However, single ureter draining crossed fused renal ectopia is a rare occurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case report<\/jats:title>\n                    <jats:p>Here, we report a case of crossed fused renal ectopia with a single ureter in a 46-year-old Nepali male who presented with history of lithuria. Computed tomography revealed that the left kidney was situated on the right side and fused with the right kidney. The renal pelvises of both kidneys were fused, and a single ureter, located on the right side, was draining both kidneys into the bladder. The patient was advised to have regular follow-ups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Crossed fused renal ectopia with a single ureter represents a rare renal anomaly. Asymptomatic patients can typically be managed conservatively. Regular follow-up is recommended to monitor renal function, calculus formation, infections, and malignant changes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1186\/s13256-024-04689-8","type":"journal-article","created":{"date-parts":[[2024,8,3]],"date-time":"2024-08-03T20:02:34Z","timestamp":1722715354000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["An uncommon encounter: crossed fused renal ectopia with singular ureter: a case report"],"prefix":"10.1186","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-3016-7602","authenticated-orcid":false,"given":"Prajwal","family":"Dahal","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kapil","family":"Dawadi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ongden Yonjen","family":"Tamang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sabina","family":"Parajuli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natasha","family":"Dhakal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,8,4]]},"reference":[{"key":"4689_CR1","doi-asserted-by":"publisher","first-page":"S5","DOI":"10.4172\/2161-0940.S5-001","volume":"5","author":"CSR Babu","year":"2015","unstructured":"Babu CSR, Sharma V, Gupta OP.
