Data included; gender, age, hospital stay, living or deceased donor, evidence of acute tubular necrosis, donor (living or cadaver), preference of vessel anastomosis (first artery- second vein; FASV or FVSA), preference of arterial anastomosis (as end-to-end to hypogastric artery or end-to-side to common or external iliac artery), evidence for acute tubular necrosis (ATN), in addition to biochemical variables were noted analyzed by SPSS.</p> <p>Results: With a minimum of 16 and a maximum of 68, the mean±SD was 42,3±13,7 years old. Of the total population studied 52% received kidneys from cadaver donors. Although acute tubular necrosis versus acute rejection was reported at 32% versus 60%, the value of RRI in the total population was 0,76±0,11. There was a significant difference in rejected versus non-rejected (p=0,001) and living versus cadaver donors regarding the values of reported RRI (р=0,018).</p> <p>Conclusion: In this study, the recorded RRI suggested respected information regarding changes within intraparanchymal vascularization linked to rejection after kidney transplantation. Further evidence-based studies regarding RRI with more sample size are recommended.</p></abstract><trans-abstract xml:lang="ru"><p>Введение. Трансплантация почки является наиболее эффективной стратегией снижения риска осложнений и смертности у пациентов с терминальной стадией хронической почечной недостаточности.</p> <p>Цель. Изучить изменения клинических и биохимических показателей, частоту воспалительных осложнений и отторжения трансплантата, а также их взаимосвязь с индексом резистивности почечных артерий.</p> <p>Материалы и методы. Проведено исследование 60 взрослых пациентов после пересадки почки. Оценивались изменения клинических и биохимических параметров, значения индекса резистивности почечных артерий, измеренные при допплерографии, и их связь с развитием отторжения трансплантата. Выполнялся анализ пола, возраста, длительности госпитализации, типа донора (трупный или живой), наличия признаков острого канальцевого некроза, типа сосудистого анастомоза (первая артерия – вторая вена, FASV или FVSA), варианта артериального анастомоза (конец-в-конец с подчревной артерией или конец-в-бок с общей либо наружной подвздошной артерией), а также биохимических показателей. Статистический анализ проводился с использованием программы SPSS.</p> <p>Результаты. Возраст пациентов варьировал от 16 до 68 лет (среднее ± стандартное отклонение – 42,3±13,7 года). Трансплантация от трупного донора была выполнена у 52% пациентов. Частота острого канальцевого некроза составила 32 %, а эпизодов острого отторжения – 60%. Среднее значение индекса резистивности почечных артерий составило 0,76±0,11. Выявлены статистически значимые различия между группами пациентов с отторжением и без него (<italic>p=</italic>0,001), а также между трансплантацией от живых и трупных доноров (<italic>p=</italic>0,018).</p> <p>Выводы. Полученные результаты свидетельствуют, что индекс резистивности почечных артерий является информативным показателем, отражающим изменения кровотока в паренхиме почки, связанные с отторжением трансплантата. Для уточнения его диагностической и прогностической значимости необходимо провести дальнейшие исследования с включением большего числа пациентов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Kidney</kwd><kwd>Transplantation</kwd><kwd>Arterial</kwd><kwd>Resistive Index</kwd><kwd>Rejection</kwd><kwd>Donors</kwd><kwd>Cadaver</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>почка</kwd><kwd>трансплантация</kwd><kwd>индекс резистентности артерий</kwd><kwd>отторжение</kwd><kwd>донор</kwd><kwd>посмертное донорство</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Tantisattamo E, Molnar MZ, Ho BT, Reddy UG, Dafoe DC, Ichii H, Ferrey AJ, Hanna RM, Kalantar-Zadeh K, Amin A.
