One of the factors influencing the long-term results of treatment for this pathology may be the quality of TUR, which depends on a surgeon’s experience.<bold/></p><p><bold>Objective:</bold> to evaluate the impact of a surgeon on relapse-free survival rates after radical treatment in patients with NMIBC and to search the optimal quality criteria for TUR in this disease.<bold/></p><p><bold>Materials and methods.</bold> The data of patients with primary or recurrent NMIBC treated using TUR with and without intravesical therapy at the N. N. Aleksandrov Republican Research and Practical Center for Oncology and Medical Radiology in 2004 to 2013 were retrospectively analyzed. The investigation included a total of 949 cases of performing organ-sparing treatment in 784 patients. The operations were made by 5 surgeons with comparable experience with TUR.<bold/></p><p><bold>Results.</bold> At a median follow-up of 64.3 (3–124) months, the 5-year relapse-free survival rates in 5 surgical groups were 62.9 (95 % confidence interval (CI) 56.2–69.7), 53.6 (95 % CI 47.4–59.9), 51.0 (95 % CI 39.6–62.4), 46.2 (95 % CI 36.4–56.0), and 44.2 % (95 % CI 36.8–51.7), respectively (p &lt; 0.0001). According to the data of multivariate analysis including all potential factors, the prognostic role of a surgeon’s experience retained a high level of statistical significance (p = 0.0013). The differences between the surgeons were less pronounced after resection of tumors at a low risk for recurrence. Analysis of the distribution of the recurrence rates within the first 3, 6, and 12 months after TUR in relation to the surgeon, which were stratified according to recurrence risk groups, showed that the most differing rates were observed 12 months after TUR.</p><p><bold>Conclusion</bold>. An operating surgeon has a significant effect on the risk of recurrence after radical treatment in patients with NMIBC. In our investigation, this effect was observed in spite of the relative much experience with surgical treatment of this disease by all surgeons and the performance of operations in one highly specialized center. The differences between the surgeons are less pronounced after resection of tumors at low recurrence risk. The recurrence rates for primary single (below 10 %), recurrent or multiple (below 19 %), and for recurrent and multiple (below 32 %) tumors within the first year after surgery can be taken for the quality criteria of TUR.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Основной проблемой при лечении рака мочевого пузыря без мышечной инвазии (РМПБМИ) является высокая частота рецидивов после визуально полной трансуретральной резекции (ТУР). Одним из факторов, влияющих на отдаленные результаты лечения этой патологии, может быть качество выполнения ТУР, которое зависит от опыта хирурга.<bold/></p><p><bold>Цель работы</bold> – оценка влияния хирурга на безрецидивную выживаемость после радикального лечения пациентов с РМПБМИ, а также поиск оптимальных критериев качества выполнения ТУР мочевого пузыря при этом заболевании.<bold/></p><p><bold>Материалы и методы.</bold> Проведен ретроспективный анализ данных пациентов с первичным или рецидивным РМПБМИ, леченных с использованием ТУР с или без проведения внутрипузырной терапии на базе РНПЦ ОМР им. Н.Н. Александрова с 2004 по 2013 г. Всего в исследование включены 949 случаев проведения органосохраняющего лечения у 784 пациентов. Операции выполняли 5 хирургов со сравнимым опытом проведения ТУР.<bold/></p><p><bold>Результаты</bold>. При медиане наблюдения 64,3 (3–124) мес показатели 5-летней безрецидивной выживаемости в 5 хирургических группах составили 62,9 (95 % доверительный интервал (ДИ) 56,2–69,7), 53,6 (95 % ДИ 47,4–59,9), 51,0 (95 % ДИ 39,6–62,4), 46,2 (95 % ДИ 36,4–56,0) и 44,2 % (95 % ДИ 36,8–51,7) соответственно (p &lt; 0,0001). По данным мультивариантного анализа с включением всех потенциальных факторов риска сохранялась прогностическая роль опыта хирурга с высокой степенью статистической значимости (р = 0,0013). Различия между хирургами были менее выражены при резекции опухолей с низким риском рецидива. Анализ распределения частоты рецидивов в первые 3, 6 и 12 мес после ТУР в зависимости от хирурга, стратифицированных по группам риска рецидива, показал, что наиболее различающиеся показатели наблюдались через 12 мес после ТУР.<bold/></p><p><bold>Выводы</bold>. Хирург-оператор оказывает существенное влияние на риск рецидива после радикального лечения пациентов с РМПБМИ. В нашем исследовании этот эффект наблюдался несмотря на относительно большой опыт оперативного лечения данной патологии всеми хирургами и выполнение операций в условиях одного высокоспециализированного центра. Различия между хирургами менее выражены при резекции опухолей с низким риском рецидива. За критерии качества выполнения ТУР можно принять частоту рецидивов в течение 1-го года после операции для первичных одиночных опухолей (до 10 %), для рецидивных или множественных опухолей (до 19 %) и для рецидивных и множественных (до 32 %).</p></trans-abstract><kwd-group xml:lang="en"><kwd>non-muscle-invasive bladder cancer</kwd><kwd>transurethral resection</kwd><kwd>quality criteria</kwd><kwd>relapse-free survival rate</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак мочевого пузыря без мышечной инвазии</kwd><kwd>трансуретральная резекция</kwd><kwd>критерии качества</kwd><kwd>безрецидивная выживаемость</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">1.
