Ureteral duplication is the most common congenital abnormalities associated with the urinaryurinary tract, and occur in ~1% of the population. Duplications
Gross anatomy
Duplications can occur unilaterally or bilaterally.
It, and may be partial or complete.:
-
Partiallypartially duplicated ureters fuse into a single ureter proximal to the urinary bladder (a.k.a. bifid ureter) -
Inin complete duplication ureters, the duplicated ureter may form a ureterocele, ectopic ureter, or orthotopic ureter.
Epidemiology
It is thought to occur in approximately 1% of the population.
AssociationsRelated pathology
Complete duplications have an associate with increased risk for urinary tract infection, obstruction, and vesicoureteral reflux.
