A computed tomography (CT) revealed severe hydronephrosis in the left kidney and a huge high-density stone formation at the level of the neobladder (approximately 125 mm x 105 mm x 90 mm in size) that rendered the process of emptying of the neobladder difficult (Figure 1A, blue arrow). A renal scan demonstrated poor blood perfusion in the left kidney (GFR 7.7 mL/min) and normal blood perfusion in the right kidney (GFR 48.74 mL/min) (Figure 1B).

The size of the stone was approximately 13 cm x 11.5 cm x 9 cm (Figure 2A, red arrow) and the weight was approximately 903 g (Figure 2B, yellow arrow).
Postoperative abdominal x-ray showing no stones (green arrow).
