Fetuses with pelviectasis were identified at later gestational weeks. Postnatal outcomes were followed, and the need for surgery was questioned in third trimester fetuses with values above 7\u2009mm. The diagnostic value of fetal renal pelvis anteroposterior diameter at 11\u201314\u2009weeks of gestation was investigated to determine fetal pelviectasis in advanced gestation and postnatal outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Fetal renal pelvis anteroposterior diameter values above 2\u2009mm predicted second and third trimester fetal renal pelviectasis with a sensitivity of 42.1%, specificity of 85.4%. Postnatal surgical intervention was required in four fetuses. Two fetuses with third trimester RPAPD values of 9\u2009mm underwent stent implantation, one fetus with an RPAPD of 19\u2009mm underwent right partial upper pole nephrectomy, and one fetus with an RPAPD of 15\u2009mm underwent stent implantation twice. Because of the very small number of surgical events and the heterogeneity of the procedures, this outcome was evaluated descriptively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>First trimester fetal renal pelvis anteroposterior diameter measurement appears feasible during routine ultrasound examination and shows a significant but limited association with pelviectasis in later gestation. Although the &gt;\u20092\u2009mm threshold demonstrated relatively low sensitivity, its acceptable specificity suggests that this parameter may provide preliminary evidence for future studies evaluating early fetal urinary tract assessment. However, no definitive conclusion can be drawn regarding postnatal surgery because of the very small number of surgical events.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/jcu.70381","type":"journal-article","created":{"date-parts":[[2026,8,20]],"date-time":"2026-08-20T03:39:33Z","timestamp":1787197173000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["First Trimester Fetal Renal Pelvis Diameter Cut\u2010Off Values for Predicting Fetal Pelviectasis in Advanced Gestation"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8760-3781","authenticated-orcid":false,"given":"Ayse Ceren","family":"Duymu\u015f","sequence":"first","affiliation":[{"name":"Selcuk University Faculty of Medicine  Konya Turkey"},{"name":"Usak Education and Research Hospital  Usak Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9632-5093","authenticated-orcid":false,"given":"Nizamettin","family":"Bozbay","sequence":"additional","affiliation":[{"name":"Selcuk University Faculty of Medicine  Konya Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-1209-3803","authenticated-orcid":false,"given":"\u015eeyma","family":"K\u0131l\u0131\u00e7","sequence":"additional","affiliation":[{"name":"Selcuk University Faculty of Medicine  Konya Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-7021-7120","authenticated-orcid":false,"given":"Feyza","family":"Sava\u015f","sequence":"additional","affiliation":[{"name":"Selcuk University Faculty of Medicine  Konya Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1975-6687","authenticated-orcid":false,"given":"\u00d6zlem Polat","family":"Bozbay","sequence":"additional","affiliation":[{"name":"Konya City Hospital  Konya Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6399-0166","authenticated-orcid":false,"given":"Aybike","family":"Pekin","sequence":"additional","affiliation":[{"name":"Selcuk University Faculty of Medicine  Konya Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,19]]},"reference":[{"issue":"3","key":"e_1_2_12_2_1","doi-asserted-by":"crossref","first-page":"247","DOI":"10.1002\/uog.12364","article-title":"Meta\u2010Analysis of Second\u2010Trimester Markers for Trisomy 21","volume":"41","author":"Agathokleous M.","year":"2013","journal-title":"Ultrasound in Obstetrics & Gynecology"},{"issue":"4","key":"e_1_2_12_3_1","doi-asserted-by":"crossref","first-page":"334","DOI":"10.1016\/j.jpurol.2019.03.027","article-title":"Significance of Third Trimester Ultrasound in Detecting Congenital Abnormalities of Kidney and Urinary Tract\u2014A Prospective Study","volume":"15","author":"Arora M.","year":"2019","journal-title":"Journal of Pediatric Urology"},{"key":"e_1_2_12_4_1","doi-asserted-by":"crossref","first-page":"419","DOI":"10.1007\/s00330-006-0307-1","article-title":"Evolution of Fetal Ultrasonography","volume":"17","author":"Avni F.
