urethroscope
This is a small rigid telescope which may be passed up the urethra to view the state of the urethral wall and prostate gland. It differs from a cystoscope because it has an end rather than a side view. This type of Endoscope, sometimes called a panendoscope, does not normally have extra channels for the passage of surgical instruments, although it must be possible to infuse fluids to create a small viewing space at the end.
