Abstract

OBJECTIVE
To evaluate the efficacy of sonohysterography on exact submucosal myoma.
methods
Transvaginal sonohysterography was performed on 45 patients who diagnosed as submucosal myoma and 29 patients who diagnosed as endometrial polyp by classic abdominal or vaginal sonogram, and then they received the diagnostic hysteroscopy at all.
RESULTS
In 24 of 45 patients on sonohysterogram, submucosal myoma was diagnosed that was protruded to uterine cavity more than 2/3 of mass. Nine patients had intramural myoma and 12 patients had myoma that protruded only lesser than 1/3 of mass on sonohysterogram. These 21 patients revealed the same finding on hysteroscopy. On hysteroscopy, submucosal myomas were in 20 of 24 patients and polyps were in 3 patients and synechia was in one patients. In 8 of 29 patients on sonohysterogram, endometrial hyperplasia was found and confirmed by hysteroscopy. In 16 of 21 patients whose finding was polyp on sonohsyterogram, polyp was confirmed by hysteroscopy. However hysteroscopic findings were myomas in 3 of 21 patients and synechia in one patients. Therefore in 29 of 74 patients (39.2%), further hysteroscopy was not needed by sonohysterogram. In 65 of 74 patients (87.8%), sonohysterographic findings were same as hysteroscopic findings.
CONCLUSION
Sonohysterogram for diagnosis of submucosal myoma and polyp is essential procedure in order to avoid unnecessary hysteroscopy. However differentiation between polyp and submucosal myoma has still some difficulty.
