7.7.1 Secondary reflux

Predecessor of a secondary reflux is not an inborn primary disturbance of the terminal ureter, but rather an anatomically or functionally obstructive or inflammatory illness of the bladder, or direct damage to a previously intact orifice. It seems that many refluxes, especially of lower grade l-lll, are secondary refluxes and may disappear with the maturation of the bladder function.
