Отсутствие своевременного лечения может приводить к гибели почечной паренхимы. Одной из причин данного состояния может являться воздействие липосаркомы забрюшинного пространства. В статье приводится клиническое наблюдение, в котором отображены особенности развития и возможности оперативного лечения данного состояния. Особое внимание уделяется рассмотрению различных оперативных подходов. Сравнительный анализ различных методик показывает, что лапароскопическая нефрэктомия и удаление липосаркомы в пределах отрицательного хирургического края резекции, остаётся предпочтительным вариантом, обеспечивающим увеличение продолжительности жизни пациента.</p></abstract><trans-abstract xml:lang="en"><p>Hydronephrotic transformation can result from external compression of the uretero-pelvic junction by a tumor. Without timely intervention, this may lead to irreversible loss of renal parenchyma. Retroperitoneal liposarcoma is one potential cause of such compression. This article presents a clinical case highlighting the progression of the condition and explores surgical treatment options. Special emphasis is placed on evaluating various operative approaches. Comparative analysis indicates that laparoscopic nephrectomy combined with complete resection of the liposarcoma with negative surgical margins remains the preferred strategy, as it is associated with improved patient survival outcomes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>липосаркома</kwd><kwd>гидронефроз</kwd><kwd>рецидив</kwd><kwd>клинический случай</kwd></kwd-group><kwd-group xml:lang="en"><kwd>liposarcoma</kwd><kwd>hydronephrosis</kwd><kwd>recurrence</kwd><kwd>clinical case</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The study was not sponsored funding/support</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">European association of urology.
