Surgical technique to achieve high durability of flexible ureteroscopes: A single hospital experience.

Background: To describe a novel operative technique resulting in extended durability and improved ease of use of current flexible ureteroscopes (FURS). A surgical method employing a modified technique of using an Olympus digital flexible URF-V ureteroscope was developed.

Methods: We retrospectively studied 546 patients who underwent retrograde intrarenal surgery (RIRS) using this modified approach performed by a single surgeon at our hospital, and investigated the outcome and durability of the ureteroscope.
