ABSTRACT

INTRODUCTION AND HYPOTHESIS: Pregnancy and childbirth predispose to pelvic floor dysfunction (PFD), coinciding with functional and anatomical changes in the pelvic floor. To some extent, these can be assessed by transperineal ultrasound (TPUS), yet the correlation between ultrasound findings and symptoms has not been well elucidated. We hypothesised that pregnant women with PFD would show different findings at TPUS. METHODS: This is a planned secondary analysis of a prospective cohort study. Pregnant women were asked to fill out standardised questionnaires on PFD and undergo TPUS at 12-14 weeks and 28-32 weeks of gestation. We compared bladder neck descent, urethral rotation, retrovesical angle, pelvic organ descent, genital hiatus dimensions and the presence of anal sphincter defects between women with and those without PFD using t test and Fisher's exact test. Linear mixed-effects models were used to assess the correlation between TPUS findings and PFD severity. As this is a secondary subgroup analysis of participants who underwent TPUS, no sample size was determined upfront. RESULTS: At Valsalva, women with urinary incontinence had more pronounced bladder neck descent (p = 0.02) and urethral rotation (p < 0.01), as well as wider retrovesical angles (p = 0.04) and larger genital hiatus areas (p < 0.01). After controlling for age, BMI and parity, the retrovesical angle was the only persistent predictor of urinary incontinence. No correlation was observed between any TPUS marker and symptoms of either prolapse or anorectal dysfunction. CONCLUSIONS: In pregnant women, symptoms of urinary incontinence, but not of prolapse and anorectal dysfunction, are associated with differences in pelvic floor anatomy at TPUS.

ABSTRACT

Complications following surgical repair of pelvic organ prolapse (POP) with polypropylene mesh (PPM) are common. Recent data attributes complications, in part, to stiffness mismatches between the vagina and PPM. We developed a 3D printed elastomeric membrane (EM) from a softer polymer, polycarbonate urethane (PCU). EMs were manufactured with more material given the low inherent material strength of PCU. We hypothesized that the EMs would be associated with an improved host response as compared to PPM. A secondary goal was to optimize the material distribution (fiber width and device thickness) within EMs, in regards to the host response. EM constructs (2×1cm2) with varied polymer stiffness, fiber width, and device thickness were implanted onto the vagina of New Zealand white rabbits for 12 weeks and compared to similarly sized PPMs. Sham implanted animals served as controls. Mixed effects generalized linear models were used to compare the effect of construct type accounting for differences in independent variables. EMs had an overall superior host response compared to PPM as evidenced by preservation of vaginal smooth muscle morphology (p-values<0.01), decreased total cellular response to construct fibers (p-values<0.001), and a reduced percent of macrophages (p-values<0.02) independent of how the material was distributed. Both PP and EMs negatively impacted vaginal contractility and glycosaminoglycan (GAG) content relative to Sham (all p-values<0.001) with EMs having less of an impact on GAGs (p-values<0.003). The results suggest that softer PCU EMs made with more material are well tolerated by the vagina and comprises a future material for POP repair devices. STATEMENT OF SIGNIFICANCE: Prolapse is a debilitating condition in which loss of support to the vagina causes it and the organs supported by it to descend from their normal position in the pelvis. Surgical solutions to rebuild support involves the use of polypropylene mesh which is orders of magnitude stiffer than the vagina. This mismatch results in complications including exposure of the mesh into the vagina and pain. To provide an innovative solution for women, we have developed an elastomeric membrane from a soft polymer that matches the stiffness of the vagina. Here, we show in a rabbit animal model that this device incorporates better into the vagina and is associated with an overall improved host response as compared to polypropylene mesh.

ABSTRACT

BACKGROUND: Patient-reported outcome measures (PROMs) are recommended to measure the impact of a health condition or intervention effectiveness as they aim to capture what is most meaningful to patients. Several PROMs are used to evaluate pelvic organ prolapse (POP)-related domains, yet the measurement properties of these instruments have not been fully explored with a rigorous analysis of the methodological quality and quality of evidence. OBJECTIVE: To conduct a systematic review reporting on the measurement properties of PROMs used for the assessment of POP-related domains in accordance with the COSMIN guidelines. SEARCH STRATEGY: Five databases were searched from inception to December 2023. SELECTION CRITERIA: Studies were eligible if they involved (1) at least one group of female adults diagnosed with or presenting with symptoms of POP; (2) a self-reported outcome measure (PROMs, questionnaires) to evaluate POP-related domains; and (3) at least one measurement property. DATA COLLECTION AND ANALYSIS: Methodological quality and measurement quality were assessed using the COSMIN risk of bias (ROB) checklist and the COSMIN criteria for good measurement properties. MAIN RESULTS: A total of 13 PROMs were included. The BIPOP had the lowest ROB for Content Validity. The POP-SS was the only PROM with sufficient evidence of adequate construct validity and responsiveness to be used in both surgical and conservative management settings. CONCLUSION: This original work identified a gap in evidence regarding the measurement qualities of identified PROMs used in the POP population.

ABSTRACT

INTRODUCTION AND HYPOTHESIS: Vaginal pessaries are the mainstay of the non-surgical management of pelvic organ prolapse (POP). A flexible silicone irregular hexagonal (SIH) pessary was developed based on the results of a prior vaginal case study. We hypothesised that the SIH pessary would have a higher rate of retention and self-management than the polyvinyl chloride (PVC) pessary. METHODS: This was a prospective non-blinded, randomised controlled trial with institutional review board approval. Eligible participants were randomised and fitted with the assigned pessary. They were reviewed 1 week, 6 months and 1 year after the initial pessary fitting. Participants who returned for follow-up completed the study questionnaires. The primary outcome was success, defined as continued use of the allocated pessary at 6 months. Secondary outcomes included the ability to perform pessary self-care, treatment satisfaction and pessary-related complications. Statistical tests were performed with alpha or statistical significance defined as a p value of ≤ 0.05, two-tailed. RESULTS: A total of 104 participants were randomised, with 52 subjects in each arm. Primary outcome data were analysed using per protocol analysis. Continuing pessary usage at 6 months was 68.1% for the PVC pessary group and 65.1% for the SIH group, with no statistically significant differences between the two groups (p = 0.765). Subjects with SIH were more likely to perform pessary self-care. There were no significant differences in subjects' satisfaction, quality-of-life scores or treatment complications between groups. CONCLUSIONS: The pessary continuation rate between the SIH and the PVC pessary groups was similar at 6 months. Participants with an SIH pessary were more likely to self-manage.

ABSTRACT

BACKGROUND: Pelvic organ prolapse (POP) is one of the most common pathologies of the pelvic floor, and it can be found among 40-60% of women who have given birth. Correction of the defect of the DeLancey level II without reconstruction of the apical defect is doomed to failure. Also, in the structure of pelvic floor defects, there is often an incompetency of the perineal body, as a consequence of traumatic delivery. Perineoplasty is considered to be the main method of correction for perineal body incompetency. However, it is worth mentioning that there are no randomized trials, which estimate the influence of simultaneous correction of the perineal body on the effectiveness of transvaginal apical fixation. METHODS: It is planned to include 310 patients in this trial. Patients who met the inclusion/exclusion criteria will be randomized into 2 groups: 1st group-patients who will undergo mesh-augmented sacrospinal fixation with anterior and posterior colporrhaphy without perineoplasty, 2nd group-patients who will undergo mesh-augmented sacrospinal fixation with anterior and posterior colporrhaphy and perineoplasty. Patients will be called to an appointment 6, 12, and 24 months after discharge. DISCUSSION: The aim of this trial is to evaluate the efficiency and safety of simultaneous perineoplasty on the clinical and anatomical efficacy of mesh-augmented sacrospinal fixation in advanced pelvic organ prolapse repair. Based on previous studies, it was difficult to estimate and comprehend whether colpoperinoplasty actually reduces the risk of prolapse recurrence. TRIAL REGISTRATION: NCT05422209.

ABSTRACT

INTRODUCTION: Surgeries for pelvic organ prolapse (POP) and stress urinary incontinence (SUI) are commonly performed in older adults, many of whom are also frail. A surgical risk calculator for older adults undergoing POP/SUI surgeries that incorporates frailty, a factor known to increase the risk of surgical complications, would be helpful for preoperative counseling but currently does not exist. MATERIALS AND METHODS: Medicare Carrier, Outpatient, and MedPAR files were examined for beneficiaries undergoing POP and SUI surgery between 2014 and 2016. A total of 15 POP/SUI categories were examined. The Claims-Based Frailty Index (CFI), a validated measure of frailty in Medicare data, and Charlson Comorbidity Index were deconstructed into their individual variables, and individual variables were entered into stepwise logistic regression models to determine which variables were most highly predictive of 30-day complications and 1-year mortality. To verify the prognostic accuracy for each model for surgical complications of interest, calibration curves and tests of model fit, including C-statistic, Brier scores, and Spiegelhalter p values, were determined. RESULTS: In total, 108 479 beneficiaries were included. Among these, 4.7% had CFI scores consistent with mild to severe frailty (CFI≥0.25). A total of 13 prognostic variable categories were found to be most highly predictive of postoperative complications. Calibration curves for each outcome of interest showed models were well-fit. Most models demonstrated high c-statistic values (≥0.7) and high Spiegelhalter p values (≥0.9), indicating good model calibration and excellent discrimination, and low Brier scores (<0.02), indicating high model accuracy. CONCLUSIONS: Urologic surgery for older Adults Risk Calculator serves as a novel surgical risk calculator that is readily accessible to both patients and clinicians that specifically factors in components of frailty. Furthermore, this calculator accounts for the heterogeneity of an aging population and can assist in individualized surgical decision-making for these common procedures.

ABSTRACT

BACKGROUND: Surgeries for treating pelvic organ prolapse involving the utilization of synthetic mesh have been associated with complications such as mesh erosion, postoperative pain, and dyspareunia. This work aimed to reduce the surgical implantation-associated complications by nanofibrous membranes on the surface of the polypropylene mesh. The nanofiber of the nanofibrous membrane, which was fabricated by co-axial electrospinning, was composed of polyurethane as fiber core and gelatin as the fiber out layer. The biocompatibility of the modified mesh was evaluated in vitro by cell proliferation assay, immunofluorescence stain, hematoxylin-eosin (HE) staining, and mRNA sequencing. Polypropylene mesh and modified mesh were implanted in a rat pelvic organ prolapse model. Mesh-associated complications were documented. HE and Picro-Sirius red staining, immunohistochemistry, and western blotting were conducted to assess the interactions between the modified mesh and vaginal tissues. RESULTS: The modified mesh significantly enhanced the proliferation of fibroblasts and exerted a positive regulatory effect on the extracellular matrix anabolism in vitro. When evaluated in vivo, no instances of mesh exposure were observed in the modified mesh group. The modified mesh maintained a relatively stable histological position without penetrating the muscle layer or breaching the epidermis. The collagen content in the vaginal wall of rats with modified mesh was significantly higher, and the collagen I/III ratio was lower, indicating better tissue elasticity. The expression of metalloproteinase was decreased while the expression levels of tissue inhibitor of metalloproteinase were increased in the modified mesh group, suggesting an inhibition of collagen catabolism. The expression of TGF-ß1 and the phosphorylation levels of Smad3, p38 and ERK1/2 were significantly increased in the modified mesh group. NM significantly improved the biocompatibility of PP mesh, as evidenced by a reduction in macrophage count, decreased expression levels of TNF-α, and an increase in microvascular density. CONCLUSIONS: The nanofibrous membrane-coated PP mesh effectively reduced the surgical implantation complications by inhibiting the catabolism of collagen in tissues and improving the biocampibility of PP mesh. The incorporation of co-axial fibers composed of polyurethane and gelatin with polypropylene mesh holds promise for the development of enhanced surgical materials for pelvic organ prolapse in clinical applications.

ABSTRACT

PURPOSE: Stress urinary incontinence is a postoperative complication occurring in patients with pelvic organ prolapse (POP). Although the 1-hour pad test measures the degree of urinary incontinence qualitatively and quantitatively, some elderly women undergoing POP surgery do not have the daily activities of living to perform the pad test. Therefore, we examined whether the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) could be used as an alternative tool for pad tests. METHODS: We retrospectively evaluated 132 patients with POP. In our hospital, 57 patients were treated by laparoscopic sacrocolpopexy (LSC), whereas 75 were treated by transvaginal mesh surgery (TVM). We measured the changes in symptoms preand postoperatively using the ICIQ-SF and 1-hour pad weight testing, and investigated the correlation between the total plus component question scores of the ICIQ-SF and 1-hour pad weight. RESULTS: The preoperative ICIQ total scores in all patients decreased significantly as the amount of leakage on the 1-hour pad weight decreased. The component question scores also decreased significantly with decreasing levels of 1-hour pad weight. The LSC and TVM groups had decreased ICIQ-SF total and component question scores as pad weight decreased. At 12 months postoperatively, the ICIQ total scores in all patients significantly declined as the amount of leakage on the 1-hour pad weight decreased. In the LSC group, the ICIQ-SF total and component question scores also decreased with decreased pad weight, but the differences were not always significant between ICIQ scores and pad weight. In the TVM group, the ICIQ-SF total and component question scores also significantly decreased as the pad weight decreased. CONCLUSION: The ICIQ-SF could be an appropriate substitute for the 1-hour pad weight testing in predicting the severity of urinary incontinence. In the future, we hope to predict the level of urine leakage based on the ICIQ-SF score.

ABSTRACT

PURPOSE: To describe the clinical presentation and urodynamic findings in detrusor underactivity (DU) patients and investigate the association between DU and straining related complications such as pelvic organ prolapse (POP), inguinal hernia, and hemorrhoids. METHODS: We retrospectively reviewed all consecutive patients who underwent urodynamic studies (UDS) from 2012 to 2023, divided into two groups: those with evidence of DU (n = 573), and control subjects with normal voiding parameters (n = 522). Exclusion criteria were patients who lacked sufficient data, those with obstructive voiding parameters, and those who had received intravesical botulinum toxin injections within the previous nine months. Demographic information, clinical presentation, straining related complications, and UDS findings were compared between the two groups using univariate statistical analysis. RESULTS: The male DU group had a statistically significant higher prevalence of spinal disease and previous cerebrovascular accidents, while the female DU group had a statistically significant higher prevalence of spinal disease, multiple sclerosis, diabetes, previous colorectal surgery, previous transabdominal gynecological surgery, POP surgery, and recurrent UTIs. Female DU patients had a higher prevalence of pronounced vaginal bulging symptoms, recurrent POP, inguinal hernia, and hemorrhoids. The predominant LUTS were voiding symptoms (81.2% in males and 77.9% in females), followed closely by storage symptoms (66.2% in males and 74.7% in females). The median Qmax, PdetQmax, and PVR were 6 ml/sec, 18 cmH2O, 190 ml for male DU patients, and 8 ml/sec, 11 cmH2O, and 200 ml for female DU patients, respectively. CONCLUSION: Risk factors for DU that were identified include age, neurological diseases (spinal disease, CVA in men, MS in women), diabetes and transabdominal surgery (colorectal, gynecological) that can cause pelvic denervation in women. DU patients commonly present with both voiding and storage symptoms. There is approximately twice the risk of having POP surgery and inguinal hernia, an eight-fold risk of hemorrhoids, and a three-fold risk of recurrent UTIs for females. This is thought to be secondary to increased intra-abdominal pressure during urinary straining.

ABSTRACT

This study aimed to explore the association between genetic polymorphisms in the chromosome region 9q21 and the risk of pelvic organ prolapse (POP) in Northwestern Chinese women. A case-control study was conducted with 241 POP patients and 268 healthy controls, analyzing ten single nucleotide polymorphisms (SNPs) across five genes using PCR amplification and Sequenom MassArray. The results revealed significant associations between three SNPs-rs2297002 in GOLM1, rs7450 in MAK10, and rs3814535 in TLE1-and POP. Specifically, the TC genotype of rs2297002, the GA genotype of rs7450, and the AA genotype of rs3814535 were linked to an increased or decreased risk of POP. The study suggests that these genetic variants might contribute to the pathogenesis of POP in this population, offering potential markers for early diagnosis and further investigation into the molecular mechanisms underlying POP.


Cette étude visait à explorer l'association entre les polymorphismes génétiques dans la région chromosomique 9q21 et le risque de prolapsus des organes pelviens (POP) chez les femmes chinoises du nord-ouest. Une étude cas-témoins a été menée auprès de 241 patientes atteintes de POP et de 268 témoins sains, analysant dix polymorphismes nucléotidiques simples (SNP) sur cinq gènes à l'aide de l'amplification par PCR et du Sequenom MassArray. Les résultats ont révélé des associations significatives entre trois SNP (rs2297002 dans GOLM1, rs7450 dans MAK10 et rs3814535 dans TLE1) et le POP. Plus précisément, le génotype TC de rs2297002, le génotype GA de rs7450 et le génotype AA de rs3814535 étaient liés à un risque accru ou réduit de POP. L'étude suggère que ces variantes génétiques pourraient contribuer à la pathogenèse du POP dans cette population, offrant des marqueurs potentiels pour un diagnostic précoce et une étude plus approfondie des mécanismes moléculaires sous-jacents au POP.

ABSTRACT

BACKGROUND: Although the uterus, bladder, and rectum are distinct organs, their muscular fasciae are often interconnected. Clinical experience suggests that they may share common risk factors and associations. When one organ experiences prolapse, it can potentially affect the neighboring organs. However, the current assessment of disease severity still relies on manual measurements, which can yield varying results depending on the physician, thereby leading to diagnostic inaccuracies. PURPOSE: This study aims to develop a multilabel grading model based on deep learning to classify the degree of prolapse of three organs in the female pelvis using stress magnetic resonance imaging (MRI) and provide interpretable result analysis. METHODS: We utilized sagittal MRI sequences taken at rest and during maximum Valsalva maneuver from 662 subjects. The training set included 464 subjects, the validation set included 98 subjects, and the test set included 100 subjects (training set n = 464, validation set n = 98, test set n = 100). We designed a feature extraction module specifically for pelvic floor MRI using the vision transformer architecture and employed label masking training strategy and pre-training methods to enhance model convergence. The grading results were evaluated using Precision, Kappa, Recall, and Area Under the Curve (AUC). To validate the effectiveness of the model, the designed model was compared with classic grading methods. Finally, we provided interpretability charts illustrating the model's operational principles on the grading task. RESULTS: In terms of POP grading detection, the model achieved an average Precision, Kappa coefficient, Recall, and AUC of 0.86, 0.77, 0.76, and 0.86, respectively. Compared to existing studies, our model achieved the highest performance metrics. The average time taken to diagnose a patient was 0.38 s. CONCLUSIONS: The proposed model achieved detection accuracy that is comparable to or even exceeds that of physicians, demonstrating the effectiveness of the vision transformer architecture and label masking training strategy for assisting in the grading of POP under static and maximum Valsalva conditions. This offers a promising option for computer-aided diagnosis and treatment planning of POP.

ABSTRACT

Background: Minimally invasive surgery could improve cosmetic outcomes and reduce the risks of surgical injury with less postoperative pain and a quicker patient's discharge. Recently, transvaginal natural orifice transluminal endoscopic surgery (vNOTES) has been introduced in urogynecology with exciting results. Evidence Acquisition: After PROSPERO registration (n°CRD42023406815), we performed a comprehensive literature search on Pubmed, Embase, and Cochrane CENTRAL, including peer-reviewed studies evaluating transvaginal natural orifice transluminal endoscopic surgery. No limits on time or type of study were applied. Evidence synthesis: Overall, 12 manuscripts were included in the analysis. Seven studies evaluated uterosacral ligament suspension, four studies evaluated sacral colpopexy, three evaluated sacrospinous ligament suspension, and one study evaluated lateral suspension. Overall success rates were high (>90%); however, definitions of success were heterogeneous. In terms of complication, most of the studies reported low-grade complications (Clavien-Dindo I and II); only two patients needed mesh removal because of mesh exposure. The risk of bias of the trials was rated in the medium to high-risk category. Conclusions: The present review highlights important initial results for vNOTES. Future randomized clinical trials are needed to better define its role in the management of urogynecological procedures.

ABSTRACT

INTRODUCTION AND HYPOTHESIS: Changes in the expression of type III collagen have been linked to women's predisposition to pelvic organ prolapse (POP); however, the findings of prior studies have been conflicting. This study was aimed at investigating whether changes in the type III collagen gene expression levels occur in POP development. METHODS: A systematic review and meta-analysis were conducted on research articles that evaluated type III collagen gene expression levels in patients with POP compared with those without the condition. The articles, published between January 2000 and February 2024, were obtained from PubMed, ScienceDirect, Semantic Scholar, and EBSCO databases. Data were analyzed using fixed-effect models, and the pooled standardized mean difference (SMD) was calculated. Cochrane's Review Manager 5.4 was used for the analysis. The aggregated SMD with 95% confidence interval (CI) regarding type III collagen gene expression levels relative to POP development was the main outcome measure. Results with p < 0.05 were considered statistically significant. RESULTS: Six studies were included in our analysis, comprising 229 POP cases and 139 non-POP cases. Our meta-analysis indicated that patients with POP had higher type III collagen gene expression levels than those without POP (SMD = 0.32; 95% CI: 0.07 to 0.56; p = 0.01). CONCLUSION: The results of this study provide evidence that a higher type III collagen gene expression levels is significantly associated with POP.

ABSTRACT

OBJECTIVE: Senolytic agents have the potential to target age-related pathology associated with cellular senescence and reduce senescent cell activity in several disease processes. We utilized a mouse model of pelvic organ prolapse, Fibulin-5 knockout (Fbln-5-/-) mice, to assess the ability of dasatinib and quercetin (D+Q) to prevent development of prolapse. METHODS: Four-week-old female Fbln-5-/- (n=63) and wild-type (WT) mice (n=54) were assigned to control (vehicle injection) or treatment (D = 5 mg/kg, Q = 50 mg/kg) groups. Weekly oral gavage injections were administered from weeks 4-8 of life. Pelvic organ prolapse quantification system measurements were obtained weekly. Vaginal tissue was harvested at 10, 12 and 20 weeks. Tissue analysis included immunostaining for cell cycle inhibitors, multiplex cytokine analysis, senescence-associated-ß-galactosidase (SA-ß-Gal) and histologic analysis of extracellular matrix proteins. RESULTS: Perineal body length was significantly longer in Fbln-5-/- treatment mice at 20 weeks. Expression of p16 and p53 was decreased in Fbln-5-/- treatment mice compared to controls (4.0% vs. 26.7%, p=0.0124 and 2.9% vs. 16.8%, p=0.272) at 20 weeks. Expression of SA-ß-Gal and senescence-associated cytokines did not vary significantly between groups. At 20 weeks, vaginal tissue elastin content in Fbln-5-/- treatment mice increased compared to controls (1.04% vs. 0.84%, p=0.999). CONCLUSIONS: D+Q injections did not result in clinically significant differences in prolapse development but did demonstrate decreased expression of cellular senescence markers in Fbln-5-/- mice. This suggests senolytic agents may mitigate contributions of cellular senescence to tissue dysfunction associated with prolapse. Further studies are needed to confirm ideal timing, dosage, and route of senolytics in prevention of prolapse.

ABSTRACT

The objective benefit of transvaginal mesh with concomitant total hysterectomy (TVM-HTX) repair to high-grade uterine prolapse (UP) patients has not been fully established. This study aimed to clarify the impact of TVM-HTX on the voiding function of high-grade UP patients by comparing pre- and post-operatively measured pressure-flow and pressure-volume investigations. Urodynamic and thermodynamic studies were conducted on 15 high-grade UP patients (stage III/IV, POP-Q system) who underwent TVM-HTX (January 2019-December 2022) in a tertiary-care university hospital. The parameters analyzed included voiding resistance (Rvod), voiding pressure (Pvod), voiding flow (Fvod), voided volume (Vvod), voiding time (Tvod), and the trajectory-enclosed area of the pressure-volume loop (Apv). Post-operative results showed a significant reduction in Rvod (p < 0.001, N = 15), Pvod (p = 0.021, N = 15), and Apv (p = 0.006, N = 15), along with an increase in Fvod (p = 0.003, N = 15) and a decrease in Tvod (p < 0.001, N = 15). The operation-associated changes in Rvod (ΔRvod) correlated with alterations in Pvod and Fvod (ΔPvod and ΔFvod, r = 0.444, p = 0.004, r = 0.717, p = 0.003, respectively; both N = 15); ΔFvod correlated with the change in Tvod (ΔTvod, r = 0.629, p = 0.012, N = 15) but not with that in ΔVvod (r = 0.166, p = 0.555, N = 15). Changes in Apv (ΔApv) correlated with ΔPvod (r = 0.563, p = 0.029, N = 15) but not with ΔVvod (r = 0.353, p = 0.197, N = 15). Collectively, TVM-HTX reduced the voiding resistance, which improved the voiding efficacy and decreased the pressure gradient required for driving urine flow, thereby lessening the bladder's workload.

ABSTRACT

Pelvic organ prolapse (POP) is a benign disease characterized by the descent of pelvic organs due to weakened pelvic floor muscles and fascial tissues. Primarily affecting elderly women, POP can lead to various urinary and gastrointestinal tract symptoms, significantly impacting their quality of life. The pathogenesis of POP predominantly involves nerve-muscle damage and disorders in the extracellular matrix metabolism within the pelvic floor. Recent studies have indicated that genetic factors may play a crucial role in this condition. Focusing on linkage analyses, single-nucleotide polymorphisms, genome-wide association studies, and whole exome sequencing studies, this review consolidates current research on the genetic predisposition to POP. Advances in epigenetics are also summarized and highlighted, aiming to provide theoretical recommendations for risk assessments, diagnoses, and the personalized treatment for patients with POP.

ABSTRACT

Background: The Minimally Invasive Prolapse System (MIPS) device, a novel single-incision transvaginal mesh, represents recent advancements in mesh technology, providing lightweight, biocompatible support for pelvic organ prolapse while reducing erosion, allowing for customization and improving surgical outcomes. This study aimed to identify factors associated with pelvic organ prolapse (POP) recurrence after transvaginal mesh (TVM) repair using the Minimally Invasive Prolapse System device. Methods: Two hundred and eighteen women with symptomatic stage II to IV POP underwent TVM. Preoperative and postoperative assessments included urinalyses and pelvic examinations using the POP quantification (POP-Q) staging system. Results: During a follow-up period of 12-46 months, 7 of 218 (3.2%) women experienced POP recurrence. Univariate analysis was conducted to identify predictors of surgical failure, revealing no significant differences in body mass index, POP stage, or preoperative urinary symptoms between the recurrence and success groups (p > 0.05). However, functional urethral length <20 mm based on urodynamics (p = 0.011), ICI-Q scores ≥7 (p = 0.012), and the first 60 surgical cases (p = 0.018) were significant predictors of surgical failure. Multivariate logistic regression confirmed these findings. Conclusions: Functional urethral length <20 mm, ICI-Q scores ≥7, and limited surgical experience were significant predictors of TVM failure using the Minimally Invasive Prolapse System kit. POP recurrence after mesh repair is less likely beyond the learning curve.

ABSTRACT

Background: This study aimed to evaluate the safety and efficacy of minimally invasive sacrospinous ligament (SSL) fixation of apical pelvic organ prolapse (POP) in older patients compared to younger patients. Methods: A cohort of 271 older (≥65 years) patients (mean age 71.8 ± 5.2 years) and 60 younger patients (mean age 47.6 ± 7.1 years) with stage III or IV apical POP who underwent SSL fixation by the EnPlace® device was retrospectively analyzed. The age range of older patients was further divided into early old (65-74 y, N = 209), old (75-84 y, N = 58), and late old (>85 y, N = 4). Patient characteristics, surgical safety, and 6-month postoperative outcomes were compared between the four age groups. Results: Duration of surgery and blood loss were similar among all age groups. Most patients (99.4%) were discharged on the day of surgery or the day after. Subjective patient satisfaction rates were high among all patients. Point C measurements at six months postoperatively were less favorable among the younger patients. Furthermore, four (6.7%) younger patients versus six (2.2%) older patients required surgical repair of recurrent apical POP within the follow-up period. Conclusions: The short-term outcomes of minimally invasive SSL fixation suggest that it is a safe and effective procedure for significant apical POP repair among older patients.

ABSTRACT

OBJECTIVES: This prospective comparative cohort study aims to evaluate the safety and efficacy of transvaginal mesh compared to native tissue repair (NTR) in the surgical correction of anterior and apical compartment pelvic organ prolapse (POP) over a 36-month follow-up period. METHODS: Prospective comparative cohort study to prove superiority for efficacy and non-inferiority for serious adverse events (SAEs). The setting was 49 sites across the United States, Canada, Europe, and Australia. Women with bothersome POP symptoms indicated for vaginal surgery with pelvic organ prolapse quantification (POP-Q) scores of Ba ≥0 and C ≥ -1/2 total vaginal length were included. Interventions included vaginal NTR or single-incision transvaginal mesh based on shared decision-making. POP recurrence, the primary efficacy endpoint, was defined as anatomical prolapse beyond the hymenal ring, subjective perception of protrusion or bulge, or retreatment in the target compartment. The primary safety endpoint consisted of the proportion of device and/or procedure-related SAEs in the target compartment. Secondary endpoints included surgical parameters, quality of life, postoperative pain, and sexual function. RESULTS: POP recurrence rate at 12 months was 13.1% in the Mesh-arm and 11.5% in the NTR-arm (P = 0.44). The primary safety endpoint was met, with the Mesh-arm demonstrating statistically non-inferior outcomes compared to the NTR-arm in the incidence of device and/or procedure-related SAEs in the target compartment through 12 months (P < 0.01). At 36 months, the surgical POP recurrence rate was 26.7% in the Mesh-arm and 27.0% in the NTR-arm. CONCLUSIONS: At 12- and 36-month follow-up, transvaginal mesh was not superior, but non-inferior in terms of efficacy and safety when compared to NTR for patients with combined anterior and apical compartment prolapse.

ABSTRACT

PURPOSE: Women with symptomatic pelvic organ prolapse are facing the choice between several treatment options and a potentially difficult decision. The aim of this study was to examine the effect of decisional conflict, patient characteristics and other decision-related factors on treatment decision in women with pelvic organ prolapse. METHODS: Data from the SHADE-POP trial were used. Women with symptomatic pelvic organ prolapse who visited their gynaecologist for (new) treatment options were included. In all participants, demographical characteristics and validated questionnaires concerning decisional conflict (DCS), shared decision making (SDM-Q-9), information provision (SCIP-B), anxiety and depression (HADS) and satisfaction with care (PSQ-18) were collected 2 weeks after the visit. Analyses were performed using univariate and multivariate linear and logistic regression analyses. RESULTS: Ninety six women with pelvic organ prolapse facing a treatment decision were included. An increase in decisional conflict as experienced by patients was related to the choice of more conservative treatment, such as pelvic floor muscle training or pessary, instead of surgery (p = 0.02). Shared decision making, better information provision and satisfaction with care were related to lower levels of decisional conflict (p = 0.001). CONCLUSION: Decisional conflict in women with pelvic organ prolapse favours conservative treatment instead of surgery. Gaining knowledge on the effect of decisional conflict, patient characteristics and other decision-related factors on treatment decision in pelvic organ prolapse will be a step towards a better-guided treatment decision and better patient-reported outcomes for this group of patients.
