For women with congenital vaginal agenesis and sexual needs, creating a functioning neovagina is a practical therapeutic schedule. Colpopoiesis using the sigmoid intestine were more reported in the literatures. Though the incidence of neovaginal prolapse (NP) is relatively low (3-8%), it does bring great inconvenience to patients, and expose gynecologists to tough challenges. Hereon, we report a case of NP 10 years after sigmoid colon vaginoplasty that was successfully repaired by laparoscopic sacro-colpopexy with a mesh, hoping to provide meaningful evidence for this rare situation.
