Renal calculi in patients with renal angiomyolipomas are difficult to treat because of the hemorrhagic potential of these tumors. We describe the case of a 65-year-old man having tuberous sclerosis complex-associated multifocal renal angiomyolipomas with a large renal calculus. The patient presented with left flank dullness and a previous history of spontaneous angiomyolipoma rupture. Intravenous pyelography revealed a 43 × 16 mm calculus in the pelvis and lower calyx of the left kidney. The calculus was successfully removed by retrograde flexible ureterorenoscopy and holmium-YAG lithotripsy. Flexible ureterorenoscopy is an effective, minimally invasive therapy for patients at high risk of renal hemorrhage.
