OBJECTIVES: To examine radiological growth patterns as an indicator of @entity703 aggressiveness, we studied about the growth kinetics of small renal mass(SRM,  <=4cm) and possible associated factors for high Fuhrman nuclear grade (>= 3). METHODS: From January 1999 to May 2013, 112 cases (111 @entity1 ) diagnosed as @entity1358 after surgical treatment were reviewed retrospectively. @entity1 who had at least two preoperative contrast-enhanced computed tomography scans more than 6 months apart were included. RESULTS: The mean age was 59 years and mean CT follow up duration was 20 months. Median @entity5 size and @entity5 volume at diagnosis were 1.45 cm, 1.80cm(3), respectively. Median linear growth rate (LGR) was 0.28 cm/year. Median volumetric growth rate ( @entity11673 ) was 0.75cm(3)/year and median volume doubling time (VDT) was 1.41 years. @entity5 growth rate was not different to histologic type (p=0.271). High LGR was a significant factor associated with high Fuhrman grade in multivariate analysis (OR 3.877, 95% CI 1.715-8.765). @entity11673 (p<0.001) and VDT (p=0.004) were positive correlation with initial mass size, but not LGR (p=0.764). CONCLUSION: In our growth kinetics study, generally SRM grew slowly. High LGR could be a risk factor for high grade @entity5 (Fuhrman grade >= 3).
