Fetal anomalies associated with nonrenal causes of abnormal amniotic fluid volume were excluded. The vcRA-PI was calculated by dividing the RA-PI by the renal volume. The RA-PI was adjusted for GA, to obtain the GA-adjusted RA-PI. The uncorrected, GA-adjusted, and the vcRA-PI were related to the amniotic fluid level using nonparametric tests and receiver operating characteristic (ROC) curve analyses. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; 146 examinations from 59 pregnancies were reviewed. Of these, 16 had oligo- and 15 had polyhydramnios. A higher vcRA-PI was associated with oligohydramnios (OR 2.54, 95% CI 1.67\u20133.86, &lt;i&gt;p&lt;\/i&gt; &amp;#x3c; 0.001), while the uncorrected RA-PI and GA-adjusted RA-PI were not able to predict oligohydramnios. ROC curve analysis showed a high predictive accuracy of the vcRA-PI for oligohydramnios (AUC 0.84, 95% CI 0.72\u20130.94). On the other hand, the uncorrected RA-PI and GA-adjusted RA-PI significantly predicted polyhydramnios (&lt;i&gt;p&lt;\/i&gt; = 0.04 and 0.02, respectively), while the vcRA-PI did not. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; The vcRA-PI is superior to the uncorrected and the GA-adjusted RA-PI in predicting oligohydramnios.<\/jats:p>","DOI":"10.1159\/000491749","type":"journal-article","created":{"date-parts":[[2018,10,10]],"date-time":"2018-10-10T17:01:23Z","timestamp":1539190883000},"page":"97-102","source":"Crossref","is-referenced-by-count":7,"title":["The Relationship between the Fetal Volume-Corrected Renal Artery Pulsatility Index and Amniotic Fluid Volume"],"prefix":"10.1159","volume":"46","author":[{"given":"Viola","family":"Seravalli","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0189-8265","authenticated-orcid":false,"given":"Jena\u00a0L.","family":"Miller","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dana","family":"Block-Abraham","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cyrethia","family":"McShane","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Millard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmet","family":"Baschat","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2018,10,9]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1479-828X.1998.tb02995.x"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(92)91734-R"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1111\/jog.12601"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijgo.2015.05.010"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-3782(96)01798-7"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(95)90276-7"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-0705.2000.00121.x"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1002\/uog.976"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.148.1.6344137"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-0705.2001.00493.x"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.1973.tb16049.x"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejrad.2017.09.017"}],"container-title":["Fetal Diagnosis and Therapy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/491749","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/491749","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T12:48:38Z","timestamp":1745412518000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000491749"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,10,9]]},"references-count":12,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2019,8,16]]},"published-print":{"date-parts":[[2019,8,22]]}},"URL":"https:\/\/doi.org\/10.1159\/000491749","archive":["Portico"],"relation":{},"ISSN":["1015-3837","1421-9964"],"issn-type":[{"value":"1015-3837","type":"print"},{"value":"1421-9964","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,10,9]]}}}
