Objective: to evaluate the feasibility, safety, and efficacy of cTUR versus thulium laser en bloc resection of bladder tumors using new fiber laser “Urolaz”.</p><p><bold>Materials and methods.</bold> 129 patients, who underwent surgical treatment for BC between 2015–2017 in urological department of I.M. Sechenov First Moscow State Medical University were included in the study. The cTUR were performed for 58 patients, 71 patients underwent thulium laser en bloc resection of bladder tumors.</p><p><bold>Results.</bold> The presence of detrusor muscle in specimen was 58.62 % in cTUR group and 91.55 % in thulium laser en bloc resection group respectively. Obturator nerve reflex, bladder perforation, and bleeding in thulium laser en bloc resection group were absent, therefore immediate instillation of chemotherapy was made in all these cases. Recurrence rate after 12 and 18 months after surgery in the group of en bloc resection was statistically lower compared to the cTUR group.</p><p><bold>Conclusion.</bold> The results, obtained in our study shows that thulium en bloc resection using thulium fiber laser “Urolaz” is feasible, effective and safe procedure for patients with BC. Thulium en bloc resection has a number of advantages over the cTUR: absence of obturator nerve reflex, high quality of specimen for pathological examination (presence of detrusor muscle in specimen was 91.55 %) and low recurrence rate.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Высокая частота рецидивирования рака мочевого пузыря (РМП) после традиционной трансуретральной резекции (ТУР) заставляет вести поиски более эффективных методов оперативного лечения.</p><p><bold>Цель исследования</bold> – оценка выполнимости, эффективности и безопасности резекции стенки мочевого пузыря с опухолью единым блоком (en bloc) с использованием тулиевого волоконного лазера «Уролаз».</p><p><bold>Материалы и методы.</bold> В НИИ уронефрологии и репродуктивного здоровья человека Первого МГМУ им. И. М. Сеченова за период 2015–2017 гг. были прооперированы 129 пациентов по поводу мышечно-неинвазивного РМП. ТУР выполнена 58 пациентам, лазерная тулиевая резекция en bloc – 71 пациенту.</p><p><bold>Результаты.</bold> Клетки мышечного слоя в макропрепарате были представлены в 58,62 % наблюдений в группе ТУР и в 91,55 % случаев в группе лазерной резекции en bloc. Обтураторный рефлекс и связанные с ним перфорации и кровотечения в группе лазерной тулиевой резекции en bloc отсутствовали, благодаря чему всем пациентам данной группы была выполнена немедленная инстилляция химиопрепарата. Частота развития рецидивов через 12 и 18 мес после операции в группе резекции en bloc оказалась статистически значимо ниже по сравнению с группой ТУР.</p><p><bold>Заключение.</bold> Полученные результаты показывают, что тулиевая резекция en bloc с помощью волоконного лазера «Уролаз» выполнима, эффективна и безопасна в рамках лечения пациентов с РМП без инвазии в мышечный слой и имеет ряд преимуществ перед ТУР, а именно отсутствие обтураторного рефлекса, качественный материал для патоморфологического исследования (присутствие клеток мышечного слоя до 91,55 %), низкая частота развития рецидивов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>non-invasive bladder cancer</kwd><kwd>urothelial carcinoma</kwd><kwd>transurethral resection of bladder tumor</kwd><kwd>thulium laser</kwd><kwd>en bloc resection</kwd><kwd>“Urolaz”</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>неинвазивный рак мочевого пузыря</kwd><kwd>уротелиальная карцинома</kwd><kwd>трансуретральная резекция мочевого пузыря</kwd><kwd>тулиевый лазер</kwd><kwd>резекция единым блоком</kwd><kwd>«Уролаз»</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Antoni S., Ferlay J., Soerjomataram I. et al.
