The Role of Gestational Diabetes Mellitus and Pelvic Floor 3D-Ultrasound Markers at the Second and Third Trimester of Pregnancy Predicting 6-18 Months Postpartum Urinary Incontinence: Preliminary Results From a Prospective Cohort

Background Gestational Diabetes Mellitus and long-term urinary incontinence (UI) have a severe impact on women's health. New methods to identify pregnant predictor risk factors of UI are needed. Our study investigated clinical and pelvic floor 3D-ultrasound markers in pregnant women at the second and third trimesters to predict 6-18 months postpartum UI. Methods This ongoing prospective cohort study included one hundred five nulliparous pregnant women with universal GDM screening and diagnosis, treated with nutritional and healthy lifestyle intervention. Pelvic floor 3DUltrasound was performed at the second and third trimesters of gestation. Clinical and pelvic floor 3DUltrasound biometry were collected. The ICIQ-SF and ISI questionnaires for UI were applied in the third trimester and 6-18 months postpartum. We performed univariate analysis (P<.20) to extract risk factors variables and multivariate logistic regression analysis (P<.05) to obtain the adjusted relative ratio for 6-18 months postpartum UI. Results In a preliminary result, a total of 93 participants concluded the follow-up. Using the variables obtained by the univariate analysis and after the adjustments for potential confounders, logistic regression analysis revealed that Gestational Diabetes Mellitus exposure was a strong and independent risk factor for 6-18 months postpartum UI (Adjusted RR 8.088; 95%CI 1.17-55.87; P:.034). In addition, higher hiatal area distension at rest from the second to the third trimester was negatively correlated with 6-18 months postpartum UI (Adjusted RR 0.966; 95%CI 0.93-0.99; P: .023). Conclusion Gestational Diabetes Mellitus was positively correlated with 6-18 months postpartum UI, and a higher hiatal area distension was negatively correlated with 6-18 months postpartum UI development.

Transperineal ultrasound to estimate the appropriate ring pessary size for women with pelvic organ prolapse

Introduction and hypothesis The objective was to predict the successful ring pessary size based on the levator hiatal area (HA). Methods This is a prospective case–control study. Women with symptomatic pelvic organ prolapse (POP) choosing pessary treatment were included. All women underwent an interview, clinical examination, and 3D/4D transperineal ultrasound (TPUS). The ring pessary size used in each trial and the reason for unsuccessful trials were recorded. In addition, levator hiatal area divided by ring pessary size (HARP ratio) was measured at rest, maximum contraction, and maximum Valsalva. The HARP ratios of successful and unsuccessful trials were compared, receiver operating characteristic curves in the prediction of successful trials were constructed, and the cut-off optimizing sensitivity and specificity was identified. Results A total of 162 women were assessed and 106 were included with 77 successful trials, 49 unsuccessful trials owing to dislodgment or failure to relieve POP symptoms, and 20 unsuccessful trials owing to pain/discomfort. Rest HARP ratio and Valsalva HARP ratio were significantly smaller in the successful trials versus dislodgment/failure to relieve POP symptoms trials (mean rest HARP ratio [SD]: 2.93 [0.59] vs 3.24 [0.67], p = 0.021; median Valsalva HARP ratio (IQR): 4.65 (1.56) vs 5.32 (2.08), p = 0.004). No significant difference was observed between pain/discomfort trials and successful trials. The best cut-off for the prediction of successful trials was Valsalva HARP ratio ≤ 5.00. Conclusions Unsuccessful fitting trials due to dislodgment/failure to relieve POP symptoms are associated with a small ring pessary with respect to the levator HA. A ring pessary that produces a Valsalva HARP ratio > 5.00 has a higher risk of dislodgment/failure to relieve POP symptoms.

The effect of pessary treatment on puborectalis muscle function

Introduction and hypothesis The objective was to assess if puborectalis muscle (PRM) function changes in women with pelvic organ prolapse (POP) undergoing pessary treatment. Methods This was a prospective cohort study of women with symptomatic POP choosing pessary treatment. An interview, clinical examination and 3D/4D transperineal ultrasound were performed at baseline and at 3-month follow-up. POP was assessed using the Pelvic Organ Prolapse Quantification system (POPQ). Parameters compared between baseline and follow-up were: hiatal area at rest (HArest), maximal contraction (HActx), and maximal Valsalva maneuver (HAVal), displacement in contraction (DISPL-ctx, i.e., relative difference between HArest and HActx), and displacement in Valsalva (DISPL-Val, i.e., relative difference between and HAVal and HArest). Parameters were compared in women with and those without complete avulsion. Results A total of 162 women were assessed and 34 were included. Mean age was 64 years (SD 11.4), and mean BMI 24 kg/m2 (SD 3.1). Thirty-one women had a cystocele, 8 a uterine prolapse, and 12 had a posterior compartment prolapse. Twenty-one women (61.8%) had a POP stage II, and 13 (38.2%) a POP stage III. Ring pessaries were most frequently used (97%). In the entire group a statistically significant increase in DISPL-ctx was observed (mean difference 2.1%, p = 0.017). In the no avulsion group HArest and DISPL-ctx increased significantly (mean difference 4.1%, p = 0.016 and 2.7%, p = 0.016 respectively) and the increase in DISPL-ctx was higher than in the avulsion group (mean difference 2.7% vs 0.2%, p = 0.056). Conclusion Our results show that PRM function changes in women with POP undergoing pessary treatment and suggest that such change occurs mainly in the absence of complete avulsion.

Role of three-dimensional ultrasound in females with obstructed defecation (in comparison with defecography)

Background Growing attention of pelvic floor disorders has led to development of new imaging techniques, with increasing importance of ultrasonography. The 3DUS technique is considered an accessible tool for imaging of the posterior pelvic compartment. The purpose of this study is to highlight the role of 3D ultrasound in evaluation of obstructed defecation in females and comparing the findings with defecography. Results Study included 30 females classified into two groups: (1) 20 patients (case group complaining of obstructed defecation); (2) ten females (control group-normal nulliparous females). All of them were subjected to defecography and 3D ultrasound during resting, squeezing, and straining. Detection rate of rectocele and intussusception with 3D ultrasound was lower than defecography. By US, significant statistical difference between patients and controls in all measurements of levator hiatus, IS, ES, and PRS thickness during straining (P value < 0.001). During straining, cut-off value of 20.75 cm2 for hiatal area gives sensitivity of 100% and specificity of 95% and using ARA, cut-off value of 105° gives sensitivity of 98% and specificity of 90% for differentiation between patients and controls. Conclusion Ultrasound can be considered a complementary test to defecography in investigation of patients with obstructed defecation. Ultrasound can diagnose levator muscle attenuation and avulsion, thickness of IS, ES, PRS, and distensibility of hiatal area.

Objective: To investigate the degree of cystocele and rectocele with a maximum of levator hiatal area (AHL) during Valsava. Methods: Secondary data analysis of 90 patients with uterine prolapse January 2012 to November 2013 in the clinic Uroginekologi RSCM, Jakarta. 3D/4D ultrasound measurement and pelvic organ prolapse system Quantification (POP-Q) stage I-IV cystocele and rectocelestage I-IV. All statistical analyses were analyzed using Stata 20 for Windows. Results: Significant difference cystocele stage I-II (n = 25) with stage III-IV (n = 65), the maximum AHL with a difference of 4.33 cm2 (p = 0.040). In rectocele stage I-II (n = 64) and stage III-IV (n = 26) of 3.85 cm2 (p = 0.130). AUC values for stage I-II and III-IV cystocele was 0.607 (IK95% from 0.467 to 0.738), and the ROC for rectocele was 0.603 (IK95% from 0.472 to 0.734). The ROC optimal cut point for cystocele stage I-II with III-IV with the highestsensitivity and specificity is 29 cm2 (0.523 sensitivity, specificity 0.520), the rectocele is 30 cm2 (0.538 sensitivity, specificity 0.584). Conclusion: There is a significant relationship between the degree of cystocele and area of the levator ani muscles when Valsava, but there is no relationship at rectocele. The value of maximum area under the curve (AUC) hiatal area of the levatorani muscle in distinguishing stage I-II and III-IV cystocele are relatively similar to rectocele stage I-II and III-IV. Optimal cut point hiatal area of the levatorani muscle in distinguishing stage I-II and III-IV cystoceleis 29 cm2, while for rectocele is 30 cm2 with sensitivity and specificity values were quite good.

Comparison of the Levator Hiatal Area

Objective: To determine the relationship of the levator hiatal area among nulliparous, primiparous, and multiparous women so that we can assess the prevalence of avulsion. Method: A cross-sectional study design was used by evaluating the transperineal ultrasound results of all nulliparous, primiparous, and multiparous women in the Obstetrics and Gynecology Clinic of Dr. Cipto Mangunkusumo hospital from May to December 2015. We analyzed the data through SPSS using one way ANOVA to compare the levator hiatal dimension among the groups of women during Valsava maneuver and at rest. Result: There were significant differences in levator hiatal area among nulliparous, primiparous, and multiparous women during Valsalva maneuver and at rest, which the mean (SD) was 22.26 (5.45) cm2 (p=0.028) and 10.70 (2.26) cm2 (p=0.012), respectively. Levator ani muscle avulsion was occurred in 1 out of 46 (2.2%) women from the primiparous and multiparous group. onclusion: There are significant differences in levator hiatal area during Valsalva and at rest among the groups.

Reproducibility in pelvic floor biometric parameters of nulliparous women assessed by translabial three-dimensional ultrasound using Omniview reformatting technique.

Aim: To assess the reproducibility of pelvic floor biometric parameters by translabial three-dimensional ultrasound compared with the OmniView® reformatting technique. Material and methods: We performed a cross-sectional study involving 47 nulliparous women without symptoms of pelvic floor dysfunction. The hiatal area and right pubovisceral muscle width measurements were performed in the axial plane using both 3D ultrasound in the rendering mode and OmniView® techniques. To determine the occurrence of standardized error between examiners and the two sonographic methods, the paired t-test was used. The intra- and inter-observer reliability and agreement were estimated by concordance correlation coefficient (CCC) and limits of agreement, respectively. Results: We did not observe significant statistical differences among both measurements performed by the first examiner, both examiners and both methods in the assessment of the hiatal area; however, the measurements of the right pubovisceral muscle were significantly lower using OmniView®. The intra-observer reliability was good in the evaluation of all pelvic floor parameters; however, the inter-observer reliability was good only to the 3D rendering mode (CCC=0.87). The intra-observer agreement was good in the assessment of all pelvic floor parameters; however, the inter-observer agreement was found to be good only when 3DUS in the rendering mode was used (<±15%). Conclusion: Both 3D ultrasound in the rendering mode and OmniView® reformatting techniques were concordant in the assessment of pelvic floor parameters; however, the 3D ultrasound rendering in the mode demonstrated better inter-observer reliability and agreement.
