Introduction: Double J (DJ) stents are frequently used in urologic practice and are removed using a rigid or flexible cystoscope with a stent removal forceps or a foreign body forceps and video cystoscopy is often helpful.We report here a technique for cystoscopic removal of the stent when the instruments, equipment and machines for video cystoscopy are expensive and not readily available in some hospitals. Sohn et.al., in 2013, developed “Endockscope” which connects flexible endoscope but only with Apple iPhone 4S smartphone. Our study aims to demonstrate how to connect any Android, Apple or Windows smartphone with any cystoscope using commercially available universal “digiscoping” adapters during video cystoscopic DJ stent removal.
Methods: A vertical screw-in type “digiscoping” adapter Gosky smartphone adapter - model number: QHAP002 was used in our study. It was connected to an Android “camera-smartphone” Redmi note 4. When camera of smartphone was carefully aligned to telescope which was fitted with shims, DJ stent images viewed on screen of smartphone can be focused and zoomed in for desired size. DJ stent images viewed on screen of smartphone, as well as images simultaneously viewed with wireless “screen mirroring” in laptop monitor, were noted to be acceptable in video cystoscopy. Photographs of endoscopic DJ stent images were taken for review and then DJ stent was removed.
Results: This technique has been tried in 10 female patients at our institute. Of these, 4 had bilateral DJ stent. The stent could be removed in all the patients without any procedure-related complication.During “wireless screen mirroring,” there appears to be some delay in viewing image in laptop monitor compared to image from screen of smartphone.
Conclusions: Smartphone can be connected with cystoscope using commercially available universal “digiscoping” adapters during DJ stent removal. DJ stent images viewed from screen of smartphone or simultaneously in laptop monitor, as well as photographs of cystoscopic images, were acceptable during removal. Source of
