Also known as: renal biopsy
A kidney biopsy, medically termed a renal biopsy, is a diagnostic procedure that involves the collection of small samples of kidney tissue for microscopic examination. These tissue samples are scrutinized for abnormal deposits, signs of infection, and scarring under a microscope. Kidney biopsies serve multiple purposes, including the diagnosis of kidney cancer, identification of various kidney disorders, and the determination of appropriate treatment plans. In the case of kidney transplant recipients, this procedure is also used to assess the presence of rejection signs. Typically, kidney biopsies are conducted within a hospital setting, with the patient receiving either local or general anesthesia.
The kidney biopsy procedure generally lasts approximately one hour. Throughout this time, the physician locates the kidneys, ensures cleanliness of the area, administers anesthesia, and collects tissue samples. Following the biopsy, the tissue samples are sent to a laboratory where they are meticulously examined under microscopes, and, if necessary, special dyes are used to detect specific substances. Results from a kidney biopsy are usually available within a few days.
