Выявлено, что вторичный пиелонефрит наиболее часто развивается на фоне нейрогенной дисфункции мочевого пузыря и пузырно-мочеточникового рефлюкса. При этом у детей чаще регистрировалась нейрогенная дисфункция мочевого пузыря по гипорефлекторному типу. А среди детей с пузырно-мочеточниковым рефлюксом чаще отмечалось преобладание пузырно-мочеточникового рефлюкса слева. Основным осложнением вторичного пиелонефрита является рефлюкс-нефропатия с развитием хронической почечной недостаточности. За последнее время понятие об обструкции мочевых путей претерпело существенные изменения и стало более емким.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of the study of the etiological, clinical features of secondary pyelonephritis in children, depending on the type of abnormalities of kidney and urinary tract development. We’ve revealed that secondary pyelonephritis most often develops against the background of neurogenic dysfunction of the bladder and vesicoureteral reflux. In this case, children more often recorded neurogenic dysfunction of the bladder in a hyporeflective type. And among children with vesicoureteral reflux, the prevalence of vesicoureteral reflux on the left was more often noted. The main complication of secondary pyelonephritis is reflux-nephropathy with the development of chronic renal failure. Recently, the concept of obstruction of the urinary tract has undergone significant changes and has become more capacious.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>инфекция мочевой системы</kwd><kwd>вторичный пиелонефрит</kwd><kwd>пороки развития</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>infection of the urinary system</kwd><kwd>secondary pyelonephritis</kwd><kwd>malformations</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">Вялкова А.А.
