Volumetric segmentation analysis of the levator ani muscle using magnetic resonance imaging in pelvic floor function assessment

PURPOSE

In this case-control study, we aimed to evaluate how muscle volume affects pelvic floor function by analyzing the levator ani muscle (LAM) using volumetric segmentation in addition to standard magnetic resonance (MR) defecography assessments.

METHODS

We enrolled 85 patients with varying degrees of pelvic floor dysfunction (PFD) and 85 age- and gender-matched controls in this retrospective study. All patients had MR defecography images, while all controls had pelvic MR images obtained for other reasons. Group comparisons were performed using independent samples t-tests and Mann-Whitney U tests. The receiver operating curve (ROC) was constructed to establish a cut-off value for a normal LAM volume. Interrater reliability was assessed by calculating the intraclass correlation coefficient. A P value of less than 0.05 was considered statistically significant.

RESULTS

Volumetric measurements revealed that the control group had higher LAM volumes, and the ROC curve analysis indicated a cut-off value of 38934.3 mm3 with a sensitivity of 0.812 and specificity of 0.8 for PFD assessment using LAM volumetric measurement. Gender did not significantly affect LAM volume in the control group.

CONCLUSION

Alongside the useful structural and functional information acquired from MR defecography images, volumetric analysis, and three-dimensional reconstructions of LAM may help to improve the accuracy of the diagnosis.

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

OBJECTIVE

To investigate the effect of vacuum extraction (VE) or caesarean section (CS), compared with expectant management, on pelvic floor dysfunction (PFD) 1-2 years postpartum in primiparous women with a prolonged second stage of labour.

DESIGN

A population-based questionnaire and cohort study.

SETTING

Stockholm, Sweden.

POPULATION

A cohort of 1302 primiparous women with a second stage duration of ≥3 h, delivering from December 2017 to November 2018.

METHODS

The 1-year follow-up questionnaire from the Swedish National Perineal Laceration Register was distributed 12-24 months postpartum. Exposure was VE or CS at 3-4 h or 4-5 h, compared with expectant management.

MAIN OUTCOME MEASURES

Pelvic floor dysfunction was defined as at least weekly symptoms of urinary incontinence, pelvic organ prolapse or a Wexner score of ≥4. The risk of PFD was calculated using Poisson regression with robust variance estimation, presented as crude and adjusted relative risks (RRs and aRRs) with 95% confidence intervals (95% CIs). The implication of obstetric anal sphincter injury (OASI) on pelvic floor disorders was investigated through mediation analysis.

RESULTS

In total, 35.1% of women reported PFD. Compared with expectant management, the risk of PFD was increased after VE at 3-4 h (aRR 1.33, 95% CI 1.06-1.65) and 4-5 h (aRR 1.34, 95% CI 1.05-1.70), but remained unchanged after CS. The increased risk after VE was not mediated by OASI.

CONCLUSIONS

Pelvic floor dysfunction was common in primiparous women after a prolonged second stage, and the risk of PFD increased after VE but was unaffected by CS, compared with expectant management. If a spontaneous vaginal delivery eventually occurred, allowing an extended duration of labour did not increase the risk of PFD.

Pelvic Floor Dysfunction among Reproductive-Age Women in Israel: Prevalence and Attitudes-A Cross-Sectional Study

Objectives: Our study aimed to investigate the prevalence of female pelvic floor dysfunction (PFD) in Israeli women who experienced vaginal delivery and are in their reproductive years (premenopausal), as well as to understand their attitudes and health-seeking behavior and barriers towards treating this problem. Methods: In this cross-sectional study, we conducted a questionnaire-based Internet survey. The surveys were sent to Israeli women in their fertile years (18-50 years old). We asked the women about their PFD symptoms, attitudes, and help-seeking behaviors. We used two validated questionnaires, including the USIQ and the PFDI-20. The combined questionnaire was submitted in both Hebrew and Arabic. We assessed the prevalence of PFD symptoms in the study population. Symptomatic women were asked about their help-seeking behaviors and their beliefs, desires, and barriers regarding the clinical management of symptoms. Results: Between July and September 2020, 524 women completed the questionnaire (response rate 44%). In total, 95% reported at least one symptom (mostly urinary-related) at any grade of severeness in at least one category, and 66.8% suffered from at least one moderate to severe symptom in at least one category. Most women (93.7%) reported that they wanted to be asked and offered voluntary information about PFD from physicians and nurses; however, only 16.6% reported receiving such information. Barriers to seeking treatment were mainly related to low awareness. The study's main limitation was selection bias due to the questionnaire's design. Conclusions: These findings show the importance of raising awareness of the different therapeutic solutions to PFD symptoms and designing more available services for this common problem.

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.

A Narrative Review on the Viability of Osteopathic Manipulative Medicine in Treating Irritable Bowel Syndrome With Constipation (IBS-C)

Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by chronic abdominal pain and alterations in bowel habits, with global prevalence. The etiology of the disease is likely multifactorial; however, autonomic nervous system (ANS) dysfunction and immune-mediated inflammation may contribute the most to the hallmark symptoms of abdominal pain and altered motility of the gut. Current pharmacological therapies operate to modulate intestinal transit, alter the composition of the gut flora and control pain. Non-pharmacological approaches include dietary changes, increased physical activity, or fecal microbiota transplants. None of these therapies can modulate ANS dysfunction or impact the underlying inflammation that is likely perpetuating the symptoms of IBS. Osteopathic Manipulative Medicine (OMM) is a clinical approach focused on physical manipulation of the body's soft tissues to correct somatic dysfunctions. OMM can directly target the pathophysiology of IBS through many approaches such as ANS modulation and lymphatic techniques to modify the inflammatory mechanisms within the body. Particular OMM techniques of use are lymphatic manipulation, myofascial release, sympathetic ganglia treatment, sacral rocking, counterstrain, and viscerosomatic treatment. The aim of this study is to identify OMM treatments that can be used to potentially reduce the inflammation and ANS dysfunction associated with IBS symptoms, thereby providing a new non-pharmacological targeted approach for treating the disease.

Finite element analysis of female pelvic organ prolapse mechanism: current landscape and future opportunities

The prevalence of pelvic organ prolapse (POP) has been steadily increasing over the years, rendering it a pressing global health concern that significantly impacts women's physical and mental wellbeing as well as their overall quality of life. With the advancement of three-dimensional reconstruction and computer simulation techniques for pelvic floor structures, research on POP has progressively shifted toward a biomechanical focus. Finite element (FE) analysis is an established tool to analyze the biomechanics of complex systems. With the advancement of computer technology, an increasing number of researchers are now employing FE analysis to investigate the pathogenesis of POP in women. There is a considerable number of research on the female pelvic FE analysis and to date there has been less review of this technique. In this review article, we summarized the current research status of FE analysis in various types of POP diseases and provided a detailed explanation of the issues and future development in pelvic floor disorders. Currently, the application of FE analysis in POP is still in its exploratory stage and has inherent limitations. Through continuous development and optimization of various technologies, this technique can be employed with greater accuracy to depict the true functional state of the pelvic floor, thereby enhancing the supplementation of the POP mechanism from the perspective of computer biomechanics.

Digital Care Program for Urinary Incontinence in Females: A Large-Scale, Prospective, Cohort Study

Female urinary incontinence (UI) is highly prevalent in the US (>60%). Pelvic floor muscle training (PFMT) represents first-line care for UI; however, access and adherence challenges urge new care delivery models. This prospective cohort study investigates the feasibility and safety of a remote digital care program (DCP) combining education and PFMT with real-time biofeedback with an average duration of 10 weeks. The primary outcome was the change in the Urinary Impact Questionnaire-short form (UIQ-7) from baseline to program-end, calculated through latent growth curve analysis (LGCA). Secondary outcomes included the impact of pelvic conditions (PFIQ-7), depression (PHQ-9), anxiety (GAD-7), productivity impairment (WPAI), intention to seek additional healthcare, engagement, and satisfaction. Of the 326 participants who started the program, 264 (81.0%) completed the intervention. Significant improvement on UIQ-7 (8.8, 95%CI 4.7; 12.9, p < 0.001) was observed, corresponding to a response rate of 57.3%, together with improvements in all other outcomes and high satisfaction (8.9/10, SD 1.8). This study shows the feasibility and safety of a completely remote DCP with biofeedback managed asynchronously by a physical therapist to reduce UI-related symptoms in a real-world setting. Together, these findings may advocate for the exploration of this care delivery option to escalate access to proper and timely UI care.

Urinary Incontinence and Other Pelvic Floor Dysfunctions as Underestimated Problems in People under Forty Years: What Is Their Relationship with Sport?

Urinary incontinence is still an underestimated problem due to its anatomical complexity and social taboo. Most of the time, it is believed to affect predominantly the elderly female population, and the literature still lacks data on its presence in the younger and male populations. Its relationship with other pelvic floor dysfunctions (PFDs) and sport activity remains an open topic. Thus, the present study surveyed 342 subjects of both genders, ranging from 18 to 39 y/o and with different sport activity levels, to understand the prevalence of PFDs (such as haemorrhoids, anal fissures, involuntary urinary/faecal leakage, and urgency). The results also showed a significative prevalence in younger, sporty, and male people. Approximately one third of the population had urinary incontinence mostly during stress activities (sport activity: 17%, cough/sneeze: 13%). The statistical analysis confirmed a higher prevalence in the cases of a light (32%) and intense (41%) sport activity level and a protective role of sport if practiced between 5 and 10 h/week, with bodybuilding/CrossFit and running seeming to be the riskiest sports. The relationship with the other PFDs showed a statistically significant dependence with most of them, confirming that urinary incontinence cannot be considered a separate problem from the other PFDs.

Developing new ways to assess neural control of pelvic organ function in spinal conditions: ICI-RS 2023

OBJECTIVES

Several central nervous system (CNS) centers affect muscle groups of the lower urinary tract (LUT) and anorectal tract (ART) via autonomic and somatic pathways, working in different modes (storage or expulsion). Hence spinal cord dysfunction can affect the LUT and ART by several possible mechanisms.

METHODS

This review reports the discussions of a workshop at the 2023 meeting of the International Consultation on Incontinence Research Society, which reviewed uncertainties and research priorities of spinal dysfunction.

RESULTS

Discussion focussed on the levator ani nerve, mechanisms underpinning sensory function and sensation, functional imaging, dyssynergia, and experimental models. The following key research questions were identified. (1) Clinically, how can we evaluate the levator ani muscle to support assessment and identify prognosis for effective treatment selection? (2) How can we reliably measure levator ani tone? (3) How can we evaluate sensory information and sensation for the LUT and the ART? (4) What is the role of functional CNS imaging in development of scientific insights and clinical evaluation? (5) What is the relationship of detrusor sphincter dyssynergia to renal failure?

CONCLUSIONS

Spinal cord dysfunction can fundamentally disrupt LUT and ART function, with considerable clinical impact. The evaluation needs to reflect the full scope of potential problems, and new clinical and diagnostic approaches are needed, for prognosis and treatment. The preclinical science evaluating spinal cord function in both LUT and ART storage and elimination remains a major priority, even though it is a challenging experimental context. Without this underpinning evidence, development of new clinical evidence may be held back.

Restoration of bladder neck activity and levator hiatus dimensions in Asian primipara: a prospective study

Pelvic floor muscle training (PFMT) reduces the symptoms in women with pelvic floor dysfunction (PFD); however, the optimal initial timing for secondary prevention of PFD by PFMT is not clear. To identify the optimal timing in Asian primiparas with vaginal delivery, bladder neck descent (BND), levator hiatus areas, and levator hiatus distensibility and contractility were assessed in 26 nulliparous women at 36 weeks of gestation and at 2, 4, 6, and 12 weeks postpartum. We found that BND increased significantly from 2 weeks onwards until 6 weeks postpartum (p = 0.004); the levator hiatus area at rest and contraction both showed the largest value at 2 weeks postpartum (p = 0.005 and p < 0.005 respectively), followed by a continuous decrease; the hiatus area during Valsalva manoeuvre, and the levator hiatus distensibility and contractility showed the lowest value at 2 weeks postpartum, followed by a continuous increase; the changes in BND showed no correlation with the changes in distensibility or hiatus area during Valsalva manoeuvre (p = 0.073 and 0.590 respectively). In Asian primiparas with vaginal delivery, the recovery of levator hiatus and bladder neck mobility begins at 2 and 6 weeks, respectively. This information could be useful in defining the best time to begin PFMT for secondary prevention of postpartum PFD in Asian primiparous women.IMPACT STATEMENTWhat is already known on this subject? Pelvic floor muscle training (PFMT) helps to reduce symptoms of pelvic floor dysfunction (PFD), however, there are no clear time strategies for the secondary prevention of PFD by PFMT in Asian primiparas with vaginal delivery.What do the results of this study add? This study was the first longitudinal study in Asian primipara to investigate the natural regeneration of pelvic floor functions in the early postpartum period by intensively monitoring the bladder neck mobility and levator hiatus dimensions at multiple time points. We found that bladder neck descent (BND) increased significantly from 2 weeks onwards until 6 weeks postpartum; the levator hiatus area at rest and contraction both showed the largest value at 2 weeks postpartum, followed by a continuous decrease; the hiatus area during Valsalva manoeuvre, and the levator hiatus distensibility and contractility showed the lowest value at 2 weeks postpartum, followed by a continuous increase; the changes in BND showed no correlation with the changes in distensibility or hiatus area during Valsalva manoeuvre.What are the implications of these findings for clinical practice and/or further research? Our study suggested that in Asian primipara, the recovery of bladder neck mobility after vaginal delivery begins at 6 weeks postpartum, while the levator hiatus muscle begins to recover within the first 2 weeks postpartum. Therefore, it could be useful in deciding the best time to start PFMT for secondary prevention of postpartum PFD in Asian primiparous women.

Comparison of Dynamic Magnetic Resonance Defecography With Clinical Examination in Diagnosing Pelvic Floor Dysfunction: An Observational Study

BACKGROUND

Pelvic floor dysfunction (PFD) is frequently reported in both sexes. Dynamic magnetic resonance defecography (DMRD) is the preferred modality, mainly due to its superiority and complementary role in clinical examination. However, studies from the perspective of Indian patients are scarce and mostly restricted to females. Thus, we assessed the diagnostic performance of DMRD in patients with PFD and correlated the findings with those on clinical examination.

MATERIALS AND METHODS

This prospective, observational study involved 57 adult patients of either sex, presenting with pelvic floor symptoms (PFS) and diagnosed with PFD. Initially, the patients underwent clinical examination, and diagnosis was recorded. Subsequently, the patients were subjected to DMRD. The findings were correlated with the Pearson "r" correlation coefficient.

RESULTS

A significantly greater proportion of patients had involvement of multiple compartments (36 vs. 12, p<0.001), cystocele (23 vs. 8, p=0.002), and rectal prolapse (25 vs. 14, p=0.030) on DMRD than clinical examination, while there was no significant difference regarding uterine prolapse (p=0.789). Grading of cystocele and rectal prolapse as well as diagnosis of enterocele/peritoneocele, rectocele, and intussusception could be done only with DMRD. DMRD had a strong and significant correlation with clinical examination regarding cystocele (r=0.943, p=0.003), uterine prolapse (r=0.972, p=0.001), and rectal prolapse (r=0.951, p=0.001).

CONCLUSIONS

DMRD demonstrated significantly better performance in the diagnosis of multiple compartment involvement, cystocele, and rectal prolapse. DMRD and clinical examination were significantly correlated regarding the diagnosis of cystocele, uterine prolapse, and rectal prolapse. Thus, DMRD provides information, in addition to the clinical examination, and should be used in symptomatic patients.

Functional neuroimaging related to lower urinary tract sensations: Future directions for study designs and selection of patient groups: ICI-RS 2023

OBJECTIVES

Neuroimaging studies have advanced our understanding of the intricate central nervous system control network governing lower urinary tract (LUT) function, shedding light on mechanisms for urine storage and voiding. However, a lack of consensus in methodological approaches hinders the comparability of results among research groups and limits the translation of this knowledge to clinical applications, emphasizing the need for standardized methodologies and clinical utilization guidelines.

METHODS

This paper reports the discussions of a workshop at the 2023 meeting of the International Consultation on Incontinence Research Society, which reviewed uncertainties and research priorities to progress the field of neuroimaging in LUT control and dysfunction.

RESULTS

Neuroimaging holds great potential for improving our understanding of LUT control and pathophysiological conditions. To date, functional neuroimaging techniques have not yet achieved sufficient strength to make a direct clinical impact. Potential approaches that can improve the clinical utilization of neuroimaging were discussed and research questions proposed.

CONCLUSIONS

Neuroimaging offers a valuable tool for investigating LUT control, but it's essential to acknowledge the potential for oversimplification when interpreting brain activity due to the complex neural processing and filtering of sensory information. Moreover, technical limitations pose challenges in assessing key brain stem and spinal cord centers, particularly in cases of neurological dysfunction, highlighting the need for more reliable imaging of these centers to advance our understanding of LUT function and dysfunction.

Menopause and stress urinary incontinence: The risk factors of stress urinary incontinence in perimenopausal and postmenopausal women

OBJECTIVE

The prevalence of stress urinary incontinence (SUI) increases around menopause. The quality of life of perimenopausal and postmenopausal women with SUI is significantly affected. This study aimed to investigate the prevalence of SUI and the associated risk factors in a population of Chinese perimenopausal and postmenopausal women.

METHODS

A total of 273 perimenopausal and postmenopausal women were enrolled, and a cross-sectional study was conducted. SUI was defined as an involuntary loss of urine with increases in abdominal pressure. Data including personal characteristics, menopause information, estrogen levels, and pelvic floor muscle strength levels were statistically analyzed.

RESULTS

The study enrolled 158 (57.9%) perimenopausal and 115 (42.1%) postmenopausal women. Sixty-six (41.8%) perimenopausal women and 56 (48.7%) postmenopausal women complained of SUI. The mean age was 49.42 ± 5.58 years. Body mass index over 24 kg/m2 (odds ratio [OR] 2.02, 95% confidence interval [CI] 1.07-3.81), vaginal delivery (OR 2.47, 95% CI 1.33-4.58), and diabetes (OR 4.65, 95% CI 1.23-17.62) were high-risk factors for SUI. Climacteric symptoms (evaluated by Kupperman index scores) were statistically related to SUI, and among the 13 symptoms, insomnia, nervousness, weakness and fatigue, arthralgia and myalgia, headache, palpitation, and sexual complaints were all correlated with SUI in perimenopausal and postmenopausal women.

CONCLUSIONS

Several factors are associated with SUI in Chinese perimenopausal and postmenopausal women. Obesity, vaginal delivery, climacteric symptoms, and diabetes were identified as the most notable risk factors. The management strategy could focus on the prevention and management of risk factors.

One-year follow-up after standardized perineal reconstruction in women with deficient perineum after vaginal delivery

INTRODUCTION

Perineal tears are common after childbirth and, if not surgically repaired, they may result in a deficient perineum that can cause symptoms of pelvic floor dysfunction. Perineal reconstruction aims to restore the perineal body and increase the support of the pelvic floor. The objective of the present study was to estimate symptom reduction after perineal reconstruction in patients with deficient perineum after vaginal delivery and to compare outcomes between participants with or without concomitant levator ani muscle deficiency.

MATERIAL AND METHODS

Participants presenting at the Karolinska Pelvic Floor Center with symptoms of deficient perineum at least 1 year after vaginal birth were invited to the study. Inclusion criteria were a visible perineal scar and confirmed anatomic defect. Levator ani defects were assessed using the Levator Ani Deficiency score. A perineal reconstruction was performed in a standardized way. Subjective symptoms were evaluated using the validated "Karolinska Symptoms After Perineal Tear Inventory" at baseline and 1-year follow-up. A score difference in the symptom of an acquired sensation of a wide vagina was the primary outcome. Results were stratified by the presence or absence of a levator ani deficiency.

RESULTS

A perineal reconstruction was performed in 131 patients and 128 patients completed the Karolinska Symptoms After Perineal Tear Inventory at baseline and 119 at follow-up. Median age was 36.1 (interquartile range [IQR] 7.9), median body mass index 22.3 (IQR 5.1) and a median of two vaginal deliveries. Fifty-four women (41.2%) had a levator ani deficiency. The mean score reduction for the item "Do you feel that your vagina is too wide/loose?" was -1.56 (SD 0.96; P < 0.001) from a mean score of 2.75 (maximum 3) at baseline. The mean total score reduction was -9.1 points (SD 5.3; P < 0.001) from a mean score of 18.4 (maximum 33) points at baseline. There were no significant differences between groups when stratifying by levator ani deficiency.

CONCLUSIONS

Our results show that perineal reconstructive surgery significantly decreases symptoms of deficient perineum after vaginal delivery. A concomitant levator ani defect does not affect the symptom reduction of an acquired sensation of a wide vagina or the total score reduction after surgery.

Investigation of the relationship between sexual and pelvic floor dysfunction in female patients with fibromyalgia syndrome

The aim of the study was to examine the relationship between pelvic floor functions and sexual functions in women with fibromyalgia. The study included 204 women with fibromyalgia, mean aged 43.43 ± 8.61 years. All patients who met the inclusion criteria and applied to the rheumatology outpatient clinic were included in the study. The study was conducted between September 2020 and June 2022. The Female Sexual Function Scale (FSFI) was used to evaluate sexual function, Pelvic Floor Distress Scale-20 (PFDI-20), Pelvic Floor Impact Questionnaire (PFIQ-7) and Pelvic Organ Prolapse/Incontinence Sexual Function Assessment (PSIQ-12) were used to evaluate pelvic floor problems. The relationship between sexual dysfunction and other parameters was analyzed using Spearman correlation analysis. There was a weak negative correlation between many sub-parameters of FSFI and scores of PFDI-20, PFIQ-7, PSIQ-12 (r:-0.165--0.377 p: 0.02-0.00). According to the results of this study, sexual dysfunction was negatively affected by pelvic floor dysfunction and symptoms related to bladder, bowel, and pelvic organs in women with fibromyalgia. These results may suggest that sexual function and pelvic floor problems in women with fibromyalgia should be considered together and an approach should be planned for such problems in treatment programs.

Relationship Involving Sexual Function, Distress Symptoms of Pelvic Floor Dysfunction, and Female Genital Self-Image

OBJECTIVE

 To assess the relationship involving sexual function (SF), the distress symptoms caused by pelvic floor dysfunction (PFD), and female genital self-image (GSI).

MATERIALS AND METHODS

 We assessed the GSI, SF and PFD distress symptoms by the Female Genital Self-Image Scale (FGSIS), the Female Sexual Function Index (FSFI), and the Pelvic Floor Distress Inventory (PFDI-20) respectively. Data were analyzed by multiple linear regression.

RESULTS

 Among the 216 women (age: 50.92 ± 16.31 years) who participated in the study, 114 were sexually active in the previous 4 weeks. In the total sample (p < 0.001; adjusted R2 = 0.097) and among sexually active women (p = 0.010; adjusted R2 = 0.162), the distress symptoms caused by pelvic organ prolapse (POP) were related to the GSI. Among sexually active women, sexual desire also was related to the GSI (p < 0.001; adjusted R2 = 0.126).

CONCLUSION

 The findings of the present study provide additional knowledge about female GSI and suggest that SF and POP distress symptoms should be investigated together with the GSI in the clinical practice.

Three-dimensional endovaginal ultrasound assessment using the levator ani deficiency score in primiparas: A replication study

INTRODUCTION

It is essential to assess the levator ani properly as part of clinical care in patients presenting with pelvic floor dysfunction. The levator ani deficiency scoring system is a previously published method to assess levator ani defects with three-dimensional endovaginal ultrasound. The primary aim of this study was to determine the intra- and interrater reliability of the levator ani deficiency score in a cohort of non-instrumentally delivered primiparas.

MATERIAL AND METHODS

Primiparas (n = 141) were examined at least 1 year after vaginal birth. Three-dimensional endovaginal ultrasound volumes were acquired by a single examiner using two different automated ultrasound probes. The volumes were analyzed by two separate raters who were blinded to each other's assessments. Descriptive statistics were calculated for levator ani deficiency score and categorized into three levels (mild, moderate, severe). Kendall's tau-b was calculated for intra- and interrater comparisons.

RESULTS

Intrarater comparisons of levator ani deficiency score and levator ani deficiency category were high (Kendall's tau-b ≥0.80 for Rater 1; >0.79 for Rater 2). Interrater comparisons of levator ani deficiency score and levator ani deficiency category were also high (Kendall's tau-b >0.9 for assessment 1 and >0.78 for assessment 2). Varying by rater, probe and assessment, 75.9%-80.1% of the study population had no/mild deficiency, 6.4%-9.2% had moderate deficiency, and 4.3%-6.4% had severe levator ani deficiency.

CONCLUSIONS

The levator ani deficiency scoring system is a feasible method to assess defects of the levator ani muscle and can be reproduced with high intra- and interrater correlations. Using the scoring system in clinical practice may facilitate concordant assessment between different examiners. However, the system should be used to support clinical findings and symptomatology and not as a screening tool, as the score is lacking the category of no levator ani deficiency.

Therapeutic effect of the temperature-controlled radio frequency technology in female sexual dysfunction

OBJECTIVES

To explore the therapeutic effect of the temperature-controlled radiofrequency technology in female sexual dysfunction (FSD).

MATERIAL AND METHODS

From July 2020 to June 2021, patients with FSD who visited the Gynecology Clinic of Peking University Shenzhen Hospital were treated with the temperature-controlled radiofrequency technology once every two weeks, for a total of five times. The therapeutic effect was objectively evaluated with pelvic floor dysfunction (PFD) indicators (FSFI score, pelvic floor muscles surface electromyography, sexual function test). The pre- and post-treatment (2 weeks)/follow-up (3 months) results were compared to evaluate the feasibility of this technology for treating FSD, as well as using PFD-related indicators in objective evaluation of FSD patients.

RESULTS

Fifty patients completed treatment; 31 patients completed follow-up. The mean FSFI score for post-treatment/follow-up was significantly higher than pre-treatment (p < 0.05). There were no significant changes in the mean pelvic floor resting surface myoelectric potential and its variability and mean myoelectric potential of sexual function test between pre- and post-treatment/follow-up. The mean surface myoelectric potential of the patients' type I and II muscle fibers of the pelvic floor for post-treatment/follow-up was significantly higher than pre-treatment (p < 0.05). The mean peak myoelectric potential for post-treatment was significantly higher than pre-treatment (p < 0.05).

CONCLUSIONS

Temperature-controlled radiofrequency technology has a certain therapeutic effect on FSD. Pelvic floor surface electromyography and sexual function test can be used as an objective indicator for PFD in FSD patients. Subsequent studies may involve a larger size sample and evaluate the effect over a consecutive time-point, to develop a better therapeutic approach.

Effectiveness of Two Transcutaneous Electrical Nerve Stimulation (TENS) Protocols in Women with Provoked Vestibulodynia: A Randomized Controlled Trial

BACKGROUND

Vestibulodynia (VBD) is the most common form of vulvodynia. Because VBD is a pain disorder, transcutaneous electrical nerve stimulation (TENS) can be used as treatment. This study aims to evaluate the effects of two-parameter combinations (frequency and pulse duration) of TENS in reducing pain intensity and dyspareunia in VBD.

METHODS

A randomized, double-blind, controlled trial was conducted to study the effect of two different electrical stimulation treatment regimens on women with VBD receiving domiciliary TENS. Outcomes were the mean change from baseline at 60 and 120 days of burning/pain and dyspareunia (VAS), Vulvar Pain Functional Questionnaire (V-Q), Female Sexual Functioning Index (FSFI) and vaginal electromyography measurements.

RESULTS

A total of 78 subjects, 39 in each group, completed the trial. Patients in Groups 1 and 2 received a mean of 46.9 and 48.4 TENS sessions. By day 120, there was a 38.2% reduction in the burning/pain and a 52.1% reduction in the dyspareunia VAS scores in Group 1, as compared to 21.3% (p = 0.003) and 23.1% in Group 2 (p = 0.01), respectively. FSFI, V-Q, and muscle-strength measures also improved but were not statistically significant.

CONCLUSIONS

Our findings showed the potential of TENS in the treatment of VBD.

Ultrasonographic study of female perineal body and its supportive function on pelvic floor

Objectives

The study aimed to observe, measure the size and elastic value of perineal body (PB) and assess its association with levator hiatus.

Methods

Datasets were acquired in 45 nulliparous, 66 POP women and 70 postpartum women using ultrasound. The PB was measured in depth, height, and Young's modulus. The datasets were compared to assess whether there are some differences in the morphology, dimension and elastography modulus of PB among women. Pearson correlation analysis was used to evaluate the association between the morphology measurements (ΔValsalva-rest[v-r]), tissue mechanical properties (ΔValsalva-rest[v-r]) of the PB and levator hiatus area (ΔValsalva-rest[v-r]) to preliminarily explore whether PB can influence levator hiatus.

Results

Four representative manifestations of PB were presented in our study. Nulliparous women had smaller diameters and bigger Young's modulus while postpartum women had bigger diameters and smaller Young's modulus. POP and postpartum women had bigger levator hiatal distensibility and PB extensibility. There was no statistical association between PB measurements and levator hiatal area.

Conclusion

It is feasible to observe the morphology of PB and assess the dimension and elastography modulus by high-frequency ultrasound. The manifestations and measurements of PB are influenced by parity and long-term increased abdominal pressure. Our study preliminarily shows that PB has little effect on levator hiatus area.

Mid-Term Results of a New Transobturator Cystocele Repair by Vaginal Patch Plastron without Mesh

Cystoceles are the most common prolapses. Limitation of the use of synthetic mesh has led to the comeback of native tissue repair procedures. We have developed a new transobturator technique with native tissue based on a mix of a vaginal plastron technique and the transobturator procedure. We present the functional and anatomical mid-term results. In this retrospective study, the vaginal plastron technique and the transobturator procedure were performed in 32 patients. Functional assessment with several validated quality-of-life questionnaires (SF-12, PFIQ-7, PFDI-20, PISQ12) and anatomical evaluation with pelvic examination were performed at 1, 6, and 12 months after surgery. The anatomical success rate was 94.4% at 12 months. There was one Clavien-Dindo grade 2 postoperative complication (one urinary tract infection). All of the quality-of-life scores were statistically significantly improved at one year follow-up. The transobturator technique combined with the vaginal plastron seems to be a promising, effective, innovative, and relevant technique for the repair of high-stage cystoceles.

Long-Term Outcomes of Transanal Irrigation for Bowel Dysfunction

INTRODUCTION

Transanal irrigation (TAI) improves bowel function and quality of life in patients with neurogenic bowel disease compared to conservative bowel care. Its use has been extended to a range of defecatory disorders. However, data on long-term benefits and compliance are lacking. We aim to evaluate the long-term efficacy of TAI by examining compliance and patient outcomes over a five-year period.

METHODS

This study is a five-year retrospective review of patients practising TAI in a district general hospital. Patient demographics, indications, long-term compliance, adverse events, and patient-reported Qufora bowel symptom bother scores were analysed.

RESULTS

A cohort of 18 patients had a median age of 61 (range 23-91) and were predominantly female (83.5%). The reasons for bowel dysfunction were diverse: low anterior resection syndrome, neurogenic bowel, congenital anorectal malformations, obstructed defecation, and functional disorders. Predominant symptoms were constipation (9), faecal incontinence (7), and mixed (2). Both high-volume (catheter and cone) and low-volume (mini cone) irrigation devices were used. Fourteen patients continued regular irrigation at a median follow-up of 27.7 months (range 5.1-72.3), while four had discontinued at a median follow-up of 4.8 months. The reasons for discontinuation were inadequate rectal evacuation and spontaneous improvement of symptoms. In the compliant group, there was a significant improvement in bowel symptom scores (p=0.003). No major adverse events, such as significant rectal bleeding or perforation, were noted.

CONCLUSION

In this small cohort, TAI was safe and effective for long-term use; however, a fifth of patients discontinued treatment. Further work needs to be done to identify those patients who will benefit from TAI.

Preliminary study on mesenchymal stem cells in repairing nerve injury in pelvic floor denervation

Introduction: Nerve injury is considered one of the causes of pelvic floor dysfunction. Mesenchymal stem cells (MSCs) transplantation provides new possibilities for refractory degenerative diseases. This study aimed to explore the possibility and strategy of mesenchymal stem cells in treating pelvic floor dysfunction nerve injury. Methods: MSCs were isolated from human adipose tissue and cultured. A MSCs suspension (40 µL at 5 × 107/mL) was loaded on a gelatin scaffold. A rat model of anterior vaginal wall nerve injury was established by bilateral pudendal nerve denervation. The nerve tissue repair effect of mesenchymal stem cells transplanted into the anterior vaginal wall of a rat model was explored and compared in the following three groups: blank gelatin scaffold group (GS group), mesenchymal stem cell injection group (MSC group), and mesenchymal stem cells loaded on the gelatin scaffold group (MSC-GS group). Nerve fiber counting under a microscope and mRNA expression of neural markers were tested. Moreover, mesenchymal stem cells were induced into neural stem cells in vitro, and their therapeutic effect was explored. Results: Rat models of anterior vaginal wall nerve injury induced by bilateral pudendal nerve denervation showed a decreased number of nerve fibers in the anterior vaginal wall. qRT-PCR revealed that the content of neurons and nerve fibers in the rat model began to decrease 1 week after the operation and this could continue for 3 months. In vivo experiments showed that MSC transplantation improved the nerve content, and MSCs loaded on the gelatin scaffold had an even better effect. mRNA expression analysis demonstrated that MSCs loaded on gelatin scaffolds induced a higher and earlier gene expression of neuron-related markers. Induced neural stem cell transplantation was superior in improving the nerve content and upregulating the mRNA expression of neuron-related markers in the early stage. Conclusion: MSCs transplantation showed a promising repair capacity for nerve damage in the pelvic floor. The supporting role of gelatin scaffolds might promote and strengthen the nerve repair ability at an early stage. Preinduction schemes could provide an improved regenerative medicine strategy for innervation recovery and functional restoration in pelvic floor disorders in the future.

Identifying the risk factors and developing a predictive model for postoperative pelvic floor dysfunction in cervical cancer patients

Background

Pelvic floor dysfunction is a common complication after cervical cancer surgery, and the key to early prevention and treatment is the timely identification of risk factors and high-risk patients. The present study explored the risk factors of pelvic floor dysfunction in cervical cancer patients after surgery and established a predictive model.

Methods

A total of 282 cervical cancer patients admitted to Wuhan No.7 Hospital from January 2020 to June 2022 was retrospectively enrolled in this study. All patients underwent surgery and were followed up after surgery. The patients were divided into a pelvic floor dysfunction group (n=92) and a control group (n=190) according to whether they developed pelvic floor dysfunction or not at 6 months post-surgery. The differences in clinical features between the two groups were observed to identify the risk factors of pelvic floor dysfunction after cervical cancer, and a prediction model was established.

Results

There were significant differences in age, surgical method, surgical resection range, and radiotherapy between the two groups (P<0.05). Age greater than 65 years, open surgery, total hysterectomy, and radiotherapy were identified as the risk factors of postoperative pelvic floor dysfunction in patients with cervical cancer (P<0.05). The R4.0.3 statistical software was used to randomly divide the dataset into a training dataset (n=141) and a validation dataset (n=141). The area under the curve was 0.755 (95% confidence interval: 0.673-0.837) in the training set and 0.604 (95% confidence interval: 0.502-0.705) in the verification set. In the validation set, the model was tested with a Hosmer-Lemeshow Goodness-of-Fit test, with a chi-square value of 9.017 and a P value of 0.341.

Conclusions

Patients with cervical cancer have a high incidence of postoperative pelvic floor dysfunction. Age greater than 65 years, open surgery, total hysterectomy, and radiotherapy are risk factors of postoperative pelvic floor dysfunction in cervical cancer patients, and the present model helps to identify patients at high-risk of pelvic floor dysfunction.

Pelvic floor dysfunction and electrophysiology in postpartum women at 6-8 weeks

Objective: To investigate the incidence of pelvic floor dysfunction (PFD) and electrophysiological indicators in postpartum women at 6-8 weeks and explore the influence of demographic characteristics and obstetric factors. Methods: A survey questionnaire collected information about the conditions of women during their pregnancy and puerperal period and their demographic characteristics; pelvic organ prolapse quantitation (POP-Q) and pelvic floor muscle electrophysiology (EP) examination were conducted in postpartum women at 6-8 weeks. Results: Vaginal delivery was a risk factor for anterior pelvic organ prolapse (POP) (OR 7.850, 95% confidence interval (CI) 5.804-10.617), posterior POP (OR 5.990, 95% CI 3.953-9.077), anterior and posterior stage II POP (OR 6.636, 95% CI 3.662-15.919), and postpartum urinary incontinence (UI) (OR 6.046, 95% CI 3.894-9.387); parity was a risk factor for anterior POP (OR 1.397,95% CI 0.889-2.198) and anterior and posterior stage II POP (OR 4.162, 95% CI 2.125-8.152); age was a risk factor for anterior POP (OR 1.056, 95% CI 1.007-1.108) and postpartum UI (OR 1.066, 95% CI 1.014-1.120); body mass index (BMI) was a risk factor for postpartum UI (OR 1.117, 95% CI 1.060-1.177); fetal birth weight was a risk factor for posterior POP (OR 1.465, 95% CI 1.041-2.062); and the frequency of pregnancy loss was a risk factor for apical POP (OR 1.853, 95% CI 1.060-3.237). Conclusion: Pelvic floor muscle EP is a sensitive index of early pelvic floor injury. The changes in muscle strength and fatigue degree coexist in different types of postpartum PFD, and each has its own characteristics.

Pelvic Vascular Malformations and Recurrent Rectal Prolapse in a Patient With Maffucci Syndrome: A Diagnostic and Therapeutic Challenge

Maffucci syndrome is an extremely rare congenital condition characterized by the development of multiple enchondromas and haemangiomas, primarily on the extremities, and an association with various tumors. Colonic and pelvic floor function has never been explored in patients with Maffucci syndrome. We report a case illustrating the challenges in managing colonic and pelvic floor dysfunction in a female patient secondary to vascular malformations as part of Maffucci syndrome.

Women's sexual activity and experiences following female genital fistula surgery

BACKGROUND

Surgical repair has a transformative impact on the lives of women affected by female genital fistula; however, various physical, social, and economic challenges may persist postrepair and prevent complete reengagement in relationships and communities. Nuanced investigation of these experiences is needed to inform programming that aligns with women's reintegration needs.

AIM

We investigated the sexual activity resumption, experiences, and concerns of women in Uganda during the year following genital fistula repair surgery.

METHODS

Women were recruited from Mulago Hospital between December 2014 and June 2015. We collected data at baseline and 4 times postsurgery about sociodemographic characteristics and physical/psychosocial status; we also assessed sexual interest and satisfaction twice. We performed in-depth interviews with a subset of participants. We analyzed quantitative findings via univariate analyses, and qualitative findings were coded and analyzed thematically.

OUTCOMES

We assessed sexual readiness, fears, and challenges following surgical repair of female genital fistula using quantitative and qualitative measures of sexual activity, pain with sex, sexual interest/disinterest, and sexual satisfaction/dissatisfaction.

RESULTS

Among the 60 participants, 18% were sexually active at baseline, which decreased to 7% postsurgery and increased to 55% at 1 year after repair. Dyspareunia was reported by 27% at baseline and 10% at 1 year; few described leakage during sex or vaginal dryness. Qualitative findings showed wide variance of sexual experiences. Some reported sexual readiness quickly after surgery, and some were not ready after 1 year. For all, fears included fistula recurrence and unwanted pregnancy.

CONCLUSION

These findings suggest that postrepair sexual experiences vary widely and intersect meaningfully with marital and social roles following fistula and repair. In addition to physical repair, ongoing psychosocial support is needed for comprehensive reintegration and the restoration of desired sexuality.

HIGHLIGHTS

Defecatory disorders in patients with type 1 diabetes and chronic constipation

BACKGROUND AND OBJECTIVES

Chronic constipation (CC) may be caused by defecatory disorders (DDs) and associated with reduced rectal sensation. Among patients with type 1 diabetes (T1D) and CC (T1DCC patients), the prevalence of DDs and reduced rectal sensation is unknown. We sought to compare complications of T1D, anorectal dysfunction, and CC symptoms, among T1DCC patients with versus without a DD.

METHODS

Anorectal pressures at rest and during squeeze and evacuation, as well as rectal sensation and rectal balloon expulsion time (BET) were measured with high-resolution anorectal manometry in 114 consecutive T1DCC patients.

RESULTS

Thirty-seven patients (32%) had prolonged BET, suggestive of a DD. Complications of T1D included peripheral neuropathy (n = 67, 59%), retinopathy (n = 42, 37%), and nephropathy (n = 26, 23%). Among these complications, only retinopathy was associated with, that is, more prevalent in patients with normal (45%) than prolonged BET (19%). Compared with patients with normal BET, patients with prolonged BET had a lower rectal pressure (mean [SD], 32 [23] mm Hg vs. 23 [19] mm Hg, p = 0.03), greater anal pressure (91 [23] mm Hg vs. 68 [36] mm Hg, p < 0.001), and lower rectoanal gradient (-67 [30] mm Hg vs. -36 [32] mm Hg, p < 0.0001) during evacuation. Anal resting pressure and anal squeeze increment were below normal in 14 (13%) and 32 (29%) of patients and one or more rectal sensory thresholds were above normal in 34 (30%) patients; these abnormalities affected similar proportions in the normal and prolonged BET cohorts.

CONCLUSIONS

Among T1DCC patients, 37 (32%) had prolonged BET, which was associated with anorectal pressures indicative of a DD but was not associated with reduced rectal sensation, suggesting that DDs are more likely explained by abdomino-anal dyscoordination than visceral disturbance.

Work-Related Factors Associated With the Pelvic Floor Dysfunction Among a Sample of Female Nurses in China

BACKGROUND

Female nurses are a high-risk group for pelvic floor dysfunction (PFD). Predictors of female nurses' PFD among work-related factors are not well known. The aim of this study was to investigate the prevalence of PFD and its association with workplace conditions among female nurses in China.

METHODS

An online cross-sectional survey was conducted in May 2021. A sample of 380 registered nurses working in six tertiary hospitals in Nanjing, China participated. Data on individual characteristics, work-related factors, the Pelvic Floor Distress Inventory-20 and Pelvic Floor Impact Questionnaire-7 were used.

FINDINGS

The overall prevalence of PFD among nurses was 83.9%, with 43.9% of participants experiencing pelvic organ prolapse, 66.6% experiencing anorectal dysfunction and 60.5% experiencing lower urinary tract symptoms. In terms of work-related factors, PFD was associated with heavy lifting, pushing, and carrying at work, delayed toileting at work and fluid intake. Female nurses with PFD reported lower quality of life (QoL) relative to nurses without PFD.

CONCLUSIONS/APPLICATION TO PRACTICE

Our findings provide initial insights into workplace conditions that promote PFD among female nurses. Occupational health nurses should consider providing educational information for female workers who are potentially at risk for PFD and consider integrating screening of PFD into practice.

Childhood Sexual Abuse and Pelvic Floor Dysfunction in Midlife Women in the Study of Women's Health Across the Nation

Objectives: Research has shown a link between childhood sexual abuse (CSA) and lower urinary tract and sexual disorders in clinical settings. We examined whether CSA was associated with two specific aspects of high tone, elevated resting tension pelvic floor dysfunction (PFD) in community-dwelling women. Materials and Methods: Data were from 2068 participants (25.5% Black, 9.6% Chinese, 10.8% Japanese, 5.0% Hispanic, and 49.1% Non-Hispanic White) in the Study of Women's Health Across the Nation (SWAN), a multirace/multiethnic longitudinal observational study of women's midlife health. At baseline, enrolled women were 42-52 years old and premenopausal or early perimenopausal. Annual or biennial assessments conducted over 20 years (1996 through 2017) included single-item queries about urgency urinary incontinence and pain with sexual activity used to assess PFD outcomes. The 12th follow-up visit conducted in 2009-2011 assessed the primary exposure, history of CSA, using a single-item response. Multivariate logistic regression models tested study objectives. Results: The prevalence of CSA was 15%, self-reported in 313/2068 women. CSA and PFD, both pain with sexual activity (odds ratio [OR] = 1.56 confidence interval [95% CI = 1.12-2.18]) and urgency urinary incontinence (OR = 1.87 [95% CI = 1.29-2.71]), were significantly associated in unadjusted models. The final adjusted model that included sociodemographic variables and physical and behavioral risk factors was significant for pain with sexual activity (OR = 1.48 [95% CI = 1.08-2.02]), but not for urgency urinary incontinence (OR = 1.38 [95% CI = 0.96-1.98]). Conclusions: In midlife women, pain with sex, but not urgency urinary incontinence, was associated with a history of CSA. A multidisciplinary diagnostic and therapeutic approach to PFD is key, inclusive of CSA screening.

Pelvic Floor Disorders and Pelvic Floor Muscle Exercise: A Survey on Knowledge, Attitude, and Practice among Pregnant Women in Northwest Ethiopia

The purpose of the study was to investigate 1: overall knowledge of pelvic organ prolapse (POP) and urinary incontinence (UI) as well as knowledge, attitudes, and practice of pelvic floor muscle exercise (PFME); and 2: the association of these factors with parity in pregnant women in Gondar, Ethiopia. A facility-based cross-sectional study was performed in the Central Gondar zone, northwest Ethiopia between February and April 2021. The associations between parity and knowledge of POP and UI, and knowledge, attitude, and practice towards PFME were estimated using logistics regression models and presented as crude and adjusted odds ratios with 95% confidence intervals. Nulliparous women were used as the reference. Adjustments were made for maternal age, antenatal care visits, and level of education. The study sample comprised 502 pregnant women: 133 nulliparous, and 369 multiparous. We found no association between parity and knowledge of POP, UI, or knowledge, attitude, and practice toward PFME. The sum score indicated poor knowledge about both POP, UI, and PFME in the study population, and poor attitude and practice of PFME. Despite a high attendance in antenatal care services, knowledge, attitude, and practice were poor, indicating a need for quality improvement of the services.

The "Mother Load" and Return to Sport: A Case Report of Returning to Professional Netball Following Cesarean Section

Background

Increasing numbers of elite female athletes are competing in professional sport, and many wish to become pregnant and return to competitive sport after childbirth. Athletes have a higher risk of pelvic floor dysfunction (PFD) than non-athletes (54% versus 7%) and there is also an increased prevalence in post-partum women compared to nulliparous women (35% versus 2.8-7.9%). Additionally, PFD has been shown to influence athletic performance. High quality evidence for elite athletes is lacking, and there are no exercise guidelines specifically for these women to prepare or effectively guide their safe return to sport (RTS). The purpose of this case report is to detail the management of an elite athlete who presented following cesarean section (CS) with the goal of RTS within 16 weeks.

Case Description

A 27-year-old primiparous Caucasian professional netballer presented at four weeks post- caesarean section (CS) for RTS screening and assessment of pelvic floor muscle (PFM) function. Assessment included readiness and fear of movement screening, dynamic pelvic floor muscle function, structural integrity of the CS wound, levator hiatal dimensions, bladder neck descent, and early global neuromuscular screening. Measures were collected at four weeks, eight weeks, and six months post-partum. The post-partum athlete demonstrated alterations in pelvic floor muscle function, reduced lower limb power and psychological readiness. A functionally staged dynamic and sport specific pelvic floor muscle training program was implemented and adapted to the patient for her early post-partum timeline.

Results

Rehabilitation strategies were effective in achieving the primary outcome of RTS at 16 weeks post-partum with no adverse events reported at 6 months follow-up.

Discussion

This case highlights the need for a holistic and individualised RTS management approach that includes women's and pelvic health risk factors in a professional athlete.

Effect of the length of the second stage of labor on pelvic floor dysfunction

BACKGROUND

Pelvic floor dysfunction refers to any combination of incontinence, overactive bladder, pelvic organ prolapse, and sexual dysfunction. Pelvic floor dysfunction affects approximately 25% to 30% of women and is linked to parity and age. Some obstetrical risk factors have been highlighted, though the second stage of labor has not been as thoroughly investigated. Allowing a longer second stage has been suggested as a method of reducing the rates of cesarean delivery in nulliparous women, though it has also been linked to pelvic floor injuries.

OBJECTIVE

This study aimed to determine the effect of the length of the second stage of labor on self-reported pelvic floor dysfunction.

STUDY DESIGN

This was a single-center prospective cohort study in a tertiary referral obstetrical unit. Nulliparous women attending routine antenatal clinics were recruited to complete the Australian Pelvic Floor Questionnaire during pregnancy and again 3 months after delivery. The primary outcome in this study was the effect of the length of the second stage of labor on total pelvic floor scores when analyzed using multiple regression. The models were adjusted for the mother's age, mother's body mass index, length of the second stage of labor, fetal birthweight, mode of delivery, and perineal trauma. The secondary outcomes included the comparison of maternal, obstetrical, and functional pelvic floor outcomes based on the mode of delivery and the length of the second stage of labor.

RESULTS

Among the 295 women who were recruited, the length of the second stage of labor and body mass index were associated with self-reported bladder dysfunction on multiple regression, whereas maternal age was protective. Compared with those with 60 to 120 minutes or <60 minutes of second stage of labor, women with that longer than 120 minutes had higher rates of stress incontinence (85.7% [>120 minutes] vs 41.7% [60-120 minutes] or 52.5% [<60 minutes], P=.001), urinary urgency (89.3% [>120 minutes] vs 39.6% [60-120 minutes] or 53.8% [<60 minutes], P<.001), and fecal incontinence (10.7% [>120 minutes] vs 0% [60-120 minutes] or 1.2% [<60 minutes], P=.027). There were no differences in the rates of sexual activity or dyspareunia. Women delivering vaginally had higher rates of stress incontinence (57.6% vs 38.0%, P=.006) than those undergoing cesarean delivery, though there were no differences in other pelvic floor symptoms or pelvic floor scores.

CONCLUSION

A prolonged second stage of labor is associated with more self-reported bladder dysfunction at 3 months postnatal in primiparous women. Women with a longer second stage of labor should be informed about the risk of short-term bladder dysfunction, though the prevalence of long-term sequelae is unknown.

Colonoscopic findings in patients with pelvic floor dysfunction

BACKGROUNDY

Colonoscopy is often performed in the initial workup of pelvic floor dysfunction, even in the absence of red flag symptoms. Current guidelines suggest colonoscopy is only required in the presence of rectal bleeding, diarrhoea or change in bowel habit. The aim of this study was to evaluate the prevalence of significant pathology found at colonoscopy in patients with pelvic floor dysfunction.

METHODS

Retrospective chart review was performed on all patients presenting to a functional colorectal outpatient clinic between May 2018 and August 2019. Information was collected on presenting symptoms, whether colonoscopy had been performed within 5 years, quality of bowel preparation, withdrawal time, number of polyps detected, histology, presence of diverticular disease, colorectal malignancy, inflammatory bowel disease, solitary rectal ulcer or rectal prolapse.

RESULTS

There were 260 patients seen within the study period, of which 67% had undergone recent colonoscopy within the last 5 years. The mean age was 53 and 219 (84%) patients were female. Average withdrawal time was 13 min. Polyps were found in 48.7% and adenomas in 32.4% of all colonoscopies. The adenoma detection rate was 32.7%. None of the colonoscopies found evidence of malignancy. A new diagnosis of inflammatory bowel disease was discovered in two patients.

CONCLUSION

There was low rates of serious pathology such as malignancy or inflammatory bowel disease in patients referred to a functional clinic. However, colonoscopy is still useful in workup of pelvic floor dysfunction, as many patients have erratic bowel habits or vague symptoms, and will have adenomas found.

Association of lower extremity lymphedema with pelvic floor functions, sleep quality, kinesiophobia, body image in patients with gynecological cancers

The aim was to investigate the relationship between lower extremity lymphedema and pelvic floor functions, sleep quality, kinesiophobia, body image in patients with gynecological cancer the effect of lymphedema severity on pelvic floor dysfunction (PFD), sleep quality, fear of movement, and body image in patients with lower extremity lymphedema after gynecologic cancer. A total of 103 patients (52 patients with lymphedema and 51 patients without lymphedema) after gynecologic cancer surgery were included in March-June 2022. Bilateral circumferential measurements were taken with a tape measure at different levels to create groups. These measurements determined limb volumes by summing segment volumes derived from the truncated cone formula. For data collection, all patients were presented with the Gynecologic Cancer Lymphedema Questionnaire (GCLQ), the Global Pelvic Floor Bother Questionnaire (GPFBQ), the Pittsburgh Sleep Quality Index (PSQI), the Tampa Scale of Kinesiophobia (TSK) and the Body Image Scale (BIS) one time. The severity of lymphedema symptoms was quite high in patients with lymphedema (GCLQ Total: 13.6) (p < .05). Patients with lymphedema had higher GCLQ total scores, GPFBQ1 (stress urinary incontinence), GPFBQ4 (urge urinary incontinence), GPFBQ8 (fecal incontinence), kinesiophobia and, body image scores than patients without lymphedema (p < .05). The sleep quality levels of patients with lymphedema and patients without lymphedema were similar (p > .05). A significant negative correlation was found between GLCQ total score and body image (p < .05). There was a positive correlation between kinesiophobia and pelvic floor symptoms and a negative correlation between kinesiophobia and body image (p < .05). In this study, it was observed that in patients who developed lymphedema after gynecologic cancer surgery, pelvic floor symptoms and kinesiophobia increased and the severity of lymphedema negatively affected body image. Reducing lymphedema in these patients may improve pelvic floor health, mobility, and body image.

Rumba Dance Combined with Breathing Training as an Exercise Intervention in the Management of Stress Urinary Incontinence in Postmenopausal Women: A Randomized Controlled Trial

Purpose: Stress urinary incontinence (SUI) refers to involuntary leakage from the urethra, synchronous with exertion/effort, sneezing or coughing, which has a negative effect on quality of life. Studies have shown that mild-to-moderate physical activities reduce the risk of SUI by multiple mechanisms. The objective of this study was to determine whether the Rumba dance combined with breathing training (RDBT) can reduce the severity of incontinence and improve the quality of life of patients with SUI. Methods: A randomized clinical trial was conducted with women who were sedentary, were postmenopausal, reported mild-to-moderate SUI on a 1-h pad test, were not already engaged in Rumba dance and did not receive estrogen replacement therapy. The patients were randomly assigned to the RDBT group (n = 13) or the control group (n = 11). The intervention included 90 min of RDBT three times per week for 16 weeks, and the vaginal resting pressure (VRP), pelvic floor muscle (PFM) strength and endurance, 1-h pad test, International Consultation on Incontinence Questionnaire—Urinary Incontinence Short Form (ICIQ—UI SF), and the Incontinence Quality of Life Questionnaire (I—QOL) were measured or completed at baseline and 16 weeks. None of the participants reported adverse events. Results: The mean (±SD) age of the participants was 55.75 ± 5.58 years. After 16 weeks, in the RDBT group, the urine leakage on the 1-h pad test was significantly decreased −2.91 ± 0.49 from the baseline (p = 0.000). The VRP increased from 76.00 ± 16.23 cmH2O to 95.09 ± 18.90 cmH2O (p = 0.000), the PFM endurance of class I (−3.15 ± 1.99% vs. −0.46 ± 0.97%, p = 0.000) and class II (−0.69 ± 0.95% vs. −0.23 ± 0.44%, p = 0.065) increased, and the grades of PFM strength of class I and class II were significantly enhanced (p < 0.01). Finally, the severity of self-reported incontinence (ICIQ—UI SF) significantly decreased from 6.12 ± 2.15 to 3.81 ± 1.68 (p = 0.000), and quality of life (I—QOL) improved from 75.73 ± 11.93 to 83.48 ± 7.88 (p = 0.005). Conclusion: A 16-week RDBT program can increase PFM strength and endurance to reduce the severity of incontinence symptoms and improve the quality of life in patients with SUI, demonstrating the feasibility of recruiting and retaining postmenopausal women with SUI into a RDBT therapeutic program.

Reproducibility of high-resolution manometry among healthy and constipated persons

BACKGROUND AND AIMS

Although high-resolution manometry (HR_ARM) is commonly used to diagnose defecatory disorders, its intraindividual day-to-day reproducibility is unknown. Since these measurements entail voluntary effort, this study aimed to evaluate the intraindividual day-to-day reproducibility of HR_ARM.

METHODS

In 22 healthy women (35 years [14] mean [SD]) and 53 constipated patients (42 years [13], 46 women), the rectal balloon expulsion time (BET), and anorectal pressures were measured with HR_ARM on 2 days separated by a median (interquartile range) of 15 days (11-53) in healthy and 40 days (8-75) in constipated patients. Anorectal pressures were evaluated at rest (20 s), during squeeze, and during evacuation. Rectal sensation was also evaluated in constipated patients. The agreement between both measurements was evaluated with Lin's concordance correlation coefficient (CCC) and other tests.

RESULTS

Among constipated patients, the anal resting (mean CCC [95%CI] 0.62 [0.43-0.76]) and squeeze pressures (CCC 0.65 [0.47-0.79]), rectoanal gradient during evacuation (CCC 0.42 [0.17-0.62]), and rectal sensory thresholds (CCC for urgency 0.72 [0.52-0.84]) were concordant. Between days 1 and 2, one or more outcomes, characterized as normal or abnormal, differed in 79% of constipated patients, i.e., anal resting and squeeze pressures, the gradient, and the rectal BET differed in, respectively, 25%, 19%, 36%, and 10% of constipated patients. The rectal BET was prolonged in three healthy persons (both days) and either on 1 day (six patients) or 2 days (33 patients) in constipated patients.

CONCLUSIONS

While HR_ARM variables and the BET are reproducible within healthy and constipated persons, the outcome on repeat testing differed in 79% of constipated patients.

Three-dimensional ultrasound assessment of risk factors for cystocele and Green classification in primipara

BACKGROUND AND AIMS

The present study aimed to analyze the effects of factors on cystocele and the Green classification.

MATERIALS AND METHODS

We conducted a cross-sectional study on 357 primiparous women examined at our hospital from January 2019 to May 2021. The following data were recorded: maternal characteristics, neonatal characteristics, and factors of childbirth. It was added to the multivariate logistic regression model to determine the independent predictors of the cystocele and the Green classification.

RESULTS

A total of 242 women had cystocele, including 71 women with Green type I cystocele, 134 women with Green type II cystocele, and 37 women with Green type III cystocele. In multivariate logistic regression analysis, body mass index (BMI) at delivery was associated with cystocele, while BMI at delivery and the second stage of labor (SSL) > 1 h were independently with the distance from the symphysis pubis to the bladder neck (SPBN) abnormal (P < 0.05). BMI at examination was associated with the large retrovesical angle (RVA) (P < 0.05). BMI at delivery and the fetal right occiput anterior position (ROA) were independently associated with the distance from the symphysis pubis to the posterior wall of the bladder (SPBP) abnormal (P < 0.05), while epidural anesthesia (EDA) was the protective factor (P < 0.05).

CONCLUSION

Primipara women should strive to avoid exposure to modifiable risk factors such as controlling weight during pregnancy, reducing weight after delivery, and shortening SSL to reduce the occurrence of cystocele.

Pulsed Magnetic Stimulation for Stress Urinary Incontinence and Its Impact on Sexuality and Health

It is becoming increasingly common that patients' preferences move towards non-surgical approaches, such as pulsed magnetic stimulation, for female stress urinary incontinence.

OBJECTIVE

We evaluated the efficacy and safety of a device that uses electromagnetic technology to treat urinary incontinence, with an emphasis on health-related quality of life.

METHODS

A total of 47 female subjects from 18 to 80 years old were enrolled. After block randomization, treatment consisted of 2 pulsed planar magnetic stimulation sessions per week for 4 weeks (8 sessions). Validated questionnaires: Female Sexual Function Index, International Consultation on Incontinence Questionnaire for Urinary Incontinence: Short Form, and Pelvic Floor Bothersome. Follow-ups were performed at weeks 1, 9, and 14.

RESULTS

The present study is one of the first clinical trials published evaluating the efficacy and safety of the electromagnetism-based device with flat configuration in patients with stress urinary incontinence, showing a reduction in PFBQ, ICQSF, and Oxford test scores during follow-up, and significantly at week 14 of follow-up, which implied a favorable impact on clinical outcomes, quality of life, and sexuality.

CONCLUSIONS

The improved results in the treatment group compared with the simulated group show that pulsed magnetic stimulation is a safe and attractive non-invasive alternative for patients who prefer non-surgical treatments.

Automated extraction of anorectal pressures from high-resolution manometry reports

BACKGROUND

During high-resolution anorectal manometry (HR_ARM), the raw data are converted into software-derived summary variables (e.g., rectoanal gradient during evacuation) that capture only a snapshot of the data collected during HR_ARM and are less useful than newer indices, which are also derived from the raw data, for diagnosing defecatory disorders (DD). However, it is cumbersome and time-consuming to extract raw data from the program and calculate such indices. This study aimed to devise a user-friendly approach to extract anorectal pressures measured with HR_ARM.

METHODS

Anorectal pressures at rest, during anal squeeze, and evacuation were measured with HR_ARM in 180 women, among whom 60 each were healthy, had DD, or fecal incontinence. A reverse engineering approach extracted pressure values from color images in HR_ARM reports. The summary variables generated by the software and a reverse engineering approach were compared with Lin's concordance correlation coefficient (CCC), paired t-tests, and Bland-Altman's tests.

RESULTS

Anorectal pressures summarized by the software and a reverse engineering method were highly concordant for anal resting (CCC [95% CI], 0.98 [0.97, 0.99]) and squeeze pressures (0.99 [0.99, 0.99) and the rectoanal gradient during evacuation with an empty (0.98 [0.97, 0.98]) and a filled balloon (0.99 [0.99, 0.99]). For most variables, the paired t and Bland-Altman comparisons were not significant.

CONCLUSIONS

Anorectal pressures can be accurately determined from pressure topography images in HR_ARM reports. In future, this reverse engineering approach can be harnessed to compile large HR_ARM datasets across centers and to uncover newer, potentially more useful summary rectoanal pressure variables.

Bladder pain syndrome/interstitial cystitis response to nerve blocks and trigger point injections

Objectives

Bladder pain syndrome (BPS)/interstitial cystitis (IC) is a debilitating condition characterised by bladder/pelvic pain and pressure as well as persistent or recurrent urinary symptoms in the absence of an identifiable cause. It is hypothesised that in addition to organ specific visceral hypersensitivity, contributions of the hypertonic pelvic floor, peripheral sensitisation, and central sensitisation exacerbate this condition. The aim of this paper is to investigate outcomes of treating underlying neuromuscular dysfunction and neuro-plastic mechanisms in BPS/IC patients.

Methods

A retrospective chart review of 84 patients referred to an outpatient pelvic rehabilitation centre with a diagnosis of BPS/IC given to them by a urologist. All 84 patients failed to progress after completing 6 weeks of pelvic floor physical therapy and underwent an institutional review board approved protocol (IRB# 17-0761) consisting of external ultrasound-guided trigger point injections to the pelvic floor musculature, peripheral nerve blocks of the pudendal and posterior femoral cutaneous nerves and continued pelvic floor physical therapy once weekly for 6 weeks. Pelvic pain intensity and functionality were measured pretreatment and 3 months posttreatment using Visual Analogue Scale (VAS) and Functional Pelvic Pain Scale (FPPS).

Results

Pretreatment, mean VAS was 6.23 ± 2.68 (95% CI 5.65 to 6.80). Posttreatment mean VAS was 3.90 ± 2.63 (95% CI 3.07-4.74). Mean FPPS before treatment was 11.98 ± 6.28 (95% CI 10.63 to 13.32). Posttreatment mean FPPS was 7.68 ± 5.73 (95% CI 6.45-8.90). Analysis of subcategories within FPPS indicated highest statistically significant improvement in the categories of bladder, intercourse and working.

Conclusions

Analysis suggests the treatment was effective at ameliorating bladder pain and function including urinary urgency, frequency, and burning in BPS/IC patients.

Optimizing techniques for measuring anal resting and squeeze pressures with high-resolution manometry

BACKGROUND

The optimal methods for measuring and analyzing anal resting and squeeze pressure with high-resolution manometry (HRM) are unclear.

METHODS

Anal resting and squeeze pressures were measured with HRM in 90 healthy women, 35 women with defecatory disorders (DD), and 85 with fecal incontinence (FI). Pressures were analyzed with Manoview™ software and a customized approach. Resting pressures measured for 20, 60, and 300 s were compared. During the squeeze period, (3 maneuvers, 20 s each), the squeeze increment, which was averaged over 5, 10, 15, and 20 s, and squeeze duration were evaluated.

RESULTS

Compared to healthy women, the anal resting pressure, squeeze pressure increment, and squeeze duration were lower in FI (p ≤ 0.04) but not in DD. The 20, 60, and 300 s resting pressures were strongly correlated (concordance correlation coefficients = 0.96-0.99) in healthy and DD women. The 5 s squeeze increment was the greatest; 10, 15, and 20 s values were progressively lower (p < 0.001). The squeeze pressure increment and duration differed (p < 0.01) among the three maneuvers in healthy and DD women but not in FI women. The upper 95th percentile limit for squeeze duration was 19.5 s in controls, 19.9 s in DD, and 19.3 s in FI. Adjusted for age, resting pressure, and squeeze duration, a greater squeeze increment was associated with a lower risk of FI versus health (OR, 0.96; 95% CI, 0.94-0.97).

CONCLUSIONS

These findings suggest that anal resting and squeeze pressures can be accurately measured over 20 s. In most patients, one squeeze maneuver is probably sufficient.

Effect of Pelvic Floor Workout on Pelvic Floor Muscle Function Recovery of Postpartum Women: Protocol for a Randomized Controlled Trial

BACKGROUND

There is a risk of pelvic floor dysfunction (PFD) from baby delivery. Many clinical guidelines recommend pelvic floor muscle training (PFMT) as the conservative treatment for PFD because pelvic floor muscles (PFMs) play a crucial role in development of PFD. However, there is disagreement about the method and intensity of PFM training and the relevant measurements. To pilot the study in PFM training, we designed a Pelvic Floor Workout (PEFLOW) for women to train their pelvic through entire body exercises, and we planned a trial to evaluate its effectiveness through comparing the outcomes from a group of postpartum women who perform PELFLOW at home under professional guidance online with the control group.

METHODS/DESIGN

The randomized controlled trial was projected to be conducted from November 2021 to March 2023. A total of 260 postpartum women would be recruited from the obstetrics departments of the study hospital and women would be eligible for participation randomized into experimental or control groups (EG/CG) if their PFM strength are scaled by less than Modified Oxford grading Scale (MOS) to be less than grade 3. Women in EG would perform a 12-week PEFLOW online under the supervision and guidance of a physiotherapist, while women in CG would have no interventions. Assessments would be conducted at enrollment, post intervention (for EG) or 18th to 24th week postpartum (for CG), and 1 year postpartum. Assessment would be performed in terms of pelvic floor symptoms, including MOS, cough stress test, urinary leakage symptoms, pelvic organ prolapse quantitation (POP-Q), and vaginal relaxation, clinic examinations including Pelvic floor electrophysiological test, Pelvic floor ultrasound and Spine X-ray, overall body test including trunk endurance test, handgrip test, body composition test, and questionnaires including International Physical Activity Questionnaire Score-Short Form(IPAQ-SF), Pelvic Floor Distress Inventory Questionnaire-20 (PFDI-20), Pelvic Floor Impact Questionnaire-7 (PFIQ-7), the 6-item Female Sexual Function Index (FSFI-6), and the Pittsburgh Sleep Quality Index (PSQI). Primary analysis will be performed to test our main hypothesis that PEFLOW is effective with respect to strengthen PFM strength.

DISCUSSION

This trial will demonstrate that pelvic floor-care is accessible to most women and clinical practice on PFD may change relevantly should this study find that Online PEFLOW approach is effective to improve PFMs.

Application of Transperineal Pelvic Floor Ultrasound in Changes of Pelvic Floor Structure and Function Between Pregnant and Non-Pregnant Women

Objective

To evaluate the changes of pelvic floor tissue structure and function between pregnant and non-pregnant women from the view of transperineal pelvic floor ultrasound.

Methods

Thirty-eight cases of women with a second singleton pregnancy and thirty-two cases of women with a first singleton pregnancy underwent transperineal pelvic floor ultrasound, and their results were compared with forty-two cases of healthy non-pregnant women.

Results

The differences of bladder neck descent (BND), rectal ampulla distance and levator hiatus area (LHA) among the three groups were statistically significant (P<0.05), and the differences of BND, rectal ampulla distance, LHA between the women with a second singleton pregnancy group and non-pragnent group were statistically significant (P<0.05). The BND, retrovesical angle at rest (RVA-R) and retrovesical angle underwent Valsalva maneuver (RVA-V) in the group of stress urinary incontinence (SUI) during pregnancy were larger than those in non-SUI group, with significant difference (P<0.05), especially BND and RVA-V (P = 0.00).

Conclusion

Transperineal pelvic floor ultrasound has a high resolution of pelvic floor structure and function changes during pregnancy, and can dynamically evaluate pelvic floor function, providing a theoretical basis for early diagnosis and prevention of female pelvic floor dysfunction (FPFD) in subsequent pregnancies.

Hypermobile Ehlers-Danlos syndrome and disorders of the gastrointestinal tract: What the gastroenterologist needs to know

BACKGROUND AND AIM

Hypermobile Ehlers-Danlos syndrome (hEDS) and the hypermobility spectrum disorders (HSD) can be challenging to diagnose and manage. Gastrointestinal symptoms and disorders of gut-brain interaction are common in this cohort and multifactorial in origin. The primary aim of this review is to arm the gastroenterologist with a clinically useful understanding of HSD/hEDS, by exploring the association of gastrointestinal disorders with HSD/hEDS, highlighting current pathophysiological understanding and providing a pragmatic approach to managing these patients.

METHODS

Literature relevant to the gastrointestinal system and hypermobile Ehlers-Danlos syndrome was systematically searched, critically appraised, and summarized.

RESULTS

Diagnosis is based upon clinical criteria and a genetic basis is yet to be defined. The prevalence of many gut symptoms, including abdominal pain (69% vs 27%, P < 0.0001), postprandial fullness (34% vs 16%, P = 0.01), constipation (73% vs 16%, P < 0.001), and diarrhea (47% vs 9%, P < 0.001) are significantly higher in HSD/hEDS compared with non-HSD/hEDS individuals. Disorders of gut-brain interaction are also common, particularly functional dyspepsia. The pathophysiology of gut symptoms is poorly understood but may involve effects of connective tissue laxity and its functional consequences, and the influence of autonomic dysfunction, medication and comorbid mental health disorders. Awareness is the key to early diagnosis. Management is limited in evidence-base but ideally should include an integrated multidisciplinary approach.

CONCLUSIONS

HSD/hEDS is a multisystemic disorder in which gastrointestinal symptoms, particularly related to disorders of gut-brain interaction are common. Deficiencies in knowledge regarding the pathophysiological processes limit evidence-based interventions and remain important areas for future research.

Effects of external electrical stimulation added to pelvic floor muscle training in women with stress urinary incontinence: A randomized controlled study

OBJECTIVE

In this study, the combination of external electrical stimulation (EES) with pelvic floor muscle training (PFMT) was assessed to determine if it yielded better results than PFMT or EES alone for treatment of stress urinary incontinence (SUI).

STUDY DESIGN

Fifty-one women with SUI were randomly allocated to EES + PFMT (n = 17), PFMT (n = 17), or EES groups (n = 17) for 8 weeks of treatment. Personal, demographic, and clinical characteristics of the patients were recorded. Outcome measures included self-reported improvement, severity of incontinence, symptom distress, quality of life (QOL), urinary incontinence episodes, pelvic floor muscle strength (PFMS) and endurance (PFME) and dysfunction. All evaluations were made pre- and posttreatment. Data were analyzed using the Chi-square, marginal homogeneity, Kruskal-Wallis, Wilcoxon signed-rank or paired t test and Dunn-Bonferroni post hoc tests.

RESULTS

In the 8th week, there were significant changes in self-reported improvement, severity of incontinence, symptom distress score, urinary incontinence episodes, PFMS, PFME, pelvic floor dysfunction and all areas of QoL in all groups (p < 0.05). Combined therapy was not superior to PFMT and EES for overall outcome measures, except for the incontinence impact subdomain of the QoL score (p < 0.05).

CONCLUSIONS

Our study supports the idea that PFMT should be preferred as the first line therapy for women with SUI. However, the acceptable EES method can be recommended in addition to PFMT to increase motivation and treatment compliance in patients with insufficient or inaccurate pelvic floor muscle contractions.

Pelvic floor symptoms from first pregnancy up to 8 years after the first delivery: a longitudinal study

BACKGROUND

Despite the strong association between vaginal childbirth and pelvic floor dysfunction, genetic factors, pregnancy, advancing age, and lifestyle also play a role. The pelvic floor undergoes substantial changes during pregnancy which may contribute to pelvic floor dysfunction. On the other hand, these changes may be favorable to allow for vaginal delivery. However, there is a lack of studies assessing pelvic floor symptoms over time according to delivery mode, which includes women prior to delivery.

OBJECTIVE

The aim of this study was to describe urinary incontinence, vaginal symptoms, and bowel control symptoms from 21 weeks of gestation in the first pregnancy and up to 8 years after the first delivery, stratified by delivery mode.

STUDY DESIGN

This is a longitudinal observational cohort study. 300 nulliparous women were recruited during their first pregnancy. Pelvic floor symptoms were assessed at 21 and 37 weeks of gestation, and 6 weeks, 6 months, 12 months and 8 years after first delivery using the International Consultation on Incontinence Questionnaire (ICIQ) modules: the urinary incontinence sum score; the weighted vaginal symptom sum score; the vaginal-associated quality of life score; the bowel control sum score; and the bowel-associated quality of life sum score. Delivery mode at first delivery defined delivery groups as: normal vaginal, operative vaginal and cesarean delivery. A linear mixed model analysis was used to assess symptom scores over time and to assess the differences in symptom scores between the delivery groups.

RESULTS

Of the 300 women included in the study, of which 193 attended the 8-year follow-up. Pelvic floor symptoms differed in women with vaginal and cesarean delivery. The symptom scores showed a non-linear statistically significant trend. In women, who delivered vaginally, there was an increase of urinary incontinence and vaginal symptom scores already during pregnancy. In women, who later delivered by cesarean, there was a decrease of symptoms scores during pregnancy, and overall lower symptom scores compared to women with vaginal delivery until 12 months after first delivery. Pelvic floor symptoms scores increased from 12 months to 8 years after the first delivery and exceeded pregnancy levels in all delivery groups, however overall symptom scores were low. Differences between delivery groups were not statistically significant.

CONCLUSION

Pelvic floor symptoms differed in women with vaginal and cesarean delivery from the first pregnancy up to 8 years after the first delivery. These differences were recognizable already prior to first delivery.

A Practical Approach to the Diagnosis and Treatment of Abdominal Bloating and Distension

Abdominal bloating and distension are highly prevalent symptoms that can negatively impact quality of life and lead to medical consultation. Despite their prevalence, symptoms of bloating and distension pose a unique diagnostic and therapeutic challenge, as they are inherently nonspecific symptoms with a complex etiology, and no uniform diagnostic or treatment algorithm currently exists. Additionally, bloating is common among disorders of gut-brain interaction, which can be difficult to treat. This article offers a practical approach for evaluating and treating symptoms of bloating and distension through discussion of 5 common etiologies: diet, small intestinal bacterial over-growth, constipation, visceral hypersensitivity, and abdomino-phrenic dyssynergia. An effective personalized evaluation and treatment plan can be established to address symptoms of bloating and distension through consideration of these etiologies in the context of the patient's individual characteristics and presentation.

Pelvic floor dysfunction at transperineal ultrasound and chronic constipation in women with endometriosis

OBJECTIVE

To assess the association between sonographic findings at transperineal ultrasound (TPU) and chronic constipation (CC) in women with endometriosis.

METHODS

An observational prospective cohort study was performed by enrolling all endometriosis women scheduled for surgery between September 2019 and October 2020. Women underwent TPU at rest and during Valsalva maneuver evaluating levator-hiatal-area (LHA), antero-posterior diameter (APD), levator-ani muscle (LAM)-coactivation. Ultrasound findings were compared between women with and without CC in the whole study population, and subsequently in two subgroups [only ovarian and deep infiltrating endometriosis (DIE)].

RESULTS

87 women were enrolled: 29 (33%) with CC and 58 (67%) without CC. Women with endometriosis and CC showed a smaller LHA during Valsalva, less LHA and APD enlargement from rest to maximum Valsalva, a higher prevalence of LAM-coactivation compared to women without CC. In ovarian-subgroup, women with CC had smaller LHA at Valsalva, less enlargement of LHA and APD from rest to maximum Valsalva and higher prevalence of LAM-coactivation compared to non-CC patients. In DIE-subgroup, TPU did not significantly differ between CC and non-CC patients.

CONCLUSION

TPU signs of pelvic floor muscle hypertone are more frequent in endometriosis patients with CC compared to those without constipation, particularly in women affected by isolated ovarian endometriosis.
