Percutaneous native renal biopsy is recognized as a safe procedure. The majority of bleeding events occur within 24 h after the procedure, and reports of delayed major complications are very limited. We report a patient presenting with sudden flank pain 7 days after renal biopsy, in whom abdominal computed tomography showed increased hematoma size with extravasation and who was treated with radiological intervention. Careful attention should be paid to diagnose and treat delayed major complications in patients undergoing native renal biopsy.
