Abstract:
Objective To analyze the relationship between the relevant imaging signs of the Bosniak classification system version 2019 and the benign or malignant of cystic renal masses(CRMs).Methods The CRMs were graded using the Bosniak classification system version 2019,and the overall inter-observer agreement,and the agreement between different subgroups were compared.In addition,the diagnostic value of benign and malignant lesions with weighted weakened imaging signs,redefined and quantified imaging signs in the Bosniak classification system after upgrading from version 2005 to version 2019 was analyzed.Results Fifty-six CRMs were enrolled,including 43 benign and 13 malignant lesions.Based on the Bosniak classification system version 2019,the overall inter-observer agreement was excellent(Kappa=0.881),while the agreement of ≤30 mm and MRI were moderate(Kappa=0.548,0.722).In the comparison of the differences between benign and malignant CRMs,there were significant differences between the groups in age,lesion maximum diameter,thick septa or cyst wall,number of septa ≥4,mural nodule,and enhancement(P＜0.05).In the logistic regression model,the mural nodule was the only imaging sign that was significantly correlated with the malignant CRMs[odds ratio(OR)=9.842,P=0.022].Conclusion The Bosniak classification system version 2019 has an excellent overall inter-observer agreement.When the lesions are small,MRI can provide more imaging details.The mural nodule is an independent risk factor for malignant CRMs.
