Ureteral Duplications and Ureteroceles

Abnormal development of the ureteric bud causes both ureteral duplication and ureterocele. Proximal branching of the ureteric bud is the cause of incompletely duplicated or bifid ureters, but completely duplicated ureters are caused by the development of two separate ureteric buds from the mesonephric duct. Ureteroceles are probably the result of abnormal distal ureteral canalization of Chwalla’s membrane.
