                • Congenital dilatation of intramucosal segment of ureter
                  • Dilated segment prolapses into bladder lumen
                • Variable types
                  • Simple
                    • Occurs at normal ureterovesical junction
                    • Located at trigone of bladder
                    • Less commonly seen in fetus
                  • Ectopic
                    • Almost always associated with renal duplication
                    • Located medially and inferiorly to trigone, near bladder base
                    • Ectopic ureter is usually stenotic at bladder
                    • Ectopic ureter may insert outside of bladder
                      • Directly onto perineum
                      • Urethra
                      • Females: Vagina, uterus
                      • Males: Epididymis, seminal vesicles, ejaculatory ducts, vas deferens
                  • Cecoureterocele (uncommon)
                    • Dissects submucosally under bladder trigone into urethra
