MRI is the ability to visualize the three compartments of the pelvic floor concomitantly. However its greatest advantages were the high soft tissue resolution that allows direct visualization of the urethral supporting structures (muscles, fascia and ligaments) in order to pinpoint the anatomical defects leading to urinary incontinence by static MRI images. Moreover it is non invasive and lacks ionizing radiation. However the less physiologic supine position during imaging and high cost remained a major disadvantage.Recently transperineal ultrasound has evolved as a new promising method of investigating females complaining of urinary incontinence. It also lacks ionizing radiation. Its wide availability, lower price and shorter duration of examination have encouraged many researchers to study its capabilities yet an overall knowledge of pelvic floor ultrasonography is not widespread. Transperineal ultrasound is relatively easy to perform technique for the assessment of urethral morphology and relationship of the urethra with bladder and pubic symphysis. The application of ultrasonography is mainly subject-related and the diagnostic accuracy depends mainly on the experience and ability of the investigator.
