An efficient, safe, and reproducible surgical technique for the treatment of female stress urinary incontinence, in which the anchor consists of removable string so that no string remains inside the body after positioning, fixation and adjustment of the sling in the target place during surgery and thus minimizing the subjects discomfort after placement of the sling. Thus allowing removal of the string from the passage of the anchor for short sling system. The short and long sling system further comprises fixation of the bearing, ring and the attachment that allows for anti-twisting element to provide better flexible attachment of the sling with the delivery device facilitating relative rotational motion of the bearing with the ring and the attachment but preventing axial displacement of the bearing with the attachment. [0035] The invention further contains a device which allows attachment of the sling with the delivery device by threading/screwing during assembly. This invention relates to a method of placing the sling in a position beneath the urethra by transobturator approach using small incision through the marked position at the vaginal epithelium, beneath the level of mid-urethra, as per standard procedure for a midurethral sling for inside-out approach and making a thigh incision at the marked position, placing the sling beneath the mid-urethra through transobturator approach outside-in approach. This procedure involves for both long sling system and short sling system.
