MODEL RELEASED. Pelvic floor repair. View of surgeons repairing a woman's pelvic floor. The pelvic floor is the lower wall of the abdominal cavity. It may be damaged in several ways. A hernia usually involves the projection of an organ (typically part of the intestine) through the abdominal wall. The hole then has to be sewn together. Damage to the pelvic floor may also be caused by difficult childbirth, or by surgery which involves the organs attached to the floor (such as the bladder and uterus). Repair is usually carried out by stitching the damaged area together to promote natural healing.
