Three antenatal pop-off mechanisms were identified: presence of an umbilical cord cyst (UCC), extravasation of urine into the intraperitoneal space (ascites) or perirenal subcapsular (urinoma), and megaureter/ureterocele. Cases that exhibited two different pop-off mechanisms, underwent vesicoamniotic shunt placement or had unclear information regarding shunt placement were excluded.

Following exclusions, 511 cases were included in the analysis. The identification of UCC (n = 39) was associated with early-onset megacystis (odds ratio (OR), 4.2 (95% CI, 1.9-9.1); P < 0.001), severe megacystis (OR 2.3 (95% CI, 1.1-5.0); P = 0.033), normal amniotic fluid index (AFI) (OR, 3.3 (95% CI, 1.3-8.2); P = 0.011) and additional associated anomaly (OR, 3.3 (95% CI, 1.7-6.4); P < 0.001), and thus with the highest prevalence of complex diagnosis (66%), primarily represented by anorectal malformation. Extravasation (n = 42) was associated with severe megacystis (OR, 2.4 (95% CI, 1.1-5.4); P = 0.030), abnormal AFI (OR, 2.8 (95% CI, 1.2-6.8); P = 0.022), the keyhole sign (OR, 2.5 (95% CI, 1.1-5.8); P = 0.033) and additional associated anomaly (OR, 2.1 (95% CI, 1.1-4.1); P = 0.026). Megaureter/ureterocele (n = 36) was associated with late-onset megacystis (OR, 4.0 (95% CI, 1.6-9.7); P = 0.003), a thickened bladder wall during pregnancy (OR, 6.6 (95% CI, 1.9-23.1); P = 0.003) and the lowest prevalence of additional associated anomaly (22%). Intrauterine fetal demise was most prevalent in fetuses with UCC (15%), while termination of pregnancy and non-survivors were most common in cases with extravasation (50% and 17%, respectively). The majority of fetuses with megacystis associated with megaureter/ureterocele were still alive during follow-up (72%) and the odds of survival were the highest for this group (OR, 2.7 (95% CI, 1.3-5.7); P = 0.010).</p><p><strong>Conclusions: </strong>Antenatal pop-off mechanisms may alleviate high intraluminal pressure wi","PeriodicalId":23454,"journal":{"name":"Ultrasound in Obstetrics & Gynecology","volume":" ","pages":"487-494"},"PeriodicalIF":6.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11961101/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143558092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

N-terminal pro B-type natriuretic peptide (NT-proBNP) is elevated in PE owing to the cardiovascular effects of this disease. This study aimed to identify the predictive performance of NT-proBNP to detect PE and placental complications within 1 week after assessment, and compare it with the predictive performance of the sFlt-1/PlGF ratio. High-sensitivity troponin T (hs-TnT) and uric acid were also evaluated.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This was a prospective nested case-control study conducted in five Spanish centers between March 2018 and December 2020, and comprised women with a singleton pregnancy and suspected PE between 24 + 0 and 41 + 0 weeks' gestation. We evaluated the ability of the sFlt-1/PlGF ratio, NT-proBNP, hs-TnT and uric acid to predict the development of any-onset (at any gestational age), early-onset (before 34 weeks) or term (at or after 37 weeks) PE within 1 week or 4 weeks after assessment. Predictive performance was assessed by estimating negative predictive values, positive predictive values, sensitivity, specificity and areas under the receiver-operating-characteristics curves (AUCs) for these biomarkers, with corresponding 95% CIs. We performed post-hoc exploratory analyses of associations between the sFlt-1/PlGF ratio, NT-proBNP, hs-TnT and uric acid in women who developed PE, as well as in women who developed complicated PE (PE plus fetal growth restriction, stillbirth or placental abruption) within 1 week and 4 weeks after assessment.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;A total of 323 women with suspected PE at or before 41 + 0 weeks were enrolled in the study, of whom seven were lost to follow-up. The final analysis included 316 eligible participants, with 424 samples. The overall incidence of PE was 23.4% (n = 74) and early-onset PE developed in 8.5% (n = 27) of cases. The sFlt-1/PlGF ratio and NT-proBNP exhibited similar abilities to predict early-onset PE within 1 week after assessment (AUC, 0.970 (95% CI, 0.932-1.000) and 0.971 (95% CI, 0.942-1.000), respectively). hs-TnT and uric acid demonstrated inferior predictive capability compared with the sFlt-1/PlGF ratio for the prediction of any-onset PE, early-onset PE and term PE within 1 week and 4 weeks after assessment. The optimal cut-off for NT-proBNP was 116 pg/mL. At this cut-off, NT-proBNP showed a sensitivity of 90.9% (95% CI, 70.8-98.9%) and a specificity of 94.3% (95% CI, 91.2-96.5%), with a positive predictive value of 5.7% (95% CI, 3.7-8.7%) and a negative predictive value of 99.9% (95% CI, 99.9-100%) in predicting early-onset PE within 1 week of assessment, which was comparable with that of the sFlt-1/PlGF ratio.
