OBJECTIVE To release a new design for a detachable porous vaginal mold to facilitate reconstruction of a modified McIndoe vaginal mold. METHODS We constructed a detachable, porous vaginal mold with a plastic laboratory centrifuge tube with multiple holes throughout the entire tube. METHODS Patients in a national tertiary medical center. METHODS Four patients of congenital vaginal agenesis received the modified McIndoe procedure. METHODS Two full-thickness skin grafts removed from the inguinal region were used to cover the detachable porous plastic vaginal mold; the mold was then inserted into the neovaginal cavity and kept in place by sutures between the mold and labia majora. The vaginal mold was removed on day 12 after the operation. All patients adhered to the follow-up instructions. METHODS Description of the accessibility of a neovaginal mold. RESULTS The vaginal mold is helpful in taking care of the vaginal wound in that it allows easy removal of wound secretion and local cleansing douches. All grafts took completely and recovered well. No detachment of the graft occurred. CONCLUSIONS The advantages of the detachable porous vaginal mold made from a plastic centrifuge tube are that it is readily available, allows for easy wound care, and, as a fixed point, prevents graft detachment or inversion and thus may lead to a promising result for a modified McIndoe vaginal reconstruction.
