The single-use ureteroscope/pyeloscope is a medical device designed for examination and treatment of the urinary system. Its single-use design avoids cross-infection risk and improves patient safety. The endoscope is generally made from flexible materials so that it can follow the body's natural lumen and reduce tissue injury. A high-resolution camera and light source at its distal end transmit HD images to an external display in real time, helping clinicians observe lesions in the renal pelvis, ureter, and related areas and assist with procedures such as stone removal and tissue biopsy.
