“…The most frequent perihilar branching pattern, according to the study by Weld et al [14] , consisted solely of segmental arteries without any pre-segmental arteries. (Fig - 7) One case of higher (thoracic) origin of the renal artery is also found in the study (at D10 vertebral level) [15] . In the current study, 77% of kidneys have a single renal artery, and 23% of kidneys have renal artery variants.…”

The most frequent anatomical variations of the renal arterial system are accessory renal arteries (supernumerary renal arteries) and aberrant renal arteries, which occur in varying numbers among various ethnic and racial groups. Prior to surgery, understanding these variations is crucial because it affects the decision to use donor kidneys, the planning of partial nephrectomy, and other urological procedures. Along with the main renal artery on the same side, there is also an accessory renal artery. The aberrant artery supplies the kidney without passing through the hilum, whereas the main renal artery enters the kidney through the hilum to do so. Aim: This tertiary care hospital-based study aims to know the prevalence of variations of the renal arterial system including accessory renal artery, their distribution pattern, and association with gender, age, and side predilection in population of Kancheepuram and West Chennai district of Tamil Nadu. Methodology: One hundred adults (62 males, 38 females; mean age: 45 +/-25 years) inclusive of prospective live renal donors undergoing pre-operative CT renal angiogram for operative planning and other patients undergoing CECT Abdomen for various abdomino-pelvic pathologies were selected for the study. Research Design: it is a cross-sectional descriptive study conducted in the Department of Radiology, of a tertiary care hospital in Kancheepuram district of Tamil Nadu, India. Results: Renal artery variants (including Accessory renal and aberrant renal arteries) are present in 23% of kidneys. The prevalence of renal artery variants in malesis 30%, and in females -11%. On the right side the prevalence is 60% and on the left side is 26%. The prevalence of bilateral renal artery variants is 11%.

“…Unusual origins of variants were observed from several arteries such as - external iliac, median sacral, splenic, lumbar, superior suprarenal, inferior phrenic, thoracic aorta, etc. [ 24 ]. But in the present study, we noted the origin of renal arteries to be only from the abdominal aorta.…”

Background: A single renal artery supplies the kidney in 70% of the population but variation exists in the remaining 30%. Multiple renal arteries (MRA) in different permutations and combinations are one of the many forms of variants. Lack of awareness of multiplicity could have detrimental effects on the outcome of renal surgery. The present study aims at identifying the variants of renal artery based on its origin, multiplicity, and portal of entry in a cohort of people belonging to Southern India and its clinical implications thereof.Methods: Multi-detector CT (MDCT) images of renal vasculature of 100 kidneys from 50 live kidney donors who attended the Department of Nephrology of our institution, from 2016 to 2018 were collected and studied for variations in renal arterial anatomy.Results: Out of the 18% of kidneys observed with multiple renal arteries, 88.8% had double renal arteries (DRA) and 11.1% had triple renal arteries (TRA). Common types of the double renal arteries were -two hilar arteries (31.3%) and one hilar with one inferior polar artery (IPA, 31.3%). Triple renal arteries types -50% with one hilar, one superior polar, and one inferior polar; 50% with two hilar and one inferior polar artery. No statistically significant association was noted between the incidence of multiple renal arteries and its laterality (p-value=0.193). Conclusion:A thorough understanding of the renal artery variants is crucial for safe and efficacious uroradiological interventional procedures.
