Pelvic Floor

Pregnancy and vaginal birth are the main causes of pelvic floor disorders such as urinary incontinence and pelvic organ prolapse. The levator hiatus - the opening in the pelvic floor muscles through which the baby passes - can be measured on three-dimensional transperineal ultrasound at rest, during pelvic floor contraction and during a Valsalva manoeuvre. Its size and its ability to stretch have been related to how long labour lasts and to how the baby is eventually born, but the evidence comes mostly from women in spontaneous labour, in whom the exact time labour began cannot be established. Women having their labour induced offer a better model, because the time each stage of labour begins is documented. Recently, automated software has made the measurement of the levator hiatus fast and reproducible, which makes it realistic to use in everyday practice. This prospective observational study will enrol 140 women with a singleton pregnancy at 36 weeks or more who are scheduled for induction of labour. Before induction begins, each woman will have a transperineal ultrasound scan of the pelvic floor at rest, on maximum contraction and on maximum Valsalva. The scan does not involve any vaginal probe, radiation or injection, and takes about 15 minutes. The times of each phase of labour, the way the baby is born and the condition of the perineum after birth will be recorded prospectively from the clinical record. The scan will be repeated before hospital discharge and about one month after birth, together with validated pelvic floor symptom questionnaires. The main question is whether the area of the levator hiatus measured on Valsalva before induction is related to the duration of the active, pushing phase of the second stage of labour. The study will also examine the duration of the first stage, the mode of delivery, and how the pelvic floor changes in the first month after an induced birth. Study procedures do not influence clinical care in any way: induction and labour are managed according to standard departmental protocols, and the research ultrasound results are not disclosed to the clinical team.

The goal of this observational study with an embedded pilot clinical trial is to learn how the pelvic floor recovers after vaginal childbirth and whether early individualized pelvic floor muscle training can improve recovery in people who experience pelvic floor symptoms after vaginal delivery. The main questions it aims to answer are: * How do pelvic floor muscles and surrounding tissues change and recover during the first year after vaginal childbirth? * How are these structural changes and their recovery related to urinary, bowel, and vaginal symptoms? * In participants with pelvic floor symptoms after vaginal childbirth, does early individualized pelvic floor muscle training improve symptoms and support structural recovery compared with usual care? Researchers will compare participants who receive the early pelvic floor muscle training to those receiving standard postpartum care to see if the training helps improve pelvic floor function and reduce symptoms. Participants will: Attend clinic visits at six weeks, and six months after childbirth Complete questionnaires about urinary, bowel, and vaginal symptoms, as well as physical activity and quality of life at six weeks, and four, six months, and twelve months after childbirth Undergo clinical pelvic floor assessments, including vaginal palpation of muscle strength, tone, and perineal body stability Have ultrasound examinations of the pelvic floor to assess muscle structure, tissue integrity, and perineal body morphology For those in the pilot trial, participate in an early, individualized pelvic floor muscle training program This study will provide important information about how the pelvic floor heals after childbirth, how structural changes are linked to symptoms, and whether early personalized training can help prevent long-term problems.

The purpose of this clinical investigation is to collect clinical data about the ProGYNious Mesh based on a prospective clinical investigation. The primary objective is to verify the treatment outcome and success of the ProGYNious mesh implant in pelvic organ prolapse repair. The secondary objective is to confirm the safety, risks, complications and quality of life of ProGYNious as an implant for pelvic organ prolapse repair.
