[Endocurietherapy in cancer of the bladder. A new technique by implant of 192iridium with Cyponil tubes (author's transl)].

The Authors propose a new technique of interstitial implant in cancer of the bladder based on the direct implant of 192 Iridium with Cyponil tubes. The tubes are roughly 2 metres in length with a radioactive wire in one third of the tube length. These wires are kept in a lead container during the complete implantation of the tube. After opening the bladder the uncharged part of the tube is passed through the inner walls by means of surgical needles. The number of the tubes depends on the size of the tumour and they are placed parallel to each other. They are then drawn until the radioactive part covers the tumour site. One end of the Cyponil tube is then pulled through the urethra and stitched to the skin, the other end is drawn through the surgical incision and attached to the abdominal skin. A Folley catheter is put on the bladder is such a way as to keep it blown up. It is then sutured. A radiography is carried out so as to determine the dosage. At the end of the therapy the stitches of the Cyponil tubes are cut and are removed by extraction.
