“…This prevalence was lower than recent reports in Sudan, where it ranged from 20 to 30%, as found by Mustafa et al (2016) and Salih et al (2018) [ 32 , 33 ]. Additionally, it was lower than previous reports worldwide which varied from 31 to 59.6% [ 34 – 37 ]. The study excluded a group of patients who cannot undergo Abdominal CT with contrast, this might have resulted in this lower rate of renal arteries variation, as many previous studies including those conducted in Sudan recruited cadaveric dissection for the detection of renal artery variations [ 32 , 33 ].…”

“…Early dividing renal arteries however, were found in 5% of the Sudanese subjects. Comparable to the reported prevalence in other populations which ranged between 6.5% in dd [ 40 ] and Sudanese [ 33 ] to 20.2% in Indians [ 37 ].…”

“…Accessory renal arteries were present in 6% of study population Previous local reports indicated that the prevalence of accessory renal arteries in Sudanese population ranged from 20 to 25% [ 32 , 33 ]. Although the frequency reportedly varies among different populations, ranging from 4% of Malaysian patients to 61.5% of Brazilian patients [ 38 ], consensus with recent reports emphasizes that they are the most common renal artery variation [ 37 , 39 ]. Early dividing renal arteries however, were found in 5% of the Sudanese subjects.…”

Background Renal artery variations are clinically significant due to their implications for surgical procedures and renal function. However, data on these variations in Sudanese populations are limited. This study aimed to determine the prevalence and characteristics of renal artery variations in a Sudanese population. Methods A cross-sectional retrospective study was conducted in Khartoum state from October 2017 to October 2020. A total of 400 Sudanese participants who underwent abdominal CT scans were included. Data on demographic characteristics, kidney measurements, and renal vasculature were collected and analyzed using descriptive statistics and inferential tests. Results The mean age of participants was 46.7 ± 18 years, with a nearly equal gender distribution. Overall, renal artery variations were present in 11% of participants, with accessory renal arteries observed in 6% of the study population. Among those with accessory vessels, 50% were on the right side, 29.2% on the left, and 20.8% bilateral, distributed across hilar 29.2%, lower polar 29.2%, and upper polar 41.7% regions. No significant associations were found between accessory renal arteries and age or gender (p-value > 0.05). However, participants with accessory renal arteries exhibited significantly narrower width 5.0 ± 1.4 than those with no with accessory renal arteries 5.8 ± 1.1 (p-value 0.002) Early dividing renal arteries were found in 5% of participants, with nearly half being bilateral. No significant associations were found between the presence of early dividing renal arteries and demographic or renal measurements (p-value > 0.05). Conclusion This study provides valuable insights into the prevalence and characteristics of renal artery variations in a Sudanese population. The findings contribute to our understanding of renal anatomy in this demographic and can inform clinical practice and surgical planning, particularly in renal transplantation and other renal procedures.

“…[7,26,27] Eliminating discrepancies between the diameters of the vessels with fish-mouth anastomosis of SPA to the main arterial graft, we reduced upper pole infarction risks. [10,27,28] Optimal exposure provided by exvivo reconstruction not only minimised technical errors involved with multiple in situ anastomoses of relatively small vessels on atherosclerotic common or external iliac arteries [7,8,26] but also avoided obstructions by the atherosclerotic plaques during the multiple anastomoses and by doing so prevented their kinking. [25] Back-table reconstruction shortening the WIT lowered the risk of kidney damage.…”

Due to the severe shortage of organs for transplantation, new surgical techniques have been designed for bench or in-situ reconstruction to use all compatible organs that may have been discarded for anatomical arterial variations, as is the case for Multiple Renal (MRA) grafts. [1][2][3] We highlight in our case the transplant of a brain-dead donor's MRA kidney, with four arteries and two veins, in a patient presenting bilateral severe atheromatous iliac arteries, using an innovative reconstruction vascular technique of the donor's iliac artery as a common stem for the four renal arteries.
