Figure 2 Contrast computed tomography with arterial and delayed phase. A: Contrast extravasation during the arterial phase at the upper renal cortex, 1.8 cm. Perirenal hematoma was confined within the gerota fascia; B and D: Diffused leakage with no defined margin of extravasation; the red arrow indicates the extravasation site no longer existing in delayed phase; C: Another extravasation at the lower renal cortex, 0.8 cm. The renal stone (circled) showing significant higher HU.

Figure 3 Comparing the image after TAE with residual J-J stent. A: A 1.5-cm pseudoaneurysm at the upper renal artery branch; B: Embolized using two 0.3 cm × 2 cm and two 0.4 × 2 cm microcoils; C: A 0.4-cm pseudoaneurysm at the lower renal artery terminal branch; D: Embolized using two 0.3 cm × 2 cm microcoils with no contrast extravasation in both lesions (point with white arrowheads).
