case_images: Figure 1 ). For the treatment, the patient underwent robot-assisted laparoscopic left partial nephrectomy and 3 months after first surgery underwent laparoscopic partial right nephrectomy. The red and white cell counts and the renal function index were in the normal range during and after the treatment ( Figure 3  and  Supplementary Image 1 ).
case_images: Pathological section (H&E, x100). (A, B): Hematoxylin-eosin staining showed that the cytoplasm of renal cell carcinoma was eosinophilic and had a tubular and glandular structure.

case_images: CT after surgery. (A-D): Third month after surgery, (E-H): 6 months after surgery, (I-L): 24th month after surgery. The margins of the upper left kidney (A, B, E, F, I, J) and lower right kidney (C, D, G, H, K, L) were irregular. The perirenal space of the bilateral kidneys was clear, and the shape and size were normal. There was no obvious enlarged lymph node shadow in the retroperitoneum. (A, E, I): Plain scan stage. (B, F, J): Cortical stage. (C, G, K): parenchymal stage. (D, H, L): Renal pelvis stage. The white arrow indicates status of partial nephrectomy.
