A new technique for curing urinary stress incontinence using the vaginal route and a sling of synthetic material, GORE-TEX, is described. The sling is fixed at one end on the junction between the cervix and the urethra in the centre, and at the edges to the tendons of the pubo-coccygeal muscles. The situation is worked out from a urethral profile. Thirty cases have been treated and the results have been satisfactory. If they are confirmed by other operators it will show that a new reliable technique which is very simple and non-aggressive can be used.
