International Urogynecology Consultation Chapter 1 Committee 5: relationship of pelvic organ prolapse to associated pelvic floor dysfunction symptoms: lower urinary tract, bowel, sexual dysfunction and abdominopelvic pain

International Urogynecology Consultation Chapter 3 Committee 1 - Pessary Management

INTRODUCTION AND HYPOTHESIS

This manuscript is part of the International Urogynecological Consultation (IUC) on Pelvic Organ Prolapse (POP), Chapter 3, Committee 1 focusing on pessary management of POP.

METHODS

A narrative review was conducted by an international, multi-disciplinary group of clinicians working in the field of pelvic health following a search of the literature using the MeSH terms "pelvic organ prolapse" OR "urogenital prolapse" OR "vaginal prolapse" OR "uterovaginal prolapse" AND "pessary" OR "support device" OR "intravaginal device." Relevant studies, as determined after review using the Covidence manuscript review platform, were included.

RESULTS

A total of 540 articles were reviewed, of which 313 were included for this narrative review. The reported pessary fitting success rate ranges from 41% to 96.6%, and the continuation of successful use rate varied from 21% to 97.7%. The most likely predictors of unsuccessful fitting trials were previous POP surgery, previous hysterectomy, short vaginal length, wide genital hiatus, and posterior compartment involvement. Following successful pessary placement in individuals with POP, vaginal bulge and pressure resolved in over 90%. A significant improvement in obstructive voiding was reported in 40-97% of participants, urinary urgency in 38%, urgency urinary incontinence in 29-77%, and stress urinary incontinence in 9-45%. Older age and women who can self-manage the pessary care or had family support were factors associated with pessary continuation. Common reasons reported for discontinuation included expulsion, vaginal pain/discomfort, unwillingness to continue, erosions, desire for surgery, bleeding, symptoms not improved with pessary, and incontinence. More serious complications (fistula, bowel obstruction, pessary impaction, and vaginal cancer) are rare, and occur usually in older women in whom pessary maintenance has been neglected. There is no high-quality evidence to guide pessary choice. The current literature lacks studies specifically focused on determining the role of preventative measures, i.e., estrogen, pessary type/material as regards to pessary-associated complications (PACs). The review identified a lack of information about the relevant and required training and education (for healthcare professionals and patients) for pessary provision, use, and management.

CONCLUSIONS

There is a considerable body of published work on the use of pessaries for POP, including effectiveness, factors associated with success and failure, and complications. However, there is a dearth of published literature regarding how pessary types are selected by providers, how providers are trained, what defines competency in pessary provision, and what constitutes appropriate patient education related to pessary use and management.

Long-Term Outcomes (10 Years) of Sacrospinous Ligament Fixation for Pelvic Organ Prolapse Repair

Vaginal vault prolapse is one of the main reasons for reoperation in patients with pelvic organ prolapse. Effective correction of the vaginal apex is essential for lasting repair for these women. Apical suspension of the sacrospinous ligament is probably one of the main vaginal treatments still offered to patients today. We proposed an evaluation of the functional and anatomical results of long-term sacrospinous ligament fixation.

OBJECTIVE

The purpose of this study was to evaluate the 10-year results of sacrospinous ligament suspension as primary repair for apical prolapse and to evaluate long-term side effects.

MATERIALS AND METHODS

A retrospective study analyzed 10-year follow-up after prolapse repair using sacrospinous ligament suspension. A subjective recurrence was identified as the postoperative occurrence of swelling symptoms based on a particular item on the Italian Prolapse Quality of Life (P-QoL) questionnaire. An objective recurrence was defined as a postoperative decline to stage II or below in any compartment based on the POP-Q system or the requirement for additional surgery. The assessment of postoperative subjective satisfaction was conducted using the Patient Global Impression of Improvement (PGI-I) score.

RESULTS

In total, 40 patients underwent sacrospinous ligament fixation. Objective recurrence was remarkably high, as it was observed in 17 (56.7%) patients. Subjective recurrence was reported by ten (33.3%) women, and reintervention occurred in two (6.7%) of patients. From the point of view of quality of life, according to the PGI-I, twenty-three (76.7%) patients described some degree of improvement after surgery, four (13.3%) described their status as unmodified, and three (10%) reported some form of worsening after primary treatment.

CONCLUSIONS

Transvaginal repair with sacrospinous fixation is a long-lasting option for prolapse repair, with improvement in every POP-q parameter. Some degree of anterior recurrence, recurrence of symptoms with swelling, or an overall worsening of quality of life after surgery is possible.

De novo urinary incontinence and lower urinary tract symptoms after colpocleisis: A single-center prospective study

Background

Colpocleisis is one of traditional surgical procedures for elderly and frail women with advanced pelvic organ prolapse. The occurrence of de novo urinary incontinence following colpocleisis was considered to impair the postoperative quality of life. The incidence of de novo urinary incontinence after colpocleisis has been reported to be ranging from 6.6 % to 27 %. There was an absence of prospective large-sample study to investigate the accurate incidence of de novo urinary incontinence following colpocleisis and the impact on the quality of life till now.

Purpose

s The primary objective was to report the incidence of de novo urinary incontinence after colpocleisis. The second objectives were to evaluate the long-term quality of life in patients with de novo urinary incontinence, and to conduct detailed pre- and post-operative evaluations of lower urinary tract symptoms.

Methods

This prospective study included 253 patients with symptomatic pelvic organ prolapse who underwent colpocleisis between 2009 and 2021. De novo urinary incontinence was defined as the occurrence of urinary incontinence 3 months postoperatively. All patients were required to complete the Urinary Distress Inventory questionnaire and the Urinary Impact Questionnaire for the evaluation of patients' quality of life, and the Patient Global Impression of Improvement questionnaire for the evaluation of patients' satisfaction.

Results

245 patients (245/253, 96·8 %) completed the 3-month follow-up, and were included in the final analysis. The incidence of de novo urinary incontinence was 5.4 % (10/185). There was no significant difference in the Urinary Distress Inventory -6 scores (22.50 vs. 10.30, P = 0.276) or the subjective satisfaction rate (100 % vs. 98.9 %, P = 0.250) between the patients with or without de novo urinary incontinence at the long-term follow-up. The incidence of voiding difficulty was significantly reduced after colpocleisis (27.8 % vs. 0.0 %, P < 0.001). The patients' quality of life indicated by Urinary Distress Inventory-6 and Urinary Impact Questionnaire-7 scores were significantly improved postoperatively (26.27 vs. 13.39, and 19.13 vs. 6.05, P < 0.05).

Conclusion

The incidence of de novo urinary incontinence after colpocleisis was very low. Patients' quality of life, and low urinary tract symptoms were significantly improved after colpocleisis.

Measuring Pelvic Organ Prolapse: An Evolution

INTRODUCTION AND HYPOTHESIS

Advances in our understanding of pelvic organ prolapse (POP) have been made with the introduction of valid, reliable measures of anatomy and patient-reported outcome measures.

METHODS

This review provides an overview of the evolution of POP measurement and its implications for clinical practice and research.

RESULTS

Since the introduction of the Pelvic Organ Prolapse Quantification (POPQ), studies have demonstrated that some degree of loss of anatomic support is normal, with as many as 40% of normal women having stage 2 prolapse. Vaginal support is dynamic and can wax and wane but is largely stable over time. Vaginal bulge symptoms are the most reliable and specific symptom for POP and the hymen is an important threshold for symptom development. Most pelvic floor symptoms have only weak to moderate correlation with the anatomic severity of POP. Treatment success rates are highly variable depending upon criteria used and definitions of anatomic success commonly used are too strict and often not clinically relevant. There is substantial discordance between subjective and anatomic measures of success, and both are dynamic, fluctuating between success and failure for many patients without intervening treatment.

CONCLUSIONS

Pelvic organ prolapse is multidimensional, dynamic, and has a complex impact on patients. Patients' symptoms are more clinically relevant than anatomic support. Symptomatic cure, particularly the absence of vaginal bulge symptoms, is more clinically relevant than anatomic cure and composite outcomes can be misleading and overestimate failure rates. Future studies should compare treatments using continuous variables along multiple dimensions rather than using composite outcomes or dichotomizing patients into success or failure.

The Incidence of Pelvic and Low Back Pain in Patients with Pelvic Organ Prolapse

INTRODUCTION AND HYPOTHESIS

To define the prevalence and incidence of pelvic/low back pain in patients with pelvic organ prolapse (POP).

METHODS

Patients presenting for POP to three urogynecology centers in the US, UK, and Chile were enrolled in an IRB-approved cross-sectional study assessing pain, GU, GI and sexual function symptoms. For prevalence, symptoms were noted as present if the participant recorded the symptom and reported the degree of bother as "somewhat," "a moderate amount," or "a lot." For incidence, participants were queried if the symptom's onset concurred with the POP. We also queried if they perceived the symptom was worsened by their POP.

RESULTS

Two hundred five participants were recruited: 100 from the US, 46 from the UK, and 59 from Chile. One US participant was excluded due a missing examination. The prevalence of pelvic pain was 42%. Seventy-three percent of these participants reported the onset of pelvic pain coinciding with prolapse onset, and 81% endorsed worsening pelvic pain with POP. The prevalence of low back pain was 46%, with 30% reporting the onset coincided with the onset of POP and 44% responded that prolapse worsened their pain.

CONCLUSION

A higher proportion of participants than expected endorsed pelvic/low back pain. Among patients with pelvic pain, the majority experienced symptom onset with POP onset and a worsening of pain with POP. While roughly half of participants reported low back pain; a minority correlated this to their POP. These findings highlight a high incidence of pelvic pain, challenging the perception of POP as a painless condition.

The relationship between low back pain, pelvic tilt, and lumbar lordosis with urinary incontinence using the DIERS formetric 4D motion imaging system

INTRODUCTION AND HYPOTHESIS

Urinary incontinence (UI) is a common public health problem and postural changes may be crucial in women presenting with UI. This study was aimed at evaluating the relationship between low back pain (LBP), pelvic tilt (PT), and lumbar lordosis (LL) in women with and without UI using the DIERS formetric 4D motion imaging system. To date no study has to our knowledge compared postural changes and LBP in women with UI using the DIERS 4D formetric system.

METHODS

This was a case-control study. We included 33 women with UI and 33 without incontinence. The severity of urogenital symptoms was assessed by the IIQ-7 (Incontinence Impact Score) and UDI-6 (Urogenital Distress Inventory), and disability owing to LBP was evaluated using the Oswestry Disability Index (ODI). Posture and movement assessment, LL angle, thoracic kyphosis, and PT assessment were performed with the DIERS Formetric 4D motion imaging system.

RESULTS

The LL angle and pelvic torsion degree were higher in the incontinence group than in the control group (53.9 ± 9.5° vs 48.18 ± 8.3°; p = 0.012, 3.9 ± 4.1 vs 2.03 ± 1.8 mm; p = 0.018 respectively). The LBP visual analog scale value was also significantly higher in the incontinence group (5.09 ± 2.3 vs 1.7 ± 1.8 respectively, p < 0.0001). The LL angle showed a positive correlation with pelvic obliquity, (r = 0.321, p < 0.01) and fleche lombaire (r = 0.472, p < 0.01) and a negative correlation with lumbar range of motion measurements. Pelvic obliquity correlated positively with pelvic torsion (r = 0.649, p < 0.01), LBP (r = 0.369, p < 0.01), and fleche lombaire (r = 0.269, p < 0.01).

CONCLUSIONS

Women with UI were more likely to have lumbopelvic sagittal alignment changes and a higher visual analog scale for LBP. These findings show the need for assessment of lumbopelvic posture in women with UI.

Characterization of Pain Associated With Pelvic Organ Prolapse: Is Surgery the Answer?

IMPORTANCE

Data on the incidence of pelvic organ prolapse (POP)-related pain, risk factors for its development, and treatment effects of surgery remain sparse.

OBJECTIVES

The aims of the study were to evaluate the incidence and characteristics of POP-related pain in patients presenting with POP and assess the outcome of pain after surgery.

STUDY DESIGN

This was a retrospective study of patients presenting for initial evaluation of POP from May 2019 to May 2020. Using a standardized questionnaire, patients were asked "Do you have pain associated with your prolapse (not pressure or fullness)?" and to indicate pain severity and location(s). Patients who underwent surgery were asked postoperatively if their POP-related pain resolved. Patient and perioperative characteristics were obtained from the medical record and used to evaluate relationships between the presence and resolution of POP-related pain.

RESULTS

Of the 795 patients who met inclusion criteria, 106 (13.3%) reported POP-related pain. The mean age of all patients was 59.9 years, 38.1% had stage 3 or greater POP, and 52.1% were sexually active. Women with POP-related pain reported a median severity of 5 of 10. The most common pain locations were the vagina (46.6%), lower abdomen (27.4%), and back (9.6%). Fifty-seven women with pain (53.8%) underwent surgery, and 40 (70.2%) reported postoperative pain resolution. Of those who did not have resolution, pain improved or remained stable in severity. No patients reported worsening pain after surgery.

CONCLUSIONS

Pain is a symptom experienced by more than 1 in 8 women presenting with POP, with 70% reporting resolution of their pain postoperatively.

International urogynecological consultation chapter 4.1: definition of outcomes for pelvic organ prolapse surgery

INTRODUCTION AND HYPOTHESIS

This manuscript of Chapter 4 of the International Urogynecological Consultation (IUC) on Pelvic Organ Prolapse (POP) reviews the literature and makes recommendations on the definition of success in the surgical treatment of pelvic organ prolapse.

METHODS

An international group containing seven urogynecologists performed an exhaustive search of the literature using two PubMed searches and using PICO methodology. The first search was from 01/01/2012-06/12/2022. A second search from inception to 7/24/2022 was done to access older references. Publications were eliminated if not relevant to the clinical definition of surgical success for the treatment of POP. All abstracts were reviewed for inclusion and any disagreements were adjudicated by majority consensus of the writing group. The resulting list of articles were used to inform a comprehensive review and creation of the definition of success in the surgical treatment of POP.

OUTCOMES

The original search yielded 12,161 references of which 45 were used by the writing group. Ultimately, 68 references are included in the manuscript. For research purposes, surgical success should be primarily defined by the absence of bothersome patient bulge symptoms or retreatment for POP and a time frame of at least 12 months follow-up should be used. Secondary outcomes, including anatomic measures of POP and related pelvic floor symptoms, should not contribute to a definition of success or failure. For clinical practice, surgical success should primarily be defined as the absence of bothersome patient bulge symptoms. Surgeons may consider using PASS (patient acceptable symptom state) or patient goal attainment assessments, and patients should be followed for a minimum of at least one encounter at 6-12 weeks post-operatively. For surgeries involving mesh longer-term follow-up is recommended.

International Urogynecology consultation chapter 2 committee 3: the clinical evaluation of pelvic organ prolapse including investigations into associated morbidity/pelvic floor dysfunction

INTRODUCTION AND HYPOTHESIS

This manuscript from Chapter 2 of the International Urogynecology Consultation (IUC) on Pelvic Organ Prolapse (POP) reviews the literature involving the clinical evaluation of a patient with POP and associated bladder and bowel dysfunction.

METHODS

An international group of 11 clinicians performed a search of the literature using pre-specified search MESH terms in PubMed and Embase databases (January 2000 to August 2020). Publications were eliminated if not relevant to the clinical evaluation of patients or did not include clear definitions of POP. The titles and abstracts were reviewed using the Covidence database to determine whether they met the inclusion criteria. The manuscripts were reviewed for suitability using the Specialist Unit for Review Evidence checklists. The data from full-text manuscripts were extracted and then reviewed.

RESULTS

The search strategy found 11,242 abstracts, of which 220 articles were used to inform this narrative review. The main themes of this manuscript were the clinical examination, and the evaluation of comorbid conditions including the urinary tract (LUTS), gastrointestinal tract (GIT), pain, and sexual function. The physical examination of patients with pelvic organ prolapse (POP) should include a reproducible method of describing and quantifying the degree of POP and only the Pelvic Organ Quantification (POP-Q) system or the Simplified Pelvic Organ Prolapse Quantification (S-POP) system have enough reproducibility to be recommended. POP examination should be done with an empty bladder and patients can be supine but should be upright if the prolapse cannot be reproduced. No other parameters of the examination aid in describing and quantifying POP. Post-void residual urine volume >100 ml is commonly used to assess for voiding difficulty. Prolapse reduction can be used to predict the possibility of postoperative persistence of voiding difficulty. There is no benefit of urodynamic testing for assessment of detrusor overactivity as it does not change the management. In women with POP and stress urinary incontinence (SUI), the cough stress test should be performed with a bladder volume of at least 200 ml and with the prolapse reduced either with a speculum or by a pessary. The urodynamic assessment only changes management when SUI and voiding dysfunction co-exist. Demonstration of preoperative occult SUI has a positive predictive value for de novo SUI of 40% but most useful is its absence, which has a negative predictive value of 91%. The routine addition of radiographic or physiological testing of the GIT currently has no additional value for a physical examination. In subjects with GIT symptoms further radiological but not physiological testing appears to aid in diagnosing enteroceles, sigmoidoceles, and intussusception, but there are no data on how this affects outcomes. There were no articles in the search on the evaluation of the co-morbid conditions of pain or sexual dysfunction in women with POP.

CONCLUSIONS

The clinical pelvic examination remains the central tool for evaluation of POP and a system such as the POP-Q or S-POP should be used to describe and quantify. The value of investigation for urinary tract dysfunction was discussed and findings presented. The routine addition of GI radiographic or physiological testing is currently not recommended. There are no data on the role of the routine assessment of pain or sexual function, and this area needs more study. Imaging studies alone cannot replace clinical examination for the assessment of POP.

The effect of prolapse surgery on voiding function

INTRODUCTION AND HYPOTHESIS

Of women with symptomatic prolapse, 13-39% experience voiding dysfunction (VD). The aim of our observational cohort study was to determine the effect of prolapse surgery on voiding function.

METHODS

Retrospective analysis of 392 women who underwent surgery between May 2005 and August 2020. All had a standardized interview, POP-Q, uroflowmetry and 3D/4D transperineal ultrasound (TPUS) pre-and postoperatively. Primary outcome was change in VD symptoms. Secondary outcomes were changes in maximum urinary flow rate (MFR) centile and post-void residual urine (PVR). Explanatory measures were change in pelvic organ descent as seen on POP-Q and TPUS.

RESULTS

Of 392 women, 81 were excluded due to missing data, leaving 311. Mean age and BMI were 58 years and 30 kg/m2, respectively. Procedures performed included anterior repair (n = 187, 60.1%), posterior repair (n = 245, 78.8%), vaginal hysterectomy (n = 85, 27.3%), sacrospinous colpopexy (n = 170, 54.7%) and mid-urethral sling (MUS) (n = 192, 61.7%). Mean follow-up was 7 (1-61) months. Pre-operatively, 135 (43.3%) women reported symptoms of VD. Postoperatively, this decreased to 69 (22.2%) (p < 0.001), and of those, 32 (10.3%) reported de novo VD. The difference remained significant after excluding concomitant MUS surgery (n = 119, p < 0.001). Postoperatively, there was a significant decrease in mean PVR (n = 311, p < 0.001). After excluding concomitant MUS surgery, there was a significant increase in mean MFR centile (p = 0.046).

CONCLUSIONS

Prolapse repair significantly reduces symptoms of VD and improves PVR and flowmetry.

Segmental Rectum Resection for Deep Endometriosis and Excision Similarly Improve Sexual Function and Pain

Segmental rectum resections for indications other than endometriosis were reported to result in up to 40% sexual dysfunctions. We, therefore, evaluated sexual function after low bowel resection (n = 33) for deep endometriosis in comparison with conservative excision (n = 23). Sexual function was evaluated with the FSFI-19 (Female Sexuality Functioning Index) and EHP 30 (Endometriosis Health Profile). The pain was evaluated with visual analogue scales. Linear excision and bowel resections improved FSFI, EHP 30, and postoperative pain comparably. By univariate analysis, a decreased sexual function was strongly associated with pain both before (p < 0.0001) and after surgery (p = 0.0012), age (p = 0.05), and duration of surgery (p = 0.023). By multivariate analysis (proc logistic), the FSFI after surgery was predicted only by FSFI before or EHP after surgery. No differences were found between low bowel segmental resection and a more conservative excision. In conclusion, improving pain after surgery can explain the improvement in sexual function. A deleterious effect of a bowel resection on sexual function was not observed for endometriosis. Sexual function in women with endometriosis can be evaluated using a simplified questionnaire such as FSFI-6.

Pelvic Organ Prolapse Syndrome and Lower Urinary Tract Symptom Update: What's New?

(1) Background: This narrative review aimed to analyze the epidemiological, clinical, surgical, prognostic, and instrumental aspects of the link between pelvic organ prolapse (POP) and lower urinary tract symptoms (LUTS), collecting the most recent evidence from the scientific literature. (2) Methods: We matched the terms "pelvic organ prolapse" (POP) and "lower urinary tract symptoms" (LUTS) on the following databases: Pubmed, Embase, Scopus, Google scholar, and Cochrane. We excluded case reports, systematic reviews, articles published in a language other than English, and studies focusing only on a surgical technique. (3) Results: There is a link between POP and LUTS. Bladder outlet obstruction (BOO) would increase variation in bladder structure and function, which could lead to an overactive bladder (OAB). There is no connection between the POP stage and LUTS. Prolapse surgery could modify the symptoms of OAB with improvement or healing. Post-surgical predictive factors of non-improvement of OAB or de novo onset include high BMI, neurological pathologies, age > 65 years, and the severity of symptoms; predictors of emptying disorders are neurological pathologies, BOO, perineal dysfunctions, severity of pre-surgery symptoms, and severe anterior prolapse. Urodynamics should be performed on a specific subset of patients (i.e., stress urinary incontinence, correct surgery planning), (4) Conclusions: Correction of prolapse is the primary treatment for detrusor underactivity and for patients with both POP and OAB.

Straining to void at preoperative urodynamic study as a risk factor for prolapse recurrence after surgery

OBJECTIVES

Straining to void is the need to make a muscular effort in order to initiate, maintain or improve the urinary stream, through an increase in abdominal pressure. This pattern of bladder emptying is frequently observed in women with pelvic organ prolapse causing urinary obstruction, to overcome the increased resistance to urine flow. However, frequent increases in abdominal pressure are a risk factor for developing pelvic organ prolapse, and might play a role in its recurrence after surgery. The aim of this study was to investigate the role of straining identified at urodynamic study in prolapse recurrence after surgical repair.

STUDY DESIGN

This was a retrospective study on women submitted to prolapse repair by vaginal hysterectomy with modified McCall culdoplasty and anterior colporraphy. All patients underwent a preoperative urodynamic evaluation including a pressure-flow study performed after prolapse reduction by means of a vaginal pessary; straining was defined by a simultaneous and similar increase in intravesical and abdominal pressures of at least 10 cmH₂O over the baseline during bladder emptying, corresponding to intermittent peaks of urine flow. Patients were divided into two groups according to the presence or absence of straining, and they were compared for surgical results at 12 months and for the rate of anterior or central recurrence over time.

RESULTS

Women with straining (n = 16), compared to women with normal voiding (n = 43), showed a higher risk of anterior recurrence over time at Kaplan-Meier curves, for both stage II (p = 0.02) and stage III prolapse (p = 0.02). No difference was seen for central recurrence during the follow up period. POP-Q staging at 12 months was similar for the two groups, except for the location of the Aa point which was significantly better for women without straining (-1.6 ± 0.1 cm vs -0.8 ± 0.3 cm, p = 0.03).

CONCLUSIONS

Straining to void identified in preoperative urodynamic study seems to increase the risk of anterior recurrence after surgical repair of pelvic organ prolapse.

Construction of a focal adhesion signaling pathway-related ceRNA network in pelvic organ prolapse by transcriptome analysis

Objective: Pelvic organ prolapse (POP) affects a large proportion of adult women, but the pathogenesis of POP remains unclear. The increase in global population aging will impose a substantial medical burden. Herein, we aimed to explore the related RNAs regulating the occurrence of POP and provide potential therapeutic targets.

Method: Tissue biopsies were collected from the anterior vaginal wall of six women with POP and six matched subjects without POP. The profiles of mRNAs, circRNAs, lncRNAs, and miRNAs were obtained by whole transcriptome RNA sequencing.

Result: The findings revealed that 71 circRNAs, 76 known lncRNAs, 84 miRNAs, and 931 mRNAs were significantly altered (p < 0.05 and |log2FC| > 1). GO and KEGG enrichment analyses indicated that the differentially expressed genes (DEGs) were mainly enriched in the focal adhesion signaling pathway. FLT, ITGA9, VEGFD, PPP1R12B, and ROCK2 were identified as focal adhesion signaling pathway-related hub genes by protein–protein interaction network analysis. Based on the relationships between the DEGs and miRNA, lncRNA and circRNA targets, we constructed a focal adhesion signaling pathway-related ceRNA network. The ceRNA network includes hsa_circ_0002190/hsa_circ_0046843/lnc-CARMN -miR-23a-3p - ROCK2 and hsa_circ_0001326/hsa_circ_0007733/lnc-AC107959/lnc-TPM1-AS - miR-205-5p - ROCK2/PPP1R12B/VEGFD. Moreover, abnormalities in the cytoskeleton in fibroblasts from individuals with POP were observed.

Conclusion: In this study, a focal adhesion signaling pathway-related ceRNA network was constructed, and this network may serve as a target for finding suitable drugs for the treatment of POP.
