of the rectum is referred to as a rectocele, bladder prolapse through the anterior vaginal wall is called a cystocele, and prolapse of the small bowel is an enterocele. To assess the degree of dysfunction, three measurements are taken into account. First, an anatomic landmark known as the pubococcygeal line must be determined, which is a straight line connecting the inferior margin of the pubic symphysis at the midline with the junction of the first and second coccygeal elements on a sagittal image. After this, the location of the puborectalis muscle sling is assessed, and a perpendicular line between the pubococcygeal line and muscle sling is drawn. This line provides a reference point for the measurement of pelvic floor descent. Descent greater than 2 cm below this line is considered mild and descent greater than 6 cm is considered severe. Lastly, a line from the pubic symphysis to the puborectalis muscle sling is drawn, which is a measurement of the pelvic floor hiatus. Measurements greater than 6 cm are considered mild, and greater than 10 cm severe. The degree of organ prolapse is assessed relative to the hiatus. The grading for organ prolapse relative to the hiatus is more strict. Any descent below the hiatus is considered abnormal, and descent greater than 4 cm is considered severe. Ultrasound can also be used to diagnose pelvic floor dysfunction. Transabdominal, transvaginal, transperineal and endoanal ultrasound (EUS) are important tools for diagnosing pelvic floor dysfunction. For EUS, an ultrasound probe is inserted into the anal canal and can be used to visualize and assess the anatomy and function the pelvic floor. Ultrasound is easily accessible and noninvasive; however, it may compress certain structures, does not produce high-quality images and cannot be used to visualize the entire pelvic floor. Treatment There are several approaches to treatment of pelvic floor dysfunction, and often several approaches are used in combination. Physical therapy Pelvic floor muscle (PFM) training is vital for treating different types of pelvic floor dysfunction. Two common problems are uterine prolapse and urinary incontinence both of which stem from muscle weakness. Pelvic floor muscle therapy is the first line of treatment for urinary incontinence and thus should be considered before more invasive procedures such as surgery. Being able to control the pelvic floor muscles is vital for a well functioning pelvic floor. Without the ability to control the pelvic floor muscles, pelvic floor training
