The standard of care for both Bosniak III and IV renal cysts is surgical excision, although imaging surveillance is an acceptable management strategy in patients with a short life expectancy or significant comorbidities [ 2 , 3 ]. • The Bosniak system is used to classify cystic renal masses seen on imaging • Only a few studies have correlated cyst classification using the Bosniak system with histological findings after removal of kidneys at surgery. Thus there is a lack of evidence to support the classification’s ability to Se hela listan på journals.lww.com Se hela listan på pubs.rsna.org Smaller (<4 cm) Bosniak III cysts were more likely to be malignant and lesion size should be taken into consideration when considering management of complex cysts. Active surveillance may be a reasonable option for Bosniak III cystic lesions, regardless of overall size, based upon their universal low grade and no patient developing metastatic disease.

Thus, modified Bosniak classification should be used with caution as a guideline tool for the surgeon in decisions if to remove or to follow conservatively children with complex renal cyst. Authors contribution The Bosniak classification of renal cysts introduced in 1986 has proven to be a useful tool in helping to evaluate these lesions and decide clinical management . This classification system has been accepted worldwide as a way of assessing renal lesions, and although interobserver variation occurs in some cases, there is a general agreement in most instances [ 7 - 11 ].
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. The risk of malignancy increases with increasing stage.
