Presegmental Arterial Pattern of Human Kidneys in Local Population

Objective: To investigate the variations in the presegmental arterial pattern of human kidneys obtained from cadavers of the local adult population. Materials and Methods: This study was conducted at Anatomy Department of University of Health Sciences, Lahore, for a period of one year (October 2006-October 2007). Forty four adult human kidneys were obtained after autopsy; they were randomly divided in two groups A and B of right and left kidneys respectively. Simple blunt dissection and corrosion cast techniques were used to study the presegmental arteries. Statistical analysis was carried out by using SPSS version 16.0 and STATA version 8.0. Results: Presegmental arteries were present in 100% of specimens of groups A and B. Variations were seen in the site of origin (extrahilar, hilar and intrarenal) of presegmental arteries of both groups. Conclusion: The presegmental branches of renal artery in local population showed variations different from those reported in the earlier work carried out in other countries
