[A new technic using polyethylene tubing in oviduct occlusion].

To preserve the tubal patency after tuboplasty the polyethylen prosthesis remains without passing the intramural part of the tube inserted into the ampulla of the tube only ewith a lenght of 3 to 5cm- avoiding decubitus or any other instrumental damage on the tubal lining. The correct insertion of the prosthesis as well as of the tubal patency may be controlled by instillation of a methylen blue solution. After removing the prosthesis the tubal patency would be preserved by hydropertubation with a solution containing antibiotics.
