WHAT IS KIDNEY BIOPSY TEST?
The surgical or percutaneous needle biopsy is resulting in the aseptic removal of a small quantity of kidney tissue. Before kidney transplantation, a histologic examination of a kidney biopsy specimen is performed to evaluate the extent of glomerulosclerosis, interstitial fibrosis, and vascular damage, which can reduce the long-term survival of the graft. After kidney transplantation, a biopsy of the transplanted kidney can provide evidence of subacute clinical rejection and chronic allograft nephropathy. This procedure is often performed under the guidance of ultrasound or computed tomography but may also be an open (surgical) or a transjugular (transvenous) procedure. In the rare instance of a pelvic kidney,laparoscopy has been used to obtain the biopsy.
