Its presentation with pelviureteric junction obstruction presents a confusing intraoperative finding. We report two cases of ERC with pelviureteric junction obstruction in the ectopic kidney. Emphasis is laid on the defining the anatomy so that reader can identify the condition if he comes across similar situation. The two patients were managed by minimal access approach. Management of these cases and review of pediatric cases reported in literature are discussed.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/jiaps.jiaps_100_20","type":"journal-article","created":{"date-parts":[[2021,5,15]],"date-time":"2021-05-15T13:29:02Z","timestamp":1621085342000},"page":"195-197","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Pelviureteric Junction Obstruction in Ectopic Kidneys with Extrarenal Calyces"],"prefix":"10.4103","volume":"26","author":[{"given":"Ravi Prakash","family":"Kanojia","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karmon","family":"Janssen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Kirsch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-12-20240905","doi-asserted-by":"crossref","first-page":"1581","DOI":"10.2147\/OPTH.S164641","article-title":"Myopia prevalence and risk factors in children","volume":"12","author":"Theophanous","year":"2018","journal-title":"Clin Ophthalmol"},{"key":"R2-12-20240905","doi-asserted-by":"crossref","first-page":"188","DOI":"10.1089\/end.2006.20.188","article-title":"Case report: Transmesocolic laparoscopic reconstruction of ureteropelvic junction obstruction in pelvic kidney associated with extrarenal calices","volume":"20","author":"Wadhwa","year":"2006","journal-title":"J Endourol"},{"key":"R3-12-20240905","first-page":"143","article-title":"Extrarenal calyces mimicking retroperitoneal cystic mass with concomitant ureteropelvic junction obstruction: Renal pelvis reconstruction using calyx unification","volume":"11","author":"Wahyudi","year":"2019","journal-title":"Res Rep Urol"},{"key":"R4-12-20240905","doi-asserted-by":"crossref","first-page":"406","DOI":"10.1016\/S0022-5347(17)61968-2","article-title":"Extrarenal calyces in the ectopic kidney","volume":"103","author":"Dretler","year":"1970","journal-title":"J Urol"},{"key":"R5-12-20240905","doi-asserted-by":"crossref","first-page":"249","DOI":"10.1016\/j.ajur.2018.12.006","article-title":"Revisiting the morphology of pelvicalyceal system in human cadaveric kidneys with a systematic review of literature","volume":"6","author":"Gandhi","year":"2019","journal-title":"Asian J Urol"},{"key":"R6-12-20240905","first-page":"823","article-title":"Extrarenal calyces: Their relationship to renal disease","volume":"86","author":"Malament","year":"1961","journal-title":"Am J Roentgenol Radium Ther Nucl Med"}],"container-title":["Journal of Indian Association of Pediatric Surgeons"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/jiaps.JIAPS_100_20","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T15:14:10Z","timestamp":1787843650000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/jiaps.JIAPS_100_20"}},"subtitle":["A Rare Renal Anomaly"],"short-title":[],"issued":{"date-parts":[[2021,5]]},"references-count":6,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2021]]}},"URL":"https:\/\/doi.org\/10.4103\/jiaps.jiaps_100_20","relation":{},"ISSN":["0971-9261"],"issn-type":[{"value":"0971-9261","type":"print"}],"subject":[],"published":{"date-parts":[[2021,5]]}}}
