[PMID: 36107230 DOI: 10.1007/s00404-022-06769-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: 05/13/2022] [Accepted: 08/12/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND Most women suffer from perineal trauma during childbirth, whether it is natural tears or episiotomy. OBJECTIVES To perform a systematic review and network meta-analysis investigating the effectiveness of different PFMT relevant strategies in the prevention of perineal trauma. SEARCH STRATEGY PubMed, Embase, the Cochrane Library, CINAHL, CNKI, CBM, WANFANG DATABASE, and ClinicalTrials.gov were searched for citations published in any language from inception to 1 July 2021. SELECTION CRITERIA Randomized controlled trials (RCTs) of PFMT relevant prevention strategies for preventing perineal trauma during childbirth. DATA COLLECTION AND ANALYSIS Data were independently extracted by two reviewers. Relative treatment effects were estimated using network meta-analysis (NMA). MAIN RESULTS Of 12 632 citations searched, 21 RCTs were included. Comparing with usual care, "PFMT combine with perineal massage" and PFMT alone showed more superiority in intact perineum (RR = 5.37, 95% CI: 3.79 to 7.60, moderate certainty; RR = 2.58, 95% CI 1.34-4.97, moderate certainty, respectively), episiotomy (RR = 0.26, 95% CI 0.14-0.49, very low certainty; RR = 0.63, 95% CI 0.45-0.90, very low certainty, respectively), and OASIS (RR = 0.35, 95% CI 0.16-0.78, moderate certainty; RR = 0.49, 95% CI 0.28-0.85, high certainty, respectively). "PFMT combine with perineal massage" showed superiority in reducing perineal tear (RR = 0.41, 95% CI 0.20-0.85, moderate certainty). CONCLUSIONS In view of the results, antenatal "PFMT combine with perineal massage" and PFMT were effective strategies for the prevention of perineal trauma.

Abstract
BRIEF SUMMARY Maternal somatic birth trauma due to vaginal delivery is more common than generally assumed and an important cause of future morbidity. Maternal birth trauma may involve both psychological and somatic morbidity, some of it long-term and permanent. Somatic birth trauma is now understood to encompass not just episiotomy, perineal tears and obstetric anal sphincter injuries (OASI), but also trauma to the levator ani muscle, termed 'avulsion'. This review will focus on recent developments in the imaging diagnosis of maternal birth trauma, discuss the most important risk factors and strategies for primary and secondary prevention. Translabial and exo-anal ultrasound allow the assessment of maternal birth trauma in routine clinical practice and enable the use of levator avulsion and anal sphincter trauma as key performance indicators of maternity services. This is likely to lead to a greater awareness of maternal birth trauma amongst maternity caregivers and improved outcomes for patients, not the least due to an increasing emphasis on patient autonomy and informed consent in antenatal and intrapartum care.

Abstract
AIM To investigate the effectiveness of interventions to prevent the occurrence of perineal trauma in parturients. METHODS A bibliographic search was carried out in Cochrane Library, MEDLINE via PUBMED, LILACS via Virtual Health Library (VHL), Embase, Scopus, CINAHL, Scielo, Web of Science, and PEDro databases. Randomized clinical trials evaluating the effects of any intervention to prevent perineal trauma during pregnancy and/or childbirth were included. There were no temporal or language restrictions. The risk of bias assessment was performed using the Revised Cochrane Risk-of-bias Tool for Randomized Trials. RESULTS Fifty studies, with a total of 17,221 participants, were included in this meta-analysis. No intervention during childbirth was effective for the prevention of perineal trauma (RR = 1.07, 95% CI [0.98.1.18], p < 0.01, I2 = 83%) when compared to no intervention. However, a lower risk of perineal laceration was verified with techniques performed during pregnancy, when compared to no intervention (RR = 0.81, 95% CI [0.71, 0.93], p = 0.05, I2 = 47%). Among them, highlight the effects of perineal massage in preventing lacerations (RR = 0.69, 95% CI [0.54, 0.87], p < 0.01) when compared to no intervention. CONCLUSIONS The techniques performed during pregnancy, especially perineal massage, are associated with a lower risk of perineal laceration.

Abstract
OBJECTIVE We aimed to describe a method for identifying and evaluating perineal scars using translabial pelvic floor ultrasound. We hypothesized that translabial ultrasound can identify a perineal scar and can differentiate episiotomies from spontaneous tears. METHODS This pilot study is a secondary analysis of data obtained in the Epi-No® trial. Perineal integrity was assessed using volumes acquired on pelvic floor muscle contraction according to the method previously described for anal sphincter imaging. A scar was diagnosed if a hypoechoic distortion in the perineum was noted. We postulated that an episiotomy would result in a linear scar visible on four dimensional translabial ultrasound whereas nonlinear scars were considered the result of spontaneous perineal tear of grade 2 or higher. The results of this assessment were compared with data retrieved from electronic medical records. RESULTS A scar was identified in 79/120 women (66%): 42 (35%) linear and 37 (31%) nonlinear. Sonographic and clinical diagnosis agreed on the presence or absence of perineal trauma in 66%. Agreement for the type of laceration was 50%. CONCLUSION In this retrospective pilot study, a blinded assessment of translabial ultrasound volume data showed agreement between clinical data and sonographic assessment of perineal integrity in 66% and of type of laceration in 50%. More work is needed to optimize the method in assessment of perineal scars to improve its performance before it can be used in clinical audit and research.

Abstract
Abstract
Purpose This guideline provides recommendations for the diagnosis, treatment and follow-up care of 3rd and 4th degree perineal tears which occur during vaginal birth. The aim is to
improve the management of 3rd and 4th degree perineal tears and reduce the immediate and long-term damage. The guideline is intended for midwives, obstetricians and physicians involved in
caring for high-grade perineal tears.
Methods A selective search of the literature was carried out. Consensus about the recommendations and statements was achieved as part of a structured process during a consensus
conference with neutral moderation.
Recommendations After every vaginal birth, a careful inspection and/or palpation by the obstetrician and/or the midwife must be carried out to exclude a 3rd or 4th degree perineal
tear. Vaginal and anorectal palpation is essential to assess the extent of birth trauma. The surgical team must also include a specialist physician with the appropriate expertise (preferably
an obstetrician or a gynecologist or a specialist for coloproctology) who must be on call. In exceptional cases, treatment may also be delayed for up to 12 hours postpartum to ensure that a
specialist is available to treat the individual layers affected by trauma. As neither the end-to-end technique nor the overlapping technique have been found to offer better results for the
management of tears of the external anal sphincter, the surgeon must use the method with which he/she is most familiar. Creation of a bowel stoma during primary management of a perineal tear
is not indicated. Daily cleaning of the area under running water is recommended, particularly after bowel movements. Cleaning may be carried out either by rinsing or alternate cold and warm
water douches. Therapy should also include the postoperative use of laxatives over a period of at least 2 weeks. The patient must be informed about the impact of the injury on subsequent
births as well as the possibility of anal incontinence.

Abstract
The necessity of increasingly addressing aspects of pelvic floor protection, i.e., prevention of the most frequent female pelvic floor disorders, such as urinary incontinence, faecal incontinence and pelvic organ prolapse, is the result of the steadily improving understanding of the association of pregnancy and delivery with the prevalence of these disorders. About a quarter of all women experience one or more such symptoms during their life. Apart from age and weight, pregnancies and births play an important part. While initial discussion of pelvic floor protection often focused very rapidly on the mode of delivery and elective caesarean section as a possible protective intervention, it has become apparent in the last few decades how varied and wide-ranging the options are that can be used to protect against pelvic floor disorders. The mode of delivery as such is "only" one element among numerous other considerations and has diminished markedly in importance. Interprofessionality and interdisciplinarity undoubtedly represent an important development as resulting recommendations must always be incorporated in an overall context that considers mother and child at the same time. Considering the pelvic floor only certainly does not make sense. This review article will analyze in greater detail important pre-, intra- and postpartum aspects that in their entirety can provide insight into the various aspects of pelvic floor protection. The authors regard the following article as an additional basis for discussion on achieving a sustained reduction in the incidence and prevalence of female pelvic floor disorders.

Are Perineal Massage and Instrument-Assisted Perineal Stretching With Short Protocol Effective for Increasing Pelvic Floor Muscle Extensibility? A Randomized Controlled Trial. Phys Ther 2022; 102:6544340. [PMID: 35258595 DOI: 10.1093/ptj/pzab305] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 08/11/2021] [Accepted: 11/21/2021] [Indexed: 11/12/2022]
Abstract
OBJECTIVE The purpose of this study was to compare (1) the effects of the instrument-assisted perineal stretching technique with different application protocols in combination with perineal massage and (2) the effects of the isolated techniques on the extensibility and strength of the pelvic floor muscles (PFMs). METHODS A randomized controlled clinical trial with parallel randomization, assessor blinding, and concealed allocation was conducted in the Campus Physical Education at the Federal University of Uberlândia in Brazil. Ninety-six pregnant women (18-40 years of age) were allocated into 4 groups: perineal massage (PnM) group (PnM protocol for 10 minutes); instrument-assisted perineal stretching with a long static protocol for 15 minutes [IStrLS group]); PnM + IStrLS group (both techniques applied in the 2 previous groups); and PnM + IStrSR group (the same techniques as used in the PnM + IStrLS group but with a short repeated protocol; 4 sets lasting 30 seconds each). Eight interventions were performed in all 4 groups twice weekly (beginning at the 34th gestational week). The primary outcome was PFM extensibility, assessed using vaginal dilator circumference, and the secondary outcome was PFM strength, assessed using vaginal manometry. RESULTS For the PFM extensibility variable, a significant main effect of time (F2,88 = 87.951) and group (F3,88 = 7.193) was found. Tukey post hoc test results showed that the PnM + IStrSR group presented greater extensibility than the PnM and IStrLS groups. The PnM group showed increased PFM strength after 8 sessions compared with the other groups. CONCLUSIONS Women who were pregnant and received the combination of perineal massage and instrument-assisted perineal stretching with short repeated application had a greater increase in PFM extensibility than perineal massage and instrument-assisted perineal stretching alone. IMPACT The combination of perineal massage and instrument-assisted perineal stretching techniques with a short, repeated protocol led to better PFM extensibility results than the application of the techniques alone in women who were pregnant. LAY SUMMARY Pregnant women can benefit from intervention using the combination of perineal massage and instrument-assisted perineal stretching techniques with a short, repeated protocol.

On the management of maternal pushing during the second stage of labor: a biomechanical study considering passive tissue fatigue damage accumulation. Am J Obstet Gynecol 2022; 227:267.e1-267.e20. [PMID: 35101408 PMCID: PMC9308631 DOI: 10.1016/j.ajog.2022.01.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 01/07/2022] [Accepted: 01/14/2022] [Indexed: 12/27/2022]
Abstract
BACKGROUND During the second stage of labor, the maternal pelvic floor muscles undergo repetitive stretch loading as uterine contractions and strenuous maternal pushes combined to expel the fetus, and it is not uncommon that these muscles sustain a partial or complete rupture. It has recently been demonstrated that soft tissues, including the anterior cruciate ligament and connective tissue in sheep pelvic floor muscle, can accumulate damage under repetitive physiological (submaximal) loads. It is well known to material scientists that this damage accumulation can not only decrease tissue resistance to stretch but also result in a partial or complete structural failure. Thus, we wondered whether certain maternal pushing patterns (in terms of frequency and duration of each push) could increase the risk of excessive damage accumulation in the pelvic floor tissue, thereby inadvertently contributing to the development of pelvic floor muscle injury. OBJECTIVE This study aimed to determine which labor management practices (spontaneous vs directed pushing) are less prone to accumulate damage in the pelvic floor muscles during the second stage of labor and find the optimum approach in terms of minimizing the risk of pelvic floor muscle injury. STUDY DESIGN We developed a biomechanical model for the expulsive phase of the second stage of labor that includes the ability to measure the damage accumulation because of repetitive physiological submaximal loads. We performed 4 simulations of the second stage of labor, reflecting a directed pushing technique and 3 alternatives for spontaneous pushing. RESULTS The finite element model predicted that the origin of the pubovisceral muscle accumulates the most damage and so it is the most likely place for a tear to develop. This result was independent of the pushing pattern. Performing 3 maternal pushes per contraction, with each push lasting 5 seconds, caused less damage and seemed the best approach. The directed pushing technique (3 pushes per contraction, with each push lasting 10 seconds) did not reduce the duration of the second stage of labor and caused higher damage accumulation. CONCLUSION The frequency and duration of the maternal pushes influenced the damage accumulation in the passive tissues of the pelvic floor muscles, indicating that it can influence the prevalence of pelvic floor muscle injuries. Our results suggested that the maternal pushes should not last longer than 5 seconds and that the duration of active pushing is a better measurement than the total duration of the second stage of labor. Hopefully, this research will help to shed new light on the best practices needed to improve the experience of labor for women.

Abstract
BACKGROUND Informed consent in obstetrics should involve full disclosure of risks, benefits and alternative interventions. However, we have found no evidence of a formal informed consent process before an attempt at vaginal delivery in published policy or practice. The idea of informed consent in vaginal birth has attracted controversy and has been the subject of some debate. AIM To explore the perspectives and experiences of informed consent and birth preparedness/complication readiness for birthing women in a high resource setting. MATERIALS AND METHODS Qualitative study using semi-structured interviews to examine experiences and perspectives of women following birth. RESULTS Forty telephone interviews were concluded. Eight statement categories were identified: (i) no issues of consent, (ii) absent/inadequate informed consent, (iii) adequate birth preparedness/complication readiness, (iv) inadequate birth preparedness/complication readiness, (v) desire to forfeit decision making to a trusted and accountable health professional, (vi) belief that informed consent is not realistic in birth under some circumstances, (vii) negative feelings related to birth and (viii) poor postnatal follow-up. CONCLUSIONS When complications arose during birth, 20% of participants felt that informed consent was absent/inadequate, 25% of participants suggested policy change in favour of a formal informed consent process and 55% of participants suggested policy change in favour of increased birth preparedness/complication readiness. Our study suggests that informed consent for vaginal birth and formal birth preparedness/complication readiness should form part of routine antenatal care. Women's preferences for decision-making and informed consent should be established before birth.

Abstract
BACKGROUND Pelvic floor muscle training (PFMT) is reportedly able to reduce risk factors for perineal trauma. However, the effects of these exercises on perineal injuries are unclear. OBJECTIVE To investigate the effectiveness of PFMT in the prevention of perineal laceration. SEARCH STRATEGY Searches were conducted in PubMed/Medline, LILACS, Scopus, Cochrane Library, Web of Science, and CINAHL. For search strategies, we combined the terms PFMT, tear, laceration, perineum, and delivery. SELECTION CRITERIA We included randomized controlled trials that evaluated the effectiveness of PFMT for the prevention of perineal laceration during vaginal delivery. There were no period or language limitations. DATA COLLECTION AND ANALYSIS We conducted data extraction and synthesis. We performed a quality appraisal, a qualitative synthesis, and for meta-analysis we used the Software R. MAIN RESULTS Nine studies were included. In most studies, PFMT was performed daily, with a wide range of the number of contractions and sustainability. Prevalence of perineal laceration had a wide range and information on laceration degree was limited. Meta-analysis showed that PFMT was not effective to prevent perineal laceration. CONCLUSION Pelvic floor muscle training does not prevent perineal laceration. Further studies are needed to investigate different protocols and interventions.

Abstract
INTRODUCTION AND HYPOTHESIS The term 'maternal birth trauma' has undergone substantial changes in meaning over the last 2 decades. Leaving aside psychological morbidity, somatic trauma is now understood to encompass not just episiotomy, perineal tears and obstetric anal sphincter injuries (OASI), but also trauma to the levator ani muscle. This review covers diagnosis of maternal birth trauma by translabial ultrasound imaging. METHODS Narrative review. RESULTS Tomographic imaging of pelvic structures with the help of 4D ultrasound, used since 2007, has allowed international standardization and seems to be highly reproducible and valid for the diagnosis of OASI and levator avulsion. CONCLUSIONS Translabial and exo-anal ultrasound allows the assessment of maternal birth trauma in routine clinical practice and the utilization of avulsion and sphincter trauma as key performance indicators of maternity services. It is hoped that this will lead to a greater awareness of maternal birth trauma among maternity caregivers and improved outcomes for patients, both in the short term and in the decades to come.

Risk of obstetric anal sphincter injuries (OASIS) and anal incontinence: A meta-analysis. Eur J Obstet Gynecol Reprod Biol 2020; 252:303-312. [PMID: 32653603 DOI: 10.1016/j.ejogrb.2020.06.048] [Citation(s) in RCA: 41] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Revised: 06/19/2020] [Accepted: 06/22/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND Obstetric anal sphincter injuries (OASIS) are the commonest cause of anal incontinence in women of reproductive age. We determined the risk of anal sphincter defects diagnosed by ultrasound, and the risk of anal incontinence in (i) all women who deliver vaginally, (ii) in women without clinical suspicion of OASIS, and (iii) after primary repair of sphincter injury, by systematic review. METHODS We searched major databases until June 2018, without language restrictions. Random effects meta-analysis was used to obtain pooled estimates of ultrasound diagnosed OASIS and risk of anal incontinence symptoms at various time points after delivery, and of persistent sphincter defects after primary repair. We reported the association between ultrasound diagnosed OASIS and anal incontinence symptoms using relative risk (RR) with 95 % CI. RESULTS We included 103 studies involving 16,110 women. Of all women who delivered vaginally, OASIS were diagnosed on ultrasound in 26 % (95 %CI, 21-30, I2 = 91 %), and 19 % experienced anal incontinence (95 %CI, 14-25, I2 = 92 %). In women without clinical suspicion of OASIS (n = 3688), sphincter defects were observed in 13 % (10-17, I2 = 89 %) and anal incontinence experienced by 14 % (95 % CI: 6-24, I2 = 95 %). Following primary repair of OASIS, 55 % (46-63, I2 = 98 %) of 7549 women had persistent sphincter defect with 38 % experiencing anal incontinence (33-43, I2 = 92 %). There was a significant association between ultrasound diagnosed OASIS and anal incontinence (RR 3.74, 2.17-6.45, I2 = 98 %). INTERPRETATION Women and clinicians should be aware of the high risk for sphincter defects following vaginal delivery even when clinically unsuspected. This underlines the need of careful and systematic perineal assessment after birth to mitigate the risk of missing OASIS. We also noted a high rate of persistent defects and symptoms following primary repair of OASIS. This dictates the need for provision of robust training for clinicians to achieve proficiency and sustain competency in repairing OASIS.

Abstract
INTRODUCTION AND HYPOTHESIS An increase in vaginal delivery with forceps may increase rates of pelvic floor trauma. This study was designed to predict trauma rates resulting from policies preferencing forceps. METHODS This is an observational cohort study utilizing data from 660 primiparae enrolled in an RCT in two tertiary obstetric units in Sydney, Australia. Participants were assessed clinically and with 4D translabial ultrasound in the late third trimester and again at 3-6 months postpartum. Incidence of trauma associated with mode of delivery was adjusted to reflect change associated with a conversion of vacuum to forceps delivery. Primary outcome measures were third-/fourth-degree tear, levator avulsion (LA) and external anal sphincter (EAS) trauma diagnosed sonographically. RESULTS Five hundred four women were seen at a mean of 5.1 (2.3-24.3) months postpartum. After exclusion of 21 because of missing data, 483 women were analysed: 112 (23%) had a CS, 268 (55%) a normal vaginal delivery (NVD), 69 (14%) a vacuum (VD) and 34 (7%) a forceps (FD). One hundred fifty-two women had EAS trauma and/or LA; 17 sustained both. After VD, 32/69 (46%) women suffered LA and/or EAS trauma; after FD, it was 33/34 (97%). Converting VD to FD was estimated to result in an increase in trauma from 152/483 (31%) to 187/483 (39%). A formula can be generated based on local obstetric and ultrasound data to estimate trauma incidence. CONCLUSIONS A change in obstetric practice resulting in the conversion of primary VD to primary FD would be expected to substantially increase the likelihood of pelvic floor trauma.

Abstract
INTRODUCTION AND HYPOTHESIS The current data on the effectiveness of antenatal pelvic floor muscle exercises (PFME) on childbirth outcomes are limited. Therefore, in this study the effect of antenatal PFMEs on labour and birth outcomes was assessed by undertaking a meta-analysis. METHODS Databases were systematically searched from 1988 until June 2019. Randomised controlled trials (RCTs) and quasi-experimental studies were included. The methodological quality of studies was assessed using Cochrane Collaboration tools. The outcomes of interest were: duration of first and second stage of labour, episiotomy and perineal outcomes, mode of birth (spontaneous vaginal birth, instrumental birth and caesarean section) and fetal presentation. The mean difference (MD) and risk ratio RR) with the corresponding 95% confidence intervals (CIs) were calculated to assess the association between PFME and the childbirth outcomes. RESULTS A total of 16 articles were included (n = 2,829 women). PFME shortened the duration of the second stage of labour (MD: -20.90, 95%, CI: -31.82 to -9.97, I2: 0%, p = 0.0002) and for primigravid women (MD: -21.02, 95% CI: -32.10 to -9.94, I2: 0%, p = 0.0002). PFME also reduced severe perineal lacerations (RR 0.57, 95% CI: 0.38 to 0.84, I2: 30%, p = 0.005). No significant difference was seen in normal vaginal birth, caesarean section, instrumental birth and episiotomy rate. Most of the studies carried a moderate to high risk of bias. CONCLUSION Antenatal PFME may be effective at shortening the second stage of labour and reducing severe perineal trauma. These findings need to be interpreted considering the included studies' risk of bias. More high-quality RCTs are needed.

Abstract
BACKGROUND About one-third of women have urinary incontinence (UI) and up to one-tenth have faecal incontinence (FI) after childbirth. Pelvic floor muscle training (PFMT) is commonly recommended during pregnancy and after birth for both preventing and treating incontinence. This is an update of a Cochrane Review previously published in 2017. OBJECTIVES To assess the effects of PFMT for preventing or treating urinary and faecal incontinence in pregnant or postnatal women, and summarise the principal findings of relevant economic evaluations. SEARCH METHODS We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, CINAHL, ClinicalTrials.gov, WHO ICTRP, and handsearched journals and conference proceedings (searched 7 August 2019), and the reference lists of retrieved studies. SELECTION CRITERIA We included randomised or quasi-randomised trials in which one arm included PFMT. Another arm was no PFMT, usual antenatal or postnatal care, another control condition, or an alternative PFMT intervention. Populations included women who, at randomisation, were continent (PFMT for prevention) or incontinent (PFMT for treatment), and a mixed population of women who were one or the other (PFMT for prevention or treatment). DATA COLLECTION AND ANALYSIS We independently assessed trials for inclusion and risk of bias. We extracted data and assessed the quality of evidence using GRADE. MAIN RESULTS We included 46 trials involving 10,832 women from 21 countries. Overall, trials were small to moderately-sized. The PFMT programmes and control conditions varied considerably and were often poorly described. Many trials were at moderate to high risk of bias. Two participants in a study of 43 pregnant women performing PFMT for prevention of incontinence withdrew due to pelvic floor pain. No other trials reported any adverse effects of PFMT. Prevention of UI: compared with usual care, continent pregnant women performing antenatal PFMT probably have a lower risk of reporting UI in late pregnancy (62% less; risk ratio (RR) 0.38, 95% confidence interval (CI) 0.20 to 0.72; 6 trials, 624 women; moderate-quality evidence). Antenatal PFMT slightly decreased the risk of UI in the mid-postnatal period (more than three to six months' postpartum) (29% less; RR 0.71, 95% CI 0.54 to 0.95; 5 trials, 673 women; high-quality evidence). There was insufficient information available for the late postnatal period (more than six to 12 months) to determine effects at this time point (RR 1.20, 95% CI 0.65 to 2.21; 1 trial, 44 women; low-quality evidence). Treatment of UI: compared with usual care, there is no evidence that antenatal PFMT in incontinent women decreases incontinence in late pregnancy (very low-quality evidence), or in the mid-(RR 0.94, 95% CI 0.70 to 1.24; 1 trial, 187 women; low-quality evidence), or late postnatal periods (very low-quality evidence). Similarly, in postnatal women with persistent UI, there is no evidence that PFMT results in a difference in UI at more than six to 12 months postpartum (RR 0.55, 95% CI 0.29 to 1.07; 3 trials; 696 women; low-quality evidence). Mixed prevention and treatment approach to UI: antenatal PFMT in women with or without UI probably decreases UI risk in late pregnancy (22% less; RR 0.78, 95% CI 0.64 to 0.94; 11 trials, 3307 women; moderate-quality evidence), and may reduce the risk slightly in the mid-postnatal period (RR 0.73, 95% CI 0.55 to 0.97; 5 trials, 1921 women; low-quality evidence). There was no evidence that antenatal PFMT reduces the risk of UI at late postpartum (RR 0.85, 95% CI 0.63 to 1.14; 2 trials, 244 women; moderate-quality evidence). For PFMT started after delivery, there was uncertainty about the effect on UI risk in the late postnatal period (RR 0.88, 95% CI 0.71 to 1.09; 3 trials, 826 women; moderate-quality evidence). Faecal incontinence: eight trials reported FI outcomes. In postnatal women with persistent FI, it was uncertain whether PFMT reduced incontinence in the late postnatal period compared to usual care (very low-quality evidence). In women with or without FI, there was no evidence that antenatal PFMT led to a difference in the prevalence of FI in late pregnancy (RR 0.64, 95% CI 0.36 to 1.14; 3 trials, 910 women; moderate-quality evidence). Similarly, for postnatal PFMT in a mixed population, there was no evidence that PFMT reduces the risk of FI in the late postnatal period (RR 0.73, 95% CI 0.13 to 4.21; 1 trial, 107 women, low-quality evidence). There was little evidence about effects on UI or FI beyond 12 months' postpartum. There were few incontinence-specific quality of life data and little consensus on how to measure it. AUTHORS' CONCLUSIONS This review provides evidence that early, structured PFMT in early pregnancy for continent women may prevent the onset of UI in late pregnancy and postpartum. Population approaches (recruiting antenatal women regardless of continence status) may have a smaller effect on UI, although the reasons for this are unclear. A population-based approach for delivering postnatal PFMT is not likely to reduce UI. Uncertainty surrounds the effects of PFMT as a treatment for UI in antenatal and postnatal women, which contrasts with the more established effectiveness in mid-life women. It is possible that the effects of PFMT might be greater with targeted rather than mixed prevention and treatment approaches, and in certain groups of women. Hypothetically, for instance, women with a high body mass index (BMI) are at risk of UI. Such uncertainties require further testing and data on duration of effect are also needed. The physiological and behavioural aspects of exercise programmes must be described for both PFMT and control groups, and how much PFMT women in both groups do, to increase understanding of what works and for whom. Few data exist on FI and it is important that this is included in any future trials. It is essential that future trials use valid measures of incontinence-specific quality of life for both urinary and faecal incontinence. In addition to further clinical studies, economic evaluations assessing the cost-effectiveness of different management strategies for FI and UI are needed.

Abstract
Objective: To determine the test-retest reliability of the pelvic floor distensibility evaluation with Epi-no® device.Methods: Prospective, blinded observational study with 32 women pregnant from 35 gestational weeks. An Epi-no® balloon was inflated within the pregnant woman's vagina and the maximum circumference achieved was measured using a standard metric measuring tape. Measurements were performed twice in a day by two physiotherapists in a randomized order. Intraobserver reproducibility was obtained with another evaluation 7-14 d after the initial examination. The intraclass correlation coefficient (ICC) was used to determine the intra and interrater reliability and the respective 95% confidence intervals with an alpha level of 0.05.Results: From a total of 32 included pregnant women, 28 were analyzed; they were 29.3 (±5.97) years old, were at 37 (±1.3) weeks' gestation and presented a mean Epi-no® circumference of 20.4 (±2.4) cm. Regarding the intraobserver analysis, examiner 1 observed a maximum circumference of 20.6 (±2.6) cm in the first evaluation and 20.2 (±2.4) cm in the second evaluation, with good reliability (ICC = 0.85). Examiner 2 observed 19.7 (±2.4) cm in the first evaluation and 21.0 (±2.0) cm in the second one, with moderate reliability (ICC = 0.58). Regarding the interobserver analysis, there was good reliability on two evaluation days, with an ICC of 0.76 and 0.82, respectively.Conclusions: Epi-no® device is a reliable device for physiotherapists to measure pelvic floor distention during pregnancy.

Abstract
In the era of new molecular, epigenetic and proteomic discoveries, birth canal injuries seem like outdated discussion. A vast increase in the incidence of obstetric anal sphincter injuries (OASIS) has been recorded in the last two decades despite advantages in modern medicine and new obstetric methods. This increase might be attributed to the new classification of perineal injury but also to the new imaging methods, including endoanal sonography, which earlier identifies injuries that previously were considered to be occult and actually underwent unrecognized, and which should have been recognized immediately postpartum. OASIS are third and fourth degree perineal injuries that occur during delivery. The reported incidence of OASIS varies from 0.1% to 10.9%. It is well known that third and fourth degree perineal injuries occur more often in primiparae, and in cases of macrosomic newborn, dorsoposterior position of fetal head and shoulder dystocia. The protective role of episiotomy is controversial. Birth canal injury during delivery can happen to any parturient woman. It is important for obstetricians to have this in mind at every delivery. Repercussions of OASIS are serious and can persist for life. They include emotional, psychological, social, physical and sexual disturbances. Therefore, it is very important to recognize the risk factors, diagnose the injury on time and treat it properly by a multidisciplinary team. Accordingly, it can be concluded that the increased incidence of OASIS is a result of better recognition of the risk factors, reduced rates of unrecognized sphincter injuries, adoption of the new classification and better postpartum imagining methods for detection of occult injuries.

Abstract
OBJECTIVES This study aimed to ascertain the association between levator avulsion and pelvic organ prolapse (POP). METHODS This was a cross-sectional study involving 195 women enrolled in a longitudinal cohort study and seen 20 years after an index birth. All had a standardized patient-administered questionnaire, the International Continence Society Pelvic Organ Prolapse Quantification assessment and 4D translabial ultrasound. Main outcome measures were objective POP clinically and on translabial ultrasound. Postimaging assessment of levator integrity and sonographically determined pelvic organ descent was done blinded against other data. RESULTS Of 195 women who were seen a mean of 23 (range, 19.4-46.2) years after their first birth, one declined ultrasound assessment and was excluded, leaving 194. Mean age was 50.2 (range 36.9-66.5) years with a mean body mass index (BMI) of 27.6 (range, 18.3-54.3) kg/m2 . Median parity was 3 (range 1-14). Ninety-one percent (n = 176) had delivered vaginally. Eighteen percent (n = 34) were symptomatic of prolapse. Clinically, 36% (n = 69) had significant POP. Levator avulsion was diagnosed in 16% (n = 31). Mean levator avulsion defect score was 2.2 (range, 0-12). On univariate analysis, levator avulsion and levator avulsion defect score were associated with clinically and sonographically significant POP, that is, odds ratio 2.6 (1.2-5.7), P = .01; and odds ratio 3.3 (1.4-7.7); P = .003, respectively; Ba (P < .001); bladder (P < .001); uterine (P < .001) and rectal ampulla (P = .009) descent, but not POP symptoms, C, and Bp. Multivariate analysis controlling for potential confounders confirmed our findings. CONCLUSIONS Levator avulsion is associated with female pelvic organ prolapse, especially of the anterior and central compartments. This association may become stronger with aging.

Abstract
OBJECTIVE Several interventions during pregnancy have been described that might prevent the risk of postnatal perineal injury or dysfunction; these include prenatal perineal massage, use of the Epi-No device, and pelvic floor muscle training exercises. Our objective was to evaluate the effectiveness of these different interventions during pregnancy. METHODS A systematic review of the literature was conducted on PubMed, including articles in French and English published before May 2018, to evaluate the effectiveness of these different interventions on perineal protection in the post-partum period. RESULTS Perineal massage during pregnancy diminishes the episiotomy rate (LE1) as well as post-partum perineal pain and flatus (LE2). It does not reduce the rate of either OASIS (LE1) or post-partum urinary incontinence (LE2). The Epi-No device does not provide benefits for perineal protection (LE1). Prenatal pelvic floor muscle training exercises do not reduce the risk of perineal lacerations (LE2); they reduce the prevalence of post-partum urinary incontinence at 3 to 6 months but not at 12 months post-partum (LE2). CONCLUSION Perineal massage during pregnancy must be encouraged among women who want it (Grade B). The use of the Epi-No device during pregnancy is not recommended for the prevention of OASIS (grade B). Pelvic floor muscle training during pregnancy is not recommended for the prevention of OASIS (grade B); moreover, its absence of effect in the medium term does not allow us to recommend it for urinary incontinence (professional consensus).

Abstract
INTRODUCTION AND HYPOTHESIS Perineal preparation techniques for childbirth have been used with the aim of reducing perineal tears during the expulsive phase of labor. However, no studies were found to investigate the effects of instrument-assisted stretching versus perineal massage on pelvic floor muscle (PFM) variables. Therefore, the aim of this study was to evaluate the effect of instrument-assisted stretching versus perineal massage on the extensibility and strength of the PFMs. METHODS Primiparous women were randomized to the instrument-assisted stretching (IStr) group (n = 13) and perineal massage (PnM) group (n = 14). The groups participated in eight sessions, twice weekly, beginning at the 34th gestational week. The IStr group underwent the intervention for 15 min using EPI-NO®. The PnM group underwent a perineal massage protocol for 10 min. Each woman was evaluated by a blinded physiotherapist before, after four and after eight sessions for primary (PFM extensibility using the EPI-NO® circumference) and secondary (PFM strength using a manometer) outcomes. Covariate analysis (ANCOVA) was used to compare the groups using the baseline values as a covariate. RESULTS Both groups showed an increase in PFM extensibility compared with the evaluations before and after four and eight sessions (PnM group from 17.6 ± 1.8 to 20.2 ± 1.9 cm; IStr group from 19.9 ± 1.6 to 22.9 ± 1.6 cm;p < 0.001). There was no difference between groups. Regarding muscle strength, no statistical differences were observed between evaluations or between groups. CONCLUSIONS Instrument-assisted stretching and perineal massage increase extensibility and do not alter the strength of PFMs in pregnant women.

Abstract
BACKGROUND Pelvic floor interventions during pregnancy could reduce the impact of pregnancy and delivery on the pelvic floor. OBJECTIVE To determine the effects of pelvic floor interventions during pregnancy on childbirth-related and pelvic floor parameters. SEARCH STRATEGY PubMed, Embase, and LILACS were searched for reports published during between 1990 and 2016 in English, Spanish, or Portuguese. The search terms were "pregnancy," "pelvic floor muscle training," and related terms. SELECTION CRITERIA Randomized controlled trials with healthy pregnant women were included. DATA COLLECTION AND ANALYSIS Baseline and outcome data (childbirth-related parameters, pelvic floor symptoms) were compared for three interventions: EPI-NO (Tecsana, Munich, Germany) perineal dilator, pelvic floor muscle training, and perineal massage. MAIN RESULTS A total of 22 trials were included. Two of three papers assessing EPI-NO showed no benefit. The largest study investigating pelvic floor muscle training reported a significant reduction in the duration of the second stage of labor (P<0.01), and this intervention also reduced the incidence of urinary incontinence (evaluated in 10 trials). Two of six trials investigating perineal massage reported that a lower rate of perineal pain was associated with this intervention. CONCLUSION Pelvic floor muscle training and perineal massage improved childbirth-related parameters and pelvic floor symptoms, whereas EPI-NO showed no benefit.

Abstract
BACKGROUND Trauma to the perineum, levator ani complex, and anal sphincter is common during vaginal childbirth, but often clinically underdiagnosed, and many women are unaware of the potential for long-term damage. OBJECTIVE In this study we use transperineal ultrasound to identify how many women will achieve a normal vaginal delivery without substantial damage to the levator ani or anal sphincter muscles, and to create a model to predict patient characteristics associated with successful atraumatic normal vaginal delivery. STUDY DESIGN This is a retrospective, secondary analysis of data sets gathered in the context of an interventional perinatal imaging study. A total of 660 primiparas, carrying an uncomplicated singleton pregnancy, underwent an antepartum and postpartum interview, vaginal exam (Pelvic Organ Prolapse Quantification), and 4-dimensional translabial ultrasound. Ultrasound data were analyzed for levator trauma and/or overdistention and residual sphincter defects. Postprocessing analysis of ultrasound volumes was performed blinded against clinical data and analyzed against obstetric data retrieved from the local maternity database. Levator avulsion was diagnosed if the muscle insertion at the inferior pubic ramus at the plane of minimal hiatal dimensions and within 5 mm above this plane on tomographic ultrasound imaging was abnormal, ie the muscle was disconnected from the inferior pubic ramus. Hiatal overdistensibility (microtrauma) was diagnosed if there was a peripartum increase in hiatal area on Valsalva by >20% with the resultant area ≥25 cm2. A sphincter defect was diagnosed if a gap of >30 degrees was seen in ≥4 of 6 tomographic ultrasound imaging slices bracketing the external anal sphincter. Two models were tested: a first model that defines severe pelvic floor trauma as either obstetric anal sphincter injury or levator avulsion, and a second, more conservative model, that also included microtrauma. RESULTS A total of 504/660 women (76%) returned for postpartum follow-up as described previously. In all, 21 patients were excluded due to inadequate data or intercurrent pregnancy, leaving 483 women for analysis. Model 1 defined nontraumatic vaginal delivery as excluding operative delivery, obstetric anal sphincter injuries, and sonographic evidence of levator avulsion or residual sphincter defect. Model 2 also excluded microtrauma. Of 483 women, 112 (23%) had a cesarean delivery, 103 (21%) had an operative vaginal delivery, and 17 (4%) had a third-/fourth-degree tear, leaving 251 women who could be said to have had a normal vaginal delivery. On ultrasound, in model 1, 27 women (6%) had an avulsion and 31 (6%) had a residual defect, leaving 193/483 (40%) who met the criteria for atraumatic normal vaginal delivery. In model 2, an additional 33 women (7%) had microtrauma, leaving only 160/483 (33%) women who met the criteria for atraumatic normal vaginal delivery. On multivariate analysis, younger age and earlier gestation at time of delivery remained highly significant as predictors of atraumatic normal vaginal delivery in both models, with increased hiatal area on Valsalva also significant in model 2 (all P ≤ .035). CONCLUSION The prevalence of significant pelvic floor trauma after vaginal child birth is much higher than generally assumed. Rates of obstetric anal sphincter injury are often underestimated and levator avulsion is not included as a consequence of vaginal birth in most obstetric text books. In this study less than half (33-40%) of primiparous women achieved an atraumatic normal vaginal delivery.

Abstract
Vaginal birth may result in damage to the levator ani muscle (LAM) with subsequent pelvic floor dysfunction and there may be accompanying psychological problems. This study examines associations between these somatic injuries and psychological symptoms. A qualitative study using semi-structured interviews to examine the experiences of primiparous women (n = 40) with known LAM trauma was undertaken. Participants were identified from a population of 504 women retrospectively assessed by a perinatal imaging study at two obstetric units in Sydney, Australia. LAM avulsion was diagnosed by 3D/4D translabial ultrasound 3-6 months postpartum. The template consisted of open-ended questions. Main outcome measures were quality of information provided antenatally; intrapartum events; postpartum symptoms; and coping mechanisms. Thematic analysis of maternal experiences was employed to evaluate prevalence of themes. Ten statement categories were identified: (1) limited antenatal education (29/40); (2) no information provided on potential morbidities (36/40); (3) conflicting advice (35/40); (4) traumatized partners (21/40); (5) long-term sexual dysfunction/relationship issues (27/40); (6) no postnatal assessment of injuries (36/40); (7) multiple symptoms of pelvic floor dysfunction (35/40); (8) "putting up" with injuries (36/40); (9) symptoms of post-traumatic stress disorder (PTSD) (27/40); (10) dismissive staff responses (26/40). Women who sustain LAM damage after vaginal birth have reduced quality of life due to psychological and somatic morbidities. PTSD symptoms are common. Clinicians may be unaware of the severity of this damage. Women report they feel traumatized and abandoned because such morbidities were not discussed prior to birth or postpartum.

Abstract
INTRODUCTION AND HYPOTHESIS The objective was to assess the safety and feasibility of using a pelvic floor dilator during active labor to prevent injuries to the levator ani muscle (LAM) and perineum. METHODS In a prospective pilot study, a pelvic floor dilator using soft pads was introduced into the vaginal canal to gradually expand the vagina, in 30 nulliparous women and in 10 controls. The primary outcomes were adverse events related to the device. Secondary outcomes were perineal lacerations after delivery, sonographically defined levator ani injury, hiatal area dimensions, and anal sphincter disruption, all at 12-20 weeks postpartum, and maximum pelvic floor dilation, time to achieve maximum dilation, and device retention rate. RESULTS From October 2014 through November 2016, a total of 494 women were screened, and 61 consented to the study. Thirty women used the device and 27 returned for follow-up. No maternal or neonatal injuries were related to use of the dilator. The average maximum dilation of the vaginal canal was 7.4 cm (SD 0.7, range 5.5-8.0). Dilation time averaged 27 min (SD 13, range 5-60). Device insertion adjustment was needed in 13 out of 30 cases (43%). Similar rates of 3th-4th degree perineal lacerations were seen in both groups. Levator ani avulsion was diagnosed in 2 out of 27 (7%) in the device group and in 1 out of 9 (11%) in the control group (p = 0.2). The rate of partial injury in the device group was 2 out of 27 (7%) vs 2 out of 9 (22%) in the comparison group (p = 0.2). CONCLUSION The use of the pelvic floor dilator during active labor is feasible. No safety issues were identified.

Abstract
PURPOSE OF REVIEW There is increasing awareness of the importance of intrapartum events for future pelvic floor morbidity in women. In this review, we summarize recent evidence and potential consequences for clinical practice. RECENT FINDINGS Both epidemiological evidence and data from perinatal imaging studies have greatly improved our understanding of the link between childbirth and later morbidity. The main consequences of traumatic childbirth are pelvic organ prolapse (POP) and anal incontinence. In both instances the primary etiological pathways have been identified: levator trauma in the case of POP and anal sphincter tears in the case of anal incontinence. As most such trauma is occult, imaging is required for diagnosis. SUMMARY Childbirth-related major maternal trauma is much more common than generally assumed, and it is the primary etiological factor in POP and anal incontinence. Both sphincter and levator trauma can now be identified on imaging. This is crucial not only for clinical care and audit, but also for research. Postnatally diagnosed trauma can serve as intermediate outcome measure in intervention trials, opening up multiple opportunities for clinical research aimed at primary and secondary prevention.

Abstract
Since its introduction in the early 1990s, endoanal sonography has become the mainstay of morphologic assessment of the anal canal and sphincter, especially for obstetric anal sphincter trauma. Lack of availability of suitable systems and the invasive nature of the method have limited uptake and clinical utility. More recently, exoanal or transperineal/translabial tomographic imaging has been developed as a noninvasive alternative. This pictorial overview aims to introduce the reader to this new diagnostic modality and to demonstrate common findings in asymptomatic and symptomatic women.

Abstract
BACKGROUND About one-third of women have urinary incontinence and up to one-tenth have faecal incontinence after childbirth. Pelvic floor muscle training (PFMT) is commonly recommended during pregnancy and after birth for both prevention and treatment of incontinence.This is an update of a review previously published in 2012. OBJECTIVES To determine the effectiveness of pelvic floor muscle training (PFMT) in the prevention or treatment of urinary and faecal incontinence in pregnant or postnatal women. SEARCH METHODS We searched the Cochrane Incontinence Specialised Register (16 February 2017) and reference lists of retrieved studies. SELECTION CRITERIA Randomised or quasi-randomised trials in pregnant or postnatal women. One arm of the trial included PFMT. Another arm was no PFMT, usual antenatal or postnatal care, another control condition, or an alternative PFMT intervention. DATA COLLECTION AND ANALYSIS Review authors independently assessed trials for inclusion and risk of bias. We extracted data and checked them for accuracy. Populations included: women who were continent (PFMT for prevention), women who were incontinent (PFMT for treatment) at randomisation and a mixed population of women who were one or the other (PFMT for prevention or treatment). We assessed quality of evidence using the GRADE approach. MAIN RESULTS The review included 38 trials (17 of which were new for this update) involving 9892 women from 20 countries. Overall, trials were small to moderate sized, and the PFMT programmes and control conditions varied considerably and were often poorly described. Many trials were at moderate to high risk of bias. Other than two reports of pelvic floor pain, trials reported no harmful effects of PFMT.Prevention of urinary incontinence: compared with usual care, continent pregnant women performing antenatal PFMT may have had a lower risk of reporting urinary incontinence in late pregnancy (62% less; risk ratio (RR) for incontinence 0.38, 95% confidence interval (CI) 0.20 to 0.72; 6 trials, 624 women; low-quality evidence). Similarly, antenatal PFMT decreased the risk of urinary incontinence in the mid-postnatal period (more than three to six months' postpartum) (29% less; RR 0.71, 95% CI 0.54 to 0.95; 5 trials, 673 women; moderate-quality evidence). There was insufficient information available for the late (more than six to 12 months') postnatal period to determine effects at this time point.Treatment of urinary incontinence: it is uncertain whether antenatal PFMT in incontinent women decreases incontinence in late pregnancy compared to usual care (RR 0.70, 95% CI 0.44 to 1.13; 3 trials, 345 women; very low-quality evidence). This uncertainty extends into the mid- (RR 0.94, 95% CI 0.70 to 1.24; 1 trial, 187 women; very low-quality evidence) and late (RR 0.50, 95% CI 0.13 to 1.93; 2 trials, 869 women; very low-quality evidence) postnatal periods. In postnatal women with persistent urinary incontinence, it was unclear whether PFMT reduced urinary incontinence at more than six to 12 months' postpartum (RR 0.55, 95% CI 0.29 to 1.07; 3 trials; 696 women; very low-quality evidence).Mixed prevention and treatment approach to urinary incontinence: antenatal PFMT in women with or without urinary incontinence (mixed population) may decrease urinary incontinence risk in late pregnancy (26% less; RR 0.74, 95% CI 0.61 to 0.90; 9 trials, 3164 women; low-quality evidence) and the mid-postnatal period (RR 0.73, 95% CI 0.55 to 0.97; 5 trials, 1921 women; very low-quality evidence). It is uncertain if antenatal PFMT reduces urinary incontinence risk late postpartum (RR 0.85, 95% CI 0.63 to 1.14; 2 trials, 244 women; low-quality evidence). For PFMT begun after delivery, there was considerable uncertainty about the effect on urinary incontinence risk in the late postnatal period (RR 0.88, 95% CI 0.71 to 1.09; 3 trials, 826 women; very low-quality evidence).Faecal incontinence: six trials reported faecal incontinence outcomes. In postnatal women with persistent faecal incontinence, it was uncertain whether PFMT reduced incontinence in the late postnatal period compared to usual care (RR 0.68, 95% CI 0.24 to 1.94; 2 trials; 620 women; very low-quality evidence). In women with or without faecal incontinence (mixed population), antenatal PFMT led to little or no difference in the prevalence of faecal incontinence in late pregnancy (RR 0.61, 95% CI 0.30 to 1.25; 2 trials, 867 women; moderate-quality evidence). For postnatal PFMT in a mixed population, there was considerable uncertainty about the effect on faecal incontinence in the late postnatal period (RR 0.73, 95% CI 0.13 to 4.21; 1 trial, 107 women, very low-quality evidence).There was little evidence about effects on urinary or faecal incontinence beyond 12 months' postpartum. There were few incontinence-specific quality of life data and little consensus on how to measure it. We found no data on health economics outcomes. AUTHORS' CONCLUSIONS Targeting continent antenatal women early in pregnancy and offering a structured PFMT programme may prevent the onset of urinary incontinence in late pregnancy and postpartum. However, the cost-effectiveness of this is unknown. Population approaches (recruiting antenatal women regardless of continence status) may have a smaller effect on urinary incontinence, although the reasons for this are unclear. It is uncertain whether a population-based approach for delivering postnatal PFMT is effective in reducing urinary incontinence. Uncertainty surrounds the effects of PFMT as a treatment for urinary incontinence in antenatal and postnatal women, which contrasts with the more established effectiveness in mid-life women.It is possible that the effects of PFMT might be greater with targeted rather than mixed prevention and treatment approaches and in certain groups of women. Hypothetically, for instance, women with a high body mass index are at risk factor for urinary incontinence. Such uncertainties require further testing and data on duration of effect are also needed. The physiological and behavioural aspects of exercise programmes must be described for both PFMT and control groups and how much PFMT women in both groups do, to increase understanding of what works and for whom.Few data exist on faecal incontinence or costs and it is important that both are included in any future trials. It is essential that future trials use valid measures of incontinence-specific quality of life for both urinary and faecal incontinence.

Influence of a pelvic floor training programme to prevent perineal trauma: A quasi-randomised controlled trial. Midwifery 2017; 50:72-77. [PMID: 28391147 DOI: 10.1016/j.midw.2017.03.015] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2016] [Revised: 03/13/2017] [Accepted: 03/25/2017] [Indexed: 11/24/2022]
Abstract
BACKGROUND perineal injury is common after birth and may be caused by tears or episiotomy or both. Perineal massage has been shown to prevent episiotomies in primiparous women. On the other hand, pelvic floor exercises might have an influence by shortening the first and second stages of labour in the primigravida. AIM the aim of this study was to investigate the effects of a pelvic floor training following a birth programme on perineal trauma. DESIGN a single-blind quasi-randomized controlled trial with two groups: standard care and intervention. SETTING a tertiary, metropolitan hospital in Seville, Spain. PARTICIPANTS women (n=466) who were 32 weeks pregnant, having a singleton pregnancy and anticipating a normal birth were randomised. Women in the experimental groups were asked to perform a pelvic floor training programme that included: daily perineal massage and pelvic floor exercises from 32 weeks of pregnancy until birth. They were allocated to an intervention group by clusters (antenatal education groups) randomized 1:1. The control group had standard care that did not involve a perineal/pelvic floor intervention. These women were collected in a labour ward at admission 1:3 by midwives. RESULTS outcomes were analysed by intention-to-treat. Women assigned to the perineal/pelvic floor intervention showed a 31.63% reduction in episiotomy (50.56% versus 82.19%, p<0.001) and a higher likelihood of having an intact perineum (17.61% versus 6.85%, p<0.003). There were also fewer third (5.18% versus 13.12%, p<0.001) and fourth degree-tears (0.52% versus 2.5%, p<0.001). Women allocated to the intervention group also had less postpartum perineal pain (24.57% versus 36.30%, p<0.001) and required less analgesia in the postnatal period (21.14% versus 30.82%, p<0.001). CONCLUSIONS a training programme composed of pelvic floor exercises and perineal massage may prevent episiotomies and tears in primiparous women. This programme can be recommended to primiparous women in order to prevent perineal trauma. KEY CONCLUSION the pelvic floor programme was associated with significantly lower rates of episiotomies and severe perineal trauma; and higher intact perineum when compared with women who received standard care only. IMPLICATIONS FOR PRACTICE the programme is an effective intervention that we recommend to all women at 32nd week of pregnancy to prevent perineal trauma.

Abstract
INTRODUCTION Damage to the pelvic floor during vaginal childbirth is common, and may take the form of levator avulsion or irreversible overdistension of the levator hiatus (microtrauma). Such trauma is a major risk factor for pelvic organ prolapse later in life. In this study we aimed to identify intrapartum risk factors for levator trauma. MATERIAL AND METHODS This is a retrospective analysis of data obtained in two perinatal studies on primiparous women. Between 2005 and 2014, 1148 women carrying an uncomplicated singleton pregnancy in the late third trimester were seen for 4D pelvic floor ultrasound and an interview. They were invited for a repeat assessment at three months postpartum. RESULTS Of 1148 women, 871 (76%) returned for assessment at a mean of five months postpartum. The datasets of 844 women were analyzed due to missing data or concurrent pregnancy in 27. In all, 452 (54%) had a normal vaginal delivery, 102 (12%) a vacuum, 55 (6%) a forceps, and 235 (28%) a cesarean section. On multivariate analysis forceps, length of second stage and obstetric anal sphincter tears were significantly associated with levator avulsion. There were no significant predictors identified for irreversible overdistension. CONCLUSIONS The use of forceps, a prolonged second stage, and obstetric anal sphincter tears were associated with levator avulsion. There were no associated intrapartum predictors for hiatal overdistension.

Abstract
BACKGROUND There are a number of poor birth outcomes with advancing maternal age. Although there is some evidence of a higher risk of trauma to obstetric anal sphincter and the levator ani muscle with advancing age, findings to date are inconclusive. OBJECTIVE The aim of this study was to assess the risk of pelvic floor injury using translabial 3- and 4-dimensional ultrasound relative to advancing maternal age in primiparous women after a singleton vaginal delivery at term and to determine any association between maternal age and obstetric trauma, including obstetric anal sphincter injuries, levator avulsion, and irreversible overdistension of the levator hiatus. STUDY DESIGN This is a subanalysis of a perinatal intervention trial conducted in a specialist urogynecology referral unit at 2 tertiary units. All primiparous women with singleton birth at term underwent 3- and 4-dimensional translabial pelvic floor ultrasound both ante- and postnatally for the assessment of the obstetric trauma including levator ani muscle avulsion, hiatal overdistension to 25 cm(2) or more, and obstetric anal sphincter injuries. A multivariate logistic regression analysis was performed to examine the association between maternal age and obstetric trauma diagnosed on 3- and 4-dimensional translabial ultrasound. Multiple confounders were included, and the most significant (forceps and vacuum delivery) were used for probability modeling. RESULTS Of 660 women recruited for the original study, a total of 375 women who had a vaginal delivery with complete data sets were analyzed. A total of 174 women (46.4%) showed evidence of at least 1 form of major pelvic floor trauma. Advancing maternal age at first delivery carries with it a significant incremental risk of major pelvic floor trauma with an odds ratio of 1.064 for overall risk of injury for each increasing year of age past age 18 years (P = .003). The probability of any type of trauma appears to be substantially higher for forceps delivery. Vacuum delivery appears to increase the risk of obstetric anal sphincter injuries but not of levator avulsion. CONCLUSION There is a significant association between the risk of major pelvic floor injury and increasing maternal age at first delivery.
