Transvaginal sonographic evaluation of the retrodisplaced uterus.
To determine the clinical value of transvaginal sonography in the assessment of retrodisplaced uteri, the authors reviewed, retrospectively, 500 consecutive transvaginal (TV) and transabdominal (TA) sonograms. Of the 494 patients examined, 27 had a retrodisplaced uterus. Transvaginal sonography was superior to TA sonography in 25 patients, providing improved visualization of the endometrial canal, myometrium, adnexa and cul-de-sac. In 7 of these 25 patients, the findings that suggested the diagnosis were only seen on TV scanning. These findings included intrauterine pregnancy (three patients), fluid collection in the cul-de-sac (two patients), fluid collection in the endometrial canal (one patient) and an embedded intrauterine contraceptive device (one patient). The two techniques yielded the same information in two other patients. In no patient was TA sonography more informative than TV sonography. The authors, therefore, conclude that TV sonography is the procedure of choice in assessing a retrodisplaced uterus and that additional examination with TV sonography is advisable whenever a retrodisplaced uterus is suspected.
