Abstract
IMPORTANCE This study identifies key risk factors for pelvic organ prolapse (POP) in Korean women, providing valuable insights for prevention and personalized care. OBJECTIVES The aim of this study was to identify risk factors for POP in Korean women. STUDY DESIGN This retrospective case-control study analyzed 2003-2011 Korean health checkup data in postmenopausal women diagnosed with POP (cases) and age-matched controls without POP (1:4 ratio) to identify risk factors. RESULTS Of 2,506,271 participants, 34,648 patients were selected for the POP group and 138,592 patients were selected for the control group. The risk of POP was found to be increased with overweight (body mass index, 23-24.9: odds ratio [OR], 1.146; 95% confidence interval [CI], 1.1-1.196; body mass index, 25-29.9: OR, 1.142; 95% CI, 1.097-1.189) and multiple childbirths (2 times: OR, 1.52; 95% CI, 1.39-1.653; ≥3: OR, 1.639; 95% CI, 1.493-1.8). The risk of POP was found to be decreased with smoking (OR, 0.769; 95% CI, 0.688-0.861), alcohol drinking (3-6/week: OR, 0.65; 95% CI, 0.557-0.758), and exercise (1-2/week: OR, 0.904; 95% CI, 0.862-0.947; 3-4/week: OR, 0.896; 95% CI, 0.844-0.951; 5-6/week: OR, 0.87; 95% CI, 0.788-0.96). CONCLUSIONS This study found that overweight and multiple childbirths were associated with an increased risk of POP. Smoking, alcohol drinking, and exercise reduced the risk of POP, but socioeconomic status, age at menarche, and age at menopause were not found to be associated with POP.

Abstract
Pelvic floor dysfunction is a common problem in women and has a negative impact on their quality of life. The aim of this review was to provide a general overview of the current state of technology used to assess pelvic floor functionality. It also provides literature research of the physiological and anatomical factors that correlate with pelvic floor health. This systematic review was conducted according to the PRISMA guidelines. The PubMed, ScienceDirect, Cochrane Library, and IEEE databases were searched for publications on sensor technology for the assessment of pelvic floor functionality. Anatomical and physiological parameters were identified through a manual search. In the systematic review, 114 publications were included. Twelve different sensor technologies were identified. Information on the obtained parameters, sensor position, test activities, and subject characteristics was prepared in tabular form from each publication. A total of 16 anatomical and physiological parameters influencing pelvic floor health were identified in 17 published studies and ranked for their statistical significance. Taken together, this review could serve as a basis for the development of novel sensors which could allow for quantifiable prevention and diagnosis, as well as particularized documentation of rehabilitation processes related to pelvic floor dysfunctions.

Abstract
OBJECTIVES Urinary incontinence (UI) and pelvic organ prolapse (POP) are prevalent pelvic floor disorders (PFDs) among the female population. In the military environment, being a non-commissioned member (NCM), and physically demanding occupations are factors associated with higher PFD risk. This study seeks to characterize the profile of female Canadian Armed Forces (CAF) members reporting symptoms of UI and/or POP. METHODS Present CAF members (18-65 years) responded to an online survey. Only current members were included in the analysis. Symptoms of UI and POP were collected. Multivariate logistic regressions analyzed the relationships between PFD symptoms and associated characteristics. RESULTS 765 active members responded to female-specific questions. The prevalence of self-reported POP and UI symptoms were 14.5% and 57.0%, respectively, with 10.6% of respondents reporting both. Advanced age (adjusted odds ratio [aOR]: 1.062, CI 1.038-1.087), a body mass index (BMI) categorized as obese (aOR: 1.909, [1.183-3.081]), parity ≥1 (e.g., aOR for 1: 2.420, [1.352-4.334]) and NCMs (aOR: 1.662, [1.144-2.414]) were factors associated with urine leakage. Parity of ≥2 (aOR: 2.351, [1.370-4.037]) compared to nulliparous and having a perception of a physically demanding job (aOR: 1.933, [1.186-3.148]) were associated with experiencing POP symptoms. Parity of ≥2 increased the odds of reporting both PFD symptoms (aOR: 5.709, [2.650-12.297]). CONCLUSION Parity was associated with greater odds of experiencing symptoms of UI and POP. Higher age, higher BMI, and being an NCM were associated with more symptoms of UI, and the perception of having a physically demanding role increased the likelihood of reporting POP symptoms.

Relationship Between Maternal Age at First Delivery and Subsequent Pelvic Organ Prolapse. Female Pelvic Med Reconstr Surg 2021; 27:e423-e426. [PMID: 32910080 DOI: 10.1097/spv.0000000000000952] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To determine the relationship between age at first delivery and subsequent risk of pelvic organ prolapse. STUDY DESIGN We performed a retrospective cross-sectional study using the National Health and Nutrition Examination Survey data from 2005 to 2012. Our primary outcome was self-reported prolapse. Survival analyses and Cox proportional hazard models were used to estimate parous women's risks of reporting prolapse in terms of time since first delivery, adjusting for parity, body mass index, prior hysterectomy, ethnicity, and education. We performed subgroup analyses on women with at least 1 vaginal delivery and those with only cesarean deliveries. RESULTS The survey-weighted prevalence of prolapse was 2.82%. A total of 6203 women, 79% of all parous women surveyed, reported age at first delivery. Kaplan-Meier curves were different for women based on age at first delivery (P = 0.034). For each year increase in age at first delivery, there was a 6% increase in the rate of developing prolapse (adjusted hazard ratio, 1.06; 95% confidence interval, 1.01-1.11; P = 0.011). Compared with a woman who was 20 years at her first delivery, someone who was 30 years had 1.79 times the risk, while at 40 years the risk was 3.21 times. Among women with at least 1 vaginal delivery, the same relationship was found (adjusted hazard ratio, 1.06; 95% confidence interval, 1.01-1.12; P = 0.019). However, this was not significant for women with only cesarean deliveries (P = 0.367). CONCLUSIONS Older age at the time of first delivery was associated with a higher risk of subsequent prolapse. These results should be interpreted with caution given the limitations of cross-sectional survey data.

Abstract
OBJECTIVES This study aimed to investigate the prevalence of self-reported main pelvic floor disorders (PFD) (urinary incontinence [UI], pelvic organ prolapse [POP], and fecal incontinence [FI]) and its associated factors in women with premature ovarian insufficiency (POI) and a control group. METHODS This was a cross-sectional study wherein two groups were interviewed from August, 2017 to November, 2018-women with POI (n = 150) and a control group matched for age and body weight (n = 150). Sociodemographic variables and two questionnaires validated in Brazilian Portuguese language for PFD (Kings Health Questionnaire [KHQ] and Pelvic Floor Distress Inventory-20 [PFDI-20]) were used. Laycock's power, endurance, repetitions, fast contractions, every contraction timed (PERFECT) scale for pelvic floor muscle assessment was used in both groups. RESULTS The prevalence of self-reported UI was 27.33% and 37.33% for POI and control groups (P > 0.05), respectively. There was no perceived difference regarding the prevalence of POP (9.33% POI group vs 8% control group; P = 0.682) and FI (8% POI vs 4% control group; P = 0.145). The P (power) (P = 0.46), E (endurance) (P = 0.91), R (repetitions) (P = 0.88), and F (fast contractions) (P = 0.19) values were statistically similar in both the groups. Multivariate analysis (n = 141) showed that higher weight (odds ratio [OR] 1.047 [1.018-1.076]; P < 0.001) and gravidity rates (OR 1.627 [1.169-2.266]; P < 0.01) were risk factors for UI and higher weight (OR 1.046 [1.010-1.084]; P = 0.01), and presence of comorbidities (OR 8.75 [1.07-71.44]; P < 0.01) were risk factors for POP in the POI group; there was no variable that was associated with FI. CONCLUSIONS Women with POI did not have significant differences when compared with the control group regarding the prevalence of PFD and pelvic floor muscle assessment. Having higher weight and gravidity rates were associated with self-reported UI, while the presence of comorbidities and higher weight were risk factors for POP in the POI group. : Video Summary:http://links.lww.com/MENO/A555.

Abstract
BACKGROUND Pelvic organ prolapse can significantly affect a woman's quality of life by compromising physical, social, psychological and sexual function. Pelvic organ disorders and its consequences have higher economic burden to the patient as well to the country. Therefore, this systematic review and met- analysis aimed to estimate the burden of POP in Ethiopia. METHODS International databases (MEDLINE/Pub Med, Hinari, Scopus, Google scholar, African journals and literatures were searched and seven eligible cross sectional and two case control studies were included in this systematic review and meta-analysis. Eggers test and funnel plot were computed to check publication bias across the studies. Publication bias was computed using a funnel plot and eggers test. Heterogeneity of the studies was checked using Cochrane Q-test and I2 statistic. Subgroup analysis was computed for the evidence of heterogeneity. RESULTS This systematic review and meta-analysis revealed that the overall national prevalence of pelvic organ prolapse in Ethiopia was 23.52% (95% CI: 61.04, 80.24). Being rural resident (AOR = 3.29; 95% CI: 1.38-7.85), I2 = 47.5%, P = 0.167), having < 18.5 BMI (AOR = 2.59; 95% CI: 1.53-4.4), I2 = 59.9%, P = 0.64), and age > 40(AOR = 7.43; 95% CI: 2.27-24.29), I2 = 75.9%, P = 0.016) were the associated risk factors for pelvic organ prolapse. CONCLUSIONS The pooled prevalence of pelvic organ prolapse was high. Residence, body mass index and age of the women were the predictors of pelvic organ prolpase. Creating awareness and identifying the modifiable and non modifiable risk factors for pelvic organ prolpase is a crucial strategy to prevent further complications and risk of operation.

Abstract
Objective This study aimed to evaluate the correlation between obesity and pelvic organ prolapse (POP), both anatomically and symptomatically, in Korean women. Methods We retrospectively reviewed 476 women who visited the urogynecology clinic between January 2013 and December 2016. All the enrolled women were Korean. We sought to evaluate the relationship between obesity and POP, both anatomically and symptomatically, by using a validated tool. Anatomic assessment was performed by a standardized Pelvic Organ Prolapse Quantification (POP-Q) system and symptomatic assessment was performed by a Pelvic Floor Distress Inventory (PFDI)-20 questionnaire. Obesity measurement was performed by measuring body mass index (BMI). Results We enrolled 476 women in our study. There was no statistically significant correlation between BMI and POP-Q or PFDI-20 scores: Ba (P=0.633), Bp (P=0.363), C (P=0.277), Pelvic Organ Prolapse Distress Inventory-6 (P=0.286), Colorectal Anal Distress Inventory-8 (P=0.960), Urinary Distress Inventory-6 (P=0.355), and PFDI-20 (P=0.355). In addition, there was no statistically significant correlation between BMI and POP-Q or PFDI-20 in patients with severe (greater than stage III) POP. We also separately analyzed the differences in the POP-Q points and PFDI-20 scores between the obese and non-obese groups. There was no statistically significant difference between the groups. Conclusion We evaluated the correlation between obesity and POP using a validated tool. The present study revealed no significant correlation between obesity and POP severity anatomically or symptomatically in Korean women. This contrasts the results of most studies of Western women. Further studies in Asian women are required in order to confirm our results.

Comparison of Biaxial Biomechanical Properties of Post-menopausal Human Prolapsed and Non-prolapsed Uterosacral Ligament. Sci Rep 2020; 10:7386. [PMID: 32355180 PMCID: PMC7193612 DOI: 10.1038/s41598-020-64192-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2019] [Accepted: 03/28/2020] [Indexed: 11/10/2022] Open
Abstract
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.

Protease Inhibition Improves Healing of The Vaginal Wall after Obstetrical Injury: Results from a Preclinical Animal Model. Sci Rep 2020; 10:6358.

Abstract
Vaginal delivery with obstetrical trauma is a risk factor for pelvic organ prolapse later in life. Loss of fibulin-5 (FBLN5), an elastogenesis-promoting cellular matrix protein, results in prolapse in mice. Here, we evaluated effects of pregnancy, parturition, and obstetrical injury on FBLN5 content, elastic fibers, biomechanics, and histomorphology of the vaginal wall in rats. Further, we analyzed the effects of actinonin, a protease inhibitor, on obstetrical injury of the vaginal wall. Vaginal FBLN5 decreased significantly in pregnancy, and injury resulted in further downregulation. Stiffness of the vaginal wall decreased 82% in pregnant rats and 74% (p = 0.019) with injury relative to uninjured vaginal delivery controls at 3d. Actinonin ameliorated loss of FBLN5, rescued injury-induced loss of elastic fibers and biomechanical properties after parturition, and reduced the area of injury 10-fold. We conclude that pregnancy and parturition have a profound impact on vaginal FBLN5 and biomechanics of the vaginal wall. Further, obstetrical injury has significant deleterious impact on recovery of the vaginal wall from pregnancy. Actinonin, a non-specific matrix metalloprotease inhibitor, improved recovery of the parturient vaginal wall after obstetrical injury.

Abstract
OBJECTIVE The aim of this study was to evaluate the outcomes of women with advanced apical prolapse who were treated with the obliterative LeFort partial colpocleisis (LFC) procedure. MATERIALS AND METHODS We reviewed the medical records of patients who underwent LFC for advanced apical prolapse. We collected data for baseline patient characteristics, co-morbidities, severity of prolapse, operating time, intraoperative injuries, and postoperative complications. Subjective postoperative outcomes and patient satisfaction levels were also assessed. RESULTS Ninety-five patients underwent LFC during the study period. Median age of patients at operation was 76.0years. Mean operation time was 121.5 ± 31.9 min. Mean postoperative hospital stay was 3.5 ± 1.6 days. Postoperative complications, which were virtually all urinary symptoms, were present in 29.8% of patients, and 89.3% of patients have been in spontaneous remission. There was one case with perineal wound infection, one case of prolapse recurrence, and one case of de novo rectal prolapse after LFC. The objective success rate of the LFC procedure for all patients was 98.9% (94/95). Most (96%) patients were satisfied with the LFC results and pleased with the improvement in body image. CONCLUSION The obliterative LFC procedure had a high success rate and was associated with minimal adverse events for the elderly patients with advanced apical prolapse. This procedure should be considered as a treatment option for the advanced apical prolapse in selected elderly women who do not want to conserve vaginal intercourse, as it offers improvement in quality of life and is associated with a low regret rate.

Correlation Between Autophagy and Collagen Deposition in Patients With Pelvic Organ Prolapse. Female Pelvic Med Reconstr Surg 2019; 24:213-221. [PMID: 28786871 DOI: 10.1097/spv.0000000000000455] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/04/2023]
Abstract
OBJECTIVES The aim of this study was to explore the link between autophagy and collagen metabolism in patients with pelvic organ prolapse (POP) by detecting the expressions of autophagy factors, collagen, desmin, cytokeratin, and vimentin. METHODS Histology of anterior vaginal wall and uterosacral ligament was assessed by hematoxylin-eosin staining in POP and non-POP control patients (n = 50 per group). Expressions of collagen types I and III, LC3II, beclin 1, and p62 were examined by Western blot analysis. Expressions of LC3, vimentin, desmin, and cytokeratin were detected by immunohistochemical staining. A linkage between the mean of LC3 integrated option density summation (IOD SUM) and POP clinicopathologic parameters including Pelvic Organ Prolapse Quantification (POP-Q) staging, age, body mass index, gravidity, and parity was analyzed by χ test, respectively. RESULTS Compared with the control group, the following differences were found both in the vaginal wall and in the uterosacral ligament of the POP group: hematoxylin-eosin staining showed that collagen was more fragmented and disorganized. Expressions of collagen types I and III, LC3II, and beclin 1 were diminished, whereas the p62 level was elevated in Western blotting. Immunohistochemical staining showed that expression of LC3 was down-regulated, whereas vimentin level was increased. There were no significant differences in the expressions of desmin and cytokeratin in the 2 groups (P > 0.05). Mean of LC3 IOD SUM was highly linked to the POP-Q stage in the POP group (P < 0.05), whereas there was no significant correlation between the mean of LC3 IOD SUM and POP groups in age, body mass index, gravidity, and parity, respectively(P > 0.05). CONCLUSIONS Autophagic activity is impaired in the POP group, which may relate to collagen deposition.

Abstract
OBJECTIVE The objective of this study was to evaluate the overall outcomes and complication rates of the transvaginal mesh (TVM) placed for the management of pelvic organ prolapse (POP) at 5-years follow up. STUDY DESIGN Retrospective cohort study in Urogynecology section in a single center in Argentina. Patients with prolapse stage II or higher were included. Seventy-six patients had TVM surgery for POP and 72 (95%) were available for the 5-year follow-up period. RESULTS The cure rate using the combined criteria (leading edge ≤0 according to Pelvic Organ Prolapse Quantification System (POP-Q), no bulge symptoms and no new treatment for prolapse) was 79.2% (57/72) (95% CI 68-88%). Only 5.5% (4/72) (95% CI 1.5-13.6) were re-operated for prolapse recurrence. Mesh exposure occurred in 16.6% of cases (n = 12; 95%CI 8.9-27.3). The incidence of de-novo dyspareunia was 13.3% (2/15) (95%CI 1-40) CONCLUSIONS: We observed that TVM is a durable treatment for prolapse and that adverse events were acceptable without severe complications at 5-year follow-up.

Effects of mechanical stretching on the morphology of extracellular polymers and the mRNA expression of collagens and small leucine-rich repeat proteoglycans in vaginal fibroblasts from women with pelvic organ prolapse. PLoS One 2018; 13:e0193456. [PMID: 29630675 PMCID: PMC5890965 DOI: 10.1371/journal.pone.0193456] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2017] [Accepted: 02/12/2018] [Indexed: 01/12/2023] Open
Abstract
To determine the effect of mechanical stretching load and the efficacy of postmenopausal estrogen therapy (ET) on pelvic organ prolapse (POP), vaginal fibroblasts isolated from postmenopausal women with or without POP were subjected to 0.1-Hz uniaxial cyclic mechanical stretching (CS) with 10% elongation and 10-8 M 17-β-estradiol (E2) treatment. We investigated the morphological characteristics of extracellular polymers using scanning electron microscopy (SEM) and monitored the mRNA expression of type I collagen (COL I) and type III collagen (COL III) as well as the small leucine-rich proteoglycan (SLRP) family members decorin (DCN), biglycan (BGN), fibromodulin (FMO), and lumican (LUM), using real-time quantitative polymerase chain reaction (RT-PCR). Using SEM, certain viscoelastic polymers were found to be randomly distributed among fibroblasts, which for normal fibroblasts formed clusters of plum flower-like patterns under static-culture conditions and resembled stretched strips when stretched in culture, whereas polymers among POP fibroblasts resembled stretched strips under static-cultured conditions and presented broken networks when stretched in culture. RT-PCR revealed that COL I, DCN, BGN, FMO, and LUM mRNA expression was significantly higher in POP than in normal fibroblasts under static-culture condition. Following CS, COL I and BGN mRNA expression was significantly up-regulated in normal fibroblasts, and DCN and FMO mRNA expression was down-regulated in POP fibroblasts. Following concomitant CS and E2 treatment, significantly elevated COL I and DCN mRNA expression was observed in normal fibroblasts, and significantly elevated COL I and BGN mRNA expression was observed in POP fibroblasts. COL III mRNA expression was not significantly different between the POP and normal group, and CS did not significantly affect expression in either group, though COL III was down-regulated in normal fibroblasts concomitantly treated with E2 and CS. We conclude that the morphological distribution of extracellular polymers in POP fibroblasts exhibited higher sensitivity and lower tolerance to stretching loads than do normal fibroblasts. These mechanical properties were further reflected in the transcription of COL I. Defects in the compensatory function of BGN for DCN and LUM for FMO exist in POP fibroblasts, which further affect the structure and function of COL I in response to stretching load, ultimately resulting in abnormal reconstruction of pelvic supportive connective tissues and the occurrence of POP. ET can maintain stretching-induced elevations in COL I and DCN transcription in healthy women and improve stretching-induced COL I, DCN, BGN, and FMO transcriptional changes in POP women to prevent and improve POP. Only down-regulated COL III transcription was observed upon concomitant CS and E2 treatment in normal fibroblasts, which suggests that the tensile strength, not the elasticity, of the supportive connective tissues is damaged in POP and that the higher tensile strength induced by ET in healthy fibroblasts prevents POP. These findings confirm the role of higher sensitivity and lower tolerance to mechanical stretching in the pathogenesis of POP and further provide evidence supporting the use of ET to prevent and inhibit POP in postmenopausal women.

Abstract
BACKGROUND Studies evaluating the association between obesity and pelvic organ prolapse report estimates that range from negative to positive associations. Heterogeneous definitions for pelvic organ prolapse and variable choices for categorizing obesity measures have made it challenging to conduct meta-analysis. OBJECTIVE We systematically evaluated evidence to provide quantitative summaries of association between degrees of obesity and pelvic organ prolapse, and identify sources of heterogeneity. STUDY DESIGN We searched for all indexed publications relevant to pelvic organ prolapse up until June 18, 2015, in PubMed/MEDLINE to identify analytical observational studies published in English that reported risk ratios (relative risk, odds ratio, or hazard ratio) for body mass index categories in relation to pelvic organ prolapse. Random effects meta-analyses were conducted to report associations with pelvic organ prolapse for overweight and obese body mass index categories compared with women in the normal-weight category (referent: body mass index <25 kg/m2). RESULTS Of the 70 studies that reported evidence on obesity and pelvic organ prolapse, 22 eligible studies provided effect estimates for meta-analysis of the overweight and obese body mass index categories. Compared with the referent category, women in the overweight and obese categories had meta-analysis risk ratios of at least 1.36 (95% confidence interval, 1.20-1.53) and at least 1.47 (95% confidence interval, 1.35-1.59), respectively. Subgroup analyses showed effect estimates for objectively measured clinically significant pelvic organ prolapse were higher than for self-reported pelvic organ prolapse. Other potential sources of heterogeneity included proportion of postmenopausal women in study and reported study design. CONCLUSION Overweight and obese women are more likely to have pelvic organ prolapse compared with women with body mass index in the normal range. The finding that the associations for obesity measures were strongest for objectively measured, clinically significant pelvic organ prolapse further strengthens this evidence. However, prospective investigations evaluating obesity and pelvic organ prolapse are few.

Abstract
Pelvic organ prolapse (POP) is a major health problem that affects many women with potentially severe physical and psychological impact as well as impact on their daily activities, and quality of life. Several surgical techniques have been proposed for the treatment of POP. The FDA has published documents that refer to concerns about the use of synthetic meshes for the treatment of prolapse, in view of the severe complications that may occur. These led to hesitancy in use of these meshes and partial increase in use of other biological grafts such as allografts and xenografts. Although there seems to be an increasing tendency to use grafts in pelvic floor reconstructive procedures due to lower risks of erosion than synthetic meshes, there are inconclusive data to support the routine use of biological grafts in pelvic organ prolapse treatment. In light of these observations new strategies are needed for the treatment of prolapse. Platelet rich plasma (PRP) is extremely rich in growth factors and cytokines, which regulate tissue reconstruction and has been previously used in orthopaedics and plastic surgery. To date, however, it has never been used in urogynaecology and there is no evidence to support or oppose its use in women who suffer from POP, due to uterine ligament defects. PRP is a relatively inexpensive biological material and easily produced directly from patients' blood and is, thus, superior to synthetic materials in terms of potential adverse effects such as foreign body reaction. In the present article we summarize the existing evidence, which supports the conduct of animal experimental and clinical studies to elucidate the potential role of PRP in treating POP by restoring the anatomy and function of ligament support.

Abstract
Introduction Pelvic organ prolapse (POP) is a significant public health problem in developing countries including Ethiopia. However, less has been documented on risk factors of POP. Therefore, the aim of this study was to identify the determinants factors of POP. Methods An unmatched case–control study was conducted among gynecologic patients in Bahir Dar city, North West Ethiopia, from July to October 2014. A total of 370 women (selected from outpatient departments) were included in the study. Cases (clients with stage III or IV POP) and controls (who declared free of any stages of POP) were identified by physicians using the Pelvic Organ Prolapse Quantitative Examination tool. Data analysis was carried out by SPSS version 20.0. Descriptive, bivariate, and multivariable logistic regression analyses were performed. Statistical differences were considered at P<0.05, and the strength of association was assessed by odds ratio (OR) and respective confidence intervals (CIs). Results This study revealed that determinants such as age of women (>40 years) (adjusted OR [AOR] =3.0 [95% CI: 1.59–5.89]), sphincter damage (AOR =8.1 [95% CI: 1.67–39.7]), family history of POP (AOR =4.9 [95% CI: 1.94–12.63]), parity (≥4) (AOR =4.5 [95% CI: 2.26–9.10]), nonattendance of formal education (AOR =4.3 [95% CI: 1.25–14.8]), carrying heavy objects (AOR =3.1 [95% CI: 1.56–6.30]), body mass index (BMI) <18.5 kg/m2 (AOR =3.1 [95% CI: 1.22–7.82]), and delivery assisted by nonhealth professionals (AOR =2.6 [95% CI: 1.24–5.56]) were significantly associated with POP. Conclusion In our study, sphincter damage, family history of POP, being uneducated, having ≥4 vaginal deliveries, carrying heavy objects, BMI <18.5 kg/m2, age ≥40 years, and having delivery assisted by nonhealth professional were the independent determinants of POP. Therefore, skilled delivery, further promoting family planning and girls’ education, early pelvic floor assessment, and counseling on avoidance of carrying heavy objects are recommended.

Abstract
OBJECTIVES Pelvic organ prolapse (POP) is a major health problem that impairs the quality of life with a wide clinical spectrum. Since the uterosacral ligaments provide primary support for the uterus and the upper vagina, we hypothesize that the disruption of these ligaments may lead to a loss of support and eventually contribute to POP. DESIGN AND METHODS In this study, we therefore investigated whether there are any differences in the transcription profile of uterosacral ligaments in patients with POP when compared to those of the control samples. Seventeen women with POP and 8 non-POP controls undergoing hysterectomy for benign conditions were included in the study. Affymetrix® Gene Chip microarrays (Human Hu 133 plus 2.0) were used for whole genome gene expression profiling analysis. RESULTS There was 1 significantly down-regulated gene, NKX2-3 in patients with POP compared to the controls (p=4.28464e-013). KIF11 gene was found to be significantly down-regulated in patients with ≥3 deliveries compared to patients with <3 deliveries (p=0.0156237). UGT1A1 (p=2.43388e-005), SCARB1 (p=1.19001e-006) and NKX2-3 (p=2.17966e-013) genes were found to be significantly down-regulated in the premenopausal patients compared to the premenopausal controls. UGT1A1 gene was also found to be significantly down-regulated in the post menopausal patients compared to the postmenopausal controls (p=0.0005). CONCLUSION This study provides evidence for a significant down-regulation of the genes that take role in cell cycle, proliferation and embryonic development along with cell adhesion process on the development of POP for the first time.

Abstract
INTRODUCTION Vaginal vault prolapsus is a challenging problem for the patients and physicians. There may be differences between young and elderly patients in terms of efficiency and safety of surgical procedures. AIM The aim of our study was to compare the efficiency of the Posterior Intravaginal Sling (PIVS) procedure in older versus younger patient groups. MATERIALS AND METHODS A total of 40 patients who underwent the PIVS procedure were chosen. Twenty of these patients were younger than 60 years of age (Group I) while the other 20 patients were 60 years of age or older (Group II). Preoperative Pelvic Organ Prolapsed Quantification (POP-Q) reference points were compared with postoperative data at the first year following surgery. Student's t-test was used to analyse continuous variables and the χ(2) test was used to analyse categorical data. The Mann-Whitney test was used for data that were not normally distributed. RESULTS Anatomical cure rates were 90 percent in both groups (p=1.00). There were significantly greater improvements in POP-Q points in group I than group II. CONCLUSION It could be concluded that PIVS as minimally invasive procedure for vaginal vault prolapsed and is effective in all age groups.

Abstract
OBJECTIVES To explore the clinical importance and surgical outcomes of Green type III cystocele in women with anterior vaginal prolapse. METHODS A database of 336 women with a Ba point higher than -3 cm on the Pelvic Organ Prolapse Quantification system was retrospectively reviewed. Investigated data comprised those obtained from a clinical interview, the Pelvic Organ Prolapse Quantification system, and sonography. Initially, the baseline data between women with (n = 126) and without (n = 210) Green type III cystocele on sonography were compared. Subsequently, 6-month postoperative data between women who had Green type III cystocele on sonography and underwent either anterior colporrhaphy (n = 25) or a Perigee procedure (n = 76) were compared. RESULTS Women with Green type III cystocele had symptoms of voiding dysfunction more frequently, stress urinary incontinence less frequently, and more bulging (mean ± SD, 2.7 ± 1.2 versus 1.9 ± 1.5 for women with versus without Green type III cystocele; P = .001), a greater likelihood of stage II or higher cystocele (86.5% versus 60.0% for women with versus without Green type III cystocele; P < .001), as well as more caudodorsal bladder neck and genitohiatal positions and a wider genital hiatus on sonography. Women with Green type III cystocele had a greater likelihood of stage 0 cystocele (64.0% versus 89.5% for anterior colporrhaphy versus Perigee; P< .001) and more ventral bladder neck positions after Perigee procedures. CONCLUSIONS The presence of Green type III cystocele in women with anterior vaginal prolapse is associated with more functional impairments and anatomic defects. Despite comparable functional outcomes, Perigee procedures provide better anatomic outcomes for the anterior vagina in women with Green type III cystocele than anterior colporrhaphy does in the short term.

Abstract
BACKGROUND Uterine prolapse is a common problem among women in developing countries. It is known to cause physical and psychosocial problems affecting the quality of life of patients. This study was done to determine the risk factors, clinical features, and management practices in uterine prolapse (UP). METHODS A review of 350 case records of UP cases admitted between 2009 and 2014 was done in tertiary care hospitals. RESULTS Mean age at presentation of UP was 52.8 ± 13.2 years. Majority of cases were manual laborers [232 (78.6 %)]. Obstetric factors like parity ≥5 times [78 (22.3 %)], age at last pregnancy between 30 and 39 years (57.2 %), inadequate birth spacing (57.8 %), home deliveries [162 (58.3 %)], deliveries conducted by untrained personnel (25.3 %), vaginal deliveries (89.7 %), prolonged duration of labor (21.6 %), and heavy work in post natal period (29.8 %) were observed among cases. Correlation between age of presentation of prolapse with age at first and last pregnancy was significant. Most common associated complaint among UP cases was pain abdomen [55 (15.7 %)] and difficulty in micturition [51 (14.6 %)]. Majority were cases of third-degree prolapse [269 (76.8 %)]. Most common associated organ prolapse was cystocele [261 (74.6 %)]. The most common operative procedure done was vaginal hysterectomy, and conservative procedure was ring pessary application. CONCLUSION Public awareness on reduction in family size, support for institutional-based delivery by trained personnel, and adequate rest and exercises in early post natal period is required to minimize the occurrence of UP.

Glob Health Action 2015; 8:28771. [PMID: 26265389 PMCID: PMC4532727 DOI: 10.3402/gha.v8.28771] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2015] [Revised: 07/13/2015] [Accepted: 07/13/2015] [Indexed: 11/14/2022] Open
Abstract
Background Uterine prolapse (UP) is a reproductive health problem and public health issue in low-income countries including Nepal. Objective We aimed to identify the contributing factors and stages of UP and its impact on quality of life in the Jhaukhel–Duwakot Health Demographic Surveillance Site of Bhaktapur, Nepal. Design Our three-phase study used descriptive cross-sectional analysis to assess quality of life and stages of UP and case–control analysis to identify contributing factors. First, a household survey explored the prevalence of self-reported UP (Phase 1). Second, we used a standardized tool in a 5-day screening camp to determine quality of life among UP-affected women (Phase 2). Finally, a 1-month community survey traced self-reported cases from Phase 1 (Phase 3). To validate UP diagnoses, we reviewed participants’ clinical records, and we used screening camp records to trace women without UP. Results Among 48 affected women in Phase 1, 32 had Stage II UP and 16 had either Stage I or Stage III UP. Compared with Stage I women (4.62%), almost all women with Stage III UP reported reduced quality of life. Decreased quality of life correlated significantly with Stages I–III. Self-reported UP prevalence (8.7%) included all treated and non-treated cases. In Phase 3, 277 of 402 respondents reported being affected by UP and 125 were unaffected. The odds of having UP were threefold higher among illiterate women compared with literate women (OR=3.02, 95% CI 1.76–5.17), 50% lower among women from nuclear families compared with extended families (OR=0.56, 95% CI 0.35–0.90) and lower among women with 1–2 parity compared to >5 parity (OR=0.33, 95% CI 0.14–0.75). Conclusions The stages of UP correlated with quality of life resulting from varied perceptions regarding physical health, emotional stress, and social limitation. Parity, education, age, and family type associated with UP. Our results suggest the importance of developing policies and programs that are focused on early health care for UP. Through family planning and health education programs targeting women, as well as women empowerment programs for prevention of UP, it will be possible to restore quality of life related to UP.

Effects of mechanical stretching on the morphology and cytoskeleton of vaginal fibroblasts from women with pelvic organ prolapse. Int J Mol Sci 2015; 16:9406-19. [PMID: 25923074 PMCID: PMC4463595 DOI: 10.3390/ijms16059406] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2014] [Revised: 03/04/2015] [Accepted: 04/08/2015] [Indexed: 01/03/2023] Open
Abstract
Mechanical load and postmenopausal hypoestrogen are risk factors for pelvic organ prolapse (POP). In this study, we applied a 0.1-Hz uniaxial cyclic mechanical stretching (CS) with 10% elongation and 10−8 M 17-β-estradiol to vaginal fibroblasts isolated from postmenopausal women with or without POP to investigate the effects of CS and estrogen on cell morphology and cytoskeletons of normal and POP fibroblasts. Under static culture condition, POP fibroblasts exhibited lower cell circularity and higher relative fluorescence intensities (RFIs) of F-actin, α-tubulin and vimentin. When cultured with CS, all fibroblasts grew perpendicular to the force and exhibited a decreased cell projection area, cell circularity and increased cell length/width ratio; normal fibroblasts exhibited increased RFIs of all three types of cytoskeleton, and POP fibroblasts exhibited a decreased RFI of F-actin and no significant differences of α-tubulin and vimentin. After being cultured with 17-β-estradiol and CS, normal fibroblasts no longer exhibited significant changes in the cell projection area and the RFIs of F-actin and α-tubulin; POP fibroblasts exhibited no significant changes in cell circularity, length/width ratio and F-actin even with the increased RFIs of α-tubulin and vimentin. These findings suggest that POP fibroblasts have greater sensitivity to and lower tolerance for mechanical stretching, and estrogen can improve the prognosis.

Abstract
OBJECTIVE This study aims to estimate the effects of bilateral salpingo-oophorectomy (BSO) at the time of hysterectomy and estrogen therapy on vaginal prolapse. METHODS A retrospective analysis of the Women's Health Initiative estrogen-alone trial was performed. Women who retained their ovaries were compared with women who had BSO at the time of hysterectomy for the presence of cystocele or rectocele at entry into the study. Based on BSO and hormone therapy (HT) status, participants were categorized into groups. We hypothesized that BSO and prolonged hypoestrogenemia may be associated with an increased risk of prolapse. Univariate and multivariate analyses were used to determine the effects of BSO and HT status on cystocele and rectocele. RESULTS Of 10,739 participants in the estrogen-alone trial, 8,879 women were included in the analysis. Older age, higher parity, higher body mass index, higher waist-to-hip ratio, and non-African-American race/ethnicity were associated with increased odds of developing cystocele or rectocele. Women who retained their ovaries had higher rates of cystocele or rectocele at screening (39%) compared with all women who had BSO (31-36%; odds ratio, 1.18; 95% CI, 1.04-1.33). After controlling for multiple variables, our analysis showed that women who retained their ovaries had higher odds of developing cystocele or rectocele compared with women who had BSO and no subsequent HT (odds ratio, 1.23; 95% CI, 1.07-1.41). All other comparisons were nonsignificant. CONCLUSIONS BSO at the time of hysterectomy is not associated with increased risk of cystocele or rectocele. BSO and no subsequent HT may even have a protective effect against cystocele or rectocele.

Abstract
OBJECTIVE To determine the association between mode of delivery, parity, and pelvic organ prolapse, as assessed by the pelvic organ prolapse quantification system. DESIGN Cross-sectional study. SETTING Tertiary referral center, Turkey. POPULATION A total of 1964 women with benign gynecological disorders who presented between October 2009 and July 2011. METHODS Evaluation using the pelvic organ prolapse quantification system and questionnaire assessing previous obstetrics and medical history. MAIN OUTCOME MEASURES Difference in pelvic organ prolapse stages between nulliparous and multiparous women, impact of parity and mode of delivery. RESULTS In the study population, 86.4, 7.2 and 6.4% had pelvic organ prolapse of stages 0-I, II, and III-IV, respectively, and 7.9% had significant prolapse beyond the hymen. The mean age, parity, and number of vaginal deliveries were significantly higher in the prolapse than in the non-prolapse group. Vaginal delivery was associated with an odds ratio of 2.92 (95% confidence interval 1.19-7.17) for prolapse when compared with nulliparity. Each vaginal delivery increased the risk of prolapse (odds ratio 1.23; 95% confidence interval 1.12-1.35) after controlling for all confounding factors. Cesarean delivery had no impact on the odds for prolapse. CONCLUSIONS Vaginal delivery was an independent risk factor for prolapse, and additional vaginal deliveries significantly increased the risk. However, cesarean delivery had no effect on the development of prolapse in this material.

Abstract
Background Smoking is a modifiable lifestyle factor that has been shown to be associated with adverse perinatal outcomes and to have adverse health and dose-dependent connective tissue effects. The objective of this study was to examine whether smoking during pregnancy was associated with the incidence of obstetric anal sphincter injuries (OASIS) among six birthweight groups in singleton vaginal deliveries, considering nulliparous and multiparous women separately between 1997 and 2007 in Finland. Methodology A retrospective population-based register study. Populations included women with spontaneous singleton vaginal deliveries, consisting of all 213,059 nulliparous and all 288,391 multiparous women. Incidence of OASIS (n = 2,787) between smoking status groups was adjusted using logistic regression analyses. Principal Findings Of the nulliparous women, 13.1% were smokers, 3.6% had given up smoking during the first trimester of their pregnancy and 81.1% were non-smokers. Among these groups 0.7%, 0.9% and 1.1%, respectively suffered OASIS (p≤0.001). Nulliparous women who smoked had a 28% (95% CI 16–38%, p≤0.001) lower risk of OASIS compared to non-smokers, when adjusting for background variables. In multiparous women, the overall frequencies of OASIS were much lower (0.0–0.2%). A similar inverse relationship between OASIS rates and smoking was significant in pooled univariate analysis of multiparous women, but multivariate analysis revealed statistically insignificant results between non-smokers and smokers. Conclusions Nulliparous women who were smokers had a 28% lower incidence of OASIS. However, smoking during pregnancy cannot be recommended since it has shown to be associated with other adverse pregnancy outcomes and adverse health effects. The observed association warrants clinical repetition studies and, if confirmed, also in vitro studies focusing on connective tissue properties at a molecular and cellular level.

Abstract
The present study investigated the morphology and structure of pelvic floor in 50 nulliparous and 50 pelvic organ prolapse (POP) women using translabial three-dimensional (3D) ultrasound. The levator hiatus in POP women was significantly different from that in nullipara women. In POP women, the size of pelvic floor increased, with a circular shape, and the axis of levator hiatus departed from the normal position in 36 (72%) cases. The puborectalis was avulsed in 18 (36%) cases and the pelvic organs arranged abnormally in 23 (46%) cases. In summary, 3D ultrasound is an effective tool to detect the pelvic floor in POP women who presented with abnormalities in the morphology and structure of pelvic floor.

Abstract
AIM To evaluate whether the presence of specific polymorphism in the gene promoter of collagen and some matrix metalloproteinases was associated with the risk of developing pelvic organ prolapse. METHODS A case-control study was carried on 233 women: 137 were cases with ≥ stage II pelvic organ prolapse and 96 were matched controls without pelvic pathologies. Allele and genotype frequencies related to polymorphisms at the Sp1 site of type I collagen and some functional polymorphisms in the promoters of metalloproteinases-1, -3 and -9 have been compared between groups. It has been shown that these single-insertions/deletions polymorphisms located in the promoter region of the genes have a functional significance in the regulation of their transcriptional level and local expression. Genotypes were determined by polymerase chain reaction (PCR) amplification and sequence analysis. SPSS 14.0 software was used for data analysis. Probability values of <0.05 were considered statistically significant. RESULTS No difference between groups was found in the genotype distribution polymorphisms for COL1A1, metalloproteinases-9 and -3, while the distribution of the polymorphism of metalloproteinases-1 was significantly increased in the cases when compared with controls (p = 0.04). CONCLUSIONS Our findings suggest that the polymorphism of metalloproteinases-1 might have a role in mediating susceptibility to pelvic organ prolapse.

Abstract
Pelvic floor disorders (PFDs) such as stress urinary incontinence (SUI) and pelvic organ prolapse (POP) may share a common pathophysiological process related to pelvic floor tissue laxity and loss of support. We reviewed recent literature on observed biochemical changes in women with SUI and POP, linking them to genetic predisposition. We found that studies of pelvic tissues showed differences between control subjects and women with POP and SUI in collagen and elastin structure at a molecular and fibrillar level. Studies were heterogeneous but showed a trend towards decreased collagen and elastin content. The contribution of matrix metalloproteinases to increased collagenolysis can be related to genetic polymorphisms present in higher frequency in women with PFD. Extracellular matrix (ECM) protein turnover plays a role in the development of POP and SUI, but much remains to be understood of this complex dynamic interplay of enzymes, proteins and molecules. Genotyping of candidate genes participating in ECM formation will elucidate the missing link between the manifestation of the disease and the biochemical changes observed systematically, in addition to those in the pelvic floor.

Abstract
Introduction and hypothesis This study aimed to determine the relationship of recurrent cystocele with avulsion of puborectalis muscle and other risk factors. Methods In this prospective observational cohort study, 245 women undergoing anterior colporrhaphy were invited for a 2-year follow-up visit consisting of a questionnaire, physical examination, and translabial 3D ultrasonography. Women with and without recurrent cystocele were compared to identify recurrence risk factors. Results Of the 245 women, 156 agreed to the follow-up visit (63.7%). Objective recurrence rate was 80 of 156 (51.3%). Seventeen of the 156 (10.9%) reported subjective recurrence. Risk factors for anatomical recurrence were complete avulsion of puborectalis muscle (OR, 2.4; 95% CI, 1.3, 4.7), advanced preoperative stage (OR, 2.0; 95% CI, 1.0, 4.1), family history of prolapse (OR, 2.4; 95% CI, 1.2, 4.9), and sacrospinous fixation (OR, 6.5; 95% CI, 2.0, 21.2). Conclusions Risk factors for anatomical cystocele recurrence after anterior colporrhaphy were complete avulsion of puborectalis muscle, advanced preoperative stage, family history of prolapse, and sacrospinous fixation.

Abstract
OBJECTIVE To evaluate the effect of selective estrogen receptor modulators and ethinyl estradiol on the biomechanical and biochemical properties of the uterosacral and round ligaments in the monkey model of menopause. STUDY DESIGN A randomized, double-blind, placebo-controlled study on 11 female macaque monkeys. Ovariectomized monkeys received 12 weeks of placebo, raloxifene, tamoxifen, or ethinyl estradiol. Biomechanical step-strain testing and real-time polymerase chain reaction was performed on the uterosacral and round ligaments. RESULTS Tamoxifen and raloxifene uterosacrals expressed differing collagen I/III receptor density ratios, but both selective estrogen receptor modulators showed decreased tensile stiffness compared to ethinyl estradiol and controls. CONCLUSION These findings support a possible effect of selective estrogen receptor modulators on biomechanical and biochemical properties of uterosacrals. This may play a role in pelvic organ prolapse.

Abstract
OBJECTIVE Homeobox genes are transcriptional regulators that orchestrate embryonic development. The HOXA13 gene is responsible for the development of the vagina and regulates extracellular matrix constituents. We hypothesized that vaginal expression of HOXA13 may be decreased in women with pelvic organ prolapse (POP) and sought to determine if hypoestrogenism affects its expression. METHODS Biopsy specimens were obtained from the anterior apex of the vagina from women with and without POP. Immunohistochemistry and real-time polymerase chain reaction were used to determine HOXA13 expression in premenopausal controls, in premenopausal women receiving leuprolide acetate, and in premenopausal and postmenopausal women with POP. RESULTS HOXA13 was expressed in all specimens. HOXA13 expression was 14-fold lower in premenopausal women with prolapse than in premenopausal controls (P < 0.001). In both POP groups, HOXA13 expression was lower than in the leuprolide group (P <or= 0.001). There were no differences in HOXA13 expression between premenopausal controls and women treated with leuprolide acetate (P = 1.0) or between the premenopausal and postmenopausal POP group (P = 1.0). CONCLUSIONS Vaginal HOXA13 expression is diminished in women with POP compared with women with normal support. In women with POP, expression of HOXA13 was not affected by menopause. Expression of HOXA13 was also not affected by exposure to leuprolide acetate, suggesting that estrogen and HOXA13 work through separate pathways in the extracellular matrix metabolism of the vagina. Understanding genetic predispositions to developing POP may identify younger patients at risk who may benefit from preventive strategies such as weight loss or smoking cessation and not necessarily from estrogen therapy.

Abstract
Pelvic organ prolapse (POP) is a common, debilitating disorder affecting millions of women. Uterosacral ligaments (USLs) are the main supportive structures of the uterus and vagina and are often attenuated in women with POP. Although the mechanical strength of USLs is known to be dependent on collagen synthesis and catabolism and the degradation protein MMP2 has been implicated in POP, the molecular mechanisms involved in the development of POP are currently unknown. Homeobox (HOX) genes are transcriptional regulators that orchestrate embryonic development of the urogenital tract. We demonstrated here that HOXA11 was essential for organogenesis of the USL by showing that USLs were absent in Hoxa11-null mice. We compared expression of HOXA11, collagen type I, collagen type III, MMP2, and MMP9 in USLs of women with and without POP. Expression of HOXA11 and both collagens was dramatically decreased while MMP2 was increased in women with POP. Constitutive expression of Hoxa11 in murine fibroblasts resulted in significantly increased expression of collagen type III and decreased expression of MMP2. These results identified HOXA11 as an essential gene for the development of the USL and suggested that women with POP might have weakened connective tissue due to changes in a signaling pathway involving HOXA11, collagen type III, and MMP2.
