Can a ring pessary have a lasting effect to reverse uterine prolapse even after its removal?

A vaginal ring pessary for uterine prolapse has been considered only to reposition the uterus during fitting and is thus palliative. A ring pessary was fitted in a 71-year-old woman with uterine prolapse to reposition the uterus. When the pessary was removed after 73 months, the prolapse disappeared and did not recur. In another five patients with uterine prolapse who were fitted with a ring pessary, prolapse also disappeared after pessary removal. In these six patients, the median duration of pessary implantation and observation after its removal was 27.5 and 42.0 months, respectively. In some women, a vaginal ring pessary may reposition the uterus not only during implantation but also after its removal.
