“…Our description of four renal arteries supplying one kidney is very rare among the existing reports on the variations of renal arterial supply; it is not, however, the only such description [5,19,20,25,29]. Previous investigators reported many interesting variants of the renal arterial supply.…”

“…Awareness of the many anatomical variants of the renal vascular system is important in the diagnosis of kidney diseases, and it helps understand why some patients have unusual clinical presentations. Knowing the anatomy of the renal vessels is particularly important in kidney transplantation, in which an accurate radiological evaluation of these vessels is essential to plan surgery [5,18,28].…”

“…In the remaining 25% of cases (20% to 30%), at least 2 arteries supply 1 kidney. In ~20% of cases (14% to 23%), the kidney is supplied by 2 renal arteries originating from the abdominal aorta; in ~2.5% of cases (1% to 4%), by 3 renal arteries; and in only < 1% of cases, by 4 renal arteries [5,8,18,29]. The occurrence of additional renal arteries depends on the sex and race [23].…”

Four left renal arteries — a rare variant of kidney arterial supply

et al. 2015

We describe the arterial supply of a human kidney harvested post-mortem from a 75-year-old female volunteer body donor. The kidney was analysed with contrast-enhanced computed tomography, and corrosion casting was used to reveal the kidney's angio-architecture. In the left kidney, we observed four renal arteries, each originating directly from the abdominal aorta. Three renal arteries, including the main renal artery, coursed through the renal hilum, and the fourth renal artery reached the lower kidney pole. The supply areas of each of the four renal arteries were analysed with a 3D reconstruction of computed tomography images and with corrosion casting. There were no clear boundaries between the areas supplied by the four renal arteries because their branches overlapped in most kidney segments.

“…, Ozkan U et al(4) and Dogra A et al(7) reported single renal arteries were more common on the left kidney. Our study is compatible with the study of Ozkan U et al andDogra et al The majority of the analyzed cases were African American and Indian in the study of Satyapal et al Unlike the Satyapal et al, all cases were the caucasian race in our study.…”

Vascular variations of the kidney, retrospective analysis of computed tomography images of ninety-one laparoscopic donor nephrectomies, and comparison of computed tomography images with perioperative findings

Background: In this retrospective study, we aimed to determine the variations of kidney arteries and veins in kidney donor patients who underwent preoperative, computed tomography angiography. Materials and methods:We analyzed kidney computed tomography angiography findings of ninety-one donor nephrectomy patients operated from July 2016 through December 2017.Demographics, vascular diameters, abnormalities, numbers, branching variations, routing variations of arteries, and veins were assessed according to computed tomography angiography images. We also compared the radiological findings with perioperative findings.Two radiologists evaluated computed tomography angiography images, and the same surgical team performed all donor nephrectomies by laparoscopic approach.Results: Ninety-one of the 96 patients involved to study. Forty-six (50.5%) patients were female. Thirty-five (38.4%) of 91 cases had accessory arteries. Seven right (7.6%), one left (1.1%) and eight (8.7%) bilateral double hilar artery was observed on computed tomography angiography. No statistically significant difference was observed in the evaluation of the side of accessory/ polar arteries (p>0.05), and in the evaluation of the distribution of arterial/ venous variations according to perioperative findings (p>0.05). However, in the evaluation of computed tomography angiography images, we found that the diameter of the kidney artery and vein differed according to gender and side. Conclusions:The knowledge of the vascular variations of the kidney is essential for surgeons performing kidney transplantation. It is also essential for urologist and vascular surgeons.Incompatible with the literature, the right kidney has more vascular variations and, one kidney artery is found in the majority of Turkish kidney donor patients.

Background: Para-aortic lymphadenectomy is an essential part of gynecologic oncologic surgical treatment. The surgeon should be aware of the complex usual anatomy and its common variants. Methods: Between January 2021 and May 2023, 58 women underwent para-aortic lymphadenectomy for gynecologic malignancies. Results: Vascular and urinary tract anatomic variants were retrospectively reviewed from the prospective institutional database and results were compared with preoperative contrast-enhanced abdominal CT. Of these 58 women, 47 women had no vascular or urinary tract variants. One woman had a double inferior vena cava, two patients were found to have a retro-aortic left renal vein, four had accessory renal arteries, two had a double left ureter, one had a ptotic kidney in the iliac fossa, and one patient had bilateral kidney malrotation. Anatomic variants in the preoperative CT were described by a radiologist in only two patients, and additional vascular and urinary tract variants were found incidentally at the time of surgery. Conclusions: Acknowledgment of vascular and urinary tract variants is helpful for the surgeon to establish an appropriate surgical plan and to avoid iatrogenic surgical trauma.
