Pelvic floor injury during vaginal birth is life-altering and preventable: what can we do about it?

Pelvic floor disorders after childbirth have distressing lifelong consequences for women, requiring more than 300,000 women to have surgery annually. This represents approximately 10% of the 3 million women who give birth vaginally each year. Vaginal birth is the largest modifiable risk factor for prolapse, the pelvic floor disorder most strongly associated with birth, and is an important contributor to stress incontinence. These disorders require 10 times as many operations as anal sphincter injuries. Imaging shows that injuries of the levator ani muscle, perineal body, and membrane occur in up to 19% of primiparous women. During birth, the levator muscle and birth canal tissues must stretch to more than 3 times their original length; it is this overstretching that is responsible for the muscle tear visible on imaging rather than compression or neuropathy. The injury is present in 55% of women with prolapse later in life, with an odds ratio of 7.3, compared with women with normal support. In addition, levator damage can affect other aspects of hiatal closure, such as the perineal body and membrane. These injuries are associated with an enlarged urogenital hiatus, now known as antedate prolapse, and with prolapse surgery failure. Risk factors for levator injury are multifactorial and include forceps delivery, occiput posterior birth, older maternal age, long second stage of labor, and birthweight of >4000 g. Delivery with a vacuum device is associated with reduced levator damage. Other steps that might logically reduce injuries include manual rotation from occiput posterior to occiput anterior, slow gradual delivery, perineal massage or compresses, and early induction of labor, but these require study to document protection. In addition, teaching women to avoid pushing against a contracted levator muscle would likely decrease injury risk by decreasing tension on the vulnerable muscle origin. Providing care for women who have experienced difficult deliveries can be enhanced with early recognition, physical therapy, and attention to recovery. It is only right that women be made aware of these risks during pregnancy. Educating women on the long-term pelvic floor sequelae of childbirth should be performed antenatally so that they can be empowered to make informed decisions about management decisions during labor.

Pelvic floor dysfunction after intervention, compared with expectant management, in prolonged second stage of labour: A population-based questionnaire and cohort study.

OBJECTIVE: To investigate the effect of vacuum extraction (VE) or caesarean section (CS), compared with expectant management, on pelvic floor dysfunction (PFD) 1-2 years postpartum in primiparous women with a prolonged second stage of labour. DESIGN: A population-based questionnaire and cohort study. SETTING: Stockholm, Sweden. POPULATION: A cohort of 1302 primiparous women with a second stage duration of ≥3 h, delivering from December 2017 to November 2018. METHODS: The 1-year follow-up questionnaire from the Swedish National Perineal Laceration Register was distributed 12-24 months postpartum. Exposure was VE or CS at 3-4 h or 4-5 h, compared with expectant management. MAIN OUTCOME MEASURES: Pelvic floor dysfunction was defined as at least weekly symptoms of urinary incontinence, pelvic organ prolapse or a Wexner score of ≥4. The risk of PFD was calculated using Poisson regression with robust variance estimation, presented as crude and adjusted relative risks (RRs and aRRs) with 95% confidence intervals (95% CIs). The implication of obstetric anal sphincter injury (OASI) on pelvic floor disorders was investigated through mediation analysis. RESULTS: In total, 35.1% of women reported PFD. Compared with expectant management, the risk of PFD was increased after VE at 3-4 h (aRR 1.33, 95% CI 1.06-1.65) and 4-5 h (aRR 1.34, 95% CI 1.05-1.70), but remained unchanged after CS. The increased risk after VE was not mediated by OASI. CONCLUSIONS: Pelvic floor dysfunction was common in primiparous women after a prolonged second stage, and the risk of PFD increased after VE but was unaffected by CS, compared with expectant management. If a spontaneous vaginal delivery eventually occurred, allowing an extended duration of labour did not increase the risk of PFD.

Epidemiology of Pelvic Floor Dysfunction in the Tacna Region of Peru, 2023.

INTRODUCTION AND HYPOTHESIS: Urinary incontinence (UI) is highly prevalent in the general population, with numerous studies conducted in Europe and North America. However, there is a scarcity of data regarding its prevalence and sociodemographic factors in the southern region of Peru. There is an association between sociodemographic factors-such as age, educational level, body mass index, number of pregnancies, parity, mode of delivery, weight of the newborn-along with lifestyle factors such as physical effort, coffee and tobacco consumption with pelvic floor dysfunction (PFD). We anticipate that this association will negatively impact women's quality of life. METHODS: This was a quantitative study, with a non-experimental, descriptive, cross-sectional correlational design. A sample consisting of 468 women between 30 and 64 years old. A previously tested survey was applied to explore prevalence, symptoms, associated factors, and quality of life. RESULTS: The prevalence of PFD was 73.9%. UI was the most common. There is a significant association with overweight, obesity, parity, route of delivery, and physical effort. Even though a large percentage of participants presented with PFD, they reported that their quality of life was not affected (65.9% urinary discomfort, 96.5% colorectal-anal discomfort and 92.2% pelvic organ prolapse discomfort) and only in the case of urinary discomfort did they state that the impact was mild (28.6%) and moderate (5.5%). CONCLUSIONS: Pelvic floor dysfunction in women is very common and it is strongly associated with overweight, obesity, parity, route of delivery, and physical exertion. The impact on quality of life was mild and moderate for those who had urinary discomfort.

Comparison of Cross-Sectional Area of Pubovisceral Muscle in Nulliparous and Primiparous Women.

INTRODUCTION AND HYPOTHESIS: The main risk factor for pelvic floor disorders is vaginal delivery, which may cause levator ani muscle (LAM) injury and denervation. LAM includes pubovisceral muscle (PVM, pubococcygeus), puborectalis muscle (PRM), and iliococcygeus muscle. We hypothesize that primiparous women with low pelvic floor muscle contraction have a reduced PVM cross-sectional area (CSA) compared to nulliparous women. METHODS (SAMPLE SIZE AND STATISTICAL APPROACHES): This single-centre prospective observational study compared healthy nulliparous (n = 40) to primiparous (n = 40) women after vaginal delivery without LAM avulsion and Oxford score ≤ 3. Demographics, questionnaires (ICIQ-UI-SF, OAB-Q-SF, PISQ-12), POP-Q, Oxford score, ultrasound measurements (minimal anteroposterior and lateral diameters, hiatal area, PRM thickness, levator-urethra gap) and magnetic resonance imaging (MRI)-PVM CSA were evaluated. Normality was tested, and an appropriate test was used to compare the groups. Power calculation suggested 40 participants per group. RESULTS: The primiparous group was older, had a higher BMI, and their hiatal area on ultrasound at contraction was larger compared to the nulliparous group. The CSA of the left-sided PVM (1.15 ± 0.50 cm2) was larger compared to the right side (1.03 ± 0.50 cm2), p = 0.02 in nulliparous women. The PVM CSA of primiparous women with low Oxford score was reduced compared to nulliparous (0.87 ± 0.30 versus 1.09 ± 0.50 cm2, p = 0.006). The intra-rater reliability for PVM CSA had an ICC of 0.90 and inter-rater ICC of 0.77. CONCLUSIONS: Primiparous women after vaginal delivery with low pelvic floor contraction force had reduced PVM CSA on MRI images compared to nulliparous women.

Systematic Review and Meta-analysis of the Prevalence of Levator Ani Avulsion with Obstetric Anal Sphincter Injury and its Effects on Pelvic Floor Dysfunction.

INTRODUCTION AND HYPOTHESIS: The objective was to evaluate the prevalence of levator ani avulsion (LAA) among primiparous women with obstetric anal sphincter injury (OASI) and how this association could affect future pelvic floor dysfunction. METHODS: Three electronic databases (MEDLINE/PubMed/EMBASE) were searched in December 2018 and again in October 2022. Nine full-text articles were included in the analysis. The exclusion criteria were language other than English, studies not based on primiparous women only, conference abstracts, and evaluation without ultrasound or MRI. RESULTS: The overall prevalence of LAA was 24% (95% CI: 18-30%). Those with OASI, were at a higher risk of LAA, OR 3.49 (95% CI: 1.46 to 8.35). In women with LAA + OASI versus OASI alone, Three of Five studies showed worsened AI symptoms. Three of Five studies assessing urinary incontinence (UI) reported no significant difference in UI, whereas two reported increased UI. All studies that looked at pelvic organ prolapse reported a higher incidence of symptomatic prolapse and reduced pelvic floor muscle strength in women with LAA + OASI compared with those without LAA. CONCLUSION: Levator ani avulsion is prevalent following vaginal birth and is strongly associated with OASI. Incidence of AI does not increase in women with LAA and OASI, but they had greater symptom bother. OASI with LAA appears to increase the incidence of pelvic floor weakness and pelvic organ prolapse. There is no consensus agreement on the effect of LAA + OASI on UI.

Pelvic floor symptoms according to the severity of second-degree perineal tears within 12 months post-partum: A longitudinal prospective cohort study.

INTRODUCTION: Second-degree perineal tears following vaginal birth are common and presumed to be of little clinical importance. However, the extent of damage to the perineal body varies widely, and there is reason to believe that larger second-degree tears may be associated with more pelvic floor symptoms, compared to lesser form. Therefore, the aim of this study was to assess differences in pelvic floor symptoms according to the severity of second-degree perineal tears up to 12 months post-partum, stratified by parity. MATERIAL AND METHODS: This was a prospective cohort study conducted at Akershus University Hospital, a tertiary referral hospital in Norway. The study sample consisted of 409 primiparas and 394 multiparas with vaginal births. Perineal tears were classified using the classification system recommended by the Royal College of Obstetricians and Gynecologists. Further, second-degree tears were subclassified as 2A, 2B, or 2C, depending on the percentage of damage to the perineal body. Episiotomies were analyzed as a separate group. Pelvic floor symptoms were assessed using the Karolinska Symptoms After Perineal Tear Inventory (KAPTAIN). A linear mixed model was estimated to assess the trend in pelvic floor symptom scores according to perineal tear category and stratified by parity. The primary and secondary outcome measures were the mean sum scores of the KAPTAIN-Inventory, measured in pregnancy (at 18 weeks of gestation), at 3- and 12 months post-partum, and the reported impact of genital discomfort on quality of life measured in pregnancy and at 12 months post-partum. RESULTS: There were no significant differences in pelvic floor symptom scores over time, or at any timepoint, between no tear, first-degree tear, or second-degree tear subcategories, for primi-, and multiparas. Pelvic floor symptoms increased from pregnancy to 3 months post-partum and remained higher at 12 months post-partum compared to pregnancy in all perineal tear categories. Compared to primiparas, multiparas reported a significantly higher impact of genital discomfort on quality of life in pregnancy and at 12 months post-partum. CONCLUSIONS: There were no statistically significant differences in pelvic floor symptoms according to the severity of second-degree perineal tears.

Pelvic floor disorders among amateur runners.

BACKGROUND: Sports and physical activity are known risk factors for pelvic floor dysfunction (PFD). The aim of this study is to examine the impact of amateur running on PFD, quality of life (QoL), and sexual function. METHODS: Amateur runners were contacted through social media. Their PFD, sexual function, and QoL were evaluated by self-reporting validated questionnaires (PFDI-20, PISQ-12, IIQ-7). They were divided by degree of effort into two categories, 'High effort' and 'Moderate effort'. The differences between the two groups were examined by a Mann-Whitney U Test, T-Test, and Chi-square test. RESULTS: 180 women were included. A high incidence of PFD was found among 'High effort' runners in comparison to 'Moderate effort' runners. In addition, women who scored above the median in the PFDI-20 showed significantly greater impairment in QoL and sexual function. Interestingly, the 'High effort' group reported experiencing higher intensity orgasms compared with women in the 'Moderate effort' group. A correlation was also found between the weekly running distance and the intensity of orgasm experienced (P value = 0.004). CONCLUSION: 'High effort' runners present a higher incidence of PFD in comparison to 'Moderate effort' runners. Professional pelvic floor muscle training counselling should be considered even for amateur runners. Future interventional physical therapy studies should be carried out in order to investigate preventative strategies.

Early adulthood and current physical activity and their association with symptoms of pelvic floor disorders in middle-aged women: An observational study with retrospective physical activity assessment.

OBJECTIVE: To investigate associations of early and middle adulthood physical activity (PA) with symptoms of pelvic floor disorders (PFDs), i.e. stress urinary incontinence (SUI), urge urinary incontinence (UUI), faecal incontinence (FI), constipation or defecation difficulties (CDDs) and feeling of pelvic organ prolapse (POP) among middle-aged women. DESIGN: A cross-sectional, observational study with retrospective PA assessment. SETTING: University Research Laboratory. SAMPLE: A random population sample of 1098 Finnish women aged 47-55 years. METHODS: Early adulthood PA, current PA, and demographic and gynaecological variables were assessed using self-report questionnaires. Logistic regression analyses were applied to study associations of PA variables with symptoms of PFDs. Potential confounding effects of demographic and gynaecological variables were controlled in multiple logistic regression models. MAIN OUTCOME MEASURES: Structured questionnaire-assessed retrospective PA assessment at the age of 17-29 years, current PA at middle age, and prevalence of symptoms of CDD, FI, POP, SUI and UUI. RESULTS: Current PA was not independently associated with the occurrence of the symptoms of PFDs. Middle-aged women with an early adulthood history of competitive sports were more likely to experience symptoms of UUI (OR 2.16, 95% CI 1.10-4.24, p = 0.025) but not symptoms of SUI, FI, CDD or POP, whereas women with a history of regular PA were more likely to experience symptoms of FI (OR 4.41, 95% CI 1.05-18.49, p = 0.043) but no other symptoms of PFDs. CONCLUSIONS: Competitive sports during early adulthood may increase the risk of UUI in middle age. Regular PA during early adulthood may increase the risk of FI.

Postpartum pelvic floor muscle training, levator ani avulsion and levator hiatus area: a randomized trial.

INTRODUCTION AND HYPOTHESIS: Vaginal delivery may lead to tearing of the levator ani (LA) muscle from its bony insertions (complete LA avulsion) and increased levator hiatus (LH) area, both risk factors for pelvic floor dysfunctions. Early active rehabilitation is standard treatment after musculo-skeletal injury. We hypothesized that pelvic floor muscle training (PFMT) early postpartum would reduce the presence of LA avulsions and reduce LH area. METHODS: We carried out a planned secondary analysis from a randomized controlled study. Primiparous women (n=175) giving birth vaginally were included 6 weeks postpartum, stratified on complete LA avulsion, and thereafter randomized to PFMT or control. The training participants (n=87) attended a supervised PFMT class once a week and performed home-based PFMT daily for 16 weeks. The control participants (n=88) received no intervention. Presence of complete LA avulsion, LH area at rest, maximal contraction, and maximal Valsalva maneuver were assessed by transperineal ultrasound. Between-group comparisons were analyzed by analysis of covariance for continuous data, and relative risk (RR) for categorical data. RESULTS: Six months postpartum, the number of women who had complete LA avulsion was reduced from 27 to 14 within the PFMT group (44% reduction) and from 28 to 17 within the control group (39% reduction). The between-group difference was not significant, RR 0.85 (95% CI 0.53 to 1.37). Further, no significant between-group differences were found for LH area at rest, during contraction, or Valsalva. CONCLUSIONS: Supervised PFMT class combined with home exercise early postpartum did not reduce the presence of complete LA avulsion or LH area more than natural remission.

A pilot study to evaluate changes in pelvic floor muscle tone following pelvic organ prolapse surgery using a novel intra-vaginal pressure sensor device.

INTRODUCTION AND HYPOTHESIS: Pelvic floor muscle weakness is a common cause of pelvic organ prolapse and urinary incontinence. Surgical repair of prolapse is commonly undertaken; however, the impact on pelvic floor muscle tone is unknown. The aim of this study was to compare the effect of anterior and posterior colporrhaphy on pelvic floor activation. METHODS: Patients aged under 70 undergoing primary anterior or posterior colporrhaphy were recruited. Intra-vaginal pressure was measured at rest and during pelvic floor contraction using the Femfit® device (an intra-vaginal pressure sensor device [IVPSD]). Peak pressure and mean pressure over 3 s were measured in millimetres of mercury. The pre- and post-operative measurements were compared. The difference between the means was assessed using Cohen's D test, with significance set at p<0.05 RESULTS: A total of 37 patients completed pre- and post-operative analysis, 25 in the anterior colporrhaphy group and 12 in the posterior colporrhaphy group. Anterior colporrhaphy showed no significant change in pelvic floor tone. Change in peak pressure was -1.71mmHg (-5.75 to 2.33; p=0.16) and change in mean pressure was -0.86 mmHg (-4.38 to 2.66; p=0.31). Posterior colporrhaphy showed a significant increase in peak pelvic floor muscle tone of 7.2 mmHg (0.82 to 13.58; p=0.005) and mean pressure of 4.19 mmHg (-0.09 to 8.47; p=0.016). CONCLUSIONS: Posterior colporrhaphy significantly improves pelvic floor muscle tone, whereas anterior colporrhaphy does not. Improved understanding of the impact of pelvic floor surgery may guide future management options for other pelvic floor disorders. Further work is needed to confirm the association of this improvement in pelvic floor disorders.

Pelvic floor dysfunctions in women with systemic lupus erythematosus: A cross-sectional study.

INTRODUCTION AND HYPOTHESIS: As a result of the impairment of the musculoskeletal system, the pelvic floor muscles are likely compromised in women with systemic lupus erythematosus (SLE). We hypothesized that women with SLE would report more symptoms of pelvic floor dysfunction (PFD) and there will be an association between SLE and PFD. METHODS: An online cross-sectional survey was conducted. Data were collected on demographic and anthropometric characteristics, PFD (urinary incontinence, nocturia, anal incontinence, genital-pelvic pain/penetration disorder and pelvic organ prolapse) and obstetric history using a web-based questionnaire. The groups were compared using the Mann-Whitney test for quantitative variables and the chi-squared test for categorical variables. The association between SLE and PFD was tested using logistic regression analysis. RESULTS: A total of 196 women answered the questionnaire (102 with SLE and 94 healthy controls). Women with SLE reported significantly more urinary incontinence, nocturia, anal incontinence, pelvic organ prolapse and genital-pelvic pain/penetration disorder than the healthy controls (p ≤ 0.05). Women with SLE were 2.8- to 3.0-fold more likely to report genital-pelvic pain/penetration disorder than healthy women. CONCLUSIONS: The prevalence of PFD was significantly higher in women with SLE compared to healthy women. Thus, PFD seems to be an important problem in women with this disease. An in-depth investigation of these disorders could contribute to the understanding of how SLE impacts pelvic floor function.

Characteristics Associated with Pelvic Floor Disorders among Female Canadian Armed Forces Members.

OBJECTIVES: Urinary incontinence (UI) and pelvic organ prolapse (POP) are prevalent pelvic floor disorders (PFDs) among the female population. In the military environment, being a non-commissioned member (NCM), and physically demanding occupations are factors associated with higher PFD risk. This study seeks to characterize the profile of female Canadian Armed Forces (CAF) members reporting symptoms of UI and/or POP. METHODS: Present CAF members (18-65 years) responded to an online survey. Only current members were included in the analysis. Symptoms of UI and POP were collected. Multivariate logistic regressions analyzed the relationships between PFD symptoms and associated characteristics. RESULTS: 765 active members responded to female-specific questions. The prevalence of self-reported POP and UI symptoms were 14.5% and 57.0%, respectively, with 10.6% of respondents reporting both. Advanced age (adjusted odds ratio [aOR]: 1.062, CI 1.038-1.087), a body mass index (BMI) categorized as obese (aOR: 1.909, [1.183-3.081]), parity ≥1 (e.g., aOR for 1: 2.420, [1.352-4.334]) and NCMs (aOR: 1.662, [1.144-2.414]) were factors associated with urine leakage. Parity of ≥2 (aOR: 2.351, [1.370-4.037]) compared to nulliparous and having a perception of a physically demanding job (aOR: 1.933, [1.186-3.148]) were associated with experiencing POP symptoms. Parity of ≥2 increased the odds of reporting both PFD symptoms (aOR: 5.709, [2.650-12.297]). CONCLUSION: Parity was associated with greater odds of experiencing symptoms of UI and POP. Higher age, higher BMI, and being an NCM were associated with more symptoms of UI, and the perception of having a physically demanding role increased the likelihood of reporting POP symptoms.

PFD-SENTINEL: Development of a screening tool for pelvic floor dysfunction in female athletes through an international Delphi consensus.

To develop a screening tool for pelvic floor dysfunction (PFD) in female athletes for use by sports medicine clinicians (eg, musculoskeletal/sports physiotherapists, sports and exercise medicine physicians), which guides referral to a PFD specialist (eg, pelvic floor/women's health physiotherapist, gynaecologist, urogynaecologist, urologist).Between February and April 2022, an international two-round modified Delphi study was conducted to assess expert opinion on which symptoms, risk factors and clinical and sports-related characteristics (items) should be included in a screening tool. We defined consensus a priori as >67% response agreement to pass each round.41 and 34 experts participated in rounds 1 and 2, respectively. Overall, seven general statements were endorsed as relevant by most participants highlighting the importance of screening for PFD in female athletes. Through consensus, the panel developed the Pelvic Floor Dysfunction-ScrEeNing Tool IN fEmale athLetes (PFD-SENTINEL) and agreed to a cluster of PFD symptoms (n=5) and items (risk factors, clinical and sports-related characteristics; n=28) that should prompt specialist care. A clinical algorithm was also created: a direct referral is recommended when at least one symptom or 14 items are reported. If these thresholds are not reached, continuous monitoring of the athlete's health is indicated.Despite increasing awareness and clinical relevance, barriers to identify PFD in female athletes are still present. The PFD-SENTINEL is a new resource for sports medicine clinicians who regularly assess female athletes and represents the first step towards early PFD identification and management. Further studies to validate the tool are needed.

Management of levator ani avulsion: a systematic review and narrative synthesis.

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.

Levator ani avulsion: a Systematic evidence review (LASER).

BACKGROUND: There is variation in the reported incidence rates of levator avulsion (LA) and paucity of research into its risk factors. OBJECTIVE: To explore the incidence rate of LA by mode of birth, imaging modality, timing of diagnosis and laterality of avulsion. SEARCH STRATEGY: We searched MEDLINE, EMBASE, CINAHL, AMED and MIDIRS with no language restriction from inception to April 2019. STUDY ELIGIBILITY CRITERIA: A study was included if LA was assessed by an imaging modality after the first vaginal birth or caesarean section. Case series and reports were not included. DATA COLLECTION AND ANALYSIS: RevMan v5.3 was used for the meta-analyses and SW SAS and STATISTICA packages were used for type and timing of imaging analyses. RESULTS: We included 37 primary non-randomised studies from 17 countries and involving 5594 women. Incidence rates of LA were 1, 15, 21, 38.5 and 52% following caesarean, spontaneous, vacuum, spatula and forceps births, respectively, with no differences by imaging modality. Odds ratio of LA following spontaneous birth versus caesarean section was 10.69. The odds ratios for LA following vacuum and forceps compared with spontaneous birth were 1.66 and 6.32, respectively. LA was more likely to occur unilaterally than bilaterally following spontaneous (P < 0.0001) and vacuum-assisted (P = 0.0103) births but not forceps. Incidence was higher if assessment was performed in the first 4 weeks postpartum. CONCLUSIONS: LA incidence rates following caesarean, spontaneous, vacuum and forceps deliveries were 1, 15, 21 and 52%, respectively. Ultrasound and magnetic resonance imaging were comparable tools for LA diagnosis. TWEETABLE ABSTRACT: Levator avulsion incidence rates after caesarean, spontaneous, vacuum and forceps deliveries were 1, 15, 21 and 52%, respectively.

Surface electromyography of the pelvic floor at 6-8 weeks following delivery: a comparison of different modes of delivery.

INTRODUCTION AND HYPOTHESIS: The objective of this study was to compare the impact of different modes of delivery, especially forceps delivery (FD), on pelvic floor muscles (PFMs) through vaginal surface electromyography (sEMG) in primiparous women at early (6-8 weeks) postpartum. METHODS: A total of 1259 primiparous women with full-term singleton births were included in this cross-sectional study. Of these, 98 were delivered by forceps, 865 underwent spontaneous vaginal delivery (SD) and 296 underwent elective cesarean delivery (CD). Clinical demographic characteristics and vaginal sEMG variables of parturients 6-8 weeks after birth were collected and analyzed using SPSS software. One-way ANOVA with Bonferroni correction, Chi-square test or Student's t-test was used according to the variable type. Spearman correlation and binary logistic regression analyses were also used. P/α ≤ 0.05 was considered statistically significant. RESULTS: Amplitude of fast and sustained contractions on sEMG in the FD group was significantly lower compared with the CD and SD groups. The sEMG amplitude of all contractions was significantly higher in the CD group compared with the FD and SD groups (P < 0.01). According to binary logistic regression analysis, mode of delivery was a major influencing factor in sEMG. CONCLUSIONS: An early postpartum sEMG test appears to be helpful for the assessment of PFM activity. Mode of delivery was a major influencing factor on sEMG. Forceps delivery significantly inversely influenced PFM activity.

Association between striae gravidarum and pelvic floor dysfunction symptoms during pregnancy.

INTRODUCTION AND HYPOTHESIS: Striae gravidarum are linear atrophic scars appearing on the abdomen of pregnant women reported to be related to pregnancy-induced changes in the connective tissue. Pelvic floor distress symptoms are also known to be linked to connective tissue weakness. Given that common pathophysiological pathways may play a role in both striae gravidarum and pelvic floor dysfunction symptoms, we sought to examine whether there is a correlation between them during pregnancy. METHODS: A prospective observational study among third-trimester pregnant women who visited a tertiary medical center for routine pregnancy follow-up was conducted by using the Pelvic Floor Distress Inventory (PFDI-20) questionnaire to evaluate pelvic floor distress symptoms and the Davey method for evaluating striae gravidarum severity. Obstetrical characteristics as well as pelvic floor distress symptoms were compared between two groups according to the severity of striae gravidarum. Univariate analysis was carried out using appropriate tests; PFDI scores were compared between the groups using the Mann-Whitney test. RESULTS: Women with striae gravidarum were significantly older (31.06 vs. 28.83 years, p < 0.01), had a lower body mass index (27.5 vs. 30.98, p < 0.01), and gave birth to smaller neonates (3155 vs. 3389 g, p < 0.01). In addition, the overall and median PFDI-20 scores differed between the groups (with severe SG having the highest median score of 20 and those with milder SG having a score of 16 compared to 14 in those without SG). A distinct association between the PFDI-20 score and SG severity was not demonstrated (p = 0.63). CONCLUSIONS: In our population, an association was demonstrated between pelvic floor distress symptoms and the presence of striae gravidarum. However, following a linear regression model, no statistically significant association between SG severity and total PFD-20 score was seen. Our findings strengthen the hypothesis of common connective tissue involvement in the pathophysiology of both conditions.

Validation and cross-cultural adaptation of the Brazilian Portuguese version of the questionnaire for the assessment of pelvic floor disorders and their risk factors during pregnancy and postpartum.

INTRODUCTION AND HYPOTHESIS: Pelvic floor dysfunction may be treated and prevented during pregnancy and postpartum, as it decreases women's quality of life. The aim of the present study was to translate and validate the Brazilian Portuguese questionnaire for the assessment of pelvic floor disorders and their risk factors during pregnancy and postpartum. METHODS: This is a cross-sectional study. Two translators fluent in German translated the German version of the questionnaire into English. The back translation was performed by two other translators. The final version was tested on Brazilian pregnant/puerperal women. The participants answered the questionnaire twice, with an interval of 7-10 days between sessions. They also completed the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). To evaluate the test-retest reliability, we used the intraclass correlation coefficient (ICC), Cronbach's alpha coefficient, to test the internal consistency, and Pearson's linear correlation to assess construct validity. RESULTS: Sixty-six women were included (77% pregnant; 23% puerperal women), with a mean age of 26.5 ± 5.8 years and a body mass index of 26.4 ± 5.7 kg/cm2. There were no missing ceiling or floor effects. The construct validity presented a moderate correlation with the role physical domain of the SF-36 (r = -0.48), the ICC test-retest showed good reliability of 0.72, and the internal consistency was 0.71. CONCLUSIONS: These results provide evidence that the questionnaire for the assessment of pelvic floor disorders and their risk factors during pregnancy and postpartum is a valid and reliable instrument when utilized in Brazilian pregnant and postpartum women.

What do female university students know about pelvic floor disorders? A cross-sectional survey.

INTRODUCTION AND HYPOTHESIS: Pelvic floor dysfunction (PFD) is common in women but few seek medical attention. Poor recognition of the condition as pathological and unawareness of treatments may account for low consultation rates. METHODS: This cross-sectional study was based on an online survey that was responded to in February and March 2020 by 768 female university students. Knowledge of PFD was assessed using the Prolapse and Incontinence Knowledge Questionnaire (PIKQ). Descriptive and inferential analyses were performed using IBM-SPSS (V26.0). RESULTS: Respondents had poor knowledge of PFD and especially of pelvic organ prolapse. Health science students (n = 531; 69.1%) obtained significantly higher scores (p < 0.001) than other students (n = 237; 30.9%). Those who had received information on how to perform pelvic floor muscle training were more likely to score higher than those who had not received previous information. CONCLUSIONS: While health science students have better knowledge of PFD than other students, university students in general are little aware of PFD. Most students considered the issue of PFD to be important and wanted more information. Our findings may be useful in planning strategies to raise women's awareness of PFD and its prevention and treatment.

Elite female athletes' experiences of symptoms of pelvic floor dysfunction: A systematic review.

INTRODUCTION AND AIMS: Pelvic floor dysfunction (PFD) is a collection of signs, symptoms and conditions affecting the pelvic floor and urinary incontinence (UI) is the most common type of PFD. Recent systematic reviews have indicated a higher prevalence of UI among female athletes compared to their non-athletic counterparts. To date, no review has been undertaken to investigate female athletes' experiences of PFD. This review aims to offer insight and understanding, through aggregation, summary, synthesis and interpretation of findings from studies that report elite female athletes' experiences of symptoms of PFD. METHODS: The review protocol was registered in PROSPERO in August 2020. A systematic search was conducted in Embase, MEDLINE (OVID), Cochrane Library, CINAHL, PsycINFO and Web of Science for studies published in the English language reporting elite female athletes' experiences of symptoms of PFD. This review included primary research studies that involved elite female athletes of any age or ethnicity. RESULTS: Of the 1922 citations retrieved in the search, 32 studies met the methodological criteria for data extraction and analysis. Five main themes emerged: (1) triggers for symptoms of PFD; (2) strategies adopted by athletes to manage/mitigate symptoms of PFD; (3) impact on QOL/daily life; (4) impact on performance; (5) impact on emotions. CONCLUSIONS: The findings of this review suggest a need to further explore the experiences of PFD among elite female athletes and it is suggested that future research should adopt qualitative methods or incorporate a qualitative component.
