DIVERSITY IN ARTERIAL SUPPLY OF KIDNEY AND IT’S CLINICAL IMPLICATIONS–A CADAVERIC STUDY

Abstract

Kidneys are excretory organs situated in the lumbar region in adult human. A pair of kidney label as right and left kidney, situated on eighter sides of abdominal aorta. Kidneys are supplied by a renal arteries which are the branches of abdominal aorta arises laterally at the level of L1 vertebral body, below the origin of superior mesenteric artery.
Variations in renal vasculature remain undiscovered until they noticed during cadaveric dissection, surgical procedures or radiological examinations of the patients. Hereby we are presenting variations found in routine cadaveric dissection of undergraduate students as variations in arterial supply of kidney.
In present study there were 50 specimens studied in 25 cadavers. In which 44 specimens with male and 6 are of female gender. There is more than one variation is seen in single specimen.14 % of them show multiple renal arteries. 12 % shows superior polar artery, 2% shows presence of inferior polar artery, and 22% are with prehilar baranches.24% shows more than one branch entering into the hilum. In present study all described renal arteries are the branches from abdominal aorta. There is no any bilateral sementery was found in any cadaver showing variation.
Awareness must be created about the vast variety of variations in arterial supply of kidney. The knowledge is required for the Surgeons, Radiologists and Urologist, kidney transplantation procedures to avoid fatal complications during various surgeries and to the physicians while dealing with patients like hypertension and hydronephrosis.
