Dain Medical Group URUS shows lowest workload in ureteroscope study

A comparative study conducted by researchers from the University of California San Diego (UC San Diego) has identified Dain Medical Group’s disposable digital flexible ureteroscope, URUS 1.0, as having the lowest subjective workload among six tested products.

Presented at the 2026 Korean Urological Association (KUA) international conference, the research utilized the NASA Task Load Index (NASA-TLX) to evaluate mental demand, physical demand, time pressure, performance, effort, and stress. In simulation environments mimicking kidney structures, URUS 1.0 recorded a cumulative workload score of 170, which is approximately 56% lower than the highest-scoring product (390) and 45 points lower than the second-lowest product (215).

Regarding navigation efficiency, URUS 1.0 achieved a median completion time of 60 seconds when locating specific positions within the kidney, ranking second fastest among the six products, just one second behind the top performer.

Dain Medical Group noted that while these results highlight the importance of ergonomic design and user convenience, further verification is required to confirm long-term fatigue reduction and clinical effects in actual surgical environments.
