Simultaneous robot-assisted approach in a super-elderly patient with urothelial carcinoma and synchronous contralateral renal cell carcinoma: A case report

Figure 2 After admission, computed tomography urography was performed to obtain exact image of tumor distribution. A 1.6 cm-sized mass was observed in the left proximal ureter’s distal portion with suspicious periureteral soft tissue invasion. No regional lymph node enlargement was founded. A: Axial; B: Coronal. 3.1 cm-sized lobulation, relatively homogeneous enhancing mass was observed. Intratumoral cyst with focal oval low density area was founded. Most likely renal cell carcinoma.
