Пиелопластика у детей обеспечивает успех в 83 – 97% случаях. Однако на сегодняшний день отсутствует консенсус в части определения понятия «успех» в отношении результатов пиелопластики, что исключает формирование общепринятого стандартизированного подхода к послеоперационному ведению пациентов. Цель исследования. Исследовать динамику регрессии дилатации чашечно-лоханочной системы (ЧЛС) у пациентов с обструкцией пиелоуретерльного сегмента (ОПУС) после пиелопластики.Материалы и методы. Исследована динамика регрессии дилатации ЧЛС у 69 пациентов с ОПУС после пиелопластики. Внутренняя причина ОПУС установлена у 55 (80%) пациентов, внешняя причина (конфликтный сосуд) — у 14 (20%) больных. Больные оперированы с использованием лапароскопического доступа, редукционную резекцию лоханки не выполняли. В до- и послеоперационном периодах УЗИ почек выполняли в положении на животе в состоянии волемического покоя на фоне опорожненного мочевого пузыря. Сравнивали значения ПЗР лоханки, измеренный в сагиттальной плоскости. У всех использовали наружный метод дренирования ЧЛС, который прекращали после восстановления уродинамики верхних мочевыводящих путей (ВМП) по данным пиеломанометрии.Результаты. Через 3 месяца после пиелопластики отмечается регрессия дилатации ЧЛС почки на 40%, через 6 месяцев — на 53%, через 12 месяцев — на 64% от исходного значения. У пациентов с внутренними причинами ОПУС через 3 месяца после пиелопластики отмечается регрессия дилатации ЧЛС почки на 34%, через 6 месяцев — на 42%, через 12 месяцев — на 61%, а у пациентов с внешними причинами ОПУС через 3 месяца отмечается регрессия ЧЛС на 49%, через 6 месяцев — на 56%, через 12 месяцев — на 86%. Заключение. Пред- и послеоперационное УЗИ почек при ОПУС должно выполняться в положении пациента на животе в состоянии волемического покоя на фоне опорожненного мочевого пузыря. У пациентов с уродинамически подтверждённым восстановлением проходимости ПУС через 12 месяцев после операции отмечается уменьшение дилатации ЧЛС на 61% у пациентов с внутренними причинами ОПУС и на 86% у детей с внешними причинами ОПУС от дооперационных значений.</p></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Pediatric pyeloplasty ensures a successful outcome in 83 – 97% cases. However, current lack of consensus regarding the definition of "success" related to results of pyeloplasty prevents development of a generally accepted standardised approach to postoperative care management. Objective. To study the dynamics in regression of renal collecting system (RCS) dilatation in patients with urteropelvic junction obstruction (UPJO) following pyeloplasty. Materials &amp; methods. We have investigated dynamics in regression of RCS dilatation in UPJO-patients following pyeloplasty. An intrinsic UPJO cause was established in 55 (80%) patients, an extrinsic factor (crossing vessel) — in 14 (20%) cases. The patients underwent surgery involving laparoscopic access, no reducing resection of the renal pelvis was performed. In the pre- and postoperative periods, renal ultrasonography was carried out in the prone position without volemic load and with an empty bladder. Pelvic anterior-posterior diameter measured in the sagittal plane were then compared. In all cases, external RCS drainage technique was employed until restoration of urodynamics in the upper urinary tract according to the pyelomanometry data.Results. In 3 months following pyeloplasty, a regression is noted in the RCS dilatation by 40%, after 6 months — by 53%, after 12 months –— by 64% of the initial value. In patients with intrinsic UPJO causes, after 3 months following pyeloplasty a regression is noted in the RCS dilatation by 34%, after 6 months –— by 42%, after 12 months — by 61% of the initial value; in patients with extrinsic PUJO factors, after 3 months the regression noted in RCS dilatation is 49%, after 6 months — 56%, after 12 months — 86%. Conclusion. Pre- and postoperative renal ultrasound in PUJO cases should be performed in the prone position without volemic load and with an empty bladder. In patients with confirmed restoration of UPJ patency after 12 months following surgery, a decrease in the RCS dilatation by 61% is noted among the patients with intrinsic PUJO causes and by 86% from pre-surgery values in children with extrinsic UPJO factors.</p><p> </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гидронефроз</kwd><kwd>обструкция пиелоуретерального сегмента</kwd><kwd>эффективность пиелопластики</kwd><kwd>передне-задний размер лоханки</kwd><kwd>ультразвуковое исследование</kwd><kwd>дети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hydronephrosis</kwd><kwd>ureteropelvic junction obstruction</kwd><kwd>pyeloplasty</kwd><kwd>anterior-posterior pelvic diameter</kwd><kwd>ultrasound</kwd><kwd>children</kwd><kwd>review</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">Lee RS, Cendron M, Kinnamon DD, Nguyen HT.
