We describe the clinical presentation and management of a 3.5-year-old boy with hereditary xanthinuria (an autosomal recessive disorder of purine metabolism) and primary bladder calculus formed from xanthine. To our knowledge this case demonstrates a previously undescribed form of xanthinuria in childhood. Xanthine stones, although rare, should be considered in the diagnosis of urolithiasis.<\/jats:p>","DOI":"10.1159\/000030458","type":"journal-article","created":{"date-parts":[[2003,4,15]],"date-time":"2003-04-15T17:26:45Z","timestamp":1050427605000},"page":"242-244","source":"Crossref","is-referenced-by-count":7,"title":["Xanthine Stone in the Urinary Bladder of a Male Child"],"prefix":"10.1159","volume":"63","author":[{"given":"Andr\u00e1s","family":"Kiss","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mih\u00e1ly","family":"Ber\u00e9nyi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00c1goston","family":"Csontai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2000,1,27]]},"container-title":["Urologia Internationalis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/30458","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/30458","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T04:31:04Z","timestamp":1745469064000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000030458"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1999]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2000,1,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000030458","archive":["Portico"],"relation":{},"ISSN":["0042-1138","1423-0399"],"issn-type":[{"type":"print","value":"0042-1138"},{"type":"electronic","value":"1423-0399"}],"subject":[],"published":{"date-parts":[[1999]]}}}
