Hysteroscopic tubal catheterization and hydrotubation for treatment of infertile women with tubal obstruction.

We reported the efficacy of interval hysteroscopic tubal catherization and hydrotubation for three months in 54 infertile women with tubal obstruction (102 fallopian tubes). By comparison of HSGs before and after treatment, 86 of 102 tubes (84%) showed the improvement of tubal patency (P < 0.01). 56 tubes were patent (54.9%). This method is effective for partially patent tubes (87.5%), intramural tubal obstruction (62.5%), and the obstruction at the distal portion of the fallopian tube (13.3). One -12 month follow-up after treatment, 12 of 35 women whose tubes became completely patent achieved intrauterine pregnancies.
