Abstract:

Context: Most common type of congenital abnormality of urinary system is the abnormality of renal collecting system. One such variation is presence of bifid ureter.

Objective: To describe and analyze the clinical and embryological significance of bilateral bifid ureter with accessory renal artery.

Design: The presence of bilateral bifid ureters was seen as an incidental finding during routine educational dissection. The etiology of this variant is fission of the ureteric bud during embryogenesis. In the same cadaver, bilateral accessory renal artery was seen, arising from abdominal aorta opposite to inferior poles of kidneys.

Outcome: The knowledge of relationship of renal arteries and collecting system is necessary for effective endo-urological applications and intra-renal surgeries.

Conclusion: Bifid ureter with accessory renal artery forms one of the common differential diagnoses for ureteric calculi. Such anatomical variants may simulate pathological obstruction of urinary tract and must be considered while performing endo-urological procedures.

Keywords: Bifid ureter, accessory renal artery, bifid pelvis.
