"Morphological Study Of The Renal Artery In 20 Human Cadavers: A Cross-Sectional Study."

Abstract

Introduction: The renal artery, a direct lateral branch of the abdominal aorta that arises below the origin of the superior mesentery artery (SMA) between the lumbar vertebrae L1 and L2, supplies the kidney. Both the urinary and reproductive systems develop from intermediate mesoderm. Permanent renal arteries develop from lateral splanchnic branches that supply the pronephric, mesonephric, and metanephric kidneys and the gonads.

Materials and methods: The present study was carried out on 40 renal arteries (24 males and 16 females) in the Department of Anatomy, Krishna Mohan Medical College & Hospital, Mathura, Uttar Pradesh, India, by dissection method. The specimens for the study of renal arteries in 20 human cadavers taken from cadavers preserved in 10% formaldehyde solution. 

Results: The mean length of the renal artery was (36.4 ± 11.77) mm and (27.4 ± 11.74) mm on the right and left sides, respectively. The average distance from the superior mesentery artery to the renal artery's origin was (16.1 ± 7.09) mm on the right and (14.9 ± 5.94) mm on the left. The mean diameter of the renal artery at its origin was (5.3 ± 1.25) mm and (5.5 ± 1.92) mm on the right and left sides, respectively.

Conclusion: These cadaveric dissections of renal arteries and their variations may help surgeons, radiologists, and clinicians in surgical procedures, renal transplantation, and treatment of patients.
