When transiting Uranus opposes natal Saturn, the person's foundation is really shaken up, and it indicates they may enter into a completely new way of experiencing life, the old way abandoned. Particularily if Saturn is very important in their chart, angular for example.
One would then assume that until the next Saturn Return, this theme would repeat itself.
In 7 years, a major step will have to occur in potentiating this new way of being, breaking out of the shell of what is happening right now in your life and your new reality. And then 7 years after that, you will be able to see objectively the positive and negative aspects of your present discoveries, and have the oppurtunity to either continue with them or give them up, in part.
Either way, make sure what you are doing is balanced. Oppositions are all about taking "a bit of this and a bit of that," and staying away from "the edge," staying in the middle. This is hardest at this time, for all of us. Saturn and Uranus are total opposites! And they are opposite !
Saturn is really the reality itself. If Uranus opposes it, it challanges the old ways of being to do something more advanced. During a Saturn Return, this could create a very uncomfortable feeling to say the least. You may feel that all you had done in your life is for some reason not any good, because there are younger and more awesome things being born constantly. You may feel old and become jealous. Don't let this hold you back, but use it positively. Don't let any feelings like that become rooted into your psyche, because they will repeat.
Hope this helps.
Are you 1979? That was an awesome year !!

You are blessed in all you do !
