DOI: 10.1089/end.2022.0195
Abstract: PURPOSE Digital ureteroscopes employ "chip-on-the-tip" technology which allows for significant improvement in image resolution. However, image distortion often occurs during laser lithotripsy due to acoustic wave production. We sought to compare image distortion using different… read more here.
