Variation in Renal Blood Supply and Its Clinical Significance- A Case Report

Variations in the arterial blood supply of kidney are becoming much important due to increasing number of surgical interventions related to kidney and adnexa. Generally each kidney is supplied by a single renal artery, arising from lateral sides of abdominal aorta and entering it through hilum. Presence of extra renal arteries is accountable in cases of renal pathologies, radiological diagnostic procedures, renal transplant, urological and other surgical approaches. A case of anatomical variation of renal blood supply in bilateral kidneys was noted during routine dissection of a 63 year old male cadaver at Department of Rachana Sharir, Sri Dharmasthala Manjunatheshwara College of Ayurveda and Hospital, Hassan, Karnataka, India.
