Figure 3 Residual kidney section confirmed by computed tomography angiography and digital subtraction angiography. A and B: The patient's preoperative computed tomography angiography and digital subtraction angiography comparison confirmed that a branch artery (orange triangle) in the lower pole of the right kidney runs out of the contour of the kidney to supply blood to the residual kidney section (orange arrows); C and D: The patient’s preoperative and postoperative computed tomography angiography comparisons confirmed that only the main trunk remained after interventional embolization of the residual renal artery branch.
