Which organism is commonly associated with struvite stone formation?

Explanation:
Struvite stones form when urine becomes alkaline due to urease-producing bacteria that split urea into ammonia. The resulting higher pH enables magnesium ammonium phosphate crystals to precipitate and grow into stones, sometimes forming large staghorn calculi. Proteus mirabilis is the classic urease-producing uropathogen that drives this process, making it the most common organism associated with struvite stones. While other urease-positive bacteria can contribute, Proteus’ potent urease activity is the hallmark link to these stones.
