[Transvaginal contrast hysterosonography. A new diagnostic procedure for the differentiation of intrauterine and myometrial findings].

In 30 patients with sterility problems, menstrual irregularities, and/or suspected tumor the uterine wall was evaluated by transvaginal hystero-contrast-sonography (CoSy). These findings were compared with those of hysterosalpingography (HSG) or chromo-laparoscopy which were done during the same anesthesia. In 6 patients there was no coincidence, and additional information of relevance could be achieved by the other procedure. One case of submucous and an other of intramural fibroid were exactly differentiated by the transvaginal CoSy. This was not possible by the HSG. In addition two large intramural fibroids were exactly localized by CoSy, where as this couldn't be demonstrated endoscopically. Two uteri arcuati have not been seen by CoSy, but were recognized by HSG. So we recommend the transvaginal CoSy of the uterus as a pretherapeutic procedure for the differentiation and localization of intracavital and myometrial findings. At least at moment it seems to be that the image of light uterine malformations could be better demonstrated by conventional diagnostic methods.
