In present-day surgery, the key to a successful extensive resection of a parenchymal organ is the use of a wide array of medical devices such as modern generators, surgical instruments, and anesthetic equipment. In this regard, water-jet dissectors as a tool for resection of parenchymal organs can take their place in the list of equipment used in pediatric surgery and pediatric oncology in particular, and contribute to improving patient outcomes. Here we present our experience of using water jet dissection in surgery for renal tumors in children. The work is based on the analysis of clinical material of 48 children with kidney tumors. The study was approved by an Independent Ethics Committee and the Scientific Council of the V.F. Voyno-Yasenetsky Scientific and Practical Center of Specialized Medical Care for Children. All diagnoses were confirmed by histological examination. All patients were divided into two groups: the experimental group (n = 19) and the control group (n = 29). In the experimental group (n = 19), the water jet dissection method was employed, while the children in the control group (n = 29) were operated on using standard techniques. The average duration of the surgery was 200 ± 51 minutes in the experimental group and 198 ± 92 minutes in the control group (p = 0.5). The total volume of intraoperative blood loss differed significantly between the groups: 137.3 ± 101 ml in the experimental group, and 268.1 ± 217.5 mL in the controls (p = 0.05). The patients from the experimental group stayed at the intensive care unit for a shorter period of time: 2.2 ± 0.8 days, compared to 3.5 ± 1.0 days (p = 0.04) in the control group. What is more, the children from the experimental group did not develop any complications after the surgery, while in the control group, complications were registered in 17.1 % of patients. The use of water jet surgery for resection led to reduced blood loss during parenchymal transection. The most important result of the use of water jet dissection was a significant reduction in the frequency of intraoperative blood loss, duration of surgery, and postoperative complications (from 17.1 to 0 %).</p></abstract><trans-abstract xml:lang="ru"><p>   Поиск более совершенного и эффективного метода разделения тканей непрерывно продолжается. На современном этапе развития хирургической техники залогом успешного выполнения обширных резекций паренхиматозных органов является использование широкого арсенала медицинской аппаратуры: современных генераторов, хирургического инструментария, анестезиологической аппаратуры. В связи с этим водоструйные диссекторы как инструмент для резекции паренхиматозных органов могут занять свое место в списке оборудования, применяемого в детской хирургии, в частности в детской онкологии, и внести свой вклад в улучшение результатов лечения пациентов. В статье представлен опыт применения метода водоструйной хирургии при операциях по поводу опухолей почек у детей. Работа основана на анализе клинического материала 48 детей с опухолями почек. Исследование одобрено независимым этическим комитетом и утверждено решением ученого совета ГБУЗ «НПЦ спец. мед. помощи детям ДЗМ». Все диагнозы подтверждены данными гистологического исследования. Пациенты были разделены на 2 группы: основную (n = 19) и контрольную (n = 29). У пациентов, вошедших в основную группу (n = 19), применялся метод водоструйной диссекции, у больных группы контроля (n = 29) – традиционный способ. Средняя продолжительность операции в основной группе составила 200 ± 51 мин, в контрольной – 198 ± 92 мин (р = 0,5). Объем общей интраоперационной кровопотери достоверно различался в обеих группах: в основной группе он составил 137,3 ± 101 мл, в контрольной – 268,1 ± 217,5 мл (р = 0,05). В основной группе выявлено сокращение длительности пребывания пациентов в отделении реанимации и интенсивной терапии: среднее время пребывания в основной группе составило 2,2 ± 0,8 дня, в контрольной – 3,5 ± 1,0 дня (р = 0,047). В основной группе осложнений не отмечено ни у одного ребенка. В контрольной группе осложнения зарегистрированы у 17,1 % пациентов. Применение метода водоструйной хирургии при резекции органа позволило сократить объем кровопотери на этапе пересечения паренхимы. Основным результатом применения водоструйной диссекции явилось достоверное сокращение частоты интраоперационной кровопотери, времени операции, послеоперационных осложнений с 17,1 до 0 %.</p></trans-abstract><kwd-group xml:lang="en"><kwd>kidney tumor</kwd><kwd>water jet surgery</kwd><kwd>kidney resections</kwd><kwd>children</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>опухоль почки</kwd><kwd>водоструйная хирургия</kwd><kwd>резекции почек</kwd><kwd>дети</kwd></kwd-group><funding-group><funding-statement xml:lang="en">Not specified</funding-statement><funding-statement xml:lang="ru">Не указан</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
