XGP\u2019s exact etiology remains unclear, although it is frequently associated with chronic urinary obstruction and infections within the urinary tract. Superinfections such as <jats:italic>Escherichia coli<\/jats:italic>, <jats:italic>Proteus mirabilis<\/jats:italic>, and occasionally <jats:italic>Pseudomonas<\/jats:italic> species typically cause XGP. Documented cases of <jats:italic>Raoultella ornithinolytica<\/jats:italic> (<jats:italic>R. ornithinolytica<\/jats:italic>) infections in humans, particularly within the urinary tract, are limited. However, advancements in diagnostic techniques are expected to increase the detection of such rare pathogens. To the best of our knowledge, currently, there is no evidence in the literature indicating that this pathogen is responsible for XGP. We present a case of XGP in which we isolated <jats:italic>R. ornithinolytica<\/jats:italic> and discuss its treatment in the current literature.<\/jats:p>","DOI":"10.3897\/folmed.67.e139995","type":"journal-article","created":{"date-parts":[[2025,6,16]],"date-time":"2025-06-16T14:42:12Z","timestamp":1750084932000},"source":"Crossref","is-referenced-by-count":1,"title":["Xanthogranulomatous pyelonephritis caused by an unusual pathogen Raoultella ornithinolytica: a case report"],"prefix":"10.3897","volume":"67","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-2789-2005","authenticated-orcid":true,"given":"Atalay","family":"Kutlu","sequence":"first","affiliation":[{"name":"Department of Urology, Basaksehir Cam Sakura City Hospital, Istanbul, Turkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7147-8288","authenticated-orcid":true,"given":"Akif","family":"Erbin","sequence":"additional","affiliation":[{"name":"Department of Urology, Basaksehir Cam Sakura City Hospital, Istanbul, Turkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1131-2507","authenticated-orcid":true,"given":"Turan","family":"Ozdemir","sequence":"additional","affiliation":[{"name":"Department of Urology, Basaksehir Cam Sakura City Hospital, Istanbul, Turkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-1231-5330","authenticated-orcid":true,"given":"Ahmet Eren","family":"Sagir","sequence":"additional","affiliation":[{"name":"Department of Urology, Basaksehir Cam Sakura City Hospital, Istanbul, Turkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6720-0662","authenticated-orcid":true,"given":"Begum Calim","family":"Gurbuz","sequence":"additional","affiliation":[{"name":"Department of Pathology, Basaksehir Cam Sakura City Hospital, Istanbul, Turkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6481-7907","authenticated-orcid":true,"given":"Halil Lutfi","family":"Canat","sequence":"additional","affiliation":[{"name":"Department of Urology, Basaksehir Cam Sakura City Hospital, Istanbul, Turkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2258","published-online":{"date-parts":[[2025,6,16]]},"reference":[{"key":"139995_B1","unstructured":"1.
