After CT scanning (Figure 2), one 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). 2020-04-28 · Two recent retrospective studies have also reported the outcomes of patients with a complex renal cyst who opted to be managed by active surveillance [17, 18]. The average cyst sizes in the two studies were 4.1 cm and 3.5 cm for Bosniak III cysts, and 3.1 cm and 3.8 cm for Bosniak IV lesions, respectively. Kidney cysts can impair kidney function, although many are what are called simple cysts which do not result in health complications.

This system is known as the Bosniak classification. By means of the Bosniak classification, renal cystic lesions can be categorized in increasing order according to risk of malignancy as follows (Table 1): Bosniak category I Lesions classified as category I are simple renal cysts and rep-resent the majority of renal lesions detected by abdominal Cystic renal masses are commonly encountered in clinical practice.

Although the vast majority of these lesions are benign cysts (), a small percentage are malignant.The Bosniak criteria were introduced to allow the use of specific computed tomographic (CT) findings to help separate nonsurgical from surgical cystic masses and guide patient management (). Cystic renal masses are relatively common in daily practice. The Bosniak classification is a time-proven method for the imaging classification and management of these lesions. Knowledge of the pathognomonic features of certain benign Bosniak 2F/3 lesions is important to avoid surgery on these lesions (e.g., localized cystic disease, renal abscess). The Bosniak scoring system is the currently accepted method for classifying renal cysts. It uses contrast-enhanced computed tomography scan data to classify cysts into five stages. Whilst stage I is a simple renal cyst, all other stages are complex cysts with abnormal morphology.
