The separation procedure for intrauterine adhesion (synechia uteri) under roentgenographic view

For 32 patients with infertility who were thought to have synechia uteri without having any other apparent cause of sterility, the separation procedure of intrauterine adhesion was successfully performed, with the use of an artificial insemination cannula under roentgenographic view while infusing an oleaginous contrast medium of the appropriate viscosity through the cannula. After the operation, two contraceptive intrauterine rings were used, as a rule, for prevention of readhesion. The rings were removed 3 months afterward. Within 2 years after the procedure, successful births were achieved in 18 of 22 patients in whom two rings were inserted, and in 3 of 10 patients in whom only one ring was used.
