Обследовано 23 пациента с раком ВМП. Всем пациентам выполняли МСКТ с болюсным контрастированием, цитологическое исследование мочи (для выявления атипических клеток или клеток рака). При обнаружении образования ВМП по данным МСКТ пациентам выполняли уретеропиелоскопию с биопсией опухоли. После хирургического вме- шательства проводили гистологическое исследование операционного материала.</p></sec><sec><title>Результаты</title><p>Результаты. Ведущим компьютерно-томографическим признаком рака ВМП является “дефект контрастирования” в экскреторную фазу в чашечно-лоханочной системе (ЧЛС) почки, в мочеточнике. МСКТ позволяет однозначно высказаться в пользу опухолевого процесса в случае накопления образованием контрастного препарата, выявлять образования даже небольших размеров у пациентов без наличия расширения ЧЛС. Систематизированы и сформулированы компьютерно-томографические признаки стадирования злокачественных образований ВМП.</p></sec><sec><title>Выводы</title><p>Выводы. МСКТ является наиболее эффективным методом лучевой диагностики рака ВМП, позволяющим также установить стадию заболевания. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To evaluate the possibility of computed tomography in the diagnostisc and staging of cancer of the upper urinary tract (UUT).</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 23 patients with cancer of the upper urinary tract. All patients underwent contrast-enhanced MSCT, urine cytology (to detect atypical cells or cancer cells). Upon detection of the tumor of UUT according to MSCT, patients underwent ureteropieloscopy with a biopsy. After the surgery was performed to verify the diagnosis histological examination of surgical material.</p></sec><sec><title>Results</title><p>Results. The leading computer-tomographic finding of UUT cancer is a “defect” in renal pyelocaliceal system, in the ureter in the excretory phase. MSCT allows exactly speak about cancer in the case of accumulation of contrast material, can detect even small-sized neoplasm in patients without an extension renal pyelocaliceal system. Systematized and formulated a computer-tomographic signs of staging of malignant tumors of the UUT.</p></sec><sec><title>Conclusion</title><p>Conclusion. MSCT is the most effective diagnostic method of upper urinary tract cancer, and the method allows to establish the stage of disease. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>уротелиальный рак</kwd><kwd>рак верхних мочевых путей</kwd><kwd>компьютерная томография</kwd><kwd>лучевая диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>urothelial tumors</kwd><kwd>upper urinary tract urothelial tumors</kwd><kwd>computed tomography</kwd><kwd>X-ray</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">Волкова М.И., Матвеев В.Б., Медведев С.В. и др.
