However, the acceleration time was significantly prolonged in the twin pregnancy group compared with that in the singleton pregnancy group (83.7 \u00b1 24 vs. 59.8 \u00b1 12 ms, p &lt; 0.01). &lt;i&gt;Conclusion:&lt;\/i&gt; The current results imply that maternal renal arteries are more significantly affected by hemodynamic changes in twin pregnancy than in singleton pregnancy.<\/jats:p>","DOI":"10.1159\/000260331","type":"journal-article","created":{"date-parts":[[2009,11,24]],"date-time":"2009-11-24T08:38:55Z","timestamp":1259051935000},"page":"88-92","source":"Crossref","is-referenced-by-count":4,"title":["Hemodynamic Changes in Maternal Renal Arteries in Twin Pregnancy"],"prefix":"10.1159","volume":"69","author":[{"given":"Miwa","family":"Igarashi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hidehiko","family":"Miyake","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shunji","family":"Suzuki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,11,24]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1515%2Fjpme.1992.20.1.11"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1002%2Fjcu.10007"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ejogrb.2006.04.019"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016%2F0029-7844%2895%2900049-W"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1136%2Fbmj.38380.674340.E0"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.bpobgyn.2004.04.007"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007%2Fs003300101012"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1469-0705.2002.00638.x"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1097%2F00005053-197611000-00003"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1159%2F000009948"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1097%2F00006254-199403000-00027"}],"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/260331","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/260331","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T21:28:25Z","timestamp":1745443705000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000260331"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,11,24]]},"references-count":11,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2010,3,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000260331","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,11,24]]}}}
