Abstract
With advancements in laser technology and urological techniques, flexible ureterorenoscopy has emerged as a vital surgical approach for managing stone disease. Various techniques can be employed to customize endourological stone treatments. Despite the continuous evolution of equipment, it remains crucial to comprehend the fundamental steps of the procedure. This paper offers a comprehensive step-by-step guide that integrates the latest advancements in both scopes and lasers. Additionally, it outlines potential pitfalls and strategies to circumvent them, aiming to achieve optimal stone clearance and deliver individualized patient care safely and efficiently.
