Vault prolapse of sigmoid neovagina 26 years after vaginoplasty in Mayer-Rokitansky-Küster-Hauser syndrome: a case report

Various operative methods have been devised to create a neovagina for patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. Sigmoid vaginoplasty, a common modality for vaginal reconstruction, is believed to have satisfactory long-term anatomical and functional results. We herein report a patient with MRKH syndrome and vault prolapse of a sigmoid neovagina 26 years after vaginoplasty. Biopsies from the neovagina revealed colonic mucosa. Bilateral iliococcygeus fascia fixation of the neovaginal vault was performed vaginally. The patient had a low Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-12 (PISQ-12) score preoperatively, which further decreased postoperatively. Therefore, the surgery failed to achieve a good functional result. No recurrence of the prolapse was observed 2 years postoperatively.
