3D endovaginal ultrasound image of an incontinence sling at the level of the external urethral meatus

3D EVUS image of the right mid-sagittal view of the anterior compartment showing a caudal incontinence sling (asterisk) at the level of the external urethral meatus. In measuring the urethra with ultrasound, the vesicourethral junction is the 0th percentile, and the external urethral meatus is the 100th percentile. The mid-sling location is measured from the vesicourethral junction, and this measurement is divided by the total length of the urethra.
