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.
IntroductionPelvic organ prolapse (POP) is the descent of pelvic organs into the vagina resulting in bulge symptoms and occurs in approximately 50% of women. Almost 20% of women will elect surgical ...correction of this condition by age 85. Removal of the uterus (hysterectomy) with concomitant vaginal vault suspension is a long-standing practice in POP surgery to address apical (uterine) prolapse. Yet, contemporary evidence on the merits of this approach relative to preservation of the uterus through suspension is needed to better inform surgical decision making by patients and their healthcare providers. The objective of this study is to evaluate POP-specific health outcomes and service utilisation of women electing uterine suspension compared with those electing hysterectomy and vaginal vault suspension for POP surgery up to 1-year postsurgery.Methods and analysisThis is a prospective cohort study planning to enrol 321 adult women with stage ≥2 POP from multiple sites in Alberta, Canada. Following standardised counselling from study surgeons, participants self-select either a hysterectomy based or uterine preservation surgical group. Data are being collected through participant questionnaires, medical records and administrative data linkage at four time points spanning from the presurgical consultation to 1-year postsurgery. The primary outcome is anatomic failure to correct POP, and secondary outcomes include changes in positioning of pelvic structures, retreatment, subjective report of bulge symptoms, pelvic floor distress and impact, sexual function and health service use. Data will be analysed using inverse probability weighting of propensity scores and generalised linear models.Ethics and disseminationThis study is approved by the Conjoint Health Research Ethics Board at the University of Calgary (REB19-2134). Results will be disseminated via peer-reviewed publications, presentations at national and international conferences, and educational handouts for patients.Trial registration numberNCT04890951.
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.
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.
The sources for our data were MEDLINE, Cochrane, and clinicaltrials.gov databases from inception to January 2017.
We accepted randomized and nonrandomized studies of uterine-preserving prolapse surgeries compared with those involving hysterectomy.
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.
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.
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.
Abstract 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.
Introduction and hypothesis
Urine loss during recreational exercise is problematic. We aimed to characterize which activities are most frequently reported as causing leakage for women, adaptive ...management mechanisms, and awareness and interest in treatment in a cohort of physically active women.
Methods
We administered an anonymous questionnaire to 59 physically active women in Canada. Surveys were completed electronically or on paper. Demographic information was obtained. Questions about which specific activities caused leakage, adaptive behaviors to deal with urinary loss, and degree of bother were addressed, and knowledge and interest in therapies for leakage were queried.
Results
Activities most likely to cause leakage were skipping, trampoline, jumping jacks, and running/jogging. To decrease leakage, 93.2% voided immediately before exercise, 62.7% reported voiding breaks, and some reported fluid restriction (37.3%). Leakage impacted activity level for 50% of women. Most often, activity intensity was decreased (90.3%) or specific activities avoided (80.7%). Pad use during exercise was common (49.2%). Interest in receiving treatment for urinary incontinence (UI) was high (88.1%) despite a large proportion (35.6%) not knowing of available treatments. Interest was highest for pelvic floor physiotherapy (84.6%), although interest in both pessary and surgical management (63.5% each) was significant.
Conclusions
Women experiencing UI during exercise report high-impact activities as most frequently causing loss. Adaptive behaviors are common. Physically active women are interested in treatment, and the high interest in pelvic physiotherapy presents a unique opportunity to link pelvic exercise with recreational exercise to meet both cardiovascular and continence needs in the physically active patient population.
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.
To identify the optimal hysterectomy approach for large uteri in gynecologic surgery for benign indications from a perioperative morbidity standpoint.
PubMed and Embase databases were searched from ...inception through September 19, 2022. Meta-analyses were conducted as feasible.
This review included studies that compared routes of hysterectomy with or without bilateral salpingo-oophorectomy for large uteri (12 weeks or more or 250 g or more) and excluded studies with any concurrent surgery for pelvic organ prolapse, incontinence, gynecologic malignancy, or any obstetric indication for hysterectomy.
The review included 25 studies comprising nine randomized trials, two prospective, and 14 retrospective nonrandomized comparative studies. Studies were at high risk of bias. There was lower operative time for total vaginal hysterectomy compared with laparoscopically assisted vaginal hysterectomy (LAVH) (mean difference 39 minutes, 95% CI, 18-60) and total vaginal hysterectomy compared with total laparoscopic hysterectomy (mean difference 50 minutes, 95% CI, 29-70). Total laparoscopic hysterectomy was associated with much greater risk of ureteral injury compared with total vaginal hysterectomy (odds ratio 7.54, 95% CI, 2.52-22.58). There were no significant differences in bowel injury rates between groups. There were no differences in length of stay among the laparoscopic approaches. For LAVH compared with total vaginal hysterectomy, randomized controlled trials favored total vaginal hysterectomy for length of stay. When rates of blood transfusion were compared between these abdominal hysterectomy and robotic-assisted total hysterectomy routes, abdominal hysterectomy was associated with a sixfold greater risk of transfusion than robotic-assisted total hysterectomy (6.31, 95% CI, 1.07-37.32). Similarly, single studies comparing robotic-assisted total hysterectomy with LAVH, total laparoscopic hysterectomy, or total vaginal hysterectomy all favored robotic-assisted total hysterectomy for reduced blood loss.
Minimally invasive routes are safe and effective and have few complications. Minimally invasive approach (vaginal, laparoscopic, or robotic) results in lower blood loss and shorter length of stay, whereas the abdominal route has a shorter operative time.

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.
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.
