Accuracy and Clinical Role of Fine Needle Percutaneous Biopsy With Computerized Tomography Guidance of Small (Less Than 4.0 Cm) Renal Masses

Fine needle biopsy of small renal masses could select benign lesions for which observation might be an alternative to surgery. The accuracy of fine needle biopsy in identifying histological tumor type was high. However, biopsy was less accurate in evaluating Furhman grade. Biopsy with helical CT guidance could be a key point in tailored management of small solid renal masses and provide important information to those patients harboring renal masses.
