To assess the degree of dysfunction, three measurements must be 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 provides a measurement of pelvic floor descent, with descent greater than 2 cm being considered mild, and 6 cm being 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 of 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 of organ prolapse relative to the hiatus is more strict, with any descent being considered abnormal, and greater than 4 cm being considered severe.
Your pelvic floor is the group of muscles and ligaments in your pelvic region. The pelvic floor acts like a sling to support the organs in your pelvis — including the bladder, rectum, and uterus or prostate. Contracting and relaxing these muscles allows you to control your bowel movements, urination, and, for women particularly, sexual intercourse.
By definition, postpartum pelvic floor dysfunction only affects women who have given birth, though pregnancy rather than birth or birth method is thought to be the cause. A study of 184 first-time mothers who delivered by Caesarean section and 100 who delivered vaginally found that there was no significant difference in the prevalence of symptoms 10 months following delivery, suggesting that pregnancy is the cause of incontinence for many women irrespective of their mode of delivery. The study also suggested that the changes which occur to the properties of collagen and other connective tissues during pregnancy may affect pelvic floor function.
Pelvic floor dysfunction is a common condition where you’re unable to correctly relax and coordinate the muscles in your pelvic floor to urinate or to have a bowel movement. If you’re a woman, you may also feel pain during sex, and if you’re a man you may have problems having or keeping an erection (erectile dysfunction or ED). Your pelvic floor is a group of muscles found in the floor (the base) of your pelvis (the bottom of your torso).
The “pelvic floor” refers to a group of muscles that attach to the front, back, and sides of the pelvic bone and sacrum (the large fused bone at the bottom of your spine, just above the tailbone). Like a sling or hammock, these muscles support the organs in the pelvis, including the bladder, uterus or prostate, and rectum. They also wrap around your urethra, rectum, and vagina (in women).
