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