Renal vascularization anomalies in the Polish population

The aim of the study was to determine the incidence of renal venous system congenital anomalies in the Polish population.

Vascular kidney samples were investigated by means of preparations and X-ray contrasting. The study the group comprised 281 male and 269 female specimens.

Congenital anomalies were diagnosed in 186 patients (33 8% of all cases), and they were more frequent in men than in women, albeit that difference was non-significant. The following anomalies were most commonly observed: multiple venous variations on the right side (20.4%), retroaortic course of the left renal vein (4.2%), and circumaortic venous ring of the left renal vein (3.8%). Other anomalies were diagnosed in 1%-2% of cases.

Awareness and preoperative assessment of the venous system before abdominal aortic surgery, isolated collection of renal venous blood samples, and urological or kidney transplantation procedures is essential.
