“…Artery stenosis of kidney allograft -is the most widespread vascular complication, which can be observed in the process of kidney transplantation [16]. Stenosis frequency varies within 5-23 % [1,3,[12][13][14]17].…”

“…During ultrasonic examination of kidney allograft the following features of arterial stenosis are determined: pulse wave like "tardus-parvus", peak systolic velocity (PSV) of blood flow in the renal artery >250 cm/s, formation between stenotic and prestenotic segments of velocity gradient >2:1, decreasing the index of resistance (IR) <0.56 [15,18]. Hemodynamic significant stenosis of kidney allograft artery (>70 %, pressure gradient >15 mm of mercury column) more likely leads to the kidney allograft's function violation and has the tendency to the progress with the continuous risk of the transplant loss [1,[12][13][14][15][16][17]. At the same time stenosis can lead to the kidney allograft artery thrombosis [19].…”

“…Thrombosis develops during the first week (the most frequently during the first two-three days) after kidney transplantation [1,3,[12][13][14][15][16]. The risk factor of arterial thrombosis is the use of multiarterial kidney allograft.…”

“…The risk factor of arterial thrombosis is the use of multiarterial kidney allograft. Some errors of surgical technique can lead to the thrombosis: unidentified intimal tear, technique defects of vascular stitch, artery's inflection (if the artery is longer than vein or if there is wrong localization of anastomosis formation) [1,3,[12][13][14][15][16]20]. The lack of arterial and vein blood flow in kidney allograft is determined in the process of Doppler study [15,18].…”

“…The lack of arterial and vein blood flow in kidney allograft is determined in the process of Doppler study [15,18]. Taking into account the lack of collateral vessels and low tolerance for warm ischemia such grafts are necessary to remove in the most cases [1,3,[12][13][14][15][16]20].…”

The adequacy of blood supply in the allograft is one of the main factors of kidney transplant vitality and function and the effectiveness of transplantation itself.The aim of the study was to investigate the effectiveness and variants of arterial reconstructions of kidney allograft. Material and Methods.The results of kidney transplantation were analyzed among 66 patients. During the period from 2012 to 2016, all of them were done kidney transplantation in the department of transplantology. There were 37 (56.1 %) men, 29 women (43.9 %), the average age at the time of surgery was 33.2 ± 12.0 years. According to the aim of the study all the patients were divided into two groups: the first group included 12 (18.2 %) recipients, who received an arterial reconstruction. The age of the patients was 30.8 ± 6.5 years, there were 6 (50 %) men, other -women. Another group involved 54 (81.8 %) patients without arterial reconstruction. The average age of recipients was 33.7 ± 12.9 years, there were 31 (57.4 %) men, 23 women (42.6 %). We analyzed duplex examination of kidney allograft on the 7.6 ± 1.9 day after kidney transplantation. Results.According to the analysis of duplex examination the features of blood disorder in kidney allografts were not determined. The differences between groups were non-significant (p > 0.05). There were not identified any stenosis, thrombosis or bleeding in any cases of arterial reconstructions of kidney allograft; function of kidney allograft has preserved for the period of 2.2 ± 1.4 years. Conclusions.Adequate arterial reconstruction of kidney allograft is effective and safe method of kidney preparation for transplantation. Одним із принципових факторів життєздатності та функції пересадженої нирки, а отже й ефективності трансплантації, є адекватність кровотоку в аллотрансплантаті.Мета роботи -вивчити ефективність і варіанти артеріальних реконструкцій ниркового аллотрансплантату.Матеріали та методи. Проаналізовані результати трансплантації нирки 66 хворим. З 2012 по 2016 р. їм виконана пересадка нирки у відділенні трансплантації. Чоловіків було 37 (56,1 %), жінок -29 (43,9 %), середній вік пацієнтів -33,2 ± 12,0 року. Згідно з метою роботи пацієнтів поділили на групи: першу становили 12 (18,2 %) реципієнтів, яким виконане хірургічне втручання на артеріях трансплантату. Середній вік пацієнтів -30,8 ± 6,5 року, чоловіків було 6 (50 %), інші -жінки; друга група -54 (81,8 %) пацієнти, в яких не було необхідності в артеріальних реконструкціях аллонирки. Середній вік реципієнтів -33,7 ± 12,9 року, чоловіків було 31 (57,4 %), жінок -23 (42,6 %). Аналізували дуплексне сканування ниркового аллотрансплантату в середньому на 7,6 ± 1,9 доби після пересадки нирки.Результати. Під час дуплексного ультразвукового сканування ознак порушення кровотоку в ниркових аллотрансплантатах не виявили. Відмінності між групами статистично невірогідні (p > 0,05). У жодному випадку не зареєстровано стенозів, тромбозів або кровотеч; за період спостереження 2,2 ± 1,4 року функція аллонирок збережена.Висновки. Адекватна артер...

Background: Many centres deny obese patients with a body mass index (BMI) >35 access to kidney transplantation due to increased intraoperative and postoperative complications. Methods: From August 2017 to December 2019, 73 consecutive cases of kidney transplantation in morbidly obese patients were enrolled at a single university at the initiation of a robotic transplant surgery program. Outcomes of patients who underwent robotic assisted kidney transplant (RAKT) were compared to frequencymatched patients undergoing open kidney transplant (OKT).Results: A total of 24 morbidly obese patients successfully underwent RAKT, and 49 obese patients received an OKT. The RAKT group developed fewer surgical site infections (SSI) than the OKT group. Graft function, creatinine, and glomerular filtration rate (GFR) were similar between groups 1 year after surgery. Graft and patient survival were 100% for both groups.Conclusions: RAKT offers a safe alternative for morbidly obese patients, who may otherwise be denied access to OKT.
