Comparison of Hysterosalpingography with Laparoscopy and Chromopertubation.

We compared two methods of determining tubal patency. Between January 1, 1993, and December 31, 1994, 55 women were evaluated for infertility by laparoscopy and chromopertubation and either traditional hysterosalpingogram (HSG; group 1, 25 patients, 16 primary, 9 secondary infertility) or a mixture of Hy-Co-Sy with Echovist (group 2, 30 patients, 14 primary, 16 infertility). In group 1 HSG showed 64% bilateral patency, 8% unilateral patency, and 28% bilateral occlusion; laparoscopy and chromopertubation showed 72%, 8%, and 20%, respectively.
