The invention concerns an implantable prosthesis (1) for the treatment of incontinence, comprising a retaining means (2) having a support element (3) designed to be placed under the urethra (U) and to prevent any uncontrolled intraurethral flow, said prosthesis being characterized in that it comprises an atraumatic suspension means (4) provided with at least one bearing element (5) arranged so as to overlap part of the pubic bone (OP) and to rest on the latter, and at least one sling (6, 7) connecting said bearing element (5) to the retaining means (2), said sling (6, 7) being designed to hold the support element (3) at a substantially constant distance from the public bone (OP), called the retaining distance (do), a means (20) for reversibly adjusting the retaining distance (do), thus making it possible to reversibly vary said retaining distance (do). The prosthesis is used to treat incontinence.
