Bone lithiasis or bone metaplasia?
A case in which bone has been found in the upper urinary tract is reported. Since the physiopathology and morphological characteristics of this tissue do not meet the requirements needed to be defined as a urolith, we believe this is a case of bone metaplasia and not urinary lithiasis.
