The shape was determined by transvaginal ultrasonography. Ultrasonographic evaluation of the morphological status of the cervix was performed in 57 randomly selected subjects between 16-24 weeks of pregnancy who had no sign or symptom of uterine contraction and no cervical dilatation. Ultrasonographically, the cervix, at the level of internal os was classified into 3 types: convex, flat and concave. Cervical length was measured from the internal to the external os. Subjects were monitored with a tocodynamometer to indicate the presence of uterine contraction. If contraction occurred once every 10-15 minutes before 33 weeks of gestation, it was considered as threatened preterm labor. The Chi-square test, Student's t-test and Anova were used for statistical analysis. Among the 57 subjects, 25 women showed a convex type of cervix, 17 women showed a flat type, and 15 women showed a concave type. Twenty seven (47.4%) women developed threatened preterm labor (7 with convex, 10 with flat and 10 with concave type). Twenty two women (38.6%) developed premature cervical dilatation (2 with convex, 7 with flat and 13 with concave type). Compared to the convex type, the concave and the flat type of cervix had a greater incidence of threatened preterm labor (p<0.05 for both types) and premature cervical dilatation (p<0.001 and p<0.05 for concave and flat type, respectively). The concave and flat types showed a positive predictive value of 86.7% and 41.2%, respectively, for premature cervical dilatation. Our results suggest that threatened preterm labor can be assessed in early pregnancy by ultrasonographic determination of the morphological shape of the cervix.","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球医学会"},{"subitem_1522300295150":"en","subitem_1522300316516":"Ryukyu Medical Association"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"1346888X"},{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0289-1530"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN10369445"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球医学会誌 = Ryukyu Medical Journal"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1997","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicPageEnd":"36","bibliographicPageStart":"31","bibliographicVolumeNumber":"17"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"v17p31.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2016064/files/v17p31.pdf"},"version_id":"bc9135c5-a6a6-4251-bfc9-221a3bc828d6"}]},"item_title":"[原著］Risk assessment of threatened preterm labor and prediction of premature cervical dilatation from the ultrasonographically determined morphological shape of the cervix","item_type_id":"15","owner":"1","path":["1642838209529","1642838412624"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-07-02"},"publish_date":"2010-07-02","publish_status":"0","recid":"2016064","relation_version_is_last":true,"title":["[原著］Risk assessment of threatened preterm labor and prediction of premature cervical dilatation from the ultrasonographically determined morphological shape of the cervix"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T07:49:38.016739+00:00"}
