Bilateral bifid ureter with unilateral renal vasculature variations

摘要

During routine dissection of 82-year-old female cadaver with no known unfavorable medical history, we observed bilateral bifid ureter and variation in arterial supply of left kidney only. Careful examination revealed that there were bifid ureters on both sides enclosed in single facial sheath. It was also observed that both the ureter have different pattern of origin. On the right side, both the ureters were seen to be emerging from the hilum, one below another and joined together at the brim of the lesser pelvis just before crossing the right external iliac artery. Right kidney was supplied by single renal artery lying anterior to both the ureters. On the left side one ureter emerged from the hilum while the second one exited the kidney from a prominent lobule present below the inferior pole.
