[Presence of newberyite in the right kidney and carbonated apatite in the left kidney in a patient with recurrent urinary infections].
In about 20% of the cases, urolithiasis is directly linked to chronic urinary tract infection by urea splitting bacteria, essentially Proteus mirabilis. The stones are generally composed of struvite and carbonate apatite which usually occur as staghorn calculi feared because of their obstructive and infectious consequences that cause important renal damage. The case of a 48 year-old woman with chronic urinary infection is described whose right kidney showed a staghorn calculus essentially composed of newberyite, a very rare constituent of urolithiasis, and whose left kidney contained three carbonate apatite calculi. Clinical and technical examinations, relations between the two mineral constituents are discussed in this paper with a review of the literature on the subject.
