FRANCO, Rodrigo Coelho et al. Endouterine Cavity Investigation: Comparative Study between X-ray Hysterography, Sonohysterography and Hysteroscopy. Rev. Bras. Ginecol. Obstet. [online]. 2000, vol.22, n.10, pp.619-625. ISSN 1806-9339.

Purpose: to compare the methods used to investigate the endouterine cavity by testing the sensitivity and specificity of X-ray hysterography and sonohysterography compared with hysteroscopy (gold standard). Methods: we carried out a prospective study with 18 patients who, due to symptoms such as irregular menstrual cycles, unexplained postmenopausal uterine bleeding and ultrasound disturbance, were candidates for uterine cavity investigation by X-ray hysterography, sonohysterography and hysteroscopy. Results: sonohysterography sensitivity and specificity were 90 and 87.5%, respectively. Positive and negative predictive values were 90 and 87.5%. For X-ray hysterography, sensitivity, specificity, positive and negative predictive values were 70, 75, 77.7 and 75%, respectively. Conclusion: the use of saline instilation into the endometrial cavity in order to enhance the acuracy of the vaginal ultrasonography seems reliable as a mean to distinguish lesions in the uterine cavity, thereby facilitating the identification of candidates for diagnostic or operative hysteroscopy. X-ray hysterography produces results inferior to hysterosonography.
