costs but might affect the lifespan of reusable instruments. Isiris was more rentable in institutions where JJ removal is usually performed in the EnR/OR, allowing to perform the procedure in outpatient clinic, with a significant saving of money (from 41€ to 1.140£ per procedure) and EnR/OR time that could be dedicated to other activities. Despite the fact that in the only institution where JJ removal is done in outpatient clinics with reusable scopes there was a slight cost benefit in favor of reusable material, Isiris provides that a sufficient number of cystoscopes is always available to guarantee an effective turnover. CONCLUSIONS: Isiris leads to significant cost benefit in the institutions where JJ removal is routinely performed in EnR/OR, both in terms of money saved and EnR/OR time saved for other procedures.
