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.
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 biopsy.
Surgical treatment of Page kidney has evolved over time as newer techniques have become more popular. [2] Open surgical procedures such as nephrectomy, which was once the treatment of choice have been replaced by less invasive options such as percutaneous drainage or endoscopic capsulotomy.

The exact area is then located by ultrasound. Local anesthetic infiltration is used to numb the area. Then a needle would pass through to make the puncture on the kidney. Then, urine from the kidney is aspirated and check for its contents. If the urine is clear, dye will be injected to delineate the renal pelvis and renal calyx. If the urine is ...
Microwave ablation: Local treatment with a special catheter that destroys tissue with heat generated by microwaves; Genitourinary [16] Percutaneous nephrostomy or nephroureteral stent placement: Placement of a catheter through the skin, directly into the kidney to drain from the collecting system. This is typically done to treat a downstream ...
Fine-needle aspiration: biopsy with a fine needle trying to obtain tissue diagnosis by examining the tumour cells. Core needle biopsy: similar to fine-needle aspiration, only involving the use of larger needles to excise the tissue. Vacuum-assisted biopsy: similar to core needle aspiration but using vacuum assistance to gather the sample ...
Pleural biopsy Closed (percutaneous) (needle) biopsy of mediastinum Open mediastinal biopsy Biopsy of diaphragm Other diagnostic procedures on chest wall, pleura, and diaphragm Other diagnostic procedures on mediastinum Excision or destruction of lesion or tissue of mediastinum
With a small 1 centimeter incision in the loin, the percutaneous nephrolithotomy (PCN) needle is passed into the pelvis of the kidney. The position of the needle is confirmed by fluoroscopy. A guide wire is passed through the needle into the pelvis. The needle is then withdrawn with the guide wire still inside the pelvis.
