[New aspects in therapy of proximal tubal occlusion: hysteroscopic proximal tubal catheterization].

To date, the therapy of first choice in case of proximal tubal pathology is resection of the occluded segment and microsurgical reconstruction. Essential disadvantage of this rather successful method consists in the need of a laparotomy. According to the concept of minimal invasiveness a pilot study has been undertaken to evaluate hysteroscopic proximal tube catheterization (HPTC) and balloon dilatation for recanalization. This attempt has proven intraoperatively successful in more than 80% of the cases and the first pregnancy and birth following HPTC can yet be reported.
