Four cases of Mayer–Rokitansky–Küster–Hauser syndrome treated via non‐surgical vaginal reconstruction using uterine cervical dilators

Abstract

Vaginal creation is the standard treatment for Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome. Although non‐surgical method is recommended as a first‐line treatment in the American College of Obstetricians and Gynecologists guidelines for gynecological practice, it is not commonly performed in Japan. At our hospital, vaginal dilation using uterine cervical dilators (Hegar's dilator) is performed for patients with MRKH syndrome. We report four cases successfully treated with vaginal dilation. After the examination, patients were instructed to practice daily self‐dilation at home. The initiation size was No. 13 with 10.5‐mm diameter. After the vaginal cavity was dilated to a depth of 6 cm, the size of dilators was gradually increased until No. 30 with 25‐mm diameter in a tip and 28‐mm diameter in a trunk. The duration required to achieve the outcome was 5–22 months. All cases were successfully treated without any severe complication.
