However, catheterization of the right adrenal vein (RAV) is challenging due the small size and variable location. This study aims to explore the relationship between the RAV orifice and the right kidney contour (RKC) on fluoroscopy, thus evaluating the potential of use the RKC as an anatomic marker for localizing RAV. Imaging data of 107 PA patients with successful bilateral AVS were retrospectively analyzed. Based on the body mass index (BMI), all patients were divided into the Normal Group (BMI &lt; 24 kg\/m<jats:sup>2<\/jats:sup>), Overweight Group (24 kg\/m<jats:sup>2<\/jats:sup> \u2264 BMI &lt; 28 kg\/m<jats:sup>2<\/jats:sup>) and Obese Group (BMI \u2265 28 kg\/m<jats:sup>2<\/jats:sup>). At the anterior view, the height level of RAV orifice was determined relative to vertebral bodies and disks. The distance from the RAV orifice to the upper edge of RKC was measured manually. The RAV orifice height level was mainly distributed from vertebral T11 to T12 (90.6%), and tended to be higher in patients with a larger BMI. The mean distance from the RAV orifice to the upper edge of RKC was 13.9\u00b17.8mm, and had no difference among Normal group (n = 53, 14.1\u00b18.2mm), Overweight group (n = 39, 13.7\u00b18.0mm), and Obese group (n = 15, 13.9\u00b15.5mm) (<jats:italic>p<\/jats:italic> = 0.981). Based on these findings, the RKC might be used as a landmark for localizing RAV on fluoroscopy, which is conductive to narrow down the exploration range and increase the success rate of RAV catheterization.<\/jats:p>","DOI":"10.1371\/journal.pone.0263945","type":"journal-article","created":{"date-parts":[[2022,9,29]],"date-time":"2022-09-29T19:07:09Z","timestamp":1664478429000},"page":"e0263945","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":5,"title":["Use
