A renal cyst is a fluid collection in or on the kidney. There are several types based on the Bosniak classification.

A multivariate Cox proportional hazards model was used to identify predictors of the Bosniak classification change. The malignancy rate of Bosniak III renal cysts was 40% (29/72), which is significantly lower than 90% (18/20) for surgically resected Bosniak IV renal cysts (p < 0.0001). The malignancy rate of Bosniak IIF renal cysts was 38% (3/8), which is not significantly different from the rate of malignancy of Bosniak III renal cysts (p = 1.000). Bosniak 4 cyst – 80-95% risk of cancer, should be surgically removed; 4.
