Sterilization of single-use flexible ureteroscopes: myths and reality

Introduction. Retrograde flexible ureteroscopy is the most safe and effective method of treatment of patients with kidney stones and urothelial tumors. Since 2017, disposable flexible ureteroscopes (URS) have been introduced into clinical practice. Single use scopes are equal in visualization and usability to reusable ones, and there is no need for complex maintenance. However, the cost of disposable endoscopes remains relatively high for clinics in developing countries, prompting many specialists to sterilize the disposable device and then reuse it again.
