• Valuable diagnostic information about the cervical canal and the cavum corporis uteri can be obtained by direct inspection with a water hysteroscope. Photographs can be made by attaching an endoscopic camera.
Water, under pressure controlled by gravity, is allowed to flow freely into the hysteroscope on the right side, to circulate in the lumen of the uterus, and to flow out on the left side. When an observation is to be made, the outflow on the left side is interrupted momentarily. It is possible to visualize the two cornua up to the openings of the uterine tubes.
The first photographs of the interior of the uterus have been made in this way. The technique has been used for seven years without ensuing complications.
