A vaginal evaluation of the cervix was made in 143 pregnant women who by means of ultrasonographic method were found to have low-lying placentas. In as many as 68 out of the 143 studied cases (47.5%), the low-lying placenta coincided with a shortening of the cervix about half its normal length or in both shortening and patency of the uterocervical canal, measuring up to 2 cm in diameter (39 cases). The statistical calculations indicate that a low-lying placenta can influence cervical behaviour and that it appears to be a risk factor of cervical incompetence.<\/jats:p>","DOI":"10.1159\/000298964","type":"journal-article","created":{"date-parts":[[2010,3,16]],"date-time":"2010-03-16T04:07:18Z","timestamp":1268712438000},"page":"6-13","source":"Crossref","is-referenced-by-count":0,"title":["Can a Low-Lying Placenta Be the Risk Factor of Cervical Incompetence?"],"prefix":"10.1159","author":[{"given":"Mieczysiaw","family":"Uszynski","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomasz","family":"Majczynski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Waldemar","family":"Uszynski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,3,15]]},"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000298964","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T06:36:00Z","timestamp":1777617360000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000298964"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,3,15]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000298964","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,3,15]]}}}
