This syndrome frequently results in morphological defects such as ectopia and malrotation. These structural alterations can lead to ureteropelvic junction obstruction, kidney stones and urinary tract infections. Urolithiasis is a common consequence of the HSK. This case report describes the surgical treatment of ureteric calculus in a boy with an HSK using laparoscopic techniques.<\/jats:p>","DOI":"10.1136\/bcr-2025-266467","type":"journal-article","created":{"date-parts":[[2025,11,11]],"date-time":"2025-11-11T08:05:20Z","timestamp":1762848320000},"page":"e266467","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Laparoscopic ureterolithotomy in a child with horseshoe kidney"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6176-6913","authenticated-orcid":false,"given":"Naveen","family":"Kumar","sequence":"first","affiliation":[{"name":"Urology, All India Institute of Medical Sciences - Patna, Patna, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeetendra","family":"Jaidiya","sequence":"additional","affiliation":[{"name":"Urology, All India Institute of Medical Sciences - Patna, Patna, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nitish","family":"Kumar","sequence":"additional","affiliation":[{"name":"Urology, All India Institute of Medical Sciences - Patna, Patna, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9401-9404","authenticated-orcid":false,"given":"Vipin","family":"Chandra","sequence":"additional","affiliation":[{"name":"Urology, All India Institute of Medical Sciences - Patna, Patna, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,11,10]]},"reference":[{"key":"2025111100051549000_18.11.e266467.1","doi-asserted-by":"crossref","first-page":"683","DOI":"10.1590\/S1677-5538.IBJU.2014.0086","article-title":"Flexible Ureteroscopic Management of Horseshoe Kidney Renal Calculi","volume":"41","author":"Ding","year":"2015","journal-title":"Int Braz J Urol"},{"key":"2025111100051549000_18.11.e266467.2","unstructured":"Bauer S .
