case_images: The double J was not reserved before surgery, and computed tomography (CT) examination suggested an 8.3 x 4.5 cm complete staghorn stone with a CT value of 1,321 Hu (Figures 1A, 2A). A 2 mm CT scan and KUB on the first postoperative day showed inferior caliceal residue of approximately 1.0 x 0.6 cm and no perirenal exudation or bleeding (Figures 1B, 2B).
