“…In general, the data with respect to the length of the renal arteries are consistent with those from the literature. 24 However, the diameters of the first right and left renal arteries measured in this study, with 4.9±1.2 and 5.2±1.4 mm, respectively, are approximately 1 mm lower than those in the literature, where the not gender-corrected values are between 5.71±0.83 and 6.9±0.2 mm. 24 The influencing factors on the diameters of the renal arteries that were defined are plausible—the lack of effect of the extent of atherosclerosis on the diameters of the renal arteries can likely be attributed to the fact that most renal arteries have scores of 0 and 1, that is, nil to slight atherosclerotic changes.…”

“… 22 Data on lengths and diameters of the renal arteries in vivo, are rare in literature. 23 24 Diameters and lengths are dependent on gender 23 and on the presence of additional vessels. 25 The data do not reflect the curvature of the vessels in the area, the resulting ovality of the inner lumen, the wall lengths that vary between larger and smaller circumferences, or the fluctuation of the diameters along the course of the vessel.…”

ObjectiveThe aim of this study was to describe the renal arteries of humans in vivo, as precisely as possible, and to formulate an expected value for the exclusion of renal denervation due to the anatomical situation based on the criteria of the Symplicity HTN trials.Design and settingIn a retrospective cohort study, the renal arteries of 126 patients (57 women, 69 men, mean age 60±17.2 years (CI 57.7 to 63.6)) were segmented semiautomatically from high-contrast CT angiographies.ResultsAmong the 300 renal arteries, there were three arteries with fibromuscular dysplasia and one with ostial renal artery stenosis. The first left renal artery was shorter than the right (34±11.4 mm (CI 32 to 36) vs 45.9±15 mm (CI 43.2 to 48.6); p<0.0001), but had a slightly larger diameter (5.2±1.4 mm (CI 4.9 to 5.4) vs 4.9±1.2 mm (CI 4.6 to 5.1); p>0.05). The first left renal arteries were 1.1±0.4 mm (CI 0.9 to 1.3), and the first right renal arteries were 0.3±0.6 mm (CI 0.1 to 0.5) thinner in women than in men (p<0.05). Ostial funnels were up to 14 mm long. The cross-sections were elliptical, more pronounced on the right side (p<0.05). In 23 cases (18.3%), the main artery was shorter than 2 cm; in 43 cases (34.1%), the diameter was not >4 mm. Some 46% of the patients, or 58.7% when variants and diseases were taken into consideration, were theoretically not suitable for denervation.ConclusionsBased on these precise measurements, the anatomical situation as a reason for ruling out denervation appears to be significantly more common than previously suspected. Since this can be the cause of the failure of treatment in some cases, further development of catheters or direct percutaneous approaches may improve success rates.

“…Studies have been performed in different parts of worldto establish normal reference range of renal artery dimensions. 3 , 16 , 17 Review of literature showed that studies performed in our population were mainly in context with renal vascular pathologies as renal artery stenosis and renovascular hypertension. 18 - 20 Thus, this study was conducted to determine a reference range of normal renal artery measurements and to find itsvariation with side of artery, gender and age in our population by using MDCT angiography in our population.…”

Objective:To determine a reference range of renal artery measurements by using Multidetector Computed Tomography (MDCT) angiography and to find association of renal artery measurements with side of artery, gender and age.Method:Two hundred and fifty study participants without renal artery disease who werepresented to Radiology Department, Ziauddin Hospital, Karachi, from November, 2016 to April, 2017 were included in this study. Main renal artery measurements were taken on Multidetector computed angiography and variation with side, gender and age were analyzed. Statistical analysis was done on Statistical Package for Social Sciences (SPSS) version 20. Independent sample T test, one way ANOVA and Pearson’s correlation analysis were applied. P-value of < 0.05 was considered significant.Results:A significance difference (p=0.001) was seen between mean right renal artery (diameter 6.66 ± 0.39 mm; length 44.69 ± 2.48 mm) and left renal artery (diameter 6.79 ± 0.36; length 35.10 ± 2.86 mm). Females found to have smaller mean diameter and length of renal arteries than males. However, a weak negative correlation was seen between mean renal artery diameter and age (right r= -0.158, p=0.0121; left r= -0.017, p= 0.708).Conclusion:The mean diameter and mean length were found to be significantly different between right and left main renal artery and between males and females. A significant weak negative correlation was observed between renal artery diameter and age.

“…As previously described, anatomical variations of renal arteries are important in the preoperative assessment of patients undergoing nephrectomy for kidney donation, the technique of choice is laparoscopy and the risk of hemorrhage from vascular injury can be substantially reduced if there is prior knowledge about the preoperative radiological evaluation of renal angiography of the donor using non-invasive and effective multidetector computed tomography in the diagnosis (BORDEI; APTE; ILIESCU, 2004;STOISA et al, 2009). In addition, the angiotomography technique has been used to detect the quantity and route of renal arteries, replacing conventional arteriography in evaluation, vascular anatomy study and diagnosis of renal vascular pathologies (PALMIERI et al, 2011).…”

ABSTRACT:Two renal arteries supply the human kidneys: one to the right kidney and another to the left kidney, both branches of the abdominal aortic. Renal artery duplication is an anatomical variation, which is a normal flexibility of the topography and morphology in body structures. Functionally, it does not impair the body, as the blood supply is vital to tissue survival. In this context, the case study has great importance, once knowing the variations of the renal vessels assist when structuring surgeries and radiological studies in humans. Variations in vascular anatomy are often found in humans. Several authors characterize it: the prevalence of multiple vessels occurs in approximately 20-50% of cases. This is an observational study; we aimed to describe the anatomical variations concerning the duplicity of the renal artery in human cadavers, focusing on possible implications to clinical and surgical procedures. We dissected and analyzed four urinary block systems in adult cadavers, male, with focus on the vascularization. In these, two right kidneys present double renal arteries. Thus, we can infer that this knowledge can be used to improve surgical interventions, such as transplants.
