Risk factors for prolapse recurrence: systematic review and meta-analysis

Coronal Plane Assessment for Levator Trauma

OBJECTIVE

Levator avulsion is a major etiological factor of pelvic organ prolapse (POP) and is primarily diagnosed on tomographic axial plane imaging. Two-dimensional imaging can also image the levator. The objective was to test reproducibility and validity of coronal plane assessment for diagnosis of levator trauma by assessing the coronal plane obtained on tomographic ultrasound imaging.

METHODS

A retrospective study of women who had undergone an interview, POPQ and four-dimensional translabial ultrasound at a tertiary urogynecological unit. Post-processing of archived volume data was performed for assessment; and levator muscle area and estimate of remnant muscle mass in the coronal plane. Interobserver reproducibility of the latter two measures and associations between various measures of levator trauma and POP were tested.

RESULTS

Interobserver agreement was good for percentage estimates (ICC 0.743), but fair for area measurements (ICC 0.482). Six hundred and twenty four women were seen, 468 (75%) had significant clinical prolapse. Full levator avulsions were diagnosed in 137 (22%). Mean TTS was 2.7 (range 0-12). On coronal plane assessment average muscle area was 1.47 (SD 0.76) cm2 and 1.55 (SD 0.74) cm2 on the right and left, respectively (P = .005). It was 76% and 79% for average estimates of muscle mass (P = .021). Both measures were strongly associated with POP; however, they were not superior to TTS in predicting POP.

CONCLUSION

Coronal plane assessment in volume data is reproducible and valid for evaluation of levator trauma. Muscle mass estimate may be a better measure than muscle area.

Apical Suspension Repair for Vaginal Vault Prolapse: A Randomized Clinical Trial

Importance

The optimal surgical repair of vaginal vault prolapse after hysterectomy remains undetermined.

Objective

To compare the efficacy and safety of 3 surgical approaches for vaginal vault prolapse after hysterectomy.

Design, Setting, and Participants

This was a multisite, 3-arm, superiority and noninferiority randomized clinical trial. Outcomes were assessed biannually up to 60 months, until the last participant reached 36 months of follow-up. Settings included 9 clinical sites in the US National Institute of Child Health and Human Development (NICHD) Pelvic Floor Disorders Network. Between February 2016 and April 2019, women with symptomatic vaginal vault prolapse after hysterectomy who desired surgical correction were randomized. Data were analyzed from November 2022 to January 2023.

Interventions

Mesh-augmented (either abdominally [sacrocolpopexy] or through a vaginal incision [transvaginal mesh]) vs transvaginal native tissue repair.

Main Outcomes and Measures

The primary outcome was time until composite treatment failure (including retreatment for prolapse, prolapse beyond the hymen, or prolapse symptoms) evaluated with survival models. Secondary outcomes included patient-reported symptom-specific results, objective measures, and adverse events.

Results

Of 376 randomized participants (mean [SD] age, 66.1 [8.7] years), 360 (96%) had surgery, and 296 (82%) completed follow-up. Adjusted 36-month failure incidence was 28% (95% CI, 20%-37%) for sacrocolpopexy, 29% (95% CI, 21%-38%) for transvaginal mesh, and 43% (95% CI, 35%-53%) for native tissue repair. Sacrocolpopexy was found to be superior to native tissue repair (adjusted hazard ratio [aHR], 0.57; 99% CI, 0.33-0.98; P = .01). Transvaginal mesh was not statistically superior to native tissue after adjustment for multiple comparisons (aHR, 0.60; 99% CI, 0.34-1.03; P = .02) but was noninferior to sacrocolpopexy (aHR, 1.05; 97% CI, 0-1.65; P = .01). All 3 surgeries resulted in sustained benefits in subjective outcomes. Mesh exposure rates were low (4 of 120 [3%] for sacrocolpopexy and 6 of 115 [5%] for transvaginal mesh) as were the rates of dyspareunia.

Conclusions and Relevance

Among participants undergoing apical repair for vaginal vault prolapse, sacrocolpopexy and transvaginal mesh resulted in similar composite failure rates at study completion; both had lower failure rates than native tissue repair, although only sacrocolpopexy met a statistically significant difference. Low rates of mesh complications and adverse events corroborated the overall safety of each approach.

Levator ani muscle avulsion and subsequent vaginal delivery: 8-year longitudinal follow-up

OBJECTIVES

To assess the evolution of levator ani muscle (LAM) avulsion from 1 year to 8 years after first delivery in women with and those without subsequent vaginal delivery. In addition, to assess whether women with full or partial avulsion 8 years after first delivery have larger LAM hiatal area and more symptoms of pelvic organ prolapse compared to women with normal LAM insertion.

METHODS

In this single-center longitudinal study, 195 women who were primiparous at the start of the study were included and underwent transperineal ultrasound examination 1 year and 8 years after first delivery. Muscle insertion was assessed by tomographic ultrasound imaging in the axial plane. Full LAM avulsion was defined as abnormal muscle insertion in all three central slices. Partial LAM avulsion was defined as abnormal muscle insertion in one or two central slices. Eight years after the first delivery, LAM hiatal area was assessed at rest, during maximum pelvic floor muscle contraction and on maximum Valsalva maneuver. To assess symptoms of pelvic organ prolapse, the vaginal symptoms module of the International Consultation on Incontinence Questionnaire was used.

RESULTS

At 1-year follow-up, 25 (12.8%) women showed signs of LAM avulsion, of whom 20 fulfilled the sonographic criteria of full avulsion and five of partial avulsion. Eight years after the first delivery, 35 (17.9%) women were diagnosed with avulsion, of whom 25 were diagnosed with full avulsion and 10 with partial avulsion. No woman with partial or full avulsion at 1 year had improved avulsion status at 8-year follow-up. Of the 150 women who had subsequent vaginal delivery, 21 (14.0%) women were diagnosed with partial or full LAM avulsion 1 year after first delivery, and 31 (20.7%) women were diagnosed with partial or full avulsion 8 years after first delivery. Of the 45 women without subsequent vaginal delivery, one woman with partial avulsion 1 year after first delivery was diagnosed with full avulsion at 8-year follow-up. All women with full avulsion at 1-year follow-up were diagnosed with full avulsion at 8-year follow-up regardless of whether they had subsequent vaginal delivery. At 8-year follow-up, women with full avulsion had statistically significantly larger LAM hiatal area compared to women with normal muscle insertion. Mean ± SD vaginal symptom scores ranged between 5.5 ± 5.7 and 6.0 ± 4.0 and vaginal symptom quality of life scores ranged between 0.9 ± 1.4 and 1.5 ± 2.2 and did not differ significantly between women with normal muscle insertion and women with partial or full avulsion at 8-year follow-up.

CONCLUSIONS

More LAM avulsions were present 8 years compared with 1 year after first delivery in women with subsequent vaginal delivery. Except for one primipara, all women without subsequent vaginal delivery had unchanged LAM avulsion status between 1 year and 8 years after their first delivery. Larger LAM hiatal area was found in women with full avulsion compared to those with normal muscle insertion at 8-year follow-up. Vaginal symptoms scores were low and did not differ between women with normal muscle insertion and those with partial or full avulsion at 8-year follow-up. © 2024 The Authors.

Risk Factors for Pelvic Organ Prolapse: Wide-Angled Mendelian Randomization Analysis

INTRODUCTION AND HYPOTHESIS

We hypothesized that some metabolic factors, lifestyle factors, and socioeconomic factors may have a causal effect on pelvic organ prolapse (POP).

METHODS

We selected instruments from corresponding genome-wide association studies (GWAS), which identified independent single nucleotide polymorphisms strongly associated with 12 potential risk factors. Summary statistics for POP were derived from two GWAS datasets, serving for discovery and replication stage. The primary analysis involved the use of the inverse-variance weighting mendelian randomization (MR) method, with additional sensitivity MR analyses conducted.

RESULTS

The univariable mendelian randomization (UVMR) analysis in both the discovery and replication stage provided evidence for significant causal effects between higher waist-to-hip ratio adjusted for body mass index (WHRadjBMI) levels, lower high-density lipoprotein cholesterol (HDL-C) levels, and lower educational attainment and higher POP risk, as well as a suggestive positive causal effect between triglycerides and POP. The multivariable mendelian randomization (MVMR) analysis showed that only HDL-C among the three blood lipid fractions could reduce the risk of POP. Mediation analysis indicated that HDL-C may partially mediate the effect of WHRadjBMI on POP risk, and the causal effect between educational attainment and POP may be mediated through WHRadjBMI and HDL-C.

CONCLUSIONS

Our study's evidence supported a causal relationship between WHRadjBMI, triglycerides, HDL-C, educational attainment, and POP risk. This highlights that clinicians may guide the general female population to control obesity and blood lipid levels to reduce the risk of POP.

Laparoscopic Versus Vaginal Uterosacral Ligament Suspension in Women With Pelvic Organ Prolapse: A Systematic Review and Meta-Analysis of the Literature

OBJECTIVE

Uterosacral ligament suspension (USLS) is one of the most frequently used operations for the restoration of apical support in women with uterovaginal prolapse. However, existing studies are inconclusive as to whether and which surgical access route is superior. The aim of the present meta-analysis is tentatively to compare the efficiency and the postoperative complications of laparoscopic USLS (L-USLS) and vaginal USLS (V-USLS), highlighting that current evidence remains inconclusive regarding the superiority of either surgical access route.

DATA SOURCES

We performed a systematic literature review of 5 major databases (Medline, Scopus, Google Scholar Cochrane Central Register of Controlled Trials and Clinicaltrials.gov) from inception till April 2023.

METHODS OF STUDY SELECTION

No language restrictions were applied. All comparative studies that compared L-USLS and V-USLS for the management of women with uterovaginal prolapse were included.

TABULATION, INTEGRATION, AND RESULTS

Data from 6 retrospective cohort studies on 856 patients were extracted and analyzed. The methodological quality of the included studies was assessed using the risk of bias in nonrandomized studies of interventions tool and ranged between moderate to serious. The pooled results suggest that L-USLS was associated with a potentially decreased incidence of ureteral compromise (odds ratio [OR], 0.19; 95% confidence interval [CI] 0.04-0.89; p = .04) and seemingly lower objective (OR 0.47; 95% CI 0.23-0.97; p = .04) and subjective recurrence rates (OR 0.46; 95% CI 0.23-0.92; p = .03). There were no significant differences between the rates of postoperative pain from USLS sutures, postoperative pelvic hematomas, the suture exposure/granulation tissue formation, and the prolapse recurrence retreatment among the 2 groups.

CONCLUSION

The present meta-analysis indicates that L-USLS is possibly associated with significantly fewer ureteral compromise rates and decreased subjective and objective recurrences rates compared to V-USLS. Nevertheless, given the limitations in data quality and heterogeneity of the included studies, these findings should be interpreted with caution. Large-scale randomized studies are essential to more definitively determine the relative merits of the laparoscopic versus vaginal approach.

The rs2018736 fibulin-5 polymorphism as a determinant for pelvic organ prolapse: a case-control study

OBJECTIVE

Fibulin-5 is a connective tissue component and may play a role in pelvic organ prolapse (POP) pathogenesis. This study aimed to verify the association of the rs2018736 polymorphism of the fibulin-5 gene with POP in postmenopausal Brazilian women, and to determine the risk factors for POP.

METHOD

This observational, cross-sectional, case-control study assessed postmenopausal women with advanced POP (stages III and IV) and control women (stages 0 and I) by examination and peripheral blood sample collection. DNA sequences were analyzed by real-time reverse-transcriptase polymerase chain reaction. A logistic regression model was used with p < 0.05 for significance.

RESULTS

A total of 565 participants were evaluated (325 POP and 240 control). The homozygous C allele of rs2018736 (CC) was protective against POP (odds ratio [OR] 0.49, 95% confidence interval [CI] 0.26-0.91). Age (OR 1.09, 95% CI 1.05-1.13), number of pregnancies (OR 1.14, 95% CI 1.01-1.28), vaginal delivery (OR 5.32, 95% CI 2.58-11.01), forceps delivery (OR 3.34, 95% CI 1.72-6.47), weight of newborn (OR 1.0007, 95% CI 1.0002-1.0011), family history of POP (OR 2.35, 95% CI 1.24-4.44), hypertension (OR 1.74, 95% CI 1.01-3.00) and diabetes (OR 2.19, 95% CI 1.07-4.48)] were independent predictors for POP; cesarean (OR 0.02, 95% CI 0.005-0.09) was protective.

CONCLUSION

The rs2018736-CC genotype of the fibulin-5 gene has a protective role against POP.

Levator Ani Avulsion in Ultrasound Increases Recurrence in Sacrospinous Fixation

IMPORTANCE

Pelvic floor translabial ultrasound (TLUS) can identify levator ani muscle (LAM) avulsion and ballooning, which some studies have shown to be possible risk factors for prolapse recurrence. Our group uses TLUS to counsel patients preoperatively. If any of these risk factors exist, we offer sacrocolpopexy over vaginal repair. However, some patients, even though they have these possible risk factors, prefer to undergo vaginal surgery.

OBJECTIVE

The objective of this study was to determine if TLUS LAM avulsion and/or ballooning are risk factors for composite outcome recurrence in patients undergoing sacrospinous ligament fixation for pelvic organ prolapse.

STUDY DESIGN

This was a retrospective observational study. All patients with vaginal apical repair with sacrospinous ligament fixation with preoperative TLUS were included. Demographics, clinical characteristics, and follow-up were analyzed. Multivariable logistic regression analysis was performed for composite outcome that included TLUS risk factors, age, Pelvic Organ Prolapse Quantification System measurements and stage, and variables with P < 0.1 in the univariate analysis.

RESULTS

Eighty-two patients were included. All patients had symptomatic vaginal bulge; 65.4% had stage III prolapse. Concomitant hysterectomy was performed in 54.3%. Median follow-up was 20 months (interquartile range, 8-35 months); 19.8% had LAM avulsion, and 43.2% had ballooning. Anatomic recurrence rate was 23.5%, symptomatic was 22.2%, and reoperation was 1.2%. The composite recurrence rate was 29.6%. In the multivariable logistic regression analysis, unilateral/bilateral avulsion in TLUS was found to be a significant risk factor for composite outcome with an odds ratio of 4.33 (confidence interval, 1.219-15.398; P = 0.023).

CONCLUSIONS

Composite outcome of recurrence in our study was 29.6%. Avulsion on TLUS increased the risk of recurrence of pelvic organ prolapse by fourfold.

Risk factors for pelvic organ prolapse recurrence following colpocleisis: A meta-analysis

BACKGROUND

Studies aimed to assess risk factors for pelvic organ prolapse (POP) recurrence following colpocleisis with nonconclusive results.

OBJECTIVE

To investigate risk factors for POP recurrence following colpocleisis.

SEARCH STRATEGY

MEDLINE, PUBMED, Embase, Web of Science, and Cochrane databases were systematically searched.

SELECTION CRITERIA

Experimental and non-experimental studies investigating POP recurrence following colpocleisis.

DATA COLLECTION AND ANALYSIS

We assessed the association between preoperative and postoperative physical examination findings, demographics and medical history, and the risk of recurrence following colpocleisis.

MAIN RESULTS

A total of 954 studies were identified, of which five studies comprising 2978 patients were eligible for analysis. Both preoperative and postoperative genital hiatus length were significantly longer in the recurrence group (mean difference [MD] 0.48, 95% confidence interval [CI] 0.01-0.94, P = 0.04, I2  = 0% and MD 1.15, 95% CI 0.50-1.81, P = 0.005, I2  = 0%; respectively). Preoperative total vaginal length (TVL) did not differ between groups (MD 0.05, 95% CI -0.40 to 0.50, P = 0.83, I2  = 6%), postoperative TVL was found significantly longer in the recurrence group (MD 0.07, 95% CI -0.03 to 1.38, P = 0.04, I2  = 68%). Both preoperative and postoperative perineal body did not differ between groups. Women with a previous POP surgery were more likely to experience recurrence following colpocleisis (relative risk 2.09, 95% CI 1.18-3.69, P = 0.01, I2  = 0%). Patient's age and previous hysterectomy did not affect recurrence rates.

CONCLUSION

Wider preoperative and postoperative genital hiatus as well as longer post-operative TVL and previous POP surgery were associated with a higher risk for recurrence following colpocleisis, highlighting the importance of appropriate patient selection and surgical technique in minimizing this risk.

Is the Presence of Levator Ani Muscle Avulsion Relevant for the Diagnosis of Uterine Prolapse?

OBJECTIVE

To determine if the addition of the assessment of levator ani muscle (LAM) avulsion to the measurement of the difference in the pubis-uterine fundus distance between rest and with the Valsalva maneuver could increase the diagnostic capacity of ultrasound for uterine prolapse (UP).

METHODS

This multicenter, observational and prospective study included 145 patients. Ultrasound assessment was performed, establishing the diagnosis of UP as a difference between the pubic-uterine fundus distance at rest and during the Valsalva maneuver ≥15 mm (standard technique), while LAM avulsion was defined as an abnormal LAM insertion in three central slices using multislice ultrasound. A binary multivariate logistic regression model was made using nonautomated methods to predict surgical UP (general population, premenopausal, and postmenopausal patients), including the difference between the pubis-uterine fundus distance at rest and with the Valsalva maneuver as well as LAM avulsion.

RESULTS

A total of 143 patients completed the study. The addition of LAM avulsion criteria to the standard dynamic distance-based protocol for the diagnosis of UP resulted in a higher sensitivity for the general population (79.7 vs 68.1%) as well as for premenopausal (89.3 vs 79.9%) and postmenopausal patients (76 vs 66.1%). In contrast, the standard technique showed a higher specificity than the model based on the standard technique associated with LAM avulsion for the general population (89.2 vs 74.3%) and premenopausal women (91.7 vs 63.2%). For postmenopausal patients, the model based on the standard technique associated with LAM avulsion had a higher sensitivity (76 vs 66.1%) and specificity (91.7 vs 86.8%) than the ultrasound diagnosis of UP.

CONCLUSION

The implementation of the assessment of LAM avulsion in the ultrasound diagnosis of UP is useful in postmenopausal patients, increasing sensitivity and specificity relative to the ultrasound assessment based only on the difference between the pubis-uterine fundus distance at rest and with the Valsalva maneuver.

Characteristics Associated With Surgical Failure After Native Tissue Apical Prolapse Repair

OBJECTIVE

To identify clinical and demographic characteristics associated with prolapse recurrence by 12 months after native tissue transvaginal repair.

METHODS

This was a planned secondary analysis of a randomized trial including postmenopausal participants with stage 2 or greater apical or anterior vaginal prolapse scheduled for surgical repair at three U.S. sites. Participants underwent vaginal hysterectomy (if uterus was present) and standardized uterosacral or sacrospinous ligament suspension at the surgeon's discretion. The intervention was perioperative (5 weeks or more preoperatively and 12 months postoperatively) vaginal estrogen compared with placebo cream. The primary outcome was time to failure by 12 months after surgery, defined by objective prolapse of the anterior or posterior walls beyond the hymen or the apex descending more than one-third of the vaginal length, symptomatic vaginal bulge, or retreatment. For this analysis, participants were grouped according to failure compared with success, and multiple factors were compared, including age, time since menopause, race and ethnicity, parity, body mass index (BMI), baseline genital hiatus measurement, prolapse stage and point of maximal prolapse, surgery type (uterosacral or sacrospinous ligament suspension), and concomitant procedures. Factors were assessed for association with the hazard of surgical failure using Cox proportional hazards models, adjusted for site and treatment group. Factors with P <.50 from this analysis were considered for inclusion in the final multivariable model; site and treatment group were kept in this model.

RESULTS

One hundred eighty-six participants underwent surgery; 183 provided complete data. There were 30 failures (16.4%) and 153 successes (83.4%) at 12 months. On bivariate analysis, failure was associated with decreasing age, shorter duration since menopause, Latina ethnicity, and greater baseline genital hiatus. In the final multivariable model, which included age, BMI, and point of maximal prolapse, only age remained significantly associated with surgical failure (adjusted hazard ratio [per year] 0.92, 95% CI, 0.86-0.98, P =.016).

CONCLUSION

Among postmenopausal women, younger age was associated with increased frequency of prolapse recurrence by 12 months after native tissue repair.

Validation of a built-in software in automatically reconstructing the tomographic images of the levator ani muscle

INTRODUCTION AND HYPOTHESIS

Transperineal ultrasound (TPUS) is an effective tool for evaluating the integrity of the levator ani muscle (LAM). Several operating steps are required to obtain the standard multi-slice image of the LAM, which is experience dependent and time consuming. This study was aimed at evaluating the feasibility and reproducibility of the built-in software, Smart-pelvic™, in reconstructing standard tomographic images of LAM from 3D/4D TPUS volumes.

METHODS

This study was conducted at a tertiary teaching hospital, enrolling women who underwent TPUS. Tomographic images of the LAM were automatically reconstructed by Smart-pelvicTM and rated by two experienced observers as standard or nonstandard. The anteroposterior diameter (APD) of the levator hiatus was also measured on the mid-sagittal plane of the automatically and manually reconstructed images. The APD measurements of each approach were compared using Bland-Altman plots, and interclass correlation coefficient (ICC) was used to evaluate intra- and inter-observer reproducibility. Meanwhile, the time taken for the reconstruction process of both methods was also recorded.

RESULTS

The ultrasound volume of a total of 104 patients were included in this study. Using Smart-pelvicTM, the overall success rate of the tomographic image reconstruction was 98%. Regarding measurements of APD, the ICC between the automatic and manual reconstruction methods was 0.99 (0.98, 0.99). The average time taken for reconstruction per case was 2.65 ± 0.52 s and 22.08 ± 3.45 s, respectively.

CONCLUSIONS

Using Smart-pelvicTM to reconstruct tomographic images of LAM is feasible, and it can promote TPUS by reducing operator dependence and improving examination efficiency in a clinical setting.

Immunobiology of foreign body response to composite PLACL/gelatin electrospun nanofiber meshes with mesenchymal stem/stromal cells in a mouse model: Implications in pelvic floor tissue engineering and regeneration

Pelvic Organ Prolapse (POP) is a common gynaecological disorder where pelvic organs protrude into the vagina. While transvaginal mesh surgery using non-degradable polymers was a commonly accepted treatment for POP, it has been associated with high rates of adverse events such as mesh erosion, exposure and inflammation due to serious foreign body response and therefore banned from clinical use after regulatory mandates. This study proposes a tissue engineering strategy using uterine endometrium-derived mesenchymal stem/stromal cells (eMSC) delivered with degradable poly L-lactic acid-co-poly ε-caprolactone (PLACL) and gelatin (G) in form of a composite electrospun nanofibrous mesh (P + G nanomesh) and evaluates the immunomodulatory mechanism at the material interfaces. The study highlights the critical acute and chronic inflammatory markers along with remodelling factors that determine the mesh surgery outcome. We hypothesise that such a bioengineered construct enhances mesh integration and mitigates the Foreign Body Response (FBR) at the host interface associated with mesh complications. Our results show that eMSC-based nanomesh significantly increased 7 genes associated with ECM synthesis and cell adhesion including, Itgb1, Itgb2, Vcam1, Cd44, Cdh2, Tgfb1, Tgfbr1, 6 genes related to angiogenesis including Ang1, Ang2, Vegfa, Pdgfa, Serpin1, Cxcl12, and 5 genes associated with collagen remodelling Col1a1, Col3a1, Col6a1, Col6a2, Col4a5 at six weeks post-implantation. Our findings suggest that cell-based tissue-engineered constructs potentially mitigate the FBR response elicited by biomaterial implants. From a clinical perspective, this construct provides an alternative to current inadequacies in surgical outcomes by modulating the immune response, inducing angiogenesis and ECM synthesis during the acute and chronic phases of the FBR.

Risk factors for the recurrence of pelvic organ prolapse: a meta-analysis

Female pelvic organ prolapse (POP) is a common condition, which has a high recurrence rate after reconstructive surgery, and the risk factors for POP recurrence are unclear. The aim of this study was to perform a meta-analysis to determine risk factors for POP recurrence. A thorough search of PubMed, Medline, EMBASE, Cochrane Central Register of Controlled Trials, and China Academic Journal Network Publishing Database was conducted for relevant publications until 29 October 2022, without language restrictions. A total of 29 studies involving 6597 patients were included, and the recurrence rate of POP after surgery was 37.7%. Significant OR and CI were found for levator avulsion (OR: 2.46, 95% CI: 1.80-3.36), preoperative stage ≥ III (OR: 1.87, 95% CI: 1.53-2.27), hiatal area on Valsalva manoeuvre (OR: 1.08, 95% CI: 1.03-1.12) and previous pelvic floor surgery (OR: 1.60, 95% CI: 1.07-2.39). Levator avulsion, preoperative stage ≥ III, hiatal area on Valsalva manoeuvre and previous pelvic floor surgery are significant risk factors for POP recurrence.IMPACT STATEMENTWhat is already known on this subject? It has been reported that genetic factors, parity, obesity, birth-induced injury during delivery, etc. are risk factors for POP development and recurrence after operation.What do the results of this study add? There are few literatures about the risk factors of POP recurrence at present. Our research has increased the information regarding risk factors for POP recurrence.What are the implications of these findings for clinical practice and/or further research? Our study provides an overview of the risk factors affecting POP recurrence and their contribution (OR, CI) to POP recurrence, which provides valuable evidence-based basis for clinical decision-making in POP treatment and prevention of POP recurrence.

Depth-Resolved Attenuation Mapping of the Vaginal Wall under Prolapse and after Laser Treatment Using Cross-Polarization Optical Coherence Tomography: A Pilot Study

Vaginal wall prolapse is the most common type of pelvic organ prolapse and is mainly associated with collagen bundle changes in the lamina propria. Neodymium (Nd:YAG) laser treatment was used as an innovative, minimally invasive and non-ablative procedure for the treatment of early-stage vaginal wall prolapse. The purpose of this pilot study was to assess connective tissue changes in the vaginal wall under prolapse without treatment and after Nd:YAG laser treatment using cross-polarization optical coherence tomography (CP OCT) with depth-resolved attenuation mapping. A total of 26 freshly excised samples of vaginal wall from 26 patients with age norm (n = 8), stage I-II prolapses without treatment (n = 8) and stage I-II prolapse 1-2 months after Nd:YAG laser treatment (n = 10) were assessed. As a result, for the first time, depth-resolved attenuation maps of the vaginal wall in the B-scan projection in the co- and cross-polarization channels were constructed. Two parameters within the lamina propria were target calculated: the median value and the percentages of high (≥4 mm-1) and low (<4 mm-1) attenuation coefficient values. A significant (p < 0.0001) decrease in the parameters in the case of vaginal wall prolapse compared to the age norm was identified. After laser treatment, a significant (p < 0.0001) increase in the parameters compared to the normal level was also observed. Notably, in the cross-channel, both parameters showed a greater difference between the groups than in the co-channel. Therefore, using the cross-channel achieved more reliable differentiation between the groups. To conclude, attenuation coefficient maps allow visualization and quantification of changes in the condition of the connective tissue of the vaginal wall. In the future, CP OCT could be used for in vivo detection of early-stage vaginal wall prolapse and for monitoring the effectiveness of treatment.

[Radiological imaging following pelvic prolapse surgery]

CLINICAL/METHODICAL ISSUE

Pelvic organ prolapse is a common condition in women, for which both conservative and surgical interventions are available. Knowledge of the different surgical procedures and the materials used is essential for adequate radiological diagnosis after prolapse surgery in order to differentiate potential complications from normal postoperative changes.

STANDARD RADIOLOGICAL METHODS

In the immediate postoperative period, computed tomography (CT) is often the modality of choice for evaluating acute complications such as bleeding or organ injuries. Magnetic resonance imaging (MRI) provides excellent soft tissue contrast and is therefore generally preferred for assessing subacute and chronic complications.

METHODICAL INNOVATIONS

Innovative techniques such as dynamic MRI protocols can improve the radiological assessment after prolapse surgery by enabling the evaluation of organ mobility.

PERFORMANCE

Radiological standard procedures such as computed tomography (CT) and MRI provide detailed and reliable information about the postoperative site and potential complications following prolapse surgery.

ACHIEVEMENTS

Radiological imaging plays an important role in the evaluation of patients after prolapse surgery, particularly when complications are suspected. Accurate radiological diagnosis can guide further appropriate therapeutic measures.

Outcomes of robotic sacrocolpopexy

This review aimed to summarize the complications and surgical outcomes of robot-assisted sacrocolpopexy. Nineteen original articles on 1,440 robotic sacrocolpopexies were reviewed, and three systematic reviews and meta-analyses were summarized in terms of intraoperative, perioperative, postoperative, and/or surgical outcomes. Robotic sacrocolpopexy has demonstrated low overall complication rates and favorable surgical outcomes. Nevertheless, long-term follow-up outcomes regarding objective and/or subjective prolapse recurrence, reoperation rates, and mesh-related complications remain unclear. Further research is required to demonstrate whether the robotic approach for sacrocolpopexy is feasible or can become the modality of choice in the future when performing sacrocolpopexy.

Twelve Month Outcomes of Pelvic Organ Prolapse Surgery in Patients With Uterovaginal or Posthysterectomy Vaginal Prolapse Enrolled in the Multicenter Pelvic Floor Disorders Registry

OBJECTIVE

The aim of the study was to compare 12-month subjective and objective outcomes between 3 approaches to apical pelvic organ prolapse (POP) surgery in patients presenting with uterovaginal or posthysterectomy vaginal prolapse enrolled in the Pelvic Floor Disorders Registry for Research.

STUDY DESIGN

This was an analysis of a multicenter, prospective registry that collected both patient- and physician-reported data for up to 3 years after conservative (pessary) and surgical treatment for POP. Twelve-month subjective and anatomic outcomes for patients who underwent surgical treatment were extracted from the registry for analysis. Pelvic organ prolapse recurrence was defined as a composite outcome and compared between the 3 apical surgery groups (native tissue repair, sacrocolpopexy, colpocleisis) as well as the 2 reconstructive surgery groups (native tissue repair and sacrocolpopexy).

RESULTS

A total of 1,153 women were enrolled in the registry and 777 (67%) opted for surgical treatment, of whom 641 underwent apical repair and were included in this analysis (404 native tissue repair, 187 sacrocolpopexy, and 50 colpocleisis). The overall incidence of recurrence was as follows: subjective 6.5%, anatomic 4.7%, retreatment 7.2%, and composite 13.6%. The incidence of recurrence was not different between the 3 surgical groups. When baseline patient characteristics were controlled for, composite POP recurrence between the native tissue and sacrocolpopexy groups remained statistically nonsignificant. Concurrent perineorrhaphy with any type of apical POP surgery was associated with a lower risk of recurrence (adjusted odds ratio, 0.43; 95% confidence interval, 0.25-0.74; P = 0.002) and prior hysterectomy was associated with a higher risk (adjusted odds ratio, 1.77, 95% confidence interval, 1.04-3.03; P = 0.036).

CONCLUSION

Pelvic Floor Disorders Registry for Research participants undergoing native tissue apical POP repair, sacrocolpopexy, and colpocleisis surgery had similar rates of POP recurrence 12 months after surgery.

Association between the rs1036819 polymorphism of the ZFAT gene and pelvic organ prolapse: a case-control study

INTRODUCTION AND HYPOTHESIS

The identification of risk factors for pelvic organ prolapse (POP) would contribute to planning prevention strategies. This study tests the hypothesis that the rs1036819 polymorphism in the ZFAT gene is associated with POP and investigates other risk factors for prolapse development.

METHODS

A case-control study was carried out including 826 postmenopausal women divided into POP cases (stages III and IV) and controls (stages 0 and I), assessed by anamnesis, examination, and peripheral blood samples. DNA was extracted from blood and genotyped by real-time RT-PCR. We used logistic regression models for the association analyses of variables, with p < 0.05 for significance.

RESULTS

Five hundred and sixty-eight women were evaluated (315 POP and 253 controls). The minor allele C was found in 19.3% of our sample and the genotype frequencies of AA, AC, and CC were similar in both groups. Age (OR 1.09, 95% CI 1.06-1.13), number of pregnancies (OR 1.23, 95% CI 1.08-1.41), history of one vaginal delivery (OR 3.39, 95% CI 1.38-8.33) or two or more (OR 2.51, 95% CI 1.04-6.07), weight of the largest newborn (OR 1.0001, 95% CI 1-1.001), and family history of POP (OR 2.27, 95% CI 1.24-4.13) were independent risk factors for POP, whereas one cesarean section (OR 0.48, 95% CI 0.27-0.88) or two or more (OR 0.14, 95% CI 0.05-0.38) were protective.

CONCLUSIONS

No association was detected between the rs1036819 polymorphism of the ZFAT gene and advanced POP. Age, number of pregnancies, at least one vaginal delivery, weight of the newborn, and POP family history were independent risk factors for POP.

Identification of potential molecular mechanisms and therapeutic targets for recurrent pelvic organ prolapse

Background

The pathogenesis of recurrent pelvic organ prolapse (POP) is currently unclear. Therefore, developing targeted preventive measures is difficult. This study identified potential key pathways, crucial genes, comorbidities, and therapeutic targets associated with the occurrence and development of recurrent POP.

Methods

The original microarray data GSE28660, GSE53868, and GSE12852 were downloaded from the GEO database. Identification and validation of differentially expressed genes (DEGs) and hub genes associated with recurrent POP were performed using R software and cytoHubba of Cytoscape. Protein-protein interaction (PPI) networks were constructed using the STRING tool and visualized using Cytoscape. Gene ontology (GO) and Kyoto Encyclopedia of Gene and Genome (KEGG) enrichment analyses were effectively performed using DAVID platforms. In addition, the NetworkAnalyst platform was used to explore and visualize the miRNA-hub gene network, TF-hub gene network, hub gene-disease network, and hub gene-drug/chemical network.

Results

A total of 110 DEGs and 6 hub genes (ADIPOQ, IL6, PPARG, CEBPA, LPL, and LIPE) were identified in this study. These genes were primarily enriched in the PPAR, AMPK, and adipocytokine, non-alcoholic fatty liver disease, and signaling pathways related to glycerol metabolism. Moreover, 96 miRNAs and 97 TFs were identified to as being associated with recurrent POP. These genes were closely linked to adipocyte metabolism and distribution, energy metabolism, and the longevity regulatory pathway. In addition, 192 diseases or chronic complications were potentially related to the recurrence of POP, including diabetes, hypertension, obesity, inflammatory diseases, and chronic obstructive pulmonary disease. Furthermore, 954 drugs or compounds were shown to have therapeutic potential for recurrent POP, and the most critical target drugs were dexamethasone, bisphenol A, efavirenz, 1-methyl-3-isobutylxanthine, and estradiol.

Conclusions

The results of this study revealed that ADIPOQ, IL6, PPARG, CEBPA, LPL, and LIPE as potential hub genes associated with recurrent POP, and these hub genes may aid in the understanding of the mechanism underlying POP recurrence and the development of potential molecular drugs.

The impact of diabetes mellitus on pelvic organ prolapse recurrence after robotic sacrocolpopexy

INTRODUCTION AND HYPOTHESIS

Data examining the effect of diabetes mellitus (DM) on prolapse recurrence after sacrocolpopexy (SCP) is limited. The primary objective of this study was to determine if DM affects prolapse recurrence after robotic SCP.

METHODS

This was a retrospective cohort study of women who underwent robotic SCP between 2012 and 2019 at Kaiser Permanente Southern California. The cohort was divided into women with and without DM at the time of SCP. The primary outcome was composite failure. Secondary outcomes included recurrent compartment-specific prolapse, reoperation rates, and surgical complications.

RESULTS

Of 547 patients included, 100 had DM. Women with DM were older, had higher BMI, higher parity, and were more likely to be nonwhite. Women with DM had more advanced prolapse at baseline but were not more likely to undergo concomitant procedures at the time of SCP. Over a median follow-up of 2.1 years (IQR 1.3, 3.4), women with DM had significantly increased risk of anterior vaginal prolapse (AVP) recurrence (13% vs 3%, p<0.01), but not composite failure (21% vs 14%, p=0.14). On multivariate regression, women with DM were almost 4 times as likely to experience AVP recurrence over time (AVP hazard ratio (HR) 3.93, 95% CI 1.29-12.03, p=0.02).

CONCLUSION

In our cohort, DM was a risk factor for AVP recurrence but not composite failure after robotic SCP.

Four vertex technique for correcting urethral prolapse: technique description and cohort study

Introduction/Objectives

This study aims to describe the procedure and effectiveness of the four-vertex technique for correcting urethral prolapse in women.

Methods and Materials

includes a retrospective case series of 17 patients who underwent surgery for urethral prolapse. Two study groups were distinguished based on the presence or absence of pelvic heaviness symptoms. The variables were analyzed, including age, BMI, concomitant diseases, obstetric and gynecological history, time from diagnosis to surgery, and outcomes of treatment.

Results

All patients were postmenopausal, with a mean age at the time of the intervention of 70.41 years, with no differences between groups. Mean BMI was 23.67 kg/m2, higher in the group with a sensation of vaginal heaviness (p = 0.027). Mean time elapsed between diagnosis and operation was 231.58 days, with no differences between groups. Mean childbirth count was 2.29. The most frequent causes for consultation were urethrorrhagia (33.33%) and a bulging sensation (33.33%). After the intervention, 14 patients (82.35%) were asymptomatic, two (11.76%) had dysuria, and one (5.88%) had urinary urgency. Ten patients had pre-surgical urinary incontinence, which was resolved in nine patients. 17.46% subsequently presented pelvic organ prolapse. In three women there was secondary impairment of sexual activity.

Conclusion

The four-vertex technique was effective in resolving symptoms in most patients. However, some patients experienced dysuria, urinary urgency, and pelvic organ prolapse after surgery. Urinary incontinence improved in most patients, but a few required additional treatments with suburethral tape. The study also identified associations between variables and the presence of cystocele, consultation for a bulging sensation, and bleeding from urethral prolapse. Overall, this study sheds light on the challenges and outcomes of surgical treatment for urethral prolapse and provides valuable insights for future research in this area.

Diagnosis of maternal birth trauma by pelvic floor ultrasound

BRIEF SUMMARY

Maternal somatic birth trauma due to vaginal delivery is more common than generally assumed and an important cause of future morbidity. Maternal birth trauma may involve both psychological and somatic morbidity, some of it long-term and permanent. Somatic birth trauma is now understood to encompass not just episiotomy, perineal tears and obstetric anal sphincter injuries (OASI), but also trauma to the levator ani muscle, termed 'avulsion'. This review will focus on recent developments in the imaging diagnosis of maternal birth trauma, discuss the most important risk factors and strategies for primary and secondary prevention. Translabial and exo-anal ultrasound allow the assessment of maternal birth trauma in routine clinical practice and enable the use of levator avulsion and anal sphincter trauma as key performance indicators of maternity services. This is likely to lead to a greater awareness of maternal birth trauma amongst maternity caregivers and improved outcomes for patients, not the least due to an increasing emphasis on patient autonomy and informed consent in antenatal and intrapartum care.

Effect of Vitamin D analog supplementation on levator ani strength and plasma Vitamin D receptor expression in uterine prolapse patients

Uterine prolapse is a pathological condition that can negatively impact women's quality of life. It is caused by weakening of the pelvic floor muscles. Function of levator ani muscle and other striated muscles is thought to be influenced by Vitamin D levels. Vitamin D exerts its biological effects by adhering to Vitamin D receptors (VDRs) present in striated muscles. We aim to analyze the effect of Vitamin D analog supplementation on levator ani muscle strength in uterine prolapse patients. This was a quasi-experimental study with a pre-post design on 24 postmenopausal women diagnosed with grade III and IV uterine prolapse. Vitamin D levels, VDR, levator ani muscle, and hand grip muscle strength were measured before and after three months of Vitamin D analog supplementation. We found that Vitamin D level, VDR serum level, levator ani muscle strength, and hand grip muscle strength all significantly increase (p < 0.001) following Vitamin D analog supplementation. The correlation coefficient between levator ani muscle and handgrip muscle strength was 0.616 and with p value of 0.001. To conclude, Vitamin D analog supplementation can significantly increase levator ani muscle strength in uterine prolapse patients. We propose that determining Vitamin D level in postmenopausal women and replenishing its deficiency with Vitamin D analog supplementation might aid in preventing POP progression.

Clinical outcomes and complications of laparoscopic sacrocolpopexy with versus without concomitant hysterectomy for pelvic organ prolapse in Hong Kong Chinese patients after median follow-up of 7 years

INTRODUCTION AND HYPOTHESIS

This retrospective cohort study is aimed at comparing outcomes and complications of laparoscopic sacrocolpopexy (LSC) with or without concomitant hysterectomy in the Hong Kong Chinese population.

METHODS

Women with stage II or above uterine or apical vault prolapse who underwent LSC with or without concomitant hysterectomy in a regional referral unit from 2007 to 2019 were included. The primary objectives were to compare the anatomical outcomes by pelvic organ prolapse quantification system (POP-Q) and recurrence of apical vault prolapse (≥stage II). The secondary objective was to compare the functional outcomes and complications. Anatomical recurrence and incidence of mesh exposure were analyzed using the Kaplan-Meier method. Cox proportional hazard regression was performed to identify risk factors of anatomical recurrence.

RESULTS

Seventy-six women were included for analysis. The recurrence rate of apical vault prolapse was 3.9% after a median follow-up time of 83 months (20-190 months). A significant reduction of POP-Q scores of three compartments in both groups of women were demonstrated (p<0.001). There was no difference between the two groups in terms of functional outcomes and complications. 6.6% of women developed mesh exposure. The time to recurrence of apical vault prolapse was shorter in women who had LSC with prior hysterectomy (p =0.019). No risk factors were identified for recurrence of apical vault prolapse.

CONCLUSIONS

Laparoscopic sacrocolpopexy with concomitant hysterectomy is comparable with LSC alone. The recurrence and complication rates are low. We suggest that LSC with concomitant hysterectomy might be offered to women with pelvic organ prolapse, with women's preference taken into account.

Characteristics associated with composite surgical failure over 5 years of women in a randomized trial of sacrospinous hysteropexy with graft vs vaginal hysterectomy with uterosacral ligament suspension

BACKGROUND

Among women with symptomatic uterovaginal prolapse undergoing vaginal surgery in the Vaginal hysterectomy with Native Tissue Vault Suspension vs Sacrospinous Hysteropexy with Graft Suspension (Study for Uterine Prolapse Procedures Randomized Trial) trial, sacrospinous hysteropexy with graft (hysteropexy) resulted in a lower composite surgical failure rate than vaginal hysterectomy with uterosacral suspension over 5 years.

OBJECTIVE

This study aimed to identify factors associated with the rate of surgical failure over 5 years among women undergoing sacrospinous hysteropexy with graft vs vaginal hysterectomy with uterosacral suspension for uterovaginal prolapse.

STUDY DESIGN

This planned secondary analysis of a comparative effectiveness trial of 2 transvaginal apical suspensions (NCT01802281) defined surgical failure as either retreatment of prolapse, recurrence of prolapse beyond the hymen, or bothersome prolapse symptoms. Baseline clinical and sociodemographic factors for eligible participants receiving the randomized surgery (N=173) were compared across categories of failure (≤1 year, >1 year, and no failure) with rank-based tests. Factors with adequate prevalence and clinical relevance were assessed for minimally adjusted bivariate associations using piecewise exponential survival models adjusting for randomized apical repair and clinical site. The multivariable model included factors with bivariate P<.2, additional clinically important variables, apical repair, and clinical site. Backward selection determined final retained risk factors (P<.1) with statistical significance evaluated by Bonferroni correction (P<.005). Final factors were assessed for interaction with type of apical repair at P<.1. Association is presented by adjusted hazard ratios and further illustrated by categorization of risk factors.

RESULTS

In the final multivariable model, body mass index (increase of 5 kg/m2: adjusted hazard ratio, 1.7; 95% confidence interval, 1.3-2.2; P<.001) and duration of prolapse symptoms (increase of 1 year: adjusted hazard ratio, 1.1; 95% confidence interval, 1.0-1.1; P<.005) were associated with composite surgical failure, where rates of failure were 2.9 and 1.8 times higher in women with obesity and women who are overweight than women who have normal weight and women who are underweight (95% confidence intervals, 1.5-5.8 and 0.9-3.5) and 3.0 times higher in women experiencing >5 years prolapse symptoms than women experiencing ≤5 years prolapse symptoms (95% confidence interval, 1.8-5.0). Sacrospinous hysteropexy with graft had a lower rate of failure than hysterectomy with uterosacral suspension (adjusted hazard ratio, 0.6; 95% confidence interval, 0.4-1.0; P=.05). The interaction between symptom duration and apical repair (P=.07) indicated that failure was less likely after hysteropexy than hysterectomy for those with ≤5 years symptom duration (adjusted hazard ratio, 0.5; 95% confidence interval, 0.2-0.9), but not for those with >5 years symptom duration (adjusted hazard ratio, 1.0; 95% confidence interval 0.5-2.1).

CONCLUSION

Obesity and duration of prolapse symptoms have been determined as risk factors associated with surgical failure over 5 years from transvaginal prolapse repair, regardless of approach. Providers and patients should consider these modifiable risk factors when discussing treatment plans for bothersome prolapse.

Impact of Laparoscopic Prolapse Repair in the Levator Hiatus Area

STUDY OBJECTIVE

To determine whether laparoscopic surgery by sacrocolpopexy or sacrocervicopexy with posterior mesh attachment to levator ani to treat pelvic organ prolapse reduces the levator hiatus area, as measured by transperineal 3- and 4-dimensional ultrasound. The secondary objective was to assess the risk factors for prolapse recurrence.

DESIGN

This is a prospective cohort study.

SETTING

A university tertiary hospital.

PATIENTS

Women with symptomatic apical prolapse at a high risk of recurrence were included. High risk of recurrence was defined as age <60 years and levator injury (avulsion and/or ballooning) or stage III-IV prolapse Pelvic Organ Prolapse Quantification.

INTERVENTIONS

Women were treated with laparoscopic sacrocolpopexy or sacrocervicopexy.

MEASUREMENTS AND MAIN RESULTS

Women underwent clinical examination according to assessment by the Pelvic Organ Prolapse Quantification system and transperineal ultrasound for the levator hiatus area at Valsalva. We collected demographic, clinical, and ultrasound data before surgery from clinical records and performed a comparative analysis of the levator hiatus areas before and after surgery and univariate and multivariate analyses of the risk factors for recurrence. Among the 30 women who enrolled, the levator hiatus area at Valsalva decreased significantly after surgery by an average of 4.68 cm² (p = .028). However, despite a recurrence rate of 13.3%, we found no risk factors associated with recurrence in either the univariate or the multivariate analyses.

CONCLUSION

Laparoscopic surgery by sacrocolpopexy or sacrocervicopexy for pelvic organ prolapse with mesh posterior attachment to levator ani significantly reduces the levator hiatus area measured by transperineal ultrasound. Further large-scale studies will be needed to confirm our results and identify risk factors for recurrence.

The Vaginal Patch Plastron Associated to the Anterior Sacrospinous Ligament Fixation for the Treatment of Advanced Anterior Vaginal Wall Prolapse

Background: this study aims to compare the efficacy and safety of vaginal patch plastron (VPP) associated to anterior sacrospinous ligament fixation (SSLF-A) with SSLF-A associated or not to the anterior colporrhaphy (AC) for cystocele treatment. Methods: single-center retrospective study in women with cystocele ≥ III stage submitted to surgery. The primary outcome was to compare objective and subjective cystocele relapse and reoperation rate at follow-up > 6 months. The secondary outcome was to describe peri- and postoperative complications and risk factors for cystocele objective relapse. Results: 75 women were submitted to SSLF-A and 61 women to VPP. VPP objective and subjective relapse (6.5%, 4/61 and 1.1%, 1/61) were lower than SSLF-A (26.7%, 20/75 and 20%, 15/75; p = 0.002 and p = 0.001, respectively). SSLF-A had a higher reintervention rate, but not significantly (6.6%, 5/75 vs. 0%, 0/61; p = 0.06). Previous hysterectomy was a risk factor (HR 4; 1.3−12.1) while VPP was protective factor (HR 0.2; 0.1−0.9) for cystocele anatomical relapse. Postoperative buttock pain was more prevalent in VPP (57.4%, 35/75 vs. 34.7%, 26/61; p = 0.01). Conclusions: VPP is effective and safe for advanced cystocele treatment, with lower objective and subjective relapse rates in comparison to isolated SSLF-A or associated with the AC.

All or nothing? A second look at partial levator avulsion

OBJECTIVE

To define associations between partial levator trauma and symptoms and signs of pelvic organ prolapse (POP).

METHODS

This was a retrospective study of 3484 women attending a tertiary urogynecology unit for symptoms of pelvic floor dysfunction between January 2012 and February 2020. All women underwent a standardized interview, clinical pelvic organ prolapse quantification (POP-Q) examination and tomographic ultrasound imaging of the pelvic floor. Women with full levator avulsion were excluded from analysis. Partial levator avulsion was quantified using the tomographic trauma score (TTS), in which slices 3-8 are scored bilaterally for abnormal insertions. Binomial multiple logistic regression was analyzed independently for the outcome variables prolapse symptoms, symptom bother and objective prolapse on clinical examination and imaging, with age and body mass index as covariates. Two continuous outcome variables, prolapse bother score and hiatal area on Valsalva, were analyzed using multiple linear regression.

RESULTS

Of the 3484 women, ultrasound data were missing or incomplete in 164 due to lack of equipment, clerical error and/or inadequate image quality. Full levator avulsion was diagnosed in 807 women, leaving 2513 for analysis. TTS ranged from 0-10, with a median of 0. Partial trauma (TTS > 0) was observed in 667/2513 (26.5%) women. All subjective and objective measures of POP were associated significantly with TTS, most strongly for cystocele. Associations were broadly linear and similar for all slice locations but disappeared after accounting for hiatal area on Valsalva.

CONCLUSION

Partial avulsion is associated with POP and prolapse symptoms. This association was strongest for cystocele, both on POP-Q and ultrasound imaging. The effect of partial avulsion on POP and prolapse symptoms is explained fully by its effect on hiatal area. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Long-Term Outcomes after Pelvic Organ Prolapse Repair in Young Women

The aim of the study was to describe the long-term outcomes of Pelvis Organ Prolapse (POP) repair in women under 40 years old. A retrospective chart review of all POP repairs performed in women ≤40 years old between January 1997 and December 2015 in the Gynecologic Surgery Department of Lille University Hospital was performed. Inclusion criteria were all women ≤40 years old who underwent a POP repair with a stage ≥2 POP according to the Baden and Walker classification. The study population was separated into three groups: a sacrohysteropexy group, a vaginal native tissue repair (NTR) group, and a transvaginal mesh surgery (VMS) group. The primary outcome was reoperation procedures for a symptomatic recurrent POP. Secondary outcomes were other complications. During the study period, 43 women ≤ 40 years old who underwent a POP repair were included and separated into three groups: 28 patients (68%), 8 patients (19%), and 7 patients (16%) in the sacrohysteropexy, VMS, and NTR groups respectively. The mean followup time was 83 ± 52 months. POP recurrence, reoperated or not, was essentially diagnosed in the VMS group (87.5%) and the NTR group (50%). POP recurrence repairs were performed for nine patients (21%): 7%, 62.5%, and 25% in the sacrohysteropexy, VMS, and NTR groups, respectively. Global reoperation concerned 10 patients (23%) whatever the type of POP surgery, mainly patients from the VMS group (75%) and from the NTR group (25%). It occurred in only 7% of patients from the sacrohysteropexy group. Two patients (4%) presented a vaginal exposure of the mesh (in the VMS group). De novo stress urinary incontinence was encountered by nine patients (21%): 29% and 12.5% in the sacrohysteropexy and NTR groups, respectively. Despite the risk of recurrence, POP repair should be proposed to young women in order to restore their quality of life. Vaginal native tissue repair or sacrohysteropexy should be performed after explaining to women the advantages and disadvantages of each procedure.

Risk factors of pelvic organ prolapse at Asella Teaching and Referral Hospital: Unmatched case control study

Background

Prolapse is one of the sub-types of pelvic floor dysfunction (PFD) which occurs due to abnormal fall of the pelvic organs from their normal anatomic positions. Although the cause of prolapse is multifactorial, it primarily occurs due to pregnancy and vaginal delivery. Hence, the present study aimed to identify risk factors of prolapse among women who undergo gynecological surgery.

Materials and methods

Facility-based-unmatched case–control design was employed. Cases were all gynecological women who were diagnosed with pelvic organ prolapse (POP) at Asella teaching referral hospital (ATRH) while controls were all charts of gynecological women who were diagnosed with other gynecological problems rather than POP at ATRH. For each case, two controls were selected using a simple random sampling technique. The data were entered into Epidata version 4.3.1 and finally exported to SPSS version 25 for further analysis. Then variables that had an association in the bivariate model (p &lt; 0.25) were entered and analyzed by a multivariable conditional logistic regression model to identify the independent effect of different factors. Statistical significance was declared at p &lt; 0.05.

Results

A total of 147 cases and 293 controls were included in this study. Women who had a history of chronic cough, previous pelvic floor surgery, constipation, and vaginal tear during delivery, history of pelvic trauma, age of the women, rural resident, and maternal gravidity were strongly associated with prolapse at p-value of &lt; 0.05. Multigravida [adjusted odds ratio (AOR) 2.987 (95% CI 1.237–6.853), p = 0.014], age &gt;50 years [AOR: 2.496 (95% CI 1.372–4.539), p = 0.003], women with a history of pelvic floor surgery [AOR: 0.3.666 (95% CI 1.328–10.124), p = 0.012], women who had diabetes mellitus [AOR: 4.676 (95% CI 0.908–24.075), p = 0.065], and resided in rural areas [AOR = 1.878; (95% CI: 0.984–3.585), I2 = 47.5%, p = 0.056] were the independent predictors were of prolapse.

Conclusions

In this study, women with diabetes mellitus, previous pelvic floor surgery, rural residents, being multigravida, and age &gt;40 were independent predictors of prolapse. Therefore, delivering health education by focusing on the identified risk factors was strongly recommended.

The Application of a Multidimensional Prediction Model in the Recurrence of Female Pelvic Organ Prolapse after Surgery

Objective

The relationship between multiple indicators of women and postoperative recurrence of pelvic organ prolapse was analyzed to establish a model for predicting postoperative recurrence of female pelvic organ prolapse.

Methods

Three hundred patients with pelvic organ prolapse who underwent pelvic organ prolapse surgery at our hospital were monitored for 1-2 years to determine their prognosis. Whether there was a postoperative recurrence, they were divided into two groups. We collected the relevant data from the two groups of patients before and after surgery. Through single factor and logistic multivariate analysis, we selected the risk factors that may affect the recurrence of patients to construct a prediction model. We verified the identification ability, proofreading ability, and clinical applicability of the model.

Results

Eighty-four patients with pelvic organ prolapse who had postoperative recurrence were assigned to the recurrence group, and 216 patients were included in the nonrecurrence group. Based on the logistic multivariate analysis results, we constructed a nomogram model containing 5 dimensions of age, BMI, degree of prolapse, pubic fissure, and serum calcium to predict postoperative recurrence. The tests revealed that the model had an excellent identification ability (AUC = 0.910), and the expected recurrence rate was significantly in agreement with the actual recurrence rate (U = -0.007, Brief = 0.087). The Hosmer-Lemeshow goodness-of-fit test demonstrated that the model had good calibration (c2 = 29.352, P = 0.522), and the decision curve showed that the threshold probability was in the range of ~12% to 100%, having a high net benefit value.

Conclusion

Based on the present study findings, we concluded that the constructed nomogram model has suitable identification, calibration, and clinical applicability.

Are anterior mesh arms necessary in Japanese-style transvaginal mesh surgery for cystocele?

AIM

In this study, we retrospectively analyzed the medium-term efficacy and safety of surgery with transobturator two-arm transvaginal mesh for cystocele and to verify whether the anterior arms are necessary for Japanese-style transvaginal mesh surgery.

METHODS

The study included 203 patients with cystocele who underwent transobturator two-arm transvaginal mesh at our hospital between August 2015 and June 2017 and received appropriate follow-up care for at least 48 months after surgery.

RESULTS

The Pelvic Organ Prolapse Quantification stage was III in all the patients. Intraoperative complications included two cases of bladder injury and one case of more than 200 mL of blood loss. The mean observation period was 51.9 months, and prolapse recurred in the operated compartment in nine patients (4.4%). No cases of mesh exposure were observed. In comparing the preoperative characteristics of the 9 patients with prolapse recurrence at the surgical site with those of the other 194 patients, we found that the recurrence rate was significantly higher among patients in whom point Ba being 3.5 cm or more and among patients younger than 66 years.

CONCLUSIONS

Transobturator two-arm transvaginal mesh for cystocele was as good and safe as the procedure previously reported with four-arm mesh; thus, it was possible to omit the anterior mesh arms in Japanese-style transvaginal mesh surgery. Patients should be informed preoperatively that prolapse recurs at a significantly higher rate among younger patients and in those whose point Ba being 3.5 cm or more.

Is levator ani avulsion a risk factor for prolapse recurrence? A systematic review and meta-analysis

Introduction and hypothesis

Levator ani muscle avulsion as a risk factor for prolapse recurrence is not well established. This systematic review was aimed at evaluating the correlation between levator ani avulsion and postoperative prolapse recurrence with meta-analysis, specifically, the risk of subjective or objective prolapse recurrence and reoperation.

Methods

The protocol was registered in the International Prospective Register of Systematic Reviews (registration number CRD42021256675). A systematic literature search was conducted using PubMed, EMBASE and Cochrane Database of Systematic Reviews to identify all peer-reviewed studies that described levator avulsion in women and investigated operative and postoperative outcomes. All peer-reviewed, English-language cohort studies in those with and without levator avulsion with a minimum of 3 months’ follow-up were included. Pooled unadjusted and adjusted odds ratios were calculated for subjective recurrence, objective recurrence and rates of re-operation. The Cochrane Collaboration Risk of Bias In Non-Randomized Studies (RoBINS) and The Grading of Recommendations Assessment, Development and Evaluation (GRADE) tools were used to assess the quality of the studies included.

Results

Twelve studies with a total of 2,637 subjects and a follow-up period 0.3–6.4 years were identified. There were insufficient data to report a pooled adjusted risk for subjective recurrence and reoperation. On low to moderate quality-adjusted data, the pooled odds of objective recurrence was not significantly associated with levator ani avulsion (aOR 1.68; 95% CI 0.78–3.66).

Conclusion

Levator ani avulsion has not been confirmed as a risk factor for objective prolapse recurrence. Further evidence is needed to investigate the correlation between levator ani avulsion and the risk of subjective recurrence and reoperation.

Vaginal vault prolapse and recurrent surgery: A nationwide observational cohort study

INTRODUCTION

In surgical repair of pelvic organ prolapse the recurrence rate is about 30% and the importance of apical support was recently highlighted. In surgical randomized controlled studies, the external validity can be compromised because the surgical outcomes often depend on surgical volume. Therefore, we sought to study outcomes of surgical treatment in patients with vaginal vault prolapse in a nationwide setting with a variety of surgical volumes.

MATERIAL AND METHODS

This is a nationwide cohort study. All patients with a vaginal vault prolapse undergoing surgery, between January 1, 2015 and December 31, 2018, were identified from the Swedish National Quality Register of Gynecological Surgery, GynOp. The primary outcome was the frequency of recurrent pelvic organ prolapse surgery within 2 years postoperatively. Secondary outcomes included patient-reported vaginal bulging, operative time, estimated blood loss and 1-year postoperative complications.

RESULTS

In 1812 patients with vaginal vault prolapse, 538 (30%) had a sacrospinous ligament fixation (SSLF) with graft, 441 (24%) underwent SSLF without graft, and 200 (11%) underwent minimally invasive sacrocolpopexy (SCP) or sacrocervicopexy (SCerP). A significantly higher proportion of patients undergoing recurrent pelvic organ prolapse surgery was seen in SSLF without graft than in SSLF with graft (adjusted odds ratio [aOR] 2.2, 95% CI 1.4-3.6). Patient-reported sensation of vaginal bulging 1 year after surgery was higher in the SSLF group without graft than in the SSLF group with graft (aOR 1.9, 95% CI 1.3-2.8) and in the SCP/SCerP group (aOR 2.0, 95% CI 1.1-3.4). Finally, we found a significantly higher rate of complications 1 year after surgery in SSLF without graft (aOR 2.3, 95% CI 1.2-4.2) and in SSLF with graft (aOR 2.2, 95% CI 1.2-4.2) compared with SCP/SCerP.

CONCLUSIONS

In patients with vaginal vault prolapse, SSLF without graft was associated with a higher frequency of recurrent pelvic organ prolapse surgery compared with SSLF with graft, and a higher subjective relapse rate compared with SCP/SCerP and SSLF with graft. Additionally, the complication rate 1 year after primary surgery was higher in SSLF both with and without graft than in SCP/SCerP.

Risk factors for primary pelvic organ prolapse and prolapse recurrence: an updated systematic review and meta-analysis

OBJECTIVE

To update a previously published systematic review and perform a meta-analysis on the risk factors for primary pelvic organ prolapse and prolapse recurrence.

DATA SOURCES

PubMed and Embase were systematically searched. We searched from July 1, 2014 until July 5, 2021. The previous search was from inception until August 4, 2014.

STUDY ELIGIBILITY CRITERIA

Randomized controlled trials and cross-sectional and cohort studies conducted in the Western developed countries that reported on multivariable analysis of risk factors for primary prolapse or prolapse recurrence were included. The definition of prolapse was based on anatomic references, and prolapse recurrence was defined as anatomic recurrence after native tissue repair. Studies on prolapse recurrence with a median follow-up of ≥1 year after surgery were included.

METHODS

Quality assessment was performed with the Newcastle-Ottawa Scale. Data from the previous review and this review were combined into forest plots, and meta-analyses were performed where possible. If the data could not be pooled, "confirmed risk factors" were identified if ≥2 studies reported a significant association in multivariable analysis.

RESULTS

After screening, 14 additional studies were selected-8 on the risk factors for primary prolapse and 6 on prolapse recurrence. Combined with the results from the previous review, 27 studies met the inclusion criteria, representing the data of 47,429 women. Not all studies could be pooled because of heterogeneity. Meta-analyses showed that birthweight (n=3, odds ratio, 1.04; 95% confidence interval, 1.02-1.06), age (n=3, odds ratio, 1.34; 95% confidence interval, 1.23-1.47), body mass index (n=2, odds ratio, 1.75; 95% confidence interval, 1.17-2.62), and levator defect (n=2, odds ratio, 3.99; 95% confidence interval, 2.57-6.18) are statistically significant risk factors, and cesarean delivery (n=2, pooled odds ratio, 0.08; 95% confidence interval, 0.03-0.20) and smoking (n=3, odds ratio, 0.59; 95% confidence interval, 0.46-0.75) are protective factors for primary prolapse. Parity, vaginal delivery, and levator hiatal area are identified as "confirmed risk factors." For prolapse recurrence, preoperative prolapse stage (n=5, odds ratio, 2.68; 95% confidence interval, 1.93-3.73) and age (n=2, odds ratio, 3.48; 95% confidence interval, 1.99-6.08) are statistically significant risk factors.

CONCLUSION

Vaginal delivery, parity, birthweight, age, body mass index, levator defect, and levator hiatal area are risk factors, and cesarean delivery and smoking are protective factors for primary prolapse. Preoperative prolapse stage and younger age are risk factors for prolapse recurrence after native tissue surgery.

The rs2165241 polymorphism of the Loxl1 gene in postmenopausal women with pelvic organ prolapse

OBJECTIVE

This study aimed to verify the presence of polymorphism rs2165241 of the lysyl oxidase-like 1 (Loxl1) gene and its association with pelvic organ prolapse (POP) in Brazilian women and determine risk factors for POP development.

METHODS

The study was previously approved by the local research and ethics board. Postmenopausal women were included and divided into POP (stages III and IV) and control (stages 0 and I) groups. Peripheral blood samples were collected, and the DNA sequence of interest was analyzed by real-time reverse-transcriptase polymerase chain reaction. We used logistic regression and considered a recessive model of inheritance for the analysis, with p < 0.05 for significance.

RESULTS

A total of 836 women were assessed: 426 POP cases and 410 controls. The frequencies of CC, CT and TT genotypes were similar in both groups. Age (odds ratio [OR] = 1.1, 95% confidence interval [CI] = 1.07; 1.14), number of vaginal births (OR = 17.06, 95% CI = 5.94; 48.97), family history (OR = 2.87, 95% CI = 1.57; 5.22) and weight of largest newborn (OR = 1.001, 95% CI = 1.0003; 1.001) were independent risk factors for POP, while multiple cesarean sections (two or more) was protective (OR = 0.17, 95% CI = 0.07; 0.42).

CONCLUSION

No association was detected between rs2165241 of the Loxl1 gene and POP.

Risk factors for pelvic organ prolapse recurrence after sacrospinous hysteropexy or vaginal hysterectomy with uterosacral ligament suspension

BACKGROUND

Given that the number of surgeries for pelvic organ prolapse is expected to increase worldwide, knowledge on risk factors for prolapse recurrence is of importance for developing preventive strategies and shared decision-making.

OBJECTIVE

To identify risk factors for subjective and objective failure after either sacrospinous hysteropexy or vaginal hysterectomy with uterosacral ligament suspension over a period of 5 years after surgery.

STUDY DESIGN

This was a secondary analysis of the 5-year follow-up of the SAVE-U trial. The SAVE-U trial was conducted in 4 Dutch hospitals. A total of 208 women with uterine prolapse stage ≥2 were randomized to sacrospinous hysteropexy or vaginal hysterectomy with uterosacral ligament suspension. For the current analysis, available annual 5-year follow-up data of 207 women were analyzed. Without missing values this analysis would have included 1035 measurements in total over the 5-year follow-up. Recurrences were analyzed as "events" using generalized linear mixed models because recurrences of anatomic failure and bothersome vaginal bulge symptoms fluctuated over time. The primary outcome was the composite outcome of failure defined as prolapse beyond the hymen, bothersome bulge symptoms, repeated surgery, or pessary use for recurrent prolapse. Secondary outcome measures were bothersome vaginal bulge symptoms, overall anatomic failure (Pelvic Organ Prolapse Quantification stage ≥2 in any compartment), apical compartment recurrence (Pelvic Organ Prolapse Quantification stage ≥2), anterior compartment recurrence (Pelvic Organ Prolapse Quantification stage ≥2), and posterior compartment recurrence (Pelvic Organ Prolapse Quantification stage ≥2).

RESULTS

For the composite outcome of failure (164 events in 66 different women), statistically significant risk factors were: body mass index (odds ratio, 1.10 [per 1 kg/m²]; 95% confidence interval, 1.02-1.19; P=.02), smoking (odds ratio, 2.88; 95% confidence interval, 1.12-7.40; P=.03), and preoperative Pelvic Organ Prolapse Quantification point Ba (odds ratio, 1.23 [per 1 cm]; 95% confidence interval, 1.01-1.50; P=.04). When analyzing each surgical outcome measure separately, body mass index and Pelvic Organ Prolapse Quantification point Ba were risk factors for overall anatomic failure (462 events in 147 women; odds ratio, 1.15; 95% confidence interval, 1.07-1.25; P<.01 and odds ratio, 1.14; 95% confidence interval, 1.00-1.30; P=.05, respectively) and anterior compartment recurrence (385 events in 128 women; odds ratio, 1.11; 95% confidence interval, 1.02-1.22; P=.02 and odds ratio, 1.17; 95% confidence interval, 1.02-1.34; P=.02, respectively). Vaginal hysterectomy was a risk factor for posterior compartment recurrence when compared with sacrospinous hysteropexy (93 events in 40 women; odds ratio, 5.21; 95% confidence interval, 2.05-13.27; P<.01). Smoking was a risk factor for bothersome vaginal bulge symptoms (70 events in 41 women; odds ratio, 3.80; 95% confidence interval, 1.48-9.75; P=.01), and preoperative Pelvic Organ Prolapse Quantification stage 3 or 4 was significantly protective against bothersome bulge symptoms (odds ratio, 0.32; 95% confidence interval, 0.11-0.89; P=.03).

CONCLUSION

Body mass index, smoking, and Pelvic Organ Prolapse Quantification point Ba were statistically significant risk factors for the composite outcome of failure (prolapse beyond the hymen, bothersome bulge symptoms, repeated surgery, or pessary use for recurrent prolapse) in the period of 5 years after surgery.

Clinical and pelvic floor ultrasound characteristics of pelvic organ prolapse recurrence after transvaginal mesh pelvic reconstruction

Background

Recurrence of pelvic organ prolapse (POP) after transvaginal mesh (TVM) implantation pelvic floor reconstruction surgery remains an unresolved problem in clinical practice. In this retrospective observational study, clinical and pelvic floor ultrasound (PFUS) parameters were analyzed in order to identify high-risk factors of POP recurrence.

Methods

The clinical and PFUS data from September 2013 to November 2019 of patients who underwent TVM were retrospectively analyzed. The patients with prolapse recurrence on postoperative follow-up diagnosed by PFUS were selected as case group, the clinical and PFUS parameters of them were compared with the control group in which the patients had no sign of prolapse recurrence. Univariate and multivariate regression analyses were performed based on age, BMI, gravidity, parity, surgical history (non-POP hysterectomy and incontinence-or-POP surgery), preoperative POP stage, follow-up in years, levator avulsion and hiatal area (HA) on Valsalva.

Results

Altogether 102 patients entered the study and the median interval between PFUS and TVM surgery was 2.5 years. Univariate analysis showed that levator avulsion and HA were significantly different between case group and control; multivariate regression analysis showed that only HA was related to prolapse recurrence after TVM (OR = 1.202, 95% CI 1.100–1.313, P < 0.001). The area under the ROC curve was 0.775 (95% CI 0.684–0.867, P < 0.001).

Conclusions

Hiatal area on Valsalva was related to prolapse recurrence after TVM surgery and it is an important parameter for postoperative follow-up of TVM surgery.

The impact of levator ani muscle trauma and contraction on recurrence after prolapse surgery

Introduction and hypothesis

The objective was to explore the impact of levator ani muscle (LAM) trauma and pelvic floor contraction on symptoms and anatomy after pelvic organ prolapse (POP) surgery.

Methods

Prospective study including 200 women with symptomatic POP ≥ grade 2 examined 3 months prior to and 6 months after surgery. Prolapse in each compartment was graded using the Pelvic Organ Prolapse Quantification (POP-Q) system, and women answered yes/no to a question about bulge sensation. Pelvic floor muscle contraction was assessed with transperineal ultrasound measuring proportional change in levator hiatal anteroposterior diameter from rest to contraction. LAM trauma was diagnosed using tomographic ultrasound imaging. Statistical analysis was performed using multivariate logistic regression analysis.

Results

A total of 183 women (92%) completed the study. Anatomical recurrence (POP ≥ grade 2) was found in 76 women (42%), and a bulge sensation was reported by 35 (19%). Ninety-two women (50%) had LAM trauma, and this was associated with increased risk of anatomical recurrence (OR 2.1 (95% CI 1.1–4.1), p = 0.022), but not bulge sensation (OR 1.1 (95% CI 0.5–2.4), p = 0.809). We found a reduced risk of bulge sensation for women with absent to weak contraction compared with normal to strong contraction (OR 0.4 (95% CI 0.1–0.9), p = 0.031), but no difference in risk for POP ≥ 2 after surgery (OR 1.5 (95% CI 0.8–2.9), p = 0.223).

Conclusions

Levator ani muscle trauma was associated with increased risk of anatomical failure 6 months after POP surgery. Absent to weak pelvic floor muscle contraction was associated with reduced risk of bulge sensation after surgery.

Women’s Experiences with Compliance with Pelvic Floor Home Exercise Therapy and Lifestyle Changes for Pelvic Organ Prolapse Symptoms: A Qualitative Study

In this study, we aimed to investigate women’s experiences with compliance with prescribed pelvic floor muscle exercises (PFMEs) and lifestyle changes 6–12 months after completing an individual pelvic floor physiotherapy program. This study was targeted to understanding factors affecting adherence to PFMEs and lifestyle changes to deal with pelvic organ prolapse (POP) symptoms. We designed this research as a descriptive qualitative study. We conducted this study from December 2016 to September 2017 in Madrid, Spain. Twenty-six women with symptomatic POP selected using a purposive sampling method participated in six focus groups and three one-to-one semi-structured interviews. Three authors coded and inductively analyzed transcript contents with iterative theme development. A thematic analysis revealed three main themes: (1) symptoms change; (2) PFMEs and lifestyle changes performance; and (3) a health practitioner–patient relationship. Women identified as adherent reported improvement in physical symptoms and emotional and general state as a result of the new knowledge achieved. Fear also promoted compliance with performing PFMEs and adopting lifestyle changes. Likewise, PFMEs preference and routine, integration of PFMEs and lifestyle changes into activities of daily living, support guides, therapeutic alliance, individual supervision, follow-up, and feedback were also identified as adherence facilitators. One of the biggest barriers that we identified was responsibility. Compliance with prescribed PFMEs and lifestyle changes can be improved with effective individual, women-centered, and supervised physiotherapy programs reducing symptoms, including exercises aligned with women’s preferences that are easy to integrate in daily living, promoting knowledge and awareness of their condition, providing written or electronic guidelines, with routine follow-up visits offering both positive feedback and clear and consistent messages, and enhancing therapeutic alliance.

Postoperative Urinary Incontinence in Diabetic Patients Undergoing Pelvic Reconstructive Surgery

IMPORTANCE

Diabetes is an independent risk factor for urinary incontinence, and its impact on rates of postoperative incontinence after pelvic reconstructive surgery remains unexplored.

OBJECTIVE

The aim of the study was to compare the incidence of postoperative stress urinary incontinence (SUI), urgency urinary incontinence (UUI), and mixed urinary incontinence in patients with diabetes mellitus undergoing surgery for pelvic organ prolapse (POP) with or without SUI surgery.

STUDY DESIGN

This is a secondary analysis of a multicenter retrospective cohort study involving 10 diverse medical centers that identified a cohort of women with diabetes who had prolapse and/or anti-incontinence surgery. We compared rates of postoperative urinary incontinence among patients who had surgery for prolapse and incontinence versus surgery for prolapse only.

RESULTS

Three hundred five patients had surgery for prolapse and incontinence, 330 had surgery for prolapse only, and 189 had anti-incontinence surgery only. De novo UUI was higher among those who underwent surgery for POP and SUI compared with surgery for POP alone (26.4% vs 14.1%, P < 0.01). Rates of persistent SUI (21% vs 4.9%, P < 0.01) and mixed urinary incontinence (15.9% vs 2.7%, P < 0.01) were higher for those who underwent prolapse surgery alone versus prolapse and an incontinence procedure. No differences were seen in hemoglobin A1C levels between those who did and did not report postoperative UI.

CONCLUSIONS

We found that postoperative de novo UUI rates were high among patients with diabetes after pelvic reconstructive surgery, with the incidence being significantly higher for those who had surgery for prolapse and incontinence compared with surgery for prolapse only.

Predictors of Clinical Outcome in Women with Pelvic Organ Prolapse Who Underwent Transvaginal Mesh Reconstruction Surgery

Background and Objectives: To identify the predictors of clinical outcomes in women with pelvic organ prolapse (POP) who underwent transvaginal reconstruction surgery, especially with transobturator mesh fixation or sacrospinous mesh fixation. Materials and Methods: All women with POP who underwent transvaginal reconstruction surgery, especially with transobturator mesh fixation or sacrospinous mesh fixation, were reviewed. Results: Between January 2011 and May 2019, a total of 206 consecutive women were reviewed, including 68 women receiving POP reconstruction with transobturator mesh fixation and 138 women who underwent POP reconstruction with sacrospinous mesh fixation. The least experienced surgeon (hazard ratio = 804.6) and advanced stage of cystocele (hazard ratio = 8.80) were the predictors of POP recurrence, especially those women with stage 4 of cystocele. Young age (hazard ratio = 0.94) was a predictor for mesh extrusion, especially those women with age ≤67 years. Follow-up interval (odds ratio = 1.03, p = 0.02) was also an independent predictor of mesh extrusion. High maximum flow rate (Qmax, hazard ratio = 1.03) was the sole predictor of postoperative stress urinary incontinence, especially those women with Qmax ≥19.2 mL/s. Preoperative overactive bladder syndrome (hazard ratio = 3.22) were a predictor for postoperative overactive bladder syndrome. In addition, overactive bladder syndrome rate improved after surgery in the sacrospinous group (p = 0.0001). Voiding dysfunction rates improved after surgery in both sacrospinous and transobturator groups. Conclusions: Predictors of clinical outcome in women who underwent transvaginal POP mesh reconstruction are identified. The findings can serve as a guide for preoperative consultation of similar procedures.

Preoperative level II/III MRI measures predicting long-term prolapse recurrence after native tissue repair

INTRODUCTION AND HYPOTHESIS

To identify preoperative level II/III MRI measures associated with long-term recurrence after native tissue prolapse repair.

METHODS

Women who previously participated in pelvic floor research involving MRI prior to undergoing primary native tissue prolapse repair were recruited to return for repeat examination and MRI. Recurrence was defined by POP-Q (Ba/Bp > 0 or C > -4), repeat surgery, or pessary use. Preoperative MR images were used to perform five level II/III measurements including a new levator plate (LP) shape analysis at rest and maximal Valsalva. Principal component analysis (PCA) was used to evaluate LP shape variations. Principal component scores calculated for two independent shape variations were noted.

RESULTS

Thirty-five women were included with a mean follow-up of 13.2 ± 3.3 years. Nineteen (54%) were in the success group. There were no statistical differences between success versus recurrence groups in demographic, clinical, or surgical characteristics. Women with recurrence had a larger preoperative resting levator hiatus [median 6.4 cm (IQR 5.7, 7.1) vs. 5.8 cm (IQR 5.3, 6.3), p = 0.03]. This measure was associated with increased odds of recurrence (OR 8.2, CI 1.4-48.9, p = 0.02). Using PCA, preoperative LP shape PC1 scores were different between success and recurrence groups (p = 0.02), with a more dorsally oriented LP shape associated with recurrence.

CONCLUSIONS

Larger preoperative levator hiatus at rest and a more dorsally oriented levator plate shape were associated with prolapse recurrence at long-term follow-up. For every 1 cm increase in preoperative resting levator hiatus, the odds of long-term prolapse recurrence increases 8-fold.
