First clinical evaluation of a new single-use flexible cystoscope dedicated to double-J stent removal (Isiris™): a European prospective multicenter study

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.

The Cost

Introduction Isiris α™ (Coloplast®) is an innovative single-use disposable flexible cystoscope with an integrated ureteric stent grasper designed specifically to remove ureteric stents. It allows clinicians to remove ureteric stents easily on the wards or in clinics without the need of arranging a routine and dedicated flexible cystoscopy appointment for patients. We evaluated Isiris α’s practical use and cost analysis against traditional reusable endoscopes. Method We compared the cost of removing ureteric stents using Isiris α™ in 10 patients prospectively versus traditional flexible cystoscopes in 10 patients retrospectively. The costs of the equipment, medications, reprocess machines, and utility costs were consulted from the relevant departments and companies. As for labour cost, we have sourced British Medical Association (BMA) and Royal College of Nursing (RCN) websites. Results From our study, it costs £260.65 and £123.41 on average to remove a ureteric stent using Isiris α™ and traditional flexible cystoscope respectively (p<0.001). Stent removal in the endoscopy department was delayed in 60% of patients, on average 6.4 days, compared to 0% of patients using Isiris α™ (p = 0.048). Conclusion Although Isiris α™ is shown to be a more expensive option to remove ureteric stents based on our analysis, it still provides clinicians flexibility and ease in removing ureteric stents in the outpatient clinic, reducing the pressure and demand for dedicated flexible cystoscopy slots in the endoscopy department.

The Impact

Objective: The objective of this study is to evaluate the costs and benefits of Isiris (Coloplast, Denmark), a mobile, single-use, flexible cystoscope with a built-in stent grasper. Methods: A prospectively collected database was reviewed to define procedural outcomes for Isiris ureteric stent removal. Variables assessed included stent duration and location of removal. A cost assessment was performed evaluating the impact on costs, funding and facility use. Results: Seventy-five procedures were performed using Isiris between April and September 2017. There were no complications. Two procedures failed because of encrustation and poor visibility secondary to haematuria. The mean (SD), median (interquartile range) and range of delay were 2.1 (0–5.3), 0 (0–2) and 0–40 days, respectively. Only one patient was delayed more than two weeks; this occurred because he was placed on a theatre waiting list, which resulted in the 40-day delay. Overall, the cost benefit for our department with the introduction of the Isiris system has been a surplus of $104,434, with an extra 65 elective spaces free for diagnostic flexible cystoscopy cases. Conclusion: Isiris flexible stent removal offers our patients a rapid stent-removal service with low rates of removal delay. Savings have been made in scope repair costs, sterilisation and scope maintenance, as well as optimisation of theatre and procedure room space. Level of evidence: 1c
