Various diagnostic and therapeutic procedures can be performed by using additional accessories, for example disintegration of ureteroliths and kidney stones, biopsy for tumor diagnosis or removal of foreign bodies. ## Device Story Compact Operating Fiber Uretero-Renoscopes and Ureteroscopes are thin, fiber-optic endoscopes designed for visualization of the ureter and kidney. Devices feature an oval channel for irrigation and the simultaneous use of one or two auxiliary instruments; an additional guide is used for lithoclast applications. Available in various lengths, shorter models are used for ureteral procedures, while longer models (uretero-renoscopes) reach the kidney. The devices are operated by physicians in a clinical setting. The physician views the anatomy directly through an eyepiece. The device facilitates diagnostic and therapeutic interventions, such as stone disintegration, biopsy, and foreign body removal, providing clinical benefit through minimally invasive access to the upper urinary tract. ## Clinical Evidence No clinical tests performed. Evidence is limited to bench testing, specifically mechanical load (bending) tests to ensure shaft integrity and validation of optical quality following fractional steam sterilization cycles. ## Technological Characteristics Fiber-optic endoscopes with high-resolution image bundles (up to 30,000 pixels). Features include an atraumatic tip, wide-angle telescope, and an oval irrigation/instrument channel. Designed for steam sterilization (autoclavable). ## Regulatory Identification An endoscope and accessories is a device used to provide access, illumination, and allow observation or manipulation of body cavities, hollow organs, and canals. The device consists of various rigid or flexible instruments that are inserted into body spaces and may include an optical system for conveying an image to the user's eye and their accessories may assist in gaining access or increase the versatility and augment the capabilities of the devices.

The devices have a direct view, an oblique or an offset eyepiece. A single or double instrument port is needed for the insertion of the auxiliary instruments. For lithoclast application an additional guide is used. The longer endoscopes are called uretero-renoscopes and are used for procedures in ureter and kidney. The shorter ones are called ureteroscopes and are used for procedures in ureter (and for procedures in kidney, if the urinary tract is short enough).
