Combination of core biopsy and fine-needle aspiration increases diagnostic rate for small solid renal tumors.

Our aim was to evaluate the performance of combination of fine-needle aspiration (FNA) and core biopsy (CB) as a method for the diagnosis of small solid renal tumors.Ninety patients with a radiologically detected small solid renal tumor (≤ 4 cm) underwent a biopsy. Patient underwent FNA (FNA group, n=32) or CB (CB group, n=30) or combination of both FNA and CB (combination group, n=28). The diagnostic rate and accuracy of both techniques were...
