Abstract

OBJECTIVES:

Prolapse procedures with uterine preservation offer an alternative to colpopexy with hysterectomy. Few studies have examined the differences in anatomic or subjective outcomes following sacral hysteropexy versus sacral colpopexy with hysterectomy. This study sought to compare the ability of sacral hysteropexy and sacral colpopexy with hysterectomy to resist downward traction as an estimate of apical support in human cadavers.

METHODS:

Sacral hysteropexy was performed on unembalmed female cadavers. A metal bolt/washer was threaded through the uterine fundus, down the cervical canal. and out the vagina and fastened to a waxed surgical filament, which ran over a fixed pulley at the table's end. Successive weights were added to provide increasing loads on the uterine fundus, and the distances traversed by the fundus were recorded. The same process was repeated after completion of a total hysterectomy (with vaginal cuff closure) and subsequent sacral colpopexy in the same specimen. Data were analyzed using paired-sample t test and repeated-measures analysis of variance (Sigma Plot version 13.0), with P ≤ 0.05 considered statistically significant.

RESULTS:

Eight female cadavers were utilized. With the addition of each weight, the average distance traversed by the uterine fundus or vaginal cuff gradually increased. There were no statistical differences in the distances moved by the apex between sacral hysteropexy and total hysterectomy/sacral colpopexy.

CONCLUSIONS:

These results suggest that functional support provided by sacral hysteropexy and sacral colpopexy with hysterectomy may be similar. Further studies are needed to correlate these findings with patient satisfaction, which may vary despite similar anatomic results.
