Struvite stones form in which urine condition?

Explanation:
Struvite stones form in alkaline urine due to infection with urease-producing bacteria. Urease breaks down urea into ammonia, which raises the urine pH. In this alkaline environment, magnesium, ammonium, and phosphate combine to precipitate as magnesium ammonium phosphate, giving rise to struvite stones (often called infection stones). This contrast with stones like uric acid, which form in acidic urine, while others like calcium oxalate can form across a broader pH range.
