A rare case of unusual migrated foreign bodies in kidney and their successful extraction using retrograde percutaneous nephrostomy

Foreign body ingestion is a common presentation in the emergency room and most cases are without any major symptoms, or go unnoticed and later cause severe complications that can potentially threaten patient life. We report a case of multiple migrated metallic foreign bodies in the right kidney presenting as right renal colic and gross haematuria one year after its accidental ingestion, treated successfully with retrograde percutaneous nephrostomy.
