New Publication: Disposable ureteroscope is safe and may shorten procedure duration

Dr. Manint Usawa, Dr. Thomas Chi and their colleagues from the UCSF Departments of Urology recently published a case-cohort study comparing two groups of patients undergoing flexible ureteroscopy for upper urinary tract pathology. The first group (115 patients) underwent surgery utilizing a disposable ureteroscope called LithoVue, and the second group (65 patients) used reusable fiber-optic flexible ureteroscopes.

The research team found that LithoVue can reduce procedure time for over 10 minutes while preserving excellent clinical outcomes (54.1+/- 25.7 minutes compared with 64.5+/-37.0 minutes). Scope failure occurred in 4.4% of LithoVue cases and 7.7% of reusable cases, which were not statistically significant. This data suggest that LithoVue represents a feasible safe alternative to reusable flexible ureteroscopes. Compared with the reusable fiber-optic flexible ureteroscope, LithoVue use was associated with a shorter procedure and overall operating room duration. However, these findings warrant further investigation.

Impact of LithoVue use on procedure duration and hospital stay. Mean procedure duration decreased from 64.5 – 37.0 to 54.1 – 25.7 minutes ( p < 0.05) for all procedures.
