Evaluation of free mobile health applications for pelvic organ prolapse and urinary incontinence.

BACKGROUND: Technology is becoming increasingly integrated into healthcare, including the rapid development of mobile health (mHealth) applications (apps) for various medical conditions such as urinary incontinence and pelvic organ prolapse (POP). As patients turn to these sources more frequently, closer evaluation of the apps becomes more important. OBJECTIVES: To (1) evaluate free applications designed for POP and urinary incontinence using the Xcertia guidelines for medical app quality, (2) analyze user sentiment of the apps, and (3) evaluate app information for quality, understandability, and actionability with the DISCERN and the Patient Education Materials Assessment Tool (PEMAT) tools. METHODS: Mobile medical apps were identified on the Apple App Store or Google Play Store with keywords "pelvic organ prolapse," "incontinence," or "bladder." Exclusion criteria included 1) not free, 2) not updated in past year, 3) required a product for use, 4) not in English. Apps were evaluated using the Xcertia Guidelines. Categories included Operability, Privacy, Security, Content, and Usability. Ratings and sentiment of reviews were assessed, and associations analyzed with one-sided Fisher's exact test. Apps with an informational component were evaluated for quality, usability and actionability using DISCERN and PEMAT criteria. RESULTS: Overall, a total of 73 apps were found and 28 were included. There was an average number of ratings of 2341 and an average score of 3.39 for all the apps included. The average number of reviews was 216.2, with the majority of reviews having positive sentiment. A high number of ratings was associated with a high rating score (p < 0.05) and a high number of reviews was associated with a high percentage of positive reviews (p < 0.05). Based on Xcertia Guidelines, all apps met the guidelines for privacy, security, and usability. Regarding content, 67.9 % of apps incorporated an informational component, but only 17.9 % delineated sources. The average DISCERN score for information quality indicated good quality information (>3). The average PEMAT scores for Understandability and Actionability were 90.6 % and 86.6 %, respectively, which are good scores (≥75 %). CONCLUSIONS: Most free apps were functional and well received by users, however quality of app content varied. Only some apps had an informational component, and even fewer had sources listed. Providers recommending health apps should consider those that meet Xcertia guidelines, have reliable information, and have good understandability and actionability.

Structural, functional and molecular pathogenesis of pelvic organ prolapse in patient and Loxl1 deficient mice.

Pelvic organ prolapse is a worldwide health problem to elderly women. Understanding its pathogenesis and an ideal animal model are crucial to developing promising treatments. The present study aimed to investigate new clinical significance and detailed mechanism of pelvic organ prolapse by comparing the structural, functional and molecular dysfunctions of pelvic organ prolapse in patient and Loxl1 deficient mice. Our results showed that human vagina tissues from prolapsed site showed disarranged collagen and elastic fibers compared with the non-prolapse tissue. A gene ontology (GO) analysis of differentially expressed genes revealed molecular changes mainly related to inflammatory response and extracellular matrix (ECM) organization. While the mice lacking Loxl1 developed stable POP phenotype and disordered ECM structure in histology. Such Loxl1 knockout mice exhibited a significantly urinary dysfunction and decreased mechanical properties of the pelvic floor tissues, implying that POP in human condition might be induced by progressively decreased mechanics of pelvic tissues following ECM catabolism. Similarly, we not only identified significant up-regulated ECM catabolism processes and down-regulated ECM synthesis processes, but also characterized high level of inflammatory response in vagina tissue of the Loxl1 deficient mice. Thus, all these pathological changes in the POP mice model was consistent with those of the clinical elderly patients. These findings provide new insight into remodeling of POP by LOXL1 regulation and be of great importance to develop combination treatments of ECM metabolism and inflammation regulation strategy.

Symptomatic pelvic floor disorders and its associated factors in South-Central Ethiopia.

INTRODUCTION: Pelvic floor disorders (PFD) are gynecologic health problems containing a wide variety of clinical problems; the most prevalent problems are pelvic organ prolapse, fecal incontinence, and urinary incontinence. It is a significant women's health problem for both developed and developing countries. One in five women in Ethiopia experiences at least one major type of pelvic floor disorders. Despite the severity of the problem, due attention was not given, and no study has been conducted on pelvic floor disorders in the Gurage Zone. OBJECTIVE: To determine the prevalence and associated factors of symptomatic pelvic floor disorders among women living in Gurage Zone, SNNPR, Ethiopia, 2020. METHODOLOGY: Community-based cross-sectional study was conducted from February to March 2020 among 542 women residing in the Gurage Zone. A multi-stage sampling method was used to select the participants. Interviewer administered, pretested questionnaires containing questions related to pelvic organ prolapse, urinary, and fecal incontinence was used. The urinary incontinence severity index questionnaire was used to assess the severity of urinary incontinence. Epi-Info x7 was used to record data, and SPSS was used to analyze the data. Binary logistic regression with 95% CI was used to explore the relationship between PFD and other independent variables. After multivariable logistic regression analysis variables with P-value less than 0.05 was used to determine significant association. RESULT: A total of 542 participants were included in this study. Overall, 41.1% of the participants reported one or more symptoms of pelvic floor disorders. Urinary incontinence had the highest prevalence (32.8%), followed by pelvic organ prolapse (25.5%) and fecal incontinence (4.2%). History of weight lifting >10 Kg (AOR = 3.38; 95% CI: 1.99, 5.72), ≥5 vaginal delivery (AOR = 11.18; 95% CI: 1.53, 81.58), and being in menopause (AOR = 3.37; 95% CI: 1.40, 8.07) were identified as possible contributing factors in the development of a pelvic floor disorders. CONCLUSION: The prevalence of symptomatic PFD was higher compared to other similar studies in Ethiopia. Heavy weight lifting, repetitive vaginal deliveries and menopause were factors significantly associated with PFD. Expansion of technologies and building basic infrastructures, health education on kegel exercise and promotion of family planning should be considered as a prevention strategy.

Quantitative Morphometry of Elastic Fibers in Pelvic Organ Prolapse.

Pelvic organ prolapse (POP) is common among older women who have delivered children vaginally. While the pathophysiology is not fully delineated, POP can occur in part from insufficient repair of disrupted elastic matrix fibers. Quantification of structural changes to elastic fibers has not been described previously for POP. The goal of this paper is to present a validated technique for morphometric analysis of elastic fibers in vaginal tissue cultures from lysyl oxidase like-1 knock out (LOXL1 KO) mice with POP. The effect of LOXL1 KO, effect of POP, effect of culture, and effect of elastogenic treatment on the changes in elastin fiber characteristics were tested using vaginal tissues from wild type multiparous (WT), LOXL1 KO multiparous prolapsed (POP) and LOXL1 KO multiparous non-prolapsed (NP) mice. Our results show significantly higher mean aspect ratio, maximum diameter and perimeter length in POP compared to NP after 3 weeks of tissue culture. Further, treatment of POP tissues in culture with growth factors with previously documented elastogenic effects caused a significant increase in the mean area and perimeter length of elastic fibers. This technique thus appears to be useful in quantifying structural changes and can be used to assess the pathophysiology of POP and the effect of elastogenic treatments with potential for POP.

Mechanics of Uterosacral Ligaments: Current Knowledge, Existing Gaps, and Future Directions.

The uterosacral ligaments (USLs) are important anatomical structures that support the uterus and apical vagina within the pelvis. As these structures are over-stretched, become weak, and exhibit laxity, pelvic floor disorders such as pelvic organ prolapse occur. Although several surgical procedures to treat pelvic floor disorders are directed toward the USLs, there is still a lot that is unknown about their function. This manuscript presents a review of the current knowledge on the mechanical properties of the USLs. The anatomy, microstructure, and clinical significance of the USLs are first reviewed. Then, the results of published experimental studies on the in vivo and ex vivo, uniaxial and biaxial tensile tests are compiled. Based on the existing findings, research gaps are identified and future research directions are discussed. The purpose of this exhaustive review is to help new researchers navigate scientific literature on the mechanical properties of the USLs. The use of these structures remains very popular in reconstructive surgeries that restore and augment the support of pelvic organs, especially as synthetic surgical mesh implants continue to be highly controversial.

Role of Urodynamic Study in the Management of Pelvic Organ Prolapse in Women.

OBJECTIVES: Pelvic organ prolapse (POP) and lower urinary tract symptoms (LUTS) usually coexist and are common among women. Since the efficacy of urodynamic studies (UDS) in evaluating these conditions is subject to controversy, this study aimed to assess the accordance between urodynamic findings and LUTS and to determine the importance of UDS in women with POP. METHODS: This cross-sectional study was conducted on women over 18 years with symptomatic POP referred to the female urology clinic of Kerman University of Medical Sciences, Kerman, Iran, during 2017-2018. Patients who met the inclusion criteria were included in the study with informed consent. The Pelvic Floor Disability Index (PFDI-20) was completed for each patient. Pelvic examination was performed using the Pelvic Organ Prolapse Quantification System (POPQ). Subsequently, multi-channel UDS was performed, and the findings were analyzed in SPSS 20, using Chi-square or Fisher's test. RESULTS: A total of 200 women with symptomatic POP were included in the study. Stress, urge, and mixed urinary incontinence showed significant accordance with the urodynamic findings (urodynamic stress incontinence and/or detrusor overactivity). However, there was no significant relationship between urinary voiding LUTS and urodynamic findings. CONCLUSION: UDS should be performed for selective patients with POP. According to the results of the present study, UDS can help us provide consultation for POP patients with voiding LUTS. However, in POP patients with urinary incontinence, this test cannot provide further information and should be performed based on the patient's condition.

Relationship between symptomatic pelvic organ prolapse and respiratory muscle strength in middle-aged and older women in Northeast Brazil: a cross-sectional study.

Some respiratory muscles work in synergy with the pelvic floor (PF). Pelvic organ prolapse (POP) is characterized by weak PF muscles and has been associated with worse pulmonary ventilation function in women. To date no studies have investigated the association between respiratory muscle strength and POP. This study aimed to determine whether symptomatic POP is associated with respiratory muscle strength in middle-aged and older women. In this observational cross-sectional study, 204 community-dwelling women (41-80 years old) from Santa Cruz (Northeastern Brazil) provided information on socioeconomic characteristics, health behavior, reproductive history and symptomatic POP via a structured questionnaire. A digital manometer was used to measure their maximal inspiratory and expiratory pressures (MIP and MEP). Multiple linear regression analyses, adjusted for covariates (age, income, education, body mass index, and smoking), evaluated the association between POP and MIP/MEP. The results show that 14.7% of the sample reported symptomatic POP. These women exhibited lower mean MIP and MEP than those reporting no POP, but the intergroup difference was only significant for MEP (p = .01). The association between POP and MEP remained statistically significant, even after covariates (ß = 11.9, p = .04) were adjusted. Symptomatic POP is associated with expiratory muscle strength in middle-aged and older women. This innovative research provides important information regarding the need to evaluate the integrity of PF muscles when assessing respiratory muscle strength, which may help clinicians devise preventive and treatment strategies to improve women's health during the aging process.

Early postpartum physical activity and pelvic floor support and symptoms 1 year postpartum.

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

Anterior Vaginal Wall Prolapse Repair and the Rise and Fall of Transvaginal Mesh. Did We Come Full Circle? A Historical Perspective.

OBJECTIVE: To present a brief historical review of treatment options for pelvic organ prolapse with a focus on anterior vaginal wall defects and highlight changing practice patterns in the era of synthetic mesh controversy. METHODS: A MEDLINE and PubMed search was performed using the keywords pelvic organ prolapse, anterior colporrhaphy, and cystocele followed by a manual search of bibliographies. RESULTS: Ancient treatments included Hippocratic succession, local astringent, and use of pomegranates as crude pessaries. More sophisticated surgical techniques evolved in the 19th century with further refinement in the early 20th century. Numerous native tissue apposition techniques were popularized by Kelly, Kennedy, Burch, and Raz. Due to poor durability, surgeons sought alternate approaches including biologic and synthetic grafts. Synthetic transvaginal mesh (TVM) initially included use of Tantalum and Marlex to repair anterior wall defects. Both were eventually abandoned due to complications. TVM was re-designed, re-marketed, and re-introduced. Type 1 polypropylene monofilament TVM use became ubiquitous in female pelvic surgery peaking between 2004 and 2008. Initial promising outcomes were soon eclipsed by a surge of adverse events leading to multiple FDA warnings, reclassification to Class III, high-risk medical device, and ultimately a complete recall in 2019. CONCLUSION: The bidirectional pendulum swing on use of synthetic TVM has been occurring since its introduction 50 years ago. In the current era of mesh controversy, more practitioners are now revisiting previously described native tissue and biologic graft techniques. It appears that history has repeated itself.

Is pelvic floor muscle strength and thickness associated with pelvic organ prolapse in Nepali women? - A cross-sectional study.

BACKGROUND: Pelvic floor muscle function has been shown to be inversely associated with pelvic organ prolapse in Western women, however differences have been documented between ethnic groups. OBJECTIVE: To determine if pelvic floor muscle strength and thickness and hiatal area are associated with pelvic organ prolapse in Nepali women. METHODS: This cross-sectional study included non-pregnant Nepali women ≥18 years attending an outpatient gynecology clinic in Kathmandu, Nepal. A clinical examination included the pelvic organ prolapse quantification (POP-Q)- system examination and Modified Oxford Scale. Puborectalis muscle thickness and hiatal area were assessed using 3D/4D translabial ultrasound. Statistical analysis included Pearson's correlation and multiple regression (p<0.05). RESULTS: Of the 123 women; 14 (11%) had POP-Q stage 0 prolapse, 29 (24%) stage I, 69 (56%) stage II, 8 (7%) stage III, and 3 (2%) stage IV. Mean±SD Modified Oxford Scale was 3.37±0.48 and muscle thickness was 1.14±0.21cm, hiatal area at rest was 14.67±3.11cm2 and on contraction was 11.29±2.51cm2. No associations were found between pelvic floor muscle strength or thickness and POP-Q stages 0-IV. There was a positive correlation found between hiatal area at rest and pelvic organ prolapse stage (r=0.34, p<0.001)and hiatal area on contraction and prolapse stage (r=0.30, p<0.001) and a negative correlation between pelvic floor muscle strength and hiatal area on contraction (r=-0.36, p<0.001). CONCLUSION: In contrast to previous findings, pelvic floor muscle strength and thickness are not associated with pelvic organ prolapse in this sample of Nepali women. It is important to consider these findings when developing pelvic organ prolapse treatment and management strategies in this population.

Pelvic floor dysfunction distress is correlated with quality of life, but not with muscle function.

OBJECTIVE: To analyze the relationship between the symptoms of pelvic floor dysfunction (PFD) and quality of life (QoL), as well as the function of the pelvic floor muscle (PFM) in women with urinary incontinence (UI). METHODS: A cross-sectional study conducted in two centers in Brazil (Northeast and Southeast regions) with women with stress urinary incontinence (SUI) and mixed urinary incontinence (MUI). Data on pelvic floor symptoms, discomfort and impact on QoL were collected using the Pelvic Floor Distress Inventory-short form (PFDI-SF-20) and the Pelvic Floor Impact Questionnaire (PFIQ-7) instruments. PFM function was assessed by palpation (PERFECT scale) and manometry. Pearson's correlation test, analysis of variance (ANOVA) and the Student's t test were used to discriminate the differences, adopting a significance level of 5%. RESULTS: A total of 72 women participated in the study (mean age 51.7 ± 11.9 years). The presence and discomfort of pelvic floor symptoms (PFDI-SF-20) were correlated with QoL (PFIQ-7) (r = 0.52, p < 0.001). Deficits in PFM function (power and pressure) were observed, however, there was no correlation between these with the presence and discomfort of the pelvic floor symptoms (PFDI-SF-20). CONCLUSION: Greater discomfort due to PFD symptoms were correlated with a worse QoL. However, the relationship between symptoms and PFM function was not significant. These results reinforce the need to assess the aspects of activity and participation which compose functionality and QoL, and not only the PFM functions in women with UI.

Using the novel pelvic organ prolapse histologic quantification system to identify phenotypes in uterosacral ligaments in women with pelvic organ prolapse.

BACKGROUND: Pelvic organ prolapse is common, but the underlying etiologies are poorly understood, which limits our current prevention and treatment options. OBJECTIVE: Our primary objective was to compare the uterosacral ligament histologic features in women with and without prolapse using the novel pelvic organ prolapse histologic quantification system. Our secondary aim was to determine whether composite histologic findings in uterosacral ligaments are associated with prolapse risk factors. STUDY DESIGN: This was a prospective cohort study in which paracervical uterosacral ligament biopsies were performed at the time of hysterectomy for primary prolapse or other benign gynecologic indications and processed for histologic evaluation. The pelvic organ prolapse quantification system was used to determine the prolapse stage. In this study, 9 prominent histologic features were semiquantitatively scored using the pelvic organ prolapse histologic quantification system in a blinded fashion and compared between prolapse and control groups. Unbiased principal component analysis of these scores was independently performed to identify potential relationships between histologic measures and prolapse risk factors. RESULTS: The histologic scores of 81 prolapse and 33 control ligaments were analyzed. Compared with the control group, women in the prolapse group were significantly older and more likely to be in the menopausal phase. There was no difference in the number of vaginal deliveries, body mass index, hormone use, or smoking status between the groups. To control for baseline differences, patients were also stratified by age over 40 years and menopausal status. Compared with the control group, the prolapse ligaments in the premenopausal group had significantly more loss of smooth muscle fibers within the fascicles (P<.001), increased inflammatory infiltrates of neutrophils within the tissue and perineural inflammatory cells (P<.01 and P=.04, respectively), and reduced neointimal hyperplasia (P=.02). Prolapse ligaments in the postmenopausal group exhibited elevated adipose content compared with that of the control group (P=.05). Amount of fibrillar collagen, total nonvascular smooth muscle, and muscle fiber vesicles of prolapse ligaments did not differ in either the premenopausal or postmenopausal group compared with that of the control group. Unbiased principal component analysis of the histologic scores separated the prolapse ligaments into 3 phenotypes: (1) increased adipose accumulation, (2) increased inflammation, and (3) abnormal vasculature, with variable overlap with controls. Posthoc analysis of these subgroups demonstrated a positive correlation between increasing number of vaginal deliveries and body mass index with increasing adipose content in the adipocyte accumulation and inflammatory phenotype and increasing neointimal hyperplasia in the vascular phenotype. However, only the relationship between vaginal delivery and adipocytes was significant in the adipose phenotype (R2=0.13; P=.04). CONCLUSION: Histologic phenotypes exist in pelvic support ligaments that can be distinguished using the pelvic organ prolapse histologic quantification system and principle component analysis. Vaginal delivery is associated with aberrant adipose accumulation in uterosacral ligaments. Our findings support a multifactorial etiology for pelvic organ prolapse contributing to altered smooth muscle, vasculature, and connective tissue content in crucial pelvic support structures. To confirm these associations and evaluate the biomechanical properties of histologic phenotypes of prolapse, larger studies are warranted. Closing this gap in knowledge will help optimize personalized medicine and help identify targets for prevention and treatment of this complex condition.

Anterior-Apical Transvaginal Mesh (Surelift) for Advanced Urogenital Prolapse: Surgical and Functional Outcomes at 1 Year.

STUDY OBJECTIVE: To determine the objective and subjective outcomes of pelvic organ prolapse (POP) surgery using a modified Surelift system (Neomedic International, Barcelona, Spain) and to evaluate surgical complications and postoperative impact on quality of life (QOL) and lower urinary tract symptoms. DESIGN: Retrospective cohort study. SETTING: Tertiary-care university hospital. PATIENTS: Patients with symptomatic anterior or apical POP stage III and above. INTERVENTIONS: All patients underwent pelvic reconstructive surgery with a modified Surelift transvaginal mesh kit. MEASUREMENTS AND MAIN RESULTS: Eighty-three women who underwent pelvic reconstructive surgery with a modified Surelift for symptomatic anterior or apical prolapse stage III and above from April 2018 to January 2019 were reviewed retrospectively. All completed a 72-hour voiding diary, urodynamic study, and multiple validated QOL questionnaires at baseline and at between 6 and 12 months postoperatively. Descriptive statistics were used for demographics and perioperative data. Paired-samples t test and the McNemar test were applied for comparison of pre- and postoperative continuous and categoric data, respectively. The primary outcomes were the objective cure of POP, defined as anterior and apical prolapse Pelvic Organ Prolapse Quantification System ≤ stage I, and subjective cure on the basis of negative answers to Pelvic Organ Prolapse Distress Inventory 6. The objective and subjective cure rates at 1 year were 97.6% and 92.8%, respectively. There were significant improvements in QOL scores postoperatively. Although bladder outlet obstruction improved, de novo urodynamic stress incontinence and stress urinary incontinence were increased at 18.9% and 21.6%, respectively, at 1-year follow-up. The mesh extrusion rate was 4.8%. CONCLUSION: A modified Surelift has good objective and subjective cure rates at 1 year postoperatively with 4.8% mesh extrusion rate. There was significant improvement in lower urinary tract symptoms and QOL. De novo urodynamic stress incontinence at 6 months to 12 months was increased, but it was not sufficiently bothersome to warrant surgery.

Inter- and intrarater reliability of unidigital and bidigital vaginal palpation to evaluation of maximal voluntary contraction of pelvic floor muscles considering risk factors and dysfunctions.

AIMS: To evaluate inter- and intrarater reliability of unidigital and bidigital vaginal palpation of pelvic floor muscle (PFM) maximal voluntary contraction (MVC) according to PFM risk factors and dysfunctions. METHODS: A total of 187 women were recruited and evaluated by two examiners. Both performed the evaluation of MVC with unidigital and bidigital palpation, graded by Modified Oxford Scale. After 7-10 days, one examiner repeated the assessment. To analyze reliability by Cohen's linear Kappa (κw), participants were allocated into different groups according to: body mass index (BMI), menopause, parity, type of delivery and PFM dysfunctions, as pelvic organ prolapse (POP), constipation, urgency, urgency urinary incontinence, pelvic pain, and stress urinary incontinence. RESULTS: Inter-rater reliability of unidigital palpation was considered fair (κw = 0.21-0.40) to moderate (κw = 0.41-0.60) according to BMI, postmenopausal status, parity, type of delivery, and PFM dysfunctions. Inter-rater reliability of bidigital palpation varied from none (κw = 0.00-0.20) to moderate for all risk factors and PFM dysfunctions. Intra-rater reliability of unidigital palpation was considered fair only for women with POP (κw = 0.37) and moderate to substantial (κw = 0.61-0.80) to all other variables. Intra-rater reliability of bidigital palpation ranged from moderate to almost perfect (κw = 0.81-1.00). CONCLUSIONS: When performing vaginal palpation, physiotherapists must consider the way that is performing the evaluation, as some PFM risk factors and dysfunctions could influence the inter- and intrarater reliability of unidigital and bidigital palpation.

Immediate Postoperative Pelvic Organ Prolapse Quantification Measures and 2-Year Risk of Prolapse Recurrence.

OBJECTIVE: To assess whether resting genital hiatus, perineal body, and total vaginal length measured intraoperatively at the conclusion of surgery are associated with prolapse recurrence 2 years after native tissue pelvic organ prolapse reconstruction. METHODS: This ancillary analysis of the OPTIMAL (Operations and Pelvic Muscle Training in the Management of Apical Support Loss) trial included women who had an immediate postoperative pelvic organ prolapse quantification (POP-Q) examination and 2-year follow-up. Primary outcome was bothersome bulge symptoms. Secondary outcomes were anatomic failure, surgical failure (either anatomic failure or bothersome bulge symptoms), and sexual function. Descriptive statistics assessed relationships between postprocedure POP-Q measures and these four outcomes. Multivariable models were fit to the data to control for baseline differences in bivariate comparisons. Receiver operating characteristic curves were generated to identify an optimal genital hiatus cut point associated with bothersome bulge, and this threshold was explored. RESULTS: This analysis included 368 participants. Bivariate analyses identified age, body mass index, vaginal deliveries, baseline genital hiatus, perineal body, and advanced POP-Q stage (3 or higher vs 2) as clinically relevant variables to include in multivariable models. After adjusting for these variables, the association between immediate postoperative genital hiatus and bothersome bulge (adjusted odds ratio [aOR] 1.4; 95% CI 0.9-2.1) was not significant at the P<.05 level; however, immediate postoperative genital hiatus was associated with anatomic (aOR 1.6; 95% CI 1.1-2.3) and surgical failure (aOR 1.5; 95% CI 1.0-2.1). Immediate postoperative genital hiatus of 3.5 cm was the selected cutoff (area under the curve 0.58, 95% CI 0.50-0.66 from the bothersome bulge model). Women with genital hiatus 3.5 cm or greater were more likely to have anatomic and surgical failures at 2 years. No POP-Q measures were correlated with 2-year sexual function. CONCLUSION: A larger immediate postoperative genital hiatus measurement of 3.5 cm or greater is not associated with bothersome bulge symptoms or sexual dysfunction but is associated with anatomic and surgical failures 2 years after native tissue vaginal reconstructive surgery.

The clinical and urodynamic outcomes of single-incision mesh surgery using the Uphold system for the treatment of pelvic organ prolapse.

This retrospective cohort study aims to assess the clinical and urodynamic outcomes of single-incision mesh surgery with the Uphold system. The medical records of 140 women with anterior and/or apical compartment prolapse stage 2 or greater who underwent Uphold mesh surgeries were reviewed. The clinical evaluation included a pelvic examination, a urodynamic study (UDS), and a personal interview to evaluate lower urinary tract symptoms (LUTS). After a follow-up time of 12-30 months, the anatomical reduction rates were 100% and 96.4% for the apical and anterior compartments, respectively, and these rates were similar across women with or without hysterectomy. All of the LUTS and several UDS parameters improved significantly. The continence rate in women with stress urinary incontinence (SUI) was improved if they also underwent a mid-urethral sling (MUS) operation. However, the continence rate did not differ between women with and without occult urodynamic stress incontinence who did not undergo a concomitant MUS operation. The rate of vaginal mesh extrusion was 2.8%, and this complication rarely occurred beyond the learning curve. In conclusion, the anatomic correction of the Uphold system was satisfactory with a low rate of mesh extrusion. Women with SUI would benefit from a concomitant MUS operation.

Long-term Anatomical and Functional Results of Robot-Assisted Pelvic Floor Surgery for the Management of Multicompartment Prolapse: A Prospective Study.

BACKGROUND: Long-term data on robot-assisted sacrocolporectopexy for the treatment of multicompartment pelvic organ prolapse are scarce. With the rising prevalence of prolapse and increasing surgical repair, it is essential to evaluate long-term results. OBJECTIVE: This study aimed to evaluate long-term functional and anatomic outcomes after sacrocolporectopexy. DESIGN: This is a prospective, observational cohort study. SETTINGS: This study was conducted at a teaching hospital with tertiary referral function for patients with gynecological/rectal prolapse. PATIENTS: All patients undergoing robot-assisted sacrocolporectopexy from 2011 to 2012 were included. INTERVENTION: Robot-assisted sacrocolporectopexy was performed. MAIN OUTCOME MEASURES: The primary outcome was the anatomic cure rate after 1 and 4 years, defined as simplified pelvic organ prolapse quantification stage 1 vaginal apical prolapse and no external rectal prolapse or internal rectal prolapse present. Kaplan-Meier curves were used for determination of recurrence-free intervals. Secondary outcomes were functional pelvic floor symptoms (symptoms of bulge, obstructed defecation, fecal incontinence, urogenital distress inventory) and quality of life (Pelvic Floor Impact Questionnaire). RESULTS: Fifty-three patients were included. After 12 and 48 months, the recurrence-free intervals based on Kaplan-Meier estimates were 100% and 90%. In total, there were 10 recurrences: 2 apical and 8 internal rectal prolapses. Symptoms of bulge (94%-12%; p < 0.0005), fecal incontinence (62%-32%; p < 0.0005), obstructed defecation (59%-24%; p = 0.008), and median Pelvic Floor Impact Questionnaire scores (124-5; p = 0.022) improved significantly at final follow-up. Median urogenital distress inventory scores showed improvement after 1 year (30-13; p = 0.021). LIMITATIONS: This was an observational, single-center study with selective postoperative imaging. CONCLUSIONS: Ninety percent of patients were recurrence free 48 months after robot-assisted sacrocolporectopexy. Symptoms of vaginal bulge, quality of life, constipation, and fecal incontinence improved significantly. However, a subgroup of patients showed persistent bowel complaints that underlie the complexity of multicompartment prolapse. See Video Abstract at http://links.lww.com/DCR/B265.

The significance of pelvic floor support on the pelvic floor muscle functions of women with lower urinary tract symptoms.

OBJECTIVE: To explore the significance of pelvic organ prolapse (POP) on pelvic floor muscle (PFM) function among women with lower urinary tract symptoms (LUTS). MATERIALS AND METHODS: Four-dimensional ultrasound data of 577 women with LUTS were retrospectively analyzed. The bladder neck and genital hiatus were assessed during resting, coughing, and squeezing. The bladder neck location, genitohiatal size, and genitohiatal location were evaluated with bladder neck distance (BNd) and bladder neck angle (BNa), genitohiatal dimension (GHd) and genitohiatal area (GHAR), and genitohiatal angle (GHa), respectively. RESULTS: Compared with women without POP (n = 306), women with POP (n = 271) exhibited higher rates of levator complete avulsion (6.5% vs. 40.2%, P < 0.001), shorter BNd (2.84 ± 1.56 cm vs. 2.45 ± 0.45 cm, P = 0.018), larger BNa (92 ± 15° vs. 101 ± 21°, P < 0.001), longer GHd (5.25 ± 0.72 cm vs. 5.60 ± 0.87 cm, P < 0.001), larger GHa (141 ± 10° vs. 145 ± 9°, P = 0.004), and larger GHAR (20.0 ± 4.7 cm2 vs. 24.2 ± 5.6 cm2, P < 0.001) during resting. Fewer women with POP were able to maintain stable bladder neck location (79.5% vs. 65.5%, P < 0.001), genitohiatal size (60.7% vs. 51.9%, P = 0.042), and genitohiatal location (61.6% vs. 52.8%, P = 0.044) following coughing. Fewer women with POP were capable of squeezing (77.8% vs. 58.3%, P < 0.001). CONCLUSION: Among women with LUTS, the presence of POP is associated with weaker resting, involuntary, and voluntary PFM functions.

Comparison of Biaxial Biomechanical Properties of Post-menopausal Human Prolapsed and Non-prolapsed Uterosacral Ligament.

Uterosacral ligaments (USLs) provide structural support to the female pelvic floor, and a loss of USL structural integrity or biomechanical function may induce pelvic organ prolapse (POP). Alterations in extracellular matrix composition and organization dictate USL mechanical function. Changes in USL microstructure and corresponding mechanical properties, however, are not fully understood, nor is it understood how microstructure and mechanics change with onset and progression of POP. This is due, in part, as USL properties are primarily characterized along a single direction (uniaxial test), whereas the USL is loaded in multiple directions simultaneously within the body. Biaxial testing permits the acquisition of biomechanical data from two axes simultaneously, and thus simulates a more physiologic assessment compared to the traditional uniaxial testing. Therefore, the objective of this study was to quantify the biaxial biomechanical properties and histological composition of the USL in post-menopausal women with and without POP at various stages. Potential correlations between tissue microstructural composition and mechanical function were also examined. Tangential modulus was lower and peak stretch higher in POP III/IV compared to non-POP and POP I/II in the main in vivo loading direction; however, no significant differences in mechanical properties were observed in the perpendicular loading direction. Collagen content positively correlated to tangential modulus in the main in vivo loading direction (r = 0.5, p = 0.02) and negatively correlated with the peak stretch in both the main in vivo (r = -0.5, p = 0.02) and perpendicular loading directions (r = -0.3, p = 0.05). However, no statistically significant differences in USL composition were observed, which may be due to the small sample size and high variability of small sections of human tissues. These results provide first step towards understanding what microstructural and mechanical changes may occur in the USL with POP onset and progression. Such information may provide important future insights into the development of new surgical reconstruction techniques and graft materials for POP treatment.

Laparoscopic Long Mesh Surgery with Augmented Round Ligaments: A Novel Uterine Preservation Procedure For Apical Pelvic Organ Prolapse.

We aim to assess the surgical outcomes of our novel hysteropexy procedure, laparoscopic long mesh surgery (LLMS) with augmented round ligaments. Twenty-five consecutive women with stage II or greater main uterine prolapse defined by the POP quantification staging system were referred for LLMS. Long mesh is a synthetic T-shaped mesh, with the body fixed at the uterine cervix and the two arms fixed along the bilateral round ligaments. The clinical evaluations performed before and 6 months after surgery included pelvic examinations, urodynamic studies, and questionnaires for urinary and sexual symptoms. After a follow-up time of 12 to 24 months, the anatomical reduction rate was 92% (23/25) for the apical compartment. The average operative time was 65.4 ± 28.8 minutes. No major complications were recognized during LLMS. The lower urinary tract symptoms and scores on the questionnaires improved significantly after the surgery, except urgency urinary incontinence and nocturia. Neither voiding nor storage dysfunction was observed after the operations. All of the domains and total Female Sexual Function Index (FSFI) scores of the 15 sexually active women did not differ significantly after LLMS. The results of our study suggest that LLMS is an effective, safe, and time-saving hysteropexy surgery for the treatment of apical prolapse.
