Prospective comparative study between the effect of CIDEX OPA and STERRAD NX on the durability of digital flexible ureteroscope.

Purpose: We compared the effect of chemical disinfection (CIDEX OPA) and low-temperature hydrogen peroxide gas plasma (STERRAD NX) on two brand new digital flexible ureteroscope (DFU) (Flex-Xc) using subjective and objective parameters.

Methods: Over 11-month period, all flexible ureteroscopic procedures that fulfill the inclusion criteria were done by two brand new flexible ureteroscopes and were prospectively evaluated. Intraoperative data included total operative time, laser power and duration, stone criteria and subjective evaluation of the procedure as well as visibility and maneuverability scores were reported.
