The performance of hysterosalpingo contrast sonography (Hy Co Sy) as a
first-line, outpatient investigation of tubal patency was examined in 500
consecutive, infertile women, at one centre. Hy Co Sy was completed in 463
(92.6%) cases, using a galactose microbubble contrast agent (Echovist-200)
and transvaginal sonography. Initial plain scanning identified adnexal
pathology in 198 women (39.6%). Examination with Echovist was attempted for
905 tubes and only 67 (7.4%) were not assessable; after the first 100 women
this decreased to 35 tubes (4.8%). A sonographic appearance compatible with
blocked tubes was found on 118 (14.1%) occasions but it was also possible
to identify variations in the appearance/filling/spilling patterns of
individual tubes which increased the number assessed as abnormal to 193
(23.0%). Comparison with laparoscopy and dye chromopertubation findings
from the past three years was possible for 185 (37%) women, representing
282 tubes, which gave Hy Co Sy an overall concordance rate of 85.8%,
sensitivity of 90.4%, specificity of 70.3%, positive predictive value of
91.2% and negative predictive value of 68.2%. Some 51.0% of women described
only mild discomfort and there were no significant postprocedure
complications. Hy Co Sy appears to be an acceptable first- line screen and
may select out women in whom more invasive investigations are likely to
reveal pathology.
