The role of contact hysteroscopy.

Contact hysteroscopy has been replaced by a new technique based on the use of a special hysteroscope. The instrument was designed to study the squamocolumnar junction and the lesions of the portio. A new technique, endometrial dating, uses the Hamou hysteroscope to study endometrial physiology. We improved endometrial dating and discovered a new pattern, the pseudofunctional dysvascular endometrium (PFDE), that seemed to pertain to uterine bleeding. We also studied the PFDE syndrome in the presence of dysfunctional uterine bleeding. In this study we reviewed the three procedures and assessed their results. We conclude that contact microhysteroscopy is a reliable diagnostic procedure, and should be considered part of diagnostic hysteroscopy, not an independent technique.
