STUDY OF VARIATIONS IN SUPERIOR SEGMENTAL BRANCH OF RENAL ARTERY

Background: Based on vascular divisions the renal tissue divided into five segments that are apical, anterior superior, anterior inferior, inferior and posterior. The apical segment occupies the antero medial region of the superior pole. The superior segment includes the rest of the superior pole and the central antero-superior region. The segmental arteries of the kidney supply the organ in such a way that, each renal pole receives its own artery while, the anterior portion between the poles is supplied by an upper and lower segmental vessel. The present study concentrated on variation of superior segmental artery which is help in nephrology clinical practice. Materials and Methods: Fifty pairs of kidneys with intact abdominal aorta and renal artery were collected from the dead bodies obtained from the mortuary of Forensic department, JSS Medical College and Mysore 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 superior segmental artery were found in 28%, type II in 12%, type III in 14%, type IV 20%, type V in 1% o and type VI 23% of cases. Conclusions: We observed variations in superior segmental branch of renal artery in 100 kidneys and observed 6 types of variation. These knowledge of vascular segments of kidney helpful for the clinician to do renal transplantation interventional radiological procedures.
