ABSTRACT

Background: The ability of multidetector computed tomography (MDCT) with or without protocol Computed Tomography Urography (CTU) allows to evaluate the genitourinary tract completely. Objective: Knowing the characteristics MDCT urothelial tumors and other lesions that occur as intraluminal filling defects. Material and methods: Ambispective study initiated February, 2005 to November, 2014 of those cases referred to MDCT by hematuria and / or urothelial lesion known. This included 160 patients, 171 studies with MDCT 8 and 16 abdominopelvic or with CTU. Results: All transitional cell carcinoma (TCC) demonstrated was 46 patients (29%) (11 with known history in which it showed recurrence in 10 [6%] and recently, unexpected and incidental diagnosis supported by imaging findings in 36 (22%) with histopathologic confirmation, corresponding to urothelial neoplasms, the TCC type. In 99 patients (62%), based on the findings of MDCT, were completed as characterizable: 75 (46%) were classified as characterizable, highly suspicious by the approach of study, by subsequent hypervascular behavior after intravenous contrast and in 24 (15% of all studies) were classified as no characterized by the approach of study or subsequent intravenous contrast hypovascular behavior. Conclusions: Three-phase MDCT with intravenous contrast is the most complete technique for diagnosis, staging and surgical planning urothelial neoplasms, and must include the entire tract reno-ureterovesical.
