How Long Does A Cystocele Surgery Take?

I am having cysteole surgery in a few days, how long does this surgery normally take??? And can my rt ovary be removed at the same time?? I don t have my left ovary.. How long of a hospital stay.... Nothing is wrong with my rt ovary but the physican says she may go ahead and take the ovary . I am 60 yrs old. Thank you:):)
