The efficiency of treatment is affected not only by the etiology of the stricture, its length, the technique of the surgical procedure (open, endoscopic, laparoscopic, robot-assisted), but also the method and duration of ureteral drainage in the postoperative period. Classical approach using one internal stent does not provide optimal ureteral lumen at the site of intervention, while special stents for endopyelotomy (with larger segment at the area of stricture) can lead to ischemia and prevent adequate urodynamics. The insertion of two internal stents (tandem stenting) allows to achieve adequate urine passage due to the so-called "useful" space between the stents and the natural ureteral lumen, a low probability of ischemia due to the absence of circular pressure on the stricture area, as well as a sufficient diameter to maintain the internal lumen. In this article, publications devoted to tandem ureteral stenting are reviewed and our own results are presented.</p> <p>Tandem ureteral stenting is an effective and safe method and, in the future, can expand the possibilities of minimally invasive treatment of patients with ureteral strictures.</p></abstract><trans-abstract xml:lang="ru"><p>Стриктура мочеточника является распространенной урологической проблемой и отличается высокой частотой рецидивирования. На эффективность лечения пациентов влияет не только причина возникновения стриктуры, ее протяженность, методика выполняемого оперативного вмешательства (открытое, эндоскопическое, лапароскопическое, работ-ассистированное), но и способ и продолжительность дренирования мочеточника в послеоперационном периоде. Классическое дренирование мочевыводящих путей с помощью одного внутреннего стента не обеспечивает оптимального просвета мочеточника в месте оперативного вмешательства, а специальные эндоуретеропиелотомические стенты (стенты с расширением) могут привести к ишемии в зоне хирургического интереса и препятствовать адекватной уродинамике. Установка двух внутренних стентов ипсилатерально (тандемное стентирование мочеточника) позволяет достичь адекватного пассажа мочи, благодаря так называемому полезному пространству между стентами и естественным просветом мочеточника, низкую вероятность ишемии, обусловленную отсутствием циркулярного давления на область операции, и достаточный диаметр для поддержания внутреннего просвета мочеточника. В данной работе мы анализиурем публикации, посвященные тандемному стентированию мочеточника, и приводим собственные результаты.</p> <p>Тандемное стентирование мочевыводящих путей является эффективным и безопасным методом и в перспективе может расширить возможности малоинвазивного лечения пациентов со стриктурами мочеточника.</p></trans-abstract><kwd-group xml:lang="en"><kwd>internal stenting</kwd><kwd>ureteral stent</kwd><kwd>tandem stenting</kwd><kwd>endoureterotomy</kwd><kwd>endopyelotomy</kwd><kwd>ureteral stricture</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>внутреннее дренирование ВМП</kwd><kwd>мочеточниковый стент</kwd><kwd>тандемное стентирование</kwd><kwd>эндоуретеротомия</kwd><kwd>эндопиелотомия</kwd><kwd>стриктура мочеточника</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Gadzhiev N.K. and coauthors.
