Various studies have shown that this technology is feasible and safe in most pediatric patients.</p> <p>The authors of this study conducted a retrospective review of the medical history of a child with a doubling of the upper urinary tract, accompanied by obstructive damage to the upper segment of the ureter with loss of its excretory function. The data collection included the patient's medical history and demographic data, diagnosis, type of surgery, total time of surgery, outcome of surgery, and the anatomical and functional state of the kidney during follow-up.</p> <p>A 12-year-old girl presented to the surgical department with complaints of recurrent urinary tract infections and right flank pain for the last year of her life. Robot-assisted laparoscopic heminephrectomy (RALHN) was performed using the Versius surgical robot. The upper segment ureter was transected at the lower pole of the kidney. The afunctional portion of the kidney was dissected from the normal kidney using a bipolar coagulation clamp. The lower segment incision edges were left open. The distal ureter was then isolated and sealed with a clip. The robot-assisted laparoscopic heminephrectomy procedure was successfully performed without intraoperative complications. The surgery duration was 225 minutes, including 20 minutes for robotic insertion. The total console time was 205 minutes. The drainage tube was removed after a follow-up ultrasound examination on the second day. The stent remained in the lower segment ureter until its removal six weeks after surgery. A repeat ultrasound examination performed postoperatively demonstrated no dilation of the lower segment pelvis or fluid collections in the area of the right kidney. Blood flow to the residual segment of the right kidney was not impaired.</p> <p>The advantages of the robotic approach to treating upper urinary tract duplication, including improved instrument maneuverability and 3D visualization, make it a safe and effective alternative to open or laparoscopic surgery in children.</p></abstract><trans-abstract xml:lang="ru"><p>Роботассистированная хирургия ― относительно новая технология, позволяющая выполнять широкий спектр урологических процедур с использованием минимально инвазивного подхода. Различные исследования показали, что использование этой технологии возможно и безопасно в большинстве случаев в детской популяции.</p> <p>Авторы настоящего исследования проанализировали историю болезни ребёнка с удвоением верхних мочевых путей, сопровождающимся обструктивным поражением мочеточника верхнего сегмента с потерей его выделительной функции. Сбор данных включал анамнез болезни пациентки и демографические данные, диагноз, тип хирургического вмешательства, общее время операции, исход операции и анатомо-функциональное состояние почки при последующем наблюдении.</p> <p>Девочка в возрасте 12 лет поступила в хирургическое отделение с жалобами на рецидивирующие инфекции мочевыводящих путей и боль в правом боку на протяжении последнего года жизни. Роботассистированную лапароскопическую геминефрэктомию (RALHN) выполняли с помощью хирургической системы нового поколения Versius. Мочеточник верхнего сегмента пересекали у нижнего полюса почки. Афункциональную часть почки отсекали от нормальной с помощью биполярного коагуляционного зажима. Края разреза нижнего сегмента оставляли открытыми. Затем выделяли дистальную часть мочеточника и герметизировали клипсой. Процедура RALHN была выполнена удачно без интраоперационных трудностей и осложнений. Продолжительность операции составила 225 минут, из них длительность инсталляции робота (время докинга) ― 20 минут, основное консольное время ― 205 минут. Дренажная трубка была удалена на вторые сутки после контрольного ультразвукового исследования. Стент оставался в мочеточнике нижнего сегмента до его удаления через 6 недель после операции. Повторное ультразвуковое исследование, выполненное после операции, продемонстрировало отсутствие расширения лоханки нижнего сегмента, а также скопления жидкости в области правой почки. Кровоток в остаточном сегменте правой почки не нарушен.</p> <p>Преимущества, обеспечиваемые роботическим подходом при лечении удвоения верхних мочевых путей, включая улучшенную манёвренность инструментов и трёхмерную визуализацию, позволяют использовать его в качестве безопасной и эффективной альтернативы открытым или лапароскопическим операциям у детей.</p></trans-abstract><kwd-group xml:lang="en"><kwd>duplication of the upper urinary tract</kwd><kwd>robot-assisted laparoscopic heminephrectomy</kwd><kwd>RALHN</kwd><kwd>children</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>удвоение верхних мочевых путей</kwd><kwd>роботассистированная геминефрэктомия</kwd><kwd>RALHN</kwd><kwd>дети</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Denning NL, Kallis MP, Prince JM.
