Abstract: TBT is a new technique that by use of a balloon catheter technique in a fashion similar to that of balloon angioplasty allows reestablishment of tubal patency in selected cases of tubal occlusion. The case presented here describes the first transcervical dilatation and recanalization of a proximally occluded fallopian tube in a patient with infertility.
