Yes, I had a rectocele and a repair, along with a hysterectomy. However, the repair hasn't helped with the BMs and a lot of the problems I experience have been described here, including manually helping and having altered sensations or none at all that I need a BM or when I have finished.
After my op follow up, I was referred for a defaecating pictogram (MRI, only on pelvic floor). This did not show anything wrong, other than not being able to expel the gel they put in, which was noted. I have been referred for physiotherapy, which I have had to postpone since November as I have been ill. I have an appointment in a couple of weeks. I can let you know about the appointment if you are interested. This is not the usual pelvic floor physiotherapy, different speciality.
It can be distressing, inconvenient and uncomfortable and not something easy to talk about. BMs take a while, not so bad at home, not very funny out and about, and distressing when in hospital in a ward where there wasn't enough toilet facilities. I have IBS, with a tendency to constipation, but manage to keep my stools soft most of the time, but it doesn't stop this difficulty.
