This study aimed to compare the ability of abdominal sacrocolpopexy (ASC) with concomitant total vs supracervical hysterectomy to resist downward traction as a measure of functional anatomic support in human cadavers.


Supracervical hysterectomy was performed on unembalmed cadaver specimens, followed by ASC attaching polypropylene mesh to the posterior cervix/vagina only and then the anterior and posterior cervix/vagina. Using a metal bolt placed through the cervix tied to a filament passing through a fixed pulley system, successive weights of 0.5 to 3.0 kg were added to provide increasing loads on the apex (cervix), and the distances traversed by the apex were recorded. The same process was then repeated in each specimen after removal of the cervix (with vaginal cuff closure). One-way and repeated-measures analysis of measure was used for between-group and within-group comparisons, respectively, with P ≤ 0.05 considered statistically significant.


Eight cadavers were examined. At lower weight loads, pulling distances in the 4 groups examined were similar and were not significantly different with the presence or absence of the cervix. At weight loads of 2.5 kg or greater, we noted a trend of increased pulling distances when posterior mesh only was used vs when anterior/posterior mesh was placed, although this difference was not significant. Interestingly, there was tearing of the vaginal wall or partial separation of mesh/sutures attachments to the vagina noted in 3 specimens.


This study showed no differences in the ability of the cervix (after supracervical hysterectomy) compared with the vaginal cuff (after total hysterectomy) to resist downward traction of successive weights after ASC. Clinical trials are necessary to correlate these findings with prolapse recurrence rates and patient satisfaction following these procedures.
