Technological innovation and revolution with single-use digital flexible ureteroscopes: a review from section of EAU Endourology

PURPOSE OF REVIEW: Numerous scope-related innovations have taken place in the field of endourology. The presented analytical review is aimed at studying the technical innovations of the single-use digital flexible ureteroscopes. In November 2024, a comprehensive search was done for information on latest disposable flexible digital ureteroscopes, as well as their various unique characteristics. A thorough examination was conducted for image qualities; sizes and channels; and deflection capabilities. Furthermore, supplementary features about the latest advances were assigned to a separate group including 'Unique' solutions. Using the last search query, various innovations in flexible ureteroscopy in general were also searched and sorted into appropriate groups. RECENT FINDINGS: Modern single-use flexible digital ureteroscopes are characterized by advanced technologies for transmitting light and images, miniaturization, as well as by a number of unique solutions that were previously characteristic only of semi-rigid or fiberoptic endoscopes. These include features such as integrated buttons for data recording, self-locking mechanism, separate ports, rotating shaft, direct-in-scope suction, pressure monitoring, enhanced tip control and customizable settings. SUMMARY: Since their introduction in urology, endoscopes have undergone many changes, as illustrated by the example of single-use flexible digital ureteroscopes. The imaging quality has improved, the dimensions of both the distal tip and shaft have decreased, with over 15 manufactures producing and distributing these scopes. A lot of new additional new features are likely to enhance the efficacy and safety of ureteroscopic procedures.
