case_images: Computed tomography (CT) chest abdomen pelvis was obtained without contrast given the patient's acute kidney injury (AKI) showing a dense opacity in the right lower lobe, small bilateral pleural effusions, left kidney moderately atrophic compared with right, moderate left-sided hydronephrosis, and mild bladder wall thickening (as shown in Figure 1).
case_images: Computed tomography urogram performed on day 2 showing obstruction in the left ureteropelvic junction.

case_images: CT urogram, and left ureteropelvic junction (UPJ) dilation with stent placement. Cystoscopy revealed a mass in the left UPJ (stent placed, Figure 2) and a posterior bladder wall mass (resected, Figure 3).
case_images: Cystoscopy performed on day 2 showing a discrete mass in the posterior bladder wall. This mass was later resected and confirmed as high-grade papillary urothelial carcinoma with high suspicion for early lamina propia invasion.
