ABSTRACT
Abstracts: Background: Knowledge of arrangement of renal hilar structure is essential in the era of minimally invasive surgery. Nephron sparing surgeries like partial nephrectomy by laparoscope is treatment of choice and in this surgery hilar dissection is one of the important steps. However, in literature very few reports are available regarding the different patterns of dispositions of renal hilar structures. Aim of present study was to evaluate the arrangement of renal hilar structures. Methodology: Present work was carried out on fifty seven pairs of morphological normal kidneys of embalmed cadavers. Renal hilum of each kidney was dissected carefully to see the arrangement of renal artery, vein and pelvis. Results: Arrangement of renal hilar structures showed great variation. We classified arrangement of renal hilar structures into ten different patterns. In 22.80 % kidney we observed the arrangement of hilar structures according to textbooks. We observed anterior and posterior tributaries of renal vein in 32.45% and in 41.22% kidneys pelvis was the posterior most relation. Conclusion: Present study will help to understand the better knowledge of the disposition of hilar structures for the urological surgeons, radiologist and anatomists.
