ABSTRACT:
A catether prosthesis for medical-surgical application, of silicone material, is manufactured by mass-production, and its positioning in the patient is made rapid, easy and painless by inserting into its stem an insert, also of silicone material, which is removed by withdrawing it after cutting the stem to the length required to be inserted into the ureter; said stem, which is of considerable length, it provided with density distributed drainage holes, and with tongues for locking it in position.
