However, with a recent increase in the detection of small renal masses because of the widespread use of abdominal computed tomography (CT), there is an increasing role for percutaneous biopsy in the management of renal masses. Percutaneous biopsy of renal masses is indicated to differentiate between a primary renal cell carcinoma and metastatic disease in patients with a known extrarenal primary.

Complications of percutaneous biopsy include bleeding, pneumothorax, and tumor seeding along the needle tract; fortunately, these complications are uncommon. We will review the indications, techniques, complications, sensitivity, and accuracy of CT and ultrasound-guided biopsy of renal masses.
