Hysteroscopic tubal catheterization in patients with proximal tube obstruction, was successful in our material in 11 out of 15 cases. In 36.6% women this pathology was connected to the presence of pathologic microflora in the oviducts, as confirmed by bacteriological examination of tubal fluid. The pregnancy rate in endoscopically treated patients reached 13.3%. Three months follow-up HSG showed that in 78% of cases insertion of a catheter into their oviducts resulted in their complete patency. Hysteroscopic tubal catheterization failed in 4 women, who were subsequently qualified to IVF. The present study shows that hysteroscopic tubal catheterization in patients with proximal tubal obstruction can be used both as a diagnostic and considerably effective therapeutic method.
