Since partial nephrectomy and radical nephrectomy demonstrate comparable oncological safety, nephronsparing surgery is the method of choice in patients with stage T1-T2aN0M0 renal cell carcinoma.</p><p><bold>Objective</bold>: to compare the main perioperative parameters and short-term functional outcomes of treatment for localized stage cT1aN0M0 and cT1b-T2aN0M0 renal cell carcinoma.</p><p><bold>Materials and methods</bold>. A total of 148 laparoscopic partial nephrectomies were performed at N.I. Pirogov City Clinical Hospital No. 1, N.I. Pirogov Russian National Research Medical University between 2016 and 2020. Study participants were divided into two groups. Group 1 included patients with stage cT1aN0M0 tumors (<italic>n</italic> = 89; 60.1 %), whereas group 2 comprised patients with stage T1b-T2aN0M0 tumors (<italic>n</italic> = 59; 39.9 %).</p><p><bold>Results</bold>. The duration of surgery was 120 min (range: 90-150 min) in group 1 and 145 min (range: 120-170 min) in group 2 (<italic>p</italic> = 0.001). The median time of warm ischemia was 13 min (range: 7-17) and 15 min (range: 12-19 min) in groups 1 and 2, respectively (<italic>p</italic> = 0.002). Seven individuals from group 1 (7.9 %) and 12 individuals from group 2 (22.3 %) had their pelvicalyceal system lanced. The median glomerular filtration rate calculated using the MDRD (Modification of Diet in Renal Disease) formula was 56.4 mL/min/1.73 m<sup>2</sup> in group 1 and 54.3 mL/min/1.73 m<sup>2</sup> in group 2 (<italic>p</italic> = 0.252). Three patients in group 1 (3.4 %) had positive resection margin. The median follow-up time was 21 months.</p><p><bold>Conclusion</bold>. Nephron-sparing surgeries are an acceptable option for patients with stage cT1b-T2aN0M0 tumors in terms of their oncological and functional safety. Tumors exceeding 4 cm were associated with an increased risk of disease progression.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. С учетом сопоставимой онкологической безопасности резекции почки и радикальной нефрэктомии органосохраняющее лечение является методом выбора у пациентов с почечно-клеточным раком стадии T1-T2aN0M0.</p><p><bold>Цель исследования</bold> - сравнение основных периоперационных показателей, а также ранних функциональных результатов лечения локализованного рака почки клинических стадий сТ1аN0M0 и сT1b-T2аN0M0.</p><p><bold>Материалы и методы</bold>. С 2016 г. по октябрь 2020 г. включительно в университетской клинике урологии РНИМУ им. Н.И. Пирогова на базе Городской клинической больницы № 1 им. Н.И. Пирогова было выполнено 148 лапароскопических резекций почки. Пациенты были разделены на 2 группы: 1-я - 89 (60,1 %) пациентов со стадией рака сТ1аN0M0; 2-я - 59 (39,9 %) пациентов со стадией сT1b-T2аN0M0.</p><p><bold>Результаты</bold>. Продолжительность операции у пациентов 1-й группы составила 120 (90-150) мин, у пациентов 2-й группы - 145 (120-170) мин (<italic>p</italic> = 0,001). Медиана времени тепловой ишемии в 1-й и 2-й группах составила 13 (7-17) и 15 (12-19) мин (<italic>p</italic> = 0,002), вскрытие чашечно-лоханочной системы наблюдалось в 8 (8,9 %) и 14 (23,7 %) случаях соответственно. Осложнения развились у 7 (7,9 %) пациентов 1-й группы и у 12 (22,3 %) пациентов 2-й группы. Медиана скорости клубочковой фильтрации, рассчитанная по формуле MDRD (Modification of Diet in Renal Disease), в 1-й группе составила 56,4 мл/мин/1,73 м<sup>2</sup>, во 2-й - 54,3 мл/мин/1,73 м<sup>2</sup> (p = 0,252). Положительный хирургический край наблюдался в 3 (3,4 %) случаях в 1-й группе. Медиана времени наблюдения составила 21 мес.</p><p><bold>Заключение</bold>. Выполнение резекции почки у пациентов со стадией почечно-клеточного рака сT1b-T2аN0M0 является допустимым с точки зрения онкологической и функциональной безопасности. Размер опухоли, превышающий 4 см, сопряжен с риском прогрессирования заболевания.</p></trans-abstract><kwd-group xml:lang="en"><kwd>renal cell carcinoma</kwd><kwd>kidney tumor</kwd><kwd>laparoscopic partial nephrectomy</kwd><kwd>nephron-sparing surgery</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>почечно-клеточный рак</kwd><kwd>опухоль почки</kwd><kwd>лапароскопическая резекция почки</kwd><kwd>органосохраняющее лечение</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">State of oncological care in Russia in 2019.
