“…It has been noticed more frequent part of stenosis in the formation of renal artery anastomosis with internal iliac artery than in the anastomosis with external iliac artery [24]. Other authors simplify this point of view indicating the effectiveness of anastomosis with internal iliac artery [25] and parity between anastomosis of renal artery with external iliac artery or internal iliac artery [26].…”

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...

“…Because the internal iliac artery is "end-to-end" in construction and the kidney may be positioned in the ideal location inside the iliac bed, this anastomosis has been proven to provide a suitable position for the kidney (33). Unfortunately, the lumen is often out of alignment, which makes anastomosis challenging and complicated.…”

Background: Our objective is to perform a renal graft transplant using multiple arteries where the lower polar artery will indeed be anastomosed to the internal iliac artery end to side following declamping the main arterial supply in terms of ischemia time, diuresis, graft perfusion, and postoperative clinical parameters and investigations. Methods: Fifty live donors underwent vascular anastomosis of the graft auxiliary lower polar artery to recipient internal iliac artery end to side anastomosis with various renal arteries bilaterally, including lower polar artery in chosen kidney. The recipients' intraoperative warm and total ischemia periods, as well as their postoperative incidence of acute tubular necrosis, were assessed (ATN). Diuresis, urinary output, and creatinine levels at 1, 3, and 5 days after surgery, as well as at 2 months afterwards. MRI and Doppler ultrasonography, if necessary. Results: In contrast to warm, the mean total ischemia time was 20.86 minutes. Low incidence of ATN (8%) was controlled and postoperative recovery went without a hitch. Regarding postoperative urine output and serum creatinine level monitoring, clinical and laboratory indicators were satisfactory. Depending on the assessment method, colour Doppler ultrasonography reveals well perfused transplanted grafts with a satisfactory peak systolic velocity ratio in the auxiliary graft artery.

“…In LDRT, inadequate length of donor vessels or other anastomotic difficulties can be circumvented by using recipient vessels such as the IEA, gonadal vein or great saphenous vein to reconstruct the relevant vessels. In the absence of suitable native vessels Polytetrafluoroethylene (PTFE) grafts have also been used successfully in reconstruction of graft vessels [18].…”

Introduction: The presence of multiple renal arteries (MRA) in the donor allograft was once a contraindication to transplantation. Despite concerns about risks, these allografts are being increasingly used to overcome a shortage of renal donors. Objectives: To compare the outcomes of live-donor renal allografts with multiple and single renal arteries (SRA) in terms of overall ischemia times, early and late graft function, and vascular and urological complications. Methods: A prospective, non-randomized cohort study was conducted including all live donor renal transplants done by the Vascular and Transplant
