Технический прогресс и развитие новых технологий привели к расширению показаний для проведения РИРХ. Использование мочеточниковых кожухов при этом не является обязательным, однако существует ряд причин, по которым урологи, как правило, используют кожухи, а именно: многократный и безопасный доступ в почку, снижение внутрипочечного давления, снижение риска повреждения инструмента, снижение риска травматизации стенок мочеточника во время литоэкстракции. В обзоре литературы представлены результаты исследований, показывающих безопасность и эффективность использования мочеточниковых кожухов при РИРХ у пациентов с конкрементами почек до 2 сантиметров. Оценивались такие показатели, как характеристики мочеточниковых кожухов, время оперативного вмешательства, показатель Stone Free Rate, интра- и послеоперационные осложнения, а также влияние кожуха на стенку мочеточника. Написание обзора проводили в соответствии с протоколом PRISMA protocol (http://www.prisma-statement.org) для данного типа исследования (ID-423604). При написании данного обзора мы проанализировали статьи, опубликованные в международных базах данных (Web of Science, PubMed, Google Scholar, Scopus).</p></abstract><trans-abstract xml:lang="en"><p>One of the contemporary methods for treating kidney stones up to 2 cm in size is retrograde intrarenal surgery (RIRS). Advances in technology and the development of new techniques have expanded the indications for RIRS. The use of ureteral access sheaths is not mandatory; however, there are several reasons why urologists commonly employ them, including facilitating repeated and safe access to the kidney, reducing intrarenal pressure, minimizing the risk of instrument damage, and decreasing the likelihood of ureteral wall trauma during stone extraction. This literature review presents findings from studies demonstrating the safety and efficacy of ureteral access sheaths in RIRS for patients with kidney stones up to 2 cm. Parameters assessed included characteristics of the ureteral sheaths, operative time, stone-free rate, intra- and postoperative complications, as well as the impact of the sheath on the ureteral wall. The review was conducted in accordance with the PRISMA protocol (http://www.prisma-statement.org) applicable to this type of study (ID-423604). Articles published in international databases such as Web of Science, PubMed, Google Scholar, and Scopus were analyzed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мочеточниковый кожух</kwd><kwd>ретроградная интраренальная хирургия</kwd><kwd>мочекаменная болезнь</kwd><kwd>обзор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ureteral sheaths</kwd><kwd>retrograde intrarenal surgery (RIRS) for stones</kwd><kwd>urolithiasis</kwd><kwd>review</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The study was not sponsored</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">EAU Guidelines.
