The oliguric phase lasted only 24\u2005h followed by prolonged polyuria for 20\u2005days, with urine output in excess of 16\u2005L\/day at maximum. As indexed in PubMed this is only the second published case of this nature since 1974, in which an abrupt oliguric phase of 24\u2005h or less heralded prolonged polyuria in ATN. The diagnosis is challenging as fractional excretion of sodium early in the clinical course and rapid normalisation of serum creatinine with intravenous fluids (IVF) may point towards prerenal azotaemia resulting in a premature discharge from hospital. Patients with an abrupt oliguric phase may suffer a secondary renal insult from the profound fluid loss that is to follow and may need inpatient monitoring with supplemental IVF to prevent deleterious outcomes.<\/jats:p>","DOI":"10.1136\/bcr-2013-201030","type":"journal-article","created":{"date-parts":[[2014,8,22]],"date-time":"2014-08-22T11:36:14Z","timestamp":1408707374000},"page":"bcr2013201030","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Acute tubular necrosis (ATN) presenting with an unusually prolonged period of marked polyuria heralded by an abrupt oliguric phase"],"prefix":"10.1136","volume":"2014","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9074-9522","authenticated-orcid":false,"given":"Virin","family":"Ramoutar","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristian","family":"Landa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leighton R","family":"James","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2014,8,22]]},"reference":[{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.1","first-page":"379","article-title":"Renal function studies in acute tubular necrosis","volume":"9","author":"Bull","year":"1950","journal-title":"Clin Sci"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.2","doi-asserted-by":"publisher","DOI":"10.1159\/000167251"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.3","doi-asserted-by":"publisher","DOI":"10.1093\/ndt\/gfr331"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.4","doi-asserted-by":"publisher","DOI":"10.1097\/01.CCM.0000266684.17500.2F"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.5","doi-asserted-by":"publisher","DOI":"10.1093\/ndt\/gfl541"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.6","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.ndt.a027871"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.7","doi-asserted-by":"publisher","DOI":"10.1089\/10507250252949478"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.8","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ki.5002475"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.9","doi-asserted-by":"publisher","DOI":"10.1152\/ajprenal.00384.2004"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.10","doi-asserted-by":"publisher","DOI":"10.1086\/318457"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.11","doi-asserted-by":"publisher","DOI":"10.1159\/000180409"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.12","first-page":"660","article-title":"Repair of the nephron following temporary occlusion of the renal pedicle","volume":"17","author":"Cuppage","year":"1967","journal-title":"Lab Invest"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.13","first-page":"327","article-title":"Repair of the nephron in acute renal failure: comparative regeneration following various forms of acute tubular injury","volume":"32","author":"Cuppage","year":"1968","journal-title":"Pathol Microbiol (Basel)"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.14","first-page":"851","article-title":"Cell renewal following dichromate-induced renal tubular necrosis: an enzyme histochemical study","volume":"47","author":"Baines","year":"1965","journal-title":"Am J Pathol"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.15","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9343(53)90143-0"},{"key":"2025042706221324000_2014.aug22_1.bcr2013201030.16","doi-asserted-by":"publisher","DOI":"10.1038\/ki.1972.33"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2013-201030","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T13:22:26Z","timestamp":1745760146000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2013-201030"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,8,22]]},"references-count":16,"alternative-id":["10.1136\/bcr-2013-201030"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2013-201030","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,8,22]]}}}
