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

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

Impact of educational workshops to increase awareness of pelvic floor dysfunction and integrate preventive lifestyle habits.

OBJECTIVES: Our objectives were to evaluate the impact of group pelvic floor education workshops on participants' knowledge, their satisfaction, and the modification of their urinary and digestive behaviors, and to compare health care providers' (HCP) knowledge with that of the general population. METHODS: For this prospective observational study, group pelvic floor education workshops were proposed between May 2021 and June 2022 in a web-conference format. Each workshop covered pelvic floor anatomy and physiology, urinary and digestive physiology as well as risk factors of PFD and preventive measures. At the start and the end of the workshops, participants completed a questionnaire on their knowledge and their beliefs about the pelvic floor. Questions about their satisfaction were asked at the end of the workshops. A 2-month questionnaire assessed changes in urinary and digestive habits and whether participants had talked about the workshop around them. RESULTS: A total of 856, with an average age 40.1 years, participated and completed the questionnaires before and after the workshops; 694 responded at 2 months. The education workshops significantly improved knowledge about the pelvic floor in the "HCP" and "non-HCP" groups. At 2 months, 591 participants (85.2%) 85.2% had talked about the workshop content; 557 (80.3%) reported having changed, or planned to change, their urinary behaviors and 495 (71.3%) their defecatory behaviors. CONCLUSIONS: Pelvic floor education workshops can increase level of knowledge and thus limit risky behaviors for the pelvic floor. The high rate of participation and the satisfaction of the participants shows the interest for the theme.

Image Enhancement Algorithm-Based Ultrasound on Pelvic Floor Rehabilitation Training in Preventing Postpartum Female Pelvic Floor Dysfunction.

In order to explore the application value of image enhancement algorithm in evaluating pelvic floor rehabilitation training in the prevention of postpartum female pelvic floor dysfunction (FPFD), 70 patients with FPFD were selected as the study subjects and randomly divided into two groups. One group received routine nursing (control group, n = 35), and the other group received pelvic floor rehabilitation training based on routine nursing (experimental group, n = 35). In ultrasound images based on an image enhancement algorithm, the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), and Pelvic Floor Distress Inventory-20 (PFDI-20) were used to evaluate the efficacy. The results showed that after image enhancement algorithm processing, the image signal-to-noise ratio (SNR), peak signal-to-noise ratio (PSNR), and structural similarity index (SSIM) of ultrasound images of patients with FPFD were significantly improved (P < 0.05); the mean square error (MSE) was significantly decreased (P < 0.05); the diagnostic accuracy of FPFD in the original ultrasound images was 73.34%, and that after image enhancement algorithm processing was significantly improved to be 89.86% (P < 0.05). In addition, the overall clinical response rate of FPFD in the experimental group (82.86%) was obviously higher than that in the control group (51.43%) (P < 0.05). After rehabilitation training, the ICIQ-SF and PFDI-20 scores of patients with FPFD in the two groups suggested a significant decrease (P < 0.05). In summary, using an image enhancement algorithm has a good application prospect in evaluating pelvic floor rehabilitation training in preventing postpartum FPFD and is worthy of further promotion.

The effectiveness of eHealth interventions on female pelvic floor dysfunction: a systematic review and meta-analysis.

INTRODUCTION AND HYPOTHESIS: eHealth interventions represent a promising novel strategy in pelvic floor management for women. Nevertheless, the effectiveness of eHealth interventions among women with or at risk of pelvic floor dysfunction (PFD) has not been adequately discussed to date. This study aimed to determine the effectiveness of eHealth interventions in preventing and treating PFD among women. METHODS: Eleven electronic databases were searched for randomized controlled trials (RCTs) from inception until August 28, 2021. RESULTS: Twenty-four RCTs were included in this meta-analysis that included 3691 women. The meta-analysis showed that eHealth interventions were not only vital for preventing PFD (pregnant women: pooled OR = 0.25, 95% CI: 0.14 to 0.45, p < 0.001; postnatal women: pooled OR = 0.19, 95% CI: 0.06 to 0.60, p = 0.005), but also for reducing the severity of PFD (pooled SMD = -0.63, 95% CI: -1.20 to -0.06, p = 0.031). In addition, compared with traditional care, eHealth interventions showed significant positive effects on several outcome indicators, including quality of life (pooled SMD = 0.49, 95% CI: 0.19 to 0.80, p = 0.002), pelvic floor type I muscle strength (pooled OR = 1.92, 95% CI: 1.30 to 2.82, p = 0.001), pelvic floor type II muscle strength (pooled OR = 2.04, 95% CI: 1.38 to 3.01, p < 0.001), sexual function (pooled SMD = 0.51, 95% CI: 0.29 to 0.73, p < 0.001), satisfaction (pooled OR = 3.93, 95% CI: 2.73 to 5.66, p < 0.001), and self-efficacy (pooled SMD = 2.62, 95% CI: 2.12 to 3.13, p < 0.001). CONCLUSIONS: eHealth interventions are an effective emerging treatment and preventive modality for female PFD. Higher quality, larger scale, and strictly designed RCTs are warranted to evaluate the effectiveness of eHealth interventions on female pelvic floor management.

Episiotomy in vacuum extraction, do we cut the levator ani muscle? A prospective cohort study.

INTRODUCTION AND HYPOTHESIS: Vaginal delivery may lead to levator ani muscle (LAM) injury or avulsion. Episiotomy may reduce obstetric anal sphincter injury in operative vaginal delivery, but may increase the risk of LAM injury. Our aim was to assess whether lateral episiotomy in vacuum extraction (VE) in primiparous women causes LAM injury. METHODS: A prospective cohort study of 58 primiparous women with episiotomy nested within an ongoing multicenter randomized controlled trial of lateral episiotomy versus no episiotomy in VE (EVA trial) was carried out in Sweden. LAM injury was evaluated using 3D endovaginal ultrasound 6-12 months after delivery and Levator Ani Deficiency (LAD) score. Episiotomy scar properties were measured. Characteristics were described and compared using Chi-squared tests. We stipulated that if a lateral episiotomy cuts the LAM, ≥50% would have a LAM injury. Among those, ≥50% would be side specific. We compared the observed prevalence with a test of one proportion. RESULTS: Twelve (20.7%, 95% CI 10.9-32.9) of 58 women had a LAD (p < 0.001, compared with the stipulated 50%). Six (50.0%, 95% CI 21.1% to 78.9%) of 12 women had a LAD on the episiotomy side, including those with bilateral LAD (p = 1.00). Two (16.7%, 95% CI 2.1% to 48.4%) of 12 women had a LAD exclusively on the episiotomy side (p = 0.02). CONCLUSIONS: There was no excessive risk of cutting the LAM while performing a lateral episiotomy. LAD was not seen in women with episiotomies shorter than 18 mm.

Should pregnant women know their individual risk of future pelvic floor dysfunction? A qualitative study.

BACKGROUND: The study aimed to explore: • pregnant women's and healthcare professionals' perspectives on provision of individual risk scores for future Pelvic Floor Dysfunction (PFD), • the feasibility of providing this during routine maternity care, • actions women might take as a result of knowing their PFD risk. METHODS: Qualitative study. SETTING: UK NHS Health Board. PARTICIPANTS: Pregnant women (n = 14), obstetricians (n = 6), midwives (n = 8) and physiotherapists (n = 3). A purposive sample of pregnant women and obstetric healthcare professionals were introduced to the UR-CHOICE calculator, which estimates a woman's PFD risk, and were shown examples of low, medium and high-risk women. Data were collected in 2019 by semi-structured interview and focus group and analysed using the Framework Approach. RESULTS: Women's PFD knowledge was limited, meaning they were unlikely to raise PFD risk with healthcare professionals. Women believed it was important to know their individual PFD risk and that knowledge would motivate them to undertake preventative activities. Healthcare professionals believed it was important to discuss PFD risk, however limited time and concerns over increased caesarean section rates prevented this in all but high-risk women or those that expressed concerns. CONCLUSION: Women want to know their PFD risk. As part of an intervention based within a pregnant woman/ maternity healthcare professional consultation, the UR-CHOICE calculator could support discussion to consider preventative PFD activities and to enable women to be more prepared should PFD occur. A randomised controlled trial is needed to test the effectiveness of an intervention which includes the UR-CHOICE calculator in reducing PFD.

Transvaginal natural orifice specimen extraction surgery (NOSES) in 3D laparoscopic partial or radical nephrectomy: a preliminary study.

BACKGROUND: With the development of minimally invasive technology, more and more people pay attention to aesthetics of the wound after operation. This study is aim to introduce a new surgical technique of transvaginal natural orifice specimen extraction surgery (NOSES) in 3D laparoscopic partial or radical nephrectomy and evaluate the safety, feasibility and clinical effect. METHODS: Eleven patients who underwent 3D laparoscopic partial nephrectomy (n = 7) or radical nephrectomy (n = 4) and NOSES were included in this study. The surgical procedures and techniques, especially the NOSES operation, are reported in detail. In addition, the basic clinical data, perioperative related data, perioperative complications were analyzed. RESULTS: All 11 patients were performed successfully without conversion to open surgery. The mean total operative time was 133 (84, 150) min. NOSES time was 15 (13, 16) min, and the postoperative hospital stay was 5 (5, 5) d. The mean visual analogue score (VAS) was 3 (2, 4) point and 1 (0, 1) point at 24 h and 48 h after operation, respectively. No patient had recurrence, metastasis and death during the follow-up period of 3 to 17 months. The median Vancouver Scar Scale (VSS) was 1 (1, 1) point. The mean of Female Sexual Function Index (FSFI) was 21.60 (20.20, 21.60), 21.80 (19.80, 21.80) respectively between preoperative and postoperative 3 months, which has no statistical difference (P = 0.179). There was no statistical difference in the Pelvic Floor Distress Inventory-short form 20 (PFDI-20) score between preoperative and postoperative 3 months (P = 0.142). CONCLUSIONS: Transvaginal NOSES is safe and feasible in 3D laparoscopic partial or radical nephrectomy. Furthermore, it results in low incision-related pain without affecting the pelvic floor and sexual function.

Clinical prediction is at the heart of preventing birth trauma and pelvic floor disorders for individual women.

INTRODUCTION AND HYPOTHESIS: The purpose of this article is to understand that the majority of studies investigating the role of risk factors for maternal birth trauma and pelvic floor disorders are designed using causal inferential statistical methods and have not been designed to investigate the more useful goal of clinical prediction. METHODS: A review of the literature was conducted to describe notable causal and predictive associations between risk factors and maternal birth trauma outcomes. Examples were obtained to illustrate and contrast differences in clinical usefulness between causal and predictive models. RESULTS: Effects of pregnancy and childbirth on the risk of maternal birth trauma outcomes and subsequent pelvic floor disorders are an area of profound investigation. Numerous observational studies provide evidence that pregnancy and childbirth play a causal role in the increasing prevalence of these outcomes, and clinicians must rely on this observational evidence to guide decisions about preventing maternal birth trauma and pelvic floor disorders. However, there are important differences between the design and evaluation of models for a predictive context including: study design goals, inclusion or exclusion of candidate risk factors, model evaluation and the additional need to assess model error. CONCLUSION: This article contrasts how causal and predictive modeling approaches are different and argues that indiscriminately modeling risk factors for birth trauma and pelvic floor disorder outcomes is costly to women.

Efficacy of Community-based Pelvic Floor Muscle Training to Improve Pelvic Floor Dysfunction in Chinese Perimenopausal Women: A Randomized Controlled Trial.

To evaluate the effectiveness of pelvic floor muscle training (PFMT) on perimenopausal women with pelvic floor dysfunction (PFD). A two-group longitudinal experimental design with multiple comparisons. The intervention group (n = 37) received a 3-month intervention combining Kegel and yoga exercise. The control group (n = 37) received Kegel exercise. The combined training alleviated PFD symptoms, improved life quality and increased pelvic floor muscle strength of perimenopausal women. Women with PDF symptoms can integrate PFMT and yoga exercise to promote rehabilitation and improved outcomes. Combined exercise should be taught and practiced under supervision by qualified health professionals.

The Effect of Commonly Performed Exercises on the Levator Hiatus Area and the Length and Strength of Pelvic Floor Muscles in Postpartum Women.

OBJECTIVE: The aim oft his study was to compare the effects of 10 common exercises to traditional pelvic floor muscle (PFM) contractions (Kegel) on levator hiatus (LH) area and PFM length and strength. METHODS: This is a cross-sectional study of 15 healthy postpartum women. Ten exercises were studied. These were common variations of leg, core, and back exercises used in yoga, Pilates, strength training, and physical therapy. Each participant performed all 10 exercises at a single visit in 2 examination settings: transperineal ultrasound and perineometry. Ultrasound measured the LH area and PFM length, and perineometry measured the muscle strength (peak squeeze pressure). RESULTS: Kegel generates an increase in squeeze pressure (24.3 cm H2O), shortens the muscles (-0.46 cm) and narrows the LH (-0.13 cm). The bird-dog and plank exercises were not different from Kegel in any measurement. While the leg-lift ultrasound dimensions are similar to Kegel, leg lifts generated peak squeeze pressures stronger than any other exercise (including Kegel). Whereas ultrasound dimensions were similar to Kegel, tucked and untucked squats and thigh adductions generated weaker contractions than Kegel. While crunch generated a squeeze pressure similar to Kegel, the ultrasound dimensions showed a significantly wider LH and longer muscle than Kegel. Bridge, clam, and plié exercises affected the PFMs differently than Kegel in all measures. CONCLUSIONS: Bird-dog, plank, and leg-lift exercises should be evaluated as alternative exercises to Kegel as they affect PFM strength and length and LH area similarly to Kegel, and leg lifts generate a stronger contraction than Kegel.

Cesarean delivery to prevent anal incontinence: a systematic review and meta-analysis.

BACKGROUND: Cesarean delivery (CD), is increasingly recommended as a mode of delivery that prevents the anal incontinence (AI) that arises in some women after vaginal delivery (VD). The assessment of the efficacy of CD in this regard was the subject of this systematic review. METHODS: Searches were conducted in Medline, EMBASE and the Cochrane Library. Both randomized (RCTs) and non-randomized trials (NRTs) comparing the risk of sustained fecal and/or flatus incontinence after VD or CD were sought from 1966 to 1 January, 2019. Studies were eligible if they assessed AI more than 6 months after birth, and had statistical adjustment for at least one of the three major confounders for AI: age, maternal weight or parity. In addition, each study was required to contain more than 250 participants, more than 50 CDs and more than 25 cases of AI. Data after screening and selection were abstracted and entered into Revman for meta-analysis. Analyses were done for combined fecal and flatus incontinence (comAI), fecal incontinence (FI), gas incontinence (GI), CD before or during labor, time trend of incontinence after delivery, assessment of both statistical and clinical heterogeneity, parity and late incident AI. RESULTS: Out of the 2526 titles and abstracts found, 24 eligible studies were analyzed, 23 NRTs and one RCT. These included women with 29,597 VDs and women with 6821 CDs. Among the primary outcomes, VD was found not to be a significant predictor of postpartum comAI compared to CD in 6 studies, incorporating 18,951 deliveries (OR = 0.74; 0.54-1.02). VD was also not a significant predictor of FI in 14 studies, incorporating 29,367 deliveries, (OR = 0.89; 0.76-1.05). VD was not a significant predictor of GI in six studies, incorporating 6724 deliveries (OR = 0.96; 0.79-1.18). The strength of the grading of recommendations, assessment, development and evaluations (GRADE) evidence for each of these was low for comAI and moderate for FI and GI (upgrade for lack of expected effect). Time trend FI showed incontinence at 3 months often resolved at 1 year. Other secondary analyses assessing parity, delayed incidence of FI, clinical and statistical heterogeneity, spontaneous VD only, late risk of incidence of AI, and CD in or prior to labor all had similar results as in the primary outcomes. CONCLUSIONS: There are three components of pelvic floor dysfunction that are thought to be caused by VD and hopefully prevented by CD: AI, urinary incontinence and pelvic floor prolapse. Of these, AI was not found to be reliably prevented by CD in this review.

Empty pelvis syndrome: the use of breast prosthesis in the prevention of complications.

AIM: Empty pelvis syndrome and radiation-induced bowel injury are two major clinical issues resulting from the pelvic dead space after pelvic exenteration (PE). In order to avoid these complications, different methods of pelvic floor reconstruction have been proposed. We report our experience on the use of breast prosthesis. METHOD: Fifty-three patients who underwent PE and three who underwent palliative surgery with silicone breast prosthesis placement were included. RESULTS: Forty-seven posterior PE, six total PE and three palliative procedures were identified. Sphincter preservation was feasible in 34 patients (62.3%). There were no deaths. Overall morbidity was 37.5%. There were no complications such as sepsis or obstruction related to the prosthesis. Adjuvant radiotherapy was delivered in 16 cases (30.1%) without any side-effects. Reconstruction of intestinal continuity was possible in 12 patients (36.3%) with sphincter preservation and the prosthesis allowed a prompt identification of the rectal stump. CONCLUSION: Breast prosthesis placement is a simple and safe method to minimize complications resulting from empty pelvis syndrome and can be adopted to exclude bowel loops from the radiation field. Reconstruction of intestinal continuity after resection is also simplified.

Episiotomy in modern clinical practice: friend or foe?

The Cochrane library first published a meta-analysis in 2000 on the role of the episiotomy in modern clinical practice, which concluded that only a policy of selective episiotomy is acceptable with evidence-based improvement in maternal health compared with routine episiotomy. Many years later, however, the new version of the Cochrane meta-analysis changed the previous recommendations in that the selective use of episiotomy could not be considered beneficial in all cases. A selective policy is associated with a statistically significant reduction in severe perineal and/or vaginal trauma, whereas routine episiotomy seems to protect against these complications only after instrumental deliveries. Both in the short and the long term, selective medio-lateral episiotomy has no additional beneficial effects without clear evidence of causing harm to the mother or baby.

Knowledge of pelvic floor disorder in pregnancy.

INTRODUCTION AND HYPOTHESIS: Pelvic floor dysfunction is a common condition which can lead to distressing consequences such as urinary incontinence (UI), pelvic organ prolapse (POP) and fecal incontinence (FI). Pregnancy is a known major risk factor. This study aims to assess the level of knowledge about pelvic floor disorders among pregnant women in our local population. METHODS: A cross-sectional study was conducted in a population of pregnant women in their third trimester. A 47-question questionnaire was distributed to a random sample group. Knowledge scores were calculated. Possible predictive factors for knowledge level such as age, ethnicity, parity, ethnicity and educational levels were studied. RESULTS: Thirty-three out of 104 respondents (31.7%) reported history of urinary incontinence, 3 respondents (2.9%) reported sensation of prolapse, and 1 respondent (0.96%) reported fecal incontinence. The knowledge score for urinary incontinence was the highest at 46.2% and lowest in pelvic organ prolapse at 35.3%. Mean knowledge scores increased significantly with age (p = 0.021) and educational level (p = 0.046). The nulliparous women scored higher than the multiparous women. Age and educational level had a significant impact on multivariate analysis scores. CONCLUSIONS: The knowledge on pelvic floor disorders is poor among our local pregnant women. Healthcare professionals should place increased emphasis on advocating pelvic floor exercises for pregnant women during their routine antenatal care.

Evaluation of the effect of an antenatal pelvic floor muscle exercise programme on female sexual function during pregnancy and the first 3 months following birth: study protocol for a pragmatic randomised controlled trial.

BACKGROUND: Sexual dysfunction can have a negative impact on women's quality of life and relationships. There is limited information about female sexual function and treatment, particularly during pregnancy and the postpartum period. The effect of pelvic floor muscle exercise (PFME) on sexual function (SF) has not been studied adequately. The purpose of this study is to investigate the effect of antenatal PFME on female SF during pregnancy and the first 3 months following birth. METHODS/DESIGN: This is a pragmatic, randomised controlled trial which will compare a structured antenatal PFME programme combined with standard antenatal care to standard antenatal care alone. Eligible women who are less than 22 weeks' gestation will be recruited from the antenatal clinics of one hospital located in Western Sydney, Australia. A sample of 200 primiparous pregnant women who meet the inclusion criteria will be randomised to either control or intervention groups. This sample size will allow for detecting a minimum difference of 9% in the female SF score between the two groups. The duration of the PFME programme is from approximately 20 weeks' gestation until birth. Female SF will be measured via questionnaires at < 22 weeks' gestation, at 36 weeks' gestation and at 3 months following birth. Baseline characteristics, such as partner relationship and mental health, will be collected using surveys and questionnaires. Data collected for secondary outcomes include the effect of PFME on childbirth outcomes, urinary and faecal incontinence symptoms and quality of life. DISCUSSION: The findings of this study will provide more information on whether a hospital-based antenatal PFME has any effect on female SF, urinary and faecal incontinence during pregnancy and the first 3 months following birth. The study will also provide information on the effectiveness of antenatal PFME on childbirth outcomes. TRIAL REGISTRATION: Australian New Zealand Clinical Trials registry, ACTRN12617001030369 .

Perineal outcome following educational intervention: a retrospective audit of primiparous women.

The management of vaginal delivery appears to offer an opportunity to reduce the morbidity of pelvic floor dysfunction (PFD) which is very common in the postpartum period. Research by the authors suggests that an episiotomy is protective against PFD, in particular urinary incontinence. The aim of this subsequent audit was to see if educational intervention can alter the common medical practice of episiotomy and in turn reduce postpartum PFD. Nine hundred and fifty four primiparous women with a non-instrumental vaginal delivery were included, of which 30% had an intact perineum, 51% a spontaneous tear and 19% an episiotomy. The intervention was a teaching session by the Head of Urogynaecology encompassing the anatomy, the impact of a vaginal delivery on PFD, in addition to local and international research. Whilst no significant difference was noted overall in the episiotomy rates as a result of the educational intervention (p = .17), significant differences were noted with the different accoucheur types. Where the accoucheur was an obstetrician or obstetrics registrar, the episiotomy rates increased from 56% to 70% (p < .01); where the midwife was the accoucheur the episiotomy rate changed minimally (11-18%, respectively; p = .27). This demonstrates that feedback about the provider's own practice patterns can change the behaviour to conform with the agreed upon standards. Impact Statement What is already known on this subject? Pelvic floor dysfunction (PFD) is the most common complication of childbirth, affecting approximately 85% of Australian women following a vaginal delivery. A link has been made between the perineal outcome and PFD, which has a significant impact on the quality of life. Previous research suggests that the management of a vaginal delivery offers an opportunity to reduce its morbidity, with an episiotomy being protective. However, there is a wide variation in the use of episiotomy which ranges from 9% to 100%. What the results of this study add? The literature suggests that the strongest factor associated with the episiotomy rates arises from differences in the attitude and training. Consequently, this study explored whether an educational intervention can change the common medical practice of episiotomy and in turn reduce postpartum PFD. What are the implications of these findings for clinical practice and/or further research? No significant difference was noted overall in the episiotomy rates as a result of the educational intervention, however, the response to the educational intervention was varied among the different types of accoucheurs with the obstetricians, obstetric registrars and student midwives significantly increasing their rate of episiotomy, whilst the midwives demonstrated no significant change. This suggests that there are contributing factors which may include past education and experience; this is an area for further research.

[Comparison of pelvic floor muscle strength in competition-level athletes and untrained women].

INTRODUCTION: Exercise can stress the pelvic floor muscles. Numerous women experience urinary incontinence while exercising or competing in sports. This study investigated pelvic floor muscle strength, urinary incontinence, and knowledge in contracting pelvic floor muscles among female athletes and untrained women. MATERIALS AND METHODS: This was a prospective case-control study measuring pelvic floor muscle strength using vaginal pressure meas-urement. Participants answered questions regarding general health, urinary incontinence, and knowledge on pelvic floor muscles. Partici-pants were healthy nulliparous women aged 18-30 years, athletes and untrained women. The athletes had competed in their sport for at least three years; including handball, soccer, gymnastics, badminton, BootCamp and CrossFit. RESULTS: The women were comparable in age and height. The athletes (n=18) had a body mass index (BMI) of 22.8 kg/m² vs. 25 kg/m² for the untrained (n=16); p<0.05. The athletes trained on average 11.4 hours/week while the untrained women participated in some activity on average for 1.3 hours/week; p< 0.05. Mean pelvic floor strength was 45±2 hPa in the athletes vs. 43±4 hPa in the untrained; p=0.36 for whether the athletes were stronger. Of the athletes, 61.1% experienced urinary incontinence (n=11) compared with 12.5% of the untrained women (n=2); p<0.05. Incontinence usually occurred during high intensity exercise. The athletes were more knowledgeable about the pelvic floor muscles; p<0.05. CONCLUSION: There was not a significant difference in the strength of pelvic floor muscles of athletes and untrained women. This suggests that pelvic floor muscles are not strengthened during general training but require specific exercises. This holds especially for football, handball and sports with high physical intensity. Coaches need to pay special attention to training and strengthening women's pelvic floor muscles to reduce the occurrence of urinary incontinence.
