Surgeon Specializing in Gynecology? Treating Rectocele and Cystocele

Hi, I suffer from a rectocele and cystocele for 7 years now. I'm looking for a surgeon who's specialised in solving these problems. Aren't there any surgeons who are also gynaecologists? I mean, a vaginoplasty is not the same as a boobjob or a tummy tuck. I really prefer a specialist who truely understands how things work down there. Who can give me the name of one or more specialists(preferably on east cost). Thank you!
