Objective: We've investigated the incidence of renal oncocytoma in patients with renal tumour who underwent surgery and the location of imaging for indication of fine needle aspiration biopsy in diagnosis. Material and Methods: 420 patients who underwent radical nephrectomy or nephron sparing surgery between 2005 and 2011 in our hospital were evaluated retrospectively. Patients who diagnosed renal oncocytoma were determined in terms of presence of symptoms and radiological signs, treatment modalities and applicability of fine needle aspiration biopsy or renal biopsy. Results: The incidence of renal oncocytoma was 2.8% and in 7 patients 58% who diagnosed renal oncocytoma had radiological signs. 8 patients 67% were symptomatic at the time of diagnosis. 2 patients 17% were treated with radical nephrectomy while 10 patients 83% with nephron sparing surgery. The incidence of renal oncocytoma was consistent with the literature. We believe that performing fine needle aspiration biopsy or renal biopsy in patients who have radiological signs or difficulty in differentiation between benign and malignant will prevent unnecessary radical surgeries
