Congenital malformation in the urinary tract

Ureteral Duplication, Ureterocele, and Ectopic Ureter

Development of the urinary organs before birth prepares the body to void urine. Sometimes those organs do not develop correctly, perhaps because of heredity or related to an unknown influence. The result is different anatomy that exists at birth—called congenital malformation.

Congenital malformations of the urinary tract include:

  • Ureteral duplication
  • Ureterocele
  • Ectopic ureter

These conditions will be defined and discussed here.
