A 9-month-old male child was admitted to our hospital with persistent haematuria, dysuria and anaemia. Investigations revealed a retroperitoneal cyst abutting the hydronephrotic non-functioning right kidney. At surgery an isolated retroperitoneal cyst communicating with the right pelviureteric junction was found. The kidney and associated cyst were excised. Histology of the cystic lesion revealed an enteric duplication cyst lined by ectopic gastric mucosa. Isolated retroperitoneal enteric duplication cyst communicating with the urinary tract has not been previously reported in the English literature. We propose that acid secretion into the right renal system was the cause of the haematuria\u2013dysuria syndrome which promptly resolved postoperatively.<\/jats:p>","DOI":"10.1136\/bcr-2013-202449","type":"journal-article","created":{"date-parts":[[2014,5,9]],"date-time":"2014-05-09T11:17:15Z","timestamp":1399634235000},"page":"bcr2013202449","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["A retroperitoneal enteric duplication cyst communicating with the right upper ureter in an infant"],"prefix":"10.1136","volume":"2014","author":[{"given":"Harshjeet Singh","family":"Bal","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sundeep","family":"Kisku","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sudipta","family":"Sen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dipti","family":"Masih","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2014,5,9]]},"reference":[{"key":"2025042703365327000_2014.may09_1.bcr2013202449.1","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3468(95)90482-4"},{"key":"2025042703365327000_2014.may09_1.bcr2013202449.2","first-page":"118","article-title":"Alimentary tract duplications in children: report of 26 years\u2019 experience","volume":"42","author":"Karnak","year":"2000","journal-title":"Turkish J Pediatr"},{"key":"2025042703365327000_2014.may09_1.bcr2013202449.3","doi-asserted-by":"crossref","first-page":"e5","DOI":"10.1016\/j.jpedsurg.2004.04.040","article-title":"Isolated enteric duplication cysts","volume":"39","author":"Menon","year":"2004","journal-title":"J Pediatr Surg"},{"key":"2025042703365327000_2014.may09_1.bcr2013202449.4","doi-asserted-by":"publisher","DOI":"10.1007\/s00247-007-0476-3"},{"key":"2025042703365327000_2014.may09_1.bcr2013202449.5","doi-asserted-by":"publisher","DOI":"10.1007\/s00383-011-3036-8"},{"key":"2025042703365327000_2014.may09_1.bcr2013202449.6","doi-asserted-by":"publisher","DOI":"10.1007\/s00383-008-2220-y"},{"key":"2025042703365327000_2014.may09_1.bcr2013202449.7","doi-asserted-by":"publisher","DOI":"10.1016\/j.epsc.2013.05.012"},{"key":"2025042703365327000_2014.may09_1.bcr2013202449.8","first-page":"108126","article-title":"Infected completely isolated enteric duplication cyst management with percutaneous drainage and surgical excision after retreat of infection: a case report","volume":"2013","author":"Kyriakos","year":"2013","journal-title":"Case Rep Surg"},{"key":"2025042703365327000_2014.may09_1.bcr2013202449.9","doi-asserted-by":"publisher","DOI":"10.4103\/0975-5950.85844"},{"key":"2025042703365327000_2014.may09_1.bcr2013202449.10","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.18004619904"},{"key":"2025042703365327000_2014.may09_1.bcr2013202449.11","doi-asserted-by":"publisher","DOI":"10.1007\/s00383-005-1517-3"},{"key":"2025042703365327000_2014.may09_1.bcr2013202449.12","first-page":"492","article-title":"Retroperitoneal enteric duplication cyst presenting as a pancreatic cystic lesion.
