case_images: CT indicated extensive exudation and edema in the bilateral renal pelvis, ureter, and bladder, together with dilatation and effusion in the renal pelvis and ureter (Figures 1-3). Cystoscopy showed extensive congestion, edema, and erosion in the bladder epithelium.

case_images: CT indicated extensive exudation and edema in the bilateral renal pelvis, ureter, and bladder, together with dilatation and effusion in the renal pelvis and ureter (Figures 1-3). Cystoscopy showed extensive congestion, edema, and erosion in the bladder epithelium.
case_images: HE staining based on a urothelial biopsy specimen and IHC for HER2 expression in the urinary tract. (A, B) Slight thinning or even loss in the epithelial cell layer of the urinary tract. (C, D) IHC indicated slight thinning or loss of epithelial cells detected by pathological EnVision method staining. a and b represent the transitional cell and inherent layer of connective tissue, respectively. The images were observed under a magnification of x100.
