Frequency of Proximal Tubal Obstruction in Patients Undergoing Infertility Evaluation

Abstract

Fallopian tube recanalization is a technique for treatment of proximal tubal obstruction caused by debris. The true frequency of infertile women for whom this treatment is suitable is not well known. In this study all hysterosalpingograms (HSGs) performed over a 3-year period (1986–88) were reviewed. The HSGs were performed as part of an infertility evaluation program in 494 women, with a mean duration of infertility of 2.4 years. Bilateral proximal tubal obstruction was found in 3% and unilateral proximal obstruction in 2% of the cases. In women examined in the first 2 years (1986–87) (n = 328), the birth frequency after HSG was 25%. When HSG was performed with optimal technique the number of patients who were suitable for Fallopian tube recanalization was low.
