Ureterorenoscopy: current technology and future outlook.

The aim of this paper was to evaluate the current technology and designs of flexible ureterorenoscopes. We will review contemporary fiberoptic and digital ureteroscopes, including a discussion on ureteroscope damage and repair, and lastly present the projected future of flexible ureterorenoscopy. Ureterorenoscopy has evolved dramatically over the past several decades, which has led to landscape reshaping of stone disease treatment and upper tract pathology. Advancements in tip control, miniaturization of scopes, introduction of a digital chip on the tip, disposable devices to augment surgery, surgical experience/familiarity and most recently single use scopes are all independent factors that have increased flexible ureterorenoscopy adoption and success. We therefore detail the aforementioned and provide a view of future innovations. A review of literature from 1980 to 2016 was performed by the two authors focusing on literature that details flexible ureterorenoscopy. Technology has significantly impacted the minimally invasive endourologic management of the urinary system. This review summarizes current literature on advances and modern technical achievements. We include a focus on new perspectives and future outlook in the field of managing upper urinary tract pathology with modern technologies. The advancements in flexible ureterorenoscopy are impressive and yet the challenges of this technology are equally daunting. Obstacles to overcome include improving durability, decreasing cost, further miniaturizing scopes size, and determining the role of single use scopes. Ongoing developments in other technology fields (such as virtual 3D imaging, wireless capsular endoscopy, robotics) continue to create both opportunities to improve the procedure but also threaten to replace ureterorenoscopy over time. This is an exciting time because of past achievements and future innovations in ureterorenoscopy.
