The goal of a diagnostic hysteroscopy is to visualize the uterine cavity and evaluate it for pathology. A biopsy may also be performed during the hysteroscopy. In this film the various parts of the diagnostic hysteroscope, its assembly, introduction into the uterus and how it is then handled are demonstrated. The specific hysteroscope shown in this film is equipped with a continuous flow system that allows for the continuous in- and outflow of distension medium as well as a working channel allowing for the introduction of instruments. Various types of hysteroscopes exist however and a hysteroscopy may also be performed with a single flow hysteroscope without a working channel. Diagnostic hysteroscopies may be performed in an ambulatory care setting or in theater.
