Final answer:
The cystoscope is the specific type of telescope or endoscope used in cystoscopy procedures to examine the bladder and urethra.
Step-by-step explanation:
The most common telescope used for cystoscopy is a cystoscope. A cystoscope is a type of endoscope specifically designed for the urinary bladder and urethra. It allows the doctor to view these internal structures directly and, if needed, perform minor surgical procedures, such as removing a polyp. Unlike telescopes used in astronomy, which gather light from distant celestial objects through lenses or mirrors, a cystoscope transmits light down a fiber bundle to illuminate internal parts, with the reflected light carrying the image back to the physician's eye or a video screen. While other types of endoscopes, like a laparoscope, bronchoscope, and arthroscope, are used for other body cavities and joints respectively, the cystoscope is the specialized tool utilized in cystoscopy.
