AIM To study the variations in the arrangement of renal hilar structures in human cadavers which are observed in anteroposterior direction. MATERIALS & METHODS Forty two (42) embalmed cadaveric kidneys are observed for studying the variations, the renal hilar structures arrangement and for branching of renal vessels. The number of branches of renal artery, number of supernumerary renal arteries & arrangement of structures at the hilar and prehilar region is studied. RESULTS In the present study, 29 kidneys were having normal renal arteries, whereas 13 kidneys were having the supernumerary renal arteries. In these 29 kidneys group, 15 kidneys (51.7%) were having common pattern of renal hilar structures, arrangement is RV-RA-RP in an anteroposterior direction. In 7 kidneys (24.1%), AD & PD of RA are present in between the RV & RP. In 4 kidneys (13.4%), RV is present in between AD, PD of renal artery. CONCLUSION Information about the arrangement of renal hilar structures is very important for general surgeons, urologists & transplant surgeons because this knowledge minimises the intraoperative & postoperative complications.

While doing a routine dissection in an 85 years old cadaver, it was observed that the coeliac trunk arised as gastro splenic trunk and the common hepatic artery arised from the superior mesenteric artery instea d of the coeliac trunk. Knowledge of anatomical variants of coeliac trunk, hepatic vascular structures is of great importance in general surgery, especially hepatic surgery. As coeliac trunk supplies the foregut, the anomaly and morphometric variation may lead to abnormalities of the foregut and its derivatives. This leads to anatomical, surgical and clinical complications. This knowledge is also of great importance with regard to liver transplantations, laparoscopic surgeries, radiological procedures, and the treatment of penetrating injuries involving the peri - hepatic area
