Variations in the renal vessels have been observed frequently in routine dissection and surgical practice, but existing with congenital anomalies of kidneys or ureters or suprarenal glands is very rare. Accordingly the aim of this study was designed to evaluate the prevalence of anomalous renal vasculature existing with congenital anomalies of kidn...

... gland. Surprisingly the middle suprarenal branch originated from the abdominal aorta after supplying suprarenal gland, within the gland it gave off a testicular artery which descends in front of the hilum of the right kidney.

... Variations in the ramification patterns of renal and testicular vessels have been reported in detail, particularly with respect to their possible number, origin, course, and termination [8,20,23,25,27]. However, such mutations sometimes occur simultaneously and in various combinations, and may be accompanied by malformation in the kidney and urinary tract [1,2,9,11,13,18,21,26,28]. Compared to a single variation, the presence of multiple variations increases the risk of unexpected injury to the urogenital vessels during surgical procedures; therefore, a detailed description of combined variations is helpful to ensure safe surgery. ...
Variations in the pattern of urogenital vessels can arise as a single occurrence or as a combination, which may increase the risk of unexpected injury during surgical procedures. Multiple variations in the renal and testicular vessels, in a novel combination, were observed during dissection of an 87-year-old Japanese male cadaver. In the present case, the patient had two renal arteries on each side. On the right side, the superior and inferior renal arteries emerged from the abdominal aorta at the L1 and L4 vertebrae levels, respectively. On the left side, the superior renal artery originated from the abdominal aorta at the level of the L1/L2 intervertebral disc, whereas the inferior renal artery arose at L4. The right testicular artery emerged from the abdominal aorta at the level of the L2 vertebra and crossed the inferior vena cava posteriorly. The venous system also exhibited some variations. The left renal vein passed posteriorly to the abdominal aorta and opened into the inferior vena cava at the level of the L2 vertebra. On the course to the inferior vena cava, the left renal vein was connected only to the first lumbar, azygos, and hemiazygos veins; blood was not collected from the left testicular and suprarenal veins, which usually open to the left renal vein. The patient had two right testicular veins. The lateral one opened into the angle between the right renal vein and the inferior vena cava at the level of the L2 vertebra, and the medial one drained into the inferior vena cava at a level slightly lower than the lateral one. Knowledge of the possible anatomical variations may be beneficial for performing safe retroperitoneal surgery and understanding the development of these vessels.
