Which instrument is used during a cystoscopy?

The cystoscope is specifically designed for the procedure in which a physician examines the inside of the bladder and urethra. This instrument allows for direct visualization and can be used for diagnosis, treatment, or biopsy during a cystoscopy. The cystoscope is equipped with a light and camera, enabling the healthcare provider to get a clear view of the urinary tract.

Unlike the stethoscope, which is used for listening to internal body sounds such as heartbeats and lung sounds, and the ultrasound, which uses sound waves to create images of internal organs, the cystoscope serves a distinct purpose. The endoscope is a general term for an instrument used to visualize the interior of a bodily canal or hollow organ but does not specify the particular feature needed for a cystoscopy procedure. Thus, the cystoscope is the correct instrument associated with this specific medical procedure.
