Clinical presentation of patients with foreign bodies is highly variable. We received a 55-year-old female patient with fever and right flank pain. She was treated previously for kidney stones by percutaneous nephrolithtomy with partial resolution, requiring renal embolization during this procedure because of bleeding. CT evidenced metallic density images localized in kidney and ureter, associated with kidney stones located in lower calix. Semirigid ureteroscopy and retrograde intrarenal surgery were performed, revealing the presence of foreign bodies in both localizations and lower calix stones. Complete removal of foreign bodies and stones was performed. Foreign bodies were found to be embolization coils applied in the previous procedure.
