BACKGROUND
Normally each kidney is supplied by one renal artery, which is originating from the abdominal aorta. The present study is aimed at the supernumerary renal arteries and their importance.
MATERIALS & METHODS
20 cadavers which are used for undergraduate dissection constitute the material for study. During routine abdominal dissection of cadavers, kidneys and renal arteries are exposed, morphological variations are noted.
RESULTS
We observed supernumerary renal arteries in 12 out of 20 cadavers. In these, 7 cadavers showed abnormalities on Right side, 5 cadavers showed abnormalities on Left side. In 6 cadavers out of 7, supernumerary arteries were arising from abdominal aorta. In 1 cadaver out of 7, supernumerary arteries were arising from renal artery. In 4 cadavers out of 5, supernumerary arteries were arising from abdominal aorta. In 1 cadaver out of 5, supernumerary arteries were arising from renal artery. These supernumerary renal arteries enter into the kidney through hilum or superior pole or inferior pole.
CONCLUSION
Renal artery variations are very important for surgical procedures over the kidneys like renal transplantation, urological procedures, renal angiographic studies.
