    How do ureteroscope types compare ergonomically?

    Findings of a study investigating biomechanical stresses on the urologist while performing flexible ureteroscopy indicate that reusable and single-use digital ureteroscopes have a more favorable ergonomic profile than a reusable fiberoptic instrument.

    The study, which employed electromyography to quantify the activation level of muscle groups used during ureteroscopy, was conceived by senior author Brian R. Matlaga, MD, MPH, of The James Buchanan Brady Urological Institute, Johns Hopkins School of Medicine, Baltimore. It was presented at the World Congress of Endourology and SWL in Vancouver, Canada, and recently published online in the Journal of Endourology (Aug. 17, 2017).

    “A large number of urologists spend a significant amount of time performing ureteroscopy. The ergonomics of the procedure has never been formally evaluated, but we considered it worth investigating as urologists performing multiple cases can develop muscular fatigue,” said Wesley Ludwig, MD, MS, of The James Buchanan Brady Urological Institute.

    “Our aim is to improve the ergonomics of ureteroscopy because we believe that efficiency and quality will likely improve if the urologist can operate for longer periods of time more comfortably.”
