Brief Case: Proteus mirabilis Coraliform Lithiasis and Bacteremia in Catheterized Patient

This clinical vignette describes Proteus mirabilis causing coraliform renal lithiasis and secondary bacteremia in an elderly catheterized patient. The case illustrates the importance of recognizing urease-producing organisms in urinary tract infections and their potential for stone formation and bloodstream invasion. It serves as an educational reminder for clinical microbiologists about the pathogenic mechanisms linking catheter-associated UTI to systemic infection.
