To analyze our own results of the course of early postoperative period in patients who underwent surgical treatment of kidney tumors: partial nephrectomy (PN) and radical nephrectomy (RN) and to identify risk factors for the development of acute kidney injury (AKI).</p><p><bold>Materials and methods</bold>. The study included 399 patients, of which 276 patients (69.17 %) underwent PN, 123 (30.83 %) underwent RN. According  to the clinical stage of the disease, patients in the PN and RN groups were distributed as follows: cT1a – 160 (91.95 %) and 14 (8.05 %), cT1b – 99 (61.11 %) and 63 (38.89 %) and cT2a – 17 (26.98 %) and 46 (73.02 %), respectively. Operations were performed with open (1.0 %), laparoscopic (39.35 %) and robot-assisted (59.65 %) accesses. AKI was evaluated by the changes in serum creatinine and glomerular filtration rate before surgery and 1–3 days after in accordance with KDIGO criteria.</p><p><bold>Results</bold>. The overall incidence of AKI after surgical treatment  for kidney cancer at stages cT1a–cT2a was 27.57 %. The incidence of AKI after RN was 65.04 %, after PN – 11.23 %. At stages cT1a, cT1b, cT2a, after nephron-sparing surgery and radical treatment, this indicator was 9.37; 11.11; 29.41 % and 71.43; 63.49; 65.22 %, respectively. For warm ischemia time below 15 and 20 minutes, AKI incidence did not exceed 8.3 and 13.2 %, respectively. For warm ischemia time &gt;30 min, a dramatic increase in AKI incidence was observed.</p><p><bold>Conclusion</bold>. To preserve kidney function, PN is the operation of choice in surgical treatment of kidney tumors at stages cT1–cT2a. After RN, AKI development was observed 6 times more often than after PN. The following statistically significant predictors of AKI after PN were identified: presence of initial chronic kidney disease in patients, tumor size, operative time above 190 minutes, type of kidney ischemia used, and warm ischemia time above 25 minutes.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> – анализ собственных результатов хирургического лечения опухолей почек (резекции почки (РП) и радикальной нефрэктомии (РНЭ)) в раннем послеоперационном периоде, выделение факторов риска развития острого почечного повреждения (ОПП).</p><p><bold>Материалы и методы</bold>. В исследование были включены 399 пациентов. Из них 276 (69,17 %) пациентам выполнена РП, 123 (30,83 %) – РНЭ. По клинической стадии заболевания пациенты групп РП и РНЭ распределились следующим образом: сТ1а – 160 (91,95 %) и 14 (8,05 %), сТ1b – 99 (61,11 %) и 63 (38,89 %), сТ2a – 17 (26,98 %) и 46 (73,02 %) соответственно.  Операции выполняли открытым (1,0 %), лапароскопическим (39,35 %) и робот-ассистированным (59,65 %) доступами. ОПП оценивали по изменению уровня креатинина сыворотки крови и скорости клубочковой фильтрации до операции и на 1–3-и сутки после нее согласно  критериям  KDIGO.</p><p><bold>Результаты</bold>. Общая частота развития ОПП после хирургического лечения по поводу рака почки стадий сТ1а–сТ2а составила 27,57 %. Частота развития ОПП после РНЭ – 65,04 %, после РП – 11,23 %. При стадиях сТ1а, сТ1b и сТ2а после  органосохраняющего  и  радикального  лечения  этот  показатель  составил  9,37;  11,11;  29,41  и  71,43;  63,49; 65,22 % соответственно. При продолжительности тепловой ишемии менее 15 и 20 мин частота развития ОПП не превышала 8,3 и 13,2 %. При длительности тепловой ишемии почки &gt;30 мин отмечалось резкое увеличение частоты развития ОПП.</p><p><bold>Заключение</bold>.  В целях сохранения функции почек РП является операцией выбора при лечении опухолей почек стадий сТ1–сТ2а. После РНЭ развитие ОПП фиксировалось в 6 раз чаще, чем после органосохраняющей операции. Установлены факторы, статистически значимо влияющие на развитие ОПП после РП: наличие исходной хронической болезни почек у пациентов, размер новообразования, продолжительность операции &gt;190 мин, вариант используемой ишемии почки и продолжительность тепловой ишемии &gt;25 мин.</p></trans-abstract><kwd-group xml:lang="en"><kwd>kidney cancer</kwd><kwd>partial nephrectomy</kwd><kwd>radical nephrectomy</kwd><kwd>acute kidney injury</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак почки</kwd><kwd>резекция почки</kwd><kwd>радикальная нефрэктомия</kwd><kwd>острое почечное повреждение</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">Axel E.M., Matveev V.B.
