Unable to find enough patients who accept randomization of surgical procedures.

The primary objective of this study is to compare the function results between two methods for surgically repairing rectoceles: vaginal versus endo-anal surgery. Our working hypothesis is that the relatively new type of endo-anal surgery will result in better voiding function compared to the traditional vaginal surgery.
