Percutaneous Renal Tumor Biopsy in Small Renal Masses

ABSTRACT

With increased use of abdominal imaging studies, the diagnosis of kidney cancer has shifted toward early diagnoses of renal masses. Most of those tumors are small in sized. Treatment decision making for small renal tumors are challenging clinical problem, especially in elderly and unfit patients. Significant proportion of these small renal masses (SRMs) are benign tumors or low-grade renal cell carcinomas, with relatively indolent biologic and clinical behavior. According to the evidence suggests, percutaneous needle biopsies to clarify the pathological diagnosis of a renal mass as an aid to clinical decision making should be considered more frequently, especially in SRMs.
