Resum:	We aim to evaluate the association between sheath size and outcomes in suction mini-percutaneous nephrolithotomy (SM-PCNL). A prospective, multicentre study enrolled 1534 patients undergoing SM-PCNL from March to November 2024 across 30 centres. Patients were stratified into three groups: Group 1 (14-15 Fr, n = 780), Group 2 (16-18 Fr, n = 388), and Group 3 (20-22 Fr, n = 366). Primary outcome was 30-day stone-free rate (SFR) determined by non-contrast CT. Secondary outcomes included complications, operative times and hospital stay. Group 3 achieved the highest zero residual fragment rate (92. 6%) compared to Groups 2 (80. 7%) and 1 (79. 5%) (p.
