Objective: Renal tumors are one of the commonest cancer in urinary tract neoplasms. The incidence of renal tumors is increased because of widespread use of radiological imaging. We evaluated the patients who were diagnosed benign renal tumor and compared with malign renal tumors. Materials and Methods: 253 patients were evaluated who underwent radical or partial nephrectomy for renal tumors betwenn 2003 and 2013 years. The patients who were diagnosed non tumoral disease was excluded from the study. The patients were divided into two groups for pathological report, Group 1 was benign renal tumors and Group 2 was malign renal tumors. Results: The patients were between 21 and 89 years and 65% of the patients was men and 35% was women. 52 patients were treated with partial nephrectomy, radical nephrectomy was performed for 199 patients. The mean ages of patients were 59.94±18.46 and 63.06+13.26 years in Gruop 1 and 2. The median tumor sizes were 4.7±1.56 ve 6.6+3.64 cm in group 1 and 2. Benign renal tumors was diagnosed in 18 7.2% patients. 13 patients 5.2% were oncocytoma, 4 patients 1.6% were anjiomyolipom, and 1patient 0.4% was fibroma. 218 patients 87.5% were diagnosed of renal cell carcinoma. Squamosa cell carcinoma and transitional cell carcinoma were reported in 1 patient 0.4% and in12 patients 4.8% .Conclusion: Diagnosis of benign renal tumors is usually seen in patients who underwent nephrectomy for diagnosis of renal tumors preoperatively. Improvement of radiologic techniques for preoperative diagnosis might be related without necessity of nephrectomy in benign renal tumors
