Objective: In this study, we aimed to evaluate the presence and thickness of pseudocapsule after partial nephrectomy in renal cell carcinoma (RCC) cases. Materials and Methods: A total of 100 patients who were admitted to our clinic and diagnosed with RCC were included in the study. Histopathological specimens of the patients who underwent partial nephrectomy were re-evaluated retrospectively. Results: The histopathological results revealed pseudocapsule in 87 cases (87%, median thickness: 0.708 mm). Pseudocapsule median thickness was noted respectively 0.483, 0.691, 0.737, 0.954 mm in Fuhrman Grade 0, 1, 2, 3/4 groups (p<0.05). Conclusion: In this study, a statistical significance was found between nuclear grading system and the thickness of pseudocapsule in RCC. We believe that it may be a prognostic factor for RCC in the future.
