ПАЦИЕНТЫ И МЕТОДЫ: проспективное когортное исследование проведено у 81 пациента 65–80 лет. Исследованы ряд демографических, периоперационных, биохимических факторов как возможных значимых предикторов развития острого повреждения почек (ОПП) и снижения СКФ у пожилых пациентов. При использовании регрессионного анализа установлено, что значимыми предикторам развития ОПП являются число пораженных органов, категория диагноза, время операции, концентрация липокалина-2 (NGAL) после операции, продолжительность искусственной вентиляции легких. Значимыми предикторами снижения СКФ являются исходная концентрация креатинина сыворотки крови, индекс массы тела, стадия ОПП (по критериям RIFLE), возраст, время операции и искусственного кровообращения. ЗАКЛЮЧЕНИЕ: на основании полученных данных, используя РБФ – нейронные сети, предложены пригодные модели прогнозирования неблагоприятных ренальных исходов (ОПП и снижения СКФ).</p></abstract><trans-abstract xml:lang="en"><p>AIM OF RESEARCH: Analysis and prognosis of adverse renal outcomes in elderly patients after cardiopulmonary bypass surgery by RBF-neural networks. MATERIALS AND METHODS: a prospective cohort study was performed in 81 patients 65 to 80 years. Investigated a range of demographic, perioperative, biochemical factors as possible significant predictors of acute renal injury and decline of glomerular filtration rate (GFR) in elderly patients avail oneself regression analysis. Set that the significant predictors of AKI are the number of affected organs, the category of diagnosis, the time of surgery, level of lipocaline-2 (NGAL) after cardiac surgery, duration of mechanical ventilation. Significant predictors of GFR decline are the initial concentration of serum creatinine, body mass index, stage of AKI (criteria RIFLE), age, time of surgery and cardiopulmonary bypass. CONCLUSION: based on these data, prediction models of adverse renal outcomes (AKI and decline of GFR) was proposed putting to use the RBF – neural networks.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>острое повреждение почек</kwd><kwd>хроническая болезнь почек</kwd><kwd>предикторы</kwd><kwd>кардиохирургия</kwd><kwd>пожилой возраст</kwd><kwd>нейронные сети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute kidney injury</kwd><kwd>chronic kidney disease</kwd><kwd>predictors</kwd><kwd>cardiac surgery</kwd><kwd>elderly patient</kwd><kwd>neural networks</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Xu JR, Teng J, Fang Y. et al.
