RESUMO
The evaluation of labor is the clinical process by which variables are analyzed in order to determine whether the patient is in labor, which by definition includes regular uterine contractions that increase in frequency and intensity, associated with dilation cervical. This is done through the anamnesis and physical examination, specifically through the evaluation of contractions and vaginal examination, the latter is intended to specify the degree of dilation, cervical effacement that the patient presents and also allows to a certain degree, establish the presentation, attitude and variety of position in which the fetus is located. From this premise, it is proposed that vaginal examination, since it is operator dependent, is not an objective evaluation, therefore, there is a need to reach consensus on the evaluation, and in order to carry it out, evaluation with ultrasound is proposed, which has as a purpose to objectify the variety of position and presentation of the fetus. Due to the above, this article aims to capture the knowledge that is currently possessed about the uses and methodology that intrapartum ultrasound presents.

AIM: This study aimed to assess, for the first time, the dynamic morphometry of pelvic floor muscles (PFM) using three-dimensional transperineal ultrasound (3D-TPUS) and its progression at two-time points of gestation between women with and without gestational diabetes mellitus (GDM), and whether the PFM dysfunction is connected to GDM. METHODS: The study comprised 83 consecutive pregnant women with (n = 38) and without (n = 45) GDM screened at 24-30 and 38-40 weeks of gestation. 3D-TPUS and a mobility test were used to quantify PFM dynamic morphometry during maximum contraction and the Valsalva maneuver. RESULTS: When compared to the control group, GDM women had no significant variations in all levator hiatal dimensions at 24-30 weeks of gestation. Meanwhile, women with GDM experienced an increase in levator hiatal area (LHa) (p < 0.000) during PFM contraction and enlargement in LHa (p < 0.001) during Valsalva maneuver (p = 0.010) at 38-40 weeks of gestation. As a result, the mobility index among GDM women had a lower value (p = 0.000). The dynamic morphometry development of PFM in GDM women at two stages during pregnancy revealed a substantial decrease (p = 0.000) in all LHa dimensions of contraction, distension, and mobility. CONCLUSIONS: Using 3D-TPUS, we found that GDM women had a specific pattern of PFM functional changes in the third trimester of pregnancy. These initial findings revealed alterations in PFM functionality, such as decreased contractility, distensibility, or mobility. This dysfunctional PFM could contribute to the long-term development of pelvic floor dysfunction years after a GDM pregnancy.

INTRODUCTION: Although pelvic floor muscle (PFM) weakness can be associated with pelvic floor dysfunctions, knowledge about the relationship with sexual dysfunction is limited. AIM: The aim of this study was to evaluate the association between PFM strength and sexual function in postmenopausal women. METHODS: An analytical cross-sectional study was conducted on 226 sexually active heterosexual women aged 45-65 years with amenorrhea >12 months and without pelvic floor disorders. The Female Sexual Function Index (FSFI) was used for the evaluation of sexual function (total score ≤26.5 indicating sexual dysfunction). PFM strength was assessed by bidigital vaginal palpation using the modified Oxford scale (score 0-5) and was categorized into nonfunctional (scores 0-1, without contraction) and functional (scores 2-5, with contraction). Three-dimensional transperineal ultrasound was used to evaluate total urogenital hiatus area, transverse and anteroposterior diameters, and levator ani muscle thickness. MAIN OUTCOME MEASURE: The main outcome measure was to determine the relationship between sexual dysfunction and PFM strength. RESULTS: The participants were classified as functional PFM (n = 143) and nonfunctional PFM (n = 83). There were no differences between groups in clinical and anthropometric parameters. A higher percentage of menopausal hormone therapy users was observed in the group with functional PFM (39.2%) compared to the nonfunctional group (24.1%; P = .043). Women classified as functional PFM exhibited greater levator ani muscle thickness than those classified as nonfunctional (P = .049). Women with nonfunctional PFM had poorer sexual function in the desire (P = .005), arousal (P = .001), and orgasm (P = 0.006) domains and in total FSFI score (P = .006) compared to the functional group. There was a weak positive correlation of PFM strength with the desire (r = 0.35; P = .0003), arousal (r = 0.21; P = .013), and orgasm (r = 0.23; P = .033) domains and with total FSFI score (r = 0.28; P = .004). Ultrasonographic levator ani muscle thickness showed a weak positive correlation with PFM strength (r = 0.21; P = .046) and with the arousal domain (r = 0.23; P = .044). Risk analysis adjusted for age, time since menopause, parity, and body mass index showed a lower risk of sexual dysfunction in menopausal hormone therapy users (odds ratio = 0.26; 95% CI 0.11-0.60; P = .002) and in women with greater levator ani muscle thickness (odds ratio = 0.85; 95% CI 0.73-0.98; P = .025). CLINICAL IMPLICATIONS: The maintenance of PFM strength in the climacteric period is an important factor in postmenopausal women's sexual function. STRENGTH & LIMITATIONS: The main strength of the study is that, to our knowledge, this is the first study that evaluated the correlation of PFM strength and 3D transperineal ultrasound with different domains of sexual function in postmenopausal women. The main limitation is the cross-sectional design does not permit to establish a cause-effect relationship. CONCLUSION: Postmenopausal women with PFM dysfunction have poorer sexual function than women with functional PFM. Omodei MS, Marques Gomes Delmanto LR, Carvalho-Pessoa E, et al.

OBJECTIVES: To establish the prevalence of external (EAS) and internal (IAS) anal sphincter defects present 15-24 years after childbirth according to mode of delivery, and their association with development of fecal incontinence (FI). The study additionally aimed to compare the proportion of women with obstetric anal sphincter injuries (OASIS) reported at delivery with the proportion of women with sphincter defect detected on ultrasound 15-24 years later. METHODS: This was a cross-sectional study including 563 women who delivered their first child between 1990 and 1997. Women responded to a validated questionnaire (Pelvic Floor Distress Inventory) in 2013-2014, from which the proportion of women with FI was recorded. Information about OASIS was obtained from the National Birth Registry. Study participants underwent four-dimensional transperineal ultrasound examination. Defect of EAS or IAS of ≥ 30° in at least four of six slices on tomographic ultrasound was considered a significant defect and was recorded. Four study groups were defined based on mode of delivery of the first child. Women who had delivered only by Cesarean section (CS) constituted the CS group. Women in the normal vaginal delivery (NVD) group had NVD of their first child and subsequent deliveries could be NVD or CS. The forceps delivery (FD) group included women who had FD, NVD or CS after FD of their first born. The vacuum delivery (VD) group included women who had VD, NVD or CS after VD of their first born. Multiple logistic regression was used to calculate adjusted odds ratios (aORs) for comparison of prevalence of an EAS defect following different modes of delivery and to test its association with FI. Fisher's exact test was used to calculate crude odds ratios (ORs) for IAS defects. RESULTS: Defects of EAS and IAS were found after NVD (n = 201) in 10% and 1% of cases, respectively, after FD (n = 144) in 32% and 7% of cases and after VD (n = 120) in 15% and 4% of cases. No defects were found after CS (n = 98). FD was associated with increased risk of EAS defect compared with NVD (aOR = 3.6; 95% CI, 2.0-6.6) and VD (aOR = 3.0; 95% CI, 1.6-5.6) and with increased risk of IAS defect compared with NVD (OR = 7.4; 95% CI, 1.5-70.5). The difference between VD and NVD was not significant for EAS or IAS. FI was reported in 18% of women with an EAS defect, in 29% with an IAS defect and in 8% without a sphincter defect. EAS and IAS defects were associated with increased risk of FI (aOR = 2.5 (95% CI, 1.3-4.9) and OR = 4.2 (95% CI, 1.1-13.5), respectively). Of the ultrasonographic sphincter defects, 80% were not reported as OASIS at first or subsequent deliveries. CONCLUSIONS: Anal sphincter defects visualized on transperineal ultrasound 15-24 years after first delivery were associated with FD and development of FI. Ultrasound revealed a high proportion of sphincter defects that were not recorded as OASIS at delivery. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

BACKGROUND: The most common cause of anal sphincter injuries in women is vaginal birth. Endo-anal ultrasound is currently used for the diagnosis of anal sphincter defect. However, due to the inconvenience caused, it is not an applicable technique during the immediate post-partum. The aim of this study was to determine whether transperineal ultrasound in 3/4D is a useful diagnostic method for the assessment of anal sphincter during the immediate post-partum. MATERIAL AND METHODS: A prospective study was conducted on the vaginal deliveries performed between September 2012 and June 2013 in the Valme University Hospital (Seville). Obstetric and foetal parameters that could influence the onset of perineal tears were studied. The patients underwent a transperineal 3/4D ultrasound and a multislice study (48hours after birth). RESULTS: The study included 146 puerperal women. The sphincter complex was assessed in all of them during the immediate post-partum. External anal injuries were observed in 10.3% of the cases. In 8.2% of cases, the primary suture of the external anal sphincter was detected during ultrasound examination, and 2.1% of asymptomatic lesions were diagnosed only with post-partum ultrasound. None of the patients reported discomfort or pain. CONCLUSIONS: The 3-dimensional transperineal ultrasound is helpful in determining the primary repair of the anal sphincter during the immediate post-partum, with no discomfort for patients, as well as for establishing those early sphincter injuries that go unnoticed during vaginal delivery.

BACKGROUND: Rectocele is a herniation of the anterior wall of the rectal ampulla through a defect in the rectovaginal septum causing protrusion of the posterior vaginal wall. Common symptoms include symptoms of prolapse and obstructed defecation. AIMS: To describe subjective, anatomical and functional results of defect-specific rectocele repair. MATERIALS AND METHODS: This is an internal audit of 137 women who underwent defect-specific rectocele repair. Pre- and post-operative assessment included a standardised interview, clinical examination and 3D/4D transperineal ultrasound. Outcome measures were symptoms of obstructed defecation, recurrent prolapse symptoms, clinical posterior compartment recurrence and rectocele recurrence on ultrasound. RESULTS: At a mean follow-up of 1.4 years, 117 (85%) of women considered themselves cured or improved. Thirty-four (25%) complained of recurrent prolapse symptoms and 47 (34%) symptoms of obstructed defecation, a significant reduction (P < 0.0001). Clinical recurrence (Bp ≥ -1) was seen in 19 women (14%) and recurrence on ultrasound in 27 (20%). The mean depth of recurrence was 16.6 mm (10.3-25.1). We tested multiple potential predictors of recurrence, including age, BMI, vaginal parity, previous hysterectomy and/or prolapse surgery, follow-up time, pre-operative clinical and ultrasound findings. Only hiatal area on Valsalva (OR 0.95 for sonographic recurrence, P = 0.01) and enterocele (for clinical and sonographic recurrence, OR 4.03, P = 0.01 and OR 2.72, P = 0.02, respectively) reached significance. CONCLUSION: Defect-specific rectocele repair is effective both in restitution of normal anatomy and in resolving prolapse and obstructed defecation symptoms at a mean follow-up of 1.4 years.

OBJECTIVES: To determine the prevalence of evidence of residual obstetric anal sphincter injury, to evaluate its association with anal incontinence (AI) and to establish minimal diagnostic criteria for significant (residual) external anal sphincter (EAS) trauma. METHODS: This was a retrospective analysis of ultrasound volume datasets of 501 patients attending a tertiary urogynecological unit. All patients underwent a standardized interview including determination of St Mark's score for those presenting with AI. Tomographic ultrasound imaging (TUI) was used to evaluate the EAS and the internal anal sphincter (IAS). RESULTS: Among a total of 501 women, significant EAS and IAS defects were found in 88 and 59, respectively, and AI was reported by 69 (14%). Optimal prediction of AI was achieved using a model that included four abnormal slices of the EAS on TUI. IAS defects were found to be less likely to be associated with AI. In a multivariable model controlling for age and IAS trauma, the presence of at least four abnormal slices gave an 18-fold (95% CI, 9-36; P < 0.0001) increase in the likelihood of AI, compared with those with fewer than four abnormal slices. Using receiver-operating characteristics curve statistics, this model yielded an area under the curve of 0.86 (95% CI, 0.80-0.92). CONCLUSIONS: Both AI and significant EAS trauma are common in patients attending urogynecological units, and are strongly associated with each other. Abnormalities of the IAS seem to be less important in predicting AI. Our data support the practice of using, as a minimal criterion, defects present in four of the six slices on TUI for the diagnosis of significant EAS trauma.

OBJECTIVE: To determine the prevalence of obstetric anal sphincter injuries (OASIS) in a cohort of primiparous women and to evaluate their association with demographic, obstetric and ultrasound parameters. METHODS: This was a retrospective analysis of the ultrasound volume datasets of 320 primiparous women, acquired at 5 months postpartum. Tomographic ultrasound imaging (TUI) was used to evaluate the external anal sphincter (EAS). A significant EAS defect was diagnosed if a defect of > 30° was seen in four or more of six TUI slices bracketing the EAS. RESULTS: Significant EAS defects were found in 69 women (27.9% of those delivered vaginally). In nine of those a third-degree tear was diagnosed intrapartum and was sutured. In 60 women with significant defects there was no documentation of sphincter damage at birth, implying unidentified or occult defects (60/69, 87.0%). Among them, 29 had had a second-degree tear, two a first-degree tear and three an intact perineum. In 31 cases an episiotomy had been performed, with five extensions to a third-degree tear. On multivariate analysis only forceps delivery was significantly associated with OASIS. CONCLUSIONS: In this cohort of primiparous women we found OASIS in 27.9% of vaginally parous women, most of which had not been diagnosed in the delivery suite. There seems to be a need for better education of labor-ward staff in the recognition of OASIS. On the other hand, it is conceivable that some defects may be masked by intact tissue. The significance of such defects remains doubtful. Forceps delivery was the only identifiable risk factor.
