[Recurring pseudo-urolithiasis]

Abstract

We report about a case with simulated recurrent urolithiasis. The patient introduced foreign bodies (gypsum) into the bladder. Often the stones had to be removed from the bladder and the right refluxing ureter. The diagnosis of the foreign bodies was made after 2 years of malingering by X-ray diffraction (analysis: gypsum = CaSO4 . 2 H2O).
