A total of 199 patients and 370 collecting systems were examined in total. Axial raw data and reconstructed coronal thin and thick MIP images with a slice thickness of 5 mm were evaluated by 2 independent radiologists blinded to the initial diagnosis. Renal collecting system, ureters, and bladder were included in radiological evaluation. Anatomically, the renal collecting system was separated into 7 regions. Filling and dilatation of collecting systems were evaluated via images at urogram phase by scoring. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; Filling in lower pole infundibulum (&lt;i&gt;p&lt;\/i&gt; = 0.006), distal ureter (&lt;i&gt;p&lt;\/i&gt; = 0.006); and highly dilated lower pole calyx (&lt;i&gt;p&lt;\/i&gt; = 0.020), pelvis (&lt;i&gt;p&lt;\/i&gt; = 0.006), and bladder (&lt;i&gt;p&lt;\/i&gt; &amp;#x3c; 0.001) were determined to be better in images in the prone position compared to the supine position. There were no statistical differences in other regions. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; Better contrast material filling is achieved in dilated or non-dilated lower pole collecting system, dilated renal pelvis, non-dilated distal ureter of kidney, and in the bladder only by imaging the urogram phase in the prone position compared to the supine position. Additionally, presence of dilatation is a factor that could adversely affect filling. Studies in the future may investigate the contribution of prone positioning to CT urogram with larger series comparing it with other methods and modalities.<\/jats:p>","DOI":"10.1159\/000490735","type":"journal-article","created":{"date-parts":[[2018,7,6]],"date-time":"2018-07-06T21:01:29Z","timestamp":1530910889000},"page":"167-174","source":"Crossref","is-referenced-by-count":3,"title":["Effect of Prone and Supine Positioning on Computed Tomography Urography Examination"],"prefix":"10.1159","volume":"101","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6649-3256","authenticated-orcid":false,"given":"Erdal","family":"Karava\u015f","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Safiye","family":"G\u00fcrel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aysu","family":"K\u0131yan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S\u0131dd\u0131ka","family":"Halicio\u011flu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emine","family":"Da\u011fistan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2018,7,6]]},"container-title":["Urologia Internationalis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/490735","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/490735","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T16:41:56Z","timestamp":1745426516000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000490735"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2018,8,22]]},"published-print":{"date-parts":[[2018,8,28]]}},"URL":"https:\/\/doi.org\/10.1159\/000490735","archive":["Portico"],"relation":{},"ISSN":["0042-1138","1423-0399"],"issn-type":[{"value":"0042-1138","type":"print"},{"value":"1423-0399","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018]]}}}
