150 patients were prospectively accrued from January 2016 to November of 2017. Each patient underwent ureteroscopy with either of the aforementioned scopes. After the procedure each surgeon was asked to rate visibility and maneuverability on a 5-point Likert scale (1- Bad, 5- very good). The study team analyzed the comparative data using a fisher’s exact test. All demographic and continuous variables were analyzed using a non-parametric Kruskal-Wallis test or a Mann-Whitney U test.

To conclude, the study team determined that current single-use scopes’ performance are approaching the high-end reusable scopes. They also note that as the cost of single-use scopes continues to decline, while their performance increases, they provide a feasible replacement to reusable scopes during ureteroscopy. This is especially useful in complex stone cases where scope damage is highly likely.
