This study was conducted to observe CL changes preceding spontaneous onset of labour, by serial transvaginal sonography (TVS) and transabdominal sonography (TAS), in nulliparous Indian women near term.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n Only nulliparous women with a singleton foetus in cephalic presentation and who confirmed their gestational age were recruited. Sonographic CL measurements were taken at weekly intervals from 36 wk gestation onwards by a single ultrasonologist. Transabdominal and transvaginal measurements were undertaken using the suitable transducer probes with the women in the supine position.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n A total of 104 women with spontaneous onset of labour were evaluated. There was substantial variation in CL measurements, both by TVS and by TAS, from 36 to 40 wk gestation, although the two sets of measurements correlated closely. Mean CL changed significantly over the last three weeks before delivery. However, only one-third of the women showed CL change of >5 mm per week in the last three weeks. There was poor correlation between gestational age at delivery and the last measured CL, either by TVS or TAS. Length >3.1 mm, measured by TVS at 38 wk gestation, predicted post-dated pregnancy to a limited extent.<\/jats:p>\n <\/jats:sec>\n \n Interpretation & conclusions:<\/jats:title>\n Inter-individual variations in CL and in CL changes were large. Thus, it was not practical to predict spontaneous onset of labour by sonographic CL measurement near term. Post-dated pregnancy may be predicted with limited success. Further studies should explore other parameters, in addition to CL.<\/jats:p>\n <\/jats:sec>","DOI":"10.4103\/ijmr.ijmr_881_15","type":"journal-article","created":{"date-parts":[[2024,12,19]],"date-time":"2024-12-19T19:25:01Z","timestamp":1734636301000},"page":"498-504","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":5,"title":["Cervical length measurement in nulliparous women at term by ultrasound & its relationship to spontaneous onset of labour"],"prefix":"10.25259","volume":"146","author":[{"given":"Joydev","family":"Mukherji","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Avishek","family":"Bhadra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suhas Kumar","family":"Ghosh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Avijit","family":"Hazra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monika","family":"Anant","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Subir Kumar","family":"Bhattacharya","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bibekananda","family":"Das","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shabnam","family":"Banu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10894","reference":[{"key":"R1-9-20241212","doi-asserted-by":"crossref","first-page":"2533","DOI":"10.1016\/j.ultrasmedbio.2015.04.022","article-title":"Development of an ultrasonic method to detect cervical remodeling in vivo in full-term pregnant women","volume":"41","author":"McFarlin","year":"2015","journal-title":"Ultrasound Med Biol"},{"key":"R3-9-20241212","doi-asserted-by":"crossref","first-page":"468","DOI":"10.1002\/uog.13411","article-title":"Successful induction of labor: Prediction by preinduction cervical length, angle of progression and cervical elastography","volume":"44","author":"Pereira","year":"2014","journal-title":"Ultrasound Obstet Gynecol"},{"key":"R4-9-20241212","doi-asserted-by":"crossref","first-page":"108","DOI":"10.1016\/S0002-9378(00)70498-4","article-title":"Comparison of the bishop score, ultrasonographically measured cervical length, and fetal fibronectin assay in predicting time until delivery and type of delivery at term","volume":"182","author":"Rozenberg","year":"2000","journal-title":"Am J Obstet Gynecol"},{"key":"R5-9-20241212","doi-asserted-by":"crossref","first-page":"35","DOI":"10.1055\/s-2004-837268","article-title":"Prediction of spontaneous onset of labor at term: The role of cervical length measurement and funneling of internal cervical os detected by transvaginal ultrasonography","volume":"22","author":"Bayramoglu","year":"2005","journal-title":"Am J Perinatol"},{"key":"R6-9-20241212","doi-asserted-by":"crossref","first-page":"598","DOI":"10.1002\/uog.913","article-title":"Ultrasound examination at 37 weeks\u2019 gestation in the prediction of pregnancy outcome: The value of cervical assessment","volume":"22","author":"Ramanathan","year":"2003","journal-title":"Ultrasound Obstet Gynecol"},{"key":"R7-9-20241212","doi-asserted-by":"crossref","first-page":"652","DOI":"10.1002\/uog.5291","article-title":"Sonographic longitudinal cervical length measurements in nulliparous women at term: Prediction of spontaneous onset of labor","volume":"32","author":"Meijer-Hoogeveen","year":"2008","journal-title":"Ultrasound Obstet Gynecol"},{"key":"R8-9-20241212","doi-asserted-by":"crossref","first-page":"308","DOI":"10.1002\/uog.13407","article-title":"Cervical length in late second and third trimesters: A mixture model for predicting delivery","volume":"45","author":"Souka","year":"2015","journal-title":"Ultrasound Obstet Gynecol"},{"key":"R9-9-20241212","doi-asserted-by":"crossref","first-page":"292","DOI":"10.1046\/j.1469-0705.2000.00094.x","article-title":"Cervical assessment at the routine 23-weeks\u2019 scan: Problems with transabdominal sonography","volume":"15","author":"To","year":"2000","journal-title":"Ultrasound Obstet Gynecol"},{"key":"R10-9-20241212","doi-asserted-by":"crossref","first-page":"567","DOI":"10.1056\/NEJM199602293340904","article-title":"The length of the cervix and the risk of spontaneous premature delivery.
