ABSTRACT
Ureteroceles are congenital, cystic dilations of the terminal,
intravesical portion of the ureter. The associated ureteral
orifice, often extremely difficult to visualize, may be partially
or totally obstructed, resulting in variability in size from
small to very large. They can also vary in location from
intravesical to ectopic. The use of fetal ultrasonography has
improved the diagnosis of ureteroceles, however, they often
remain difficult to diagnose and require complete postnatal
evaluation when suspected.
