title: Nephrogenic metaplasia of the ureter.
abstract: A case of nephrogenic metaplasia of the left ureter occurring in a 7-year-old male child, associated with recurrent urinary infection and previous surgical intervention, is described. This is to our knowledge the third reported case of this entity. Nephrogenic metaplasia involves the transitional epithelium of the urinary tract and results in the formation of structures histologically similar to renal tubules.
