However, growing evidence suggests that many can be managed by active surveillance. The main objective of this study was to characterize the use of surveillance in the management of complex renal cysts. Bosniak category 2 renal cortical cyst is characterized by minimally complex, a few thin septa and thin calcification. Renal lesions are less than 3 cm and are generally well marginated. It is non-cancerous. 2020-08-27 · Progression and malignancy rates of cysts (Bosniak ≥IIF) over the 11-year period were calculated. The linear-weighted kappa value was 0.69 for all complex cysts.

The rate of progression and regression of Bosniak IIF cysts was 4.6% (7/151) and 3.3% (5/151), respectively. All malignant IIF cysts progressed within 16 months of diagnosis.
