Renal pseudoaneurysm after rigid ureteroscopic lithotripsy: A case report

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.
