Single-use flexible ureteroscopes (su-fURS) aim at overcoming the main limitations of conventional reus-able flexible ureteroscopes (re-fURS) in terms of acquisition and maintenance costs, breakages, and repro-cessing. We aimed to perform a literature review on available re-fURS and su-fURS performances with a focus on costs. A search of Medline, EMBASE, CINAHL, and Scopus databases was performed to identify articles published in English within the last 10 years addressing refURS and su-fURS characteristics, clini-cal, and cost data. Relevant studies were then screened, and the data were extracted, analyzed, and sum-marized. The Preferred Reporting Items for Systematic Reviews and Meta-analysis criteria were applied. A narrative synthesis was performed. To date, few studies have properly investigated the issue of costs in ureteroscopy. An important local and international variation in costs exists for both re-fURS and su-fURS in terms of acquisition, maintenance, and repair costs. Reusable scopes have high acquisition and ancillary (e.g. repair, involved personnel) costs, which are not considered in a pure su-fURS activity. However, only recently su-fURS were shown to have a similar efficacy as compared with reusable devices. In high-volume centers, with proper training for reusable ureteroscopes management, the cost per case of reusable and single-use scopes are overlapping ($1,212–$1,743 versus $1,300–$3,180 per procedure). There is a partial overlap in the ranges of costs for single-use and reusable scopes, which makes it important to precisely know the caseload, repair bills, and added expenses when negotiating purchase prices, repair prices, and warranty conditions for scopes.
