Background: Renal hilum is the middle concavity of the medial border of kidney which communicates with renal sinus. The disposition of renal hilar structures has been described in anatomical textbook from anterior to posterior as the renal vein, renal artery and renal pelvis. Variations in arrangement of renal hilar structures were detected incidentally while performing investigative imaging and angiographic procedures. Anatomical knowledge of structures at the renal hilum is of great importance for various urological surgical procedures and also during interpretation of various radiological techniques related to the kidney.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
