Metaphylaxis of Infected Kidney Stones After Percutaneous Nephrolithotripsy

Kidney stone recurrence, particularly infection-related stones, remains a significant clinical problem after percutaneous nephrolithotripsy (PCNL). Bacterial colonization and persistent infection are recognized contributors to stone recurrence.

This study evaluates the effectiveness of intrarenal dioxidine instillation as a metaphylactic measure to reduce recurrence of infection-related kidney stones following PCNL. Patients undergoing PCNL will receive standard treatment, with or without adjunctive intrarenal dioxidine administration. The study aims to assess whether this approach reduces stone recurrence and infection-related complications.
