Abstract
OBJECTIVE We aimed to investigate changes in the elastic properties of levator ani muscle (LAM) and external anal sphincter (EAS) during pregnancy using shear wave elastography (SWE). Our secondary objective was to examine the association between the elastic properties of pelvic floor muscles (PFM) and perineal tears at childbirth. METHODS This was a prospective monocentric study, including nulliparous women. Three visits were planned (14-18, 24-28, and 34-38 weeks) with a SWE assessment of the LAM and EAS at rest and during Valsalva maneuver. Then, we collected data about the delivery's characteristics. Assessments were performed using an Aixplorer V12® device (SL 18-5 linear probe) using a transperineal approach, reporting the shear modulus in kPa. We looked for changes in PFM's elastic properties during pregnancy using one-way ANOVA for repeated measures. We compared the mean shear modulus in late pregnancy for each muscle and condition between women with an intact perineum at delivery and those with a perineal tear using Student's t test. RESULTS Forty-seven women were considered. Forty-five women had vaginal delivery of which 38 (84.4%) had perineal tears. We did not report any significant changes in the elastic properties of PFM during pregnancy. Women with an intact perineum at delivery had a stiffer EAS at Valsalva maneuver in late pregnancy (27.0 kPa vs. 18.2 kPa; p < 0.005). CONCLUSIONS There were no significant changes in the elastic properties of the PFM in pregnancy. Stiffer EAS in late pregnancy appears to be associated with a lower incidence of perineal tears.

Systematic Review and Meta-analysis of the Prevalence of Levator Ani Avulsion with Obstetric Anal Sphincter Injury and its Effects on Pelvic Floor Dysfunction. Int Urogynecol J 2024; 35:955-965. [PMID: 38523161 DOI: 10.1007/s00192-024-05756-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Accepted: 02/08/2024] [Indexed: 03/26/2024]
Abstract
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.

Abstract
OBJECTIVES Women have a 11% lifetime risk of undergoing surgery for vaginal prolapse. Levator ani muscle (LAM) avulsion is one etiological factor associated with primary and recurrent pelvic organ prolapse. Pelvic organ prolapse has been shown to greatly affect the quality of life and well-being of women. Conduct a meta-analysis identifying risk factors associated with LAM avulsion recognised on transperineal ultrasound (TPUS) or magnetic resonance imaging (MRI) in primiparous women after vaginal birth. STUDY DESIGN OVID Medline, Embase and the Cochrane Library from inception to January 2021 were searched. Review Manager 5.3 (The Cochrane Collaboration) was used to analyse data. Odds ratios (OR) with 95% confidence intervals (95% CIs) were calculated. The heterogeneity among studies was calculated using the I2statistic. RESULTS Twenty-five studies were eligible for inclusion (n = 9333 women). Major LAM avulsion was diagnosed in an average of 22 % (range 12.7-39.5 %) of cases. Twenty-two studies used TPUS and three used MRI to diagnose avulsion. Modifiable and non-modifiable risk factors were identified. Significant predictors identified were forceps (OR 6.25 [4.33 - 9.0]), obstetric anal sphincter injuries (OR 3.93 [2.85-5.42]), vacuum (OR 2.41 [1.40-4.16]), and maternal age (OR 1.06 [1.02-1.10]). CONCLUSIONS This is the first meta-analysis of both modifiable and non-modifiable risk factors associated with LAM avulsion. This information could be used to develop a clinically applicable risk prediction model to target postnatal women at risk of LAM avulsion with a view to prevent the onset of pelvic floor organ prolapse.

Abstract
Assisted vaginal birth rates are falling globally with rising cesarean delivery rates. Cesarean delivery is not without consequence, particularly when carried out in the second stage of labor. Cesarean delivery in the second stage is not entirely protective against pelvic floor morbidity and can lead to serious complications in a subsequent pregnancy. It should be acknowledged that the likelihood of morbidity for mother and baby associated with cesarean delivery increases with advancing labor and is greater than spontaneous vaginal birth, irrespective of the method of operative birth in the second stage of labor. In this article, we argue that assisted vaginal birth is a skilled and safe option that should always be considered and be available as an option for women who need assistance in the second stage of labor. Selecting the most appropriate mode of birth at full dilatation requires accurate clinical assessment, supported decision-making, and personalized care with consideration for the woman's preferences. Achieving vaginal birth with the primary instrument is more likely with forceps than with vacuum extraction (risk ratio, 0.58; 95% confidence interval, 0.39-0.88). Midcavity forceps are associated with a greater incidence of obstetric anal sphincter injury (odds ratio, 1.83; 95% confidence interval, 1.32-2.55) but no difference in neonatal Apgar score or umbilical artery pH. The risk for adverse outcomes is minimized when the procedure is conducted by a skilled accoucheur who selects the most appropriate instrument likely to achieve vaginal birth with the primary instrument. Anticipation of potential complications and dynamic decision-making are just as important as the technique for safe instrument use. Good communication with the woman and the birthing partner is vital and there are various recommendations on how to achieve this. There have been recent developments (such as OdonAssist) in device innovation, training, and strategies for implementation at a scale that can provide opportunities for both improved outcomes and reinvigoration of an essential skill that can save mothers' and babies' lives across the world.

Abstract
OBJECTIVE To provide guidelines for the pelvic clinical exam in gynecology and obstetrics. MATERIAL AND METHODS A multidisciplinary experts consensus committee of 45 experts was formed, including representatives of patients' associations and users of the health system. The entire guidelines process was conducted independently of any funding. The authors were advised to follow the rules of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. METHODS The committee studied 40 questions within 4 fields for symptomatic or asymptomatic women (emergency conditions, gynecological consultation, gynecological diseases, obstetrics, and pregnancy). Each question was formulated in a PICO (Patients, Intervention, Comparison, Outcome) format and the evidence profiles were produced. The literature review and recommendations were made according to the GRADE® methodology. RESULTS The experts' synthesis work and the application of the GRADE method resulted in 27 recommendations. Among the formalized recommendations, 17 present a strong agreement, 7 a weak agreement and 3 an expert consensus agreement. Thirteen questions resulted in an absence of recommendation due to lack of evidence in the literature. CONCLUSIONS The need to perform clinical examination in gynecological and obstetrics patients was specified in 27 pre-defined situations based on scientific evidence. More research is required to investigate the benefit in other cases.

Abstract
INTRODUCTION AND HYPOTHESIS The failure of the levator hiatus (LH) and urogenital hiatus (UGH) to remain closed is not only associated with pelvic floor disorders, but also contributes to recurrence after surgical repair. Pregnancy and vaginal birth are key events affecting this closure. An understanding of normal and failed hiatal closure is necessary to understand, manage, and prevent pelvic floor disorders. METHODS This narrative review was conducted by applying the keywords "levator hiatus" OR "genital hiatus" OR "urogenital hiatus" in PubMed. Articles that reported hiatal size related to pelvic floor disorders and pregnancy were chosen. Weighted averages for hiatal size were calculated for each clinical situation. RESULTS Women with prolapse have a 22% and 30% larger LH area measured by ultrasound at rest and during Valsalva than parous women with normal support. Women with persistently enlarged UGH have 2-3 times higher postoperative failure rates after surgery for prolapse. During pregnancy, the LH area at Valsalva increases by 29% from the first to the third trimester in preparation for childbirth. The enlarged postpartum hiatus recovers over time, but does not return to nulliparous size after vaginal birth. Levator muscle injury during vaginal birth, especially forceps-assisted, is associated with increases in hiatal size; however, it only explains a portion of hiatus variation-the rest can be explained by pelvic muscle function and possibly injury to other level III structures. CONCLUSIONS Failed hiatal closure is strongly related to pelvic floor disorders. Vaginal birth and levator injury are primary factors affecting this important mechanism.

Abstract
Stress urinary incontinence is a common disease in middle-aged and elderly women, which seriously affects the physical and mental health of the patients. For this reason, researchers have carried out a large number of studies on stress urinary incontinence. At present, it is believed that the pathogenesis of the disease is mainly due to changes related to age, childbirth, obesity, constipation and other risk factors that induce changes in the urinary control anatomy, including the anatomical factors of the urethra itself, the anatomical factors around the urethra and the anatomical factors of the pelvic nerve. The combined actions of a variety of factors lead to the occurrence of stress urinary incontinence. This review aims to summarize the anatomical pathogenesis of stress urinary incontinence from the above three perspectives.

Abstract
OBJECTIVE To estimate the diagnostic test accuracy of magnetic resonance imaging (MRI) and pelvic floor ultrasound for levator ani muscle (LAM) avulsion in a general parous population, with view to establishing if ultrasound could substitute for MRI to diagnose LAM avulsion. METHODS This was a cross-sectional study of 135 women 4 years after their first delivery. Signs and symptoms of pelvic floor dysfunction were assessed using validated methods. All women underwent four-dimensional transperineal ultrasound (TPUS), three-dimensional endovaginal ultrasound (EVUS) and MRI. Images were acquired at rest, on pelvic floor muscle contraction (PFMC) and on maximum Valsalva maneuver, and analyzed by two blinded observers. Predefined cut-off values were used to diagnose LAM avulsion. In the absence of a reference standard, latent class analysis (LCA) was used to establish diagnostic test characteristics for LAM avulsion as the primary outcome measure. Secondary outcomes were kappa (κ) agreement between imaging techniques, intraclass correlation coefficients (ICC) for hiatal measurements at rest, on PFMC and on maximum Valsalva maneuver, and the association of LAM avulsion with signs and symptoms of pelvic floor dysfunction. RESULTS The prevalence of LAM avulsion was 23.0% for MRI, 11.1% for TPUS and 17.8% for EVUS. The prevalence of LAM avulsion using LCA was 15.7%. The sensitivity for LAM avulsion of TPUS (71% (95% CI, 50-90%)) and EVUS (91% (95% CI, 74-100%)) was lower than that of MRI (100% (95% CI, 84-100%)). The specificity of TPUS (100% (95% CI, 97-100%)) and EVUS (95% (95% CI, 91-99%)) was higher than that of MRI (91% (95% CI, 85-97%)). MRI and EVUS had high predictive values for the assessment of major LAM avulsion (positive predictive value (PPV), 95% and negative predictive value (NPV), 100%; PPV, 100% and NPV, 98%, respectively), while TPUS had high predictive values for minor LAM avulsion (PPV, 100% and NPV, 95%). Major LAM avulsion on MRI and EVUS was associated with anterior vaginal wall prolapse, which was not found for TPUS. The agreement in the diagnosis of LAM avulsion (κ, 0.69) and hiatal measurements (ICC, 0.60-0.81) was highest between MRI and EVUS. CONCLUSIONS Pelvic floor ultrasound can be implemented as a triage test to assess parous women for LAM avulsion because of its high specificity. Ultrasound cannot substitute for MRI because of its lower sensitivity. The predictive ability of ultrasound is moderate for the presence, and very good for the absence, of LAM avulsion. A positive test should be confirmed by a different observer or imaging technique. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
INTRODUCTION AND HYPOTHESIS The objective was to investigate the evolution of levator ani muscle (LAM) trauma over the first 9 months after birth and to evaluate their agreement between different assessment periods. METHODS From March 2017 to April 2019 we prospectively evaluated LAM states (intact, hematoma, partial or complete avulsion) of primiparous women after vaginal birth by using 4D translabial ultrasound (TLUS) at three different assessment periods. All women were examined 1-4 days (A1) and 6-10 weeks (A2) postpartum, and women with a trauma additionally 6-9 months postpartum (A3). Cohen's Kappa analysis was performed to evaluate the test agreement between the assessment periods. RESULTS Thirty-two percent of the women at A1 had a LAM trauma and 24% at A2. The higher number of LAM injuries at A1 can be explained by hematomas (14%), of which 51% spontaneously resolved at A2, 35% revealed themselves as partial, and 12% as complete avulsions. At A3, we observed anatomical improvement from complete to partial avulsions (23%) and few partial avulsions changed into an intact LAM (3%); none of the complete avulsions changed into an intact LAM. The agreement of 4D TLUS between A1 and A2 was moderate to good (0.64 for the right-sided LAM/0.60 for the left-sided LAM) and between A2 and A3 good to very good (0.76 right-sided/0.84 left-sided). CONCLUSIONS Levator ani muscle trauma can reliably be diagnosed during all assessment periods. However, the agreement between A1 and A2 was only moderate to good. This can be explained by hematomas inside the LAM that were only observed early postpartum. We observed some anatomical improvement at A3, but no complete avulsion improved to an intact LAM.

Abstract
OBJECTIVES The primary aim was to evaluate prospectively the natural history of levator ani muscle (LAM) avulsion 4 years following first delivery and its correlation with signs and symptoms of pelvic floor dysfunction (PFD). The secondary aim was to investigate the effect of a second vaginal delivery on the incidence of LAM avulsion and PFD. METHODS This was a prospective longitudinal study of nulliparous women recruited antenatally, who were assessed at 36 weeks' gestation and 3 months, 1 year and 4 years postpartum for signs and symptoms of PFD and presence of LAM avulsion. Pelvic floor muscle strength was assessed by digital palpation, and pelvic organ prolapse (POP) was assessed using the POP quantification (POP-Q) system. Validated questionnaires were used to evaluate urinary, bowel and sexual function and symptoms of POP. Transperineal ultrasound was performed to assess LAM integrity and hiatal biometry. Differences in signs and symptoms of PFD over time were evaluated using a linear mixed model, separately in women who had had one delivery and in those who had two or more deliveries during the study period. RESULTS Of 269 women recruited, 147 (55%) attended the 4-year follow-up and were examined at a mean interval of 3.8 ± 0.4 years after their first delivery. Of these, 74 (50%) had a subsequent delivery. The prevalence of LAM avulsion 4 years after a first vaginal delivery was 13%, with no difference between women who had one and those who had two or more vaginal deliveries. Women with an intact LAM and one or more deliveries showed no change in signs and symptoms of PFD at 4 years compared with the previous assessments. Of women with one vaginal delivery who were diagnosed with LAM avulsion 3 months or 1 year postpartum, those in whom the LAM avulsion was no longer evident at 4 years (42%) showed worsening of POP-Q measurements, whereas those with persistent LAM avulsion (58%) showed significant worsening in pelvic floor muscle strength and hiatal area on ultrasound. After a second vaginal delivery, no new avulsions were diagnosed, however, previous LAM avulsion became more extensive in 44% of women and hiatal area increased in women with persistent LAM avulsion. CONCLUSIONS The first vaginal delivery carries the greatest risk for LAM avulsion, with impact on signs of PFD 4 years later. A second vaginal delivery could result in deterioration of LAM avulsion, but no new avulsions were found. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Our main objective was to assess the intraoperator intersession reproducibility of transperineal ultrasound Shear Wave Elastography (SWE) to measure the levator ani muscle (LAM) elastic properties. Secondary objective was to compare reproducibility when considering the mean of three consecutives measurements versus one. In this prospective study involving non-pregnant nulliparous women, two visits were planned, with a measurement of the shear modulus (SM) on the right LAM at rest, during Valsalva maneuver and maximal contraction. Assessments were done with a transperineal approach, using an AIXPLORER device with a linear SL 18–5 (5-18 MHz) probe. For each condition, 3 consecutive measures were performed at each visit. The mean of the three measures, then the first one, were considered for the reproducibility by calculating intraclass correlation coefficient (ICC), and coefficient of variation (CV). Twenty women were included. Reproducibility was excellent when considering the mean of the 3 measures at rest (ICC = 0.90; CV = 15.7%) and Valsalva maneuver (ICC = 0.94; CV = 10.6%), or the first of the three measures at rest (ICC = 0.87; CV = 18.6%) and Valsalva maneuver (ICC = 0.84; CV = 19.9%). Reproducibility was fair for measurement during contraction. Transperineal ultrasound SWE is a reliable tool to investigate LAM elastic properties at rest and during Valsalva maneuver.

Abstract
Pelvic organ prolapse (POP) is a common gynecological benign disease occurring in middle-aged and elderly females. Its incidence increases every year. To date, the majority of studies investigating its etiology have not evaluated the underlying molecular mechanisms, which has caused substantial difficulties in the prevention, treatment and prognosis of POP. In the present narrative review, recent research studies concerning the molecular mechanisms of POP were systematically reviewed and the advances were summarized. The association between the incidence of POP and the reduction of the extracellular matrix, activation of oxidative stress, genetic susceptibility, denervation of the pelvic floor and reduction of estrogen infiltration were explored. POP is mainly associated with damage of pelvic floor muscles and connective tissue, which are directly caused by pregnancy and vaginal delivery. The majority of the molecular and genetic mutations associated with POP involve specific components of connective tissue synthesis and degradation. It is likely that macroscopic parameters, such as anatomy, lifestyle and reproductive factors, interact with microscopic parameters, such as physiology and genetics in the female pelvic floor, leading to POP. Additional research studies investigating the molecular mechanisms of POP should be performed, since they may aid public health strategies. In the present narrative review, a summary of these molecular mechanisms underlying the development of POP is provided. This included the relevant proteins and genes involved. On this basis, countermeasures were proposed.

Abstract
AIMS The primary aim of the present study was to assess the association between levator ani muscle (LAM) integrity and function on the one hand, and the risk of urinary incontinence (UI) on the other. A secondary objective was to assess the association between fundal pressure in the second stage of labor (Kristeller maneuver) and the risk of postpartum UI. METHODS In this prospective cohort study, women underwent a clinical and transperineal ultrasound examination at rest, at pelvic floor muscle contraction (PFMC), and at Valsalva maneuver 3-6 months after their first vaginal delivery. LAM avulsion and levator hiatal area (LHA) were evaluated. In addition, women were interviewed about the presence of UI, whether stress (SUI) or urgency (UUI). RESULTS Overall, data of 244 women were analyzed. SUI was reported in 50 (20.5%), while UUI was reported in 19 (7.8%) women. Women who reported SUI had a higher prevalence of LAM avulsion and less proportional reduction in LHA from rest to a maximum contraction in comparison to women with no SUI. Women who reported UUI had a greater LHA at rest, during contraction, and during maximal Valsalva in comparison to women without UUI. No significant association was found between the Kristeller maneuver and the incidence of any UI. CONCLUSION Levator ani avulsion and less proportional reduction of LHA with PFMC appear to be associated with a higher risk of postpartum urinary stress incontinence.

Abstract
OBJECTIVE In women with obstetric anal sphincter injuries, we compared the rate of major levator ani avulsion after forceps-assisted delivery versus spontaneous vaginal delivery. METHODS Prospective cohort of primiparous women with obstetric anal sphincter injuries. The primary outcome was the rate of major levator ani avulsion as measured by 3-dimensional transvaginal ultrasonography performed between 1 and 2 weeks postpartum. Secondary outcomes included ultrasonographic anteroposterior hiatal diameter, levator hiatal area, and levator-urethra gap, and differences in validated pelvic disorder questionnaires scores at 1 to 2 and 13 weeks postpartum. RESULTS Sixty-two women (30 spontaneous deliveries, 32 forceps deliveries) were included in the final analysis. After controlling for delivery variables, women who underwent forceps-assisted delivery were more likely to experience a major avulsion as compared with those who underwent spontaneous delivery (21/32, [65.6%] vs 8/30 [26.7%]; odds ratio, 5.9; 95% confidence interval, 1.5-24.5; P = 0.014). They were also more likely to have larger levator-urethra gaps bilaterally (P = 0.012, 0.016). After controlling for potential confounders, levator ani avulsion was independently associated with persistent anal incontinence symptoms at 13 weeks postpartum (P = 0.02). CONCLUSIONS In women with obstetric anal sphincter injuries, the risk of levator ani avulsion is almost 6 times higher after forceps-assisted vaginal delivery as compared with spontaneous vaginal delivery. In those with avulsion, recovery of anal continence is compromised, suggesting that adding insult (avulsion) to injury (obstetric anal sphincter injury) may have negative functional consequences.

Abstract
BACKGROUND Risks of pelvic organ prolapse and urinary incontinence increase after the first vaginal delivery. During the early postpartum period, a time of active regeneration and healing of the pelvic floor, women may be particularly vulnerable to greater pelvic floor loading. OBJECTIVE This prospective cohort study aimed to determine whether objectively measured moderate to vigorous physical activity in the early postpartum period predicts pelvic floor support and symptoms 1 year after the first vaginal birth. STUDY DESIGN We enrolled nulliparous women in the third trimester, later excluding those who had a cesarean or preterm delivery. Participants wore triaxial wrist accelerometers at 2 to 3 weeks and 5 to 6 weeks postpartum for ≥4 days. Primary outcomes, assessed 1 year postpartum, included (1) pelvic floor support on Pelvic Organ Prolapse Quantification examination, dichotomized as maximal vaginal descent of <0 cm (better support) vs ≥0 cm (worse support); and (2) pelvic floor symptom burden, considered positive with report of ≥1 bothersome symptom in ≥2 of 6 domains, assessed using the Epidemiology of Prolapse and Incontinence Questionnaire. The primary predictor was average daily moderate to vigorous physical activity. Because we could not eliminate women with pelvic floor changes before pregnancy, we modeled prevalence, rather than risk, ratios for each outcome using modified Poisson regression. RESULTS Of 825 participants eligible after delivery, 611 completed accelerometry and 1-year follow-up; 562 completed in-person visits, and 609 completed questionnaires. The mean age was 28.9 years (standard deviation, 5.01). The mean for moderate to vigorous physical activity measured in minutes per day was 57.3 (standard deviation, 25.4) and 68.1 (standard deviation, 28.9) at 2 to 3 weeks and 5 to 6 weeks, respectively. One year postpartum, 53 of 562 participants (9.4%) demonstrated worse vaginal support and 330 of 609 participants (54.2%) met criteria for pelvic floor symptom burden. In addition, 324 (53.1%), 284 (46.6%), 144 (23.6%), and 25 (4.1%) reported secondary outcomes of stress urinary incontinence, overactive bladder, anal incontinence, and constipation, respectively, and 264 (43.4%), 250 (41.0%), and 89 (14.6%) reported no, mild, or moderate to severe urinary incontinence, respectively. The relationship between moderate to vigorous physical activity and outcomes was not linear. On the basis of plots, we grouped quintiles of moderate to vigorous physical activity into 3 categories: first and second quintiles combined, third and fourth quintiles combined, and fifth quintile. In final multivariable models, compared with women in moderate to vigorous physical activity quintiles 3 and 4, those in the lower 2 (prevalence ratio, 0.55; 95% confidence interval, 0.31-1.00) and upper quintile (prevalence ratio, 0.70; 95% confidence interval, 0.35-1.38)) trended toward lower prevalence of worse support. However, we observed the reverse for symptom burden: compared with women in quintiles 3 and 4, those in the lower 2 (prevalence ratio, 1.20; 95% confidence interval, 1.02-1.41) and upper quintile prevalence ratio 1.34 (95% confidence interval, 1.11-1.61) demonstrated higher prevalence of symptom burden. Moderate to vigorous physical activity did not predict any of the secondary outcomes. The presence of a delivery factor with potential to increase risk for levator ani muscle injury did not modify the effect of moderate to vigorous physical activity on outcomes. CONCLUSION Except for support, which was worse in women with moderately high levels of activity, early postpartum moderate to vigorous physical activity was either protective or had no effect on other parameters of pelvic floor health. Few women performed substantial vigorous activity, and thus, these results do not apply to women performing strenuous exercise shortly after delivery.

Abstract
Purpose: To evaluate the morphology and biometry of pelvic floor structures 3 months after birth in women experiencing first- or second-degree perineal tears or undergoing episiotomy during labor.Material and methods: Prospective observational study including nulliparous women delivering at term with a clinical diagnosis of first- or second-degree perineal tears after birth or undergoing episiotomy. The role of Kristeller maneuver during labor in affecting pelvic structure and function is also explored. All women underwent 2D trans-perineal and 3D endovaginal or endoanal ultrasound 3 months after birth.Results: 115 women assessed 3 months after delivery were enrolled in the study. Compared with controls, women who experienced first-degree perineal tears had higher bladder neck-symphysis (versus 20.9 ± 4.9 versus 16.1 ± 4.9 mm, p = .017), bladder wall-pubic symphysis (22.4 ± 7.4 versus 14.2 ± 9.5 mm, p = .02) and anorectal angle-symphysis distance (12.5 ± 4.7 versus 9.3 ± 4.3 mm, p = .018). Furthermore, they have thicker internal and external anal sphincter. The incidence of partial right and left pubo-rectalis muscle avulsion was higher in women experiencing first-degree vaginal tear during labor (16.2 versus 0%, p = .004 for both). In women affected by second-degree tears, the occurrence of partial avulsion of the right and left pubo-rectalis muscle was 16.2%, while Oasis was detected in 10.8% of the cases. Women receiving Kristeller maneuver during labor had a higher incidence of either right or left puborectalis muscle avulsion.Conclusion: Women who had either first- and second-degree perineal tears or episiotomy show signs of abnormal pelvic morphometry on 3D rotational ultrasound 3 months after birth.

Abstract
Background Urinary incontinence is a bothersome symptom. Although the relationship between stress urinary incontinence (SUI) and vaginal delivery is established, the pathology underlying SUI after vaginal birth remains to be elucidated. Objectives To determine whether levator ani muscle avulsion predisposes for SUI in women. Search strategy Pubmed and Embase were searched for terms and their variations “levator ani muscle avulsion” and “urinary incontinence”, from inception until 5 November 2019. Selection criteria Inclusion criterion: studies describing the relationship between urinary incontinence and levator ani muscle avulsion in women at least 1 year after delivery. Exclusion criterion: studies only analyzing the urethral sphincter or hiatus dimensions. Data collection and analysis Odds ratios were used and if not available, were calculated as means of data synthesis, adjusted odds ratios if presented by the study, random‐effects model to compute a pooled estimate. Results Seven studies were included, accounting for 2388 women. Comparing women with and without levator ani muscle avulsion, the overall odds ratio for SUI is 0.87 (95% confidence interval 0.56–1.34), and after adjustment for possible confounders was 0.72 (95% confidence interval 0.40–1.30). Conclusion There is no relationship between levator ani muscle avulsion and SUI in women. A systematic review and meta‐analysis was conducted to evaluate the relationship between levator ani muscle avulsion and stress urinary incontinence, which could not be supported.

Abstract
BACKGROUND Fecal incontinence is a disabling condition affecting up to 20% of women. OBJECTIVE We investigated fecal incontinence assessment in both inflammatory bowel disease and non-inflammatory bowel disease patients to propose a diagnostic approach for inflammatory bowel disease trials. METHODS We searched on Pubmed, Embase and Cochrane Library for all studies on adult inflammatory bowel disease and non-inflammatory bowel disease patients reporting data on fecal incontinence assessment from January 2009 to December 2019. RESULTS In total, 328 studies were included; 306 studies enrolled non-inflammatory bowel disease patients and 22 studies enrolled inflammatory bowel disease patients. In non-inflammatory bowel disease trials the most used tools were the Wexner score, fecal incontinence quality of life questionnaire, Vaizey score and fecal incontinence severity index (in 187, 91, 62 and 33 studies). Anal manometry was adopted in 41.2% and endoanal ultrasonography in 34.0% of the studies. In 142 studies (46.4%) fecal incontinence evaluation was performed with a single instrument, while in 64 (20.9%) and 100 (32.7%) studies two or more instruments were used. In inflammatory bowel disease studies the Wexner score, Vaizey score and inflammatory bowel disease quality of life questionnaire were the most commonly adopted tools (in five (22.7%), five (22.7%) and four (18.2%) studies). Anal manometry and endoanal ultrasonography were performed in 45.4% and 18.2% of the studies. CONCLUSION Based on prior validation and experience, we propose to use the Wexner score as the first step for fecal incontinence assessment in inflammatory bowel disease trials. Anal manometry and/or endoanal ultrasonography should be taken into account in the case of positive questionnaires.

Abstract
OBJECTIVE The goal of this study was to evaluate differences in levator ani hematoma formation within 3 days of delivery between adult women after their first vaginal delivery and adult women who have had multiple vaginal deliveries. METHODS This was a cross-sectional study at a single institution from 2013 to 2015 using a high-resolution endovaginal ultrasound transducer to identify postvaginal delivery hematoma formation. Logistic regression was used to examine the association between hematoma formation and vaginal parity while considering potential confounders including induction, vaginal operative delivery, vaginal birth after cesarean, fetal weight, fetal head circumference, race and ethnicity, body mass index, age at delivery, gestational age, and length of second-stage labor. RESULTS Ninety women (46 vaginal-primiparous; 44 vaginal-multiparous) were included in this study. After adjusting for oxytocin use, length of second-stage labor, and body mass index, the odds of pelvic floor hematoma of 1000 mm3 or greater were 2.93 (95% confidence interval, 0.78-10.91) times greater in women after their first vaginal delivery compared with women with a history of multiple vaginal deliveries. The adjusted odds of pelvic floor hematoma of 1500 mm3 or greater were 6.02 (95% confidence interval, 1.09-33.24) times greater in vaginal-primiparous compared with vaginal-multiparous women. CONCLUSIONS Although the prevalence of pelvic floor hematoma was higher in vaginal-primiparous women than vaginal-multiparous women after vaginal delivery, hematomas were present in both groups. Future prospective studies are needed to evaluate the additive effect of multiple vaginal deliveries on the pelvic floor.

Abstract
INTRODUCTION The present study aimed first to investigate the change in prevalence of major levator ani muscle (LAM) defects, also called avulsions, from 6 weeks to 1 year postpartum, and second to assess maternal and obstetric risk factors for having persistent major LAM defects/avulsions at 1 year postpartum. MATERIAL AND METHODS This is a secondary analysis of data from a prospective cohort study including 300 nulliparous women at 17-19 weeks of gestation. Major LAM defects were diagnosed at 6 weeks and 1 year postpartum using transperineal ultrasonography. We defined persistent major LAM defects as a defect diagnosed both at 6 weeks and 1 year postpartum. Maternal and obstetric data were obtained from the hospital's electronic birth records. Pelvic floor muscle function was measured vaginally by manometer at 21 weeks of gestation. The main outcome measurement was change in prevalence of major LAM defects. Maternal and obstetric risk factors for having persistent major LAM defect were also assessed. RESULTS Prevalence of major LAM defects was 19.4% at 6 weeks and 10.4% at 1 year postpartum. No new major LAM defects were diagnosed at 1 year postpartum. Persisting major LAM defects were associated with longer second stage of labor (median 74.5 minutes vs median 48.0 minutes, P = .012) and higher neonatal birthweight (mean difference of 232.3 g, 95% confidence interval [CI] 21.5-443.1). Vacuum delivery was independently associated with persistent major LAM defects, adjusted OR 3.0 (95% CI 1.0-9.0). CONCLUSIONS There was a 50% reduction of sonographically diagnosed major LAM defects from 6 weeks to 1 year postpartum. This finding suggests that assessment of the major LAM 6 weeks postpartum may be too early to diagnose defects/avulsions. Long second stage of labor, high neonatal birthweight and vacuum delivery were associated with persistent major LAM defects/avulsions.

Abstract
Background Animal studies have reported an increase in pelvic floor muscle stiffness during pregnancy, which might be a protective process against perineal trauma at delivery. Our main objective is to describe the changes in the elastic properties of the pelvic floor muscles (levator ani, external anal sphincter) during human pregnancy using shear wave elastography (SWE) technology. Secondary objectives are as follows: i) to look for specific changes of the pelvic floor muscles compared to peripheral muscles; ii) to determine whether an association between the elastic properties of the levator ani and perineal clinical and B-mode ultrasound measures exists; and iii) to provide explorative data about an association between pelvic floor muscle characteristics and the risk of perineal tears. Methods Our prospective monocentric study will involve three visits (14–18, 24–28, and 34–38 weeks of pregnancy) and include nulliparous women older than 18 years, with a normal pregnancy and a body mass index (BMI) lower than 35 kg.m− 2. Each visit will consist of a clinical pelvic floor assessment (using the Pelvic Organ Prolapse Quantification system), an ultrasound perineal measure of the anteroposterior hiatal diameter and SWE assessment of the levator ani and the external anal sphincter muscles (at rest, during the Valsalva maneuver and during pelvic floor contraction), and SWE assessment of both the biceps brachii and the gastrocnemius medialis (at rest, extension and contraction). We will collect data about the mode of delivery and the occurrence of perineal tears. We will investigate changes in continuous variables collected using the Friedman test. We will look for an association between the elastic properties of the levator ani muscle and clinical / ultrasound measures using a Spearman test at each trimester. We will investigate the association between the elastic properties of the pelvic floor muscles and perineal tear occurrence using a multivariate analysis with logistic regression. Discussion This study will provide original in vivo human data about the biomechanical changes of pregnant women’s pelvic floor. The results may lead to an individualized risk assessment of perineal trauma at childbirth. Trial registration This study was registered on https://clinicaltrials.gov on July 26, 2018 (NCT03602196).

Abstract
Objective To improve pelvic floor recovery after vaginal delivery with daily supplementation of a specially formulated postpartum recovery supplement. Methods Within 48 hours of vaginal delivery, primipara women were randomized in a 1:1 ratio to receive daily oral supplementation for 6 weeks with either a combination of regular prenatal vitamin (PNV), leucine (4 g/day), zinc (30 mg/day) and omega-3 fatty acid (900 mg/day) (treatment group), or only a PNV daily (control group). Co-primary outcomes were vaginal squeeze pressure as measured by perineometer and levator muscle injury as measured by transperineal 3-dimensional tomographic ultrasound at 6 weeks postpartum. Results Twenty-six women in the control group and 27 in the treatment group completed the trial. Weak pelvic floor muscle strength was significantly less frequent in the treatment group compared to the control group at 6 weeks after delivery (28% vs. 58%, P=0.03). Both right and left-sided levator-urethra gap was significantly larger in the control group compared to the treatment group indicating more levator injury being present in the control group at 6 weeks after delivery. Anterior vaginal wall prolapse at or beyond the hymenal ring was significantly more common in the control group compared to the treatment group (19% vs. 0%, P=0.02). Significantly more women reported bothersome bulge symptoms in the control group compared to the treatment group at 6 weeks postpartum (19% vs. 0%, P=0.02). Conclusion Postpartum women who received a specially formulated postpartum recovery supplement had improved recovery of the pelvic floor after vaginal delivery.

Abstract
Introduction and hypothesis Pelvic floor muscle function plays an important role in female sexual functioning. Smaller genital hiatal dimensions have been associated with sexual dysfunction, mainly dyspareunia. On the other hand, trauma of the levator ani muscle sustained during childbirth is associated with increased genital hiatus, which potentially can affect sexual functioning by causing vaginal laxity. This study aims to determine the association between levator hiatal dimensions and female sexual dysfunction after first vaginal delivery. Methods This is a secondary analysis of a prospective observational study. Two hundred four women who had a first, spontaneous vaginal delivery at term between 2012 and 2015 were recruited at a minimum of 6 months postpartum. Thirteen pregnant women were excluded. We analyzed the association of total PISQ-12 score, as well as individual sexual complaints (desire, arousal, orgasm and dyspareunia), with levator hiatal dimensions at rest, with maximum Valsalva and during pelvic floor muscle contraction as measured by 4D transperineal ultrasound. Statistical analysis was performed using linear regression analysis and Mann-Whitney U test. Results One hundred ninety-one women were evaluated at a median of 11 months postpartum. There was no significant association between total PISQ-12 score and levator hiatal dimensions. Looking at individual sexual complaints, women with dyspareunia had significantly smaller levator hiatal area and anterior-posterior diameter on maximum Valsalva. By using multivariate logistic regression analysis however we found dyspareunia was not independently associated with levator hiatal dimensions. Conclusions After first vaginal delivery sexual dysfunction is not associated with levator hiatal dimensions as measured by 4D transperineal ultrasound.

Are women attending a midwifery-led birthing center at increased risk of anal sphincter injury? Int Urogynecol J 2020; 31:583-589. [PMID: 31901952 DOI: 10.1007/s00192-019-04218-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2019] [Accepted: 12/16/2019] [Indexed: 10/25/2022]
Abstract
INTRODUCTION AND HYPOTHESIS In recent years there has been renewed interest in midwifery-led care for women, with studies reporting similar neonatal outcomes despite lower rates of intervention in midwifery-led birthing centers. Research into obstetric anal sphincter injuries (OASI) in these birthing centers is scarce. The objective of this study was to compare the rate of OASI after spontaneous vaginal delivery in nulliparous women in consultant or midwifery-led units over a ten-year period. METHODS All spontaneous vaginal deliveries in nulliparous women from 2008 to 2017 were analyzed in a single-center retrospective study. Women who had neuraxial analgesia were excluded. The primary endpoint was OASI. Labor characteristics in both groups were compared, and a multiple regression model was created. RESULTS During the study period, there were 3260 spontaneous vaginal deliveries in nulliparous women; 75.7% (2467/3260) delivered in the consultant-led unit and 24.3% (793/3260) in the midwifery-led unit (MLU). Women delivering in the MLU had a greater risk of anal sphincter injury than those delivering in the CLU (4.9% [39/793] vs 2.5% [62/2467], OR 2.01, 95% CI 1.32 - 3.01). Significant risk factors that increased the risk of OASI on regression analysis were birthweight and delivery in the midwifery-led unit. CONCLUSIONS Women delivering in the midwifery-led unit appear to be at double the risk of OASI when compared to those delivering in the consultant-led unit. These results are in contrast to previous studies in midwifery-led centers. This difference may be site-specific and further research is required before these results form part of patient counseling.

Abstract
Background and objectives: As pelvic floor disorders are often difficult to assess thoroughly based on clinical examination alone, the use of imaging as a complementary technique is helpful. This study’s aim was to investigate by transperineal ultrasound (US) if there was any significant difference in the mobility of the bladder neck in women with stress urinary incontinence (SUI) without a cystocele and in those with SUI and an associated cystocele. The study also investigated whether the number of vaginal births and/or the heaviest newborn’s birth weight was correlated with the bladder neck mobility. Materials and Methods: A total of 71 women suffering from SUI were included in the study and divided into two groups based on the presence of a cystocele. Their bladder neck mobility was evaluated by transperineal US, calculating the distance from the inferior margin of the symphysis pubis to the bladder neck (SPBN), and the dorsocaudal linear movement (DLM), term used to illustrate the displacement of the bladder neck by subtracting rest and Valsalva values. GraphPad Prism 8 was used for statistical analysis. Results: Within both study groups, the SPBN values were significantly higher and the DLM values were significantly lower at rest as compared to Valsalva maneuver (p < 0.05). No significant difference between the groups regarding SPBN and DLM values at rest, Valsalva, or subtraction was demonstrated. A significant positive correlation was found between the bladder neck mobility and the heaviest newborn’s birth weight, regardless of the presence of a cystocele (p = 0.042). Conclusions: The presence of a cystocele had no significant impact on the bladder neck mobility measurements in patients with SUI. The heaviest newborn’s birth weight positively correlated with bladder neck hypermobility, as quantified by SPBN.

Abstract
INTRODUCTION Women, during the antenatal and post-partum period, report pelvic, low back pain, stress and urge urinary incontinence, colorectal dysfunction, and other co-morbidities that negatively affect health-related quality of life. Exercise and nutrition are important considerations for improving maternal health in this period. PURPOSE The purpose of this study was to examine the effects of a community-driven nutrition and exercise programme focused on pelvic floor and core stability, healthy nutrition, and breastfeeding counselling over an 8-week period on pelvic floor and urinary distress (UDI), prolapse and colorectal distress for antenatal and post-partum women with limited access to health care, and low socio-economic resources from a Midwestern Region of the United States. MATERIALS AND METHODS Purposive sample of 35 females, ages 18-44, were recruited for this prospective, preintervention to postintervention study, following ethical approval from Institutional Review Board and voluntary written consent from participants. The Health History Questionnaire, SF-36, Food Frequency Questionnaire, report of pelvic organ prolapse dysfunction (POPDI), colorectal-anal dysfunction (CRADI), and UDI as measured by the Pelvic Floor Distress Inventory (PFDI) were completed before and after intervention. RESULTS Thirty-five women (n = 35) 18 to 44 years old (mean age of 22.72 ± 3.45 years) completed the study. A significant difference was found from preintervention to postintervention scores means for PFDI total scores, CRADI individual scores, and UDI individual scores (p < .05). POPDI scores decreased preintervention to postintervention but were not significant. A significant improvement in healthy nutrition and breastfeeding postintervention was also found (z = 3.21, p = .001). Further analysis showed significant, but weak, correlation between parity and POPDI (r = .366, p = .033); between parity and UDI (r = .384, p = .03); and between parity and PFDI (r = .419, p = .014). DISCUSSION Our study found a significant reduction in pelvic floor dysfunction, urinary, and colorectal-anal distress symptoms and improvement in breastfeeding and healthy nutrition following an 8-week community-driven nutrition and exercise programme focused on pelvic floor and core stability, healthy nutrition, and breastfeeding counselling.

JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2019; 38:889-894. [PMID: 30203420 DOI: 10.1002/jum.14767] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/16/2018] [Revised: 06/25/2018] [Accepted: 06/26/2018] [Indexed: 06/08/2023]
Abstract
OBJECTIVES Three-/four-dimensional translabial ultrasound (US) is increasingly used to image the levator ani and anal sphincters, especially in the form of tomographic US. The aim of the study was to evaluate the validity of these published methods. METHODS This work was a retrospective analysis of datasets of 172 nulliparous women who attended 2 tertiary urogynecologic centers for symptoms of pelvic floor dysfunction between June 2012 and September 2016. All patients had a standardized interview, clinical examination, and 4-dimensional translabial US examination. An evaluation of volume data was performed by the first author, who was blinded against all clinical data, including parity. An assessment for levator avulsion and anal sphincter defects was performed using stored US volume data. RESULTS Data sets of 162 and 153 nulliparous women were available for levator and anal sphincter assessments, respectively. On the assessment by the first author, a complete avulsion was diagnosed in 3 nulliparas. On a review by 2 senior authors, 1 was judged as positive and the other 2 as normal. On the sphincter assessment, 2 significant external anal sphincter defects were detected. On the review, 1 was judged as false-positive. The second was judged as highly abnormal by all authors. Therefore, 1 nullipara each was diagnosed with avulsion and a significant external anal sphincter defect. CONCLUSIONS Published diagnostic criteria for levator avulsion and external anal sphincter trauma on tomographic US imaging are highly unlikely to result in false-positive findings. This finding supports the clinical validity of this method.

Abstract
OBJECTIVES To estimate the prevalence of, and explore the risk factors for, levator ani muscle (LAM) injury in women with clinically diagnosed obstetric anal sphincter injury (OASI). The secondary aim was to assess the association between LAM injury and pelvic floor muscle contraction, anal incontinence (AI) and urinary incontinence (UI) in women with OASI. METHODS This was a cross-sectional study of 250 women with OASI, recruited between 2013 and 2015 from a tertiary referral center at Croydon University Hospital, UK. AI symptoms were assessed using the modified St Mark's incontinence score and UI was assessed using the International Consultation on Incontinence modular Questionnaire for Urinary Incontinence - Short Form. All participants underwent three/four-dimensional transperineal ultrasound at rest and on maximum pelvic floor muscle contraction. Major LAM injury was defined as a unilateral or bilateral defect in all three central slices on tomographic ultrasound imaging. Muscle contraction was assessed using the modified Oxford scale (MOS) and measured on ultrasound as the proportional change in the anteroposterior (AP) levator hiatal diameter between rest and contraction. Multivariable logistic regression analysis was used to study risk factors for LAM injury. Differences in contraction and AI and UI symptoms between women with intact and those with injured LAM were studied using multivariable ANCOVA and the Mann-Whitney U-test. RESULTS Of the 248 women with OASI for whom ultrasound volumes of adequate quality were available, 29.4% were found to have major LAM injury. The prevalence of LAM injury was 23.6% after normal vaginal delivery and 40.2% after operative vaginal delivery (adjusted odds ratio, 4.1 (95% CI, 1.4-11.9); P = 0.01). LAM injury was associated with weaker pelvic floor muscle contraction, with an adjusted mean difference for proportional change in AP diameter of 5.0 (95% CI, 3.0-6.9) and MOS of 0.6 (95% CI, 0.3-0.9) (P < 0.001 for both). AI and UI symptom scores were similar between women with intact and those with injured LAM. CONCLUSIONS Operative vaginal delivery was a risk factor for LAM injury in women with OASI. LAM injury was associated with weaker pelvic floor muscle contraction. Special attention is recommended for women with OASI and LAM injury, as they are at high risk for future pelvic floor disorders. The benefits of implementation of an intensive, focused and structured pelvic floor rehabilitation program need to be evaluated in these women. Copyright © 2018 ISUOG.

Abstract
OBJECTIVE To study possible associations between pelvic floor muscle contraction, levator ani muscle (LAM) trauma and/or pelvic organ prolapse (POP) ≥ Stage 2 in parous women recruited from a general population. METHODS This was a secondary analysis of data from a cross-sectional study of 608 parous women from a general population examined using the POP quantification system (POP-Q) and three-dimensional/four-dimensional transperineal ultrasound for identification of LAM macrotrauma (avulsion) and microtrauma (distension of levator hiatal area > 75th percentile on Valsalva maneuver). Muscle contraction was assessed using the modified Oxford scale (MOS), perineometry and ultrasound measurement of proportional change of anteroposterior hiatal diameter and levator hiatal area at rest and on pelvic floor muscle contraction. The Mann-Whitney U-test was used to study associations between pelvic floor muscle contraction, LAM trauma and POP. RESULTS Women with macrotrauma (n = 113) had significantly weaker median pelvic floor muscle contraction, as measured using MOS and perineometry, than did women with an intact LAM (n = 493) (contraction strength was 1.5 (range, 0.0-5.0) vs 3.5 (range, 0.0-5.0) on MOS, and vaginal squeeze pressure was 15.0 (range, 0.0-78.0) cmH2 O vs 28.0 (range, 0.0-129.0) cmH2 O on perineometry; P < 0.001). This was also demonstrated by ultrasound measurement, with a proportional change in hiatal area of 19.9% (range, 4.1-48.0%) vs 34.0% (range, 0.0-64.0%) (P < 0.001) and proportional change in anteroposterior diameter of 16.2% (range, -5.7 to 42.6%) vs 26.0% (range, -3.4 to 49.4%) (P < 0.001). No statistically significant difference between women with (n = 65), and those without (n = 378), microtrauma was found after excluding women with macrotrauma. Women with POP had weaker muscle contraction than those without; in those with POP-Q ≥ 2 (n = 275) compared with those with POP-Q < 2 (n = 333), muscle contraction strength was 3.0 (range, 0.0-5.0) vs 3.5 (range, 0.0-5.0) on MOS, vaginal squeeze pressure was 21.0 (range, 0.0-98.0) cmH2 O vs 28.0 (range, 3.0-129.0) cmH2 O on perineometry, proportional change in hiatal area was 29.6% (range, 0.0-60.9%) vs 33.8% (range, 0.0-64.4%) and proportional change in anteroposterior diameter was 22.8% (range, -5.7 to 49.4%) vs 25.7% (range, -3.4 to 49.4%) (P < 0.001 for all). CONCLUSIONS LAM macrotrauma was associated with weaker pelvic floor muscle contraction measured using palpation, perineometry and ultrasound. Women with POP had weaker contraction than did women without POP. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd.

Long-term risks of stress and urgency urinary incontinence after different vaginal delivery modes. Am J Obstet Gynecol 2019; 220:181.e1-181.e8. [PMID: 30391444 DOI: 10.1016/j.ajog.2018.10.034] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2018] [Revised: 10/08/2018] [Accepted: 10/24/2018] [Indexed: 11/22/2022]
Abstract
BACKGROUND Although operative delivery increases the risk of immediate pelvic floor trauma, no previous studies have adequately compared directly the effects of different kinds of instrumental vaginal deliveries on stress urinary incontinence and/or urgency urinary incontinence. OBJECTIVE(S) The objectives of the study were to estimate and compare the impact of different kinds of vaginal deliveries, including spontaneous, vacuum, and forceps, on stress and urgency urinary incontinence. STUDY DESIGN All women aged 20 years or older, living in 1 county in Norway were invited to participate in 2 surveys addressing stress and urgency urinary incontinence using validated questions, "Do you leak urine when you cough, sneeze, laugh, or lift something heavy?" and "Do you have involuntary loss of urine in connection with sudden and strong urge to void?" with response options yes or no. Incontinence data were linked to the Medical Birth Registry of Norway. For this study, we included only women who had a history of vaginal birth(s). Case definitions for stress and urgency urinary incontinence were moderate to severe based on Sandvik Severity Index (slight, moderate, severe). We adjusted analyses for age, parity, body mass index, and time since last delivery and addressed effect modification, including an age threshold of 50 years. RESULTS The final analysis included 13,694 women of whom 12.7% reported stress urinary incontinence and 8.4% urgency urinary incontinence. Among women aged younger than 50 years, there was a statistically significant difference in the risk of stress urinary incontinence for forceps delivery (odds ratio, 1.42, 95% confidence interval, 1.09-1.86, absolute difference 5.0%) but not for vacuum (odds ratio, 0.80, 95% confidence interval, 0.59-1.09) when compared with spontaneous vaginal delivery. Among women aged younger than 50 years, forceps also had increased risk for stress urinary incontinence (odds ratio, 1.76, 95% confidence interval, 1.20-2.60) when compared with vacuum. There was no association of stress or urgency urinary incontinence with mode of delivery in women aged 50 years or older. CONCLUSION For women aged younger than 50 years, forceps delivery is associated with significant increased long-term risk of stress urinary incontinence compared with other vaginal deliveries.

Contraction of the levator ani muscle during Valsalva maneuver (coactivation) is associated with a longer active second stage of labor in nulliparous women undergoing induction of labor. Am J Obstet Gynecol 2019; 220:189.e1-189.e8. [PMID: 30321525 DOI: 10.1016/j.ajog.2018.10.013] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2018] [Revised: 10/02/2018] [Accepted: 10/07/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND The Valsalva maneuver is normally accompanied by relaxation of the levator ani muscle, which stretches around the presenting part, but in some women the maneuver is accompanied by levator ani muscle contraction, which is referred to as levator ani muscle coactivation. The effect of such coactivation on labor outcome in women undergoing induction of labor has not been previously assessed. OBJECTIVE The aim of the study was to assess the effect of levator ani muscle coactivation on labor outcome, in particular on the duration of the second and active second stage of labor, in nulliparous women undergoing induction of labor. STUDY DESIGN Transperineal ultrasound was used to measure the anteroposterior diameter of the levator hiatus, both at rest and at maximum Valsalva maneuver, in a group of nulliparous women undergoing induction of labor in 2 tertiary-level university hospitals. The correlation between anteroposterior diameter of the levator hiatus values and levator ani muscle coactivation with the mode of delivery and various labor durations was assessed. RESULTS In total, 138 women were included in the analysis. Larger anteroposterior diameter of the levator hiatus at Valsalva was associated with a shorter second stage (r = -0.230, P = .021) and active second stage (r = -0.338, P = .001) of labor. Women with levator ani muscle coactivation had a significantly longer active second stage duration (60 ± 56 vs 28 ± 16 minutes, P < .001). Cox regression analysis, adjusted for maternal age and epidural analgesia, demonstrated an independent significant correlation between levator ani muscle coactivation and a longer active second stage of labor (hazard ratio, 2.085; 95% confidence interval, 1.158-3.752; P = .014). There was no significant difference between women who underwent operative delivery (n = 46) when compared with the spontaneous vaginal delivery group (n = 92) as regards anteroposterior diameter of the levator hiatus at rest and at Valsalva maneuver, nor in the prevalence of levator ani muscle coactivation (10/46 vs 15/92; P = .49). CONCLUSION Levator ani coactivation is associated with a longer active second stage of labor.

Abstract
BACKGROUND Although the effectiveness of pelvic floor muscle training in women with prolapse has been demonstrated in several studies, there seem to be subgroups of responders and nonresponders. OBJECTIVE The objective of this study was to identify factors that predict treatment success in women receiving pelvic floor muscle training for prolapse. DESIGN The design was a secondary analysis of data from 2 randomized controlled trials comparing conservative prolapse treatments. METHODS After 12 months, 172 women subjectively assessed treatment success ("better") or failure ("the same" or "worse"). Potential predictors were identified by a literature search and by consultation with experts in the field of urogynecology and pelvic floor muscle training. The relationship between potential predictors and treatment success was explored using logistic regression analysis. RESULTS Treatment was successful in 94 women (55%) and unsuccessful in 78 women (45%). The presence of ≥1 indicators of obstetric trauma (eg, high birth weight, episiotomy, perineal laceration during vaginal delivery, forceps delivery, or vacuum extraction) (odds ratio = 4.4; 95% CI = 1.6-12.0) and younger age (odds ratio = 0.94 per year; 95% CI = 0.9-1.0) independently predicted treatment success. The area under the receiver operating characteristic curve for the final model was 0.65 (95% CI = 0.57-0.74), and the model explained 11.7% of the variance. LIMITATIONS Although attempts were made to include all relevant predictors, the selection or operationalization of variables could have been incomplete or insufficient. CONCLUSIONS Identifying women who have prolapse and are likely to benefit most from pelvic floor muscle training is of great importance to clinical practice. In this study, 2 factors that independently predicted favorable outcomes were identified with this management approach. However, further research is needed to identify other predictive factors and to validate a new model in another population.

Abstract
Background Pelvic floor dysfunctions (PFDs) affect the female population, and the postpartum period can be related to the onset or aggravation of the disease. Early identification of the symptoms and the impact on quality of life can be achieved through assessment instruments. Objective The purpose of this systematic review is to evaluate questionnaires used to assess PFD in the postpartum period. Methods A systematic review study was conducted, following Preferred Reporting Items for the Systematic Reviews and Meta-Analyses (PRISMA) criteria, using the databases: PubMed, Biblioteca Virtual de Saúde (BVS), Web of Science, and Scopus, and the keywords PFD or pelvic floor disorders, postpartum or puerperium, and questionnaire. Articles published up till May 2018 were included, searching for articles using validated questionnaires for the evaluation of PFDs in postpartum women. The articles included were evaluated according to a checklist, and the validation studies and translated versions of the questionnaires were identified. Results The search of the databases resulted in 359 papers, and 33 were selected to compose this systematic review, using nine validated questionnaires to assess PFDs in the postpartum period: International Consultation on Incontinence Questionnaire – Vaginal Symptoms (ICIQ-VS), Pelvic Floor Distress Inventory 20 (PFDI-20), Pelvic Floor Impact Questionnaire (PFIQ-7), PFDI-46, Pelvic Floor Impact Questionnaire (PFIQ-31), Pelvic Floor Bother Questionnaire (PFBQ), Female Pelvic Floor Questionnaire, electronic Personal Assessment Questionnaire – Pelvic Floor, and PFD questionnaire specific for pregnancy and postpartum. The most frequently reported questionnaires included PFDI-20, PFIQ-7, and ICIQ-VS and are recommended by ICI. In addition, the review identified a specific questionnaire, recently developed, to access PFD during pregnancy and postpartum. Conclusion The questionnaires used to evaluate PFD during postpartum period are developed for general population or urology/gynecology patients with incontinence and reinforce the paucity of highly recommended questionnaires designed for postpartum, in order to improve early and specific approach for this period of life.

Abstract
INTRODUCTION AND HYPOTHESIS Pregnancy and delivery are well-established risk factors for pelvic floor dysfunction (PFD), but the physiopathology, such as the delivery route, is not well understood. This study evaluated the impact of delivery route on the pelvic floor muscles via 3D ultrasound. METHODS This review is registered in the PROSPERO database. The criteria for inclusion were prospective studies with 3D translabial ultrasound assessment in primigravida women during pregnancy and postpartum published in English, Spanish or Portuguese between 1980 and 2016. We excluded studies that did not include the topic of urogenital hiatus measurement and literature reviews. The MeSH terms were obstetric delivery, postpartum period, labor, parturition, three-dimensional images, ultrasonography, pelvic floor, and pelvic floor disorders. RESULTS The search retrieved 155 articles. After analysis, 6 articles were included. Four studies showed that vaginal delivery (VD) was associated with a larger hiatal area. One study associated the hiatal area with levator ani muscle (LAM) defects in VD. Four articles evaluated the bladder neck, 3 of which showed a significant increase in bladder neck mobility associated with VD and 1 showed decreased bladder neck elevation, not associated with the delivery mode; the first 3 articles all evaluated LAM injuries and showed an association between VD and LAM injury. Women who underwent VD presented defects of the puborectalis muscle. CONCLUSIONS Vaginal delivery was associated with a higher number of LAM injuries, puborectalis defects, increased bladder neck mobility, and enlargement of the hiatal area.

Abstract
We observed the effects of physical rehabilitation therapy combined with medication on pelvic floor dysfunction (PFD). We collected the medical records of 84 maternal patients with PFD who received treatment at the Affiliated Hospital of Hebei University between May 2015 and October 2016. These patients were randomly divided into two groups, the control group (n=42) and observation group (n=42). In the control group, patients received conventional physical rehabilitation therapy while in observation group, patients received the shixiao powder combined with siwu decoction in addition to the physical rehabilitation. The therapeutic effects were compared between the two groups. The total effective rate of the observation group was 97.6%, which was significantly higher than 78.6% in the control group (P<0.05). In observation group, the index scores of pelvic floor function under rest state, such as electromyo-graphy amplitude, contraction force, coordinate strength and urine flow rate, were significantly higher than those in control group (P<0.05). The rate of Grade II perineal muscle strength in the observation group was 7.32%, which was significantly lower than 47.62% in control group (P<0.05). In observation group, the rates of Grade III and Grade IV muscle strength were respectively 43.91 and 29.26%, which were significantly higher than those in control group (P<0.05). Before the administration of treatment, there were no significant differences in the comparison of the urinary incontinence and sexual life quality of patients between the two groups (P>0.05). In observation group, after treatment, the rehabilitation effects of urinary incontinence and sexual life quality at 3 months post-delivery were significantly better than those in control group (P<0.05). Before treatment, there were no significant differences in the comparison of levels of C-reactive protein (CRP) and interleukin-10 (IL-10) between the two groups (P>0.05), however, after treatment, the levels of CRP and IL-10 of patients in observation group were significantly lower than those in control group (P<0.05). In the observation group, the incidence rate of complications (7.14%) were significantly lower than that in control group (23.81%; P<0.05). Therefore, physical rehabilitation therapy combined with the shixiao powder and siwu decoction exhibits significant efficacy in the treatment of PFD by effectively improving the pelvic floor functions, increasing perineal muscle strength, and decreasing expression levels of inflammatory factors, which can significantly ameliorate life quality and reduce the incidence rate of complications. Thus, this treatment method shows great application value in clinical practice.

Abstract
During the last decade, there has been a huge advancement in the use of transperineal ultrasound (TPU) in the field of obstetrics and gynecology. Its main applications in obstetrics include the monitoring of fetal progression in labor and recently the assessment of maternal pelvic dimensions, whereas in gynecology, TPU is at present widely used for the evaluation of the female pelvic floor, opening new boundaries for the assessment of pelvic floor disorders. The association of volumetric three-dimensional techniques has largely contributed to the remarkable progress that has occurred in the use of TPU. The aim of this paper is to offer an overview of the advantages, challenges and future perspectives of the use of TPU for women’s imaging.

Abstract
Pelvic organ prolapse is a fairly common condition that imposes significant symptoms, diminished quality of life, social burden, financial expense, and surgical risk on women. As evidence supporting the benefit of pelvic-floor muscle training in nonsurgical management of pelvic organ prolapse grows, physical therapists are becoming a provider of choice interacting with women affected by pelvic organ prolapse. This perspective article will review recent research on tissue characteristics of 3 key components of pelvic organ support: skeletal muscle, ligament, and vaginal wall. This information will be summarized as implications for physical therapists. An improved understanding of pelvic-floor tissue in women with and without pelvic organ prolapse will provide a more comprehensive appreciation of the interaction of multiple systems in the disorder.
