When RCC progresses, it is known to form tumor thrombus in the renal vein and\/or inferior vena cava. However, RCC does not normally form tumor thrombus in the ureter or renal pelvis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>A 43-year-old man presented to our department for the treatment of a renal tumor with asymptomatic gross hematuria. In a dynamic CT study, contrast enhancement revealed a tumor suspected to be RCC, but atypical finding as a tumor thrombus that filled the renal pelvis and the whole ureter was also observed. Nephroureterectomy was performed, and the tumor was diagnosed histopathologically as RCC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>We report here a very rare case of RCC with a tumor thrombus in the whole ureter.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1186\/1471-2490-11-16","type":"journal-article","created":{"date-parts":[[2011,8,25]],"date-time":"2011-08-25T14:33:55Z","timestamp":1314282835000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Renal cell carcinoma with a tumor thrombus in the ureter: a case report"],"prefix":"10.1186","volume":"11","author":[{"given":"Osamu","family":"Fujita","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koichiro","family":"Wada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomoya","family":"Yamasaki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daisuke","family":"Manabe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katsuji","family":"Takeda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoko","family":"Nakamura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2011,8,1]]},"reference":[{"key":"184_CR1","unstructured":"TNM Classification of Malignant Tumors.
