A: Right renal artery (A) dissociation using the RP approach; B: The kidney (K) was thoroughly dissociated and the renal vein (V) was exposed through a good viewpoint from the dorsal to the ventral space; C: Initial tumor (T) exposure around the hilum area and ureter (U) dissociation. The artery, vein, ureter and the pelvis (P) were completely separated from the mass, respectively; D: Part of the mass was resected along its base; E: Residual tumor tissue was gradually aspirated using an aspirator; F: Pre-suture and plugging hemostatic gauzes.
