ANATOMY
The pelvis consists of three compartments:
- Anterior compartment (Bladder and Urethra)
- Middle compartment (Vagina and Uterus)
- Posterior compartment (Rectum)
The bony pelvis is lined on the inside by different muscle groups
and the muscles are covered with a layer of fascia called the endopelvic
fascia. The endopelvic fascia covers both side walls of the pelvis.
The endopelvic fascia also forms two transverse layers of fascia which
is attached laterally to the vertical layer of endopelvic fascia.
The anterior transverse layer is called the pubocervical fascia
and extends from the pubis anteriorly to the cervix posteriorly and
is also laterally attached to the arcuate tendons which are areas
of condensation of the lateral pelvic fascia. This layer supports
the bladder and urethra and prevents the bladder from sagging into
the vagina. The posterior transverse layer is called rectovaginal
septum and extends from the perineal body anteriorly to the cervix
posteriorly. This layer supports the rectum and prevents the rectum
from bulging into the vagina.
During childbirth the baby passes through the middle compartment
and these two transverse layers of fascia are pushed anteriorly and
posteriorly. This may cause stretching or tearing of the fascia and
it may also be separated from its attachments to the side walls of
the pelvis. The result is that the support of the bladder and rectum
is damaged with either bladder prolapse (cystocoele) or rectal prolapse
(rectocoele). |
SACROPEXY / PROMONTOFIXATION
The most logical way of repairing these two layers of fascia would
therefore be to strengthen these two layers by interpositioning of
mesh between the bladder and the vagina and between the rectum and
the vagina. The laparoscopic approach provides access to these spaces
without having to cut through any important structures. The anterior
mesh is inserted between the bladder and vagina as low as possible
to the level of the bladder neck. The other end is then fixed to the
promontory of the sacrum to provide a strong bony support at the top.
The second layer of mesh is positioned between the rectum and vagina
and is fixed inferiorly to the pelvic floor muscles, laterally to
the uterosacral ligaments and is also attached to the promontory of
the sacrum at the top. The extension of the mesh to the promontory
of the sacrum replaces the lateral ureterosacral ligaments which extend
as high as the first sacral vertebra. This part of the uterosacral
ligament is often very weak and damaged and cannot support the vaginal
vault or uterus as it should do.
PARAVAGINAL REPAIR
As the pubocervical fascia is often torn away from the lateral
pelvic walls this defect has to be repaired by laparoscopy to
the area where the pubocervical fascia is separated from the
pelvic wall. The gap is closed with ethibond sutures and also
fixed to Cooper's ligament to keep it well supported.

SLING OR BURCH COLPOSUSPENSION
If the patient has stress incontinence due to intrinsic sphincter
deficiency, then a suburethral sling is indicated. If the patient
has stress incontinence due to hypermobility of the urethra, then
either a suburethral sling or laparoscopic Burch colposuspension could
be performed to support the urethra.
