Introduction and objective: The novel single-use digital flexible cystoscope Isiris™ has been developed to perform in-office JJ stent removal, without the need of special equipment nor limitations linked to the disinfection of a reusable device. The aim of our study was to perform a cost-effectiveness analysis of Isiris™ in our institution. Patients and methods: A total of 127 consecutive patients undergoing in-office stent removal with Isiris™ were prospectively included in study. After each procedure, the urologist filled a questionnaire specifically developed to evaluate the efficiency of the device and the invasiveness of the procedure. We performed a cost analysis of the main variables involved in JJ removal using Isiris™ versus the traditional Storz™ reusable flexible cystoscope used for all our previous patients. Results: The procedure was successful in all cases except for one, where the device did not work due to the failure of the grasper and had to be replaced. Overall, the performance of Isiris™ was judged by the physician “very good” and “good” in 90.6% of the cases. Both median pain and invasiveness felt by the patient were 0 (range = 0–8). The mean cost of procedure was estimated at €361 for in-office stent removal with Isiris™, and €1.126.8 for stent removal in operatory room with a reusable flexible cystoscope. Considering the 127 procedures performed in office, 64 h of operatory room time was saved. Conclusion: In institutions where JJ removal is performed in the operatory room, Isiris™ leads to a significant advantage in terms of money saved per procedure, operatory room time gained and patient satisfaction.
