Single use flexible ureteroscopes: a review of current technologies and cost effectiveness analysis.

Abstract

Flexible ureteroscopy (fURS) has evolved into both diagnostic and therapeutic modalities. Our review discusses the cost-effectiveness of single use flexible ureteroscopes (su-fURS) and the use of these instruments in routine urological practice. There are studies which support the use of su-fURS with an argument of both cost and clinical utility over reusable flexible ureteroscopes (ru-fURS). However, the cost may vary across countries, hence is difficult to compare the results based on the current literature. Perhaps therefore there is a role for hybrid strategy incorporating ru- and su-fURS, where su-fURS are employed in complex endourological cases with a high risk of scope damage or fracture to preserve ru-fURS, with the ability to maintain clinical activity in such an event. While there seems to be some cost advantages with su-fURS with reduced sterilization and maintenance costs, the data supporting it is sparse and limited. This choice of scope would depend on the durability of ru-fURS, procedural volumes, limited availability of sterilization units in some centers and potential risk of infectious complications. It is time that cost-benefit analysis is conducted with defined outcomes for a given healthcare set-up to help with the decision making on the type of scope that best serves their needs.
