Abstract:
During ureteroscopic holmium laser lithotripsy for complex upper ureteral calculi, stone fragments are prone to migrate into the kidney, leading to a decreased primary stone-free rate and increased need for secondary surgeries and healthcare costs.Based on recent clinical studies and literature evidence, this article summarizes and compares strategies for preventing stone escape during ureteroscopic treatment.Comprehensive analysis of existing research indicates that auxiliary measures, such as instrument coordination, physical interception, or negative pressure suction, demonstrate potential clinical value in preventing stone migration, with devices like the NTrap basket showing relatively prominent efficacy.However, most related studies are single-center retrospective analyses, and further validation through multicenter randomized controlled trials is needed to guide individualized treatment selection.This review outlines advances in the prevention and management of stone escape for clinical reference.
