Technical Update on Pessary Use

A randomized clinical trial comparing internal and external pessaries in the treatment of pelvic organ prolapse in postmenopausal women: A pilot study

INTRODUCTION AND HYPOTHESIS

Internal vaginal pessary is among the leading treatments for pelvic organ prolapse (POP); however, it has a high adverse event rate. An external pessary was recently developed as an alternative. The study's objective was to compare the efficacy of external and internal pessaries in treating POP in postmenopausal women.

METHODS

This parallel randomized (1:1 ratio) open-blind study included 40 symptomatic women with stage 2 or 3 POP. They were randomized into two groups: group 1 (internal pessary) and group 2 (external pessary) (n = 20 in each); and evaluated at the start of and 3 months after the treatment. Statistical analysis was performed to compare the results within and between the groups before and after the 3-month treatment.

RESULTS

The groups were homogeneous, except for the variables previous pregnancies (p = 0.030) and POP-Q score of apical prolapse (p = 0.023) whose values were higher in group 2. A significant improvement in quality of life was observed in both groups after 3 months of follow-up; however, internal pessaries were found to be more effective (p < 0.001). In group 1 there were differences between the initial and final POP-Q scores of anterior (0.004) and apical prolapse (p = 0.005). The complication rate associated with internal pessary use was high (p = 0.044).

CONCLUSIONS

The present data suggested that external pessaries have a similar effect to internal ones for the treatment of POP and improvement of the quality of life of postmenopausal women.

Location and motion of vaginal pessaries in situ in women with successful and unsuccessful pessary treatment for pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

The objective was to compare the location and motion of pessaries between women with pelvic organ prolapse (POP) with a successful (fitting) and unsuccessful (non-fitting) pessary treatment on dynamic magnetic resonance imaging (dMRI).

METHODS

A cross-sectional exploratory study of 15 women who underwent a mid-sagittal dMRI of the pelvic floor at rest, during contraction and during Valsalva with three different types of pessaries. The coordinates of the pessaries cross section, inferior pubic point (IPP) and sacrococcygeal junction (SCJ) were obtained and the location (position, orientation) and the motion (translation and rotation) were calculated. Differences between the groups and between the pessaries within the groups were compared.

RESULTS

Nine women with a fitting pessary and 6 women with a non-fitting pessary were selected. In the non-fitting group, the pessaries were positioned more caudally and rotated more in clockwise direction and descended more, but not significantly, during Valsalva compared with the fitting group. The Falk pessary was positioned more anteriorly in the fitting group and more cranially in the non-fitting group compared with the ring and ring with support pessary.

CONCLUSIONS

A non-fitting pessary was positioned more caudally at rest; on Valsalva, it rotated more clockwise and moved more caudally, suggesting that the dynamic characteristics of the pessary might play an important role in its effectiveness. Findings of this study serve as a basis for the development of new pessary designs.

Vaginal Pessary Use and Management for Pelvic Organ Prolapse: Developed by the joint writing group of the American Urogynecologic Society and the Society of Urologic Nurses and Associates. Individual writing group members are noted in the Acknowledgments section

ABSTRACT

Over the past 50 years, pessary use has increased in popularity and has become an essential pelvic organ prolapse (POP) management tool. However, evidence is lacking to define care standardization, including pessary fitting, routine maintenance, and management of pessary-related complications. This clinical consensus statement (CCS) on vaginal pessary use and management for POP reflects statements drafted by content experts from the American Urogynecologic Society and Society of Urologic Nurses and Associates. The purpose of this CCS is to identify areas of expert consensus and nonconsensus regarding pessary fitting, follow-up, and management of pessary complications to improve the safety and quality of care where evidence is currently limited. The American Urogynecologic Society and Society of Urologic Nurses and Associates' vaginal pessary for POP writing group used a modified Delphi process to assess statements that were evaluated for consensus after a structured literature search. A total of 31 statements were assessed and divided into 3 categories: (1) fitting and follow-up, (2) complications, and 3) quality of life. Of the 31 statements that were assessed, all statements reached consensus after 2 rounds of the Delphi survey. This CCS document hopefully serves as a first step toward standardization of pessary care, but the writing group acknowledges that improved research will grow the base of knowledge and evidence providing clinicians a foundation to manage pessary care effectively and confidently.

Novel, disposable, self-inserted, vaginal device for the non-surgical management of pelvic organ prolapse: efficacy, safety, and quality of life

Background

We evaluated a novel disposable, collapsible, ring-shaped vaginal device that is self-inserted within an applicator and removed with a string. The device was developed to overcome the drawbacks of existing ring pessaries for non-surgical pelvic organ prolapse management (POP).

Methods

The primary objective efficacy endpoint of this prospective, interventional, multicenter, self-controlled, and home-use study was the proportion of subjects with improved staging on the Pelvic Organ Prolapse Quantification (POP-Q) scale. Subjective efficacy was assessed using the POP symptoms alleviation score. Safety was evaluated by recording the rate and incidence of adverse events (AEs) in a daily diary, and quality of life (QoL) was evaluated using the modified Pelvic Floor Impact (PFIQ-7) and Pelvic Floor Disability Index (PFDI-20) questionnaires.

Results

A total of 94 usage cycles were observed in a group of 52 participants (mean age 60.2 ± 10.5 years, 81.1% postmenopausal) who used the device for 3558 days. Of these, 24 participants completed one usage cycle, 14 completed two usage cycles, and 14 completed three usage cycles with 28–45 days of ProVate use in each usage cycle. All patients experienced greater than two POP-Q stage reductions. The descent was completely reduced to POP-Q stage 0 in 97.8% of participants. The POP symptom alleviation questionnaire showed significant subjective efficacy (P < 0.0001). The modified PFDI-20 and PFIQ-7 scores also improved substantially (P < 0.0001 for both). There were 91 nonserious device-related AEs: 98.9% were mild and 87.9% anticipated, with no vaginal infection, and one case of urinary tract infection.

Conclusion

The novel device substantially reduces prolapse and provides significant subjective POP symptom relief and QoL improvement, with minimal AEs. The device may enable women to self-manage their prolapse with a small, disposable device that minimizes self-touching and frequent dependency on the clinic.

The impact on complication rates of delayed routine pessary reviews during the COVID-19 pandemic

Introduction and hypothesis

During the COVID-19 pandemic, guidance was issued in the United Kingdom advising a delay in routine pessary reviews. The impact of this has not been fully explored. The null hypothesis for this study is that delayed routine pessary reviews during the COVID-19 pandemic did not result in a statistically significant increase in complication rate.

Methods

A retrospective comparative cohort study was conducted in NHS Tayside, Scotland, involving 150 patients pre-pandemic and 150 patients during the COVID-19 pandemic (before exclusions). Their notes were reviewed identifying age, care provider, pessary type, length of pessary usage, review date, time elapsed since the previous review, bleeding/infection/ulceration, removal issues, pessary replacement and outcome. Patients excluded were those with no pessary in situ at review, reviews at ≤4 months and >8 months (pre-pandemic) and reviews at ≤8 months (COVID-19 pandemic).

Results

The pre-pandemic group (n=106) had average review times of 10.1,6.2 and 6.2 months for cubes, rings and all others. Overall rates of bleeding/infection/ulceration; reported removal issues; and pessary subsequently not replaced were 9.4%, 11.3% and 5.7% respectively. The COVID-19 pandemic group (n=125) had average review times of 14.7, 10.8 and 11.4 months for cubes, rings and all others. Overall rates of bleeding/infection/ulceration; reported removal issues; and pessary subsequently not replaced were 21.6%, 16.0%, and 12.0% respectively.

Conclusions

Overall, there was a significant increase in rates of bleeding/ulceration/infection (p=0.01). When individual pessaries were considered, this only remained true for rings (p=0.02). Our data would suggest that routine ring pessary reviews should not be extended beyond 6 months or risk bleeding/ulceration/infection.

Current State of Non-surgical Devices for Female Stress Urinary Incontinence

PURPOSE OF REVIEW

The purpose of this review is to summarize and assess the current non-surgical devices for the treatment of stress urinary incontinence (SUI).

RECENT FINDINGS

Devices for SUI can generally be divided into two categories. One category is the augmentation of pelvic floor muscle training (PFMT), wherein devices such as vaginal cones, intravaginal biofeedback, and electrical or magnetic stimulation are used to strength the pelvic floor musculature, though none are more effective than traditional PFMT. The second category of devices mechanically occludes the outlet and includes incontinence pessaries, intravaginal occlusion devices, and urethral plugs and patches. While these are palliative rather than curative, they share similar rates of improvement in leakage. A number of novel devices exist for the treatment and management of SUI. Though no single device has been shown to be more effective than PFMT alone, they may be beneficial for women who have difficulty isolating their pelvic floor muscles, desire accountability, or prefer technology-based engagement. Outlet occlusion devices are less comfortable for the patient, but remain an option for women who do not desire surgery.

Rare complications of pessary use: A systematic review of case reports

Introduction

Pessaries are desirable for its overall safety profiles. Serious complications have been reported; however, there is little summative evidence. This systematic review aimed to consolidate all reported serious outcomes from pessaries usage to better identify and counsel patients who might be at higher risk of developing these adverse events.

Methods

We performed a systematic literature review using search terms such as ‘prolapse’, ‘stress urinary incontinence’ and ‘pessary or pessaries or pessarium’ on PubMed, Embase and CINAHL. A total of 36 articles were identified. Patient‐level data were extracted from case reports to further describe complications on an individual level.

Results

Overall median age of the patients was 82 years (range 62–98). The most frequent complications were vesicovaginal fistula (25%, n = 9/36), rectovaginal fistula (19%, n = 7/36), vaginal impaction (11%, n = 4/36) and vaginal evisceration of small bowel through vaginal vault (8%, n = 3/36). In the vesicovaginal fistula cohort, none of the patients had a history of radiation, and two had histories of total abdominal hysterectomy (22%). In the rectovaginal fistula cohort, one patient had a history of pelvic radiation for rectal squamous cell carcinoma, and another had a history of chronic steroid use for rheumatoid arthritis. No other risk factors were reported in the other groups. Ring and Gellhorn were the most represented pessary types among the studies, 16 (44%) and 12 (33%), respectively. No complications were reported with surgical and non‐surgical treatment of the complications.

Conclusion

Pessaries are a reasonable and durable treatment for POP with exceedingly rare reports of severe adverse complications. The ideal candidate for pessary should have a good self‐care index. Studies to determine causative factors of the more serious adverse events are needed; however, this may be difficult given the long follow‐up that is required.

Effect of estrogen on vaginal complications of pessary use: a systematic review and meta-analysis

OBJECTIVE

We aimed to systematically review the impact of local estrogen use in combination with a pessary on vaginal complications in postmenopausal women with pelvic organ prolapse (POP).

METHODS

We searched databases including Medline, Embase, PubMed, Clinical Trials and the Cochrane Central Register of Controlled Trials for relevant literature published in English from inception to 31 May 2021. Only randomized controlled trials (RCTs) and cohort studies were included.

RESULTS

In total, five studies were included (three RCTs, one prospective study and one retrospective cohort study). The meta-analysis was performed with subgroups. Our results indicated a significantly lower incidence of bacterial vaginosis (BV) among postmenopausal women who used estrogen than among controls, with a total pooled odds ratio (OR) of 0.29 (95% confidence interval [CI]: 0.11-0.72; I² = 38%; p = 0.008). The summary ORs of the estrogen use group were 0.98 (95% CI: 0.59-1.63; I² = 41%; p = 0.95) for vaginal ulceration, 0.80 (95% CI: 0.42-1.54; I² = 29%; p = 0.50) for vaginal bleeding and 0.74 (95% CI: 0.35-1.58; I² = 35%; p = 0.44) for vaginal discharge.

CONCLUSIONS

Local estrogen in combination with a pessary could decrease the BV rate among postmenopausal women with POP. However, consensus regarding the value of estrogen use for decreasing other pessary complications has not yet been reached. Additional multicenter RCTs with large sample sizes should be conducted to better understand the effect of estrogen use on reducing pessary-related complications.

The Role of Pessaries in the Treatment of Women With Stress Urinary Incontinence: A Systematic Review and Meta-Analysis

IMPORTANCE

Pessaries are an important conservative therapy for stress urinary incontinence (SUI), but few studies have comprehensively evaluated their utility.

OBJECTIVE

The objective of this study is to evaluate the existing evidence on the efficacy and safety of pessaries for the treatment of SUI.

STUDY DESIGN

We searched for the terms "stress urinary incontinence" and "pessar/y/ies/ium" in PubMed, Embase, and Cinhal on June 10, 2020. Studies that characterized subjective and/or objective data were included. Studies performed in pediatric populations, pregnancy, and use of pessaries not for SUI were excluded. Two reviewers independently screened and assessed data quality and risk of bias according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

RESULTS

Ten studies, including 376 patients, were included. In terms of subjective outcomes, 76% of 72 patients reported feeling continent after pessary treatment compared with 0% of 86 patients surveyed before pessary use (P < 0.0001). Both Urinary Distress Inventory and Incontinence Impact Questionnaire scores decreased significantly by 46.7% (n = 155 baseline, n = 139 follow-up; P < 0.0001) and 67.8% (n = 139 baseline, n = 107 follow-up; P < 0.0001), respectively. Significant objective measures associated with pessary use included increased urethral closure pressure (n = 122; g = 0.56; 95% confidence interval [CI], -0.66 to 1.77; P < 0.049) and decreased pad weight (n = 129 baseline; n = 118 follow-up; g = -0.89; 95% CI, -1.986 to 0.19; P = 0.009). Adverse events significantly decreased at greater than 6 months follow-up compared with less than 6 months follow-up, including pain (31.5%, n = 29/92 vs 14.3%, n = 5/35; P = 0.0513) and discomfort (50%, n = 46/92 vs 29.3%, n = 12/41; P = 0.0268).

CONCLUSIONS

Based on both subjective and objective measures, pessaries are an effective conservative treatment option for SUI. This supports pessary use, though larger studies with longer-term follow-up are warranted.

Position and orientation of vaginal pessaries in situ on magnetic resonance imaging

INTRODUCTION AND HYPOTHESIS

We hypothesize that there are differences in the position and orientation of ring and Gellhorn pessaries in situ on magnetic resonance imaging (MRI).

METHODS

This was a retrospective cohort study comparing MRI findings in 25 women with pessaries in situ at the time of imaging. Scanner coordinates for anatomic and pessary landmarks were obtained and transformed to 3D Pelvic Inclination Correction System coordinates using MATLAB software. The normal vector to the pessary disc was computed and compared to the positive y-axis in the sagittal and coronal planes to determine XY and YZ disc angles, respectively. Comparisons between groups were made using Wilcoxon rank, Fisher's exact, and Brown-Forsythe tests.

RESULTS

Twenty-one women with ring pessaries and four women with Gellhorn pessaries met inclusion criteria for the study. Women with ring pessaries were younger (68.4 vs. 80.7 years, p = 0.003) but had similar BMI, vaginal parity, history of hysterectomy, and anatomic characteristics. Ring pessaries had a smaller diameter (59.5 vs. 79.3 mm, p = 0.004) and were positioned further posterior with respect to the inferior pubic point (midpoint X position 42.6 vs. 29.5 mm, p = 0.004). There were significant differences in the magnitude and variance of the XY disc angle (57.0 ± 14.0 vs. -1.2 ± 2.8 degrees, p = 0.002 for magnitude, p = 0.012 for variance) but not the YZ disc angle (3.3 ± 30.6 vs. 1.5 ± 7.7 degrees, p > 0.05 for both) between groups.

CONCLUSIONS

We found differences in the position and orientation between ring and Gellhorn pessaries in situ using an anatomic 3D reference system. These findings provide insight into the mechanism of action of vaginal pessaries.

Host inflammatory response in women with vaginal epithelial abnormalities after pessary use

BACKGROUND

Vaginal epithelial abnormalities (VEA) are a common complication associated with pessary use. The objective of this study was to determine if there is a host pro-inflammatory response associated with pessary use and VEA.

METHODS

Patients wearing pessaries for at least two weeks for the management of pelvic organ prolapse and/or urinary incontinence were screened for eligibility. Vaginal swabs were collected from women with VEA (cases) and without VEA (controls). Cases were matched to controls in a 1:3 ratio. Cytokine analysis of the collected samples was performed using multiplex analysis to determine the concentrations of interleukin (IL)6, interferon alpha 2 (IFNα2), tumor necrosis factor alpha (TNFα) and IL1β. A cross-sectional analysis was performed, comparing vaginal cytokine concentrations in women with and without VEA.

RESULTS

We enrolled 211 patients in this analysis: 50 cases and 161 controls. The median concentrations (pg/mL) of the four cytokines for cases and controls respectively were; IL6: 6.7 (IQR <2.9 [the lower limit of detection, LLD]-14.2) and < 2.9 (LLD) (IQR <2.9 [LLD]-5.5), IFNα2: 8.2 (IQR 6.1-13.9) and 7.9 (IQR 3.9-13.6), TNFα: 15.2 (IQR 6.1-30.4) and 4.68 (IQR <2.3 [LLD]-16.3), IL1β 195.7 (IQR 54.5-388.6) and 38.5 (IQR 6.7-154.9). The differences in median cytokine levels were statistically higher in cases for IL6, TNFα, and IL1β (all p < 0.001) compared to controls. Older age (OR: 1.062, 95% CI, 1.015-1.112), lower BMI (OR: 0.910, 95% CI, 0.839-0.986) and presence of VEA at last check (OR: 5.377, 95% CI, 2.049-14.108) were associated with higher odds of having VEA on multivariate analysis.

CONCLUSION

Pro-inflammatory cytokines, specifically IL6, TNFα, and IL1β, are elevated in pessary-wearing patients who have VEA. Additional prospective studies are needed to assess baseline vaginal inflammatory profiles before and after pessary placement to understand VEA formation in pessary patients.

Personalised urethra pessaries prepared by material extrusion-based additive manufacturing

Material extrusion-based additive manufacturing, commonly referred to as 3D-printing, is regarded as the key technology to pave the way for personalised medical treatment. This study explores the technique's potential in customising vaginal inserts with complex structures, so-called urethra pessaries. A novel, flawlessly 3D-printable and biocompatible polyester-based thermoplastic elastomer serves as the feedstock. Next to the smart selection of the 3D-printing parameters cross-sectional diameter and infill to tailor the pessary's mechanical properties, we elaborate test methods accounting for its application-specific requirements for the first time. The key property, i.e. the force the pessary exerts on the urethra to relief symptoms of urinary incontinence, is reliably adjusted within a broad range, including that of the commercial injection-moulded silicone product. The pessaries do not change upon long-term exposure to vaginal fluid simulant and compression (in-vivo conditions), satisfying the needs of repeated pessary use. Importantly, the vast majority of the 3D-printed pessaries allows for self-insertion and self-removal without any induced pessary rupture. Summarising, 3D-printed pessaries are not only a reasonable alternative to the commercial products, but build the basis to effectively treat inhomogeneous patient groups. They make the simple but very effective pessary therapy finally accessible to every woman.

Pessaries and rectovaginal fistulae: consequences of delayed clinical follow-up in the Covid-19 pandemic

Introduction and hypothesis

While 2017 guidelines from The American College of Obstetricians & Gynecologists called for pessary replacement every 3 to 4 months, a recent study in Obstetrics and Gynecology suggested that uninterrupted pessary use up to 6 months is not an independent risk factor for development of pessary-related complications.

Methods

Our recent experience throughout the Covid-19 pandemic highlights the potential ramifications of delayed clinical follow-up.

Results

During the Covid-19 pandemic, 3 of our patients developed rectovaginal fistulae secondary to Gellhorn pessary erosion in the context of delayed clinical follow-up. Our patients had previously attended routine appointments every 3 months without complications until missed appointments secondary to the pandemic led to fistulae formation.

Conclusion

We believe that delayed clinical follow-up of pessary management beyond 3 months due to the Covid-19 pandemic may lead to fistula complications in elderly women with Gellhorn pessaries.

Novel polyester-based thermoplastic elastomers for 3D-printed long-acting drug delivery applications

To improve patient compliance and personalised drug delivery, long-acting drug delivery devices (LADDDs), such as implants and inserts, greatly benefit from a customisation in their shape through the emerging 3D-printing technology, since their production usually follows a one-size-fits-most approach. The use of 3D-printing for LADDDs, however, is mainly limited by the shortage of flawlessly 3D-printable, yet biocompatible materials. The present study tackles this issue by introducing a novel, non-biodegradable material, namely a polyester-based thermoplastic elastomer (TPC) - a multi-block copolymer containing alternating semi-crystalline polybutylene terephthalate hard segments and poly-ether-terephthalate amorphous soft segments. Next to a detailed description of the material's 3D-printability by mechanical, rheological and thermal analyses, which was found to be superior to that of conventional polymers (ethylene-vinyl acetates (EVA)), this study establishes the fundamental understandings of the interactions between progesterone (P4) and TPC and drug-releasing properties of TPC for the first time. P4-loaded LADDDs based on TPC, prepared via an elaborated solvent-immersion technique, enable the release of P4 at pharmacologically relevant rates, similar to those of marketed formulations based on EVA and silicones. Additionally, TPC demonstrated an exceptional 3D-printability for a wide selection of implant sizes and complex geometries.

Pathophysiology of Vaginal Erosions in Women Using Pessary: A Pilot Study Examining Vaginal Microbiota

OBJECTIVE

Many women with pelvic organ prolapse opt for a pessary, and some of these women develop erosions of the vaginal mucosa. Ongoing erosions might lead to the discontinuation of this otherwise effective, non-invasive, and inexpensive treatment. The objectives of this study were to investigate the differences in vaginal pH and variations of the vaginal microbiota among pessary and non-pessary users.

METHODS

For this descriptive observational study, 30 women, followed in our urogynecology clinic, were recruited to form 3 equal groups: 2 groups of women using a pessary (with and without erosions) and 1 control group of women not using a pessary. Vaginal pH was measured distally and next to the erosion. Vaginal swabs were used to investigate the vaginal microbiota by sequencing the V4 region of the 16S ribosomal RNA gene and analyzing the data with Qiime2. Descriptive statistics were reported using the median values. Vaginal pH comparisons between groups were made using a Kruskal-Wallis test with Dunn's correction for multiple comparisons.

RESULTS

The pH of the vagina was more alkaline in women with erosions compared with women in the other 2 groups (P < 0.01). Also, the pH of the distal vagina was not different from the pH next to the erosion (P = 0.25). Patients with erosions displayed significant differences in their vaginal microbiota, which contained a much greater bacterial diversity with an increase in gram-negative bacteria (e.g., Bacteroidetes, Actinobacteria) and a decrease in lactobacilli.

CONCLUSION

In our study, women with vaginal erosions had significantly higher vaginal pH and more complex vaginal microbiota than women in the control groups. Treatments focusing on lowering the vaginal pH and/or re-establishing the vaginal microbiota should be considered.

Knowledge of pelvic floor disorders amongst immigrant women in Canada

INTRODUCTION AND HYPOTHESIS

Pelvic floor disorders (PFD) have a detrimental effect on quality of life. Despite the available treatments, women often do not seek medical care. Patient knowledge has been identified as a major barrier to accessing care. The objective of this study was to assess knowledge on PFD amongst women in Edmonton, hypothesizing that immigrant women are less knowledgeable about PFD than Canadian-born women.

METHODS

A cross-sectional study of immigrant women and Canadian-born women was conducted. Immigrant women were recruited at the Multi-Cultural Health Brokers Co-op (MCHB) and Canadian-born women at a colposcopy clinic. The Prolapse and Incontinence Knowledge Questionnaire (PIKQ) was administered. Scores for UI and POP were calculated and compared using a Mann-Whitney U test and a t test. A subgroup analysis of immigrants was carried out according to length of stay in Canada and ethnicity. Ethics approval was obtained from the University of Alberta Human Research Ethics Office.

RESULTS

A total of 106 immigrants and 102 Canadian-born women completed the PIKQ. The overall PIKQ scores were 12.7 for immigrant women and 14.4 for Canadian-born women (p = 0.04). Immigrant women who had lived in Canada for >10 years had higher scores (mean = 13.2) compared with women with less than 10 years in Canada (mean = 11.8). Women from South Asia had higher overall PIKQ scores (mean = 14.6) whereas women from sub-Saharan Africa had the lowest scores (mean = 12.1).

CONCLUSIONS

Immigrant women in Edmonton were found to have less knowledge on PFD than Canadian-born women.

ESTROgen use for complications in women treating pelvic organ prolapse with vaginal PESSaries (ESTRO-PESS)-a randomized clinical trial

INTRODUCTION AND HYPOTHESIS

To evaluate the complications of new users' vaginal pessaries (VP), with and without the use of vaginal estrogen after a 6-month follow-up.

METHODS

A parallel, single-blinded, randomized, controlled trial. Symptomatic postmenopausal women (n = 98) with pelvic organ prolapse (POP) (stage 3/4) were recruited from August 2018 to October 2019. Patients were randomized into the local estrogen group (promestriene 3 × for a week) and the control group (no estrogen). They were evaluated for their vaginal symptoms at the baseline, after 3 months, and after 6 months, and a physical examination and vaginal sampling for microbiological analysis were done. Data were analyzed according to an intention-to-treat analysis (ITT). A 5% significance level was established for statistical analysis.

RESULTS

Twenty women discontinued treatment (20.4%), mainly due to pessary extrusion (n = 15) and 5 for other reasons (lost to follow-up, pain, and surgery). Baseline characteristics were not statistically different between the estrogen and control groups. Regarding the presence of complications, the presence of erosion was 10% in the control group, but there was no significant difference between the groups (p = 0.175) after 6 months. Bacterial vaginosis (BV) was more prevalent in the control group, according to the Nugent (p = 0.007) and Amsel (p = 0.014) criteria. Urinary urgency and increased urinary frequency were significantly improved in the estrogen group after 6 months.

CONCLUSION

There was no evident benefit related to complications such as ulcerations, itching, and vaginal discharge/odor from the use of vaginal estrogen in POP women using pessaries.

Pessary evaluation for genital prolapse treatment: From acceptance to successful fitting

AIMS

To determine the percentage of women with symptomatic pelvic organ prolapse who opted for pessary and had a successful pessary fitting trial; to identify the most commonly used size of pessary for stage of prolapse; and to identify risk factors associated with unsuccessful fitting.

METHODS

We conducted a prospective cohort study of women with symptoms of genital prolapse referred to a public hospital tertiary care clinic (2013-2019). We used ring and ring with support pessaries for fittings. We collected patient demographics, pelvic organ prolapse quantification, size of pessary used and evaluated factors associated with pessary fittings. We defined unsuccessful fit as failure to continue pessary use at 4 weeks post fitting trial. We used Mann-Whitney and χ² tests to compare variables between groups of successfully and unsuccessfully fitted. Using logistic regression, we built a prediction model for unsuccessful fit.

RESULTS

All 170 women with symptomatic prolapse referred to our clinic accepted to undergo a pessary fitting. More than 70% (n = 124/72.9%) were successfully at 4 weeks. We used an average of 1.7 pessaries (range: 1-6) per patient to identify the best-fitting pessary and #2, 5, 3, 7, and 4 were the sizes commonly used (78.2%). Women with body mass index ≥30 kg/m² (odds ratio [OR]: 4.74; 95% confidence interval [CI], 1.98-11.32; P < .001), total vaginal length <7.5 cm (OR: 3.78; 95% CI, 1.98-11.32; P < .001), and sexually active women (OR: 2.26; 95% CI, 1.04-4.91; P = .035) were associated with increased unsuccessful fitting.

CONCLUSION

The vaginal pessary proved to be an excellent choice, with high acceptance and successful fitting rates.

Pelvic Organ Prolapse: ACOG Practice Bulletin, Number 214

Pelvic organ prolapse (POP) is a common, benign condition in women. For many women it can cause vaginal bulge and pressure, voiding dysfunction, defecatory dysfunction, and sexual dysfunction, which may adversely affect quality of life. Women in the United States have a 13% lifetime risk of undergoing surgery for POP (). Although POP can occur in younger women, the peak incidence of POP symptoms is in women aged 70-79 years (). Given the aging population in the United States, it is anticipated that by 2050 the number of women experiencing POP will increase by approximately 50% (). The purpose of this joint document of the American College of Obstetricians and Gynecologists and the American Urogynecologic Society is to review information on the current understanding of POP in women and to outline guidelines for diagnosis and management that are consistent with the best available scientific evidence.

Women and healthcare providers' knowledge, attitudes and practice related to pessaries for pelvic organ prolapse: A Systematic review

OBJECTIVE

To identify the knowledge, attitudes and practice of women and healthcare professionals in relation to pessary use for POP.

METHOD

This systematic review was carried out in agreement with PRISMA recommendations. PubMed/MEDLINE, SCOPUS, Virtual Health Library, Web of Science, CAPES Periodicals and CINAHL databases were searched for studies without date or language limitations. Search strategies were developed for identifying studies examining knowledge, attitudes and practice toward vaginal pessaries use. Two reviewers independently screened titles and abstracts to identify eligible studies. Data extraction was performed independently in duplicate into a standardized form. Quality of included studies was assessed using the Joanna Briggs Institute quality assessment tool. The protocol was registered with the PROSPERO International prospective register of systematic reviews [CRD42018114236].

RESULTS

Fourteen studies were included. Knowledge and practice were the main domains investigated among patients and professionals, respectively. The results demonstrated poor patient knowledge; however, in urogynecologic patients, knowledge was better. Previous consultation with a Female Pelvic Medicine and Reconstructive Surgery specialist (p = .001) and a higher level of education (p = .006) were associated with improved knowledge of pessary use. Fear of vaginal discharge, irritation, bleeding, and pain were factors that supported the decision not to use a pessary. Previous consultation with a generalist gynecologist (p = .03)and a lower level of education (p = .03) predicted aversion to pessary use. Providers demonstrated adequate knowledge and recommended pessary in 86.4% to 98.0% of cases. Having specialist and pessary management training were some factors that influenced a better attitude towards pessaries among health professionals.

CONCLUSION

The knowledge, attitudes and practice of women and health care providers about pessary use are seldom investigated. Developing a psychometrically valid instrument for assessment of knowledge, attitudes and practice is desirable to examine the complex interactions between these three constructs, expose barriers to pessary care, and develop targeted educational interventions.

Revisiting current treatment options for stress urinary incontinence and pelvic organ prolapse: a contemporary literature review

Stress urinary incontinence (SUI) and pelvic organ prolapse (POP) affect many women in their lifetime. In this review, we describe and evaluate the latest treatment options for SUI and POP, including the controversy around transvaginal mesh (TVM) use. Growing evidence supports the utilization of pelvic floor muscle training as first-line treatment for both SUI and POP. Vaginal pessaries continue to be an effective and reversible option to manage SUI and POP symptoms. The midurethral sling remains the gold standard for surgical treatment of SUI, although patients and clinicians should acknowledge the potentially serious complications of TVM. Burch urethropexy and pubovaginal sling offer good SUI cure and may be preferred in women wishing to avoid mesh implants; however, their operative morbidities and more challenging surgical approach may limit their use. Site-specific cystocele or rectocele repairs may be indicated for isolated anterior or posterior vaginal compartment prolapse; however, in women with more severe POP, evidence supports using a vaginal native-tissue repair involving apical suspension as the primary surgical technique. Although abdominal and laparoscopic sacrocolpopexies are both effective in treating POP, their failure and mesh complication rates increase with time. There is insufficient evidence to support the widespread use of uterine-preserving surgical POP repairs at present due to the lack of long-term data. Routine TVM use is not recommended in POP surgeries and should only be considered on a case-by-case basis by trained surgeons, primarily in women with multiple risk factors for POP recurrence. In general, clinicians should individualize SUI and POP treatment options for women based on their symptoms, comorbidities, and risk factors for mesh-related complications.

Pessários vaginais na incontinência urinária: revisão integrativa

Objetivo: Analisar os tipos de pessários, as indicações e o impacto no tratamento da incontinência urinária (IU). Métodos: Trata-se de revisão integrativa com publicações de 2007 a 2017 indexadas nas bases de dados Biblioteca Virtual em Saúde, Medical Literature Analysis and Retrieval System Online, Scopus Info Site, Cumulative Index to Nursing and Allied Health Literature e Web of Science. Resultados: Selecionaram-se oito artigos. Os pessários indicados foram prato, anel, Uresta® e Contiform®. A redução ou resolução da IU de esforço (IUE) em mulheres foi observada por análise de parâmetros objetivos, como avaliação urodinâmica e questionários de qualidade de vida. Destacou-se viabilidade econômica. Evidenciaram-se desajuste, dificuldades no uso, incômodo e manutenção de perdas urinárias entre os motivos de não adesão. Prolapso avançado e comprimento vaginal curto foram preditivos de insucesso. Identificaram-se eventos adversos em baixa incidência: retenção urinária e leucorreia. Conclusão: A terapia pessária é eficaz no tratamento da IUE quando acompanhada por profissionais capacitados. Características individuais e percepções sobre o dispositivo são determinantes no sucesso terapêutico. Estudos de maior amostragem, tempo de seguimento e qualidade, bem como estimulo a publicações nacionais, são necessários para investigação de medidas objetivas de IU, fatores clínicos e demográficos em relação ao sucesso do pessário.

Vaginal pessaries in urinary incontinence: integrative review

Objectives: To analyze the types of pessaries, indications and impact in the treatment of urinary incontinence (UI). Methods: This is an integrative review with publications from 2007 to 2017 indexed in the Biblioteca Virtual em Saúde, Medical Literature Analysis and Retrieval System Online databases, Scopus Info Site, Cumulative Index to Nursing and Allied Health Literature and Web of Science. Results: Eight articles were selected. The pessaries indicated were the dish, ring, Uresta®, and Contiform®. The reduction or resolution of stress UI in women was observed by analysis of objective parameters such as urodynamic evaluation and quality of life questionnaires. Economic viability was highlighted. Disability, difficulties in use, discomfort, and maintenance of urinary losses were evidenced among the reasons for non-adherence. Advanced prolapse and short vaginal length were predictive of failure. Adverse events were identified in low incidence: urinary retention and leukorrhea. Conclusion: Pessary therapy is effective in the treatment of SUI when accompanied by trained professionals. Individual characteristics and perceptions about the device are determinants of therapeutic success. Studies of greater sampling, follow-up time and quality, as well as stimulation to national publications, are necessary for the investigation of objective measures of UI, clinical and demographic factors in relation to the success of the pessary.

What Are the Clinical Factors That Are Predictive of Persistent Pessary Use at 12 Months?

OBJECTIVE

Urinary incontinence and pelvic organ prolapse are highly prevalent in women and have a significant impact on quality of life. Pessaries are devices that are used as a conservative management option. Many women use pessaries, which avoid surgical intervention with its associated morbidity and cost. However, not all women are good candidates for pessary use. The objective of this study was to determine clinical factors leading to persistent pessary use for incontinence or pelvic organ prolapse in a tertiary care centre at 12 months. Studying patient characteristics for long-term pessary use will contribute to better patient counselling, management, and health resource distribution.

METHODS

This study was a retrospective outpatient chart review of new pessary fittings in patients in a tertiary care urogynaecology clinic between January and June 2014. Any woman over 18 years of age fitted with a pessary at that time was included in the study. All statistical analyses were performed using IBM SPSS Statistics version. 24 (IBM Corp., Armonk, NY) (Canadian Task Force Classification II-3).

RESULTS

A total of 152 women were fitted with pessaries. A multivariable logistic regression analysis found that a patient's diagnosis of prolapse or incontinence (P = 0.01) and a lack of complications (P < 0.0001) were statistically significant for persistent pessary use at 12 months. Patients with prolapse had 7.7 times higher odds (95% CI 1.51-39.35) of using a pessary at 12 months than did patients with incontinence. Patients without complications had 250 times higher odds (95% CI 18.52-2500) of pessary use. Patients who tried two to three pessaries had 16 times higher odds (95% CI 1.80-137.00) of persistent use than patients who trialed just one.

CONCLUSION

This study has found that a lack of complications, the number of pessaries tried, and a primary diagnosis of prolapse are significant factors for continued pessary use at 12 months.

Quality of life and vaginal symptoms of postmenopausal women using pessary for pelvic organ prolapse: a prospective study

SUMMARY OBJECTIVE: The use of pessary is an option for the conservative treatment of pelvic organ prolapse (POP). However, here are few studies assess the quality of life (QoL) after inserting the pessary for POP. We have hypothesized that the use of pessary would modify QoL in women with POP. METHODS: A prospective, observational study was performed that included 19 women with advanced POP. Pessary was introduced, and the SF-36 (general quality of life) and ICIQ-VS (vaginal symptoms and quality of life subdomain) questionnaires were applied before the introduction and after six months. A single question about the satisfaction regarding the use of the device was presented (subjective impression). RESULTS: The mean age of the women included was 76 years. Most of them were non-caucasian (52.6%), with no prior pelvic surgery (57.5%), with urinary symptoms (78.9%). A third of the patients reported sexual activity. After treatment, 22.2% of them presented vaginal infection, and 27.7% increased vaginal discharge. Urinary symptoms remained unaltered. Women reported 100% satisfaction after using the pessary (77.7% partial improvement; 22.3% total improvement). SF-36 had significant improvement in three specific domains: general state of health (p=0.090), vitality (p=0.0497) and social aspects (p=0.007). ICIQ-VS presented a reduction in the vaginal symptoms (p < 0.0001) and an improvement in QoL (P < 0.0001). CONCLUSION: The use of pessary for six months improved the QoL and reduced vaginal symptoms for women with advanced POP.

Defecatory dysfunction and other clinical variables are predictors of pessary discontinuation

INTRODUCTION AND HYPOTHESIS

Pessaries provide first-line therapy for women with pelvic organ prolapse (POP) and stress urinary incontinence (SUI). The primary hypothesis was that defecatory dysfunction was associated with pessary discontinuation.

METHODS

This was a retrospective cohort study of all women undergoing first pessary placement at one academic center from April 2014 to January 2017. Defecatory dysfunction was defined as the presence of constipation, rectal straining, rectal splinting, and/or incomplete defecation. Pessary discontinuation was defined as <1 year of pessary use and not using one at the most recent visit. Descriptive statistics; Person's chi-square, Fisher's exact, and Student's t test, and multivariate logistic regression analysis were used where appropriate.

RESULTS

Charts of 1092 women were reviewed and 1071 were included. Mean age was 62 ± 15 years, mean body mass index (BMI) 28 ± 6 kg/m², and mean parity 2 ± 1; 68% were Caucasian, 73% were menopausal, and 41% were sexually active. Reason for pessary use included POP (46%), SUI (24%), or both (30%). Overall pessary discontinuation rate was 77%; overall rate of defecatory dysfunction was 45%. In a logistic regression model, defecatory dysfunction in the form of incomplete defecation remained significantly associated with pessary discontinuation [odds ratio (OR) 3.29, 95% confidence interval (CI) 1.43-7.52]. Absence of bulge symptoms (OR 2.18, 95% CI 1.22-3.90), and younger age (OR 1.02, 95% CI 1.02-1.05) also remained significantly associated with pessary discontinuation.

CONCLUSIONS

Pessary discontinuation was common, and defecatory dysfunction in the form of incomplete defecation had the strongest association with discontinuation. Understanding predictive factors of pessary discontinuation may help guide clinicians and patients when choosing treatment options for pelvic floor dysfunction.

Documenting pessary offer prior to hysterectomy for management of pelvic organ prolapse

OBJECTIVES

To (1) determine the proportion of hysterectomy cases with documentation of pessary counseling prior to prolapse surgery and (2) identify variables associated with women offered a pessary.

STUDY DESIGN

The Michigan Surgical Quality Collaborative (MSQC) is a hysterectomy improvement initiative. Hysterectomies from 2013 to 2015 in which prolapse was the principal diagnosis were included. "Pessary offer" was defined as documentation showing the patient declined, could not tolerate, or failed a pessary trial. Bivariate analyses were used to compare demographics, medical history, surgical route, concomitant procedures (colpopexy or colporrhaphy), and intra- and postoperative complications between women with and without pessary offer. Hierarchical logistic regression was used to determine factors independently associated with pessary offer. Risk-adjusted pessary offer rates by hospital were calculated.

RESULTS

The adjusted rate of pessary offer was 25.2%, ranging from 3 to 76% per hospital. Bivariate comparisons showed differences between women with and without pessary offer in age, tobacco use, prior pelvic surgery, insurance status, surgical approach, secondary indication for surgery, concomitant prolapse procedure, teaching hospital status and hospital bed size. In logistic regression, odds of pessary offer increased with age > 55 years (OR 1.45, 95% CI 1.12-1.88, p = 0.006), Medicare insurance (OR 1.65, 95% CI 1.30-2.10, p < 0.0001), and a concomitant procedure (OR 1.5, 95% CI 1.16-1.93, p = 0.002). Postoperative urinary tract infections were more common in patients offered a pessary (6.4% vs. 2.5%, p < 0.0001), but other complications were similar.

CONCLUSIONS

Overall, only one-quarter of hysterectomies for prolapse in MSQC hospitals had documentation of pessary counseling-suggesting an opportunity to improve documentation, counseling regarding pessary use, or both.

Does general experience affect self-assessment?

BACKGROUND

The assessment of clinical competence is critical in medical education. Understanding the effect of general experience on a physician's self-assessment would help design more effective curricula and evaluations of procedural skills in postgraduate training and continuing professional development (CPD). In this observational study, we assessed the effect of general experience on the correlation between confidence and competence amongst experienced clinicians (ECs) and postgraduate trainees (PGTs) when learning an office-based procedure in pessary care.

METHODS

We recruited 19 first-year family medicine residents and 18 family medicine faculty members in two outpatient academic clinics. All participants attended a simulation-based workshop for a routine gynaecological office procedure. We used a confidence survey as a measure of the participants' self-assessed competence and an objective structured clinical examination (OSCE) to evaluate participants' competence before and after the workshop. The assessment of clinical competence is critical in medical education RESULTS: We found no significant correlation between confidence and competence at baseline for either group (EC, r = 0.25, p = 0.35; PGT, r = 0.15, p = 0.60). After the workshop, we observed a statistically significant correlation between confidence and competence for ECs (r = 0.60, p = 0.01), but not for PGTs. The change in this correlation was not statistically significant for either group, however.

DISCUSSION

Our findings suggest that ECs are not any more accurate in the assessment of their competence compared with PGTs. All procedural skills curricula can benefit from OSCE-format evaluation to better evaluate the improvement in performance of participants.

[The gynecological pessary: Is it really a device of another age, a fig leaf?]

OBJECTIVES

The use of pessary to put back up prolapsed organs to their normal position dates back prior to several millennia. This work aims to discuss its place in our clinical practice through an updated bibliographic review and emphasizes a hands-on approach to pessary fitting and management in terms of indication, pessary type selection, device' size, insertion, removal, follow-up visits and care.

METHODS

A review of the literature, in the light of the latest publications and recommendations of French and international learned societies, as well as our own experience, were analyzed.

RESULTS

This device appears to be as effective as surgical management to relieve symptoms related to urogenital prolapse and restore body image. It can be used temporarily, awaiting a surgical solution or as a therapeutic test (mimicking the effect of a surgical procedure to predict its functional outcome or identifying a masked urinary incontinence). It can also represent an alternative to surgery (patient choice, women who wish to complete childbearing or who are unsuitable for surgery because of medical comorbidities) and thus can be used in first intention. However, despite its moderate cost and its harmlessness, this device remains somewhat little known as regards the practical modalities of its use, which, moreover, appear not consensual.

CONCLUSION

A guide intended for the attention of the patients as well as a film relating to the practical modalities of the device' use were elaborated to improve the knowledge of both professionals and users in order to optimize and secure the care pathway.

Pessary use in stress urinary incontinence: a review of advantages, complications, patient satisfaction, and quality of life

Stress urinary incontinnce (SUI) is a common condition among women. The usual approach to treatment of SUI is a stepwise plan from conservative to surgical procedures. A vaginal pessary is one of the commonly used conservative treatments that offer symptomatic improvement for women with incontinence. This review provides a critical analysis of the benefits and shortcomings offered by vaginal pessaries to patients affected by SUI, with a particular focus on indications, advantages, quality of life, patient satisfaction, and potential complications. To obtain the required information, an extensive search of PubMed and Cochrane databases was performed, covering the time frame from January 2000 to December 2016. We also surveyed the published guidelines of American Urological Association, Canadian Urological Association, American Urogynecological Society, National Institutes of Health (USA), and National Institute for Health and Care Excellence (UK). A total of 192 original research papers, review articles, and clinical trials were identified. The analysis of retrieved data provides evidence that vaginal pessaries constitute an effective nonsurgical option for SUI. The satisfaction rate with pessary use is high and only minor complications, if any, occur, vaginal discharge being the most common. The reviewed studies document that vaginal pessaries provide an adequate control of SUI if they are fit properly and managed by frequent replacements and regular checkups. They should be considered among the first line of treatment for SUI associated with exercise and increased intra-abdominal pressure.

Original Flow Chart for the Management of Hydroureteronephrosis Caused by Pessary Placement

Hydroureteronephrosis due to pessary is a dangerous complication that can become critical if urosepsis is present. We propose a flow chart to manage the condition.

Introduction

The use of a pessary to treat a pelvic organ prolapse (POP) is a valid non-invasive option. Severe complications are usually associated with neglected, oversized, or misplaced pessaries. Major complications include fistulas, bowel or bladder erosion, and hydroureteronephrosis (HUN).

Materials and Methods

We reviewed the literature and our experience in the management of HUN in the last decade, as a consequence of pessary placement.

Results

We used flow charts to take an accurate medical history of each patient. Blood and urine analyses were taken at admission to assess the potential presence of sepsis, renal failure, and urinary tract infection. Physical examination included vaginal examination. In cases of pessary presence with a concomitant increase of serum creatinine value, a possible ureteral obstruction is suspected. In order to assess the presence of HUN and its underlying causes, a computed tomography (CT) scan should be performed to assess the mechanism of urinary tract obstruction. However, in case of renal insufficiency, abdominal ultrasonography (US) could be sufficient. If HUN is detected in a patient with no signs of urosepsis, we suggest a conservative management by the removal of the pessary and catheter placement. When urosepsis is suspected, it is mandatory to administer antibiotic therapy and evaluate the HUN drainage by nephrostomy.

Conclusions

There is no uniform management of women with HUN and a concomitant pessary. For this reason, and based on the literature and our experience, we propose an original management flowchart.

Pessary types and discontinuation rates in patients with advanced pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

The aim of this study was to investigate factors associated with long-term pessary use in patients with advanced pelvic organ prolapse (POP).

METHODS

This was a retrospective chart review of patients with POP of stage ≥2 managed with a pessary. Patients were excluded if the date of fitting or follow-up was unavailable. Long-term use was defined as more than 1 year. Patient demographics, pessary fitting, and follow-up visit dates were collected. The primary end point was the duration of use and the prognostic impact of pessary type. Secondary objectives addressed other influencing factors including age, estrogen use, and prolapse stage. The data were analyzed using SPSS version 21.

RESULTS

The final analysis included 311 patients. The mean (± standard deviation, SD) duration of pessary use was 7.0 ± 0.72 years (median 5.7 years). Long-term use was found in 76 % (164) of these patients. Factors associated with longer use were age >65 years (p = 0.004) and estrogen use (p = 0.048). The estimated mean (± SD) durations of use of the Gellhorn, open ring, ring with support, cube and donut pessaries were 10.5 ± 0.7 years, 3.4 ± 0.6 years, 1.8 ± 0.2 years, 1.8 ± 0.3 years and 1.7 ± 0.5 years, respectively. The Gellhorn pessary was associated with significantly longer use than other pessary types (10.5 ± 0.7, p < 0.0000001); this finding was independent of age, prolapse stage, hysterectomy, and vaginal estrogen use.

CONCLUSIONS

In this retrospective analysis, the duration of use was longest with the Gellhorn pessary. Older age and vaginal estrogen use were associated with longer pessary use.
