While a woman is a mother, the baby has to pass through the vagina, which will more or less cause damage to the pelvic floor muscles. Light ones are basically normal through postpartum recovery and training. Slightly heavier ones will cause vaginal laxity, and heavier ones will show uterine prolapse, or even weakness in urination and defecation, which produces urinary weakness and constipation. The vaginal mucosa and muscles are very elastic, the mucosa can expand from 75px to 250px, and the muscles, both circumferential and longitudinal, can both expand and retract rapidly. Vaginal laxity is not simply a loosening of the vagina, but the muscles around the vagina become scarred and inelastic and loose after injury. The main muscles that hold up the vaginal muscles are the anal raphe muscle group, the vaginal genitourinary diaphragm, the perineal body muscle group, and part of the anal sphincter muscle group. Once these muscles are repaired, the vagina will be restored to its original state, and dysuria and constipation will be resolved. Nowadays, there are several misconceptions about vaginal repair: 1. Local injection narrowing. No filler is as elastic, as powerful and as sensational as the human muscle tissue. 2, Cutting away the loose vaginal opening and vaginal wall tissue. This will not solve vaginal laxity and will cause vaginal scarring and narrowing and painful intercourse. 3, Repair only part of the muscle groups. Partially improves vaginal laxity and falls short of vaginal renovation. We are talking about vaginal renovation today. The so-called renovation is to turn the old into the new as well, which requires us to repair all the damaged muscle groups, and at the same time reduce scar formation. We are now finding in pelvic organ prolapse surgery that the Cook Biodesign Soft Tissue Regenerative Repair Material has the ability to regenerate mucous membranes, muscles, and tendons and is fully absorbed, which reduces scarring, promotes healing of the damaged muscles, and reestablishes vaginal anatomy and function.
