Study on Variations of Anterior Division of Renal Artery.

ABSTRACT

Back ground Urinary System is one of most important system among many systems in our body the most common variations in case of circulatory system usually occur in form of origin, number, length, and diameter. Based on divisions of renal artery, the renal parenchyma is divided into five segments apical, anterior superior, anterior inferior, inferior and posterior. The main renal artery divides initially into an anterior and posterior branch. The anterior branch almost always supplies the upper, middle and lower segments of the kidney. Materials andMethods: Fifty pairs of kidneys with intact abdominal aorta and renal artery were collected from the dead bodies obtained from themortuary of Forensic department, JSSMedical College andMysore Medical College and studied in JSS Medical College. For study of segmental variation corrosion cast technique method was used. Results: In present study type I anterior division of renal artery were found in 31%, type II in 19%, type III in 8%, type IV 20% and type V in 16% of cases. Conclusion: We observed variations in anterior division of renal artery in 100 kidneys and observed 5 types of variation. These variations are helpful for the surgeon performing major surgeries like kidney transplant and partial nephrectomy.
