Presenting often with haematuria and obstructive symptoms, these lesions pose diagnostic and therapeutic challenges, with no established management guidelines.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Presentation<\/jats:title>\n                    <jats:p>We report a case of a 41\u2010year\u2010old woman who presented with left\u2010sided flank pain, fever and visible haematuria. Initial imaging revealed hydronephrosis and a proximal ureteric soft tissue lesion. Flexible ureteroscopy identified a large, pale and fleshy intraluminal mass extending into the pelviureteric junction. Laser ablation and endoscopic resection were performed, and histopathology confirmed a polypoid AVM. Postoperative recovery was uneventful, apart from a conservatively managed renal abscess. The patient remained asymptomatic at 12\u2010month follow\u2010up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This case highlights a rare presentation of ureteric AVM and supports flexible ureteroscopy with laser ablation as a viable and minimally invasive treatment modality. Clinicians should consider vascular anomalies in patients with unexplained haematuria, particularly when conventional aetiologies are excluded.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1155\/criu\/3037053","type":"journal-article","created":{"date-parts":[[2026,4,16]],"date-time":"2026-04-16T06:12:46Z","timestamp":1776319966000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Arteriovenous Malformation of the Ureter: A Rare Urological Entity Managed With Endoscopic Laser Ablation"],"prefix":"10.1155","volume":"2026","author":[{"given":"A.","family":"Anber","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-1477-7829","authenticated-orcid":false,"given":"J.","family":"Kyeremeh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Coscione","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.","family":"Dragos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Ahmed","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,4,15]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.12968\/bjon.2014.23.Sup9.S28"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.4103\/0970-1591.37181"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0090-4295(92)90462-6"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.4103\/UA.UA_24_20"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eucr.2018.04.001"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1464-410X.1997.00384.x"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5347(01)64166-1"},{"key":"e_1_2_9_8_2","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000011954"},{"key":"e_1_2_9_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/CM9.0000000000002997"},{"key":"e_1_2_9_10_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12894-017-0237-z"}],"container-title":["Case Reports in Urology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/criu\/3037053","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1155\/criu\/3037053","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/criu\/3037053","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,16]],"date-time":"2026-04-16T06:12:47Z","timestamp":1776319967000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/criu\/3037053"}},"subtitle":[],"editor":[{"given":"Kalyani","family":"Sen","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]}],"short-title":[],"issued":{"date-parts":[[2026,1]]},"references-count":10,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026,1]]}},"alternative-id":["10.1155\/criu\/3037053"],"URL":"https:\/\/doi.org\/10.1155\/criu\/3037053","archive":["Portico"],"relation":{},"ISSN":["2090-696X","2090-6978"],"issn-type":[{"value":"2090-696X","type":"print"},{"value":"2090-6978","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1]]},"assertion":[{"value":"2025-08-04","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-03-30","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-04-15","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"3037053"}}
