ABSTRACT: Objective: To evaluate the comprehensive efficacy of combining a flexible negative pressure suction sheath with a ureteroscopic soft scope in treating renal calculi. Methods: A total of 200 patients undergoing renal stone treatment at our hospital were enrolled in the study, with hospitalization periods spanning from January 2023 to April 2025. Patients were randomly assigned to either the control group (standard ureteroscopic soft scope) or the observation group (flexible negative pressure suction sheath combined with ureteroscopic soft scope). Comparative analysis was conducted on surgical parameters, renal injury, inflammatory response, and complications between the two groups. Results: The observation group demonstrated significantly shorter operation time, higher stone clearance rate, and earlier postoperative discharge compared to the control group. Additionally, the observation group exhibited a lower inflammatory response and reduced renal function impairment. Postoperative complication prevention was also more effective in the observation group (P
