Comparison of Optical Resolution With Digital and Standard Fiberoptic Cystoscopes in an In Vitro Model

Digital Nephroscopy: The Next Step

“…When compared to fiberoptic scopes, the digital image has significantly higher resolution with an effective pixel count of 12 times greater than fiber optic scopes. 2,3 However, there is no difference in the image quality between this digital nephroscope when compared with Hopkins rod-lens nephroscope.…”

In Vitro and In Vivo Comparison of Optics and Performance of a Distal Sensor Ureteroscope Versus a Standard Fiberoptic Ureteroscope

“…2,7 The introduction of distal sensor technology in cystoscopes has led to a significant improvement in visual optics. Distal sensor technology does not require white balancing and camera focusing; it also eliminates the need for an external camera and light source, which significantly reduces the weight of the ureteroscope.…”

New technology in the treatment of nephrolithiasis

“…This new technology has also introduced other possible advantages, including improved optical characteristics, obviating focus and white-balancing issues, and decreased surgeon fatigue without cumbersome proximal camera and light cord attachments. Quayle et al [1] reported on the optical performance the new 'chip on a stick' technology as it applied to flexible cystoscopes in vitro, demonstrating improved visibility compared to fiber-optic flexible cystoscopes.…”
