Failure in the process of differentiation of the mesonephric duct is thought to be the cause of upper urinary tract abnormalities. The common nephric duct, the caudal portion of the mesonephric duct between the ureteral bud and its opening into the urogenital sinus, seems to play a central role in the development of this region. However, detailed m...

This anlage is seen as a well-developed bud in the 12.5 day embryo (Fig. 2). The ureteral bud regularly originates from the "knee" of the mesonephric duct, where it bends in a mediocaudal direction to enter the cloaca (Fig. 3). In the 14 day embryo the ureter and renal pelvis can be discerned as isolated structures; in this stage, ...

Removal of toxic substances from the blood depends on patent connections between the kidneys, ureters and bladder that are established when the ureter is transposed from its original insertion site in the Wolffian duct, to the bladder, its final insertion site. The Ureteral Bud Theory of Mackie and Stephens suggests that repositioning of the ureter...
