Summary

It is common for women to sustain perineal trauma following their first vaginal delivery. Sometimes these can extend to the anal sphincter, and these are referred to as Obstetric Anal Sphincter Injuries (OASIs). Occasionally OASIs may not be detected at delivery. If these tears are missed they would not be repaired and this may lead to incontinence of wind (flatus) or of faeces, both of which can have a significant impact on quality of life. The investigators would like to establish whether a 3D ultrasound scan probe placed outside the vagina can identify the anal sphincter defects and to investigate whether the use of TPUS immediately after primary repair of OASIs is an useful tool to minimise an inadequate repair. The investigators would also like to look at changes that occur to the pelvic floor muscles during labour and to identify injuries to the pelvic floor muscle (levator ani) by ultrasound. Such injury to pelvic floor muscle is associated with vaginal prolapse.
