Matrix stones consist of a proteinaceous material which has a radiolucent appearance that might be overlooked on imaging. Recently, endourological intervention has been the standard treatment method for matrix stones. We report a case of urinary matrix stones in a patient with type 1 diabetes mellitus and chronic kidney disease, in whom the stones formed into a pure matrix and were not visualized in the computed tomography scan. The stones were found after additional work-up, and they were managed using a transureteral stone basket, not through endourological intervention.<\/jats:p>","DOI":"10.4082\/kjfm.20.0095","type":"journal-article","created":{"date-parts":[[2022,1,23]],"date-time":"2022-01-23T18:25:42Z","timestamp":1642962342000},"page":"86-89","update-policy":"https:\/\/doi.org\/10.4082\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Radiolucent Pure Matrix Stones on Computed Tomography Scan, Arising in Patient with Type I Diabetes and Chronic Kidney Disease: A Case Report"],"prefix":"10.4082","volume":"43","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7848-0919","authenticated-orcid":true,"given":"Young-Woong","family":"Song","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3494-3301","authenticated-orcid":true,"given":"Ju-heon","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8469-2010","authenticated-orcid":true,"given":"Kitae","family":"Bang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8909-3404","authenticated-orcid":true,"given":"Jong Ho","family":"Shin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5414-4339","authenticated-orcid":true,"given":"Kyeong Min","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1786-0448","authenticated-orcid":true,"given":"Jinuk","family":"Jeong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2550","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1097\/01.ju.0000145868.18824.25"},{"key":"ref2","first-page":"810","volume-title":"The management of renal matrix calculi: a single-centre experience over 5 years","author":"Shah","year":"2009"},{"key":"ref3","first-page":"378","volume-title":"V.
