Congenital giant megaureter: first neonatal case.
The authors report the first neonatal presentation of a congenital giant megaureter (CGM), a very rare unilateral urinary anomaly, which is defined as "a ureter whose lumen is congenitally, focally and segmentally dilated to more than 10 times the normal diameter, in presence of normal bladder volume and function." The definition of CGM is purely descriptive; it can be secondary to several different diseases, and in the series of 21 CGM (12 in duplex system) reported by Chen-Ju Huang, the morphology of the distal ureter varied from a near normal caliber to a ureteral stenosis, a ureterocele or a complete ureteral atresia.
