Objective:
To evaluate selective salpingography sensitivity.
Design:
Retrospective study.
Setting:
Obstetrics and Gynecology Department, University of Genoa, Italy.
Patients:
One hundred seventeen patients previously submitted to selective salpingography because of unilateral or bilateral proximal tubal injection failure.
Results:
Seven pregnancies, one of which was ectopic, were obtained in 17 patients who had only recanalized tubes available for conception; 15 pregnancies were obtained in 39 patients who had one tube recanalized and one already patent; 3 tubal pregnancies were obtained in 12 patients who had only one tube already patent; 4 pregnancies, one of which was ectopic, were obtained in 19 patients who had neither patent nor recanalized tubes.
Conclusions:
Selective salpingography can give false-positive results; therefore, it is possible to obtain a pregnancy even after selective salpingography failure.
