case_images: Abdominal dynamic CT. A well-defined mass with a diameter of 27 mm was seen on the medial dorsal side of the left kidney with a weak contrast effect in the early phase (a) and a progressive increase in contrast effect in the equilibrium phase (b).

case_images: Three months after the initial CT, the mass had increased to 27 mm on CT (Fig. 1a,b); therefore, we diagnosed nonclear RCC cT1aN0M0 (RENAL nephrometry score: 1 + 1 + 1 + p + 2 = 5p).
case_images: 3D reconstruction of the CT scan. The renal tumor (black arrow) is seen on the dorsal of the kidney. The feeding branch (white arrow) entered the tumor directly from the first posterior branch of the renal artery and the ischemic area (yellow area) was identified.

case_images: We could selectively ligate the feeding artery (Fig. 2) without clamping the main renal artery trunk 6 (Only taping was performed in case of bleeding) because we were able to identify the posterior branch supplying the tumor, which had been identified on preoperative imaging using the SYNAPSE VINCENT  (Fujifilm Medical Co. Ltd., Tokyo, Japan) (Fig. 2).
