Its most common form – non-muscle invasive bladder cancer – is one of the most expensive for healthcare and requires many resources for diagnosis and treatment.</p><p><bold>Aim. </bold>To evaluate safety and effectiveness of en bloc transurethral resection (eTUBRT) of bladder wall with tumor compared to conventional transurethral resection (cTUBRT) in context of recurrence-free survival and perspectives of widespread implementation in onco-urological practice.</p><p><bold>Materials and methods. </bold>We have performed a search and analysis of Russian and international literature in the PubMed database on “en-bloc resection of bladder cancer” regarding information about recurrence-free survival in patients after eTURBT and cTURBT, intraand perioperative complications, overall survival, disease progression, and different surgical techniques. References in the sources were also analyzed to identify additional potentially relevant studies.</p><p><bold>Results. </bold>The analysis of the data showed that eTURBT is safer in regards to intraand postoperative complications, and it has better long-term oncological outcomes and quality of extracted histological material. Additionally, no significant differences in treatment outcomes with different instruments (monopolar, bipolar electric current, different laser equipment) were discovered.</p><p><bold>Conclusion. </bold>eTURBT has several advantages compared to cTURBT in treatment of non-muscle invasive bladder cancer and is a potential alternative to cTURBT. However, further research is required to evaluate the place and capabilities of eTURBT in the arsenal of an onco-urologist.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold><bold> </bold>Рак мочевого пузыря входит в первую десятку по распространенности онкоурологических заболеваний. Наиболее часто встречаемая его форма – немышечно-инвазивный рак мочевого пузыря – является одним из самых ресурсоемких и дорогостоящих для здравоохранения в плане диагностики и лечения.</p><p><bold>Цель исследования </bold>– оценка безопасности и эффективности трансуретральной резекции (ТУР) стенки мочевого пузыря с опухолью единым блоком (еТУР) по сравнению со стандартной ТУР (сТУР) в отношении показателей безрецидивной выживаемости пациентов, а также перспективы ее широкого внедрения в онкоурологическую практику.</p><p><bold>Материалы</bold><bold> </bold><bold>и методы. </bold>Выполнены поиск и анализ зарубежной и отечественной литературы в базе PubMed по запросу “en-bloc resection of bladder cancer” касательно данных о безрецидивной выживаемости пациентов после еТУР и сТУР, интраи послеоперационных осложнениях, общей выживаемости, прогрессировании заболевания, а также различных техниках операции. Проведен анализ источников литературы для выявления дополнительных потенциально релевантных исследований.</p><p><bold>Результаты.</bold><bold> </bold>Выявлено, что еТУР представляется более безопасной в отношении интраи послеоперационных осложнений, при этом обладает лучшими отдаленными онкологическими результатами и качеством полученного гистологического материала. Значительных различий в результатах лечения при применении различного инструментария (монополярный, биполярный электрический ток, различное лазерное оборудование) не выявлено.</p><p><bold>Заключение.</bold><bold> </bold>При лечении немышечно-инвазивного рака мочевого пузыря еТУР обладает рядом преимуществ перед сТУР и является весьма перспективной альтернативой сТУР. Для оценки места еТУР в арсенале онкоуролога и ее возможностей необходимы дальнейшие исследования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>bladder cancer</kwd><kwd>non-muscule invasive bladder cancer</kwd><kwd>transurethral resection of the bladder tumor</kwd><kwd>en-bloc resection of the bladder tumor</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак мочевого пузыря</kwd><kwd>немышечно-инвазивный рак мочевого пузыря</kwd><kwd>трансуретральная резекция стенки мочевого пузыря с опухолью</kwd><kwd>en-bloc резекция стенки мочевого пузыря с опухолью</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was performed without external funding.</funding-statement><funding-statement xml:lang="ru">Работа выполнена без спонсорской поддержки.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>EAU Guidelines.
