The embryogenesis of the kidney and drainage system accounts for the development and frequency of congenital abnormalities. We collected 50 pairs of adult human kidneys to study the renal angioarchitecture from department of anatomy Madras Medical College, Chennai. Out of 50 pairs in one specimen of right kidney we observed duplication of ureter but the left kidney of same pair is normal. The unilateral duplication of ureter extend s from renal pelvis to pelvic brim near the pelvic brim both the duplicated ureter joined later continue as single ureter and entering the urinary bladder. The incidence of partial duplication of ureter is 1% out of 100 kidneys. We also observed inferior segmental artery arising from the aorta as inferior aberrant artery which crosses the duplicated ureter posteriorly instead of going anteriorly. Our study gives primary knowledge to the clinicians about the vascular variations associated with duplication ureter before planning a surgery. [Cukurova Med J 2014; 39(4.000): 855-859]
