[The double contrast hysterography using CO2 insufflation (author's transl)]

The double contrast hysterography, which was performed by the continuous CO2 insufflation with the ordinary HSG, was applied to 162 infertile patients. Forty-nine of 162 patients showed the abnormal findings by this method. Hysteroscopic or histological examinations revealed that 26 of these patients had hyperplasia, 15 had polyp, 2 had myoma and 1 had intrauterine foreign body. When these results were compared with those obtained by ordinary HSG, it was found that the double contrast hysterography would be more useful to investigate the detailed intrauterine changes such as hyperplasia or polyp than the ordinary HSG, and, therefore, would be a useful aid in the clinical care.
