Studies on renal arteries origin from the aorta in respect to superior mesenteric artery in Polish population.

Abstract

The aim of the study was to determine the location of the branchingof the renal arteries from the aorta in respect to superior mesenteric artery. Three hundred twenty four vasculorenal samples were collected from corpses (180 male and 144 female), and subject to X-ray contrasting and preparation. The distance between the branching of selected arteries from the superior mesenteric artery (SMA) was measured. Results were subject to statistical analysis. Results were presented in group A (191/324; 58.9%) considering subjects with bilateral, single renal arteries, as well as group B (133/324; 41.1%) considering patients with multiple renal arteries. The average distance between SMA and the renal artery in group A male patients was 0.6 ± 0.57 cm, while in group B 1.3 ± 2.03 cm (p = 0.0001). In the case of female A patients, results amounted to 0.66 ± 0.58 cm and 1.12 ± 1.7 cm, respectively (p = 0.006). The above mentioned left-sided distance in male group A was 0.89 ± 56 cm, while the right-sided distance 0.73 ± 0.94 cm (p = 0.382). In female A patients 0.80 ± 0.50 cm and 0.71 ± 0.89 cm, respectively (p = 0.615). In left-sided group B male patients the distance amounted to 0.87 ± 0.70 cm, and the right-sided distance 0.71 ± 0.60 cm (p = 0.291). Considering female patients results were as follows: 0.82 ± 0.51 cm (left) and 71 ± 1.21 cm (right), respectively (p = 0.706). Knowledge of the described topography of renal artery branching from the aorta should be considered in the preoperative planning of vascular kidney system radiology examinations, as well as retroperitoneal surgical and urological procedures, especially endoscopic kidney transplantations.
