Confirmation of tubal patency in hysterosalpingo-contrast sonography by transvaginal hydrolaparoscopy.
OBJECTIVE
To confirm tubal patency in hysterosalpingo-contrast sonography (HyCoSy) by transvaginal hydrolaparoscopy (THL).


METHODS
A prospective study.


METHODS
Infertility clinic at a university hospital.


METHODS
Fifty-six infertile women with a history of tubal risk factor(s) who underwent HyCoSy and THL between 2003 and 2006.


METHODS
After performing HyCoSy, the tubal patency was verified by THL.


RESULTS
Altogether, 51 women and 101 tubes could be examined. Using HyCoSy, 61 of the tubes were considered patent and 40 occluded. THL confirmed 82 tubes patent and 19 occluded. Of 61 tubes found to be patent in HyCoSy, 60 were also patent in THL. In contrast, of 40 tubes occluded in HyCoSy only 18 tubes were confirmed to be occluded by THL. The concordance was 77%. The sensitivity of HyCoSy was 95%, the specificity 73%, the negative predictive value 98% and the positive predictive value 45%.


CONCLUSIONS
HyCoSy is a reliable method when tubal patency is demonstrated. In cases of suspected tubal occlusion, THL is an inexpensive and safe outpatient procedure to exclude benign tubal spasm and confirm the presence of true occlusion.
