All adrenal veins were identified. We compared the preoperative, intraoperative, and postoperative data between patients with and without variant adrenal venous anatomy. We also explored the factors associated with venous variants.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We found variant venous anatomy in 62 of 303 adrenalectomies (20.5%). Compared with patients with normal anatomy, those with variant anatomy were associated with larger tumor size, larger adrenal veins, more adrenal medullary tumors, longer operation time, more estimated intraoperative blood loss, longer length of hospitalization, and more transfusion. Computed tomography (CT) images may improve the identification of venous anatomy. Tumor size and diagnosis of pheochromocytoma were independently related to variant venous anatomy, whereas sex, tumor size, and venous variant influenced hemorrhage. For pheochromocytoma with variant venous anatomy operated on by a single surgeon, robot\u2010assisted laparoscopic adrenalectomy was associated with shorter postoperative hospitalization.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Adrenal vein variants are associated with worse outcomes in adrenal tumors and an optimized surgery strategy should be applied to this group of patients.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jso.25364","type":"journal-article","created":{"date-parts":[[2019,1,30]],"date-time":"2019-01-30T11:00:16Z","timestamp":1548846016000},"page":"801-806","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Retrospective analysis of variant venous anatomy in 303 laparoscopic adrenalectomies and its clinical implications"],"prefix":"10.1002","volume":"119","author":[{"given":"Fukang","family":"Sun","sequence":"first","affiliation":[{"name":"Department of Urology Ruijin Hospital, Shanghai Jiao Tong University School of Medicine Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7781-3806","authenticated-orcid":false,"given":"Ran","family":"Zhuo","sequence":"additional","affiliation":[{"name":"Department of Urology Ruijin Hospital, Shanghai Jiao Tong University School of Medicine Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenming","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Urology Ruijin Hospital, Shanghai Jiao Tong University School of Medicine Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongchao","family":"He","sequence":"additional","affiliation":[{"name":"Department of Urology Ruijin Hospital, Shanghai Jiao Tong University School of Medicine Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Ye","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory for Endocrine Tumors Shanghai Clinical Center for Endocrine and Metabolic Diseases, Key Laboratory for Endocrine and Metabolic Diseases of Chinese Health Ministry, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine Shanghai China"},{"name":"Laboratory for Endocrine &amp;
