Preoperative computed tomography confirmed the diagnosis and found a source of hydronephrosis – obstruction of the pyeloureteral segment. At laparoscopy, the horseshoe kidney anatomy was finally defined and the cause of the obstruction of the pyeloureteral segment was found too - high ureteral transposition from the pelvis or an aberrant vessel. Pyeloplasty performed by Anderson-Hynes technique was a final stage of the treatment.</p> <p><bold>Results.</bold> The lesion of the left kidney half was noted in 2 cases, of the right one – in 1 case. All three interventions were successfully performed laparoscopically without conversion to open surgery. Duration of surgical intervention varied from 60 to 90 minutes. Mean operative time was 75.0±15.0 min (median – 75.0 [67.5; 82.5] min). Average stay in ICU was 19.3±4.2 hours (median – 18.0 [17.0; 21.0] hours) with the longest interval being 24 hours in a younger patient due to tracheal decannulation problems .</p> <p>The anteroposterior diameter of the pelvis was measured before surgery and 6 months after surgery. It was found that all patients had reduction in the pelvis size in average from 43.3±11.5 mm to 8.0±2.0 mm (median – 50.0 [40.0; 50.0] mm and 8.0 [7.0; 9.0] mm, respectively). Patients also showed a positive trend in the restoration of blood flow in the affected segment of the kidney. Resistance index changes were in averaged from 0.70±0.02 to 0.62±0.02 (median – 0.71 [0.70; 0.72] and 0.62 [0.61; 0.63], respectively).</p> <p><bold>Conclusion. </bold>Surgical treatment of hydronephrosis in patients with the horseshoe kidney is a complex problem, mainly because of the altered renal anatomy and variety of triggers that may cause hydronephrosis. Laparoscopic pyeloplasty is obviously a universal way to treat the discussed pathology.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>Научное исследование представляет собой описание серии клинических случаев лапароскопического лечения обструкции пиелоуретерального сегмента у 3 детей с подковообразной почкой (ПОП).</p> <p><bold>Материал и методы. </bold>Лапароскопическое лечение гидронефроза у пациентов с подковообразной почкой было выполнено одним хирургом у 3 детей (мальчики – 2, девочки – 1). Предоперационная компьютерная томография подтвердила диагноз и обнаружила обструкцию пиелоуретерального сегмента как источника гидронефроза. Лапароскопия окончательно установила анатомию подковообразной почки и причину обструкции пиелоуретерального сегмента в виде высокого отхождения мочеточника от лоханки или аберрантного сосуда. В качестве окончательного метода лечения использовали пиелопластику, выполненную по методике Anderson–Hynes.</p> <p>Поражение левой половины отмечено в 2 случаях, правой – в 1. Все 3 процедуры были выполнены успешно лапароскопическим способом без конверсии в открытую операцию. Продолжительность хирургического вмешательства варьировала от 60 до 90 мин. Среднее время операции составило 75,0 ± 15,0 (медиана (Ме) – 75,0 [67,5; 82,5]) мин. Средняя продолжительность пребывания в палате интенсивной терапии составила 19,3 ± 4,2 (Ме – 18,0 [17,0; 21,0]) ч, с самым длинным интервалом 24 ч у пациента младшего возраста из-за проблем с деканюляцией трахеи.</p> <p>Переднезадний диаметр лоханки был измерен до операции и через 6 мес после выполненного хирургического вмешательства. Установлено, что у всех пациентов достигнуто уменьшение размером лоханки в среднем с 43,3 ± 11,5 до 8,0 ± 2,0 мм (Ме – 50,0 [40,0; 50,0] мм и 8,0 [7,0; 9,0] мм, соответственно). Пациенты также демонстрировали положительные тренды восстановления кровотока в поражённом сегменте ПОП. Изменение индекса резистентности (ИР) составило в среднем от 0,70 ± 0,02 до 0,62 ± 0,02 (медианы – 0,71 [0,70; 0,72] и 0,62 [0,61; 0,63], соответственно).</p> <p><bold>Заключение. </bold>Хирургическое лечение гидронефроза у пациентов с подковообразной почкой представляет собой сложную проблему. В основном, это связано с изменённой почечной анатомией и разнообразием причин, вызывающих гидронефроз. Очевидно, что лапароскопическая пиелопластика является универсальным способом лечения этого состояния.</p></trans-abstract><kwd-group xml:lang="en"><kwd>horseshoe kidney</kwd><kwd>hydronephrosis</kwd><kwd>pyeloplasty</kwd><kwd>laparoscopy</kwd><kwd>children</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>подковообразная почка</kwd><kwd>гидронефроз</kwd><kwd>пиелопластика</kwd><kwd>лапароскопия</kwd><kwd>дети</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ram A.D., Thomas R.E., Malone P.
