Ureteral duplication

Last revised by Dr Naim K on 15 Jan 2021

Ureteral duplication is the most common congenital abnormality associated with the urinary tract, and occurs in ~1% of the population.

Gross anatomy

Duplication can occur unilaterally or bilaterally, and may be partial or complete:

  • partially duplicated ureters fuse into a single ureter proximal to the urinary bladder (also known as bifid ureter)
  • in complete duplication, the duplicated ureters may form a ureterocele, ectopic ureter, or orthotopic ureter

Related pathology

Complete duplications are associated with an increased risk for urinary tract infection, obstruction, and vesicoureteral reflux
