Kidney biopsy

A procedure in which a small sample of kidney tissue is removed and examined under a microscope. Kidney biopsy is performed to investigate and diagnose serious kidney disorders, such as glomerulonephritis, proteinuria, nephrotic syndrome, and acute kidney failure, or to assess the kidneys’ response to treatment. There are 2 basic techniques: percutaneous needle biopsy, in which a hollow needle is passed through the skin into the kidney under local anaesthesia; and open surgery under general anaesthesia.
