Five dogs were presented for evaluation of recurrent urinary tract infections and urinary incontinence. All dogs were bright and alert on presentation, and physical examination findings, complete blood count, and serum biochemistry results were within reference intervals. Plain radiographs and conventional ultrasonography did not reveal any appreciable changes. Following aseptic urethral catheterization, CE\u2010VUS was performed by infusing a second\u2010generation microbubble\u2010based ultrasound contrast agent into the urinary bladder. The contrast agent was observed in both ureters and pelvicalyceal systems in cases one and five and in the left ureter and pelvicalyceal system in cases two, three, and four. Displacement of the ureteral orifices was documented caudal to the bladder trigone in all dogs with EUs. Additionally, a ureterocele associated with the left EU was identified in case three. These findings were consistent with vesicoureteral reflux secondary to EUs. The diagnosis was confirmed by radiographic cystography and\/or computed tomography excretory urography (CTEU). CE\u2010VUS appears to be a useful, radiation\u2010free imaging technique for evaluating urinary tract morphology and function in dogs. To the authors\u2019 knowledge, no previous studies have reported the clinical use of CE\u2010VUS for the diagnosis of EUs in dogs.<\/jats:p>","DOI":"10.1111\/vru.70240","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T09:17:47Z","timestamp":1790155067000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Contrast\u2010Enhanced Voiding Urosonography for Diagnosis of Ectopic Ureters in Five Female Dogs"],"prefix":"10.1111","volume":"67","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5749-5345","authenticated-orcid":false,"given":"Georgia","family":"Trikoupi","sequence":"first","affiliation":[{"name":"Companion Animal Clinic Faculty of Veterinary Medicine Aristotle University of Thessaloniki  Thessaloniki Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5471-4584","authenticated-orcid":false,"given":"Lysimachos","family":"Papazoglou","sequence":"additional","affiliation":[{"name":"Companion Animal Clinic Faculty of Veterinary Medicine Aristotle University of Thessaloniki  Thessaloniki Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9708-3217","authenticated-orcid":false,"given":"Paraskevi","family":"Papadopoulou","sequence":"additional","affiliation":[{"name":"Companion Animal Clinic Faculty of Veterinary Medicine Aristotle University of Thessaloniki  Thessaloniki Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,23]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.2003.223.475"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.13055"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1053\/svms.2000.7302"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cvsm.2013.11.007"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cvsm.2018.11.003"},{"key":"e_1_2_12_7_1","first-page":"303","article-title":"Ectopic Ureters and Ureteroceles in Dogs: Presentation, Cause, and Diagnosis","volume":"26","author":"Sutherland\u2010Smith J.","year":"2004","journal-title":"Compendium: Continuing Education for Veterinarians"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/avj.12147"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13028\u2010022\u201000648\u20109"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/jsap.12460"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.2003.223.817"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.2004.224.1607"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/jsap.13489"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.3390\/ani15131918"},{"key":"e_1_2_12_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.12867"},{"key":"e_1_2_12_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.12934"},{"key":"e_1_2_12_17_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00247\u2010013\u20102832\u20109"},{"key":"e_1_2_12_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00247\u2010007\u20100529\u20107"},{"key":"e_1_2_12_19_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00247\u2010020\u201004906\u20108"},{"key":"e_1_2_12_20_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00247\u2010021\u201005116\u20106"},{"key":"e_1_2_12_21_1","doi-asserted-by":"publisher","DOI":"10.5152\/tud.2018.76702"},{"key":"e_1_2_12_22_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.13315"},{"key":"e_1_2_12_23_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740\u20108261.1998.tb00343.x"},{"key":"e_1_2_12_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cvsm.2015.02.010"},{"key":"e_1_2_12_25_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.237.2.191"},{"key":"e_1_2_12_26_1","doi-asserted-by":"publisher","DOI":"10.1111\/jvim.15424"},{"key":"e_1_2_12_27_1","doi-asserted-by":"publisher","DOI":"10.1111\/jsap.13399"},{"key":"e_1_2_12_28_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651\u20102227.2011.02588.x"},{"key":"e_1_2_12_29_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00330\u2010024\u201011079\u20107"}],"container-title":["Veterinary Radiology &amp;
