Med."],"abstract":"<jats:p>Renal artery aneurysm and renal vein aneurysm are rare vascular lesions, and their coexistence within the same kidney poses considerable diagnostic and surgical challenges. We report a 51-year-old woman presenting with recurrent left flank and back pain. Computed tomography angiography demonstrated a 2.1-cm upper-pole renal artery aneurysm arising from a terminal intrarenal arterial branch and a 3.0-cm renal vein aneurysm arising from a large intrarenal venous tributary in the mid-pole renal sinus. Nephrectomy had been recommended at another institution because of the anatomical complexity, but the patient strongly wished to preserve the affected kidney. She underwent single-port retroperitoneoscopic excision of both aneurysms, with closure of the terminal arterial stump, primary closure of the venous wall defect, and renorrhaphy. The operative time was 95\u202fmin, warm ischemia time was 20\u202fmin, and estimated blood loss was 30\u202fmL. Histopathological examination confirmed the diagnoses. At 4\u202fmonths after surgery, color Doppler ultrasonography demonstrated preserved main left renal arterial flow and intrarenal arterial perfusion without Doppler evidence of hemodynamically significant main renal artery stenosis. Dedicated renal venous Doppler assessment and differential renal function testing were not performed. This case demonstrates that single-port retroperitoneoscopic kidney-sparing excision can be performed in selected patients with concomitant intrarenal arterial and venous aneurysms.<\/jats:p>","DOI":"10.3389\/fmed.2026.1912155","type":"journal-article","created":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T04:22:42Z","timestamp":1786681362000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Kidney-sparing resection of concomitant renal artery and renal vein aneurysms by single-port retroperitoneoscopic surgery: a case report"],"prefix":"10.3389","volume":"13","author":[{"given":"Chi","family":"Gan","sequence":"first","affiliation":[{"name":"Department of Urologic Surgery, Jiangsu Cancer Hospital and Jiangsu Institute of Cancer Research and Affiliated Cancer Hospital of Nanjing Medical University","place":["Nanjing, China"]},{"name":"Department of Urology, The First Affiliated Hospital with Nanjing Medical University","place":["Nanjing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiyi","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Urologic Surgery, Jiangsu Cancer Hospital and Jiangsu Institute of Cancer Research and Affiliated Cancer Hospital of Nanjing Medical University","place":["Nanjing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Da","family":"Zhong","sequence":"additional","affiliation":[{"name":"Department of Urologic Surgery, Jiangsu Cancer Hospital and Jiangsu Institute of Cancer Research and Affiliated Cancer Hospital of Nanjing Medical University","place":["Nanjing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Urologic Surgery, Jiangsu Cancer Hospital and Jiangsu Institute of Cancer Research and Affiliated Cancer Hospital of Nanjing Medical University","place":["Nanjing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Urologic Surgery, Jiangsu Cancer Hospital and Jiangsu Institute of Cancer Research and Affiliated Cancer Hospital of Nanjing Medical University","place":["Nanjing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ninghong","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Urologic Surgery, Jiangsu Cancer Hospital and Jiangsu Institute of Cancer Research and Affiliated Cancer Hospital of Nanjing Medical University","place":["Nanjing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,8,14]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"755","DOI":"10.3949\/ccjm.87a.19140-2","article-title":"Optimal surveillance and treatment of renal and splenic artery aneurysms","volume":"87","author":"Wang","year":"2020","journal-title":"Cleve Clin J Med"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"121","DOI":"10.1186\/s12894-021-00877-6","article-title":"Endovascular management of a large renal artery aneurysm: a case report and review of the literature","volume":"21","author":"Zhu","year":"2021","journal-title":"BMC Urol"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"711","DOI":"10.1016\/j.jvscit.2022.08.012","article-title":"Incidental finding of circumaortic left renal vein aneurysm on imaging","volume":"8","author":"Provenza","year":"2022","journal-title":"J Vasc Surg Cases Innov Tech"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"49","DOI":"10.23736\/S0021-9509.23.12809-6","article-title":"Guidelines on the diagnosis, treatment and management of visceral and renal arteries aneurysms: a joint assessment by the Italian societies of vascular and endovascular surgery (SICVE) and medical and interventional radiology (SIRM)","volume":"65","author":"Pratesi","year":"2024","journal-title":"J Cardiovasc Surg"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"9","DOI":"10.1016\/j.avsg.2021.06.023","article-title":"Contemporary outcomes of in situ open surgical repair of mid-portion and distal renal artery aneurysms","volume":"78","author":"Bilman","year":"2022","journal-title":"Ann Vasc Surg"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"872","DOI":"10.1016\/j.ejvs.2016.02.017","article-title":"Editor's choice -
