FEITOSA, Iêda Maria Silveira Diógenes et al. Comparison between transvaginal ultrasonography and sonohysterography in the assessment of patients with abnormal uterine bleeding. Radiol Bras [online]. 2011, vol.44, n.3, pp. 156-162. ISSN 0100-3984. http://dx.doi.org/10.1590/S0100-39842011000300007.
OBJECTIVE: To comparatively evaluate the effectiveness of transvaginal ultrasonography (TVUS) and sonohysterography (SHG) in the assessment of endometrial diseases in women with abnormal uterine bleeding. MATERIALS AND METHODS: Cross-sectional study with 30 patients, aged from 29 to 71 years, 21 (70%) of them premenopausal and 9 (30%) postmenopausal. Saline solution (at 9%) was utilized as contrast agent for SHG. The MacNemar test was utilized for comparison of diagnostic studies. RESULTS: Hysteroscopy diagnosed 18 cases (60%) of intracavitary alterations, and 10 polyps (33.3%). TVUS demonstrated 83.3% sensitivity and specificity, and SHG showed 94.4% sensitivity and 91.6% specificity. The MacNemar test showed similar sensitivity (p = 0.500) and specificity (p = 1.000) between TVUS and SHG in the detection of endometrial diseases. In the diagnosis of polyp, SHG showed the highest sensitivity (90.9% vs. 27.3%; p = 0.016) with similar specificity (89.5% vs. 94.7%; p = 1.000). CONCLUSION: SHG and TVUS present a good predictive value for endometrial diseases in patients with abnormal uterine bleeding. SHG and TVUS present similar sensitivity and specificity in the detection of such diseases, but SHG is more sensitive in the detection of polyps.
