[Early diagnosis of congenital ureterocele].

Ureterocele is a congenital urinary abnormality characterized by the presence of an intrabladder hernia or cystic ballooning of the lower end of an ureter lying between the mucosa and muscle of the bladder. The abnormality leads to urinary retention and recurrent urinary tract infection which can cause irreversible damage to the kidney. It can become very large and is the most common cause of bladder outlet obstructions in infant girls. It may be associated with serious urologic abnormalities in either sex. This abnormality can be suspected in the fetus by ante-natal echography and confirmed by other X-ray investigations after birth.
