Which urine pH condition helps dissolve struvite crystals?

Explanation:
Acidic urine promotes dissolution of struvite crystals. Struvite is magnesium ammonium phosphate and tends to form in alkaline urine, especially when urease-producing bacteria raise the pH. Lowering the urine pH reduces struvite stability, causing it to dissolve. Isosthenuric urine (normal urine pH) and dilute urine (low concentration) don’t specifically promote dissolution, whereas acidity directly affects the solubility of struvite. In practice, acidifying urine is a common approach to dissolve existing struvite crystals and prevent recurrence, alongside treating any underlying infection.
