Comprehensive Study of Arrangement of Renal Hilar Structures and Branching Pattern of Segmental Renal Arteries: An Anatomical Study

Background The knowledge of renal artery (RA) and its segmentation is critical before attempting any surgical procedure kidney. RA receives blood supply from various arteries during descent in the embryonic period. As a result, segmental RAs show lot variability site pattern origin as well point entry Aim/objective aim to study variable existing different arrangement structures at hilum. Methods 205 kidneys (68 paired 69 unpaired) was studied exclusively observed cadavers by dissecting 161 kidneys, making resin/silicon casts 34 radiological imaging 10 kidneys. Results results obtained were quite significant provided detail understanding five main Great variations seen disposition Six patterns hilum obtained. Pattern 1 commonest with an incidence 30.3% followed 2. their into kidney recorded tabulated. classified types based on frequency occurrence decreasing order. In each them, Type variant apical (A), anterior upper (AU), middle (AM), lower (L), posterior (P). Conclusions hilar has been six branches have categorized well. will be invaluable for accurate radiographic interpretation vasculature effective planning cases involving transplantation, trauma, partial nephrectomy. Furthermore, it serve prevent complications procedures.
