title: Head-mounted display for a personal integrated image monitoring system: ureteral stent placement.
abstract: The personal head-mounted display (HMD) has emerged as a novel image monitoring system. We present here the application of a high-definition organic electroluminescent binocular HMD in ureteral stent placement. Our HMD system displayed multiple forms of information such as integrated, sharp, high-contrast images using a four-split screen or a picture-in-picture technique both seamlessly and synchronously. When both the operator and the assistant wore an HMD, they could continuously and simultaneously monitor the cystoscopic and fluoroscopic images in an ergonomically natural position. Furthermore, each participant was able to modulate the displayed images depending on the procedure. In all five cases, both the operator and the assistant successfully used this system with no unfavorable event. No participants experienced any HMD wear-related adverse effects. We therefore believe this HMD system might be potentially beneficial during ureteral stent placement procedures. Furthermore, it is compact, easily introduced and affordable.
