Prevalence and associated factors of symptomatic pelvic floor disorders among women living in Debre Tabor Town, Northwest Amhara, Ethiopia. BMC Womens Health 2024; 24:367. [PMID: 38915020 PMCID: PMC11194954 DOI: 10.1186/s12905-024-03176-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Accepted: 05/30/2024] [Indexed: 06/26/2024] Open
Abstract
BACKGROUND Pelvic floor disorders are a group of disorders affecting the pelvic floor that include clinically definable conditions such as pelvic organ prolapse, urinary incontinence and fecal incontinence. These conditions silently affect millions of women worldwide and related problems are not well disclosed by women due to associated social stigma or lack of access to services in developing countries. Thus, the magnitude and related burden of these conditions vary, and little is known about them. This study was conducted to assess the magnitude and associated factors of symptomatic pelvic floor disorders in Debre Tabor town, Northwest, Ethiopia, from May 30-July 30, 2020. METHOD A community-based cross-sectional study was conducted on child bearing women (> 15 years) who resided in Debre Tabor Town from May 30-July 30, 2020. The participants were selected through multistage systematic random sampling. The data were collected via a structured questionnaire through face-to-face interviews, entered into Epi-info-7.2, and subsequently analyzed using SPSS version 20. The prevalence of pelvic floor disorders was presented along with the 95% CI. RESULTS A total of 402 women participated in this study, 59 (14.7%; 95% CI; 11.4, 18.2) of whom reported one or more types of pelvic floor disorders. The most prevalently reported pelvic floor disorders were pelvic organ prolapse (13.9%; 95% CI: 10.9, 17.4), urinary incontinence (10.9%; 95% CI: 7.4, 9.2) and fecal incontinence (7.7%; 95% CI: 5.2, 10.2). Additionally, aging, multiparity and having early marriage (< 18 yrs.) were identified as potential risk factors associated with pelvic floor disorders. CONCLUSIONS The prevalence of symptomatic pelvic floor disorders in the current study was high. Thus, early detection, preventive and treatment strategies should be considered. In addition, it is better to educate the community and women on the association of early marriage and multiparty with PFDs.

From thigh to pelvis: female genital prolapse repair with an autologous semitendinosus tendon transplant : Data of the German multicenter trial. Int Urogynecol J 2023; 34:2373-2380. [PMID: 37129627 PMCID: PMC10590289 DOI: 10.1007/s00192-023-05512-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Accepted: 02/22/2023] [Indexed: 05/03/2023]
Abstract
INTRODUCTION AND HYPOTHESIS The use of synthetic mesh for prolapse and incontinence surgery is discussed controversially and in several countries is either no longer used or permissible. Previous approaches with autologous tissue did not show from a patient´s perspective convincing long-term results. As there have been repeatedly significant complications with synthetic mesh, a new approach is urgently needed. During orthopedics and trauma surgeries, tendons from the thigh have been used for decades to replace cruciate ligament. The procedure of tendon removal from the thigh is fast, easy to learn and morbidity is low. In addition, a long-term durability of the transplant ought to be expected. The objective of this investigation was to show our experience with a semitendinosus tendon instead of a mesh for genital prolapse repair. METHOD After the first successful attempts using such tendons in cervicosacropexy and pectopexy in patients with genital prolapse, we initiated a national multicenter study in 2020. Five German hospitals participated in order to determine the feasibility of cervicosacropexy with tendon tissue instead of mesh. RESULT Up until now, we have operated and observed 113 patients for at least 6 months and have seen stable results in terms of fixation of the apical compartment. The expected low morbidity at the donor site was also confirmed through subjective assessment of the patients (Knee and Osteoarthritis Outcome Score). Improvement of quality of life was confirmed after the procedure with the Short Form Health Survey 12, Version 2.0. The results of this multicenter study showed that the desired elevation of the apical compartment with tendon tissue can be achieved with low morbidity and without a synthetic mesh. CONCLUSION Women with uterine prolapse can be treated minimally invasively and with very low morbidity by using the semitendinosus tendon. The involvement of multiple (five) medical centers confirms that the technique is easy to learn and be transferred to other clinical centers.

Supramolecular Fibrous Hydrogel Augmentation of Uterosacral Ligament Suspension for Treatment of Pelvic Organ Prolapse. Adv Healthc Mater 2023; 12:e2300086.

Abstract
Uterosacral ligament suspension (USLS) is a common surgical treatment for pelvic organ prolapse (POP). However, the relatively high failure rate of up to 40% underscores a strong clinical need for complementary treatment strategies, such as biomaterial augmentation. Herein, the first hydrogel biomaterial augmentation of USLS in a recently established rat model is described using an injectable fibrous hydrogel composite. Supramolecularly-assembled hyaluronic acid (HA) hydrogel nanofibers encapsulated in a matrix metalloproteinase (MMP)-degradable HA hydrogel create an injectable scaffold showing excellent biocompatibility and hemocompatibility. The hydrogel can be successfully delivered and localized to the suture sites of the USLS procedure, where it gradually degrades over six weeks. In situ mechanical testing 24 weeks post-operative in the multiparous USLS rat model shows the ultimate load (load at failure) to be 1.70 ± 0.36 N for the intact uterosacral ligament (USL), 0.89 ± 0.28 N for the USLS repair, and 1.37 ± 0.31 N for the USLS + hydrogel (USLS+H) repair (n = 8). These results indicate that the hydrogel composite significantly improves load required for tissue failure compared to the standard USLS, even after the hydrogel degrades, and that this hydrogel-based approach can potentially reduce the high failure rate associated with USLS procedures.

"It's messing with my physical health. It's messing with my sex life": Women's perspectives about, and impact of, pelvic health issues whilst awaiting specialist care. Int Urogynecol J 2022; 33:2463-2470. [PMID: 35362768 PMCID: PMC8972720 DOI: 10.1007/s00192-022-05176-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Accepted: 02/07/2022] [Indexed: 11/16/2022]
Abstract
Introduction and hypothesis Pelvic health conditions are a common health complaint among women worldwide, and conservative management is recognised as first-line treatment. There is often a time lag between referral from general practitioners to specialist consultation and conservative therapy. Therefore, the aim of this research was to explore perspectives from women with pelvic health conditions while they wait for specialist input, specifically about their understanding of their condition and its impact. Methods This research was underpinned by a qualitative descriptive methodology. Individual semi-structured interviews were conducted with women with pelvic health conditions who were waiting for specialist gynaecology consultation. Results A total of 11 women shared their perspectives about, and their understanding of, their condition and its impact. Thematic analysis of the interview data identified a variety of experiences and perspectives of women waiting to see the gynaecologist. These perspectives were categorised into four different themes: drivers to seek help, understanding the condition, experience/feeling being on the waiting list and expectations from the gynaecology team. Conclusion This study identified the main drivers for seeking help were worsening and/or persistent symptoms. Participants were able to articulate their symptoms, identify possible causes and describe various treatment options, and amenable to alternate treatment options. This research sheds light on the devastating impact of pelvic health conditions on women, which may be amplified while waiting to seek specialist input. There appears to be a need for health services to better support these women during this time of waiting.

Abstract
Introduction and hypothesis The objective was to explore the impact of levator ani muscle (LAM) trauma and pelvic floor contraction on symptoms and anatomy after pelvic organ prolapse (POP) surgery. Methods Prospective study including 200 women with symptomatic POP ≥ grade 2 examined 3 months prior to and 6 months after surgery. Prolapse in each compartment was graded using the Pelvic Organ Prolapse Quantification (POP-Q) system, and women answered yes/no to a question about bulge sensation. Pelvic floor muscle contraction was assessed with transperineal ultrasound measuring proportional change in levator hiatal anteroposterior diameter from rest to contraction. LAM trauma was diagnosed using tomographic ultrasound imaging. Statistical analysis was performed using multivariate logistic regression analysis. Results A total of 183 women (92%) completed the study. Anatomical recurrence (POP ≥ grade 2) was found in 76 women (42%), and a bulge sensation was reported by 35 (19%). Ninety-two women (50%) had LAM trauma, and this was associated with increased risk of anatomical recurrence (OR 2.1 (95% CI 1.1–4.1), p = 0.022), but not bulge sensation (OR 1.1 (95% CI 0.5–2.4), p = 0.809). We found a reduced risk of bulge sensation for women with absent to weak contraction compared with normal to strong contraction (OR 0.4 (95% CI 0.1–0.9), p = 0.031), but no difference in risk for POP ≥ 2 after surgery (OR 1.5 (95% CI 0.8–2.9), p = 0.223). Conclusions Levator ani muscle trauma was associated with increased risk of anatomical failure 6 months after POP surgery. Absent to weak pelvic floor muscle contraction was associated with reduced risk of bulge sensation after surgery.

Abstract
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.

Abstract
Pelvic floor disorders (PFDs), including fecal and urinary incontinence as well as pelvic organ prolapse, are common medical issues faced by one-third of all women across the lifespan. Despite this prevalence, many women are unaware of them, have highly stigmatized perceptions of them, and thus do not actively seek support or treatment for them. Given that PFDs can drastically impact quality of life to the point of social isolation and depression, this study examines chaos and desire as both lived and storied constructs that ultimately influence whether and how women with PFDs assert control over their social and corporeal disruption. Guided by narrative sensibilities and informed by semi-structured interviews with 22 women living with varying PFDs, our analysis highlights how chaos serves as a catalyst for continued chaos (i.e. barriers to seeking medical care), mitigation (i.e. resignation and/or public bodily containment), and/or change (i.e. motivations to seek medical care). These findings offer both theoretical and practical implications for helping individuals grappling with the dis-ease of PFDs (i.e. patients, providers, and practitioners) to envision and act otherwise.

Abstract
INTRODUCTION AND HYPOTHESIS This narrative review describes the existing epidemiologic literature and identifies gaps regarding pelvic organ prolapse (POP) prevalence, incidence, natural history, and current and future service needs. MATERIALS AND METHODS A PubMed search identified relevant citations published in 2000 or later. Pre-specified criteria were used to screen titles, abstracts, and manuscripts, including reference sections. Study findings were summarized to define what is known, identify gaps in current knowledge, and suggest priority areas for future research. RESULTS The reported prevalence of POP varies widely (1-65%) based on whether its presence is ascertained by symptoms (1-31%), pelvic examination (10-50%), or both (20-65%). Most existing population-based surveys do not include physical examination data. White women from higher income countries are overrepresented in the existing literature. Incidence and natural history data are limited and consist mainly of cohorts that follow women after pregnancy or menopause. Given global increases in aging populations in well-resourced countries, the need for POP treatment is anticipated to increase in the coming decades. In lower and middle income countries (LMICs) where demographic trends are different, there is a dearth of information about anticipated POP service needs. CONCLUSION Future POP incidence, prevalence, and natural history studies should include non-white women from LMICs and should combine pelvic examination data with validated patient-reported outcome measures when feasible. Anticipated future service needs differ globally, with a greater demand for POP treatment services in well-resourced settings where aging populations are prevalent.

Abstract
Hospital and community based-studies had been conducted for Urinary Incontinence (UI) in Sub-Sahara Africa (SSA) countries. A significant limitation of these studies is likely under-estimation of the burden of UI in SSA. It is therefore, imperative that a well-structured systematic review and meta-analytical models in SSA are required to accurately and reliably estimate the burden of UI. Medline/PubMed, Google Scholar, Africa Journal Online (AJOL) were searched to identified data on burden of UI studies in SSA. Two independent authors performed the initial screening of studies based on the details found in their titles and abstracts. The quality of the retrieved studies was assessed using the Newcastle-Ottawa Quality Assessment instrument. The pooled burden of UI was calculated using a weighted inverse variance random-effects model. A sub-group and meta-regression analyses were performed. Publication bias was checked by the funnel plot and Egger's test. Of the 25 studies included, 14 were hospital-based, 10 community- based, and 1 university-based studies involving an overall 17863 participants from SSA. The systematic review showed that the prevalence of UI ranged from 0.6% in Sierra Leone to 42.1% in Tanzania. The estimated pooled burden of UI across all studies was 21% [95% CI: 16%-26%, I2 = 91.01%]. The estimated pooled prevalence of stress UI was 52% [95% CI: 42%-62%], urgency UI 21% [95% CI: 15%-26%], and mixed UI 27% [95% CI: 20%-35%]. The common significant independent factors were; parity, constipation, overweight/obese, vaginal delivery, chronic cough, gestational age, and aging. One out of every five women in SSA suffers from UI. Parity, constipation, overweight/obesity, vaginal delivery, chronic cough, gestational age, and age were the most important risk variables. As a result, interventions aimed at reducing the burden of UI in SSA women aged 15 to 100 years old in the context of identified determinants could have significant public health implications.

Abstract
BACKGROUND The human foetus typically needs to rotate when passing through the tight birth canal because of the complex shape of the pelvis. In most women, the upper part, or inlet, of the birth canal has a round or mediolaterally oval shape, which is considered ideal for parturition, but it is unknown why the lower part of the birth canal has a pronounced anteroposteriorly oval shape. RESULTS Here, we show that the shape of the lower birth canal affects the ability of the pelvic floor to resist the pressure exerted by the abdominal organs and the foetus. Based on a series of finite element analyses, we found that the highest deformation, stress, and strain occur in pelvic floors with a circular or mediolaterally oval shape, whereas an anteroposterior elongation increases pelvic floor stability. CONCLUSIONS This suggests that the anteroposterior oval outlet shape is an evolutionary adaptation for pelvic floor support. For the pelvic inlet, by contrast, it has long been assumed that the mediolateral dimension is constrained by the efficiency of upright locomotion. But we argue that the mediolateral elongation has evolved because of the limits on the anteroposterior diameter imposed by upright posture. We show that an anteroposteriorly deeper inlet would require greater pelvic tilt and lumbar lordosis, which compromises spine health and the stability of upright posture. These different requirements of the pelvic inlet and outlet likely have led to the complex shape of the pelvic canal and to the evolution of rotational birth characteristic of humans.

Abstract
The term 'obstetrical dilemma' was coined by Washburn in 1960 to describe the trade-off between selection for a larger birth canal, permitting successful passage of a big-brained human neonate, and the smaller pelvic dimensions required for bipedal locomotion. His suggested solution to these antagonistic pressures was to give birth prematurely, explaining the unusual degree of neurological and physical immaturity, or secondary altriciality, observed in human infants. This proposed trade-off has traditionally been offered as the predominant evolutionary explanation for why human childbirth is so challenging, and inherently risky, compared to that of other primates. This perceived difficulty is likely due to the tight fit of fetal to maternal pelvic dimensions along with the convoluted shape of the birth canal and a comparatively low degree of ligamentous flexibility. Although the ideas combined under the obstetrical dilemma hypothesis originated almost a century ago, they have received renewed attention and empirical scrutiny in the last decade, with some researchers advocating complete rejection of the hypothesis and its assumptions. However, the hypothesis is complex because it presently captures several, mutually non-exclusive ideas: (i) there is an evolutionary trade-off resulting from opposing selection pressures on the pelvis; (ii) selection favouring a narrow pelvis specifically derives from bipedalism; (iii) human neonates are secondarily altricial because they are born relatively immature to ensure that they fit through the maternal bony pelvis; (iv) as a corollary to the asymmetric selection pressure for a spacious birth canal in females, humans evolved pronounced sexual dimorphism of pelvic shape. Recently, the hypothesis has been challenged on both empirical and theoretical grounds. Here, we appraise the original ideas captured under the 'obstetrical dilemma' and their subsequent evolution. We also evaluate complementary and alternative explanations for a tight fetopelvic fit and obstructed labour, including ecological factors related to nutrition and thermoregulation, constraints imposed by the stability of the pelvic floor or by maternal and fetal metabolism, the energetics of bipedalism, and variability in pelvic shape. This reveals that human childbirth is affected by a complex combination of evolutionary, ecological, and biocultural factors, which variably constrain maternal pelvic form and fetal growth. Our review demonstrates that it is unwarranted to reject the obstetrical dilemma hypothesis entirely because several of its fundamental assumptions have not been successfully discounted despite claims to the contrary. As such, the obstetrical dilemma remains a tenable hypothesis that can be used productively to guide evolutionary research.

Biomechanical trade-offs in the pelvic floor constrain the evolution of the human birth canal. Proc Natl Acad Sci U S A 2021; 118:2022159118.

Abstract
Compared with most other primates, humans are characterized by a tight fit between the maternal birth canal and the fetal head, leading to a relatively high risk of neonatal and maternal mortality and morbidities. Obstetric selection is thought to favor a spacious birth canal, whereas the source for opposing selection is frequently assumed to relate to bipedal locomotion. Another, yet underinvestigated, hypothesis is that a more expansive birth canal suspends the soft tissue of the pelvic floor across a larger area, which is disadvantageous for continence and support of the weight of the inner organs and fetus. To test this "pelvic floor hypothesis," we generated a finite element model of the human female pelvic floor and varied its radial size and thickness while keeping all else constant. This allowed us to study the effect of pelvic geometry on pelvic floor deflection (i.e., the amount of bending from the original position) and tissue stresses and stretches. Deflection grew disproportionately fast with increasing radial size, and stresses and stretches also increased. By contrast, an increase in thickness increased pelvic floor stiffness (i.e., the resistance to deformation), which reduced deflection but was unable to fully compensate for the effect of increasing radial size. Moreover, larger thicknesses increase the intra-abdominal pressure necessary for childbirth. Our results support the pelvic floor hypothesis and evince functional trade-offs affecting not only the size of the birth canal but also the thickness and stiffness of the pelvic floor.

Pelvic Floor Morbidity Following Vaginal Delivery versus Cesarean Delivery: Systematic Review and Meta-Analysis. J Clin Med 2021; 10:jcm10081652. [PMID: 33924472 PMCID: PMC8070303 DOI: 10.3390/jcm10081652] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 04/05/2021] [Accepted: 04/07/2021] [Indexed: 11/20/2022] Open
Abstract
Objective: To compare pelvic floor disorders between vaginal delivery (VD) and cesarean delivery (CD). Methods: For this study, a PUBMED database search was used, utilizing a combination of relevant medical subjects’ headings (MeSH) terms, with the following keywords: “Pelvic floor disorders” or “Pelvic floor morbidity” and “Delivery”. Search limits were articles in English or Spanish, about women, published from December 2009 to December 2019. The STATA 16 package was used for meta-analysis and data heterogeneity assessment. Results: Thirteen studies meeting eligibility criteria were identified comprising 1,597,303 participants. Abstract: Pelvic floor morbidity prevalence was Urinary Incontinence (UI) 27.9% (5411 patients in 7 studies with reported cases), Pelvic Organ Prolapse (POP) 14.2% (6019 patients in 8 studies with reported cases), and Anal Incontinence (AI) 0.4% (1,589,740 patients in 5 studies with reported cases). Our meta-analyses revealed significantly higher rates of all three morbidities and overall morbidity in the VD versus CD group: UI OR = 2.17, 95% CI 1.64–2.87, p for heterogeneity ≤ 0.0001, I2 = 84%; POP OR = 3.28, 95% CI 1.91–5.63, p for heterogenicity ≤ 0.043, I2 = 63%; AI OR = 1.53, 95% CI 1.32–1.77; p for heterogeneity ≤ 0.291, I2 = 20%; and overall morbidity (OR = 2.17, 95% CI 1.64–2.87; p for heterogeneity ≤ 0.0001, I2 = 84%). Conclusion: Vaginal delivery is directly related to the appearance of pelvic floor disorders, mainly UI, POP, and AI. The risk of POP should be taken into higher consideration after vaginal delivery and postpartum follow-up should be performed, to identify and/or treat it at the earliest stages.

Abstract
Abstract
Objective Pelvic floor dysfunction (PFD) is a major health care problem predominately affecting the elderly female. It impairs quality of life and patients increasingly expect a solution. Barium defaecating proctography (BDP) is frequently used in the assessment of patients with PFD. The aim of this study was to present our findings from BDP and to look at the proportion of patients who went on to have surgery following their investigations.
Methods All patients who underwent BDP in a tertiary referral center were identified retrospectively from the computerized radiology information system. Demographic data and radiologic findings were extracted. Data regarding those who had surgery were retrieved from the anonymized patient registry.
Results A total of 671 patients had a BDP during the study period. The main symptoms investigated were obstructed defecation or chronic constipation (64%). Complete barium evacuation was observed in 70% of the patients, while 17% were noted to have incomplete and 13% no evacuation. A large rectocele (>5 cm) was noted in 38% while nearly 5% had frank prolapse. There was no significant association between a rectocele and any of the presenting symptoms. Seventy-eight (12%) patients went on to have operation, of which 17 (22%) had multiple procedures. Three patients ended up with a permanent stoma.
Conclusion BDP contributes to decision making in patients with PFD. However, results need to be interpreted with caution and in conjunction with other tests and clinical examination to maintain a low rate of operation and reduce the risk of adverse outcomes for these patients.

Abstract
INTRODUCTION AND HYPOTHESIS The aim of this study was to develop a Polish language version of the short form of the Pelvic Floor Impact Questionnaire 7 (PFIQ-7) and to validate it in a sample of Polish-speaking women with pelvic floor disorders (PFDs). METHODS The PFIQ-7 was initially translated in a stepwise fashion as guided by the International Urogynecological Association (IUGA) Translation Protocol. First, two bilingual physicians in Poland and the USA performed a forward translation of the PFIQ-7. Next, a community review process was undertaken consisting of one-on-one cognitive interviews with 20 patients. The translated questionnaire was then back translated into English. The final Polish version of the PFIQ-7 was subsequently administered to Polish-speaking patients presenting with PFDs at university-based urogynecology clinics in Poland and the USA along with a Polish version of the Pelvic Floor Distress Inventory (PFDI-20). Internal consistency and criterion validity were assessed. RESULTS A total of 225 women with PFDs enrolled in this multicenter study. Complete data from 185 women in Poland and 40 primarily Polish-speaking women in the USA were analyzed. Participants had a mean age of 60.1 ± 11.1 years and mean body mass index (BMI) 27.9 ± 4.9. The Poland and United States cohorts did not vary significantly in age, BMI, or education level. PFIQ-7 internal consistency as measured by Cronbach's alpha was good (0.93). Criterion validity was adequate between responses on the PFIQ-7 and PFDI-20 prolapse, colorectal, and urinary subscales (0.62-0.69, p < 0.05). CONCLUSIONS The Polish version of the PFIQ-7 is a reliable tool for evaluating pelvic floor symptoms in Polish-speaking women with PFDs.

Abstract
This study was carried out to observe the impact of insulin-like growth factor-1 (IGF-1) on human vaginal fibroblasts (HVFs) in the context of pelvic organ prolapse (POP) and to explore its effects on mitogen-activated protein kinases (MAPK) and nuclear factor-κB (NF-κB) signaling pathways. First, it was found that IGF-1 expression reduced in the vaginal wall tissues derived from POP compared to that in non-POP cases. Then the role of IGF-1 was explored in HVFs and thiazolyl blue tetrazolium bromide (MTT) and flow cytometry were used to detect cell viability and cell apoptosis. Western blot assay and quantitative real-time polymerase chain reaction were used to detect the protein and mRNA expression. The results showed that knockdown of IGF-1 inhibited the cell viability of HVFs, promoted the cell apoptosis of HVFs, and decreased the expression of types I and III collagen in HVFs, which was through inhibiting the expression of IGF-1 receptor and MAPK/NF-κB pathways. However, IGF-1 plasmid had the opposite effects on HVFs. In conclusion, our results showed that IGF-1 could activate MAPK and NF-κB pathways, thereby enhancing collagen metabolism and the growth of vaginal wall fibroblasts then to inhibit POP development.

Abstract
OBJECTIVES To evaluate the effect of preoperative pelvic floor muscle training (PFMT) on pelvic floor muscle (PFM) contraction, symptoms of pelvic organ prolapse (POP) and anatomical POP, 6 months after prolapse surgery, and to assess the overall changes in PFM contraction, POP symptoms and pelvic organ descent after surgery. METHODS This was a randomized controlled trial of 159 women with symptomatic POP, Stage 2 or higher, scheduled for surgery. Participants were randomized to intervention including daily PFMT from inclusion to surgery (n = 81) or no intervention (controls; n = 78). Participants were examined at inclusion, on the day of surgery and 6 months after surgery. PFM contraction was assessed by: vaginal palpation using the Modified Oxford scale (MOS; 0-5); transperineal ultrasound, measuring the percentage change in levator hiatal anteroposterior diameter (APD) from rest to maximum PFM contraction; vaginal manometry; and surface electromyography (EMG). POP distance from the hymen in the compartment with the most dominant prolapse and organ descent in the anterior, central and posterior compartments were measured on maximum Valsalva maneuver. POP symptoms were assessed based on the sensation of vaginal bulge, which was graded using a visual analog scale (VAS; 0-100 mm). Linear mixed models were used to assess the effect of PFMT on outcome variables. RESULTS Of the 159 women randomized, 151 completed the study, comprising 75 in the intervention and 76 in the control group. Mean waiting time for surgery was 22 ± 9.7 weeks and follow-up was performed on average 28 ± 7.8 weeks after surgery. Postoperatively, no difference was found between the intervention and control groups with respect to PFM contraction assessed by vaginal palpation (MOS, 2.4 vs 2.2; P = 0.101), manometry (19.4 vs 19.7 cmH2 O; P = 0.793), surface EMG (33.5 vs 33.1 mV; P = 0.815) and ultrasound (change in hiatal APD, 20.9% vs 19.3%; P = 0.211). Furthermore, no difference between groups was found for sensation of vaginal bulge (VAS, 7.4 vs 6.0 mm; P = 0.598), POP distance from the hymen in the dominant prolapse compartment (-1.8 vs -2.0 cm; P = 0.556) and sonographic descent of the bladder (0.5 vs 0.8 cm; P = 0.058), cervix (-1.3 vs -1.1 cm; P = 0.569) and rectal ampulla (0.3 vs 0.4 cm; P = 0.434). In all patients, compared with findings at initial examination, muscle contraction improved after surgery, as assessed by palpation (MOS, 2.1 vs 2.3; P = 0.007) and ultrasound (change in hiatal APD, 17.5% vs 20.1%; P = 0.001), and sensation of vaginal bulge was reduced (VAS, 57.6 vs 6.7 mm; P < 0.001). In addition, compared with the baseline examination, POP distance from the hymen in the dominant prolapse compartment (1.9 vs -1.9 cm; P < 0.001) and sonographic descent of the bladder (1.3 vs 0.6 cm; P < 0.001), cervix (0.0 vs -1.2 cm; P < 0.001) and rectal ampulla (0.9 vs 0.4 cm; P = 0.001) were reduced. CONCLUSIONS We found no effect of preoperative PFMT on PFM contraction, POP symptoms or anatomical prolapse after surgery. In all patients, PFM contraction and POP symptoms were improved at the 6-month follow-up, most likely due to the anatomical correction of POP. Copyright © 2020 ISUOG.

Abstract
INTRODUCTION Anterior colporrhaphy (AC) is one of the most commonly performed surgical procedures for pelvic organ prolapse treatment; however, there are only few data in the literature regarding its long-term outcomes. Our aim was to assess the long-term efficacy and satisfaction rate after AC. METHODS Patients who underwent AC at our institution from 2011 to 2014 were invited to this follow-up study, which took place in January-February 2019. Medical history and gynaecological examination with POP-Q assessment were performed. Patients filled out validated questionnaires UIQ-7, CRAIQ-7, POPIQ-7, PFIQ-7, POPDI-6, CRADI-8, and UDI-6 and evaluated their satisfaction with the procedure. Objective success was defined as anterior wall prolapse stage 0 or 1 assessed by the POP-Q system. Subjective success was defined as the absence of bulging sensation or a sense of falling out that can be felt or seen in the vaginal area. Data were analysed using descriptive statistics and non-parametric tests. RESULTS Seventy out of 137 (51.1%) patients attended the follow-up. Mean follow-up period up was 74.1 ± 12.6 months. Two patients were excluded from the analysis because they had another surgical procedure due to central compartment prolapse. Of the remaining patients, 50 had AC and 18 had AC and posterior colporrhaphy (PC). Objective success rate was 13.2% and subjective success rate was 68.7%. Almost all patients (98.5%) were satisfied with the procedure. In the group of patients with objective recurrence, 66.1% had no prolapse symptoms. CONCLUSION Despite having a low objective success rate, patients' satisfaction with AC is very high.

Abstract
OBJECTIVE To show the feasibility of tendon transplantation for minimally invasive pectopexy in pelvic organ prolapse repair. STUDY DESIGN Patients with uterine or vaginal vault prolapse (POP-Q point C Stage 2-4) were offered laparoscopic pectopexy by means of autologous semitendinosus tendon transplantation. This paper presents a case series and describes the technique regarding the first 10 patients who underwent surgery. After preparing the vagina or cervix for laparoscopic pectopexy a tendon of the patient's semitendinosus muscle was stripped and brought intraabdominally through the 10 mm trocar. The tendon was fixed between the cervix or vagina and to the pectineal ligaments on both sides of the pelvis. RESULTS All operations were performed successfully without complications. Vaginal examination demonstrated the intended elevation of the middle compartment. Mobility and power of the affected leg did not change. Recovery was fast, and discharge was possible between the second and third postoperative day. CONCLUSION Our approach demonstrates the feasibility and safety of a laparoscopic pectopexy with a semitendinosus autograft instead of a synthetic mesh. The experience from orthopedic surgery shows that a semitendinosus tendon autograft is long-lasting and stable. In addition, the morbidity on the operated leg is low.

Abstract
AIMS In the current climate of evidence-based health care, the aim of this meta-synthesis was to collect and systematically analyse data from primary qualitative studies on pelvic organ prolapse (POP), to identify patient-centered perspectives on the natural course of POP. Information acquired in this study may be useful for ongoing research towards the development of core outcome sets (COS) in pelvic floor disorders. METHODS A CHORUS Working Group performed a standardized search of three different databases (Medline, Embase, Scopus), from inception to October 2019. We selected qualitative studies on women's perspectives on POP that were published in the English language. Three reviewers independently evaluated the quality of eligible papers and highlighted recurrent themes based on patient perspectives. RESULTS Eighteen qualitative studies including a total of 497 patients were assessed in this analysis. Our study revealed five superordinate themes, recurrently encountered in qualitative studies on POP: awareness of POP (6 studies), communication (9 studies), treatments (10 studies), effects on quality of life (6 studies), and self-image (3 studies). Five out of 10 quality criteria were met by all the studies included, based on an assessment performed using the critical appraisal skills program. CONCLUSIONS This is the first synthesis of qualitative studies that address POP-related experiences of women, highlighting five superordinate themes, of which treatment was the most commonly reported one. This synthesis' findings may guide quantitative research priorities and will hopefully contribute to the development of a COS for POP.

Abstract
OBJECTIVE To assess the outcomes of surgical repair of anterior apical prolapse using the 6-strap mesh implant. STUDY DESIGN The prospective study included 100 patients with genitourinary prolapse. We used advanced 6-strap mesh implant. The results were assessed at 1 (n = 100) and 12 (n = 93) months after surgery. Maximum follow-up was over 4 years. The anatomical outcomes according to the Pelvic Organ Prolapse Quantification system and intraoperative and postoperative complications were assessed. Stage II and higher prolapse was considered to be a recurrence. The quality of life and sexual function were assessed using Pelvic Organ Prolapse Distress Inventory 20, Pelvic Floor Impact Questionnaire 7, and Pelvic Organ Prolapse/Incontinence Sexual Questionnaire 12. RESULTS Median age was 57 years (34-78 years (95% confidence interval)). All patients had stage III cystocele. The anterior vaginal wall descent in all the patients was associated with uterine descent: 37 (37%), stage II; 60 (60%), stage III; in 3 (3%), stage IV. In eight cases, postoperative de novo stress urinary incontinence developed. The quality of life improved in 93 (93%) women as judged by the Pelvic Floor Distress Inventory 20 data and in 87 (87%) women, according to the Pelvic Floor Impact Questionnaire 7 data. The desirable anatomical result (⩽stage I according to the Pelvic Organ Prolapse Quantification system) was achieved in 97 (97%) patients. With the exception of mesh fragment excision due to erosion (grade 3a), all the complications were classified as grade I according to the Clavien-Dindo classification. CONCLUSION Genitourinary prolapse repair using 6-strap mesh is efficacious and relatively safe. The method demonstrates good anatomical results in relation to both anterior and apical prolapses with relatively short-term complications.

Abstract
BACKGROUND Pelvic organ prolapse, various types of incontinence (urinary incontinence, defecatory dysfunction), chronic cystourethritis, and sexual dysfunctions remain between the most common disorders in urogynecology. Currently, it is believed that the nature and number of births plays a major role in their development. Moreover, after these events, pelvic floor tissues may not recover to their original statuses. The close anatomical relationship among the vaginal wall, bladder and rectum often contribute to the emergence of anatomical-functional failure of adjacent organs and systems. BASIC PROCEDURES The aim of this study was to investigate the effect of consecutive pregnancies on pelvic floor soft tissues, conducting biomechanical and histological analysis. Fifteen Swifter ewes: virgins, parous and pregnant were used. Samples, for uniaxial tension tests and histological analysis, were cut out from fresh tissue. A description of the mechanical properties of native tissue was obtained from the stress-strain curve. Histological samples were stained with Miller's Elastica staining and analyzed using ImageJ software. Collagen, elastin, and smooth muscle contents (%) were analyzed along the full wall thickness of the selected organs. The links between mechanical properties of the soft tissues and histological parameters were analyzed. MAIN FINDINGS Mechanically, vaginal wall tissue and cervix of pregnant sheep were more compliant. In contrast, bladder and rectum became stiffer and had the highest total collagen content. Parous sheep rectum and bladder were stiffer, compared to virgin sheep. PRINCIPAL CONCLUSIONS Tensile strength appears to be linked to total collagen content. Elastin and smooth muscle show a direct influence on tissue compliance.

Abstract
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.

Abstract
INTRODUCTION AND HYPOTHESIS The aim of this study was to develop a Polish language version of the short form of the Pelvic Floor Distress Inventory (PFDI-20) and to validate it in a sample of Polish-speaking women with pelvic floor disorders (PFDs). METHODS The PFDI-20 was initially translated in a stepwise fashion as guided by the International Urogynecological Association (IUGA) Translation Protocol. After initial forward translation from English to Polish, a community review process consisting of cognitive interviews and confirmation via back translation was performed. The final Polish version of the PFDI-20 was administered to Polish-speaking patients presenting with PFDs at university-based urogynecology clinics in Poland and the United States, along with a Polish version of the King's Health Questionnaire (KHQ). Internal consistency and criterion validity were assessed. Test-retest reliability was assessed in 100 patients after 2 weeks. RESULTS A total of 254 women with PFDs enrolled in this multicenter study. Complete data from 44 Polish-speaking women in the United States and 200 women in Poland were analyzed. Participants had a mean age of 60.3 ± 11.2 years and mean body mass index (BMI) 27.6 ± 4.7. Internal consistency as measured by Cronbach's alpha was good (0.89). Criterion validity was adequate between responses on the KHQ and PFDI-20 with Pearson correlations in particular domains (0.27-0.50, P < 0.05). Excellent test-retest reliability was demonstrated by intraclass correlation using a two-way mixed-effects model with absolute agreement (0.87). CONCLUSIONS The Polish version of the PFDI is a reliable tool for evaluating pelvic floor symptoms in Polish-speaking women with PFDs.

Abstract
AIMS To characterize the contractile properties of the bulbospongiosus (Bsm), isquiocavernosus (Ism), and pubococcygeus muscles (Pcm), and their involvement in the genesis of vaginal pressure in nulliparous and multiparous rabbits. METHODS Age-matched nulliparous and multiparous rabbits were used to record the isometric contractile responses of each muscle as well as the intravaginal pressure evoked by single square electrical pulses and stimulation trains of ascending frequency. To establish significant differences between groups, two-tail unpaired Student t tests were carried out. The linear correlation between intravaginal pressure and muscle contractile force was analyzed with Pearson correlation tests. For all cases, a P ≤ 0.05 was set as statistically significant. RESULTS Multiparity decreased the contractile force of Bsm and Ism generated by high-frequency stimulation trains. The normalized force of the Pcm increased when evoked at 1, 4, and 10 Hz while this decreased at higher frequencies (20, 50, and 100 Hz). The contraction of both Bsm and Ism raised particularly the pressure on the perineal vagina while that of the Pcm increased the pressure in the pelvic vagina. Such a functional segregation is still present in multiparous rabbits albeit it was modified. CONCLUSIONS Multiparity induces changes in the contractile responses of Bsm, Ism, and Pcm, which alterates the vaginal pressure.

Abstract
AIM The study aimed to determine the current state of UK pelvic floor services and to discuss future strategies. METHOD A questionnaire developed by the Pelvic Floor Society was sent in 2014 to the 175 colorectal units recognized by the Association of Coloproctology of Great Britain and Ireland. Questions included type of centre, frequency of pelvic floor clinics/interdisciplinary joint pelvic floor clinics/multidisciplinary meetings (MDMs) and workload. RESULTS Sixty-seven (38%) centres replied including 75% of units with a consultant who was as member of the Pelvic Floor Society. Of the 67 centres 39% were tertiary centres for pelvic floor surgery (tertiary), 48% performed some pelvic floor surgery (regional) and 13% did not perform any (local). Ninety-six per cent of tertiary referral centres served a population over 500 000. The mean number of whole time equivalent consultants in tertiary centres was 1.03 and 0.77 in regional centres. Eighty per cent of tertiary centres and 56% of regional centres ran pelvic floor clinics. Eighty-four per cent of tertiary referral and 75% of regional units held or attended an MDM. Anal ultrasonography, anorectal physiology and proctography were performed in 96% of tertiary centres compared with 50% of non-tertiary units. CONCLUSION The provision of pelvic floor services includes local, regional and tertiary centres. The overall response rate was low (38%) and biased to centres with a consultant who was a member of the Pelvic Floor Society. Not all regional or tertiary centres held an MDM or a pelvic floor clinic. Given the nature of pelvic floor pathology an integrated service should be aimed at linking different centres and specialities.

Abstract
OBJECTIVE The decline in available oestrogen after menopause is a possible etiological factor in pelvic floor disorders like vaginal atrophy (VA), urinary incontinence (UI), overactive bladder (OAB) and pelvic organ prolapse (POP). This systematic review will examine the evidence for local oestrogen therapy in the treatment of these pelvic floor disorders. EVIDENCE ACQUISITION We performed a systematic search in MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials and the non-MEDLINE subset of PubMed from inception to May 2014. We searched for local oestrogens and VA (I), UI/OAB (II) and POP (III). Part I was combined with broad methodological filters for randomized controlled trials (RCTs) and secondary evidence. For part I and II two reviewers independently selected RCTs evaluating the effect of topical oestrogens on symptoms and signs of VA and UI/OAB. In part III all studies of topical oestrogen therapy in the treatment of POP were selected. Data extraction and the assessment of risk of bias using the Cochrane Risk of Bias Tool was undertaken independently by two reviewers. EVIDENCE SYNTHESIS The included studies varied in ways of topical application, types of oestrogen, dosage and treatment durations. Objective and subjective outcomes were assessed by a variety of measures. Overall, subjective and urodynamic outcomes, vaginal maturation and vaginal pH changed in favor of vaginal oestrogens compared to placebo. No obvious differences between different application methods were revealed. Low doses already seemed to have a beneficial effect. Studies evaluating the effect of topical oestrogen in women with POP are scarce and mainly assessed symptoms and signs associated with VA instead of POP symptoms. CONCLUSION Topical oestrogen administration is effective for the treatment of VA and seems to decrease complaints of OAB and UI. The potential for local oestrogens in the prevention as well as treatment of POP needs further research.

Abstract
OBJECTIVE To describe the effects of childhood functional constipation compared with functional constipation plus fecal incontinence on quality of life, evaluating effects on physical, psychosocial, and family functioning. STUDY DESIGN This prospective, multicenter study collected data from 5 regional children's hospitals. Children meeting Rome III criteria for functional constipation were included. Parents completed the following 5 instruments: Pediatric Quality of Life Inventory (PedsQL), PedsQL-Family Impact Module, Functional Disability Inventory-Parent Version, Pediatric Inventory for Parents (PIP), and Pediatric Symptom Checklist-Parent Report. RESULTS Families of 410 children aged 2-18 years (mean [SD], 7.8 [3.5] years; 52% male) were included. Children with functional constipation+fecal incontinence had worse quality of life than children with functional constipation alone (PedsQL Total Score, P ≤ .03). Older children with functional constipation + fecal incontinence had lower quality of life than their younger counterparts (PedsQL Total Score, P ≤ .047). Children with functional constipation+fecal incontinence had worse family functioning (PedsQL-Family Impact Module Total Score, P ≤ .012), greater parental stress (PIP-F Total Score, P ≤ .016; PIP-D Total Score, P ≤ .013), and poorer psychosocial functioning (Pediatric Symptom Checklist Total Score, P ≤ .003). There were no statistically significant between-group differences in physical functioning based on the functional Disability Inventory. CONCLUSION Fecal incontinence significantly decreases quality of life compared with functional constipation alone in children. Older children with functional constipation+fecal incontinence may be at particular risk. Strategies for early identification and treatment of constipation along with diagnosis and treatment of related adjustment difficulties may mitigate the negative impact of this highly prevalent condition.

Abstract
BACKGROUND Pelvic floor dysfunction (PFD) is the most common complication of childbirth. Assumptions have been made that perineal trauma increases the risk of PFD compared to an intact perineum, however the evidence for this is lacking. The aim of this study was to explore the relationship between perineal outcome and postpartum PFD. MATERIALS AND METHODS Prospective cohort study design, with a self-reported quality of life (QOL) questionnaire mailed to all primiparous women with a non-instrumental delivery at The Townsville Hospital between 2011 and 2012 (n = 766). ANOVA was used to compare how the symptoms of PFD affect QOL in women with an intact perineum, episiotomy or spontaneous tear. RESULTS Seventy-nine percent of the population had perineal injury; 60% had a spontaneous tear and 19% had an episiotomy. Ninety-seven percent of women who completed the questionnaire (n = 196) complained of PFD symptoms. Women with episiotomy had the best QOL, reporting the lowest levels of urinary dysfunction (statistically significant). No differences between the groups were found for symptoms of bowel, prolapse or sexual dysfunction. CONCLUSIONS This study shows a relationship between perineal outcome and PFD and suggests that an episiotomy is associated with the least morbidity due to symptoms of urinary incontinence. Additional large-scale prospective research is required to further investigate and delineate the impact of childbirth on PFD.

Abstract
The focus of this study was to determine the structural and mechanical properties of two major ligaments that support the uterus, cervix, and vagina: the cardinal ligament (CL) and the uterosacral ligament (USL). The adult swine was selected as animal model. Histological analysis was performed on longitudinal and cross sections of CL and USL specimens using Masson׳s trichrome and Verhoeff-van Giesson staining methods. Scanning electron microscopy was employed to visualize the through-thickness organization of the collagen fibers. Quasi-static uniaxial tests were conducted on specimens that were harvested from the CL/USL complex of a single swine. Dense connective tissue with a high content of elastin and collagen fibers was observed in the USL. Loose connective tissue with a considerable amount of smooth muscle cells and ground substance was detected in both the CL and USL. Collagen fibers, smooth muscle cells, blood vessels, and nerve fibers were arranged primarily in the plane of the ligaments. The USL was significantly stronger than the CL with higher ultimate stress and tangent modulus of the linear region of the stress-strain curve. Knowledge about the mechanical properties of the CL and USL will aid in the design of novel mesh materials, stretching routines, and surgical procedures for pelvic floor disorders.

Abstract
BACKGROUND The aim of this study was to describe the results of a 1-year patient follow-up after anterior vaginal wall darn, a novel technique for the repair of anterior vaginal wall prolapse. METHODS Fifty-five patients with anterior vaginal wall prolapse underwent anterior vaginal wall darn. The anterior vaginal wall was detached using sharp and blunt dissection via an incision beginning 1 cm proximal to the external meatus and extending to the vaginal apex. The space between the tissues that attach the lateral vaginal walls to the arcus tendineus fasciae pelvis was then darned. Cough Stress Test, Pelvic Organ Prolapse Quantification, seven-item Incontinence Impact Questionnaire, and six-item Urogenital Distress Inventory scores were performed 1-year postoperatively to evaluate recovery. RESULTS One-year postoperatively, all patients were satisfied with the results of the procedure. No patient had vaginal mucosal erosion or any other complication. CONCLUSIONS One-year postoperative findings for patients in this series indicate that patients with stage II-III anterior vaginal wall prolapse were successfully treated with the anterior vaginal wall darn technique.

Abstract
OBJECTIVE To compare the impact of the prototype prolapse mesh Gynemesh PS with that of two new-generation lower stiffness meshes, UltraPro and SmartMesh, on vaginal morphology and structural composition. DESIGN A mechanistic study employing a nonhuman primate model. SETTING Magee-Womens Research Institute at the University of Pittsburgh. POPULATION Parous rhesus macaques, with similar age, weight, parity and Pelvic Organ Prolapse-Questionnaire scores. METHODS Following Institutional Animal Care Use Committee approval, 50 rhesus macaques were implanted with Gynemesh PS (n = 12), UltraPro with its blue line perpendicular to the longitudinal axis of vagina (n = 10), UltraPro with its blue line parallel to the longitudinal axis of vagina (n = 8) or SmartMesh (n = 8) via sacrocolpopexy following hysterectomy. Sham-operated animals (n = 12) served as controls. MAIN OUTCOME MEASURES The mesh-vagina complex was removed after 12 weeks and analysed for histomorphology, in situ cell apoptosis, total collagen, elastin, glycosaminoglycan content and total collagenase activity. Appropriate statistics and correlation analyses were performed accordingly. RESULTS Relative to sham and the two lower stiffness meshes, Gynemesh PS had the greatest negative impact on vaginal histomorphology and composition. Compared with sham, implantation with Gynemesh PS caused substantial thinning of the smooth muscle layer (1557 ± 499 μm versus 866 ± 210 μm, P = 0.02), increased apoptosis particularly in the area of the mesh fibres (P = 0.01), decreased collagen and elastin content (20%, P = 0.03 and 43%, P = 0.02, respectively) and increased total collagenase activity (135%, P = 0.01). Glycosaminoglycan, a marker of tissue injury, was highest with Gynemesh PS compared with sham and other meshes (P = 0.01). CONCLUSION Mesh implantation with the stiffer mesh Gynemesh PS induced a maladaptive remodelling response consistent with vaginal degeneration.

Abstract
Although common in women, mixed urinary incontinence (MUI) is under-reported and under-treated. It is linked to concomitant disturbances, which may be due to childbirth, ageing, or other medical conditions, in the complex bladder-urethra coordinated system of urine storage and emptying. Primary care physicians can evaluate MUI through history and simple clinical assessment or they can avail of more complex device and tools, such as urodynamic assessment. There is a wide range of therapeutic options. The recent proliferation of new drug treatments and surgical devices for urinary incontinence offers innovative strategies for therapy but products risk being introduced without long-term safety and efficacy assessment. Direct-to-consumer advertising has increased public awareness of MUI.

Abstract
AIM Accurate and reliable imaging of pelvic floor dynamics is important for tailoring treatment in pelvic floor disorders; however, two imaging modalities are available. Barium proctography (BaP) is widely used, but involves a significant radiation dose. Magnetic resonance (MR) proctography allows visualization of all pelvic midline structures but patients are supine. This project investigates whether there are measurable differences between BaP and MR proctography. Patient preference for the tests was also investigated. METHODS Consecutive patients referred for BaP were invited to participate (National Research Ethics Service approved). Participants underwent BaP in Poole and MR proctography in Dorchester. Proctograms were reported by a consultant radiologist with pelvic floor subspecialization. RESULTS A total of 71 patients were recruited. Both tests were carried out on 42 patients. Complete rectal emptying was observed in 29% (12/42) on BaP and in 2% (1/42) on MR proctography. Anismus was reported in 29% (12/42) on BaP and 43% (18/42) on MR proctography. MR proctography missed 31% (11/35) of rectal intussusception detected on BaP. In 10 of these cases no rectal evacuation was achieved during MR proctography. The measure of agreement between grade of rectal intussusception was fair (κ=0.260) although MR proctography tended to underestimate the grade. Rectoceles were extremely common but clinically relevant differences in size were evident. Patients reported that they found MR proctography less embarrassing but harder to empty their bowel. CONCLUSIONS The results demonstrate that MR proctography under-reports pelvic floor abnormalities especially where there has been poor rectal evacuation.

Abstract
OBJECTIVE Stereological evaluation of the concentration of type I and III collagen fibers in the urethral tissue of rats subjected to simulated labor and oophorectomy. To compare the concentrations of collagen between oophorectomized and non-oophorectomized rats. MATERIAL AND METHOD Sixty adult Wistar rats were divided into six groups. A group made up of virgin rats was used as control group and another group was made up of oophorectomized rats. Two groups underwent vaginal distention for 30 and 120 minutes, respectively. The two other groups were subjected to the same distension periods, followed by oophorectomy. Sixty days later, euthanasia and removal of urethral tissue was carried out for stereological analysis of type I and III collagen after staining with hematoxylin and eosin and picrosirius red. RESULTS A decrease in estrogen levels was observed in the oophorectomized rats. There was a reduction of type III collagen in the oophorectomized control group compared to the control group when analyzed independently. No significant differences were observed among the other groups. Type I collagen decreased in all groups compared to the control group. However, in the prolonged vaginal distension and oophorectomy group, these fibers increased. CONCLUSION In normal rats, simulation of labor does not alter the collagen III levels. In hypoestrogenic rats, the concentration of collagen type I and III decreased, except in those undergoing prolonged labor simulation in which collagen I increased.

Abstract
BACKGROUND The use of standardized mesh kits for repair of pelvic-organ prolapse has spread rapidly in recent years, but it is unclear whether this approach results in better outcomes than traditional colporrhaphy. METHODS In this multicenter, parallel-group, randomized, controlled trial, we compared the use of a trocar-guided, transvaginal polypropylene-mesh repair kit with traditional colporrhaphy in women with prolapse of the anterior vaginal wall (cystocele). The primary outcome was a composite of the objective anatomical designation of stage 0 (no prolapse) or 1 (position of the anterior vaginal wall more than 1 cm above the hymen), according to the Pelvic Organ Prolapse Quantification system, and the subjective absence of symptoms of vaginal bulging 12 months after the surgery. RESULTS Of 389 women who were randomly assigned to a study treatment, 200 underwent prolapse repair with the transvaginal mesh kit and 189 underwent traditional colporrhaphy. At 1 year, the primary outcome was significantly more common in the women treated with transvaginal mesh repair (60.8%) than in those who underwent colporrhaphy (34.5%) (absolute difference, 26.3 percentage points; 95% confidence interval, 15.6 to 37.0). The surgery lasted longer and the rates of intraoperative hemorrhage were higher in the mesh-repair group than in the colporrhaphy group (P<0.001 for both comparisons). Rates of bladder perforation were 3.5% in the mesh-repair group and 0.5% in the colporrhaphy group (P=0.07), and the respective rates of new stress urinary incontinence after surgery were 12.3% and 6.3% (P=0.05). Surgical reintervention to correct mesh exposure during follow-up occurred in 3.2% of 186 patients in the mesh-repair group. CONCLUSIONS As compared with anterior colporrhaphy, use of a standardized, trocar-guided mesh kit for cystocele repair resulted in higher short-term rates of successful treatment but also in higher rates of surgical complications and postoperative adverse events.

Abstract
OBJECTIVES To assess the effect of coffee and tea consumption on symptoms of urinary incontinence. DESIGN Population-based study. SETTING The Swedish Twin Register. POPULATION In 2005, all twins born between 1959 and 1985 in Sweden (n = 42,852) were invited to participate in a web-based survey to screen for common complex diseases and common exposures. The present study was limited to female twins with information about at least one urinary symptoms and coffee and tea consumption (n = 14,031). MAIN OUTCOME MEASURE The association between coffee and tea consumption and urinary incontinence, as well as nocturia, was estimated as odds ratios (ORs) with 95% confidence intervals. RESULTS Women with a high coffee intake were at lower risk of any urinary incontinence (OR 0.78, 95% CI 0.64-0.98) compared with women not drinking coffee. Coffee intake and incontinence subtypes showed no significant associations whereas high tea consumption was specifically associated with a risk for overactive bladder (OR 1.34, 95% CI 11.07-1.67) and nocturia (OR 1.18, 95% CI 1.01-1.38). Results from co-twin control analysis suggested that the associations observed in logistic regression were mainly the result of familial effects. CONCLUSIONS This study suggests that coffee and tea consumption has a limited effect on urinary incontinence symptoms. Familial and genetic effects may have confounded the associations observed in previous studies.

Abstract
INTRODUCTION AND HYPOTHESIS Information on the prevalence, risk factors and social consequences of pelvic floor dysfunction (PFD) affecting women in 16 low-income and lower middle-income countries is reviewed. METHODS Medline searches were performed for articles dealing with prevalence of PFD. RESULTS Thirty studies were identified. The mean prevalence for pelvic organ prolapse was 19.7% (range 3.4-56.4%), urinary incontinence (UI) was 28.7% (range 5.2-70.8%) and faecal incontinence (FI) was 6.9% (range 5.3-41.0%). Risk factors for PFD are similar to those in more affluent countries particularly increased age and parity, but additionally, PFD is associated with other factors including poor nutrition and heavy work. The social consequences of PFD conditions can be devastating. CONCLUSIONS Pelvic organ prolapse and urinary and faecal incontinence are significant problems in developing countries. Access to health care to manage these conditions is often limited, and women usually have to live with the consequences for the rest of their lives.

Abstract
INTRODUCTION AND HYPOTHESIS Many physicians in primary care and medical/surgical specialties will care for female patients with pelvic floor disorders (PFD). METHODS A survey was mailed to 266 United States and Canadian clerkship directors that queried how medical students were being educated in PFD. RESULTS Forty-four percent of clerkship directors responded. The mean clerkship size was 105 medical students. Over 97% of third year medical students received lectures on hypertension in pregnancy, normal labor, and abnormal uterine bleeding and at least 90% received lectures on obstetric hemorrhage, placenta previa, and menstruation. Forty percent to 85% of medical students received lectures in PFD depending on the topic. Eighty percent of medical students had no exposure to PFD during their first 2 years of medical school. During their third year, 95% of the students were exposed to PFD topics but only 60% had an opportunity to spend at least a day in an urogynecology practice. Clerkship directors indicate that PFD are relevant to medical student training, however, they have limited time in the clerkship to cover all of the required topics. CONCLUSIONS We are missing an important opportunity to educate future clinicians about PFD, which dramatically impact women's quality of life.
