Abstract
Radionuclide hysterosalpingography (RNHSG) was performed to evaluate patency of the fallopian tube in the 16 sterility patients. First, in 3 out of 16 cases, technetium-99m macro-aggregated albumin (MAA) was deposited on the posterior formices of vagina, as described by Iturralde and Venter. But all of the 3 cases did not demonstrate spontaneous migration of Tc-MAA fom the vagina to the uterus and the ovaries. Therefore in the other 13 cases Tc-99m-MAA particles were applied directory onto the internal cervical mucosa through the cervical canal using a syringe with a blunt needle. This method was compared with contrast histerosalpingography (CHSG).
In the evaluation of 26 tubes we found that the accuracy of RNHSG for evaluation of the fallopian tube patency was over 92%. RNHSG could demonstrate functional fallopian tube obstruction in an immobile but anatomically patent tube.
RNHSG is paticulary an attractive method for the evaluation of functional and mechanical tube obstruction in sterility patients.
