Sonohysterography: Is the Hysterosalpingographic Vacuum Cup a Valid Alternative Device for Cannulation of the Cervical Os?

PURPOSE: To determine whether sonohysterography (SHG) should be performed with Plexiglas hysterosalpingographic vacuum cups instead of standard catheters. MATERIALS AND METHODS: In a prospective setting, 226 women randomly classified into 2 groups underwent SHG. The method used for cervical cannulation was a two-way catheter in the first group (n = 108) and a Plexiglas hysterosalpingographic vacuum cup in the second one (n = 118). Diagnostic reliability, easy applicability for the physician, discomfort for the patients and cost of the instruments were assessed for both devices. RESULTS: 226/226 (100 %) complete sonohysterographic examinations were performed. As regards uterine cavity distension the same diagnostic reliability was reported for vacuum cups and two-way catheters. The standard catheter obscured the cervical canal because of the dilation of the balloon. Both methods were judged as easy to use, and no statistically significant difference was found as far as the time required for cervical cannulation (p 0.05). A little more discomfort was recorded by women who underwent sonohysterography with standard balloon catheters but a greater interpersonal variability was noticed in this group (SD 3.65 vs. 1.13 in the vacuum cup group). Vacuum cups were by far the most economical devices (unit cost: 16.70 euro vs. catheter unit cost 46.20 euro). CONCLUSION: Vacuum cups allow sonohysterography to be correctly performed. As they are inexpensive, easy to use, better tolerated by the patients and more helpful for visualisation of the lower third of the uterine cavity, vacuum cups should be considered a serious alternative to standard catheters in the performance of SHG

Diagnostic utility of combined ultrasonography and mammography in the evaluation of women with mammographically dense breasts.

To assess the diagnostic utility and additional cost of combined breast ultrasonography and mammography in the evaluation of asymptomatic women with mammographically dense breasts. Of 5108 asymptomatic women, who underwent mammography, 1754 had dense breasts (BI-RADS 3 or 4) and negative mammographic outcome. They were divided in 4 subgroups according to their age (59 yrs). Breast ultrasonography was performed immediately after mammography. Lesions detected at ultrasonography were examined cytologically/histologically. Mammograms from women, who were diagnosed carcinoma at ultrasonography, were reviewed by an external radiologist. Costs per diagnosed carcinoma and per examined woman were calculated on the basis of current regional charges. Mammographies (5108) were performed, 67 cancers were detected (cancer detection rate 13.1‰): mammography identified 55 carcinomas and ultrasonography performed in women with dense breasts identified 12 cancers (17.9% of all cancers detected, overall cancer detection rate 6.8‰). Ultrasonography identified a benign condition in 1567 out of 1754 women (89.3%) (in 925 absence of focal lesions; 438 simple cysts; 56 ductal ectasia; 148 benign solid lesions); 97 complex cysts, 52 lesions that could not be differentiated as liquid or solid lesions, and 38 solid lesions suspicious for malignancy in the remaining 187 out of 1754 patients (10.7%). Cytology/histology confirmed carcinoma in 12 women (overall biopsy rate 26.2‰, benign biopsy rate 19.4‰). The additional costs were: € 6,123.45 per detected cancer, € 41.89 per examined woman. Breast ultrasonography immediately after mammography in women with dense breasts is useful to avoid diagnostic delays and inconvenient medico-legal implications even though this procedure involves increased costs
