Abstract
INTRODUCTION: Variations in the configuration of the renal arterial supply are common and so a description of the “normal pattern” is somewhat arbitrary. These variations are of considerable practical importance. The advent of more conservative methods of renal surgery has necessitated the precise knowledge of renal vascularisation, which has consequently assumed a new vista in the transplant surgery. The kidneys are pair of essential excretory organs which elaborate urine and eliminate nitrogenous waste products of protein metabolism from the blood and maintain electrolyte and water balance of the body. They also have endocrine functions like production of renin, erythropoietin and 1, 25-hydroxycholecalciferol. AIM OF THE STUDY: Aim and objectives of the study are to Study the number, Level of origin, Source of origin, Dimentions and site of division of renal arteries and accessory renal arteries and to document any variations and compare it with previous studies. MATERIALS AND METHODS: The present study was carried out in 50 specimens obtained from formalin preserved human cadavers of Institute of Anatomy, Madurai Medical College. OBSERVATION AND RESULTS: The present study observed the following findings. 76% of single renal artery, 20% of double renal artery and 4% of triple renal artery. In 24% of the specimens the origin of the renal artery was in same level, 60% of right renal artery had a higher origin and 16% left renal artery had a higher origin. 22% of accessory renal arteries arose from Aorta and 6% originated from main renal artery. The mean length and SD of the right renal arteries were 4.10cm and 0.923cm and the left renal arteries were 3.56cm and 0.648cm respectively. The mean length and SD of the right accessory renal arteries were 3.53cm and 1.403cm and the left accessory renal arteries were 3.93cm and 0.755cm respectively. The mean width and SD of the right renal arteries were 0.444cm and 0.132 and the left renal arteries were 0.472cm and 0.14 respectively. The mean width and SD of the right accessory renal arteries were 0.33cm and 0.10cm and the left accessory renal arteries were 0.26cm and 0.07 respectively. Extrarenal division of renal arteries was observed in 98% and the intra renal division was in 2% of specimens which was seen only on right side. CONCLUSION: Kidneys with multiple renal ateries are not ideal for renal transplant as rejection will be more in multiple renal arteries. So it is required that the eligible donors are to be carefully investigated prior to donation of kidney. The arterial pattern of kidneys show differences among different populations. Accordingly, with increasing use of invasive diagnostic and interventional procedures, data on type and frequencies of vascular variations from various population is essential. Hence this study was done to focus on anatomy and variation of renal arteries in Tamilnadu population.
