A 3D finite element model of uterus support to evaluate mechanisms underlying uterine prolapse formation.

Uterine prolapse (UP) seriously affects the quality of life and physical and mental health of elderly women, which can easily be caused by ligament injury or intra-abdominal pressure (IAP) increasing. The objective of this manuscript was to study the influence of IAP and ligament injury on uterus and its surrounding ligaments using the finite element method. First, the three-dimensional (3D) models of retroverted uterus and its surrounding ligaments were established, and loads and constraints were set in ABAQUS software, then the stress and deformation of uterine ligaments and uterine displacement were calculated. The study found that the uterine displacement and the stress and deformation of the ligaments increased when IAP and ligament injury increased alone or simultaneously. Then, the stress and sensitivity of the ligaments to the changes of IAP or ligament injury were in the order of uterosacral ligament (USL), broad ligament (BL), cardinal ligament (CL) and round ligament (RL), while the deformation and sensitivity the changes of the ligaments were in the order of BL > RL > USL > CL. Moreover, the ligament injury had a greater influence on the uterus and uterine ligaments than IAP. The results of this study can provide guidance for optimization of surgical scheme of uterus prolapsed in clinic and exploration of pathogenesis.

Spontaneous transvaginal intestinal evisceration in case of long-standing uterine prolapse.

BACKGROUND: Transvaginal intestinal evisceration is an extremely rare surgical emergency with potentially fatal consequences. Only a few more than 100 cases with this pathology have been described in the literature. Aetiology is also unclear and multifactoral. CASE PRESENTATION: We report the case of an 80-year-old female who presented with sudden severe abdominal pain and spontaneous small bowel evisceration through the vagina along with associated high-grade uterine prolapse. The loops and their mesentery appeared edematous, thickened and dusky, but without apparent necrosis. An urgent laparotomy was performed with subsequent reduction of the prolapsed small bowel into the abdomen, hysterectomy, partial resection of the vagina and vaginal closure. Additional cholecystectomy was necessary because of the visible pathologic changes of the gallbladder. The postoperative period was uneventful. The unique feature of our case is that there was no trigger factor (trauma, constipation or a coughing episode that would increase the intra-abdominal pressure), provoking the vaginal rupture and intestinal evisceration through it in the context of pelvic floor weakness. CONCLUSIONS: Early detection and surgical management are crucial for preventing bowel ischemia and abdominal sepsis. If the eviscerated intestine is ischaemic and non-viable, this requires resection and anastomosis. The approach should be individualized and performed by a multidisciplinary team.

Uterine prolapse and associated factors among reproductive-age women in south-west Ethiopia: A community-based cross-sectional study.

BACKGROUND: Uterine prolapse is an important but neglected public health problem that causes maternal morbidity and mortality in women of reproductive age in low- and middle-income countries, including Ethiopia. However, little data are available concerning uterine prolapse in Ethiopia. The objective of this study was to assess the prevalence of and factors associated with uterine prolapse in women of reproductive age in Ethiopia. METHODS: A community-based cross-sectional study was conducted in Loma Woreda, Dawro, south-west Ethiopia, in November and December 2019. Four hundred and twenty-two randomly selected women of reproductive age participated in the study. Face-to-face interviews with a pre-structured questionnaire collected data, and diagnoses were made clinically. Epi Data v3.2.1 and SPSS v24 were used for data entry, processing, and analysis. Binary logistic regression was used to determine associations between dependent and independent variables. Variables with P-values less than 0.25 in bivariate logistic regression were further examined using multivariate logistic regression to investigate associations between the dependent variable and independent variables. RESULTS: The mean age of respondents was 35.4 ±7.994 years. The prevalence of symptomatic and anatomical uterine prolapse was 6.6% (28) and 5.9% (25), respectively. The prevalence of anatomical prolapse was used as a reference when determining associated factors. Age at first marriage (Adjusted Odd Ratio (AOR): 0.25, 95%CI 0.07, 0.89), place of delivery (AOR: 3.33, 95%CI 1.21, 9.13), birth attendant-assisted delivery (AOR 0.21; 95%CI 0.06, 0.71), and history of abortion (AOR: 2.94, 95%CI 1.08, 7.97) were found significantly and independently associated with the prevalence of uterine prolapse. CONCLUSION: Uterine prolapse is common in women of reproductive age. Age at first marriage, place of delivery, birth attendant-assisted delivery, and history of abortion were independent predictors of the prevalence of uterine prolapse. We recommend that the health system link primary health care to hospital-set for uterine prolapse treatment programs. Health institution delivery should be encouraged by the local government. Early marriage and unwanted pregnancy need to be prevented through appropriate strategies.

Dynamic magnetic resonance imaging evaluation before and after operation for pelvic organ prolapse.

PURPOSE: This study aimed to explore the value of dynamic magnetic resonance imaging (MRI) before and after operation for pelvic organ prolapse (POP). METHODS: Twenty-nine patients with POP (POP group) before and one month after surgery and 12 healthy women (control group) underwent static and dynamic MRI at rest and during straining (Valsalva maneuver). The preoperative MRI images of the POP and control groups were analyzed, and various measurements were recorded. Differences in measurements were compared between the POP and control groups; similarly, changes in measurements before and after operation were compared. RESULTS: In the POP group, MRI detected 29 anterior vaginal prolapses, 27 uterine prolapses, 1 rectoceles, and 14 pouch of Douglas hernias. In addition, 27 levator ani muscle defect and 15 pubocervical fascial defect cases were observed. The bladder-pubococcygeal line (B-PCL), uterus-pubococcygeal line (U-PCL), Douglas pouch-pubococcygeal line, the length of the hiatus, the descent of the levator plate, levator hiatus size, levator plate angle, iliococcygeus angle, and urethral inclination angle (UA) were larger in the POP group than in the control group. The pelvic organs' positions returned to normal postoperatively in 9 of 21 cases. The B-PCL, U-PCL, and UA were smaller post-surgery than pre-surgery. CONCLUSIONS: Static and dynamic MRI can comprehensively evaluate morphological and functional changes of the pelvic floor postoperatively.

Comparison of treatment outcomes for native tissue repair and sacrocolpopexy as apical suspension procedures at the time of hysterectomy for uterine prolapse.

Concomitant apical suspension should be performed at the time of hysterectomy for uterine prolapse to reduce the risk of recurrent prolapse. Native tissue repair (NTR) and sacrocolpopexy (SCP) are commonly used apical suspension procedures; however, it remains unclear which one is preferred. This study aimed to compare the treatment outcomes of NTR and SCP in terms of surgical failure, complication and reoperation rates. Surgical failure was defined as the presence of vaginal bulge symptoms, any prolapse beyond the hymen, or retreatment for prolapse. This retrospective cohort study included 523 patients who had undergone NTR (n = 272) or SCP (n = 251) along with hysterectomy for uterine prolapse and who had at least 4-month follow-up visits. During the median 3-year follow-up period, the surgical failure rate was higher in the NTR group (21.3% vs 6.4%, P < 0.01), with a low rate of retreatment in both groups. Overall complication rates were similar, but complications requiring surgical correction under anesthesia were more common in the SCP group (7.2% vs 0.4%, P < 0.01). As a result, the total reoperation rate was significantly higher in the SCP group (8.0% vs 2.6%, P = 0.02). Taken together, NTR may be a preferred option for apical suspension when hysterectomy is performed for uterine prolapse.

Single-cell transcriptome profiling of the vaginal wall in women with severe anterior vaginal prolapse.

Anterior vaginal prolapse (AVP) is the most common form of pelvic organ prolapse (POP) and has deleterious effects on women's health. Despite recent advances in AVP diagnosis and treatment, a cell atlas of the vaginal wall in AVP has not been constructed. Here, we employ single-cell RNA-seq to construct a transcriptomic atlas of 81,026 individual cells in the vaginal wall from AVP and control samples and identify 11 cell types. We reveal aberrant gene expression in diverse cell types in AVP. Extracellular matrix (ECM) dysregulation and immune reactions involvement are identified in both non-immune and immune cell types. In addition, we find that several transcription factors associated with ECM and immune regulation are activated in AVP. Furthermore, we reveal dysregulated cell-cell communication patterns in AVP. Taken together, this work provides a valuable resource for deciphering the cellular heterogeneity and the molecular mechanisms underlying severe AVP.

Uterus-Sparing Surgery: Outcomes of Transvaginal Uterosacral Ligament Hysteropexy.

STUDY OBJECTIVE: Recently, there has been a paradigm shift toward uterine conservation during the surgical management of pelvic organ prolapse (POP), specifically uterine prolapse. There are few reports on transvaginal uterosacral ligament hysteropexy (TULH). This study aimed to describe our surgical technique and outcomes. DESIGN: Retrospective review and description of surgical technique. Anatomic outcome has been reported using the POP quantification system. Complications were segregated. A comparison of parametric continuous variables was performed using paired t test. Categoric variables were evaluated using the Pearson χ2 test and the Fisher exact test. A p-value <.05 was considered significant. SETTING: Teaching hospital. PATIENTS: Forty patients who underwent TULH from 2009 to 2017. INTERVENTIONS: TULH. MEASUREMENTS AND MAIN RESULTS: A total of 40 patients met the inclusion criteria. Of these, 56.1% had preoperative stage 3 prolapse. The median operative time was 116 minutes. The mean estimated blood loss was 158.5 mL. Transient ureteral obstruction occurred in 2 patients. The mean follow-up time was 17.2 months, and all patients had significant improvement of prolapse (p <.001). There was also an improvement in urinary incontinence and bladder storage symptoms (p <.001). None of the patients were reoperated on for recurrent POP. CONCLUSION: TULH is an effective uterus-preserving surgical alternative for the treatment of uterovaginal prolapse and provides good apical support. It is also associated with a low short-term recurrence and incidence of reoperation. TULH is a viable option for suitable patients with uterovaginal prolapse who desire uterine conservation.

Role of acoustic radiation force-based elasticity imaging in endometrium pathologies.

BACKROUND: Ultrasonography is difficult to distinguish between endometrial pathologies and often requires curettage. ARFI (Acoustic Radiation Force-Based Elasticity Imaging) is a new ultrasonography elastography method. Using ARFI, it is possible to obtain information about the likelihood of the tissue benign or malignant. AIM: The aim of this study is to evaluate the contribution of ARFI to differentiate endometrial pathologies in hysterectomy specimens. SUBJECTS AND METHODS: Our study was prospectively, January-May 2017, performed in randomly 45 cases of 41-91 years of age (mean 58.3 years) who have decided to have hysterectomy. Hysterectomy was performed for uterine prolapse and endometrial hyperplasia in elderly patients and menorrhagia in young patients. Pathology results were compared with ARFI values and endometrial thickness. ANNOVA test was used for the comparison of ARFI values. RESULTS: Pathology revealed 14 cases of endometrial atrophy, 11 cases of proliferative phase, 10 cases of polyp, 6 cases of endometrial hyperplasia, and 4 cases of endometrium cancer. There is a statistically significant difference between mean ARFI values of endometrium, subendometrium, and myometrium of the groups (P < 0.05). There was a statistically significant difference between the mean endometrial thickness of the groups (P < 0.05). CONCLUSION: Endometrium ARFI contributes to the differential diagnosis of endometrial pathologies. Subendometrial and myometrial ARFI values decrease in polyps and increase in hyperplasia. Our study shows that the addition of subendometrium ARFI to gray-scale sonography before deciding on invasive procedures in endometrial pathologies may improve diagnostic accuracy. We concluded that further in vivo studies will establish the usefulness of this technique for preoperative diagnostic measures.

No mesh versus mesh in the treatment of anterior vaginal wall prolapse: prospective, randomised, controlled trial, long-term follow-up.

OBJECTIVES: To compare the efficacy and safety of anterior colporrhaphy (AC) versus transvaginal polypropylene mesh (PM) for the treatment of anterior vaginal wall prolapse (AVWP) at long-term follow-up. METHODS: Prospective and randomized controlled trial, 100 women with AVWP stage ≥ II assessed by the Pelvic Organ Prolapse Quantification System (POP-Q) underwent AC (control group) or PM insertion (mesh group). At baseline and at 60-month follow-up, safety profile, anatomical outcomes by POP-Q measurements and staging, subjective outcomes and quality of life (QoL) impact by ICIQ (SF and VV) and OAB-V8 questionnaires were assessed RESULTS: 76 women completed the study, 43 in Control versus 33 in Mesh group. Significant improvements were observed in all variables between the 2 times in each group (p < 0.0001), without differences between groups. Objective cure (POP-Q Ba ≤ - 2 and Ba ≤ - 1) occurred in 22 and 36 (51.2 and 83.7%) versus 23 and 31 (69.7 and 93.9%), p = 0.10 and 0.29; and subjective cure (VSS, no vaginal symptom) in 21 (48.8%) versus 17 (51.5%), p = 0.82, respectively, at 60-month follow-up. When adjusted for the other variables, Mesh group showed worse QoL impact due to subjective vaginal symptoms (odds ratio 3.99, CI 95% 1.13; 14.13). AVW asymptomatic mesh exposure occurred in 2 patients (6.06%) in the Mesh group. CONCLUSIONS: AC and PM provided good overall objective and subjective outcomes for a minimum 60-month follow-up. Vaginal and urinary symptoms improved post-operatively in both groups. Mesh group experienced four times more negative impact on QoL compared to Control at 60-month follow-up.

Risk of de novo posterior vaginal prolapse after anterior laparoscopic sacrocolpopexy: Evaluation at one year.

INTRODUCTION AND HYPOTHESIS: Treatment of anterior vaginal and/or apical prolapse by sacrocolpopexy is most often performed by systematic placement of two non-resorbable meshes, anterior and posterior, whether or not there is an associated posterior vaginal prolapse. We believe that isolated correction of an anterior vaginal and/or apical prolapse in the absence of posterior vaginal prolapse is not associated with a higher rate of de novo posterior vaginal prolapse. METHOD: A prospective, observational, monocenter study performed in the Gynecology unit of the Conception UHC in Marseille from May 2011 to October 2014. Patients over 18 years of age exhibiting an anterior vaginal and/or apical prolapse of stage ≥ 2 of the POP-Q classification resulting in functional impairment with alteration of the quality of life, without an associated posterior vaginal prolapse were included and underwent a laparoscopic anterior sacrocolpopexy (ASP). They were seen again in consultation one year from the intervention. Validated quality of life questionnaires were completed pre- and one year postoperatively. RESULTS: 50 patients were included. The rate of de novo posterior vaginal prolapse was 8/50 (16 %). At one year, there was a significant improvement in terms of the SPDI-20 and SPIQ-7 (p < 0.0001) questionnaire, without significant improvement in the quality of sexual function (PISQ-12 questionnaire) (p = 0.073). CONCLUSION: The risk of de novo posterior vaginal prolapse at one year is low when an ASP is carried out.

A Hypothesis Generating the Mechanical Systems Underlying Posterior Vaginal Prolapse Based on Observed Displacements by Dynamic Magnetic Resonance Imaging.

OBJECTIVE: The aim of this study was to analyze quantified displacements of the posterior vaginal wall (PVW) on dynamic magnetic resonance imaging (MRI), which may generate hypotheses for the detailed mechanisms that underlie the development of posterior vaginal prolapse. METHODS: Pelvic dynamic MRI scans were obtained for 12 women with normal vaginal structure (stage 0) and 62 women with 4 consecutive stages (1-4) of posterior vaginal prolapse. Structural locations (apex vagina, distal vagina, and mid-perineal body [PB]) and equidistant points along the PVW (points 4-6 were considered as midvagina) were identified, and PVW length, straight distance of PVW, levator ani parameters (levator hiatus length [LHL], levator hiatus width [LHW], levator plate angle, anorectal angle, and M line [ML]), urogenital hiatus, and prolapse diameter were measured at rest and maximal Valsalva, respectively. The displacement of these measurements was obtained. RESULTS: From stage 0 to 2, the variables LHL, LHW, levator plate angle, anorectal angle, and ML increased gradually, but midvagina, distal vagina, and mid-PB were the opposite. From stage 2 to 3, apex vagina, midvagina, distal vaginal, mid-PB, LHL, LHW, and ML raised rapidly and peaked at stage 3, then declined at stage 4. In addition, the correlation coefficients between each measurement from stage 2 to 3 were statistically higher than those from stage 0 to 2. CONCLUSIONS: Quantified displacements of the PVW and its supporting structure were shown on dynamic MRI, and the mechanical mechanisms were hypothesized regarding the interaction between pressure and the support force contributing to the deformation of the PVW and the supporting structures.

Renal failure caused by severe pelvic organ prolapse.

Pelvic organ prolapse (POP), the transvaginal descent of pelvic organs, can cause mild hydronephrosis but rarely leads to a deterioration in kidney function. We present a case of severe uterovaginal prolapse that caused bilateral ureteral obstruction and led to renal failure and urinary tract infection. During outpatient follow-up, kidney function had already been deteriorating, but POP was not recognised as a causal factor. A longer duration of ureteral obstruction can lead to irreversible kidney damage, and therefore, timely recognition and intervention is of essence. Even in complex cases with various causative factors for kidney injury, the presence of severe POP and kidney injury should prompt the clinician to exclude this cause.

Validation of noninvasive focal depth measurements to determine epithelial thickness of the vaginal wall.

OBJECTIVE: This study investigates whether noninvasive focal depth (FD) measurements correlate with vaginal wall epithelial thickness (ET). If FD accurately reflects ET of the vaginal wall, this would allow noninvasive longitudinal assessment of (newly developed) treatment modalities aiming to increase ET, without the need for invasive biopsies. METHODS: Fourteen women, median age 62 years (inter quartile ranges: 57-65), undergoing vaginal prolapse surgery because of anterior and/or posterior compartment pelvic organ prolapse were included. We used the CytoCam, a handheld video microscope based on incident dark field imaging, and performed FD measurements of the vaginal wall before surgery. Histology was performed on tissue that was removed during the surgical procedure, and ET was measured in stained sections. We compared ET with FD interindividually, and determined the expected linear correlation and agreement between the two measurements. RESULTS: Seventeen ET measurements (mean 125 µm ±â€Š38.7, range 48-181 µm) were compared with 17 FD measurements (mean 128 µm ±â€Š34.3, range 68-182 µm). The lineair correlation between the two measurements was strong (r = 0.902, P < 0.01). Bland-Altman analysis demonstrated a mean difference of 13.5 µm when comparing ET to FD. CONCLUSIONS: The results demonstrate good agreement between ET and FD measurements. We consider the mean difference demonstrated with Bland-Altman analysis acceptable for these measurements. This suggests that FD accurately reflects ET, which further supports the use of FD to measure ET of the vaginal wall. For a complete assessment of the vaginal wall, FD measurements are preferably combined with the assessment of vaginal angioarchitecture.

Comparison of measurement systems for posterior vaginal wall prolapse on magnetic resonance imaging.

INTRODUCTION AND HYPOTHESIS: A wide variety of reference lines and landmarks have been used in imaging studies to diagnose and quantify posterior vaginal wall prolapse without consensus. We sought to determine which is the best system to (1) identify posterior vaginal wall prolapse and its appropriate cutoff values and (2) assess the prolapse size. METHODS: This was a secondary analysis of sagittal maximal Valsalva dynamic MRI scans from 52 posterior-predominant prolapse cases and 60 comparable controls from ongoing research. All eight existing measurement lines and a new parameter, the exposed vaginal length, were measured. Expert opinions were used to score the prolapse sizes. Simple linear regressions, effect sizes, area under the curve, and classification and regression tree analyses were used to compare these reference systems and determine cutoff values. Linear and ordinal logistic regressions were used to assess the effectiveness of the prolapse size. RESULTS: Among existing parameters, "the perineal line-internal pubis," a reference line from the inside of the pubic symphysis to the front tip of the perineal body (cutoff value 0.9 cm), had the largest effect size (1.61), showed the highest sensitivity and specificity to discriminate prolapse with area under the curve (0.91), and explained the most variation (68%) in prolapse size scores. The exposed vaginal length (cutoff value 2.9) outperformed all the existing lines, with the largest effect size (2.09), area under the curve (0.95), and R-squared value (0.77). CONCLUSIONS: The exposed vaginal length performs slightly better than the best of the existing systems, for both diagnosing and quantifying posterior prolapse size. Performance characteristics and evidence-based cutoffs might be useful in clinical practice.

Perioperative changes in superficial pelvic organ prolapse quantification system measurements after prolapse surgery.

OBJECTIVES: To evaluate the values of perineal body (PB) and genital hiatus (GH) before and after posterior repair. We also evaluated the introital surface area (ISA)-a sum of transverse and longitudinal GH measurements. METHODS: This secondary analysis of a prospective case series included 94 women undergoing posterior vaginal prolapse surgery at a consultant urogynecology clinic between October 3, 2011, and October 2, 2014. Patients were examined in clinic using the pelvic organ prolapse quantification system with Valsalva maneuver, and in theatre pre- and postoperatively with traction. RESULTS: Immediately postoperatively, a statistically significant change (all P<0.001) was noted for GH (mean difference -0.59 cm), PB (-0.56 cm), and ISA (-0.87 cm) compared with preoperative measurement. This effect was maintained for GH (-0.42 cm) and PB (-0.40 cm) at 2 months' follow-up (both P<0.001), and for PB alone (-0.43 cm; P=0.04) at 8 months. ISA had a moderate correlation with GH (r=0.55). CONCLUSIONS: Posterior repair significantly improved PB length at months 2 and 8, and GH length at month 2. ISA did not correlate with prolapse stage. Changes in GH were not maintained beyond postoperative month 2.

Metastatic Acinic Cell Carcinoma to the Vagina: A First Reported Case.

This is a case of a 62-year-old woman with a remote history of acinic cell carcinoma of the parotid gland, who presented with a palpable vaginal mass, anterior vaginal wall prolapse, and stress urinary incontinence. A 2 cm firm mobile mass on the anterior vaginal wall was found on clinical examination. A computed tomographic scan revealed a mass between the vaginal vault and bladder that was eventually surgically excised. The histology, supported by the immunohistochemistry, revealed metastatic acinic cell carcinoma to the vagina after 37 years of her initial diagnosis. This is the first reported case in the literature to occur in the vagina.

Total vaginal length: Does it matter for assessing uterine prolapse?

INTRODUCTION AND HYPOTHESIS: Using the International Continence Society Pelvic Organ Prolapse Quantification (ICS POP-Q) system, uterine prolapse staging requires measurement of total vaginal length (TVL). The aim of this study was to determine whether TVT is a confounder of the relationship between uterine descent and POP symptoms. METHODS: This is a retrospective study on 721 patients seen in a tertiary urogynaecological unit. All patients had undergone a standardised, in-house, physician-led questionnaire and digital POP-Q examination. Patients with a history of hysterectomy or with a dominant prolapse in the anterior ± posterior compartment were excluded from analysis, leaving 393 complete data sets for analysis. Association between prolapse symptoms (lump/drag) and station of cervix (i.e. C) were tested. Age, body mass index (BMI), menospausal status and vaginal parity were tested as potential confounders. Variables that were significant on binary logistic regression (P < 0.05) were included in a model for receiver operting characteristic (ROC) statistical analysis. This was repeated after adding TVL to the model. Likelihood ratio test was performed to compare models. RESULTS: On binary logistic regression, prolapse symptoms were significantly associated with C, menopausal status and TVL (all P < 0.03). ROC analysis yielded an area under the curve (AUC) of 0.75 with menopausal status and C in the model. Adding TVL yielded an AUC of 0.773. The difference is statistically significant on the likelihood ratio test (P < 0.001). CONCLUSIONS: Adding TVL improved the performance of cervical station in predicting prolapse symptoms, validating the practice of using TVL in staging uterine prolapse.

Risk factors for coexistence of cervical elongation in uterine prolapse.

OBJECTIVE: To identify factors predicting cervical elongation in women with uterine prolapse. STUDY DESIGN: The medical records of women with uterine prolapse who underwent vaginal hysterectomy were reviewed. Multivariable logistic regression analysis was performed to identify predictors of cervical elongation. RESULTS: Of 295 women with uterine prolapse, 136 (46.1%) patients had cervical elongation, according to Berger et al. Classification (i.e., cervical length >3.38 cm and/or cervix-to-corpus lengths ratio >0.79). Multivariable analysis revealed that lower parity (odds ratio = 0.85, 95% confidence interval [CI] = 0.73 to 0.99, P = 0.04) and advanced stage of uterine prolapse (odds ratio = 1.97, 95% CI = 1.35-2.88, P < 0.001) were predictors for cervical elongation. Based on a receiver operating characteristic curve (ROC) analysis, the following optimum cut-off values were determined for cervical elongation: (1) parity ≤3, ROC area = 0.60 (95% CI = 0.53 to 0.66); (2) stage of uterine prolapse ≥3, ROC area = 0.63 (95% CI = 0.56 to 0.69). Thus, the predicted logit(p) for a given parity (a) and stage of uterine prolapse (b) can be denoted by logit(p) = -1.26 - 0.16 x a + 0.68 x b. The optimum cut-off values of logit(p) ≥-0.18 to predict cervical elongation were determined using ROC analysis (area = 0.66, 95% CI = 0.59 to 0.73). For women with parity ≤6, we can use either (1) stage 2 uterine prolapse and parity ≤1, or (2) ≥ stage 3 uterine prolapse as criteria to predict cervical elongation. CONCLUSIONS: Lower parity and advanced stage of uterine prolapse are predictors of cervical elongation in women with uterine prolapse. Thus, stage of uterine prolapse ≥3 or logit(p) ≥-0.18 may be useful for predicting cervical elongation.
