A renal mass was detected by ultrasonography and, following total nephrectomy, diagnosed as necrotising pyelonephritis. After surgery, the haematological parameters and erythropoietin values returned to normal, suggesting that the pyelonephritis was the cause of the polycythaemia. While secondary polycythaemia because of a non\u2010neoplastic condition of the kidneys occasionally occurs in human beings, it has only extremely rarely been reported in dogs. This is the first case report of a unilateral pyelonephritis causing secondary polycythaemia in a dog.<\/jats:bold> <\/jats:p>","DOI":"10.1111\/j.1748-5827.2008.00550.x","type":"journal-article","created":{"date-parts":[[2008,5,12]],"date-time":"2008-05-12T12:16:36Z","timestamp":1210594596000},"page":"363-366","source":"Crossref","is-referenced-by-count":9,"title":["Secondary polycythaemia associated with high plasma erythropoietin concentrations in a dog with a necrotising pyelonephritis"],"prefix":"10.1111","volume":"49","author":[{"given":"M.","family":"Kessler","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2008,7,4]]},"reference":[{"key":"e_1_2_4_2_1","first-page":"1009","article-title":"Volume studies.
