In life, many middle-aged and elderly women often experience discomfort in the lower abdomen as they age, and even drop with lumps falling out of the vulva. In fact, these symptoms are the clinical manifestations of pelvic organ prolapse. According to statistics, about 75% of women will suffer from different degrees of pelvic organ prolapse. So how does pelvic organ prolapse develop? We can compare women’s pelvic floor to a “hammock” made up of muscles, fascia and ligaments, and self-adjust the tension according to environmental changes, the hammock is the bladder, uterus and rectum and other organs in the pelvic cavity. As we age, the support of the hammock is gradually weakened by pregnancy, childbirth and estrogen decline, resulting in relaxation and collapse of the hammock, thus causing the pelvic floor organs such as the bladder, uterus or rectum to drop. In addition to mild prolapse, moderate to severe prolapse is classified as symptomatic prolapse, which affects the patient’s quality of life and requires surgical treatment. Nearly 54% of patients with symptomatic prolapse have moderate prolapse, nearly 11% have moderate or severe prolapse, and nearly 36% have severe prolapse (II to IV on the POP-Q scale). The traditional treatment of pelvic floor prolapse is to remove the prolapsed uterus and bulging vaginal wall and repair the damaged fascia with sutures, or to fix the bladder in suspension. This procedure not only shortens the length of the vagina by removing the uterus without lesions, which is very traumatic, but the suspended structures are still sutured to the already flaccid pelvic floor structures, so the recurrence rate is high. Recently, with the development of surgical mesh materials, various mesh pelvic floor repair systems have come into being, and the treatment of pelvic floor organ prolapse has entered a new era of minimally invasive mesh implantation. The use of mesh for pelvic floor reconstruction has the advantages of no open abdomen, little trauma, fast postoperative recovery, and less recurrence. For example, Prolift mesh pelvic floor reconstruction surgery, which has been used abroad for many years, has become the gold standard for the treatment of severe prolapse. However, the number of patients with moderate prolapse far exceeds that of patients with severe prolapse. In response to this clinical need, Australian female pelvic floor prolapse specialists introduced the Prosima mesh pelvic floor reconstruction surgery for patients with moderate prolapse in 2009 after five years of clinical development. This procedure is more minimally invasive than the Prolift procedure, is non-invasive, and improves post-operative comfort and sexual quality of life with satisfactory clinical results. This is a great blessing for women who suffer from pelvic organ prolapse.
