Rachel, a friend of mine had the op and things have been much better for her. But it doesn't always work and can make things worse in about 10% of cases I think. The best thing is to really work those PF muscles first. The standard PFE are great, but if you see a physio (some specialise in these "women's issues") they can give you a range of targeted exercises. I strongly recommend trying this before having surgery. Pilates is also great as it helps you work the PF. GL.
