Purpose: to determine the role of sonohysterography in the evaluation of abnormalities in the uterine cavity in patients presenting abnormal uterine bleeding, who had previously been selected by transvaginal ultrasonography. Methods: forty-eight patients presenting abnormal uterine bleeding and changes in the uterine cavity seen by transvaginal ultrasonography were selected, and they were in the menacme or postmenopause period. All patients underwent a sonohysterography, and later a hysteroscopy and/or a hysterectomy. The sonohysterographies were evaluated by two different physicians, and the diagnoses were compared. Results: the sonohysterography method showed high sensitivity and specificity for the diagnosis of benign pathologies in the uterine cavity. First, in the presence of polyps the sensitivity and specificity rates were 100 and 97%, respectively, second, in the presence of submucous myoma, they were 83 and 100%, and finally, concerning endometrial hyperplasia and normal endometrium, they were 100%. We diagnosed thirty-three cases of polyps, thirteen cases of submucous myoma, four cases of endometrial hyperplasia and three normal cases. The correlation between the diagnoses provided by the two physicians was high. Conclusions: sonohysterography is a safe and fast method which is very well tolerated by the patient, and has low levels of complications. Its high sensitivity and specificity allow this method to be used for routine diagnosis concerning benign pathologies in the uterine cavity of patients presenting abnormal uterine bleeding.

PURPOSE: to analyze the accuracy of sonohysterography for the evaluation of the uterine cavity in patients with an implantation failure, at the first attempt of an in vitro fertilization cycle. METHODS: in a prospective double blind study, the authors analyzed patients previously submitted to at least one embryo transfer, who presented implantation failures. The patients were submitted to a sonohysterographic examination followed by a diagnostic hysteroscopic examination, carried out by different professionals each of whom was not aware of the results of the other. The results were recorded and only interpreted after the end of the trial. Sonohysterography was performed by the introduction of a urethral catheter 8 into the uterine cervix followed by infusion of physiological saline. The anechoic interface shown by the physiological saline can reveal abnormalities, like uterine polyps or submucosal myomas. Hysteroscopy was performed with a Karl Storz equipment, 4 mm 30º rigid telescope, and infusion of physiological saline for uterine cavity distention. RESULTS: twenty-eight of the 33 originally selected patients for this study were analyzed. Sonohysterography detected abnormalities in 8 patients, five with endometrial polyps (62.5%), two with endocervical polyps (25.0%), and one with submucosal myoma (12.5%). Hysteroscopy (gold standard) detected abnormalities in 7 patients, two with endometrial polyps (28.6%), two with cervical polyps (28.6%) and one with submucosal myoma (14.2%). Sonohysterography, when compared with diagnostic hysteroscopy, presented 71.4% sensibility, 85.7% specificity, 62.5% positive predictive value, and 90% negative predictive value of. CONCLUSION: due to its low positive predictive value, the authors suggest confirmation of the sonohysterography result by diagnostic hysteroscopy. Because sonohysterography presents a good level of specificity and a favorable low negative predictive value, the authors suggest that after a normal sonohysterography diagnostic hysteroscopy to evaluate the uterine cavity before in vitro fertlization is not necessary. This study leads to the conclusion that sonohysterography is a good screening method for the detection of polypoid lesions of the uterine cavity, which could be responsible for implantation failures in in vitro fertilization cycles.

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.

Purpose: to evaluate the diagnostic accuracy of sonohysterography as a diagnostic method for the evaluation of the uterine cavity in postmenopausal women with abnormal uterine cavity at conventional endovaginal sonography. Methods: this study consisted of the evaluation of 99 postmenopausal patients with abnormal uterine cavity on conventional endovaginal sonography, that was defined as endometrial thickness equal to or larger than 5 mm in a postmenopausal patient not on hormone replacement therapy, or endometrial thickness equal to or larger than 8 mm in patients on hormone replacement therapy, with irregular bleeding. These patients were subjected to sonohysterography, and specimens were obtained for pathologic examination by biopsy guided by histeroscopy in 92 patients, endometrial biopsy in four patientes and hysterectomy in three patients. The results of sonohysterography were compared with the pathologic findings, considered "gold standard". Results: there were eight cases of normal uterine cavity and 20 cases of atrophic endometrium and sonohysterography had high levels of specificity (97.8 and 97.5%) and low sensitivity (35 and 25%). There were high levels of sensitivity (92.3 and 75.0%) and specificity (94.1 and 97.9%) for polyps (65 cases) and submucous myomas (four cases). There were three cases of endometrial carcinoma and the sonohysterography had a sensitivity and specificity of 100%. Conclusions: sonohysterography showed to be accurate in the diagnostic of focal diseases (endometrial polyps and submucous myomas). There were three cases of endometrial cancer, and sonohysterography correctly diagnosed all of them. This method was also accurate to exclude endometrial abnormality. However, in the cases of diffusely thickened endometrium, the accuracy was low, because atrophic and normal endometrium on histopathology frequently appears as diffusely thickened endometrium at endovaginal sonography and sonohysterography. Sonohysterography did not lead to complications during and after the procedure.
