Abstract: Percutaneous renal biopsy is commonly used for diagnosis, prognosis, and management of nephropathies. Complications may arise after renal biopsy, most frequently in the form of bleeding. The majority of bleeding events occur within 24 h after the procedure, and reports of delayed major complications are very limited. Here, we report a patient who developed serious post-procedure bleeding, diagnosed by computed tomography (CT) 7 days after renal biopsy and was successfully treated by angiographic embolization.
