This series covers information sheets about Pelvic Organ Prolapse (POP) from professional health organisations. These pages, though they don't necessarily go into a great deal of detail, are a good place to start. They help you gain a clear understanding of POP.
The Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) has put out a short information sheet about prolapse: Prolapse of the Pelvic Organs.
Though it has some information on what is referred to as 'conservative treatment' (which may include monitoring, physiotherapy or insertion of a Pessary), its main focus is on surgery.
The main strength of this fact sheet is that it includes a video that explains laparoscopy (a common form of prolapse repair surgery), and shows what happens during a laparoscopy.
While I encourage women to be as informed as possible about their prolapse and any treatment they undertake, you know yourself best. If watching a video like this will make you more anxious about surgery, then it may be better to read about what happens during the surgery rather than watching it.
Warning: The end of the video shows how laparoscopy can be used to treat Ectopic pregnancy. Stop it before the end, or do not watch it at all, if this will be distressing to you.
