Although renal pelvis TCC is relatively rare in terms of urologic malignancies, it is the most common tumor originating in renal pelvis.<\/jats:p>\n <\/jats:sec>\n \n Case presentation:<\/jats:title>\n A 75-year-old woman presented with gross hematuria found to have a filling defect in the renal pelvis with retrograde pyelogram and cytology showed clusters of urothelial cells, with imaging suspicious for TCC. Patient underwent robotic nephroureterectomy with partial cystectomy. Pathology analysis revealed RCC.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n RCC may occur in the renal pelvis mimicking TCC. Extensive preoperative evaluation to accurately diagnose tumor is key to avoid unnecessary procedures. Intraoperative pathologic evaluation is emphasized with inconclusive preoperative results.<\/jats:p>\n <\/jats:sec>","DOI":"10.1089\/cren.2020.0180","type":"journal-article","created":{"date-parts":[[2020,12,29]],"date-time":"2020-12-29T16:50:56Z","timestamp":1609260656000},"page":"536-539","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Right Renal Pelvis Renal Cell Carcinoma Mimicking Transitional Cell Carcinoma: Case Report"],"prefix":"10.1177","volume":"6","author":[{"given":"Fahad","family":"Sheckley","sequence":"first","affiliation":[{"name":"Department of Urology, Hackensack University Medical Center, Hackensack, New Jersey, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Craig","family":"Nobert","sequence":"additional","affiliation":[{"name":"Department of Urology, Mount Sinai Health System, New York, New York, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Stifelman","sequence":"additional","affiliation":[{"name":"Department of Urology, Hackensack University Medical Center, Hackensack, New Jersey, USA."},{"name":"Department of Urology, John Theurer Cancer Center, Hackensack, New Jersey, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,3,10]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02923956"},{"key":"e_1_3_3_3_2","doi-asserted-by":"crossref","first-page":"1989","DOI":"10.1016\/j.ejso.2020.06.024","article-title":"Diagnostic accuracy of ureteroscopic biopsy in predicting stage and grade at final pathology in upper tract urothelial carcinoma: Systematic review and meta-analysis","volume":"46","author":"Subiela JD","year":"2020","unstructured":"Subiela JD, , Territo A, , Mercade A, et al.
