Here, we report a rare condition, an IgG4-related disease involving the bilateral renal pelvises, which was successfully treated with steroid therapy. A 64-year-old female was admitted with left flank pain and hematuria. Computed tomographic images showed irregular enhancing masses around the bilateral renal pelvises and lymph nodes in the left para-aortic area. A histopathological examination of a renal needle biopsy revealed numerous cells that were positive for IgG and more than 10 IgG4-positive cells per high-powered field. The IgG4\/IgG ratio was more than 40%. Her serum IgG4 level was elevated to 1440 mg\/dL, and her IgG4\/IgG ratio was 82.1%. After a diagnosis of IgG4 sclerosing disease, a double-J ureteral stent was inserted and steroid therapy was performed for 20 weeks. Her symptoms dramatically improved, and the follow-up images showed a resolved state. There was no relapse of the disease for more than 6 months after the removal of the stent.<\/jats:p>","DOI":"10.4103\/1319-2442.397207","type":"journal-article","created":{"date-parts":[[2024,3,9]],"date-time":"2024-03-09T00:55:51Z","timestamp":1709945751000},"page":"449-454","source":"Crossref","is-referenced-by-count":0,"title":["IgG4-Related Diseases Involving Bilateral Renal Pelvises Successfully Treated with Steroid Therapy"],"prefix":"10.4103","volume":"34","author":[{"given":"Illyoung","family":"Seo","sequence":"first","affiliation":[{"name":"Department of Urology, Institute of Wonkwang Medical Science, Wonkwang University School of Medicine and Hospital, Iksan, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youri","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Radiology, Institute of Wonkwang Medical Science, Wonkwang University School of Medicine and Hospital, Iksan, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2024,3,11]]},"reference":[{"key":"R1-20240314","doi-asserted-by":"crossref","first-page":"3061","DOI":"10.1002\/art.34593","article-title":"Recommendations for the nomenclature of IgG4-related disease and its individual organ system manifestations","volume":"64","author":"Stone","year":"2012","journal-title":"Arthritis Rheum"},{"key":"R2-20240314","doi-asserted-by":"crossref","first-page":"44","DOI":"10.1186\/s12894-015-0041-6","article-title":"IgG4-related kidney disease from the renal pelvis that mimicked urothelial carcinoma: A case report","volume":"15","author":"Zhang","year":"2015","journal-title":"BMC Urol"},{"key":"R3-20240314","doi-asserted-by":"crossref","first-page":"1897","DOI":"10.2169\/internalmedicine.54.4507","article-title":"IgG4-related disease: A mass lesion in the intrarenal sinus near the renal pelvis","volume":"54","author":"Inenaga","year":"2015","journal-title":"Intern Med"},{"key":"R4-20240314","doi-asserted-by":"crossref","first-page":"615","DOI":"10.1007\/s10157-011-0521-2","article-title":"Proposal for diagnostic criteria for IgG4-related kidney disease","volume":"15","author":"Kawano","year":"2011","journal-title":"Clin Exp Nephrol"},{"key":"R5-20240314","doi-asserted-by":"crossref","first-page":"14","DOI":"10.1136\/annrheumdis-2013-204907","article-title":"The diagnostic utility of serum IgG4 concentrations in IgG4-related disease","volume":"74","author":"Carruthers","year":"2015","journal-title":"Ann Rheum Dis"},{"key":"R6-20240314","doi-asserted-by":"crossref","first-page":"447","DOI":"10.1016\/j.anai.2015.04.011","article-title":"IgG4-related disease: A primer on diagnosis and management","volume":"114","author":"Ghably","year":"2015","journal-title":"Ann Allergy Asthma Immunol"},{"key":"R7-20240314","doi-asserted-by":"crossref","first-page":"580814","DOI":"10.1155\/2012\/580814","article-title":"Cutoff values of serum IgG4 and histopathological IgG4+ plasma cells for diagnosis of patients with IgG4-related disease","volume":"2012","author":"Masaki","year":"2012","journal-title":"Int J Rheumatol"},{"key":"R8-20240314","doi-asserted-by":"crossref","first-page":"e4002","DOI":"10.1097\/MD.0000000000004002","article-title":"Therapeutic approach to IgG4-related disease: A systematic review","volume":"95","author":"Brito-Zer\u00f3n","year":"2016","journal-title":"Medicine (Baltimore)"},{"key":"R9-20240314","doi-asserted-by":"crossref","first-page":"825","DOI":"10.1097\/MPA.0b013e318ac522f","article-title":"A case of IgG4-related sclerosing disease with retroperitoneal fibrosis, autoimmune pancreatitis and bilateral focal nephritis","volume":"38","author":"Van","year":"2009","journal-title":"Pancreas"},{"key":"R10-20240314","doi-asserted-by":"crossref","first-page":"1688","DOI":"10.1002\/art.39132","article-title":"International consensus guidance statement on the management and treatment of IgG4-related disease","volume":"67","author":"Khosroshahi","year":"2015","journal-title":"Arthritis Rheumatol"}],"container-title":["Saudi Journal of Kidney Diseases and Transplantation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/1319-2442.397207","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,26]],"date-time":"2026-08-26T18:27:27Z","timestamp":1787768847000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/1319-2442.397207"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023]]},"references-count":10,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2023]]}},"URL":"https:\/\/doi.org\/10.4103\/1319-2442.397207","relation":{},"ISSN":["1319-2442","2320-3838"],"issn-type":[{"value":"1319-2442","type":"print"},{"value":"2320-3838","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023]]}}}
