About this study

This is a multicenter, randomized controlled trial comparing retrograde intrarenal surgery (RIRS) using a tip-flexible suction access sheath with standard percutaneous nephrolithotomy (PCNL) for the treatment of 2-3 cm unilateral renal stones. The aim is to evaluate the clinical efficacy and safety of the novel suction sheath-assisted RIRS compared to standard PCNL in terms of stone-free rate and postoperative complications. A total of 308 patients will be enrolled across four centers in China.
