Review
BACKGROUND
Pelvic organ prolapse (POP) is the descent of a woman's uterus, bladder, or rectum into the vagina. It affects 50% of women over 50 years old who have given birth to at least one child, and recognised risk factors are older age, higher number of births, and higher body mass index. This review assesses the effects of oestrogen therapy, alone or in combination with other treatments, on POP in postmenopausal women.
OBJECTIVES
To assess the benefits and harms of local and systemic oestrogen therapy in the management of pelvic organ prolapse symptoms in postmenopausal women, and to summarise the principal findings of relevant economic evaluations.
SEARCH METHODS
We searched the Cochrane Incontinence Specialised Register (up to 20 June 2022), which includes CENTRAL, MEDLINE, two trials registers, and handsearching of journals and conference proceedings. We also checked the reference lists of relevant articles for additional studies.
SELECTION CRITERIA
We included randomised controlled trials (RCTs), quasi-RCTs, multi-arm RCTs, and cross-over RCTs that evaluated the effects of oestrogen therapy (alone or in combination with other treatments) versus placebo, no treatment, or other interventions in postmenopausal women with any grade of POP.
DATA COLLECTION AND ANALYSIS
Two review authors independently extracted data from the included trials using prespecified outcome measures and a piloted extraction form. The same review authors independently assessed the risk of bias of eligible trials using Cochrane's risk of bias tool. Had data allowed, we would have created summary of findings tables for our main outcome measures and assessed the certainty of the evidence using GRADE.
MAIN RESULTS
We identified 14 studies including a total of 1002 women. In general, studies were at high risk of bias in terms of blinding of participants and personnel, and there were also some concerns about selective reporting. Owing to insufficient data for the outcomes of interest, we were unable to perform our planned subgroup analyses (systemic versus topical oestrogen, parous versus nulliparous women, women with versus without a uterus). No studies assessed the effects of oestrogen therapy alone versus no treatment, placebo, pelvic floor muscle training, devices such as vaginal pessaries, or surgery. However, we did identify three studies that assessed oestrogen therapy in conjunction with vaginal pessaries versus vaginal pessaries alone and 11 studies that assessed oestrogen therapy in conjunction with surgery versus surgery alone.
AUTHORS' CONCLUSIONS
There was insufficient evidence from RCTs to draw any solid conclusions on the benefits or harms of oestrogen therapy for managing POP symptoms in postmenopausal women. Topical oestrogen in conjunction with pessaries was associated with fewer adverse vaginal events compared with pessaries alone, and topical oestrogen in conjunction with surgery was associated with reduced postoperative urinary tract infections compared with surgery alone; however, these findings should be interpreted with caution, as the studies that contributed data varied substantially in their design. There is a need for larger studies on the effectiveness and cost-effectiveness of oestrogen therapy, used alone or in conjunction with pelvic floor muscle training, vaginal pessaries, or surgery, for the management of POP. These studies should measure outcomes in the medium and long term.

Meta-Analysis Review
OBJECTIVE
The aim of our study is to systematically review the literature about available devices facilitating perineal support during defecation in patients with obstructive defecation syndrome (ODS) and posterior pelvic organ prolapse (POP).
METHODS
We searched for the terms "defecat/ion or ODS" and" pessar/ies or device/aid/tool/perineal/perianal/prolapse and support" in MEDLINE, PubMed and Web of Science. Data abstraction was performed according to PRISMA (Preferred Reporting Items for Systematic reviews and Meta-analysis) guidelines. A two-stage inclusion was performed, selecting first on title and abstract and secondly the full text. For variables with sufficient data, a meta-analysis was performed using a random-effects model. Other variables were descriptively reported.
RESULTS
Ten studies out of 1332 were included for systematic review. The devices could be categorized into three groups: pessaries (n = 8), vaginal stent (n = 1) and external support device (n = 1). Methodology and data reporting is heterogeneous. Meta-analysis could be performed for the Colorectal-Anal Distress Inventory (CRADI-8) and Impact Questionnaire (CRAI-Q-7) in three pessary studies which showed a significant mean change. Significant improvement of stool evacuation was seen in two other pessary studies. The vaginal stent significantly decreases ODS. Subjective perception of constipation improved significantly using the posterior perineal support device.
CONCLUSION
All reviewed devices seem to improve ODS in patients with POP. There are no data on their efficacy with regard to perineal descent-associated ODS. There is a lack of comparative studies between devices. Studies are difficult to compare due to different inclusion criteria and evaluation tools.

Review
BACKGROUND
Preterm birth is the leading cause of childhood mortality and morbidity. We aimed to provide a comprehensive systematic review on randomized controlled trials (RCTs) on progesterone, cerclage, pessary, and acetylsalicylic acid (ASA) to prevent preterm birth in asymptomatic women with singleton pregnancies defined as risk of preterm birth and multifetal pregnancies.
METHODS
Six databases (including PubMed, Embase, Medline, the Cochrane Library) were searched up to February 2022. RCTs published in English or Scandinavian languages were included through a consensus process. Abstracts and duplicates were excluded. The trials were critically appraised by pairs of reviewers. The Cochrane risk-of-bias tool was used for risk of bias assessment. Predefined outcomes including preterm birth, perinatal/neonatal/maternal mortality and morbidity, were pooled in meta-analyses using RevMan 5.4, stratified for high and low risk of bias trials. The certainty of evidence was assessed using the GRADE approach. The systematic review followed the PRISMA guideline.
RESULTS
The search identified 2,309 articles, of which 87 were included in the assessment: 71 original RCTs and 16 secondary publications with 23,886 women and 32,893 offspring. Conclusions were based solely on trials with low risk of bias ( = 50).Singleton pregnancies: Progesterone compared with placebo, reduced the risk of preterm birth <37 gestational weeks: 26.8% vs. 30.2% (Risk Ratio [RR] 0.82 [95% Confidence Interval [CI] 0.71 to 0.95]) (high certainty of evidence, 14 trials) thereby reducing neonatal mortality and respiratory distress syndrome. Cerclage probably reduced the risk of preterm birth <37 gestational weeks: 29.0% vs. 37.6% (RR 0.78 [95% CI 0.69 to 0.88]) (moderate certainty of evidence, four open trials). In addition, perinatal mortality may be reduced by cerclage. Pessary did not demonstrate any overall effect. ASA did not affect any outcome, but evidence was based on one underpowered study.Multifetal pregnancies: The effect of progesterone, cerclage, or pessary was minimal, if any. No study supported improved long-term outcome of the children.
CONCLUSION
Progesterone and probably also cerclage have a protective effect against preterm birth in asymptomatic women with a singleton pregnancy at risk of preterm birth. Further trials of ASA are needed. Prevention of preterm birth requires screening programs to identify women at risk of preterm birth.

Review
PURPOSE
Levator ani muscle (LAM) avulsion affects up to 35% of women. Unlike obstetric anal sphincter injury, LAM avulsion is not diagnosed immediately after vaginal delivery, however, has a profound impact on quality of life. The management of pelvic floor disorders is in growing demand yet the significance of LAM avulsion in the context of pelvic floor dysfunction (PFD) is poorly understood. This study collates information on success of treatment for LAM avulsion to establish the best options for management of women.
METHODS
MEDLINE, MEDLINE In-Process, EMBASE, PubMed, CINAHL and The Cochrane Library were searched for articles that evaluated the management techniques used to treat LAM avulsion. The protocol was registered with PROSPERO (CRD42021206427).
RESULTS
Natural healing of LAM avulsion occurs in 50% of women. Conservative measures, including pelvic floor exercises and pessary use are poorly studied. Pelvic floor muscle training for major LAM avulsions was of no benefit. Post-partum pessary use was only of benefit in the first three months for women. Surgeries for LAM avulsion are poorly researched but studies suggest they may provide benefit for 76-97% of patients.
CONCLUSIONS
Whilst some women with PFD secondary to LAM avulsion improve spontaneously, 50% continue to have pelvic floor symptoms 1 year following delivery. These symptoms result in a significant negative impact on quality of life, however, it is not clear whether conservative or surgical methods are helpful. There is a pressing need for research to find effective treatments and explore appropriate surgical repair techniques for women with LAM avulsion.

Review
Introduction: Quality of life (QoL) improvement is one of the main outcomes in the management of pelvic organ prolapse as a chronic illness in women. This systematic review aimed to investigate the impact of surgical or pessary treatment for pelvic organ prolapse (POP) on quality of life. Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was applied. Electronic databases, including PubMed, Scopus, and Web of Science, were searched for original articles that evaluated the QoL before and after surgical interventions or pessary in pelvic organ prolapse from 1 January 2012 until 30 June 2022 with a combination of proper keywords. Included studies were categorized based on interventions, and they were tabulated to summarize the results. Results: Overall, 587 citations were retrieved. Of these, 76 articles were found eligible for final review. Overall, three categories of intervention were identified: vaginal surgeries (47 studies), abdominal surgeries (18 studies), and pessary intervention (11 studies). Almost all interventions were associated with improved quality of life. The results of the meta-analysis showed a significant association between the employment of surgical approach techniques (including vaginal and abdominal surgeries) and the quality of life (Pelvic Floor Distress Inventory (PFDI) (MD: −48.08, 95% CI: −62.34 to −33.77, p-value < 0.01), Pelvic Floor Impact Questionnaire (PFIQ) (MD: −33.41, 95% CI: −43.48 to −23.34, p < 0.01)) and sexual activity of patients with pelvic organ prolapse (Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ) (MD: 4.84, 95% CI: 1.75 to 7.92, p < 0.01)). Furthermore, narrative synthesis for studies investigating the effect of the pessary approach showed a positive association between the use of this instrument and improvement in the quality of life and sexual activity. Conclusions: The results of our study revealed a significant improvement in the women’s quality of life following abdominal and vaginal reconstructive surgery. The use of pessary was also associated with increased patient quality of life.

Review
BACKGROUND
Preterm birth (PTB), defined as birth prior to 37 weeks of gestation, occurs in ten percent of all pregnancies. PTB is responsible for more than half of neonatal and infant mortalities and morbidities. Because cervical insufficiency is a common cause of PTB, one possible preventive strategy involves insertion of a cervical pessary to support the cervix. Several published studies have compared the use of pessary with different management options and obtained questionable results. This highlights the need for an up-to-date systematic review of the evidence.
OBJECTIVES
To evaluate the benefits and harms of cervical pessary for preventing preterm birth in women with singleton pregnancies and risk factors for cervical insufficiency compared to no treatment, vaginal progesterone, cervical cerclage or bedrest.
SEARCH METHODS
We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform to 22 September 2021. We also searched the reference lists of included studies for additional records.
SELECTION CRITERIA
We included published and unpublished randomised controlled trials (RCTs) comparing cervical pessary with no treatment, vaginal progesterone, cervical cerclage or bedrest for preventing PTB. We excluded quasi-randomised trials. Our primary outcome was delivery before 34 weeks' gestation. Our secondary outcomes were 1. delivery before 37 weeks' gestation, 2. maternal mortality, 3. maternal infection or inflammation, 4. preterm prelabour rupture of membranes, 5. harm to woman from the intervention, 6. maternal medications, 7. discontinuation of the intervention, 8. maternal satisfaction, 9. neonatal/paediatric care unit admission, 10. fetal/infant mortality, 11. neonatal sepsis, 12. gestational age at birth, 13. harm to offspring from the intervention 14. birthweight, 15. early neurodevelopmental morbidity, 15. late neurodevelopmental morbidity, 16. gastrointestinal morbidity and 17. respiratory morbidity.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trials for eligibility and risk of bias, evaluated trustworthiness based on criteria developed by the Cochrane Pregnancy and Childbirth Review Group, extracted data, checked for accuracy and assessed certainty of evidence using the GRADE approach.
MAIN RESULTS
We included eight RCTs (2983 participants). We included five RCTs (1830 women) in the comparison cervical pessary versus no treatment, three RCTs (1126 pregnant women) in the comparison cervical pessary versus vaginal progesterone, and one study (13 participants) in the comparison cervical pessary versus cervical cerclage. Overall, the certainty of evidence was low to moderate due to inconsistency (statistical heterogeneity), imprecision (few events and wide 95% confidence intervals (CIs) consistent with possible benefit and harm), and risk of performance and detection bias. Cervical pessary versus no treatment Cervical pessary compared with no treatment may reduce the risk of delivery before 34 weeks (risk ratio (RR) 0.72, 95% CI 0.33 to 1.55; 5 studies, 1830 women; low-certainty evidence) or before 37 weeks (RR 0.68, 95% CI 0.44 to 1.05; 5 studies, 1830 women; low-certainty evidence). However, these results should be viewed with caution because the 95% CIs cross the line of no effect. Cervical pessary compared with no treatment probably has little or no effect on the risk of maternal infection or inflammation (RR 1.04, 95% CI 0.87 to 1.26; 2 studies, 1032 women; moderate-certainty evidence). It is unclear if cervical pessary compared with no treatment has an effect on neonatal/paediatric care unit admission (RR 0.96, 95% CI 0.58 to 1.59; 3 studies, 1332 infants; low-certainty evidence) or fetal/neonatal mortality (RR 0.93, 95% CI 0.58 to 1.48; 5 studies, 1830 infants; low-certainty evidence) because the 95% CIs are compatible with a wide range of effects that encompass both appreciable benefit and harm. Cervical pessary versus vaginal progesterone Cervical pessary may reduce the risk of delivery before 34 weeks (RR 0.72, 95% CI 0.52 to 1.02; 3 studies, 1126 women; moderate-certainty evidence) or before 37 weeks (RR 0.89, 95% CI 0.73 to 1.09; 3 studies, 1126 women; moderate-certainty evidence), but we are uncertain of the results because the 95% CI crosses the line of no effect. The intervention probably has little or no effect on maternal infection or inflammation (RR 0.95, 95% CI 0.81 to 1.12; 2 studies, 265 women; moderate-certainty evidence). It is unclear if cervical pessary compared with vaginal progesterone has an effect on the risk of neonatal/paediatric care unit admission (RR 0.98, 95% CI 0.49 to 1.98; low-certainty evidence) or fetal/neonatal mortality (RR 1.97, 95% CI 0.50 to 7.70; 2 studies; 265 infants; low-certainty evidence) because the 95% CIs are compatible with a wide range of effects that encompass both appreciable benefit and harm. Cervical pessary versus cervical cerclage Only one very small study of 13 pregnant women contributed data to this comparison; the results were unclear.
AUTHORS' CONCLUSIONS
In women with a singleton pregnancy, cervical pessary compared with no treatment or vaginal progesterone may reduce the risk of delivery before 34 weeks or 37 weeks, although these results should be viewed with caution due to uncertainty around the effect estimates. There is insufficient evidence with regard to the effect of cervical pessary compared with cervical cerclage on PTB. Due to low certainty-evidence in many of the prespecified outcomes and non-reporting of several other outcomes of interest for this review, there is a need for further robust RCTs that use standardised terminology for maternal and offspring outcomes. Future trials should take place in a range of settings to improve generalisability of the evidence. Further research should concentrate on comparisons of cervical pessary versus cervical cerclage and bed rest. Investigation of different phenotypes of PTB may be relevant.

Review
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%, = 9/36), rectovaginal fistula (19%, = 7/36), vaginal impaction (11%, = 4/36) and vaginal evisceration of small bowel through vaginal vault (8%, = 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.

Meta-Analysis
OBJECTIVE
To investigate the risk of preterm birth in women with a placenta previa or a low-lying placenta for different cut-offs of gestational age and to evaluate preventive interventions.
SEARCH AND METHODS
MEDLINE, EMBASE, CENTRAL, Web of Science, WHO-ICTRP and clinicaltrials.gov were searched until December 2021. Randomized controlled trials, cohort studies and case-control studies assessing preterm birth in women with placenta previa or low-lying placenta with a placental edge within 2 cm of the internal os in the second or third trimester were eligible for inclusion. Pooled proportions and odds ratios for the risk of preterm birth before 37, 34, 32 and 28 weeks of gestation were calculated. Additionally, the results of the evaluation of preventive interventions for preterm birth in these women are described.
RESULTS
In total, 34 studies were included, 24 reporting on preterm birth and 9 on preventive interventions. The pooled proportions were 46% (95% CI [39 - 53%]), 17% (95% CI [11 - 25%]), 10% (95% CI [7 - 13%]) and 2% (95% CI [1 - 3%]), regarding preterm birth <37, <34, <32 and <28 weeks in women with placenta previa. For low-lying placentas the risk of preterm birth was 30% (95% CI [19 - 43%]) and 1% (95% CI [0 - 6%]) before 37 and 34 weeks, respectively. Women with a placenta previa were more likely to have a preterm birth compared to women with a low-lying placenta or women without a placenta previa for all gestational ages. The studies about preventive interventions all showed potential prolongation of pregnancy with the use of intramuscular progesterone, intramuscular progesterone + cerclage or pessary.
CONCLUSIONS
Both women with a placenta previa and a low-lying placenta have an increased risk of preterm birth. This increased risk is consistent across all severities of preterm birth between 28-37 weeks of gestation. Women with placenta previa have a higher risk of preterm birth than women with a low-lying placenta have. Cervical cerclage, pessary and intramuscular progesterone all might have benefit for both women with placenta previa and low-lying placenta, but data in this population are lacking and inconsistent, so that solid conclusions about their effectiveness cannot be drawn.

Meta-Analysis
OBJECTIVE
To evaluate the existing evidence on the efficacy of pessaries in improving quality of life when used for the treatment of pelvic organ prolapse (POP).
DATA SOURCES
We searched for the terms "pelvic organ prolapse" and "pessar/y/ies/ium or vaginal support device," and "safety or safe or outcome or complication or efficacy or effective or effectiveness" in PubMed, EMBASE, and CINAHL on March 16, 2020. A search was also performed on ClinicalTrials.gov , with no studies fitting our strict inclusion and exclusion criteria.
METHODS OF STUDY SELECTION
Studies that reported pretreatment and posttreatment mean scores and SDs after pessary treatment for standardized questionnaires were included. Studies performed in pediatric populations, pregnancy, and use of pessaries not for prolapse were excluded. Three reviewers independently screened studies.
TABULATION, INTEGRATION, AND RESULTS
Data abstraction was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Data were pooled for meta-analysis when reported by at least three studies. The primary study outcome was change in mean pretreatment and posttreatment questionnaire scores, which included those for the PFDI-20 (Pelvic Floor Distress Inventory- Short Form 20), PFIQ-7 (Pelvic Floor Impact Questionnaire - Short Form 7), and subscale POPIQ (Pelvic Organ Prolapse Impact Questionnaire Long Form). A random-effects model was used to combine estimates and capture between-study heterogeneity using the I 2 -statistic. Eight studies including 627 patients were included for systematic review. The mean (SD) age was 63.0±12.2 years, and the majority of patients had stage III prolapse (48.1%) followed by stage II prolapse (43.2%) when reported. Although variable, the majority of studies conducted 3-month follow-up. A negative change in pretreatment and posttreatment scores was noted, signifying improvement after pessary use: PFDI-20 mean change -46.1 (95% CI -65.4 to -26.8); PFIQ-7 mean change -36.0 (95% CI -46.0 to -26.0); POPIQ-7 (Pelvic Organ Prolapse Impact Questionnaire-7) mean change -16.3 (95% CI -26.8 to -5.7). No significant heterogeneity was found.
CONCLUSION
Based on improvements in standardized questionnaire scores, pessaries are effective treatment options for POP.

Review
BACKGROUND
Urinary incontinence (UI) is the involuntary loss of urine and can be caused by several different conditions. The common types of UI are stress (SUI), urgency (UUI) and mixed (MUI). A wide range of interventions can be delivered to reduce the symptoms of UI in women. Conservative interventions are generally recommended as the first line of treatment.
OBJECTIVES
To summarise Cochrane Reviews that assessed the effects of conservative interventions for treating UI in women.
METHODS
We searched the Cochrane Library to January 2021 (CDSR; 2021, Issue 1) and included any Cochrane Review that included studies with women aged 18 years or older with a clinical diagnosis of SUI, UUI or MUI, and investigating a conservative intervention aimed at improving or curing UI. We included reviews that compared a conservative intervention with 'control' (which included placebo, no treatment or usual care), another conservative intervention or another active, but non-conservative, intervention. A stakeholder group informed the selection and synthesis of evidence. Two overview authors independently applied the inclusion criteria, extracted data and judged review quality, resolving disagreements through discussion. Primary outcomes of interest were patient-reported cure or improvement and condition-specific quality of life. We judged the risk of bias in included reviews using the ROBIS tool. We judged the certainty of evidence within the reviews based on the GRADE approach. Evidence relating to SUI, UUI or all types of UI combined (AUI) were synthesised separately. The AUI group included evidence relating to participants with MUI, as well as from studies that combined women with different diagnoses (i.e. SUI, UUI and MUI) and studies in which the type of UI was unclear.
MAIN RESULTS
We included 29 relevant Cochrane Reviews. Seven focused on physical therapies; five on education, behavioural and lifestyle advice; one on mechanical devices; one on acupuncture and one on yoga. Fourteen focused on non-conservative interventions but had a comparison with a conservative intervention. No reviews synthesised evidence relating to psychological therapies. There were 112 unique trials (including 8975 women) that had primary outcome data included in at least one analysis. Stress urinary incontinence (14 reviews) Conservative intervention versus control: there was moderate or high certainty evidence that pelvic floor muscle training (PFMT), PFMT plus biofeedback and cones were more beneficial than control for curing or improving UI. PFMT and intravaginal devices improved quality of life compared to control. One conservative intervention versus another conservative intervention: for cure and improvement of UI, there was moderate or high certainty evidence that: continence pessary plus PFMT was more beneficial than continence pessary alone; PFMT plus educational intervention was more beneficial than cones; more-intensive PFMT was more beneficial than less-intensive PFMT; and PFMT plus an adherence strategy was more beneficial than PFMT alone. There was no moderate or high certainty evidence for quality of life. Urgency urinary incontinence (five reviews) Conservative intervention versus control: there was moderate to high-certainty evidence demonstrating that PFMT plus feedback, PFMT plus biofeedback, electrical stimulation and bladder training were more beneficial than control for curing or improving UI. Women using electrical stimulation plus PFMT had higher quality of life than women in the control group. One conservative intervention versus another conservative intervention: for cure or improvement, there was moderate certainty evidence that electrical stimulation was more effective than laseropuncture. There was high or moderate certainty evidence that PFMT resulted in higher quality of life than electrical stimulation and electrical stimulation plus PFMT resulted in better cure or improvement and higher quality of life than PFMT alone. All types of urinary incontinence (13 reviews) Conservative intervention versus control: there was moderate to high certainty evidence of better cure or improvement with PFMT, electrical stimulation, weight loss and cones compared to control. There was moderate certainty evidence of improved quality of life with PFMT compared to control. One conservative intervention versus another conservative intervention: there was moderate or high certainty evidence of better cure or improvement for PFMT with bladder training than bladder training alone. Likewise, PFMT with more individual health professional supervision was more effective than less contact/supervision and more-intensive PFMT was more beneficial than less-intensive PFMT. There was moderate certainty evidence that PFMT plus bladder training resulted in higher quality of life than bladder training alone.
AUTHORS' CONCLUSIONS
There is high certainty that PFMT is more beneficial than control for all types of UI for outcomes of cure or improvement and quality of life. We are moderately certain that, if PFMT is more intense, more frequent, with individual supervision, with/without combined with behavioural interventions with/without an adherence strategy, effectiveness is improved. We are highly certain that, for cure or improvement, cones are more beneficial than control (but not PFMT) for women with SUI, electrical stimulation is beneficial for women with UUI, and weight loss results in more cure and improvement than control for women with AUI. Most evidence within the included Cochrane Reviews is of low certainty. It is important that future new and updated Cochrane Reviews develop questions that are more clinically useful, avoid multiple overlapping reviews and consult women with UI to further identify outcomes of importance.
