Abstract Purpose: To compare the relationship between a benign pathology of preoperative parameters of renal masses <7cm (T1) in diameter. Methods: Between January 2007 and June 2016 and applied to radical nephrectomy, nephron sparing surgery for renal masses < 7 cm (T1) were evaluated retrospectively. Age, sex, tumor size, tumor location, laterality, symptomatology, tumor endophytic / exophytic whether or not the tumor cystic / solid whether or not, smoking history and comorbidities were compared in terms of pathology results. Results: A total of 243 patients, 58 (23%) were benign pathology. Female sex (63%) were significantly higher rate of benign pathology (p = 0.004). 60% of patients with benign pathology was observed that 44% of symptomatic patients with malignant pathology (p = 0.033). We found symptomatic benign pathology that 60% of patients and malignant pathology in 44% of patients (p = 0.033). Pain as a symptom was associated with benign pathology (51.7%). 1-2 cm, 2-3 cm, 3-4 cm benign pathology of renal masses rates were 33%, 20%, 12.5%, respectively. In this study; age, tumor size, tumor location, laterality, tumor endophytic / exophytic whether or not the tumor cystic / solid whether or not, smoking history and comorbidities were observed pathological results to impact not significantly. Conclusion: In our study, symptomatic and female sex in small renal masses appeared benign pathology markers. As a result, predictors before surgery may be considered due to the high rate of benign pathology of small renal masses.
