Various groups of researchers have carried out meta-analysis based on the results of applying the proposed classification during the time that has passed since the publication of the last version. Taking into account the information received, which revealed a number of limitations and disadvantages of the previously used method for systematizing renal cystic masses, as well as in connection with the development of medical imaging methods, updated diagnostic algorithms were formulated, which served as the basis for the Bosniak 2019 classification. It is expected that the use of Bosniak 2019 will optimize stratification renal lesions of the cystic structure and reduce the number of removed benign tumors, can be used as a basis for the future research to further improve the classification and its congruence with the requirements of clinical specialists.</p></abstract><trans-abstract xml:lang="ru"><p>Классификация кистозных образований почек по данным компьютерной томографии, позволяющая стратифицировать их в зависимости от риска малигнизации, была создана M.A. Bosniak в 1986 г. и модифицирована в 1994 г. За время, прошедшее с момента публикации последней версии, разными группами исследователей неоднократно проводился обобщенный анализ результатов применения предложенной классификации. С учетом полученной информации, выявившей ряд ограничений и недостатков применяемого ранее способа систематизации кистозных образований почек, а также в связи с развитием методов медицинской визуализации были сформулированы обновленные алгоритмы диагностики, послужившие базой для классификации Bosniak 2019. Ожидается, что использование классификации Bosniak 2019 позволит оптимизировать стратификацию очагов кистозной структуры и уменьшить количество удаляемых доброкачественных образований. Классификация Bosniak 2019 может быть применена в качестве основы будущих исследований для дальнейшего усовершенствования классификации и ее конгруэнтности требованиям клинических специалистов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Bosniak classification version 2019</kwd><kwd>cystic renal masses</kwd><kwd>computed tomography</kwd><kwd>magnetic resonance imaging</kwd><kwd>algorithm for the diagnosis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>классификация Bosniak 2019</kwd><kwd>кистозное образование почки</kwd><kwd>компьютерная томография</kwd><kwd>магнитно-резонансная томография</kwd><kwd>алгоритм диагностики</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Bosniak M.A. The current radiological approach to renal cysts.
