Key clinical and demographic features were analysed and compared with the published literature.<\/jats:p><\/jats:sec>Results<\/jats:title>XGP<\/jats:styled-content> was diagnosed in 35 patients over a 12\u2010year (2001\u20132013) period in A<\/jats:styled-content>uckland P<\/jats:styled-content>ublic H<\/jats:styled-content>ospital. Ninety\u2010one percent of the patients were female. The population had significantly higher numbers of M<\/jats:styled-content>aori and P<\/jats:styled-content>acific I<\/jats:styled-content>sland patients compared with the general population (74%). Staghorn calculi were the most common cause (51.4%) with obstructing ureteric calculi as the next most common (22.9%) cause. Twenty percent of cases were not thought to be XGP<\/jats:styled-content> prior to nephrectomy (suspicious renal mass). Thirteen (38%) patients suffered serious complications post\u2010operatively (C<\/jats:styled-content>lavien 3\u20135).<\/jats:p><\/jats:sec>Conclusion<\/jats:title>XGP<\/jats:styled-content> is a rare chronic inflammatory condition that appears to be overrepresented by M<\/jats:styled-content>aori and P<\/jats:styled-content>acific islanders in our cohort when compared with the overall patient pool. Surgical treatment is associated with significant morbidity but remains the only definitive option. Obesity and other conditions associated with metabolic syndrome may coexist at the time of presentation and may be contributing factors to the development of XGP<\/jats:styled-content> and poor outcomes associated with it.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ans.12581","type":"journal-article","created":{"date-parts":[[2014,3,25]],"date-time":"2014-03-25T07:43:38Z","timestamp":1395733418000},"page":"150-153","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Analysis of 35 cases of X<\/scp>anthogranulomatous pyelonephritis"],"prefix":"10.1111","volume":"85","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8947-5480","authenticated-orcid":false,"given":"Ben","family":"Addison","sequence":"first","affiliation":[{"name":"Department of General Surgery North Shore Hospital Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8424-1087","authenticated-orcid":false,"given":"Homayoun","family":"Zargar","sequence":"additional","affiliation":[{"name":"Department of Urology Auckland City Hospital Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikola","family":"Lilic","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology Head and Neck Surgery Middlemore Hospital Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Merrilees","sequence":"additional","affiliation":[{"name":"Department of Urology Auckland City Hospital Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Rice","sequence":"additional","affiliation":[{"name":"Department of Urology Auckland City Hospital Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2014,3,25]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2007.09.026"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11255-010-9778-8"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.crad.2007.04.008"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-410X.2009.08547.x"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1015-9584(09)60099-3"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2006.07.009"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1089\/end.2005.19.813"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijid.2008.06.033"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2008.05.017"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.sla.0000133083.54934.ae"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1097\/SLA.0b013e3181b13ca2"},{"key":"e_1_2_6_13_1","volume-title":"New Zealand Census of Population and Dwellings 2006: Families and Households","author":"Zealand SN","year":"2006"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(12)61851-0"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(11)61780-7"},{"key":"e_1_2_6_16_1","first-page":"U996","article-title":"Population need and geographical access to general practitioners in rural New Zealand","volume":"117","author":"Brabyn L","year":"2004","journal-title":"N.
