case_images: Abdominal computed tomography (CT) revealed a 140 mm2 stone in the left renal pelvis with 1500 Hounsfield Units (a); thickening of the urothelium surrounding the stone was suspected after contrast infusion (b) and confirmed in the excretory phase (c).

case_images: Abdominal computed tomography (CT) revealed a 140 mm2 stone in the left renal pelvis with 1500 Hounsfield Units (Figure 1a); thickening of the urothelium surrounding the stone was suspected after contrast infusion (Figure 1b) and confirmed in the excretory phase (Figure 1c).
case_images: Diagnostic CT scan showed no residual stones (a); nonetheless, significant thickening of the urothelium with hyperdense material indicative of blood clots in the collecting system (125 HU; b) and urinary extravasation to the retroperitoneal space through the puncture site (c) were seen.
