Эндоскопическая коррекция - часто применяемый метод лечения пузырно-мочеточникового рефлюкса у детей.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Изучить точность многомерных математических моделей для прогнозирования исхода однократной эндоскопической коррекции пузырно-мочеточникового рефлюкса декстраномером гиалуроновой кислоты у детей.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование базировалось на результатах эндоскопической коррекции методом STING у 582 пациентов (192 мальчика, 390 девочки) в возрасте от 2 месяцев до 16 лет. Двухсторонний рефлюкс имелся у 201 (34,5%). Общее количество оперированных мочеточников составило 783 из них рефлюкс I степени имелся в 20 случаях, II - в 133, III - в 443 и IV - в 187. Полное удвоение мочеточников обнаружено в 53 наблюдениях. Общая эффективность однократной эндоскопической коррекции составила 53,2%, при ПМР I степени - 90%, II - 82,7%, III - 70% и IV - 37,4%. Для прогнозирования результатов лечения применялась бинарная логистическая регрессия (ЛР) и многослойная искусственная нейронная сеть (ИНС). В качестве предикторов были выбраны возраст, пол, степень рефлюкса, удвоение мочеточников и степень дилатации мочеточника.</p></sec><sec><title>Результаты</title><p>Результаты. Логистическая регрессия и нейронная сеть показали хорошую точность предикции (площадь под ROC-кривой составила 0,7 и 0,77 соответственно) с чувствительностью и специфичностью моделей 70,7% и 66,3% для ЛР, 85,5% и 65,3% для ИНС. Сохранённые оценки параметров прогнозных моделей использованы для прогноза результатов эндоскопической коррекции декстраномером гиалуроновой кислоты методом STING в двух независимых клиниках. Анализ результатов использования прогностических моделей в независимых клиниках показал хорошее качество предикции как с использованием ЛР (75% и 90% правильного прогноза), так и с применением ИНС (89,7% и 77% правильного прогноза).</p></sec><sec><title>Выводы</title><p>Выводы. Логистическая регрессия и искусственная нейронная сеть являются эффективными методами, адекватно прогнозирующими результаты эндоскопической коррекции. Они могут использоваться в практике при выборе метода лечения пузырно-мочеточникового рефлюкса у детей.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Endoscopic dextranomer/hyaluronic acid copolymer (DxHA) injection is the most commonly used minimally invasive method of surgical treatment of vesicoureteral reflux (VUR) in children.</p></sec><sec><title>Purpose of the study</title><p>Purpose of the study. To estimate the accuracy of logistic prognostic models and artificial neural network for prediction a single endoscopic injection DxHA in VUR.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. We used endoscopic DxHA in 582 patients (783 ureteric units) of all grades reflux (I - 20, II - 133, III - 443, IV - 187), 53 ureters had complete duplication. A total effectiveness of surgery was 53.2%. A binary logistic regression model and an artificial neural network (multilayer perceptron) were created, taking the following as independent variables: grade of reflux, the patient's age and sex, the ureteral duplication and ureteral dilatation index.</p></sec><sec><title>Results</title><p>Results. The univariate logistic regression showed that the selected predictors were strongly related to the outcome of the treatment. Binary logistic regression and neural network developed high accuracy of the predictions, area under ROC-curve was 0,7 for logistic regression model (a sensitivity of 70.7%, and a specificity of 66.3%) and 0.74 for artificial neural network (a sensitivity of 85.5%, a specificity of 65.3%). Synaptic neural network weights and logistic regression parameters were used in a scoring model to predict the outcome of a single endoscopic injection of DxHA in 2 independent hospitals. An outcomes analysis using predictive models in independent clinics showed a good quality of prediction both with the use of logistic regression (75% and 90% of the correct prognosis) and using a neural network (89.7% and 77% of the correct prediction).</p></sec><sec><title>Conclusion</title><p>Conclusion. An artificial neural network and a binary logistic regression model are an effective tool to assist urologists in identifying and applying endoscopic treatments for VUR in children.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>пузырно-мочеточниковый рефлюкс</kwd><kwd>эндоскопическая коррекция</kwd><kwd>искусственная нейронная сеть</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vesicoureteral reflux</kwd><kwd>endoscopic correction</kwd><kwd>neural network</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">Яцык С.П., Буркин А.
