Abstract
- To determine the usefulness of the Bosniak classification of cystic renal masses, the computed tomographic findings of 30 pathologically proven cystic renal masses were reviewed retrospectively. We categorized cystic renal masses utilizing the Bosniak classification without knowledge of the final pathologic diagnosis. There were 10 category I lesions, 3 category II lesions, 6 category III lesions and 11 category IV lesions. All category l and II lesions were benign. All category IV lesions were malignant. Among the 6 category III lesions, 5 were malignant. The other was benign lesion with hemorrhagic renal cyst. We concluded that computed tomography and Bosniak classification are useful in management of cystic renal masses.
