both University of British Columbia and Mayo Clinic Rochester data, there were 1,657 patients, with 172 (10.4%) UTIs; whereas for the University of Calgary external validation data, there were a total of 392 patients with a UTI rate of 16.1% (n = 63). All models performed well; however, the GB, DT, and RF models all had an area under the curve (AUC) > 0.97. With external validation the model retained high discriminatory ability, DT: AUC = 0.88, RF: AUC = 0.88, and GB: AUC = 0.90.

CONCLUSIONS

A model with high discriminatory ability can predict UTI within 8 weeks of pelvic surgery. Future studies should focus on prospective validation and application of randomized trial models to test the utility of this model in the prevention of postoperative UTI.

Surgeon Counseling Regarding Return to Sexual Activity After Pelvic Reconstructive Surgery

IMPORTANCE

Patients highly value surgeon counseling regarding the first sexual encounters after pelvic reconstructive surgery.

OBJECTIVES

We performed a qualitative analysis of usual surgeon counseling regarding return to sexual activity after surgery for pelvic organ prolapse and/or urinary incontinence.

METHODS

Participating surgeons provided a written description of their usual patient counseling regarding return to sexual activity after pelvic organ prolapse or urinary incontinence surgery. Counseling narratives were coded for major themes by 2 independent reviewers; disagreements were arbitrated by the research team. Analysis was performed utilizing Dedoose software and continued until thematic saturation was reached.

RESULTS

Twenty-two surgeons participated, and thematic saturation was reached. Six major themes were identified: "Safety of Intercourse," "Specific Suggestions," "Surgical Sequelae," "Patient Control," "Partner Related," "Changes in Experience," and "No Communication." Nearly all participating surgeons included counseling on the safety of intercourse and reassurance that intercourse would not harm the surgical repair. Specific suggestions included different positions, use of lubrication, vaginal estrogen use, specific products/vendors, alternatives to (vaginal) intercourse, and the importance of foreplay. Surgical sequelae discussion included possible interventions for complications, such as persistent sutures in the vagina, abnormal bleeding, or de novo dyspareunia. Counseling regarding changes to the patient's sexual experience ranged from suggestion of improvement to an anticipated negative experience. Surgeons more commonly advised patients that their sexual experience would be worsened or different from baseline; discussion of improvement was less frequent.

CONCLUSIONS

Surgeon counseling regarding the postoperative return to sexual activity varies among pelvic reconstructive surgeons. Most reassure patients that intercourse is safe after surgery.

Anticipated Impact of Dobbs v Jackson Women's Health Organization on Training of Residents in Obstetrics and Gynecology: A Qualitative Analysis

Background

On June 24, 2022, the Supreme Court of the United States in the case of Dobbs v Jackson Women's Health Organization ended constitutional protection for abortion, thus severely restricting access to reproductive health care for millions of individuals. Concerns have arisen about the potential impact on medical students, residents, and fellows training in restricted areas and the effect on gynecologic training and the future provision of competent comprehensive women's health care in the United States.

Objective

To qualitatively explore the anticipated impacts of the Dobbs ruling on training in obstetrics and gynecology (OB/GYN).

Methods

A participatory action research approach employing methods of qualitative analysis was used. Trainees and leaders in national OB/GYN professional and academic organizations with missions related to clinical care and training of medical students, residents, and fellows in OB/GYN participated. Two focus groups were held via Zoom in July 2022. Using an iterative process, transcripts underwent coding by 2 independent researchers to identify categories and common themes. Themes were organized into categories and subcategories. An additional reviewer resolved discrepancies.

Results

Twenty-six OB/GYN leaders/stakeholders representing 14 OB/GYN societies along with 4 trainees participated. Eight thematic categories were identified: competency, provision of reproductive health care, residency selection, inequity in training, alternative training, law-based vs evidence-based medicine, morality and ethics, and uncertainty about next steps.

Conclusions

This qualitative study of leaders and learners in OB/GYN identified 8 themes of potential impacts of the Dobbs ruling on current and future training in OB/GYN.

Does size matter? Opioid use after laparoscopy for apical pelvic organ prolapse using an 8mm versus 10-12mm accessory port

STUDY OBJECTIVE

To determine if a change in lateral accessory port (LAP) size from 10-12mm to 8mm among women undergoing laparoscopic native tissue pelvic organ prolapse (POP) surgery was effective at reducing opioid use after surgery.

DESIGN

Prospective cohort of women taking part in a POP surgical registry.

SETTING

Tertiary academic hospital in Calgary, Canada.

PATIENTS

Women undergoing laparoscopic uterosacral ligament apical suspensions for stage ≥2 POP with either uterine preservation or concomitant hysterectomy. 92 women were included during a 15-month study period from June 2020 to September 2021.

INTERVENTIONS

Laparoscopic apical suspension using either a 10-12mm or 8mm LAP, with the change occurring at the mid-point of the study period. Fascial defects from 10-12mm ports were closed with a fascial closure device. Perioperative care and technique were otherwise unchanged.

MEASUREMENTS AND MAIN RESULTS

Post-operative opioid use was measured by mean morphine equivalent daily dose (MEDD), accounting for all oral and intravenous opioids used in the first 24-hours post-surgery. 50 cases (54.3%) used a 10-12mm LAP, 42 cases (45.7%) used an 8mm LAP. Mean MEDD after surgery with a 10-12mm LAP was significantly higher than with an 8mm LAP (35.3 (95% CI 24.9-45.6) vs. 13.6 (95% CI 8.0-19.2), p<0.001). Proportion of women who did not require opioids post-operatively was higher in the 8mm group (45.2%, n=19) than the 10-12mm group (18.0%, n=9) (cOR 3.76, 95% CI 1.47-9.66). Similarly, the proportion of women who did not fill an opioid prescription after discharge was higher in the 8mm group (35.7%, n=15) than the 10-12mm group (16.0%, n=8) (cOR 2.92, 95% CI 1.09-7.81). These results remained statistically significant after adjustment for age, body mass index, race/ethnicity, length of procedure, and concomitant procedures performed.

CONCLUSION

Compared to 10-12mm port, use of an 8mm LAP during laparoscopic native-tissue apical POP surgery is associated with decreased opioid use in the first 24 hours after surgery.

Sexual function after pelvic organ prolapse surgery: a systematic review comparing different approaches to pelvic floor repair

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.

Cannabinoids and bladder symptoms in multiple sclerosis

BACKGROUND

Research on the health benefits of cannabis has been limited because use remains restricted or illegal in most countries. Medical cannabis has been legal in Canada since 2001 and recreational use became legal in October 2018. While there are data that support a biological mechanism by which cannabinoids can impact various other symptoms of MS, the evidence of effectiveness of cannabis as a treatment for bladder symptoms remains unsettled. We conducted an exploratory study to describe the current trends of cannabis product consumption among people with MS (PwMS) and their association with perceived benefits on MS symptoms.

METHODS

A cross-sectional survey study of PwMS, recruited from the MS Clinic in Calgary, Alberta, Canada was undertaken. Logistic regression analyses were performed to assess the associations between cannabis consumption and improvement in bladder function symptoms.

RESULTS

There were 775 respondents out of 2899 PwMS contacted by email. Among respondents, 734 reported cannabis use in the past 3 months. There were 275 (37.5%) respondents who reported cannabis use in the prior 3 months, and 73.8% of these reported at least weekly use of cannabis. Among all users, 78.1% reported a primary medical or therapeutic indication for consumption. The most common modes of cannabis consumption were oral-edible (69.0%) and smoked (57.1%), while 59.3% used more than one mode of consumption and 2.6% used five different modes. The most common reasons for cannabis use were for sleep (58.3%), pain (51.5%), relaxation (44.4%), muscle spasms (40.2%), anxiety (33.8%) and depression (22.9%). Among the 19 participants who reported bladder symptoms as a main reason for cannabis use, 89.5% reported "better" bladder symptoms when using cannabis. Cannabis consumption in the past 3 months was associated with a two-fold increased odds of reporting improvement in urinary frequency, urinary urgency, bladder leakage and wetness, pad use and bladder emptying.

CONCLUSIONS

Cannabis is commonly used in this survey study of personal cannabis use among PwMS. Patterns of use, dosing, frequency and mode of delivery are diverse among survey respondents. This pilot study provides some initial glimpses into real world therapeutic use of cannabinoids among PwMS for bladder symptoms.

Relationship of postoperative vaginal anatomy and sexual function: a systematic review with meta-analysis

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.

Two Intraoperative Techniques for Midurethral Sling Tensioning: A Randomized Controlled Trial

OBJECTIVE

To evaluate whether the use of a Mayo Scissor as a suburethral spacer compared with a Babcock clamp holding a loop of tape under the urethra results in different rates of abnormal bladder outcomes 12 months after retropubic midurethral sling surgery.

METHODS

The MUST (Mid-Urethral Sling Tensioning) trial was a block-randomized, double-blind, multicenter clinical trial that allocated women to have their retropubic midurethral slings tensioned by Scissor or Babcock technique. The primary outcome (abnormal bladder) was a composite of persistent stress urinary incontinence (SUI), overactive bladder, and urinary retention. Secondary outcomes included outcomes of the composite, postoperative catheterization, incontinence-related questionnaires, repeat incontinence treatment, and uroflowmetry. Sample size of 159 in each arm (N=318) was planned for a superiority trial, hypothesizing a 10% difference in primary outcome.

RESULTS

From September 2015 to December 2017, 506 women were screened and 318 were randomized. Baseline characteristics were similar in each arm. At 12 months, 253 (79.6%) women provided information on primary outcome: 40 of 128 (31.3%) patients with midurethral slings tensioned by Scissor experienced abnormal bladder, compared with 23 of 125 (18.4%) of those with midurethral slings tensioned by Babcock (P=.018, relative difference 12.9%). Secondary analyses favored Babcock for median duration of catheterization and the proportions of women experiencing urinary retention requiring sling lysis. Uroflowmetry parameters suggest the Scissor technique is more restrictive. Rates of mesh erosion were lower for the Scissor arm. No differences occurred in proportions of women experiencing patient reported persistent SUI after surgery.

CONCLUSION

Abnormal bladder outcomes were 12.9% less frequent for women with midurethral slings tensioned by Babcock. Both techniques provided a comparable patient reported cure for SUI at 12 months. Women with midurethral slings tensioned by Scissors experienced more intervention for obstruction, whereas those with midurethral slings tensioned by Babcock experienced higher rates of mesh erosion. This information about how the postoperative courses differ allows surgeons to better counsel patients preoperatively or tailor their choice of technique.

A guide for urogynecologic patient care utilizing telemedicine during the COVID-19 pandemic: review of existing evidence

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.

Uterosacral vault suspension (USLS) at the time of hysterectomy: laparoscopic versus vaginal approach

INTRODUCTION AND HYPOTHESIS

To compare laparoscopic and vaginal approaches to uterosacral ligament vault suspension (USLS) by perioperative data, short-term complications, rates of successful concomitant adnexal surgery and procedural efficacy.

METHODS

Retrospective cohort of USLS procedures performed at the time of hysterectomy at a tertiary care center over a 3-year period. Patient demographics, surgical data, concomitant adnexal procedures and complications were abstracted from a surgical database and compared using parametric or non-parametric tests as appropriate. Validated questionnaires (POPDI-6, UDI-6, PROMIS) were used to collect information on recurrence and long-term complications. Patients were analyzed according to both intention-to-treat analysis based on the intended approach and the completed route of surgery to deal with intraoperative conversions.

RESULTS

Two hundred six patients met the criteria for inclusion; 152 underwent vaginal USLS (V-USLS) and 54 laparoscopic USLS (L-USLS). No statistically significant differences in mean case time, postoperative length of stay or perioperative infection were found. While no ureteric obstructions occurred in the L-USLS group, in the V-USLS group 14 (9%) obstructions occurred (p = 0.023). Postoperative urinary retention was higher with V-USLS (31% vs. 15%, p = 0.024). Rates of successfully completed adnexal surgery differed (56% vs. 98%, p < 0.001) in favor of L-USLS. Patient-reported symptomatic recurrence of prolapse was higher in the V-USLS group (41% vs. 24%, p = 0.046); despite this, re-treatment did not differ between the groups (0% vs. 7%, p = 0.113).

CONCLUSIONS

Perioperative case time and complications did not differ between approaches. However, rates of completed adnexal surgery were significantly higher in the laparoscopic group, which could influence surgical decisions concerning approaches to prolapse surgery.

Randomized controlled trial of silver-alloy-impregnated suprapubic catheters versus standard suprapubic catheters in assessing urinary tract infection rates in urogynecology patients

INTRODUCTION AND HYPOTHESIS

Catheter-associated urinary tract infections (UTI) are the most common health-care-related infections. We aimed to compare the UTI rate among women undergoing urogynecological procedures with a silver-alloy suprapubic catheter (SPC) and a standard SPC, and identify the risk factors predisposing patients to UTI.

METHODS

Patients who were to undergo placement of an SPC as part of pelvic organ prolapse surgery were enrolled between 1 August 2011 and 30 August 2017, and randomized to either standard SPC or silver-alloy SPC. Follow-up was performed at a postoperative visit or via a phone call at 6 weeks. The primary outcome was UTI.

RESULTS

Of the 288 patients who were randomized, 127 with standard SPC and 137 with silver-alloy SPC were included in the analysis. Twenty-nine out of 123 women with standard SPC (23.6%) and 24 out of 131 (18.3%) with silver-alloy SPC were diagnosed with UTI within 6 weeks postoperatively (p = 0.30). In univariate analysis, non-white race (odds ratio [OR] 5.36, 95% CI 1.16-24.73) and diabetes (OR 2.80, 95% CI 1.26-6.23) were associated with increased risk of UTI. On multivariate analysis, only diabetes remained an independent risk factor. Comparisons between groups were evaluated using two-sample t test for age, Chi-squared tests for diabetes, and Wilcoxon rank sum test for all other variables.

CONCLUSION

There was only a 5% difference in 6-week UTI rates between those who received standard vs silver-alloy SPC; the study was not powered to detect such a small difference. Diabetes was identified as a risk factor for SPC-associated UTI in women undergoing pelvic reconstructive surgeries.

Uterine preservation vs hysterectomy in pelvic organ prolapse surgery: a systematic review with meta-analysis and clinical practice guidelines

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.

A prospective study investigating the diagnostic agreement between urodynamics and dynamic cystoscopy in women presenting with mixed urinary incontinence

INTRODUCTION AND HYPOTHESIS

Patient history is often insufficient to identify type of urinary incontinence (UI). Multichannel urodynamic testing (UDS) is often used to clarify the diagnosis. Dynamic cystoscopy (DC) is a novel approach for testing bladder function. The primary objective of this study was to investigate the diagnostic agreement of UDS and DC in evaluating women with mixed urinary incontinence (MUI).

METHODS

Women presenting with MUI were approached for enrollment if UDS and DC were planned for further investigation. Investigators were blinded to history and comparative test results. McNemar's test and kappa coefficient were calculated to assess agreement between UDS and DC. Receiver operating characteristic (ROC) analysis was used to explore the best possible filling sensation cutoffs for DC that would best predict the filling sensation cutoffs from UDS.

RESULTS

Sixty participants were included, of whom, four were excluded for protocol violation. For the primary outcome measure of agreement, UDS and DC were concordant in 44/56 of stress urinary incontinence (SUI) cases (79%) with a κ= 0.54 and in 43/56 of urinary urge incontinence (UUI) cases (77%) with a κ= 0.54, indicating moderate, nearly substantial agreement. ROC analysis identified the best prediction of DC first urge to void as 148 cm³, strong urge 215 cm³, and maximum capacity at 246 cm³. These parameters were used to compare UDS UUI to DC UUI and resulted in a κ = 0.61 (p = 0.37), indicating substantial agreement.

CONCLUSIONS

When compared with UDS, DC shows moderate agreement for detection of SUI and substantial agreement for detection of UUI.

Validation of the Simulated Vaginal Hysterectomy Trainer

STUDY OBJECTIVE

To establish construct validity of the simulated vaginal hysterectomy trainer (SimVaHT).

DESIGN

A cross-sectional validation study (Canadian Task Force classification II-2).

SETTING

A single academic medical center in the United States.

SUBJECTS

Fourteen residents in obstetrics and gynecology (4 postgraduate year [PGY] 1, 4 PGY-2, 3 PGY-3 and 3 PGY-4). PGY-1 and PGY-2 residents were grouped to form the "junior level" cohort, whereas PGY-3 and PGY-4 residents comprised the "senior level" cohort.

INTERVENTIONS

Each participant underwent surgical skill simulation by performing a simulated vaginal hysterectomy on a practical, inexpensive vaginal hysterectomy trainer.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was resident surgical skill as assessed by the Objective Structured Assessment of Technical Skills Global Rating Scale (GRS). All obstetrics and gynecology residents were videotaped performing a simulated vaginal hysterectomy on the SimVaHT. The tapes were reviewed independently by 2 blinded urogynecology experts, each of whom provided a GRS score. The primary outcome was overall GRS scores. The secondary outcome was time to complete the exercise. GRS scores were compared between junior- and senior-level residents. Senior-level residents scored significantly higher on the GRS overall compared with junior-level residents (p = .008).

CONCLUSION

Construct validity was demonstrated for the SimVaHT. The SimVaHT is a practical and inexpensive tool that may improve resident vaginal surgical skills before their first case in the operating room.

Surgical Simulation and Competency

Simulation in surgical training is playing an increasingly important role as postgraduate medical education programs navigate an environment of increasing costs of education, increased attention on patient safety, and new duty hour restrictions. In obstetrics and gynecology, simulation has been used to teach many procedures; however, it lacks a standardized curriculum. Several different simulators exist for teaching various routes and aspects of hysterectomy. This article describes how a formal framework of increasing levels of competencies can be applied to simulation in teaching the procedure of hysterectomy.

A randomized clinical trial of how to best position retropubic slings for stress urinary incontinence: Development of a study protocol for the mid-urethral sling tensioning (MUST) trial

The goal of this trial is to compare two techniques for tensioning retropubic midurethral slings: a Mayo scissor between the tape and urethra vs. a Babcock clamp creating a measured loop underneath the urethra. The primary outcome is a composite of abnormal bladder function at 12 months post surgery. Abnormal bladder function is defined as bothersome stress incontinence or worsening over active bladder symptoms, a positive cough stress test, re-treatment of stress urinary incontinence, post-operative urinary retention requiring either catheterization beyond 6 weeks or surgical intervention. Secondary outcomes include the duration of post operative urinary retention, quality of life scores, and physical examination. This article describes the rationale and design of this clinical trial, which will be of interest to those who care for patient with pelvic floor disorders such as stress urinary incontinence.

Nonantimuscarinic treatment for overactive bladder: a systematic review

The purpose of the study was to determine the efficacy and safety of nonantimuscarinic treatments for overactive bladder. Medline, Cochrane, and other databases (inception to April 2, 2014) were used. We included any study design in which there were 2 arms and an n > 100, if at least 1 of the arms was a nonantimuscarinic therapy or any comparative trial, regardless of number, if at least 2 arms were nonantimuscarinic therapies for overactive bladder. Eleven reviewers double-screened citations and extracted eligible studies for study: population, intervention, outcome, effects on outcome categories, and quality. The body of evidence for categories of interventions were summarized and assessed for strength. Ninety-nine comparative studies met inclusion criteria. Interventions effective to improve subjective overactive bladder symptoms include exercise with heat and steam generating sheets (1 study), diaphragmatic (1 study), deep abdominal (1 study), and pelvic floor muscle training exercises (2 studies). Pelvic floor exercises are more effective in subjective and objective outcomes with biofeedback or verbal feedback. Weight loss with diet and exercise, caffeine reduction, 25-50% reduction in fluid intake, and pelvic floor muscle exercises with verbal instruction and or biofeedback were all efficacious. Botulinum toxin A improves urge incontinence episodes, urgency, frequency, quality of life, nocturia, and urodynamic testing parameters. Acupuncture improves quality of life and urodynamic testing parameters. Extracorporeal magnetic stimulation improves urodynamic parameters. Mirabegron improves daily incontinence episodes, nocturia, number of daily voids, and urine volume per void, whereas solabegron improves daily incontinence episodes. Short-term posterior tibial nerve stimulation is more efficacious than pelvic floor muscle training exercises and behavioral therapy for improving: urgency, urinary incontinence episodes, daily voids, volume per void, and overall quality of life. Sacral neuromodulation is more efficacious than antimuscarinic treatment for subjective improvement of overactive bladder and quality of life. Transvaginal electrical stimulation demonstrates subjective improvement in overactive bladder symptoms and urodynamic parameters. Multiple therapies, including physical therapy, behavioral therapy, botulinum toxin A, acupuncture, magnetic stimulation, mirabegron, posterior tibial nerve stimulation, sacral neuromodulation, and transvaginal electrical stimulation, are efficacious in the treatment of overactive bladder.

Work-related musculoskeletal disorders among vaginal surgeons

INTRODUCTION AND HYPOTHESIS

Work-related musculoskeletal disorders (MSDs) reportedly affect a large proportion of providers in obstetrics and gynecology. We hypothesize a high MSD prevalence rate among vaginal surgeons associated with surgeon- and work-related characteristics.

METHODS

Surveys were distributed to members of the International Urogynecological Association and American Urogynecological Society. Exclusion criteria included inability to read English, no computer access, invalid or unavailable e-mail address, and missing >50% of responses.

RESULTS

Among respondents, 86.7% (436/503) reported ever having work-related MSDs. On univariate analysis, surgeons involved in surgical teaching were significantly more likely to report work-related MSDs. Female surgeons had more frequent and more severe MSDs in the neck, dominant shoulder, and upper back. Older age and more years of work experience were associated with seeking medical attention. Right-hand dominance was associated with negative consequences on work behavior.

CONCLUSIONS

A large proportion of vaginal surgeon respondents reported work-related MSDs.

Male gender promotes an increased inflammatory response to lipopolysaccharide in umbilical vein blood

OBJECTIVES

To establish gender-specific differences in maternal and fetal immune response in healthy human fetuses at term.

METHODS

Forty-five women with elective caesarean sections for uncomplicated singleton pregnancies were recruited for two studies. Using a multiplex biomarker immunoassay system, unstimulated maternal and fetal plasma concentrations of interleukin (IL)-1β, IL-1ra, IL-6, IL-8, macrophage inflammatory protein (MIP)-1α, and tumor necrosis factor (TNF)-α were measured from one study population. Lipopolysaccharide (LPS)-stimulated cytokine response was measured in a second study.

RESULTS

There were no significant gender differences in either maternal or fetal unstimulated plasma cytokine concentrations, but concentrations of the proinflammatory cytokines IL-1β and IL-6 were significantly greater in male fetal LPS-stimulated samples than in female fetal samples.

CONCLUSIONS

Blood of male fetuses mounts a larger pro-inflammatory response to lipopolysaccharide (LPS). This heightened response could be a critical pathway in promoting premature rupture of membranes (PPROM) and may be associated with life long differential gender response to infection.
