First seen Nov 21, 2025 · Last updated May 12, 2026 · Updated 23 times

Summary

This study looked at 147 patients with kidney stones who had a positive urine culture before a minimally invasive surgery called mini-PCNL. All patients received antibiotics for 5-7 days, and researchers checked if a follow-up urine culture was needed to predict infections after surgery. The goal was to see if waiting for a negative culture is necessary, which could simplify pre-surgery preparation.
