US evaluation of the uterus in patients with postmenopausal bleeding: A positive effect on diagnostic decision making.

PURPOSE: To assess the accuracy of hysterosonography (HSG) and its role in diagnostic confidence and therapeutic clinical decision making among referring physicians caring for patients with postmenopausal bleeding (PMB). MATERIALS AND METHODS: One hundred twenty-three patients with PMB underwent transvaginal ultrasonography (US) and HSG. They were examined for cancer, polyp, leiomyoma, and hyperplasia. Physicians assessed the effect of the studies on diagnostic confidence and care, including biopsy, dilation and curettage, hysteroscopy, hormone manipulation, and/or patient reassurance. Abnormality was proved with histopathologic evaluation, and normality, with 6-month follow-up. RESULTS: In 10 patients, HSG was unsuccessful, and in 15, follow-up was incomplete; this left 98 patients. Endometrial polyps were seen in 46 (47%) patients; leiomyoma, in 11 (11%); cancer, in four (4%); hyperplasia, in eight (8%); and normal findings, in 29 (30%). Our calculations yielded a sensitivity of 98% and a specificity of 88%. In 86 (88%) patients, US added certainty to the diagnosis; in 78 (80%), it resulted in a change in patient treatment. CONCLUSION: HSG and transvaginal US in patients with PMB improves diagnostic accuracy, clinical decision making, and the clinician's diagnostic certainty. In patients with benign causes of PMB, the absence of abnormality at HSG and a normal endometrial biopsy result may eliminate the need for further studies.

Gynecologic imaging: comparison of transabdominal and transvaginal sonography.

The sonographic findings in 200 patients who underwent concurrent transabdominal and transvaginal pelvic ultrasound were reviewed. The sonographic techniques were compared for image quality, completeness of anatomic detail depicted, and unique diagnostic information. Transvaginal image quality was better in 79%-87% of scans; transabdominal image quality was better in 3%-5% of scans; images of both techniques were equally good in 10%-18% of scans. The techniques provided equivalent diagnostic information in 60%-84% of cases. Transvaginal sonography was particularly helpful when exclusion of ectopic pregnancy was the clinical concern. Individual organs and fine structures were better seen transvaginally, but the regional survey offered by the transabdominal full-bladder approach remains necessary to provide anatomic orientation, particularly when the patient has not been studied previously.

Endometrial abnormalities: evaluation with transvaginal sonography.

The value of transvaginal sonography in detecting gynecologic disease currently is being defined. To evaluate transvaginal depiction of the endometrium, transvaginal sonograms were compared with conventional transabdominal scans in 29 patients whose sonograms revealed endometrial abnormalities. The two techniques were compared for image quality and ability to provide unique diagnostic information. Sonographic findings included fluid collections (16), thickened and/or echogenic endometria (10), endometrial irregularities (two), and echogenic foci (two). Clinical diagnoses included early intrauterine pregnancies (five), pseudogestational sacs of ectopic pregnancy (one), intrauterine contraceptive devices (two), endometrial carcinoma (one), and intrauterine synechiae with amenorrhea (Asherman syndrome) (two). In most cases (77%), diagnostic information was obtainable by either transabdominal or transvaginal sonograms, although in 23% transvaginal scanning provided unique diagnostic information not available with the transabdominal technique. In no case did transabdominal sonography contribute diagnostic information not provided transvaginally. The quality of the transvaginal image was judged to be better than that of the transabdominal image in 63% of cases; image quality was the same in 33% of cases and worse in 3% of cases. The results show that transvaginal sonography is often superior to transabdominal scanning in the evaluation of endometrial abnormalities. Transvaginal sonography may be the preferred technique in these cases.
