Transvaginal color Doppler sonography versus sonohysterography in the diagnosis of endometrial polyps

OBJECTIVE
To compare the diagnostic performance of transvaginal color Doppler sonography (TVCD) and sonohysterography (SHG) in the diagnosis of endometrial polyps.

METHODS
Fifty-one women (mean age, 51 years; range, 27-75 years) with clinical or B-mode sonographic suspicion of endometrial polyps were included in this prospective study. Transvaginal color Doppler sonography first and then SHG were performed in all patients. On TVCD, a polyp was suspected when a vascular pedicle penetrating the endometrium from the myometrium was identified. On SHG, a polyp was suspected when a focal polypoid lesion was seen within the endometrial cavity. All patients underwent hysteroscopy and endometrial biopsy, the findings of which were used as the criterion standard. Sensitivity and specificity for TVCD and SHG were calculated and compared by the McNemar test.

RESULTS
Hysteroscopy and endometrial biopsy findings were as follows: endometrial polyps, 41; endometrial hyperplasia, 3; cystic atrophy, 4; proliferative endometrium, 2; and endometritis, 1. Sensitivity and specificity for TVCD and SHG were 95% and 80% and 100% and 80%, respectively (McNemar test, P = .5)

CONCLUSIONS
Transvaginal color Doppler sonography and SHG had similar performance for diagnosing endometrial polyps.
