- •The new version of Bosniak subclassification had an important role in defining benign lesions in Bosniak III cysts.•Male gender and Bosniak III-OP were independent risk factors for malignancy detection among Bosniak III cysts.•Higher incidence of benign lesions was detected especially in Bosniak III-WS subcategory, it may be a progressed Bosniak IIF cyst.•In case of resected Bosniak IV cyst, the recent subclassification lost its sensitivity and specificity in benign lesion detection. While, Bosniak IV-AP subcategory was truly malignant lesion. : Identification of benign lesions among higher classes of renal Bosniak cysts who are vulnerable to active surveillance instead of surgical approach is still questionable. We aimed in this study to delineate the efficacy of the new Bosniak v2019 classification in benign lesions identification among those cases in comparison with the final histopathology. : In a retrospective review between 2010 and 2021 for patients diagnosed as higher classes Bosniak renal masses was done. Patients’ demographics and radiological data i.e.: age, gender, and final Bosniak v2019 categorization for class III: (1) Enhancing thick wall/septa > 4 mm (III-WS) & (2) Enhancing irregular wall/septa or convex protrusion with obtuse margins <3 mm (III-OP) and for class IV as: (1) Enhancing nodule or convex protrusion with obtuse margins >4 mm (IV-OP) and (2) Enhancing nodule or convex protrusion with acute margins of any size (IV-AP). : A total of 137 patients were included. Bosniak III was identified in 56 patients. Malignancy was detected in 74.5% of resected masses. Among resected Bosniak III cyst, 46.4% were benign histopathologically. Male gender and Bosniak III-OP were independent risks for malignancy among the resected Bosniak III cysts. Conversely, in resected Bosniak IV renal cysts, only 9 of resected masses were benign. In univariate analysis, male gender, absence of multilocular cyst and endophytic masses were predictors for malignancy in resected Bosniak IV cyst. : The Bosniak subclassification v.2019 can define benign lesions. Bosniak III-OP was an independent risk for malignancy detection among the resected Bosniak III cysts.
