Renal biopsy (also kidney biopsy) is a medical procedure in which a small piece of kidney is removed from the body for examination, usually under a microscope. [1] Microscopic examination of the tissue can provide information needed to diagnose, monitor or treat problems of the kidney.
Taken as a whole, if the disease is limited to the kidney, only 20–30% develop metastatic disease after nephrectomy. [110] More specific subsets show a five-year survival rate of around 90–95% for tumors less than 4 cm. For larger tumors confined to the kidney without venous invasion, survival is still relatively good at 80–85%.
An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration ...

Kidney transplant rejection can be classified as cellular rejection or antibody-mediated rejection.

A lot of older people that need kidney transplants get cognitive or neurologic issues after general anesthesia," said Dr. Nadig. Right now, kidney transplants are usually done with a patient fully ...
Rapidly progressive glomerulonephritis - This is a syndrome of the kidney that is characterized by rapid loss of kidney function (usually >50% decline in glomerular filtration rate (GFR) within 3 months) [23] with glomerular crescent formation frequently seen on kidney biopsy.
While abnormalities on urinalysis may continue for a long time, only 1% of all HSP patients develop chronic kidney disease. [8] Hypertension (high blood pressure) may occur. Protein loss and high blood pressure, as well as the features on biopsy of the kidney if performed, may predict progression to advanced kidney disease. Adults are more ...
