The present invention refers to a prosthesis (1) to be used for surgical therapy of female urinary incontinence and urogenital prolapse. Said prosthesis comprises a synthetic or biologic non-reabsorbable or partially reabsorbable mesh (9) and positioning means originating from said mesh (9) and comprising self-locking absorbable or non-absorbable threads (3, 3'), which in combination remarkably reduce the material used, which is subsequently left inside the patient.
