Radionuclide hysterosalpingography does not distinguish between fertile women, before tubal sterilization, and infertile women.
The female genital tract is capable of active transport that can be demonstrated by serial scintigraphic imaging over time (radionuclide hysterosalpingography; RN-HSG). RN-HSG has been suggested to offer a more functional approach to tubal infertility diagnosis than conventional patency tests. However, before RN-HSG can be recommended as a routine method, its reliability in showing active transport in fertile women must be demonstrated. Therefore we compared RN-HSG in two groups: 38 fertile women before tubal sterilization and 38 women undergoing infertility work-up. Tubal transport demonstrated by RN-HSG was comparably distributed in both groups and classified as bilateral (17 versus 19), unilateral (12 versus 7) or no transport (6 versus 9). In each group three RN-HSG images were not interpretable. There was no association between patency test results and RN-HSG in the two groups. Our data suggest that RN-HSG in its present form does not seem to be a reliable method for infertility work-up. Because RN-HSG and patency tests most probably measure different properties of the genital tract, the phenomenon of active particle transportation should be studied further to enable the development of a reliable tool for the investigation of tubal function.
