What type of kidney stone is associated with Proteus Mirabilis infection?

• A. Cystine
• B. Calcium Oxalate
• C. Struvite
• D. Uric Acid

Answer: (C)

Struvite stones are primarily associated with urinary tract infections (UTIs) caused by urease-producing bacteria, such as Proteus Mirabilis. When these bacteria infect the urinary system, they hydrolyze urea into ammonia, leading to an increase in urine pH. This alkaline environment facilitates the precipitation of magnesium, ammonium, and phosphate salts, which combine to form struvite stones. These stones are often referred to as "infection stones" because their formation is closely linked to the presence of UTIs. In contrast, other types of stones, such as cystine, calcium oxalate, or uric acid stones, are formed due to different metabolic conditions or dietary factors and are not directly related to the presence of specific bacterial infections. Hence, the correct association of struvite stones with Proteus Mirabilis highlights the influence of infection on the composition and formation of kidney stones.
