The objective of this study was to compare the costs of stent removal in an outpatient clinical environment between the single-use Isiris system (Coloplast, Denmark) to our existing approach using a reusable cystoscope and stent grasper. METHODS: The number of stent removal procedures at our tertiary center was recorded as a proportion of all cystoscopic proced- ures performed between February 2016 and February 2017. Elements included in the micro-cost assessment included: the original purchasing price of an Olympus digital reusable cystoscope, repair fee (based on a one year contract), sterilization equipment and accessory costs, reprocessing costs of the cystoscope, and labor costs.
