====== Anatomy and Mechanics of a PVS ======
* '''<span style="color:#ff0000">Positioned at the bladder neck (in contrast to MUS which is placed in the midurethra)</span> to provide urethral compression without obstruction during times of increased intraabdominal pressure.'''
**Pubovaginal slings are placed under mild tension at the bladder neck to reestablish the suburethral hammock and are able to improve SUI by providing a layer of tissue that compresses the urethra during times of increased intra-abdominal pressure.
** Unlike the PVS, the MUS should be placed loosely at the midportion of the urethra to prevent movement of the posterior urethral wall
* The current concept of PVS comes from using a shorter free graft of rectus fascia whose tension could be adjusted
